There is no such thing as fate, everything is a test, punishment or compensation.

This year's severe cold seems to be particularly long!
It was early spring, and the small town was still shrouded in dryness and dullness. The cool wind was mixed with dust, which made people feel extremely uncomfortable to breathe, and the skin was burning like being pricked by needles.The street is gloomy and desolate. The flowers, plants and trees on both sides only sprout a few sporadic shoots. Most of the pedestrians passing by wear cotton caps and masks, wrapping themselves tightly, only revealing a pair of lifeless eyes.

On the street, a bus just unloaded passengers and drove out of the bus stop.It’s past the rush hours for work and travel, and not many passengers get off the bus, only two young girls and a bloated middle-aged woman, and at this time a pair of eyes full of extreme desire and excitement are standing between them Look back and forth.

It was a man. After several inspections, he unexpectedly fixed his gaze on the middle-aged woman—he finally got her.The middle-aged woman had a pale complexion and tired eyes. She swayed her limp body across the road and walked towards a residential area across the street. She looked extremely tired.The man knew it was because she just got off the night shift, and he couldn't help but remind him of the nurse who just got off the night shift in 2001.

The man followed the middle-aged woman's back without slowing down.Of course, he needs to be particularly vigilant and careful, but fortunately, most passers-by are in a hurry in such a ghostly weather, and they don't have the heart to pay attention to whether a pretty old woman is being followed, and he himself is well protected and covered measure.

The man gradually followed the middle-aged woman into the depths of the community. Seeing her walk into a unit building, the man also quickened his pace, and at the same time kept looking around, looking more cautious-he had to make sure that no one was there at the moment. After noticing his appearance, of course, after entering the building, he must not be witnessed by other residents, even if he is only glanced at inadvertently, he must give up this goal, forever and completely, otherwise one day, he will Get in touch with the death of a middle-aged woman!

As for other situations, the man has already prepared a contingency plan in his heart.

For example, whether there are anti-theft doors in residential buildings, and if so, whether to choose to give up or find excuses to enter; for example, under what circumstances is it suitable for a lightning raid, and under what circumstances should a door-knocking strategy be adopted; another example is how to deal with it after finding out that there are other people in the house ...

So how do you know that there is no one else in the target family?This requires some observation, summarization and experience, as well as some luck!For example, from the point of time: Usually during the daytime on weekdays, the men and children in the family have to go to work and school, and the target person has the highest probability of being alone at home. Even if there are people, most of them are elderly people. It is not difficult to deal with it.Another example is behavior: Most people are exhausted after working all day, and they don’t bother to take out the keys before they get home. They will choose to knock on the door and let their family members open it. If a person takes the key out of the bag and opens the door without hesitation , it probably means that there is no one at home; if a person is carrying a lot of things in his hand, puts them down on purpose, and then takes out the key to open the door, then it can be more confirmed.And if you are patient, follow up a few more times, and fully confirm the situation before you start, it will be safer!In short, men should keep in mind that one - the ultimate success is always inseparable from prudence, patience and luck. It is not necessary to demand that every hunt has a harvest.

Of course, this time, it can be said that he likes all the conditions.

The middle-aged woman lives in an old residential building, and the anti-theft door has been damaged for a long time. At this moment, there is no one in the corridor, and the middle-aged woman is not vigilant about his following. As expected, she walked out without hesitation. Take the key out of the bag and open the door...

The moment the middle-aged woman opened the door, the man reached into the bag, held the sharp weapon tightly, walked a few steps quickly, and caught up with the middle-aged woman... She felt him and subconsciously looked back, but she didn't expect it at all. The man in front of him was actually a disciple of the devil!

第三起“98·1·13”、第四起“98·1·19”、第九起本年“1·20”案件，作案手段与上述案件基本相同，且刀伤创口特征与上述案件的凶器吻合。

Various technical surveys and appraisals showed that the above cases were committed by the same person, and they were classified as "serial murder cases of sexual perverts"!
After reading the dossier, Gu Feifei raised her head and found that Wu Guoqing's eyes were slightly red and his expression was slightly unnatural. She was puzzled for a moment, then suddenly understood, and asked tentatively, "Mr. Wu, you should have participated in these cases, right?"

"Yes. These cases have been traced from the local government to the General Administration for more than ten years, but the murderer has never been found." Teacher Wu nodded slowly, with a somewhat awkward tone, paused, and then said, "Then What frustrates us the most is that we don’t know when the murderer will stop committing crimes, so after research, we think we should take appropriate measures to warn the public to be vigilant when traveling to reduce injuries; at the same time, we hope to get their help , identify suspicious people around them, and form a psychological deterrent to the murderer to the greatest extent. Around mid-December 2004, we briefly announced the case through the local media, and offered a large reward to encourage the public to provide clues. I don’t know if this is the way It's really effective, although there are few valuable clues since then, the murderer has disappeared." Wu Guoqing stopped talking again, sighed and said: "We all know that from the perspective of criminal psychology, this kind of person is I can't stop, so after so many years, I once took it for granted that the murderer was already sick or passed away due to an accident, but I didn't expect him to reappear so suddenly and kill two people one after another. Imagine!"

"Well, it's really rare. Serial killers rarely die at the peak of their crimes, and they commit crimes again after so many years." Gu Feifei's face was a little puzzled, "But I still have some doubts about the joint investigation: Ninth In this case, which is the first crime this year, the murderer did not leave any physical evidence. Is it too hasty to determine the same crime based on the criminal method and knife wound? The same wound only shows that the murderer used the "same type of murder weapon", and I I also noticed that the method of the crime is almost exactly the same as the '88·5·26' case, which is very similar to copying the crime."

"No, this just reflects that the murderer is announcing his return!" Wu Guoqing shook his head twice and said, "You have also seen that the murderer almost mutilates the victim's body with a knife every time he commits a crime. For him, it may be a channel to vent certain emotions, which is very important to him. Every knife should have a deep memory, so when we reported the case to the public, we deliberately made a mistake in the number of knife wounds, hoping that he would because of this To refute us in some way, so as to expose the loopholes."

"In other words, the number of stab wounds is actually hidden evidence, only the real murderer and us police will know!" Gu Feifei was somewhat unwilling, and said after pondering, "I think it is still necessary for Teacher Han to study it again!"

"That's good, but after all, behavioral scientific analysis is only an auxiliary means. Remember, you still have to follow the evidence in handling the case." Wu Guoqing stared at Gu Feifei and instructed.

"I understand!" Gu Feifei nodded solemnly, and after being quiet for a while, she raised her voice slightly and said, "By the way, Xiao Du has asked me to report, and he insists on going to the case because of pestering, do you think it's okay?"

"Is his psychological counseling over?" Wu Guoqing asked with concern.

"It was over last week. I have read the report of the psychological counselor, and all indicators are normal!" Gu Feifei responded.

"Then take him with you!" Wu Guoqing lowered his head and thought for a while, then raised his head and said emphatically, "This kid is fatal, if the bullet misses by an inch, it will be over. However, those who have been shot will feel somewhat shadowy in their hearts, and they may lack stimulation now. So Yuan didn’t show up, you and Mr. Han should pay more attention, if you find that he has signs of PTSD (post-traumatic stress disorder), you must do a good job of counseling in time.”

"Don't worry, I'll watch him!" Gu Feifei promised to stand up from the chair, "If you have nothing else to do, I'll go and arrange the itinerary."

"Go!" Wu Guoqing waved his hand, and said in a sad tone, "Xiao Gu, I thought about it for a while, your attitude just now was right, you must be cautious when you go down this time, and don't rush for success. We have missed too much This time, let’s try to end it this time.”

"Definitely!" Gu Feifei looked at Wu Guoqing with piercing eyes, and said firmly!

A police academy in the north, a lecture hall.

When Han Yin walked in with a gentle smile on his face, the crowded and noisy classroom immediately quieted down. He nodded slightly, gestured to the students politely, and walked onto the podium.

He put the laptop on the desk in front of him neatly; he turned it on and pressed the power button; then he took off the watch on his wrist and placed it lightly on the upper right corner of the desk; Put them at the upper left corner of the desk at the same level; then took off his coat and hung it on the hook by the door of the classroom; then, walking back to the podium, he unbuttoned the cuffs of his shirt and rolled up the two sleeves twice. ... After finishing the habitual pre-class preparations in an orderly manner, Han Yin took out a piece of chalk from the chalk box on the desk, turned around and wrote a line of titles on the blackboard.Students familiar with his lecture style know that these are probably the only few words he will write in a class.

Han Yin rubbed his hands, wiped off the chalk dust on his hands, stepped off the podium, and approached the students' seats.He likes to communicate closely with the students, so that he can directly and clearly observe the students' emotional feedback.His voice was as calm and friendly as ever:

"Students all know that the conventional method of handling cases is mainly around the criminal, but for our major, the profile of the victim and the criminal are equally important. Today we will talk about the importance of behavioral scientific analysis, and it is also The 'victim study' of the first link."

"We have learned before that there are three elements in judging serial crimes: criminal methods, criminal characteristics, and victim selection. This shows that 'victim research' is an important indicator of serial crimes. For example, in the process of research, we find common points or intersections of cases It may be that the victims are roughly the same gender and age group, or that the external conditions such as facial features or hairstyle are similar, or that they participated in a certain incident together, or that they appeared in the same place inadvertently, similar to a bus Stations, subway stations, libraries, etc. In short, by studying the victims, we can effectively connect the background, interrelationships, investigation directions, etc. of the cases.”

"And its more important significance for behavioral scientific analysis is that when we fully understand the characteristics of the victim, and then combine the theories we have learned to summarize and summarize, we can roughly infer the criminal's age range, external conditions, Mental status, marital status, IQ status, and even psychological motivation, etc.”

"Let's start with an in-depth understanding of the age composition of the victims: Suppose we want to solve a serial rape and homicide case targeting female targets. The age composition of the victims in this series of cases spans a very large range, from teenagers to 60-[-] years old. There are, summing up the past, we can draw an inference: this is a revenge or fantasy crime against the "whole female group"; if it is another situation, the whole crime spans several years, and the age of the victim seems to be increasing with the murderer's age. This can also lead to the same inference as the above-the murderer's fantasy object is "the whole female group", and there is no specific candidate; if the crime spans several years, but the age of the victim is always the same, then this It shows that the case is a compensatory crime, and the victim may be a substitute for a specific person; and if we find that most of the victims are elderly when we sort out the whole case, or the older ones who committed the crime earlier, then It relatively reflects that the age and experience of the murderer are at an immature stage, and it is very likely that the crime was committed by a teenager... Of course, we can also make some extensions from the above inferences, for example: the murderer may have been abused by women, suffered repeated setbacks in his relationship, and had sex with women. Difficulty communicating, having both fears and fantasies about women, etc."

Ding Lingling.

Han Yin was in the midst of his lecture, when he suddenly heard a text message from behind him, he hurriedly apologized to the students, walked back to the lecture table, picked up his phone and wanted to set it to vibrate mode, and scanned Eye the content of the text message on the screen: I know you are in class at this time, and if you have a case you like, come to Mining City quickly!
Mining city?Is the famous unsolved case about to be reopened?Han Yin's heart skipped a beat, and he couldn't calm down anymore.From the perspective of society and human nature, he certainly hoped that such a case would never happen, but from the professional perspective of behavior analysis and criminal psychology research, it is definitely a very valuable case, and Han Yin has counted in his heart that it has happened in China Among the many unsolved cases, the "serial rape and murder case in Yekuang City" is definitely the one he wants to challenge the most!

Han Yin looked at his watch, there was still some time before the end of get out of class, he thought about it, and smiled apologetically at the students in front of him: "I know the students are looking forward to the next case discussion, but today I want to say sorry to everyone Alright, because there is an ongoing case that needs to be resolved, so... get out of class!"

Section [-] Site Reconstruction
Yekuang City, located in the northwest of my country, is a heavy industrial city rich in mineral resources and coal resources, with non-ferrous metallurgy as its pillar industry.The total area is about 1.8 square kilometers, and the population is close to one million. Roughly one-third of the population works in non-ferrous metallurgical enterprises.

According to the past practice of handling cases, if conditions permit, even if the local police have a very detailed investigation and inspection report on the scene and physical evidence, the support team will still rebuild the scene again, and it is possible to be investigated by the grassroots through in-depth excavation of simulated crimes. At the same time, it makes the analysis of criminal behavior more intuitive and three-dimensional. Therefore, after Han Yin rushed to the local area to meet with the support team, he immediately rushed to various crimes, accompanied by Liu Fuzhi, the head of the Criminal Police Detachment of Yekuang City. on site.

There are two districts under the jurisdiction of Smelting City, Xiangyang and Fuping. The murderer's first eight crimes were concentrated in Xiangyang District. Only two cases occurred in Fuping District this year. Due to the relatively short time, the crime scene remained intact, and the group rushed to the latter first. go.

The two crime scenes are not far apart, roughly less than one kilometer away. There are many small and medium-sized factories in the surrounding area. The residential areas are mainly factory and mine family buildings and low-end open communities. Most of them have no anti-theft doors installed, and camera surveillance probes are even rarer. , I don't know if this is one of the reasons why the murderer moved the crime area.

In terms of appearance and internal layout, the buildings at the site of the "1" case are relatively better, but the construction time has been more than ten years.In a house with two bedrooms and one living room facing south, the living room is connected to the kitchen when the door is opened. Blood splatter traces of varying degrees.Carefully observe the characteristics of the bloodstains, it can be seen that the blood droplets are relatively dense, similar in shape and size, and in the same direction. The thin ends of the bloodstains all rush upwards, which is consistent with the medium-speed splatter formed by carotid artery hemorrhage.This shows that the fatal cutting in this case occurred at the moment when the victim opened the door, and the victim was facing the door at that time, which means that the murderer attacked the victim from the front.

Then, the distorted direction of the bloodstains showed that the murderer dragged the victim with one hand, without the slightest pity in his emotions, just like dragging a dead cat or dog.The victim was dragged to the kitchen and stopped. The white marking line accurately outlined the position and position of the corpse. Combined with the previous on-site inspection report, it can be known that the victim was naked at the time, with his legs stretched to the maximum, and his lower body was completely naked. The private part is rushing towards the door.This is obviously very deliberate, as if the murderer felt that she had to expose her unknown and shameful side to the world, and let the world humiliate and flog her...

Of course, humiliation is not enough for the murderer, he also wants to destroy her, so he frantically stabbed the victim's body again and again with a sharp weapon.Usually, if this kind of excessive killing is just an accidental factor in a series of cases, it will be regarded as the murderer's initial crime, which is a manifestation of immaturity and confusion; Actions may be a manifestation of anger and sexual repression.This kind of psychological motivation is not uncommon, and Han Yin has seen it in many cases including the "Yangquan series of murders".

Generally speaking, this case is roughly the same as the previous cases in terms of criminal habits and criminal marks.

The scene of the "3" case was in a family building of a factory and mine.Although it has been around for a long time, the conditions are not bad. Unlike the more common tube buildings, cooking and going to the toilet have to be in the corridor, but its interior space is small and the layout is relatively narrow.The entrance is a corridor, and then leads directly to a small balcony for cooking. On the right hand side of the corridor is the bedroom and a very small toilet.A large area of ​​bloodstains also gathered at the door, but the splattered distribution and direction of movement were completely opposite to those of the previous case. Although there were some bloodstains similar to splatters on the door, they were obviously scattered and varied in shape and size. It looks like it should be left by the murderer swinging the murder weapon.In short, restore the incident: the victim should have just entered the house, and the murderer launched a surprise attack behind her.

Next, the additional process of the murderer venting his abnormal psychology is similar to the previous case, except for one more link: he tied a red cloth around the victim's neck, which is a supplement to the criminal mark and a perfection to the fantasy , which of course means that he will commit crimes again...

Based on the above information, the support team had a preliminary understanding of the murderer's personality traits. At the same time, several questions arose that needed in-depth analysis: Just like back then, the murderer was too cautious, and he chose a low-risk area for his comeback. To commit a crime, it is obviously safer to knock on the door of the target's room before committing the crime.So, how did he gain the victim's trust and knock on the door?Is it possible that they knew each other?The murderer's marking actions during the crime reflect his deep resentment and resentment towards women. So what is the person or event that stimulates him?What is the meaning of the red cloth tied around the victim's neck?Is it about the victim, or just the killer's fantasy? ...

Chaoyang District is the political, economic and cultural center of Mining City. Government agencies, major bank branches, corporate office headquarters, luxury hotels, high-end shopping centers, etc. are all located here. Most of the residential areas have been re-planned. It was almost demolished, and the original so-called crime scene basically did not exist. Only the second "94·7·27" case, the fifth "98·7·30" case, and the eighth "02·2" case remained. The original site of the "9" case.

"'Huixun' can be regarded as a time-honored name in smelting and mining. Its history can even be traced back to the 20s and 40s. After a series of relocation, reconstruction, renaming and resale, it was not rebuilt by the Xiangyang District Government until the late 20s. , and restored the original name 'Huixun Hotel', the victim of the '80·02·2' case unfortunately died in a long private room on the third floor of this hotel." Liu Fuzhi introduced to the support group, "There used to be It can also be regarded as a high-grade leisure and entertainment accommodation place in Xiangyang District. It has all kinds of guest rooms, restaurants, karaoke halls, and bathing facilities. It was very difficult. However, just like many state-owned and collectively-owned hotels, with the influx and rise of a large number of foreign chains and local private hotels, Huichun Hotel did not escape the fate of bankruptcy in the end. It was resold a few years ago To a private company."

Standing in front of the now unrecognizable Huichun Hotel, which is undergoing a new round of renovation, they think that this place is actually of little significance to the investigation of the case, but the history introduced by Team Liu can still allow the support team to capture some clues.

The second "94" and the fifth "7" cases both occurred in the courtyard of the Power Supply Bureau of Mining City. The victim in the previous case was a temporary worker in the cafeteria. Soon, he lived in the dormitory building on the left side of the north gate of the compound.It is still a dormitory building for the employees of the power supply bureau. Single people live on the second floor, and the victim lived in the innermost room on the second floor.In the latter case, the victim was a little girl. Her parents had just been transferred to the power supply bureau not long ago. The family lived in the building of the measuring station on the right side of the north gate of the compound.This building has not changed much now, and it is mainly used for offices. Back then, the victim's family lived here temporarily because they had not yet been allocated a house.The two buildings are facing the street, but the entrance and exit are in the compound. Outsiders must go through the north gate to enter the building, and the murderer must know the daily routine of the two victims and their families very well. Does this mean that the murderer has some relationship with the power supply bureau? What kind of intersection?

"Captain Liu, besides this temporary dormitory building, does the Power Supply Bureau have a compound for family members?" Han Yin stood outside the north gate of the Power Supply Bureau, staring at the buildings on both sides, pondered for a while, and then asked.

"Yes, it's not far, it's over there." Team Liu pointed to the west of the power supply bureau, "It has been planned as a commercial housing complex, but the relevant supporting facilities have not yet been fully built, and there are no residents yet."

"Then should the original residents move back, or receive compensation and choose another place to live?"

"It's probably a relocation. Who doesn't want a house in the city center?" Team Liu said ambiguously again, "But it's hard to say, and I need to find someone to find out more about it."

"The more detailed the better." Han Yin frowned and urged.

"Okay, no problem." Team Liu nodded to Han Yin, and emphasized to Gu Feifei by the way, "Gu Team, if you have any information that needs to be verified and understood, please feel free to mention it. The team will fully cooperate."

Gu Feifei gave a "hmm" and said modestly: "Then I will trouble you!"

"You're welcome, you should!" Team Liu said carelessly.

They went through the main process of handling the case without stopping, and when they returned to the hotel where they were staying, they were exhausted. They declined the kindness of Team Liu and the leaders of the city bureau to host a banquet, and they had a casual meal at the fast food restaurant next to the hotel. They went back to their respective rooms.

However, there was a small episode when the room was allocated, and the "leading star" was Du Yingxiong.

The Municipal Bureau of Smelting and Mining was very considerate in terms of reception, and prepared a room for each of several people.But after getting the room card, Du Yingxiong insisted on asking the front desk to change him and Han Yin to a standard room with two beds, and kept yelling, "It's mainly for the convenience of discussing the case with Mr. Han."

Han Yin didn't care, but Gu Feifei knew that he likes to be quiet, especially when researching cases, so she gave Du Yingxiong a blank look and said, "Okay, go back to your own room quickly, don't disturb Teacher Han!"

"Are you sensible or not? Mr. Han needs an independent space to do profile reports, so why are you making trouble!" Ai Xiaomei said more bluntly.

"I definitely won't make trouble, I just want to observe closely and learn more!" Du Yingxiong raised his hands to promise.

"You can stay however you want, and if you talk nonsense, I'll ask the front desk to issue you a return ticket right away, do you believe it?" Gu Feifei said angrily, unmoved.

"Then... okay." Seeing that Gu Feifei was a little annoyed, Du Yingxiong murmured in a low voice with great reluctance.

"It's okay, it's really okay, I'm willing to live with Xiao Du." Han Yin said in a smooth manner.

"Hey, that's not right, I just realized it..." Ai Xiaomei asked Han Yin, "Mr. Han, why did you two get so close suddenly? What's going on?"

"Ah..." Han Yin froze for a moment, glanced at Du Yingxiong, and said, "Didn't Xiao Du mention it to you?"

"No!" Ai Xiaomi turned her head, pointed at Du Yingxiong's nose, and stared at him with wide eyes, "Say, what's going on?"

"It's nothing!" Du Yingxiong pretended to be mysterious, smiled ambiguously, and explained, "Didn't I be shot and hospitalized? The doctor said that I would have to recuperate for at least a few months before returning to work. I thought it was a waste of time." It's a pity, so I asked Mr. Han for some materials, and learned the practical application of criminal psychology analysis, which can be regarded as enriching myself, and I will have both civil and military skills in the future!"

"Well, I still know how to improve." Gu Feifei eased her face, smiled at Du Yingxiong, and then turned to Han Yin, "Is he successful? Is that the material?"

"Excellent. Xiao Du himself studied criminology and related psychology. He has a theoretical foundation, and he does not lack practice and has experience in handling cases. In some respects, he is easier to become a talent than school students. I also It is to select some cases for him to see, let him ponder on his own, and then discuss with me, and I am very satisfied with the results of the feedback.” Han Yin never said anything on the scene, and his sincere statement showed that he really liked the case. Du Yingxiong agrees.

Seeing that Han Yin had such a high opinion of himself, Du Yingxiong was a little embarrassed, and put on a modest look, saying: "The main reason is that Mr. Han's case is very detailed, and every small detail is marked in detail. It's easy to accept."

"Okay, let's forget about today, I won't be here for a while. I'm tired enough, go back to each room and take the time to rest!" Gu Feifei said to the two children, and also looked at Han Yin meaningfully, showing consideration and concern. The love goes without saying.

Said to go back to the room to rest, but how is it possible?It has always been the same in the past. Once he enters the state of handling cases, Han Yin sleeps very little. It's not that he doesn't want to sleep, but that there are too many complicated and messy things in his head, and he is always eager to solve the problem in the shortest time. Sort them out clearly, not to mention what can be said to be an "unprecedented" case now!

Looking at the series of perverted rape and homicide cases with similar crimes at home and abroad, including the most well-known "Jack the Ripper case" in the Whitechapel area of ​​England, the "Boston Strangler case" and "BTK serial massacre case" in the United States, Asia The "Hwaseong Serial Rape and Murder Case" in the neighboring country South Korea, and the "Yekuang City Serial Rape and Murder Case" currently under investigation, no matter their criminal methods, the number of victims, or the perverted and cruel acts of destroying corpses, are all worthy of praise. The world is shocking, and of course the most paradoxical thing is that except for the "BTK killer" who was arrested 31 years after the first crime, the rest are unsolved cases.

Then, through a horizontal comparison and summary, we can see that in the entire series of crimes, all the cases occurred before evening, or even in the morning in broad daylight, all of which were the most risky burglary crimes. One case of "Serial Rape and Murder Case in Yekuang City".In particular, the time span between the initial crime and the last crime, as well as the length of the cooling-off period from the pause in the middle to the next crime, are unique.

The biggest difficulty in dissecting the murderer in this case is that he committed the crime again after more than ten years, showing completely different personality characteristics from the past. In the previous eight cases, the murderer maintained his usual style, low-key and indifferent.Just like the "Boston Strangler" and "Hwaseong Serial Killer", they always pursue their own hearts and ignore the outside world's remarks.However, in the ninth case, the murderer copied the method used in the earlier case, which seemed to be a high-profile declaration of his return, and then in the tenth case, he perfected the link of criminal marking, as if he wanted to prove something, or wanted to It is necessary to test and challenge the ability of the police, so the personality characteristics of the murderers in the latter two cases are similar to those of the "BTK killer". They all have the desire to be strongly concerned by the society and the public!
Of course, just like the nature of criminal profiling itself, it is not science, but uses relatively scientific methods to summarize, induce, and deduce. Different dominant stress responses.Just like the "Yangquan series of murders" mentioned above, in the whole case, the murderer experienced an escalation from pure venting of anger to an escalation of desire to challenge the police to gain a sense of accomplishment, but this is only one aspect of the case, and Generally speaking, this transformation does not go beyond the category of antisocial personality.The difficulty of this case is just like what I just said, the murderer's personality change is opposite, so Han Yin needs to find two different sources of stimulation...

In addition, Han Yin also felt that the atmosphere of handling the case this time was very delicate, and it seemed that everyone was deliberately avoiding the urgency of the case in front of him.Especially Team Liu, who seems to be at least 50 years old. According to his own introduction, he has participated in the investigation of the case from the beginning to the end. Presumably no one is more eager than him to catch the murderer.However, during the daytime communication, he has been careful to hide his emotions, which actually made Han Yin feel a lot of pressure in his heart-after more than 20 years of police and robber tracking contests, with the death of one life after another, the murderer always escaped safely. This time it was obvious that everyone pinned their hopes of solving the case on Han Yin.To be honest, although he has indeed become a Terminator many times, he is not used to being regarded as a savior. Beat to death with a stick and become the center of crusade...

Han Yin's mind was in a mess and he was thinking wildly when his cell phone rang. After answering the call, Gu Feifei's voice came unexpectedly: "Are you still asleep? Tomorrow morning, Xiaomei and I will go to the technical department of the detachment to look for evidence. Clue. Do you have any arrangements, do you need me to communicate with Team Liu?"

"No, I'll take Xiaodu shopping tomorrow..." Han Yin replied unexpectedly.

"Oh...well, I got it." Gu Feifei on the other end of the phone was silent for a while, probably a little surprised, but then she responded lightly, of course she understood that Han Yin's arrangement was not just as simple as shopping.

Section [-] Footprints of Old Cases
Detachment Technical Department, Forensic Medicine Department.

The person who received Gu Feifei and Ai Xiaomei was a male forensic doctor who introduced himself as Wang.He is not tall, his hair is thin and sparse, mostly white hair, his face is shriveled and wrinkled, and he looks quite old. He probably participated in the whole case from beginning to end, but he doesn't know that he will be retiring this year and encounter the old case again. What kind of mood would an old forensic doctor repeat.

The old forensic doctor was very professional, with a capable personality, and without much politeness, he took the two of them to the dissection room that integrated storage and autopsy, and then took out two drawers next to each other from a row of refrigerators. cabinet, pointing to the corpse inside, and introduced loudly:

"The previous victim was a full-time housewife, her husband and daughter both had normal jobs, and she was alone at home during the day. The murderer should have knocked on the door, cut off the common artery in her left neck, and died of hemorrhagic shock. All of the knife wounds were repaired after death, and the blade of the murder weapon was about 10 centimeters long, 2.5 centimeters wide, and no more than 0.4 centimeters thick, so it might be a jackknife in terms of specifications."

"It's very convenient to carry, and it won't attract attention." Ai Xiaomei interjected softly.

"Yes." The old forensic doctor nodded, pointed to another corpse and continued, "This one worked as a room attendant in a star-rated hotel, her husband was a worker in a coal power plant, and her son was studying in a university in other places. He was just off the night shift when he was killed. He died. The reason is also the hemorrhage of the arteries, the knife wounds on the body, the distribution characteristics are very consistent with the previous case and the earlier case, each knife is deep to the handle of the knife, there is no overlap with each other, very calm, very cruel."

"Every cut is enjoyment, so he will remember it in his heart." Gu Feifei continued coldly with a serious face.

"Well." The old forensic doctor smiled sadly and said, "In this last case, we found a pubic hair at the scene, which may have fallen off when the murderer was playing with the lower body in front of the corpse at the scene. You also know that pubic hair has follicles Yes, it is very simple to do a DNA test, and the comparison results are indeed in line with the previous case, so my opinion is to join the case.”

Later, in the technical department, Gu Feifei saw the red cloth tied around the victim's neck.

A handsome female technical police officer introduced: "The method of tying the cloth strips is similar to the way women tie silk scarves. It reaches above the chest of the victim, and there are bloodstains on both sides. In addition, the cloth strips are new, but they were disposed of by the murderer." However, there are no fingerprints or other physical clues on it, and the incisions are neat and tight. It should be cut from a large piece of red cloth with scissors. The team is investigating the source of the red cloth, and the knife, we are also looking for a sale There are no clues yet.”

"Looking at it this way, the red cloth was brought to the scene by the murderer, and it is part of the fantasy." Gu Feifei concluded.

"Should... yes. Could it be that he was stimulated when he saw the victim wearing a silk scarf?" The female policeman looked puzzled, and asked herself, "But according to the family members, although the victim wore a silk scarf in winter, I have the habit of wearing a silk scarf, but I have never worn a red one.”

"Imagination is not necessarily aimed at the victim himself. A perverted serial killer is basically an 'empathy' crime. Maybe it's a woman he hates or fantasizes about wearing a red silk scarf!" Tsukuru said deeply, and then looked at Gu Feifei solemnly.

Seeing that the little girl imitated Han Yin's style well, Gu Feifei laughed in her heart, but she still nodded heavily in response, and then asked the female police officer, "Who is the victim of the '98·7·30' case?" Strangled to death by a belt, that belt..."

"Oh, the belt looks like this." The female police officer opened a photo of the evidence on the computer and said, "It belongs to the victim's family, and it has nothing to do with the murderer. Kuling will test it again for you."

"No, I trust your work..."

Almost every city in China has a "People's Road", and this road is often one of the high-end financial and commercial areas of the city, lined with high-rise buildings of various styles, each of which is more dazzling and towering than the other. It seems that only In this way, the prosperity of the city can be reflected.Smelting City is no exception. Han Yin and Du Yingxiong are walking on this wide and straight Renmin Road in the center of Xiangyang District.

Walking on the street in dry and cold weather is really uncomfortable. Du Yingxiong shrank his neck, folded his arms tightly, and put the leather hood on his head, with a helpless expression on his face.Ever since Han Yin said that he was going out for a stroll in the morning, he has been wondering. After walking for a while, he didn't see what Han Yin was going to do, so he finally couldn't hold back anymore. He took the weather as an excuse and tentatively said: "It's March. It's the middle of the month, why is the smelting mine still so cold, I should have brought more clothes. Teacher Han, where are you going, why don't we take a taxi? It can be warmer."

Han Yin, who was walking a little ahead, turned his head to look at himself, then at the leather jacket on Du Yingxiong, smiled gently and said, "We are dressed similarly, why don't I feel cold, you can't bear it." Temper?"

"No...no, no..." Du Yingxiong hurriedly denied, with a flattering smile on his face, and then tentatively said, "I know you brought me here, you must have a purpose, so just tell me?"

"Heh, well. Do you know what are the most appropriate attributes of criminal profiling as an application of psychology? I personally agree with FBI profiling expert Robert Ressler as an art , and art needs subtle intuition and creativity! These two things, the theories in books and the cases I showed you can’t give you, you need the accumulation of real life, experience and practice, which is also common and The difference between excellent criminal profilers." Han Yin didn't solve Du Yingxiong's doubts, but he talked a lot to himself, which seemed to be irrelevant to the case. Of course, this was just a foreshadowing, and then he waved his hands forward He waved, gesturing to look like a road, and said, "Looking at the facts of the case, there are more or less differences in the criminal methods and criminal marks of the first eight cases. The only thing in common is this Renmin Road. Take a closer look. If you look at the azimuth map, you will find that the eight cases are all based on this road as the central axis."

"Oh, then you are going to walk in the footsteps of the murderer?" Du Yingxiong finally got a little enlightened.

Han Yin nodded, and said earnestly: "To be honest, this mining trip is probably the most difficult case we have ever dealt with. I don't know very well. I really need to walk the path of the murderer so that I can see clearly. What the hell does he want?"

"Hehe, I didn't have the nerve to say it just now, but I'm actually a little self-indulgent in my heart," Du Yingxiong laughed at himself naively, "I thought you came here specifically to train me."

"Of course, this is a good learning and training opportunity for both of us." Han Yin said modestly, thought for a while, and then asked, "Then test you, remember the case about Yang Xinhai I showed you?" ?”

"Remember, it was Yang Xinhai who went to the four provinces of Henan, Hebei, Shandong, and Anhui, killing 67 people and raping 23 people!"

"Do you still remember the characteristics of the criminal geographical profile of the case?"

"Well..." Du Yingxiong recalled a little, and said slowly, "He never committed crimes in the city, all the crimes happened in the suburbs, or more remote rural areas, but he would use the stolen money to spend and have fun in the city , it should be because he thinks he is more familiar with the rural environment?"

"Familiarity with the environment is of course one aspect, but in fact there is also a problem of self-confidence." Han Yin explained deeply, "Yang Xinhai was born in poverty, lived in a difficult life, and had relatively poor external conditions. He always had a deep sense of inferiority subconsciously. In fact, he has a typical anti-social personality, which leads him to feel resentment and inferiority towards the city, so the countryside is his psychological comfort zone for committing crimes, while staying in the city, spending extravagantly, and finding escorts are, in his view, a This kind of conquest and revenge." After a pause, Han Yin said back to the topic of the trip: "Let's talk about that case, standing in such a strong urban atmosphere, what did you see?"

Du Yingxiong was silent, looking at the endlessly flowing road. Those well-dressed office workers were all in a hurry. It seemed that under the oppression of the surrounding luxurious giant reinforced concrete buildings, the pace was slower and the clothes were sloppier. The place is out of place. It must have been more than ten or twenty years ago, even if it was not so prosperous, the atmosphere was relatively the same.After contemplating for a moment, Du Yingxiong said: "The murderer has repeatedly committed crimes near Renmin Road for more than [-] years. Confidently blending into the atmosphere here, he must have lived or worked here for a long time..."

"It's just not enough, I think he should be 'born here and raised here'!" Han Yin added emphatically.

"But why did he go to Fuping District to commit crimes again, because the focus of life and work has shifted there?" Du Yingxiong asked.

"Maybe, I can only say that the possibility is relatively high." Han Yin replied ambiguously.

"That...Mr. Han, I have a feeling, don't be angry if you say something wrong." Seeing that Han Yin's words were vague, Du Yingxiong asked hesitantly, "I rarely see you like this, why do you always feel that you are A little careless about the latter two cases?"

"Also—no—yes—la!" Han Yin dragged his voice deliberately, as if to emphasize that there was no preference for one another, "Although the previous case is relatively old, I think it better reflects the personality of the murderer."

"Okay, where do we start now?" Seeing that Han Yin was avoiding the question consciously, Du Yingxiong obediently changed the subject at the right time.

"I saw the crime scene yesterday. Today I mainly observe the environment around the scene to see if I can find out the fixed pattern of the murderer looking for and tracking the target." Han Yin took out a tablet from his backpack, pressed the power button and quickly Then he called up a map of where the crime occurred, "Since all crimes revolve around Renmin Road, if the usual method is followed, it may be related to this road. Let's walk casually on Renmin Road first."

Renmin Road is a north-south main road, from Lantian Road in the south to Yejin Road in the north, with a total length of about 2.5 kilometers. Han Yin and Du Yingxiong walked on this road holding their tablet computers.Every time they come to an area where Renmin Road intersects with the crime scene, the two will stop and investigate carefully: first, they will use measuring tools to mark the precise straight-line distance on the electronic map, and then they will observe the surrounding public facilities and buildings, such as buses. systems, residential areas, governments, enterprises, institutions, or commercial office buildings, etc., trying to determine the intersection of multiple crime areas; at the same time, we consulted the historical data of the smelting and mining area and the external evidence photos of the crime scene in those years. Make some comparisons, so as to avoid the deviation in understanding due to the re-planning of the urban area and the excessive transformation of the surrounding environment.Of course, during this period, the two will also conduct some discussions in combination with the geographical features and the facts of the case...

At this time, standing in front of the original site of the Huichun Hotel again, Du Yingxiong said emotionally: "To be honest, we always say 'a wise man is always worried, but he will make a mistake' or 'there is no perfect crime' or something. In this case, there were a total of ten cases before and after, and the murderer did not make any mistakes, and there were no spoilers or witnesses. Moreover, with the way he committed the crime, it was impossible for his clothes not to be stained with blood, but he was never discovered. I have to say that the whole process of committing the crime was really perfect, and luck is great!"

"There is no need to be so exaggerated, I can only say that the murderer's patience and caution are beyond imagination!" Han Yin smiled and said lightly, "The point you just made is just our intuitive feeling when we see all the case records at once. As long as the murderer establishes a target, he can always succeed easily. However, if you analyze it deeply, you will find that the previous few cases spanned as long as 14 years. Except for the relatively intensive one in 1998, the rest of them took at least a year to appear. , which will definitely dissipate the tense atmosphere in the city, as well as the people's vigilance and attention. Moreover, the murderer's targets will never be the only victims we saw, probably out of caution and committing crimes Conditional constraints and other factors, he has given up far more than ten times or even dozens of times the number of victims. Of course, his luck is indeed too good, especially the case of the power supply bureau and the hotel, no one has paid attention to it Seeing him is indeed a bit unbelievable.”

"That's right, it's amazing, so I think those three cases are of great reference value for determining the identity of the murderer." Du Yingxiong was obviously worried, and when Han Yin mentioned this, he immediately rushed to say, "Just As you said earlier, in the two cases of the power supply bureau, two factors must be met—the murderer can enter the power supply bureau in a familiar and unobtrusive manner, and he must fully grasp the daily routine of the victim and his companions or family members.”

"For example: First, he knew that one of them lived in the room at the end of the corridor on the second floor of the dormitory, and the other lived in Room 414 on the fourth floor of the office building of the Metrology Institute. Then, he knew that the previous victim worked in the cafeteria, which was different from normal work. The work and rest time are different, so I showed up in the dormitory at around two o'clock in the afternoon, and everyone in the surrounding dormitory was at work at that time. The most obvious is the case of the little girl, her mother was on duty at the dispatch center, Dad is out of the meter field, and the time to get home after work is a little later. In addition, the meter building where the little girl lives is mostly office departments, and there are many people at work. At around 6 o'clock in the evening, when the crime was committed, the off-duty people should have finished walking at that time, and the little girl's father was on his way back from work. With such an accurate calculation, he should know more about the little girl's parents and the situation in the building. ?So I think the two cases of the Power Supply Bureau were not stalking, but premeditated."

"I have read the files and know that the metallurgical and mining police have taken fingerprints of all the male employees of the power supply bureau. It seems that internal crimes can be ruled out. However, I also learned that there were more than 2000 employees in the bureau at that time, and men accounted for two-thirds. , such a huge amount of data, it is inevitable that there will be omissions in the collection process. Some leaders and people around the leaders may have special situations. In terms of employees’ family members, people who have business contacts and often go to and from the power supply bureau, as well as power supply In fact, the residents around the bureau cannot be ruled out. In short, I think the murderer must have some kind of connection with the power supply bureau, and I think you almost think so, so Team Liu was asked to provide detailed information about the family building."

Du Yingxiong stopped talking, looked at Han Yin, saw him nodding, and gave a soft "hmm". He didn't know whether he agreed with Du Yingxiong's point of view, or he admired his detailed and in-depth research. Encouraged, he continued confidently: "The murderer of the Huichun Hotel must have had an understanding of the interior of the hotel in advance. We all know that most serial killers are actually penniless guys. Back then, the hotel was good or bad. It is also considered a mid-to-high-end place, and the murderer may not be able to afford it personally, so the insider should be listed as the primary suspect, and then consider the residents at the time and the guests who spent money on the bathing, karaoke and other floors."

"To sum up: the murderer may be a family member of the power supply bureau or a nearby resident, but also works in the Huichun Hotel; or on the contrary, lives near the Huichun Hotel and works in the power supply bureau; or he works in the power supply bureau and occasionally Because the unit is related to the consumption of Huichun Hotel..." Du Yingxiong was talking, and suddenly stopped, and after a moment of deliberation, he concluded, "In fact, I agree with the murderer in my heart. Get into the car quickly, so that it is difficult to be found even if there is a little blood on his body. Therefore, if the scope is narrowed down, I boldly speculate that he may be the driver of the power supply bureau. This is in line with the time when he committed the crime Mostly during the day, and always on weekdays, because the car is his good concealment, and he may need to return the car to the unit on rest days. Oh, I checked. Although the hotel incident happened on a Saturday, it is approaching During the Spring Festival, the country has a unified holiday, and that day is also a working day." Du Yingxiong finally added deliberately.

"That's a good idea. Team Liu can investigate the drivers of the power supply bureau, but I actually have a little disagreement." Han Yin looked relieved, because he really felt that Xiao Du's comeback was indeed much more sophisticated than before, but he I have already had a relatively mature view on the Huichun Hotel case, "Xiao Du, I don't know if you have found out. In the entire case, including the hotel case, there are several cases where the murderer's fingerprints were not extracted. Take a closer look at the case." If you send the time, you will find that they all happened in winter, which means that it is not because the murderer has become smarter, but because the weather is too cold and he needs to keep warm. In this way, the murderer should have come from outside the hotel at that time, as you said The 'identity of the driver' is worth exploring."

Originally, Du Yingxiong was still a little proud of the hearty analysis just now, but he didn't expect Han Yin to almost overthrow his inference with just one tiny detail, and those things are clearly recorded in the file , he never noticed.He really had to admire Han Yin's study of the details of the case, and once again deeply realized that he was still far, far away, so he was stunned for a while.

Seeing that Du Yingxiong was standing still, Han Yin hurriedly explained: "The more you argue, the clearer the truth. It will only benefit the case if you speak out your ideas and discuss it together. Small mistakes are also normal. Discuss like this often!"

"Okay! Okay!" Du Yingxiong came back to his senses, as if he was motivated enough, "Then let me ask the previous question again: If the murderer didn't drive himself to commit the crime, how did he leave the scene calmly? The traces of committing crimes were not found on the body? It should be impossible to take a bus or take a taxi, could it be riding a bicycle?"

"It shouldn't be difficult to do this. He can follow Yang Xinhai's example and choose to walk away from the scene after committing the crime." Han Yin replied.

"Yes, if he really lives near Renmin Road, then his residence is not too far from all the crime scenes, about an hour is enough!" Du Yingxiong suddenly came to his senses, thought for a while, and then asked, "Actually As far as skillful criminal methods are concerned, I originally had an assumption—the murderer has been clean and neat since the beginning of the crime, and has never missed a hand. Does he have a criminal record or military service experience? Especially There are many military enterprises in the mining city, will he hide in those enterprises after retiring or changing jobs, so it is difficult to track down?"

"I don't think so. It can't be ruled out that he committed some other crimes, but he must have never been caught, otherwise the metallurgical police would have connected the evidence over the years. Besides, he doesn't need professional training. I have said many times, never question the talent and ability of a perverted killer to use a murder weapon! Just like the 'BTK killer', his first crime was to kill a family of four without delay..." Han Yin said.

In the afternoon, the situation changed suddenly.

The sky was covered with dark clouds in an instant, and it was raining in an instant, but the small town of Mining and Mining did not feel refreshed because of this. Instead, it cast the shadow of the murder case again.

This time, the murderer fled back to Chaoyang District. The scene of the crime was Room 309, Building 144, Xiangruijiayuan (Cotton Textile Factory Affiliated Court), No. 301 Gongnong Road, Xiangyang District. It was less than one kilometer away from Renmin Road, so he was nearby When Han Yin and Du Yingxiong arrived after receiving the news, Team Liu, Gu Feifei and others were still on the way.

In the wet and cold weather, the room was particularly dull, and the smell of blood became even more pungent.The house faces north-south. A young girl in her 20s lay head-south and toe-to-north in a pool of blood in the middle of the living room. Her neck was cut open, her trousers were stripped to her knees, and a red cloth strip was tied around her neck; a pair of cloth The big bloodshot eyes, trying to open, stared at the ceiling, the eyes were innocent and surprised!

"According to the reporter, the victim's brother-in-law, the victim's name is Liu Yanjie, a 28-year-old worker in a cotton spinning company. The child, the two old people went to take care of the confinement, so the victim lived alone for the time being."

The police from the police station who arrived at the scene earlier walked away after introducing the victim. Han Yin nodded and said hard, then walked around the room, then walked to the corpse, squatted down, and stared at the victim's neck , take a closer look...

Not long after, Team Liu, Gu Feifei, the forensic doctor, Ai Xiaomei and others also arrived.Han Yin looked at Gu Feifei with a flat face, got up and stepped aside, Gu Feifei and the forensic doctor started a series of on-site preliminary examinations.

The cause of death was simple and clear: the large blood vessels in the victim's neck were severed, severe blood loss, spot-like blood spots appeared in both eyes, and the surrounding blood stains were mostly splattered. It was preliminarily judged that a large amount of internal bleeding formed a hematoma, which compressed the trachea and caused suffocation.

In addition, the liver temperature showed that the time of death was around 9:30 in the morning, and there were no scratches on the arms... On-site investigators extracted several fingerprints in the room, which may have been left by the victim and family members from the location. To be compared, other than that, there is no physical evidence about the murderer found...

As soon as Gu Feifei entered the room, she noticed Han Yin's eyes at that time. She followed the eyes and put her gaze on the red cloth strip tied around the victim's neck.After a while she had the answer, she stood up and frowned and said to Han Yin, "The red cloth strips are tied in a different way, that is, two knots are simply crossed."

Han Yin nodded slightly and smiled: "Leave it to Team Liu, let's stop wasting time, it's an imitation crime!"

"Don't, don't, don't! Why did you imitate the crime?" Dui Liu hurriedly grabbed Han Yin and said with surprise, "The modus operandi is very similar, the time period of the crime is similar to the previous one, and the gender and age of the victim It is consistent with the previous years, especially the act of tying the red cloth, which can explain the problem better - in the previous case, the details of the case were kept strictly confidential. The outside world only knew that the murderer had come out to commit crimes again, but they did not know that the red cloth The existence of the article and the difference in the law may be because it was too hasty at the time?"

Han Yin didn't respond in a hurry, looked at Du Yingxiong opposite, took out the tablet from his bag, called up the case record and handed it over, then raised his chin lightly, and said calmly: "What do you think? Tell me! "

Du Yingxiong took the tablet and understood that it was a reminder from Han Yin, so he quickly flicked the screen to look it up, and his brain quickly sorted out his thoughts, and then said: "Suppose this case was also committed by the previous murderer. , then looking at the entire series of cases, there are four cases without fingerprints and physical evidence, namely: the third case of '98·1·13', the fourth case of '98·1·19', the ninth case of this year'1· 20', and the case in front of me. Mr. Han Yin had given me a hint earlier, which may be because they all happened in winter when the temperature was low, and the murderer wore gloves. However, the first three cases all showed obvious signs Behaviors, such as the deliberate positioning of body positions, the exposure of breasts and lower body, the act of stabbing the corpse with additional sharp objects, especially the method of mutilating the corpse, almost ran through the entire case. That is to say, only this case now has no Any fingerprints, physical evidence, and criminal marks..." At this point, Du Yingxiong raised his hand when Liu Dui wanted to refute, and rushed to say, "I know that the red cloth strip you want to mention is also a criminal mark, of course, But you also said that it felt like the red cloth was fastened in a hurry, but in fact it was perfunctory to be precise. He couldn’t understand the meaning of this behavior at all. This is actually a very patient ritual with pleasure in every link... ..."

"Wait..." Liu Dui lowered his head and pondered for a moment, his eyes flickered quickly, and then he raised his head and said, "No, I remember that in the case of the little girl and Huichun Hotel, the murderer never mutilated the body."

"That, that..." Du Yingxiong was momentarily at a loss for words.

"But in those two cases there were corpse rapes, which is probably more intense than the pleasure brought to the murderer by destroying corpses." Seeing that the hero was dumbfounded by Liu Dui's rebuttal, Han Yin said immediately, "You just mentioned The two cases reported by the Ministry of Public Security and the other case of the Power Supply Bureau, from the point of view of criminal markers, were indeed insufficiently enforced. The reason for this is that in the entire series of cases, only these three cases did not occur in the victim's private residence. , but a relatively public area, so it is understandable that the murderer has some scruples... Also, don't you think that the crime time of this case was almost at the same time as the previous case, is it a bit too deliberate?" Han Yin finally I specifically emphasized one sentence.

"Well, I admit that my old ideas can't keep up with the thinking of young people like you, but if it's really imitation, it's easy, and we have to interpret the situation at the scene from a different angle!" Team Liu said himself The concept is always just modesty. How can a person who can take the position of the detachment leader be an idler? After a little advice from Han Yin, he immediately clearly grasped the direction of the next investigation, "There is no trace of breaking the door, and the blood is concentrated. In the middle of the living room, the victim did not resist or restrain himself, indicating that an acquaintance committed the crime, and this "acquaintance" knew the situation of the previous case very well, so he either came from within us, or had contact with the family members of the victim in the previous case. The former It can be ruled out for the time being. Deliberately keeping the time of committing the two cases at the same time seems to be too lacking in anti-investigation awareness. Therefore, the murderer in this case should be hidden in the victim's social interaction. There is an intersection, is that what you mean?"

"Yes!" Han Yin smiled and nodded vigorously to show his approval.

Team Liu regained his carefree look, waved his hand at Gu Feifei and said, "This case is considered particularly bad, but it's far worse than the serial cases we handled. Teacher Han is right, you don't need to waste your energy here." , or sort out the serial cases according to your rhythm as soon as possible, and let me just keep an eye on it!"

"Okay, let's divide the work here, and communicate if there are any problems!" Gu Feifei responded.

The four of them left the scene, got into the car, and did not drive away immediately. Instead, they roughly exchanged ideas about their respective investigations in the morning.After that, Gu Feifei, who was holding the steering wheel, asked what was the next arrangement. Han Yin thought for a while and asked Gu Feifei to put him and Du Yingxiong down on Renmin Road. Ai Xiaomei went back and searched Weibo and blogs, as well as some popular online forums, to see if she could find posts and remarks that paid special attention to the serial rape and murder case in the metallurgical mine recently.

Of course, if there were only the first eight cases, Han Yin would not have contacted the Internet, but now it is different, and the personality of the murderer has changed drastically. ways to communicate with the outside world.If he is really found on the Internet, perhaps the area where he hides or is often active can be directly traced through the IP address. Communication method - the important thing is that he doesn't know who he is communicating with.

Section [-] Letter to the Murderer
Early the next morning, Team Liu received good news that the case of Xiangrui Homeland was solved.

"Consistent with the previous judgment, the murderer is the victim Liu Yanjie's high school classmate and the nephew of Liu Ying, the victim of the '3' case. He has pursued Liu Yanjie for many years but failed, and at the beginning of the year he heard that he was going to marry his new friend The boyfriend got married, but he was so angry that he had the idea of ​​revenge. In addition, after Liu Ying was killed in March this year, he went to comfort Liu Ying's husband, learned some details of the case, and was inspired, so he planned to implement this imitation crime."

"Caught it?"

"Well, this kid may have sensed that the rumors were not right, and he wanted to take the train overnight to escape to other places, but we caught him at the hotel in front of the station. He is also a piece of shit, and he was abandoned halfway before he even joined the team! "

"Then congratulations, you have solved a major case so quickly."

"Where, thanks to those two calls from you, otherwise even solving the case would have taken a lot of trouble!"

When the case was solved, everyone was naturally happy. Han Yin and Liu Dui exchanged some polite words, and then turned the topic to the series of rape and murder cases.

"By the way, have you figured out the relocation of the family building of the power supply bureau?" Han Yin asked.

"I'm just going to tell you this. Most of them choose to add some money and increase the area to relocate, but there are also some who take the money and leave directly. Generally speaking, the situation is more complicated." Team Liu put away his smiling face, brows Wrinkled and said, "I understand your thoughts, you should think that the murderer came from inside the power supply bureau, but you also know that the team has already collected the fingerprints of all the male employees on the job, and the murderer was not found, so you focus on the family members In fact, what you really care about is the background information and current whereabouts of those family members. But this is even more difficult to say. There are more than 300 households in total, and some of them have changed houses and redistributed in the middle, plus private resale and lease. If you don’t have more details It’s too difficult to check the scope.”

"It's okay, this is just one of the directions of investigation, and there are still many possibilities." Han Yin said sincerely, "Don't worry, I will definitely give you a more detailed list of suspects, but it will take a little time. I hope to learn more about this city."

"Then you are busy with your work, it's still the same sentence, just mention it if you need-oh, there is one more thing," Team Liu patted his forehead and said, "As for the driver of the power supply bureau, we also listened to Xiao Du's suggestion and did a detailed investigation. , were all ruled out after the fingerprint collection in the early years."

"This is what I expected." Han Yin smiled, turned his head and just started to take a step, then hurriedly turned back to call Liu Dui, "Liu Dui, wait a moment, Liu Yanjie's case, don't reveal to the media that the murderer has already passed away." As for the news of the case, you vaguely stated that the modus operandi is the same as the previous series of cases, don’t say more about the rest, I have other arrangements.”

"Why?" Liu Dui was stunned for a moment, then waved his hand and said, "Forget it, I won't ask, anyway, just do as you want!"

Although Han Yin's unconventional style of acting always gives people a sense of pretentiousness, but as Team Liu, he can't wait for him to toss hard. In the past, he has handled cases according to the rules for so many years, but in the end it didn't bring anything. As a result, this time, Han Yin was simply allowed to play. The more he can toss, the more capable he is!

One day not long after, at around 10 am, and as Han Yin expected, Ai Xiaomei found a suspicious post on a popular online forum!

This is a post with a very high hit rate, dated January 1 this year, titled "Letter to the Murderer":
"Suspect X", that's what I call you, don't know if you like it or not.In order not to forget your existence, I gave you this name from the beginning.Although I don't know if you are one person, two people, or more people, I have spent a lot of thought so far in order to meet you or meet you.

As a police officer, I feel like a benefactor.Ever since I put on the dark blue police uniform, I have been entrusted with important tasks. I have sent as many as a thousand people to the cell, but so what, you are not on this list.

Once, I didn’t go home for several months, running wildly under the idea of ​​swearing to catch you. Even if I forgot the birthdays of my wife and children, I could still remember all the dates, times and methods of your crimes.I have a colleague who collapsed from overwork and is still paralyzed. Another colleague made a mistake that caused the death of the suspect because of improper interrogation, and I was dismissed because of this.But during this time, you calmly sinned again as if mocking us.

Now, you must be middle-aged, right?With an extremely introverted and asocial personality, are you married?Do you have any children?Have you seen your topic being discussed on the Internet?Will you feel hesitant, or proud?

I went to the places you have been, and the victims even have children as young as 9 years old. Haven't you thought about your brothers and sisters, and your future children?That young and helpless child must be begging you, right?I can't know how you felt at that moment, but as a policeman, I feel extremely humiliated and outraged, and I swear that I will put the handcuffs on your hands with my own hands.But I'm afraid I won't be able to use handcuffs anymore, and as I write this, my police career is over!
But please rest assured, this does not change my original oath, no matter when and where, whether you are a civilian or a policeman, you are always the one I hunt down with my life!Even if one day I regret to leave this world, I will send you a deep curse!
Please make sure not to die before me, we will definitely meet!Right, "Suspect X"?
A retired cop who will track you down to your death

After receiving the news from Ai Xiaomei, Han Yin and Du Yingxiong hurried back to the team from outside.Looking at the printed post in his hand, Han Yin fell into a deep silence.

And Ai Xiaomei thought that she had made a great contribution, so she couldn't hide her excitement, and finally waited until Han Yin had roughly read the post, and immediately said happily: "Mr. Han, look at the date of this post, the murderer committed another crime." Five days ago, is it possible that he was stimulated by this post and committed the crime again?"

"Could it be that the murderer is talking to himself, doesn't he like to be noticed?" Du Yingxiong asked immediately.

"I think what Xiaomei and Yingxiong said is possible, what do you think?" Gu Feifei couldn't help but continued, looking at Han Yin with a questioning look.

Han Yin didn't answer, but still lowered his head, staring at the post thoughtfully, as if he was repeatedly confirming something.After about 5 minutes, he raised his head and said irrelevantly: "Has the IP address been traced?"

"Yes, he didn't hide it on purpose. The IP is registered under the name of a police academy in Lanzhou City, 80 kilometers away from Yekuang City." Ai Xiaomei said in detail with a raised voice, "The forum account is newly applied, and there is no registered identity. Information. He hasn’t logged in for a long time after posting the post, and he reappeared at the end of February, and frequently interacted with netizens as an old policeman. But as far as the current situation is concerned, there is nothing particularly suspicious in the interactive messages.”

"I asked Team Liu, and he also checked. There is no old policeman who retired to teach there at the beginning of the year in the public security system of Mining Mining City." Gu Feifei then added.

Han Yin's expression didn't seem to be surprised. He shook his head, snorted and said, "Hmph, that's because it might be a prank!"

"What?" The people present made surprised voices almost at the same time.

"Have you all heard of the 'Hwaseong Serial Rape and Murder Case' in South Korea?" Han Yin showed a wry smile on his face, "In 2003, when a team leader of the case handling team was about to retire, he wrote a This autobiographical essay on the case begins with a letter like this."

"It's true, just changed a few words!" Before Han Yin finished speaking, Ai Xiaomei tapped the keyboard a few times, and quickly searched for the essay called "Huacheng is not over" in the computer. Then almond eyes widened, and he said angrily, "No wonder the post disappeared after posting. The time in between happened to be a winter vacation, so it must have been posted by a student!"

"I said, the sentence is so awkward, it's not like our Chinese speaking habits. After a long time of arguing, I was played by a brat. I was so excited!" Du Yingxiong said dumbfounded.

"No, not necessarily." Gu Feifei looked at Han Yin with a serious expression, "Maybe the murderer was tricked too?"

"Yes, from the point of view of time and content, this letter may become a catalyst." Han Yin responded positively, "I have been thinking about it before, and I want to find an appropriate comeback for the murderer after more than ten years of cooling down." Reason, then suppose that the murderer entered the low ebb period of his life due to some accident at the beginning of the year. When he was hesitating and conflicting, he accidentally read this online post. The sense of accomplishment may allow him to find a way to escape reality and express himself."

"In other words, he must have logged in to the website. Can we find his IP address from the login cache?" Du Yingxiong asked.

"I'm afraid it's impossible." Ai Xiaomei said with a disappointed face, "This website can be browsed without registration or login, and it has tens of millions of hits. In addition, this post has been reproduced by many hotlinking websites. Now it is difficult for us to confirm which website he saw it from, let alone the specific IP!"

"It's okay, I will let him appear." Han Yin comforted Xiaomei, and then said to Du Yingxiong, "Let Team Liu send someone, you go to the college immediately, find the student who posted the post, and ask him to hand over his account number and password……"

"No need, I'll crack it right away!" Xiaomei said confidently.

"I still have to go there in person, the account number is not the point." Han Yin continued to emphasize to the hero, "You must tell that student again and again to keep him away from this post, and he is not allowed to mention it to anyone, let alone re-register the account Come in and make trouble!"

"You want to..." Gu Feifei seemed to understand Han Yin's intention.

"Yes, as I said before, if the murderer really pays attention to this post, then we can try to establish communication with him!" Han Yin turned to Xiaomei again and said cautiously, "When the hero is done, you log in Account, post a few replies in the tone of a retired old policeman, attribute the case of Xiangrui Homeland to the murderer. Given the murderer's desire to gain attention now, he may not be able to help but deny it. However, you must choose your words carefully and try your best to It should be peaceful and short, just enough to attract the murderer's attention."

"Then Xiaomei, please work harder, keep an eye on this post, and try to trace the IP address as soon as possible if there is a suspicious reply." Gu Feifei urged.

"No problem, don't worry!" Ai Xiaomei assured her with her little pink fist.

Du Yingxiong took the lead and arrived at the Lanzhou Police Academy in about an hour. With the help of the school leaders, he found the student who posted the post without much effort.During the whole conversation between the two, Du Yingxiong kept his eyes stern and his face serious, forming a strong contrast with the students. The scene was indescribably funny.

"Name?"

"Fu Xiaoqi, nicknamed Prince Xiaoqi."

"Where are so many nonsense, what do you say! Age?"

"19."

"Why did you post that?"

"I want to attract everyone's attention and help solve that unsolved case."

"The idea is quite big! Account number?"

"'Yang Chunchun is mine'."

"Who is Yang Chunchun?"

"My goddess!"

"password?"

"950214, my goddess' birthday."

"The account password has been confiscated. From now on, you are not allowed to touch this account and posts again. If we find that you have registered a small account to make trouble, we will not be polite. If you want to become a policeman in the future, you must first know how to be strict. Obey discipline! Do you understand?"

"Remember, I won't even go to that website in the future, okay? You also said that I will also be a policeman in the future, and I will be an insider. Why are you so serious? Brother, can I have some suggestions?"

"Say!"

"I think if you want to solve the smelting case, you should pay attention to the entry and exit records of South Korea and our country after 1988 to see if there is any time point and the crime is about the same time period. I think our case may be similar to that of South Korea. The 'Hwaseong Serial Rape and Murder Case' is the same murderer."

"You've watched too many movies, stop being a policeman and become a screenwriter!"

"Brother, don't you believe me, I'll talk to you carefully... Don't, brother, don't rush away, it's so easy to come here..."

Section [-] Looking at Flowers in the Mist
Late at night, the wind outside was so strong that the windows rattled.It seems to be the same as Han Yin's anxiety and insomnia in the house, and the whole city is in a state of restlessness.

Han Yin doesn't like his current state very much. He has a vague feeling that this case may be beyond his ability to control. The more familiar he is with this city and the deeper his insight into the case, the "image" of the murderer is in his hands. My heart became more and more blurred.He had to admit that when he integrated the murderer's behavior in all cases, he still couldn't capture a complete "image". Changed personality.But such a murderer is easily exposed in reality, and cannot complete the almost perfect crime as presented so far.

Han Yin had no choice but to separate and crush the integrated case features, and analyze them step by step over and over again.

Just like the steps taught by Han Yin in class, let’s first study the victim:

In terms of age, the youngest is 9 years old, the middle is 19 to 29 years old, and the older one is 42 years old and the other is 47 years old.If you only look at the numbers, the span is quite large, then judging from the theory of Han Yin's lectures, the murderer's crime should be aimed at the entire female group.

But this case is special in that it is divided into two major stages of committing the crime, the first is from 1988 to 2002, and the latter is today more than ten years later.

Looking at the group of victims again, Han Yin found that they were mainly in two age groups—young women and middle-aged women.The former concentratedly appeared in the first stage of the murderer's crime, while the latter all appeared in the second stage.Of course, Han Yin also said that when committing crimes against a certain group, the murderer may choose more mature targets as he grows older.But don't forget that the first stage was from 1988 to 2002, and there was a long interval of 14 years. Didn't the murderer grow up?This made Han Yin make a completely opposite judgment from the above. The murderer seems to have two centers of anger, which means that there are likely to be two specific images of revenge.

Looking back to talk about the 9-year-old girl, Han Yin did not ignore her on purpose, but because her existence is meaningless only from the perspective of age group.In many past crimes of retaliation against society or against individuals and groups, children always appeared.For example, Zhao Zhihong, who was dubbed "China's BTK serial killer," and Richard Ramirez, known as the "Night Killer," both murdered 12-year-old and 6-year-old children. The image of always represents vigor and hope, has unlimited potential, destroying them is equivalent to destroying the whole world and the best time of mankind.

To sum up, the contradiction lies in: Is the target of the murderer the entire female group, or a certain individual in this group who has a substitute role?

Let’s take a look at the background information of the victims: the victims in Cases [-] and [-] were unemployed, the victims in Case [-] were students, and most of the others had normal jobs; Except for the two victims in Case [-] and Case [-] (the two did not know each other) who both worked in a metallurgical company, the rest were strangers to each other, had no interest relationship in life, and had absolutely no appearance or stature. The similarities show that they are all low-risk potential victims, and the mission motive can be ruled out, and it is more like a serial crime combining fantasy and sexual desire.

Then, let's dissect the behavioral evidence:
The murderer's motive for committing the crime is to satisfy some kind of fantasy. From the perspective of the crime process, this fantasy is obviously based on uncontrollable anger and sexual repression, and the anger is actually presented in the form of corpse abuse and rape.So in turn, by analyzing the behavioral characteristics of the victim in detail, can we find out the source of the murderer's anger?Prior to this, Han Yin could not avoid a profiling report, which was jointly completed by the case handling team and the expert group of the General Bureau of Criminal Investigation. The profiling content is as follows:
"The murderer is estimated to be born between 1964 and 1971, male, 1.69 meters to 1.75 meters tall, a local or has lived in the local area for a long time, and has the conditions to live alone. This person has relatively serious sexual abnormal psychological or physical defects, especially It has intermittent sexual dysfunction and hates women. Its personality characteristics tend to be introverted, depressed, indifferent, unsociable, withdrawn and out of group, patient in doing things, and highly concealed in doing things."

The key point of this report is that it divides the age range of the murderer and the most fundamental motive for committing the crime, so what does Han Yin think?
Throughout the crime, the act of raping the corpse continued from Case [-] to Case [-]. The forensic medical report of Case [-] did not specify the conclusion of rape, because most of the victim’s genitals were cut off by the murderer, so it cannot be confirmed, but Han Yin believes that the murderer must have done it.Judging from the characteristics of this case, the murderer seems to have a physical defect as mentioned in the profile report above, or to be precise, intermittent sexual dysfunction.Such a judgment is indeed reasonable to a certain extent. The murderer was unable to establish a normal relationship with women due to physical defects, and at the same time was ridiculed and insulted by women, so that his anger and sexual desire could not be suppressed one day, so he used continuous violence. Retaliation and torture against women.

The reason why Case 9 became a watershed for the rape of corpses was because the victim was only [-] years old, her body was not yet fully developed, and her female characteristics were not obvious, which relieved the murderer's psychological pressure on women and awakened him. Sexual desire, and successfully completed the transformation from fantasy to practice, and then his confidence recovered, and he flourished until he stopped committing crimes.Now, after more than ten years, due to pressure or setbacks, his symptoms of physical disorders have reappeared. This may be an important factor for him to commit crimes again without adultery.

In addition, another signature action of the murderer seems to support this analysis:

American FBI behavior analysis experts have summarized and summarized several series of rape cases, and roughly divided rape into four types: power regain type, exploitation type, anger type, and sadism type.The sadistic type can also be called the anger-excited type, and physiological dysfunction is one of its contributing factors. For example, in this case, the victim’s private parts were exposed humiliatingly, and the corpse was stabbed frantically, which is essentially a way to replace the impotent sexual organ insertion .

Now that the fundamental motive for committing the crime is clarified, the corresponding age range is relatively easy to determine.Combining a series of crimes, the murderer has a certain calmness and experience, but also shows considerable impulsiveness.So he should be classified as an adult, and he is not particularly mature.As mentioned in the profile above, it is more appropriate for the murderer to be in the age group of 25 to 30 years old when he first committed the crime. Of course, there will always be some discrepancies, but theoretically the discrepancies will not be very large.

Han Yin first studied the victim, and then solved the motive and age range of the crime with behavioral profiling. Next, he will try to further clarify the personality characteristics of the murderer from the perspective of organizational and social model classification:

Looking at the characteristics of the entire case, the murderer in this case obviously belongs to a mixed type between organized and unorganized.The characteristic lies in the strong organization before and after committing the crime, the plan is very thorough, the action is very cautious, and the behavior of marking is resolute and crazy-the action is quite calm, but the emotion is abnormally excited, and it enters a state of forgetfulness, so that it leaves fingerprints at the crime scene or Semen and other physical evidence.

What kind of person does this type correspond to?It should be said that it may be an antisocial person with a mental disorder, or to be precise, a personality disorder. The paradox is that he can quickly withdraw from a certain personality, and then quickly switch to the opposite personality. That is to say, one second he is still a murderer, and the next second he may be your colleague, neighbor, or even your child or lover, just like the recent "child abuse case of a little girl in an elevator"...

Generally speaking, through this review, Han Yin prefers that the case is aimed at the entire female group, and sex is its main root cause.If this is the case, Han Yin can easily outline a more specific image of the murderer, but there is a big question stuck in his chest-such an analysis is not fundamentally different from the profiling report more than ten years ago. Using this as the scope of investigation back then, the special case team searched almost half of the city. It can be said that everything that should be done was done, so why did the murderer slip through the net?
Compared with the computer, Ai Xiaomei and Du Yingxiong were sleepless all night.

The two stayed in the computer room all night, their eyes were red from the heat, their ears were filled with the roar of the machine running, and their heads were buzzing from the shock.The hero in the middle once proposed to close his eyes for a while in rotation, but the stubborn girl Xiaomei came up again, insisting on sticking to her post, so that the hero was too embarrassed to fall asleep, so he had to drink cup after cup of strong tea to accompany her. .

In the morning, the hero who doesn't use the computer very much can't take it with his eyes, and everything is doubled, so he simply runs outside to get some air.He wandered around the detachment compound for a while, feeling his stomach was empty, thinking that Xiaomei must be hungry too, so he went to a snack bar on the street to buy some breakfast.After returning to the computer room, Xiaomei took the warm soy milk he brought back, sucked a few big mouthfuls, felt her stomach warmed, and felt comfortable all over, and most of the fatigue from staying up all night staring at the computer was relieved. Looking back, I wanted to praise him a few words, but I saw this guy fell asleep sitting on a chair with a deep-fried dough stick in his mouth.

The hero slept like this for four or five hours. When he opened his eyes, he thought he had just dozed off at first, but when he saw the electronic clock hanging on the wall, he realized that it was past 11 in the morning. Mei said something, but saw that she looked nervous and was typing on the keyboard quickly, as if she had discovered something.

"You're awake, come and take a look, and found something suspicious!" Hearing the movement of the hero getting up, Xiaomei hurriedly called him to the computer, pointing to the monitor screen and said.

"Really? Let me see." The hero quickly moved forward, followed Xiaomei's finger, and saw a reply with no words, only a long series of numbers and letters, "1247.5YT/5128." The hero read out the reply Reply, with some doubts, "The post written in this way is a bit suspicious."

"I just checked the server, the user name was registered almost 5 minutes ago, and then I sent this inexplicable message, and then I went offline immediately, and I used a mobile phone, who else could it be if it wasn't the murderer?" Ai Xiaomi said in a positive tone.

"Then what does that mean? What does he want to say?" Du Yingxiong asked in wonder.

"Don't worry about this," Ai Xiaomei waved her hand, "I found the IP address, and it's registered at No. 69, Qianjin Road, Xiangyang District."

"Then I'll notify Team Liu and ask him to send someone to investigate immediately." Du Yingxiong said while taking out his mobile phone.

Du Yingxiong dialed Liu Dui's phone and pressed the speakerphone. There was a lot of noise on the other end of the phone. He had to raise the volume and shouted so that Liu Dui could understand what he said.Team Liu also yelled over there: "What? No. 69, Qianjin Road, Xiangyang District? It's the address of the newly completed gymnasium. I'm here now! To celebrate the official opening of the gymnasium, the city took the lead in organizing a The city leaders attended the friendly basketball match between us and our brother cities, and I was performing security duties.”

"Damn, it's too cunning." Ai Xiaomei gritted her teeth and couldn't help swearing, "It must be that the gymnasium has temporarily turned on the Wi-Fi network for reporters to use for free in order to facilitate the media's interviews and submissions. Used by this guy."

"Is the game over? Hurry up and block the gate!" Du Yingxiong asked on the phone.

"Yeah, it's just finished, there are thousands of people, more than half of them have left, how can we check?" Team Liu replied helplessly on the other end of the phone.

"Forget it, he may not be in the gymnasium. It is estimated that he can almost receive the network signal outside the gymnasium. Then you can bring back all the surveillance videos that can be collected in the gymnasium and outside the gymnasium." Ai Xiaomei Said a little dejectedly.

"Okay, that's the only way to go, this kid is really difficult to deal with!" Team Liu said with difficulty hiding his disappointment.

Not long after hanging up Team Liu's call, Han Yin and Gu Feifei arrived after hearing the news. Several people studied the string of numbers "1247.5YT/5128" for a long time, and didn't even eat lunch. What Morse? Telegraph codes, telegraph codes, and so on, were all discussed and then ruled out one after another, but nothing came out anyway.Team Liu also joined the discussion after he came back with the surveillance video data. He thought it might be the file number of a case that the team had handled, but it turned out not to be the case, but it can be confirmed that this should be the murderer using his own way of conveying information.

There is no way for so many people to get stuck on this problem, so Gu Feifei entrusted the task of solving the puzzle to Ai Xiaomei and Du Yingxiong, and at the same time asked them to go through the surveillance video brought back by Team Liu to see if they could find the whereabouts suspicious person.Team Liu interjected and asked Han Yin and Gu Feifei what they were going to do next, and Han Yin spat out the words "take the bus".

Everyone else went to work on their own, and there were only two little guys left in the computer room. The hero suggested that Xiaomei search the Internet, maybe he could find clues about the string of numbers, and he watched the surveillance on another computer. material.Of course, Xiaomei raised her hands in agreement, not because watching the video was boring, but because she didn't dare to say it in front of so many people just now, she felt as if she had seen a similar set of numbers somewhere before, but she couldn't remember it at the moment.

After the division of labor, the hero began to focus on the monitor screen, while Xiaomei began to tap the keyboard.After about two hours, both of them stopped what they were doing, looked at each other in unison, and then shook their heads in disappointment.At this moment, Xiaomei's cell phone rang, and she went out of the computer room to answer the call.

After five or six minutes, Ai Xiaomei walked in happily, shaking the phone and smiling, "It's a call from a college classmate..."

Before Ai Xiaomei could finish speaking, the hero stopped the conversation with a little jealousy: "Look at this emotion, is it your first love boyfriend?"

"Go away, I haven't finished yet." Sitting back in front of the computer, Ai Xiaomei continued emotionally, "I was notified to attend his wedding banquet next week, oh, it's too unexpected, our class He will be the first to get married! At that time... well, I thought of it, maybe this is..."

"What is it?" The hero asked anxiously, sliding the chair and leaning over.

"The classmate I mentioned just now was from a very poor family when he was studying. He continued to work and study until he graduated. He had to work several jobs a day and worked as an administrator in the school library for a while. Once he fell ill, I also helped him with one day's shift." Ai Xiaomei took a closer look at the suspicious reply, recalled a little and explained, "I think this string of numbers might have been like this: 'I247.5YT/5128', the first A character should be a capital I in English, not the number 1. I don’t know if the murderer misread it or wrote it wrong. I think what he originally wanted to write was the call number of a library. Usually our national library Both use the CLC: 'I' means 'Literature'; '24' means 'Fiction' within this category; '7' means 'Contemporary works from 1949 to the present'; '5' Means 'new style novel or novella'; followed by the two letters 'YT', if you guess correctly, it should be the abbreviation of 'Yetu', which is the pinyin abbreviation of 'Yekuang City Library'; and then The number is probably the specific serial number of the book!"

"Oh, to put it bluntly, it is the loan number of a novel. Can I find out which novel it corresponds to from the Internet?" Hero asked anxiously.

"Most libraries have websites that support online inquiries." Xiaomei fiddled with the computer a few more times, then slowly shook her head and said, "There are websites, but they have been upgraded and maintained since three days ago, and they cannot be used normally."

"Then what are you waiting for?" The hero looked up at the electronic clock, "It's not time to get off work, let's go to the library quickly, maybe he has some clues in that book."

The two raced for time and didn't bother to notify Team Liu. They stopped a taxi when they left the gate of the detachment and went straight to the city library.

After about 20 minutes, the taxi stopped in front of a majestic beige building, and the two got out of the car and stepped on several blue-gray marble steps, and walked into the library hall.

Xiaomei stopped at the entrance of the hall for a while and looked around, while the hero went straight to the service desk directly opposite, but before he walked a few steps, he heard Xiaomei calling him softly behind him.The hero turned around and saw Xiaomei standing in front of the large floor-to-ceiling glass window five or six meters away on the left hand side of the gate, surrounded by a row of inquiry machines for bookstores and libraries.

When the hero came over, Xiaomei had already entered "I247.5YT/5128" in the query bar on the touch screen, that is, Xiaomei changed 1 to I such a string of numbers.Sure enough, as she expected, it was a call number, corresponding to a novel called "Flowers Are Not Flowers, Mist Is Not Mist".In-depth inquiries show that this book was put into storage in 2002 and is still in circulation, which means it has not been lent out at this time.

"Let's go, since it's confirmed, let's hurry up and find the book." Xiaomei urged.

"I don't think it's necessary." The hero frowned, with a wry smile on his face, and sighed, "'Flowers are not flowers, they are not fogs,' they are nothing. Probably the murderer just wanted to use the title of the book to respond to the so-called old Police, explain that the case of Xiangrui Homeland was not done by him!"

"Ah, this pervert, tossing and tossing, just to pass on such a thing? Then why don't you just say it online?" Xiaomei said sullenly.

"You also said that he is perverted, how could he think the same as normal people?" Hero said angrily, "He hides in the dark, tests and teases us policemen wantonly, how refreshing it is for him what?!"

"Then I go to the computer room of the library to check the borrowing records and search records? Just in case, why don't you look for that book?" Xiaomei suggested out of caution.

"With the murderer's usual caution, I guess he didn't borrow this book. He probably just searched for it randomly on the inquiry machine, as long as the title of the book can express the meaning he wants to convey. But it's good to confirm, I will find the book , you should focus on checking the time of the book search..." The hero paused, looked up and looked around the ceiling, and said disappointedly, "There is no surveillance near the door, so we can only wait for the time to be confirmed, and then ask the people in the library if there is any Didn't notice the book searcher."

"Okay, but you should ask the administrator to help you." Xiaomei grabbed the hero who was about to go to the borrowing area, then turned to the service desk, and explained expertly as she walked, "Books are borrowed and borrowed every day. If it is always placed in a fixed place, the administrator will not be exhausted? Just like the books in the I247.5 category, the borrowing rate is usually high. In order to save time and labor intensity, after receiving and returning the books, the management The staff should just re-shelf according to the general category, there may be several bookshelves in this category alone, and you can put the returned books in any one, if you only rely on you to find them, you don’t know when you will find them!”

"Ah, let the administrator help me!" the hero said in surprise, rubbing his forehead.

It wasn't until evening that Yingxiong and Xiaomei returned to the team. At that time, Han Yin and Gu Feifei also just came back from the outside.Team Liu was more thoughtful. He had already prepared dinner in the cafeteria and told them to go back to the hotel after eating.

During the meal, Xiaomei and Hero reported on a series of activities in the afternoon.

"Flowers Are Not Flowers, Fog Are Not Fog" is a suspense novel written by a famous female writer in China. The hero found this book with the help of the administrator. There is indeed nothing in it, and there are no specially marked words. The killer should just borrow its name.Xiaomei found the borrowing and search records on the server in the computer room of the library. In addition to the one she searched for, there was also a search record shortly after the library opened, which was probably done by the murderer.Xiaomei and Hero asked the library administrators, cleaners, and security guards one after another, but they didn't have any impression of the searcher.As for the list of all borrowers of this book, Xiaomei also printed a copy and brought it back to the team.

However, after listening to the reports from Xiaomei and Hero, Han Yin, Gu Feifei and Team Liu all felt that the investigation was of little value, but judging from the performance of the murderer who racked his brains and made troubles this time, it can be felt that he has a strong sense of responsibility for the crime. This deep obsession and devotion shows that the transformation of his personality is becoming more and more obvious and in-depth. I am afraid that he will do more things beyond imagination in the future.

In addition, so far, Han Yin's idea has basically become a reality. He has indeed caught clues about the murderer through the Internet, and has also established a secret communication method with him, and he has indeed taken the bait.But when everyone asked Han Yin how to make more articles in the post, they heard an unexpected answer: "Xiaomei, you don't care about the post, and leave it to the Internet police to monitor. If the murderer logs into the account again and actively It’s best to reply, otherwise we don’t take any further actions, so as not to anger the murderer. I’m worried that if he doesn’t get a response to his ‘wen kao’, he will turn to violent means to prove his innocence in that case.”

Section [-] Geographical Profile
After several days of on-the-spot investigation, this afternoon, Han Yin, who had been wandering outside seemingly carelessly, felt that it was time to take out the profiling of criminal geography and exchange opinions with the case handling team.Of course, this result had been discussed previously within the support group and was unanimously agreed upon.Han Yin and Gu Feifei intended to train the two little guys, so Du Yingxiong was the main reporter, and Ai Xiaomei assisted.

Criminal police detachment small conference room.

Du Yingxiong stood in front of the projection screen with a serious expression, and Liu Dui led several backbone case investigators and the rest of the support team to sit on both sides of the long conference table.Ai Xiaomi called up a detailed crime location map on the laptop and displayed it on the projection screen, and then Du Yingxiong began to explain calmly:

"This series of crimes is generally divided into two major stages. Geographically, it just spans the two districts of the city. Our analysis focuses on the crime stage from 1988 to 2002, because the murderer committed crimes in this stage. The geographical distribution characteristics of the murderer are more instructive to profile the background information of the murderer."

"Through the orientation map behind me, you can clearly see that the first eight crimes were actually carried out on Renmin Road in Chaoyang District. Among them, cases 20, 150, 700, 1, and cases 50 and [-], They happened on the east and west sides of Renmin Road respectively. The former incident occurred at a straight-line distance of [-] meters to [-] meters from Renmin Road, while the latter was at a distance of [-] meters to [-] kilometer. Cases [-] and [-] occurred between the southern end of Renmin Road and Shuichuan Road at the junction of the two, the place where the crime occurred was no more than [-] meters away from the junction. This clearly shows that the surrounding area of ​​Renmin Road is the murderer's psychological comfort zone, and it can also be seen that he has a high degree of respect for this area with complex terrain. In addition, we believe that the prosperous and high-end regional characteristics of Renmin Road will create a certain degree of psychological oppression for outsiders and those in distress. Therefore, judging from the murderer’s steady crimes and his ability to come and go, he should be Renmin Road. The surrounding 'seated households'."

Du Yingxiong entered the state quickly, and the first argument was clearly stated.He paused for a while, then nodded slightly to Xiaomei, and Xiaomei immediately operated the keyboard cooperatively, and two similarly detailed azimuth maps appeared on the projection screen.

Du Yingxiong pointed to the two pictures side by side behind him, and then said: "Then, can we find a fixed pattern for the murderer to choose the victim from the geographical distribution characteristics of the crime just introduced? The answer is - yes!"

"Behind me are two maps of bus routes passing around Renmin Road, which are the downlink routes of No. 9 and No. 3 buses. You can see that we have made special signs on the key points."

"Let's talk about the No. 9 bus first: it starts from the copper processing plant of the metallurgical company in the northwest of Renmin Road. Soon after entering the section of Renmin Road, turn left at the first fork with traffic lights to the intersection with it. Silong Road, and after a large circle in the east of Renmin Road, it merges into Renmin Road again through the roundabout of Yekuang Bus Station, and finally enters the terminus of Shuichuan Road. This line covers the crime scenes of Cases 200 to [-] Among them, the closest one is only a dozen meters away from the station, and the farthest one is no more than [-] meters away.”

"Let's talk about the 3rd road: it starts from the lead-zinc processing plant of the metallurgical company in the northeast of Renmin Road, but it first passes through Silong Road, and then turns left at the same fork mentioned above to enter Renmin Road. Then it is completely along Renmin Road, passing through the roundabout of Yekuang Bus Station, passing through the junction, and also entering the terminal of Shuichuan Road. It covers the crime scene directions of Cases [-], [-], [-], [-], [-], and [-]. It is very close to the corresponding stations.”

"Combining the above two bus lines, it can cover all crime scene locations, so is this a way for the murderer to choose the target? The murderer may have encountered a 'favorite' target while traveling on the bus, and then tracked it and committed the crime on the same day , or commit crimes after repeated follow-up in the future.”

"To be more specific, let's look at several overlapping sections and stations of the above two bus lines: the terminus of Shuichuan Road; and then they all have stops near the roundabout of Yekuang Bus Station, and they are not far from each other ; Then there is Silong Road. Although the driving directions are different, they overlap each other by about 1 kilometer on this road. If, as judged above, the murderer selected targets on the two bus lines of No. 3 and No. 9, then Their overlap is very meaningful. Of course, considering the circumstances of the case, the latter two overlapping areas are obviously more valuable for analysis, because they also mean that the life trajectory of the murderer overlaps."

"Let's make an in-depth analysis: First of all, let's talk about the overlap of the bus stops near the roundabout of the Smelting and Mining Bus Station. It’s still your case handling team who believe that the murderer is very knowledgeable about the power supply bureau, and may have a direct or indirect relationship with the power supply bureau. Speaking of which, I think Team Liu and everyone here should have experienced the large-scale fingerprint extraction competition back then. As for the work, unfortunately, the final result is that the direct relationship between the murderer and the employees of the power supply bureau was ruled out, thus giving up the investigation direction of the power supply bureau. But now, when we make it clear that the No. 3 or No. 9 bus is used as the The way the media finds targets, when we suddenly find that they all have a station near the power supply bureau, and then examine the characteristics of the two cases of the power supply bureau, we have to admit that if the murderer has no direct relationship with the power supply bureau, there is likely to be a The indirect relationship may be the family members of the employees of the power supply bureau, or people who live nearby and can deal with the power supply bureau.

"If there may be some unexpected situation in the previous analysis, then the analysis of the overlapping section of the two buses on Silong Road will make us very sure that the murderer must belong to the smelting company or an employee of the smelting company system..."

When Du Yingxiong said this, there was a rare noise in the meeting room. It seemed that some police officers from the case handling team wanted to refute his point of view, but Liu Dui stopped him with his eyes in time. Du Yingxiong continued: "This case The murderer, we think he is a mixed type between organized and unorganized. The characteristics of the crime usually develop from near to far in terms of distance. This is not only the geographical distance, but also the psychological distance. For the first time committing a crime, he either chooses a familiar geographic location or a familiar target. Of course, the latter kind of familiarity does not mean a real relationship in reality, but a degree of familiarity established through indirect means, such as the murderer We often encounter the victim in the car. For example, he heard her background information from a worker, but we are sure that they have no direct mutual interests. At most, it is a relationship of nodding and greeting each other. So, we can't help but ask, first of all The fact that the victim of the case worked at the General Factory of the Smelting and Mining Company, does it mean that the murderer is also like this?"

"The argument just now is just one, then the second: As mentioned earlier, the murderer committed the crime around the east, west, and south directions of Renmin Road, but not in the north direction, and the demarcation point is the first street on Renmin Road. A fork in the road with traffic lights, that is to say, all the crimes occurred in the south of Silong Road. Why is this? It is because the general factory of the Metallurgical and Mining Company is just 200 meters away from the north of Silong Road. On the friendly road. There is no need to explain it? This is almost a very instinctive desire to keep a psychologically safe area in an area he is familiar with and often moves around. This shows that the murderer is very worried that the police will link the case with the mining company. connect together."

"Thirdly, most of the previous crimes occurred around five or six o'clock in the evening, which coincided with the off-duty time of most people, and they were connected to two sites that were also located near the Silong Road Smelting and Mining Company. The bus routes that can cover all the locations of the crime scene, as well as the roughly clear method of finding the victim using the bus as the medium, should be able to draw a more specific and reasonable inference-the murderer came from the General Factory of the Metallurgical Mining Company. After work, I met the victim and committed a crime when I took the bus back to the Power Supply Bureau! This is why I have always emphasized that the bus line is a downward line. As for the latter cases, some occurred in the morning or afternoon, maybe It is because the murderer actually works in three shifts. Let me explain in more detail: the murderer may have encountered Cases 3, 9, and [-] while taking the No. [-] bus after work, and lived along Renmin Road or in the east direction respectively. and the victim at work; while taking the No. [-] bus, he completed the implementation of cases [-], [-], and [-]. This pattern of crimes can also be proved once again that the murderer has a strong organizational ability. Although it was at least one year later, he never The crimes were not committed consecutively on a certain bus line. From this, we can also draw an inference that although the above-mentioned victims are all of the accidental type, the murderer’s crimes are by no means random. In addition, Cases [-] and [-] that are not mentioned should be There is no connection with the bus, and given that he may have an indirect relationship with the power supply bureau, we believe that the two cases are completely premeditated crimes!"

"As for the two cases this year, the murderer expanded the crime area to Fuping District, probably because his focus of life or work shifted there. We can try to investigate this direction."

Finally, when the hero finished his concluding speech, the key members of the case handling team who had been sitting down holding back their anger, didn't care about Team Liu's face at this time, and immediately turned to the hero, Han Yin and others Yelling: "Aren't you too self-righteous? Do you think we haven't thoroughly investigated the smelting and mining company?"

"That's right! That's right! We've gone through the general plant of the Smelting and Mining Company, and even the entire system of the Smelting and Mining Company. You mean that we didn't do our work meticulously enough, so we let the murderer slip through?"

"We have focused on the investigation of the power supply bureau and the smelting and mining company. Why do you only approve the previous investigation and deny the latter investigation?"

……

"Okay, you guys, what are you arguing about? If you have different opinions, it's up to you, but pay attention to your attitude!"

Someone took the lead in choking, and the people behind followed suit. Although Team Liu reluctantly came out to smooth things over, it also made people feel a little reluctant.The atmosphere in the conference room was very awkward. Fortunately, the support team had seen this kind of scene a lot, and they did not show any particularly antagonistic emotions. Gu Feifei glanced at Han Yin with a wry smile, and Han Yin calmly said: "We I don't intend to obliterate your labor, and I don't feel that you are ineffective in handling the case. I just report the results of our analysis. Later, we will continue to make corrections according to the situation, and then we will make a more comprehensive criminal psychology based on this. Profile. Of course, I admit that I am still a little bit troubled..."

Before Han Yin finished speaking, he saw Team Liu's mobile phone on the table vibrate suddenly, so he stopped talking and nodded to Team Liu to let him answer the phone first.Unexpectedly, Team Liu put the phone to his ear for a while, and his expression changed drastically. He quickly glanced at the screen of the phone, and then hurriedly said a fixed phone number to the policeman next to him, and told him to find the technical department immediately to find out the owner of the phone. address.

Looking back, facing Han Yin and the others, Liu Dui frowned and said unexpectedly: "Yes, it's the murderer. He said on the phone: 'Since you are not smart enough, I will call you to inform you. I didn't do the case. If you want to know what I like, come and see!'”

"How could he have your mobile phone number?" Everyone asked in surprise.

"It's nothing unusual." Team Liu explained with a dejected expression, "When I was handling the case in the early years, I was not a detachment leader. I don't know how many police and civilian contact cards with mobile phone numbers were issued during the investigation. In changing the number, I was actually looking forward to receiving a valuable tip one day, but I didn't expect it to be a mocking call from the murderer."

Section [-] Kill Proof

This is an unconventional case - after the murderer committed the crime, he used the victim's home phone to get through the mobile phone of the criminal police responsible for the series of cases to report the case in person, so when the police quickly registered the address through the phone, they found the address at No. 196, Jinhua Road, Fuping District. When looking at the crime scene in Unit 3, what I saw was a blood-stained room and the dead who was almost quartered by five horses.

The crime scene centered around the living room of the house, which is commonly known as the luminary, that is, the living room with windows.Once in, the windows were covered with curtains, and after Han Yin pulled them open, a ray of setting sun came in leisurely, and the living room suddenly became more blood-red—the floor, the wall, the sofa, the decorative cabinet, the curtains , wait, all of them were smeared red with blood.As in the previous two cases, the victim was a middle-aged woman. The ID card found in her home showed that her name was Liu Hongyan. Her clothes were torn into pieces and scattered around. Lying next to the glass coffee table, to be more precise, it is just a torso with head attached lying in a pool of blood, red cloth strips are tied around the neck, limbs have been chopped off and randomly thrown on both sides, the upper body has been cut open, heart and lungs and other internal organs The organs were cut off and placed on the coffee table, the large intestine was torn into several sections, some were thrown on the sofa, and some were hung on the TV...

"The murderer deliberately arranged the scene so bloody, presumably on purpose to let us see his abilities. Maybe it is really not a wise choice to contact him through the Internet." The previous worries seem to have been confirmed, Han Yin's tone Some remorse.

"You mean he has such a strong desire to show off because of our 'teasing' on the Internet?" Captain Liu asked, grinning and looking around.

"Not necessarily, I think he is more like being irritated by the victim!" Gu Feifei answered the words and denied, then poked the victim's head back deliberately, exposing the knife wound on the neck and explained, "Look, this The knife wound was very shallow and did not cut off the artery, and there were no dragged bloodstains in the whole scene, but there were many dripping bloodstains, especially in the distance from the door to the coffee table. I just measured a little, and the diameter of the blood droplets is roughly the same , indicating that the bleeding point of the deceased was at least 1.2 meters above the ground. It was obvious that the murderer's knife from the back did not result in a fatal blow, so the victim fled from the door to the window of the living room in a panic, wanting to ask for help... ..."

Listening to Gu Feifei's words, Team Liu took another look at the victim, and interjected, "She is relatively fat, with a thick and short neck. The murderer may not have grasped the position and strength well."

"That's right!" Gu Feifei stood up and said while gesturing, "The victim's head was obviously hit by a blunt instrument continuously, and her legs and knees were severely bruised. It is estimated that when she ran to the window to escape, Accidentally tripped over the coffee table, the murderer caught up later, and the two began to fight. During the process, the murderer may have picked up something around him and repeatedly slammed on the head of the deceased, so we can see many parts of the scene The blood was deliberately wiped on by the murderer to vent his anger, but the ceiling and curtains above the deceased's head were stained with blood in the form of medium-speed splashes, which should be caused by the murderer vigorously wielding a blunt weapon."

"The murderer missed the first blow, which caused the entire crime process to lose control, and he felt a strong sense of frustration, which inspired even more crazy corpse-mutilation actions." Han Yin continued, "In this way, the murderer They are very sensitive to the experience of frustration, and should belong to the lower social class in reality."

At 8 o'clock in the evening, Gu Feifei went into battle in person and completed the autopsy.

When Han Yin and others entered the dissecting room, the deceased placed on the dissecting table had been pieced together, the blood all over his body had been cleaned up, and his hair had been shaved.

"It is completely consistent with the previous judgment. The victim died of craniocerebral injury caused by blunt force on the head. The time of death was roughly half an hour to an hour before Team Liu received the call." Gu Feifei pointed to the top of the victim's head Said, "There is a depressed fracture here, the more common shape is round, conical or almost round, but what you see now is angular. From the outline, the contact surface of the head and the blunt instrument should be It is rectangular, six to seven centimeters in length, and nearly two centimeters in width. In addition, when the hair was just shaved, several pieces of black engineering plastic were found in the victim's hair..."

"Engineering plastic fragments? Could it be the back cover of the mobile phone? Could it be that the murder weapon is that kind of large and wide-screen mobile phone?" Ai Xiaomei couldn't hold back for a while and interjected.

"No." Before Gu Feifei could speak, the hero said contemptuously, "Didn't you hear that Gu Jie said that the width is about two centimeters? Where can there be such a thick widescreen mobile phone?"

"The hero is right. Unlike mobile phones, this kind of engineering plastic is used in the casings of many electronic products, small appliances, and even office supplies. Mobile phones are relatively light, so it is difficult to exert such a large force." Gu Feifei continued.

"W-Would that be..." Xiaomei seemed very unconvinced, she thought hard and said, "Could it be something like a tablet computer or an MP4 player? There are many such domestic machines on the market, and they all do it well." It's thick and heavy."

"Oh, it's possible." Gu Feifei turned to Xiaomei and nodded again, "In short, if we can confirm the type of murder weapon, it should be helpful to identify the murderer!"

Several people were discussing who the murder weapon belonged to. Liu Dui stepped in quietly, walked straight to Gu Feifei, and said softly, "The victim's daughter is here, and she wants to see the mother's body."

"She can watch it if she wants, it's her right." Gu Feifei said somewhat helplessly.

Since Gu Feifei had no objection, Team Liu waved towards the door, and then a tearful young girl walked in with the support of a policewoman.

"Are you sure you want to see it?" Gu Feifei said gently and pitifully, holding both ends of the white cloth that had just been covered with the corpse.As a forensic doctor, she has seen so many cases of being so broken by this moment that the trauma of the soul cannot be erased many years later.

"Yes, I want to see what my mother looks like now." The girl murmured for a while, pushing away the policewoman beside her, as if mustering up a lot of courage.

"Okay." Following the girl's response, Gu Feifei slowly lifted the white cloth, and the image of her mother with a bald head covered in scars and a white face appeared in front of her daughter.

The girl was not as excited as she had imagined, she stared straight at her mother's miserable face, twisted her clothes back and forth vigorously with both hands, and tears fell silently.

This situation, every second, is a torment for the police officers present, not only sympathy and grief, but also guilt, especially Han Yin-despite the crazy behavior released by the murderer at the crime scene, He was more angry at the victim's fierce resistance, but when he really calmed down and thought about it objectively, Han Yin had to admit that a considerable part of the murderer's starting point for committing the crime was mocking the police's insight. Team Liu's phone call is the best proof; of course, the more important thing is to show his own strength.

If there hadn't been a secret battle in the online posts, he might not have made such a quick move; this time he almost missed, which was obviously related to the hasty selection of the victim. This should be like what I said just now, he was too eager to prove and show himself!If he could be delayed a few days, or even a day late, theoretically there is a possibility of being arrested, then there would not be such a corpse on the dissecting table at this moment.In this way, Han Yin always feels that he bears the unshirkable responsibility for the current situation, and he regrets the choice of the previous investigation direction.

The atmosphere in the dissecting room is suffocating, so we can only end it quickly.Gu Feifei ignored the girl's repeated request to stay a little longer, put the white cloth back on the face of the deceased, and asked the policewoman to take the girl to the office next door.Her move was not just to divert the girl's attention, but to hope that she could help identify the murder weapon that killed her mother.

In the medical examiner's office, seeing the girl take a few sips of hot water poured by the policewoman and her mood eased a bit, Gu Feifei asked straight to the point: "Judging from the fracture on your mother's head, the length of the murder weapon is about six or seven centimeters." , with a thickness of about two centimeters, and the outer material is black engineering plastic, similar to the TV remote control or the back shell of a mobile phone that we often see. In addition, it should have a certain weight. I wonder if you have such a thing in your home? Especially Near the coffee table in the living room."

"No, definitely not! I used to have a radio of about the same size, but I gave it to my grandma a few days ago." Without thinking, the girl changed the topic, "But your people just brought me home to verify the financial and other losses. At that time, I found that the 1 yuan that my mother had just withdrawn from the bank in the afternoon was gone!"

"Would you have put it somewhere else and you didn't find it?" Han Yin asked suddenly and hastily.

"Impossible, the money is like this," the girl shook her head and said, "I have a very good colleague who is short on money to buy a house recently, and I want to borrow some money for renovations. My salary is not high and I don't have much savings. Two days ago, my mother said that a passbook was due, so she asked her to withdraw 1 yuan to give to a colleague for emergency. I also told her not to misplace it. Anyway, there is not much money, just put it on the TV cabinet. As a result, I I just searched several places at home but couldn't find it."

"Are you sure she has withdrawn the money?" For some reason, Han Yin was particularly cautious about losing money.

"That's right, she made a phone call to me after withdrawing the money in the afternoon. It is estimated that the murderer was after my mother at the bank." The girl said with hatred.

"Oh..." Han Yin responded softly, then fell into deep thought.

"Are you sure you don't have anything of the specification I mentioned at home? It might be small appliances or digital products, or it might be decorations or something." This time it was Gu Feifei's turn to ask.

"This...really not." Although the girl thought about it carefully, the answer was the same as before.

"From this point of view, the murder weapon should belong to the murderer, and it may be something he carried with him." Gu Feifei's eyes were slightly bright, "I often carry it with me, and it has some weight. What could it be?"

……

It was almost 10 o'clock in the evening to send Liu Dui and the victim's family members away. Several people helped Gu Feifei finish the finishing work and returned to the hotel.But shortly afterwards, Han Yin returned to the forensic department for some reason, and after a brief negotiation with the on-duty forensic doctor, he went into the dissection room alone.

In the dissecting room at midnight, the solitary lamp was dark, and the silence was deep, and the air became even colder due to the presence of the refrigerator.Han Yin walked slowly towards the wall, unimaginably opened three large refrigerated drawers one after another, and the last three victims of this series of cases came into view one after another.Not just these three, they are all here at the moment, all 11 victims, all appear in Han Yin's mind, in the flashing picture, they are all covered with pale shrouds, lying quietly on the dissecting table .

Han Yin was silent for a moment, stepped back a few steps, raised his hips slightly, and sat on an anatomy table behind him.He caressed the countertop with both hands, as if feeling the breath of the corpse that had been lying on it.He stared at the distance indifferently and blankly, and in his mind he followed the order of the crimes to uncover the corpses covering the faces of the victims one by one, and the victims seemed to have opened their eyes at once, looking at Han mournfully. Yin, telling the stories behind their murders—on this night, Han Yin made a crime profile report that was almost subversive!

Section [-] Criminal Profile
"We were all wrong! From the beginning until now!"

This is Han Yin's opening remarks at the profiling analysis meeting.I can imagine the reaction of the police officers of the local case handling team here. They immediately made expressions of surprise, astonishment, disdain, contempt, or anger, so various emotions were mixed together, and there was inevitably a movement in the conference room A lot of noise.

With the previous experience in the geographical profiling meeting, Han Yin, who stood alone at the front of the conference room, seemed to be psychologically prepared. Facing the scene of whispering, pointing, and turmoil in front of him, he always looked calm, He didn't rush to explain, but looked at everyone silently with a peaceful and slightly stern gaze.

After a while, Han Yin's silent composure and determination gradually infected the people below. The emotions in the conference room gradually became more rational, and the noise became quieter and quieter until it was completely silent.

As if nothing had happened just now, Han Yin did not make any transition, and opened his mouth to directly lead the topic to the central content of the profile:
"First of all, as I said at the beginning, we were wrong from the very beginning. I think this series of cases is not a sexual perversion rape case dominated by 'sex' as previously identified. Its real criminal motive essentially comes from 'anger', and the root of the anger is the lack of a sense of balance in life, which means that this case is a series of crimes 'using the means of mutilation and sexual assault, and the motivation of seeking a sense of control'."

"Everyone is very clear about the facts of the case. You should know that before the fifth case, the murderer and the victim had no genital contact. So is this really due to a physiological disorder? I don't think so! I think it is a kind of disdain and contempt! This is especially evident in Cases [-] and [-]: the environment of the scene in Case [-] allows the murderer to clearly determine that the victim lived alone, and he had enough time to do more things, and he did. Yes. The only time he stripped off all the victim’s clothes was this case; he began to cut up the victim’s organs and tissues and took them away from the scene as a souvenir, but he did not rape the corpse. And the fourth case has such a detail—the victim Or the trousers were only pulled up to the knees, presumably adults can figure it out, such an awkward position shows that the murderer never thought about having sex with the victim."

"But why did the sexual assault appear from case five? Previously we identified the murderer as suffering from intermittent sexual dysfunction. In fact, this explanation seems far-fetched from a pathological point of view. Many such cases show that despite many With sufficient treatment, it is difficult for the patient's sexual function to change from extremely weak to constant. Then what is the key to the turning point from Case [-]? It is the victim's age factor, and it is the young girl in that age group that makes him feel Feeling comfortable! I must admit that at this point, I have previously made a wrong judgment, thereby ignoring very important behavioral evidence. Next, I will focus on case five, because in the entire series of cases, this The case is critical to profiling the killer's criminal psychology and background information."

"First of all: Although I have mentioned it many times before, it is still necessary to repeat it now. On the one hand, judging from the facts of the case, the murderer must fully grasp the work and rest time inside the power supply bureau and the victim's family members in order to be able to grasp the timing of the crime; On the other hand, at the previous criminal geographical profiling analysis meeting, I have already explained to you the important position of the power supply bureau in the entire crime location. Combining the two aspects together, I can tell you clearly that the murderer lives in the power supply bureau. around the bureau."

"Furthermore: in case five, apart from the rape of the corpse for the first time, the murderer actually had two special actions, that is, the only time in the entire series of cases that he changed the killing method and hid the corpse."

"On this topic, let's first analyze the murderer's appearance and personality traits from the murder method: In this case, the murderer mostly used the lightning-style stabbing method of killing the victim's neck. Time, so that the victim loses the ability to resist and call for help. This shows that the murderer does not have enough confidence in his ability. This may be due to short stature or disabilities, such as Dong Wenyu, a serial murderer and necromancer; Deception ability, such as Zhang Yongming who caused the serial disappearance of teenagers; or because of the accumulation of frustration experience, such as the trail killer Yang Shuming. In short, I think the murderer in this case has all three, which explains why in case five, when the murderer faced When it comes to little girls who are young and ignorant and easy to manipulate and deceive, they will change their methods of killing."

"As for the act of hiding the little girl in the closet after committing the crime, it was obviously caused by guilt or even shame, but why did this kind of emotion only appear in case five? The answer is the same as the reason for the rape corpse mentioned above The same, because of the age of the victim. However, because the victim is a little girl, the murderer has the desire to rape the corpse, and therefore has a feeling of guilt, isn't there a contradiction between the two?"

"Indeed, it may seem unreasonable on the surface, but before I explain it, I would like to talk about another contradiction in the criminal behavior. Everyone knows that the murderer in this case adopted the method of 'breaking into the house', which is obviously a high point. The choice of risk, but why is the murderer so persistent? There should be two reasons: one is that in the real environment, the murderer actually does not have a house to live alone, and cannot detain the target; the other point is that in the subconscious, the murderer wants to To establish some kind of intimacy with the victim. The paradox is in this latter point, if the murderer wants to be close to the victim, why would he destroy them in such a cruel way?"

"Summary of the above contradictions, combined with the entire case, we can find that the criminal behavior has such characteristics: the murderer hates women extremely, but fantasizes about owning women; What I hate is women's rebellious and complicated adulthood. They have a good impression of young girls with simple thoughts and pure hearts and will be aroused sexually. Does this mean that the murderer actually has objects of anger? Young women and young girls are actually It is the complex of this object, and his real purpose of committing the crime is to exchange for the well-behaved and simple latter by destroying the former with negative behavior. Then, we can draw an important conclusion from this—the focus of the murderer’s anger It was his 'daughter who was then grown up'."

"Well, at this point, I believe I have brought you a new question. Since the murderer committed the crime to get back his innocent daughter, how could he commit such an act of adultery? And why did he commit suicide in the later case? , in the face of adult women he hates, will he also have sexual desire? To answer these two questions, I have to admit that the murderer did have a considerable degree of sexual repression at that time, but the point of rape is not that, it actually reflects It is a kind of mentality of trying to "possess" strongly under the impulse. Therefore, after calming down, the murderer suddenly found that he had done incest to the substitute of the little daughter, and then the little girl was stuffed into the closet. Acts that show shame. But he suddenly discovered that he had mastered a more representative way of destroying and possessing, so in subsequent cases, rape became an indispensable link in the behavior of marking, even more than The previous status of destroying corpses with sharp weapons is even more important..."

After the long discussion in one go, Han Yin paused for a while, allowing himself to rest for a while, and giving others a chance to digest the information.After a while, he continued:

"Based on the above and all the previous analysis, let me summarize for you what kind of person the murderer is: he is a local, with a small stature, a kind face, a low self-esteem personality, and a certain degree of cultural accomplishment, which is reflected in his life. Will give people a deceptive impression of being calm, low-key, inarticulate, polite, etc. Although this can quickly remove him from the identity of a murderous demon, the extremely violent personality disorder will still make him in reality. From time to time, there are abnormal behaviors, such as liking knives and playing with fire, hurting small animals, and suddenly losing your temper after being irritated by something, etc. "

"As mentioned above, the target of the murderer's anger is his daughter. It is conceivable that the daughter must have committed an unforgivable mistake in the social environment at that time, such as running away with someone against her parents' wishes due to emotional problems, or going to jail for a crime. Or his life was rotten, or he was addicted to drugs... And this mistake caused his peaceful life to take a serious negative turn, which stimulated him to constantly destroy his daughter at that time in order to seek the original balance and harmony of life. A sense of control. Then in the first crime, that is, in 1988, the age of the daughter should be after entering the rebellious period of youth. Correspondingly, the murderer was at least 40 years old at the time, and he should be 70 to [-] years old. Families live together, but maybe it’s a single dad, or the wife is seriously ill, etc.”

"The murderer lives near the power supply bureau and is familiar with the internal environment and information of the power supply bureau. Therefore, I think the family members of the employees of the power supply bureau who live in the family building should be listed as key investigation targets; at the same time, I think that in the initial stage of committing the crime, the murderer had a stable job. , the unit should belong to the smelting and mining company system, he has not achieved much in his work, and may work three shifts in time."

"I have to talk more about the issue of work. I don't know if you have noticed that the stable work I just mentioned is in the initial stage of the murderer's crime. This stage is roughly before the end of 1998. Why do you say that? Because 1998 was an extremely sensitive and turbulent year for Chinese workers, especially for smelting, a heavy industrial city with non-ferrous smelting as its pillar industry, its influence can even be described as shocking. Right here One year, a large number of laid-off workers began to emerge across the country, and most of them were industrial workers in coal, chemical, and nonferrous metal enterprises. It is conceivable that murderers who were over the age stipulated by the policy at that time could not escape the fate of being laid off."

"The unprecedented heavy blow to real life is actually reflected in the facts of the case: in the previous analysis, I intentionally left out an important feature of the case, that is, in the entire crime, 1998 was the most intensive and the interval was the shortest, and The most brutal, with a total of four crimes; at the same time, most of them were accompanied by the act of dismembering organs and tissues as memorials, among which the '98·11·30' case was the most tragic. This also means that this year is a year of psychological frustration for the murderer It has reached its peak, on the verge of, no, it should be said that it has completely collapsed. The more frequent his crimes and the more cruel his methods, the more serious his psychological imbalance! You can see in the '98·11·30' case that the murderer At that time, he began to be obsessed with the fantasy of sexual perversion. He cut off the victim's breasts, hands and genitals, probably in order to relive the crime process through touching in the future, which is also a psychological expression of extreme escapism. Of course, this evolution It often appeared in past cases, such as Yang Xinhai and Zhao Zhihong mentioned above. In the later stage of their crazy crimes, they have actually deviated from the original intention of seeking survival, releasing sexual desires and retaliating against society in the early stage. It is more a way to deal with setbacks. Habitual means of venting experience. Yang Xinhai committed a crime because he was extorted a high price by the escort lady in the bathing center, and he immediately fled to the suburbs to complete the crime because of his grievances; and Zhao Zhihong was even worse. In real life, he Not only did he have stable sexual partners based on feelings, but he also had many illegitimate adulterous partners, which means that he never lacked women and sex life around him, but when his career was hit, he went back to the previous poor The mistakes of the times, using rape and murder of women as a channel of catharsis."

"After the murderer in the smelting case was laid off, he committed two more crimes, namely Case [-] and Case [-]. Speaking of this, I must first agree with my colleague Xiao Du's analysis. The professional status of the murderer at that time may have changed to A driver; at the same time, a slight revision should be made to the previous criminal geographical profile. I think that at that time, the channel for the murderer to choose his target had changed from a bus to a 'taxi'! Specifically: the victim of Case [-] She is a nurse who works in an infant care center with delivery wards along Renmin Road. The time of victimization was after she returned to her residence from morning and night shifts. The victim in Case [-] was a businessman. After renting a private room in Huichun Hotel, you can imagine that the former chooses to take a fast and comfortable taxi because he is tired from the night shift; while the latter, with his identity and financial ability, obviously takes a taxi instead of going out. Reasonable. In summary, what I want to say is that after being laid off, the murderer made a living by driving a taxi."

"So far, I think you have a relatively comprehensive understanding of the murderer, and at the same time may have solved the two questions that have plagued us all: why the murderer seems to be related to the smelting company, but after a comprehensive investigation, there will be nothing. No results? Why are the police trying their best to search almost half of the city, but still can't catch the murderer? I think the previous problem is that when we want to focus on the smelting and mining company, the murderer has already been laid off and left The following questions are directly related to the narrow scope of our previous criminal profiling."

Han Yin stopped talking again, and raised his hand to push the mirror frame on the bridge of his nose, but he didn't seem to want to completely end the topic.Sure enough, after looking around at everyone, he went on to say: "There is one last question, and everyone must have been thinking about it, that is, in the above analysis, I have never mentioned the three cases of this year. The reason, I think These crimes are not committed by the same murderer as the previous eight crimes. Let’s talk about them in detail below:

In fact, since I took over the task of handling this case, the two cases this year have made me feel strange. Not only the age of the victim has greatly changed from before, but the personality of the murderer has also undergone a great change.Especially before and after the case just happened, the murderer first used the library call number to trick the so-called retired old policeman on the Internet, and then he personally called Team Liu to demonstrate to us, which confirms that he needs someone to agree with him It is hoped that the achievements of the world will receive widespread attention from the outside world.This is a considerable upgrade from the previous murderer personality who only cared about his own inner feelings.Of course, the escalation of criminal desires is not impossible, and it can even be said that it often occurs in abnormal serial cases, but there is one thing that should not change, that is, there was a financial loss in the case just happened, and the murderer stole it. The victim just took out 1 yuan from the bank. "

"In the previous eight cases this year, there was never a case of theft, which can prove that the murderer has a stable job in a practical sense. You have also seen the previous analysis. He also experienced layoffs and other existential crises, but Qihe In eight or two cases, especially the victim in the long private room of the Huichun Hotel, he was still unmoved by carrying a considerable amount of cash with him, which showed his extremely 'paranoid' side, that is to say, 'theft' behavior In the murderer's morality, it is the same as ordinary people's cognition, thinking that this is a shameful and humiliating act. You must find it incredible, but in the crowd of perverted serial killers, this kind of delusional paranoia It does exist, and its formation is mostly related to high-level cultural education and religious beliefs—he doesn’t think he is an outlier in this society, he is willing to abide by social morality and the legal system like ordinary people, and even more rigorously, because in his In his inner world, he has already rationalized and legalized his serial killing behavior through a psychological cognitive feedback mechanism. The most obvious example of this personality trait is the 'top student killer Ted Bundy': on the one hand, he He is a serial rapist and murderer; on the other hand, he often warns women who are not within his target range to be careful of perverts who want to commit crimes around him, and even hunted down robbers in the street."

"From my personal profession, I usually think that almost every serial killer has more or less antisocial personality disorder, but summing up all the previous analysis, I must admit that the murderer in the first eight cases only committed crimes against The individual who replaces the object of anger in fantasy has no desire to retaliate against society; the murderer who committed three crimes this year is a serial killer with antisocial personality disorder. As for the relationship between the two serial killers, we will now I'm afraid I can't explain some information, but the characteristics of the case clearly show that the killer behind has a very deep understanding of his predecessor, and the murder weapon belongs to the same type, maybe even the same murder weapon; and the acquisition of pubic hair also means that They are in contact with each other. I think that if we can catch the former, we won’t be too far away from the latter, so my final suggestion is: Although there are two murderers, they still need to be investigated together. Focus on the perpetrators of the previous eight crimes, and follow their criminal profiles to formulate a search and arrest plan!"

There was no sound in the conference room, so quiet that even a needle dropped on the ground would make people jump in fear. This was the reaction at that time.After listening to Han Yin's long discourse that perfectly combined theory and reality, all the police officers in the case-handling team seemed even more at a loss.And this is roughly the same as the situation encountered in many grassroots units before. These grassroots criminal police who are accustomed to following the actual evidence as the main means of handling cases are not very convinced by the so-called behavioral scientific analysis, but they can't find any refutation after thinking hard. argument.Therefore, more and more attention is focused on Liu Fuzhi as the decision-maker.

Of course, Team Liu understands how delicate the situation he is in now. Although Han Yin has given a relatively specific scope of investigation, due to the involvement of the power supply bureau with many employees and the entire smelting and mining company system with the largest scale in this city, the actual implementation I'm afraid it's not that easy, especially if you want to achieve results in a short period of time, that's beyond what ordinary police forces can accomplish.If the police force was really mobilized on a large scale, but the murderer was still not found in the end, how should he explain to the superiors?More sensitively, agreeing with Han Yin's analysis is tantamount to completely denying the opinions of many old leaders and experts in front of him, and it is tantamount to putting the responsibility for ineffective handling of the case for so many years on those people; It is difficult for ordinary criminal police officers to turn around emotionally for a while, so wouldn't they become the target of public criticism?However, his personal interests are not the most important, the key is what if the murderer no longer shows up during this period?If he disappeared suddenly like ten years ago, wouldn't all the hard work be in vain again?
After thinking about it, Team Liu hesitated and seemed to have a hard time making a choice.He frowned, looked around, then turned to the deputy head of the case handling team sitting on the left, and asked tentatively as if asking for help: "What do you think of Teacher Han's analysis?"

"I have reservations." The deputy team leader seemed to have long been dissatisfied with Han Yin, and replied without thinking.

"Then Team Leader Gu, what's your opinion?" Team Liu turned to the other side and asked Gu Feifei.

"From the perspective of handling the case, every word Mr. Han said does not represent him personally, but represents the opinions of the entire support team." Gu Feifei, who has always been vigorous and decisive, couldn't bear Team Liu's indecision, so her face was unhappy and cold said.

Asked as if he didn't ask, and touched two nails, soft and hard, Dui Liu showed a wry smile in embarrassment, then lowered his head and fell into deep thought, and then looked up again, only to see him take out his police officer's card from his coat pocket and throw it on the table in front of him , and then untied the pistol at his waist and pressed it on the police officer's certificate, and asked Han Yin in a desperate manner: "Are you really sure about your analysis?"

"Of course, I'm sure!" Han Yin replied frankly.

"Well, I have lost for so many years anyway, so why not lose again?" Captain Liu sighed first, then said with pride, "I will use this police gun that has been with me for more than 20 years and the skin on my body Let me gamble with you!"

Han Yin knew very well that Team Liu's gesture was largely for his subordinates to see.In this way, even if some people harbored dissatisfaction, they would not dare to make mistakes. Team Liu would go all out. How could the people below dare to speak against him?In this case, Han Yin could not show the slightest timidity, so he replied forcefully and firmly: "No, I don't like gambling. Gambling always has winners and losers. What I want is to definitely win!"

Section [-] Targeting
Time came to mid-April in a blink of an eye, and the weather did not get warmer. Instead, due to the onslaught of strong cold air, the temperature dropped sharply again.Accompanied by the chilly spring, the large-scale investigation operation is advancing with difficulty, and the time is getting longer and longer, but the suspect who fits the scope of the profile has never appeared.Doubts in the police force that had been suppressed by Team Liu began to arise, and the support team was under unprecedented pressure. Han Yin took Du Yingxiong and followed Team Liu tirelessly to the front line all day long, making himself ashamed , very hard work; besides paying attention to suspicious comments in online posts from time to time, Ai Xiaomei's more important task is to assist Gu Feifei to find the murder weapon through the fracture on the top of the victim's head.

Gu Feifei repeatedly carried out hitting experiments on a plastic head with roughly the same bearing capacity. It was previously confirmed that one end of the murder weapon was about seven centimeters long, two centimeters wide, and four corners were right-angled parallelograms, that is, rectangles. On the basis of the weight of the murder weapon, it was further determined that the weight of the murder weapon should be about one kilogram.Since the victim's daughter denied that there was such an item at home, it should be carried by the murderer, so it seems that the murder weapon is likely to be some kind of electronic product.

Afterwards, Gu Feifei and Ai Xiaomei set their sights on the major electronic product markets and online e-commerce platforms in Mining City, and extensively searched for electronic products with similar specifications and weight ranges to the suspected murder weapon. It can be used on small portable tablet PCs, MP4 audio-visual players, and handheld game consoles.The two of them searched about hundreds of such electronic digital products, but either the specifications were too different or the weight was not enough, and they still couldn’t find one that matched both, so Gu Feifei thought it was time to change the way of thinking—first come first Assume the identity of the killer, and use that identity to find matching electronics.

Taken together, there are a total of 11 cases. Although they were not committed by the same murderer, the two serial killers seem to have the ability to let people relax their vigilance.The former Han Yin has already analyzed it, probably because he is short in stature, kind-hearted, and looks older and well-educated, so he is not to be guarded against.What about the latter?What is his deceit and disguise?Could it be his identity?For example, he is a property repairman, or a deliveryman in a supermarket, or a courier?Property repairmen may carry testing instruments with them, so what kind of electronic products will supermarket delivery men and couriers carry?

…By the way, if customers ask to swipe their card, do they have to bring a mobile POS machine?

At the end of April, the weather showed signs of improving completely. The spring breeze was warm and warm, and it was no longer a bleak feeling. The smelting and mining city finally had a taste of spring, and the investigation work also made significant progress.As the demolition and reconstruction of the family building area of ​​the original power supply bureau was completely completed, the demolished people successively registered for relocation. Some old employees of the power supply bureau who could not be found in most of the cities before, that is, the old residents of the family building, all showed up one after another, in line with the profile The suspect finally surfaced.It's just that he has been dead for more than half a year, so it's embarrassing!
The suspect is Shan Xiongye, a local smelter, born in 1944, 1.65 meters tall, with a gentle personality and a college degree. His wife died of illness in June 1987, leaving behind a daughter and a son; He worked in the power system in the 6s, and was also the first batch of employees after the official establishment of the Mining City Power Supply Bureau. He naturally became the first batch of occupants after the completion of the family building of the Power Supply Bureau in the late 20s.Shan Xiongye himself was an instrument worker in the main factory of the Metallurgical and Mining Company. He was officially laid off in 50 on a shift system. After that, he made a living by opening a "noodle shop". In 20, his parents passed away due to old age. In mid-September last year, He himself also died of testicular cancer.

This person had entered the line of sight of an investigation team earlier, but he was not included in the key investigation object. The reason was that the information obtained at that time was not detailed enough, and some of his background information was quite different from the scope of the profile—in Korea According to Yin’s profile, the murderer was born near Renmin Road and has been living in this area, but the suspect actually left Yekuang City in 1963 to study in other provinces, and stayed there after graduation to work, marry a wife and have children. , It was not until his wife died of illness that he was transferred back to work in the smelting mine at the beginning of 1988, and lived with his parents in the family building of the power supply bureau.

In fact, if the investigators in this group knew more about criminal profiling, they should not have ignored this person earlier.On the one hand, as an auxiliary means of investigation, criminal profiling is not completely rigorous, and its effectiveness must be combined with the actual situation; The time is so close to the time when the first murder occurred, could the two be the stimulating incentives for him to commit the crime?

Han Yin came into contact with the above information by chance and went deeper, and visited some old neighbors of the suspect again. These people reported that they had learned from the suspect's father in the chat that the suspect had always liked boys and because of his ethnic identity He belongs to an ethnic minority and conforms to the two-child policy, so his wife gave birth to a son for him after she passed middle age. However, because she was an advanced mother, her body was weak and difficult to adjust after giving birth. In addition, her daughter who was in a rebellious period often He played truant and was difficult to discipline, so he became ill from overwork and became seriously ill. He died of a serious illness.At that time, the daughter was 18 years old and the son was less than two years old.This supports the source of the murderer's crimes pointed out in the profile, as well as the related speculation about his daughter.

The background information of the suspect is so consistent, the next step seems to be very simple.Because he has passed away, it is impossible to directly collect effective DNA samples, so it is possible to compare the DNA of his children with the DNA obtained at the scene of the crime earlier, or use the relics provided by his children with his fingerprints for comparison. His identity as the murderer was fully confirmed.

In fact, the case is not going as smoothly as Han Yin imagined.

Through the information registered at the relocation registration office, Team Liu contacted Shan Huaming, the son of the suspect Shan Xiongye, and Shan Yingchun, the daughter, and invited them to the team.But before Dui Liu finished speaking, the siblings flatly rejected the police's request for assistance with one voice, especially the middle-aged sister, who reacted more resolutely and fiercely. She even ignored Dui Liu's request With Li's persuasion, he forced his younger brother to leave the criminal police team.But if you think about it, you can understand the reaction of the siblings. After so many years, who would want to prove that his dead father is the most violent sex murderer in the city? !

Since the ideological work of the children cannot be done for the time being, and since Shan Xiongye has no relatives in the local area, he can only try to find a way from himself.Through multiple inquiries, Team Liu learned that Shan Xiongye was admitted to the No. [-] People's Hospital of Yekuang City after suffering from cancer, so he and Han Yin rushed to the hospital as soon as possible, hoping that the hospital could keep the specimens for treatment and testing at that time.

At the No. [-] People's Hospital of Yekuang City, they successfully found Shan Xiongye's medical records. The blood type recorded on it matched the murderer's. This greatly strengthened Han Yin's confidence. It was disposed of and no further DNA samples could be provided.The two still didn't give up, and asked to see Shan Xiongye's attending physician, and wanted to ask him if he kept the items that Shan Xiongye had touched, but the meeting was in vain.However, what surprised Liu Dui was that he had dealt with this attending physician before. His name was Zhao Liang, and he was the younger brother of Zhao Lin, the first victim in the whole series of cases.

Although the hospital party did not achieve the expected goal, it was not without any gains. Zhao Liang's unexpected appearance seemed to be like his name, illuminating a new direction for the case—Zhao Liang was both the victim's younger brother and the key point. The suspect's attending physician had contacts and intersections with both the aggressor and the victim, so Team Liu put forward a hypothesis: "If Shan Xiongye is really the murderer in the first eight cases, then could Zhao Liang be the murderer in the last three cases?" Woolen cloth?"

Han Yin did point out in the profile that the murderer was not the same before and after the crime, and the two may have some kind of intersection.This Zhao Liang appeared out of nowhere, and his identity was indeed quite sensitive, but Han Yin couldn't imagine what kind of motive he had for committing the crime.Of course, he thinks it is still necessary for Team Liu's suggestion to conduct a comprehensive investigation.

But things in this world are always changing rapidly, and what was extremely difficult just now may become extremely simple immediately; or just now I thought I picked up a treasure, and it became worthless in an instant.

On the way back from the hospital, Team Liu received a call from the team, saying that Shan Huaming, the son of Shan Xiongye, unexpectedly came to the criminal police team and expressed his willingness to cooperate with DNA testing.This is really a turn of events, and the two couldn't help being excited for a while.Is this the case?No, the happy mood of the two didn't last long before another big reversal happened.A few hours later, the DNA test and comparison were completed, and the results showed that Shan Huaming and the murderer were not father-son, which meant that his father, Shan Xiongye, had nothing to do with the previous eight cases at all!In this way, Zhao Liang, who has an intersection with Shan Xiongye, loses the value of investigation!

The key suspects who worked so hard to lock down were finally eliminated. The investigation and investigation that took more than a month was in vain in the end.Should we follow the profile and continue the investigation, or stop the operation in time to find another direction for investigation?Faced with pressure from the outside world and inside, Team Liu knew that he had to make a decision as soon as possible.

Not only him, Han Yin himself is also thinking about the current situation, should he adjust the direction of investigation appropriately?In fact, since confirming the personality traits of a murderer, he has been brewing a "proactive strategy", but the central point is to anger the murderer, so he is very hesitant, worried that the murderer will finally vent his anger just like the case above to the innocent, so he only discussed it with the hero in private, and didn't mention it to anyone else.

The current situation makes the support team's position in the entire case-handling team very awkward. If the case still does not progress after a little more time, I am afraid that all responsibilities will be assigned to the support team, and it will also damage the entire serious case support department. Reputation, so apart from Han Yin, the other three people in the group were also extremely anxious.

Gu Feifei previously changed her thinking, assumed the identity of the murderer, and inferred the type of murder weapon in reverse. From this, she thought of the courier of the courier company and the deliveryman of the supermarket. Most of the machines are square and square, which can cause the four sides of the top of the victim's head to be fractured at right angles.Through multiple visits and investigations, there are only two supermarkets in Fuping District that provide door-to-door delivery services, but they only accept cash; and there are three express companies that can provide cash on delivery card swiping services in the entire Smelting and Mining City. After comparison, these three companies The POS machines uniformly equipped for couriers do not match the outline of the fracture.

Both the evidence and the investigation of physical evidence encountered bottlenecks, and the hero could no longer calm down, and couldn't hold back and told Ai Xiaomei the trapping plan that Han Yin had discussed with him.After all, Xiaomei is young and does not have as many entanglements as Han Yin. Naturally, she is not cautious when considering issues. Impulsively, she encourages the hero to go to Team Liu with her, and discuss a specific plan according to Han Yin's plan.In short, no matter what, solving the case is the most important thing.

Han Yin's proactive strategy is related to online posts made by people pretending to be retired veteran policemen on forums.He believes that until now, the murderer still pays attention to the replies to the posts in that online post from time to time, because his original crime may have been inspired by the online post, and he felt a sense of accomplishment as a serial killer from it—that kind of wanton manipulation He is deeply fascinated by the sense of achievement of controlling, dominating, and controlling the situation, and he pursues it unremittingly.If he finds out that the old policeman is a fake, and the person who is really fooled is himself, he can imagine how angry he will be. With his anti-social personality, he will definitely want to take revenge on the person who posted it. It gave the police a chance to catch a turtle in the urn.

In Han Yin's vision, of course, the real information of the poster will not be disclosed. In order to "seduce" the murderer to the maximum extent, he will design the poster to be the type of target that the murderer likes to infringe-middle-aged housewives, and the place of residence is also designed. In Fuping District, which the murderer is familiar with, Ai Xiaomei was asked to apply for a few "vests" on the forum, in the name of exposing the poster's lies, and exposed the carefully designed poster's information in the form of comments.

After listening to the hero's narration, Liu Dui, who is in a difficult situation on all sides, can be said to have picked up a life-saving straw. He actively expressed that he will immediately start arranging suitable candidates and setting up trapping locations. to take charge.A secret entrapment operation started...

Section [-] Ultimate Goal
When Han and India learned of the news, the sting operation had been deployed.

According to the settings in the Korean-Indian proactive plan relayed by Du Yingxiong, Team Liu deliberately selected a female policeman in her 40s with a gentle face and no obvious police temperament from a police station in a certain jurisdiction to pretend to be the poster, and opened the post in a certain area in Fuping District. I rented a two-bedroom house in a unit building in the community; a large number of plainclothes were arranged inside and outside the building, as well as several main entrances and exits of the community, and they were guarded 24 hours a day to prevent mistakes; Team Liu was still on the street of the unit building. Surveillance probes are concealedly installed on the street lamp stand next to it and in the corridor.Liu Dui believes that if the murderer intends to retaliate against the poster, he may repeatedly step on the site and observe the surrounding environment of the crime scene in advance.In order to avoid arousing his suspicion, Liu team will arrange female policemen to come out to buy vegetables, go for a walk and so on at an appropriate time. Of course, at this time, there will be a plainclothes relay to protect her.

Ai Xiaomei's "fanning the flames" in the online posts also went relatively smoothly, and successfully provoked the anger of many deceived netizens, presumably there is a murderer among them.She first used a "vest" to claim that she had an acquaintance in the police station. She said that she had learned from the acquaintance that the online post had attracted the attention of the police. It is inconvenient to reveal the real identity of this netizen, so I call on everyone to search for her human flesh; then, she logged into several "vests" one after another to stir up this topic, and then saw that the heat was almost ready, and then revealed the designed poster information in detail , including age, family situation, photo, address, etc.

For this reason, Gu Feifei and Han Yin were quite annoyed, but the situation was irreversible, and they could only wait and see the progress of the action, praying that the result would develop in the ideal direction.But the fact is just as what Han Yin worried about before, the murderer has not appeared in the police's monitoring sight for many days, but this does not mean that he is not provoked!
This morning, just after dawn, people who like morning exercises in a residential area in Chaoyang District have gone out one after another.There is a fountain in the community, and an open space around it is specially used for morning exercise by the residents of the community; next to the pool is a promenade covered with vines, with a few stone benches inside, for the residents to take a rest.It can be said that this area has always made them feel peaceful and soothing in the past, full of leisure and leisure.But this morning, what they saw in front of the corridor was an eye-popping scene!
A naked middle-aged woman, with her hands and feet tied to the concrete pillars on both sides, hangs in the shape of a "big" at the entrance of the corridor.The breasts and lower body are exposed, and the upper body is almost covered with stab wounds.The fatal injury was still the slashing at the neck, the incision was very deep, almost the entire head was cut off, only a layer of skin was attached, hanging on the back.The most tragic thing was her face, which was bloody and bloody from the knife. The murderer might feel that he was still wanting to peel off her face, but perhaps due to lack of experience, only part of the flesh on both cheeks was torn off. Two patches of red were painted on the cheeks; more than half of the two eyeballs were gouged out. Judging from the rough edges of the scars, it should have been pulled out by hand... This is the 12th victim in the entire series of cases. If Said that her appearance did not exceed Han Yin's expectations, then what everyone never expected was that she was actually Shan Yingchun, the daughter of Shan Xiongye who was the key suspect in the previous investigation!
"How could it be her?" Han Yin walked around the corpse, put his hands in his pockets, fixed his eyes on Shan Yingchun's face hanging on his back, and muttered to himself, "Why is the murderer this time?" Doing so many movements on the victim's face? By the way, why isn't there a red cloth around the neck?"

Shan Yingchun, in her early 40s, is a full-time housewife, her daughter is in a boarding middle school, her husband is a business manager of a trading company, and she lives in a high-end residential area on Tianhe Road, Xiangyang District.

There is only a small amount of blood near the promenade. Shan Yingchun's body was obviously moved after her death. She lived in a unit building about 20 meters west of the morning exercise site in the community. After investigation, it was confirmed that her residence was the first crime scene. .According to the forensic autopsy, the time of his death was between 9 o'clock and 10 o'clock last night. Compared with the knife wound on the corpse, it was from the same type of murder weapon as in the previous case.In addition, no physical evidence related to the murderer was collected at the scene, but a black ballpoint pen was found in the stairwell on the floor where the scene was located, and multiple fingerprints were extracted from it...

In fact, just looking at Shan Yingchun's personal background information, it is in line with the target standard that the murderer has always pursued, but other than that, the characteristics of the case are still quite different from the previous case.

First of all, the crime area was transferred from Fuping District to Chaoyang District, the crime scene was changed from a low-end open residential area to a high-end residential area with relatively tight security, and the crime time was also changed from daytime to midnight.Of course, this last point may be limited by the environment of the crime scene - if a crime is committed in such a community with security guard boxes at the entrance and exit and camera surveillance, if you don't want to leave traces and not be photographed by surveillance, you may have to take The method of climbing over the fence to enter the community at night, in fact, the investigators did not find any suspicious figure on the surveillance video of the entrance and exit of the community.Then, digging deeper, the changes in the environment and time of the crime scene also seem to indicate that the murderer has a certain degree of understanding of the victim.Last night, the victim's husband was on a business trip, and the daughter boarded at school, so she was left alone at home, and the murderer chose to commit the crime on this night. Is it just luck or a coincidence?

Secondly, the perpetrator extended the range of corpse abuse to the victim's face, which has never happened in recent cases.In the previous case, the blow to the victim's head was due to an accident during the homicide, which had nothing to do with the criminal marks.From the perspective of criminal behavior analysis, it is generally believed that consciously targeting the frontal aggression on the face means that the aggressor and the victim are acquaintances, because the face more specifically represents her.This also shows that in this non-empathy crime, the victim Shan Yingchun himself was the one the murderer wanted to take revenge and destroy.

Furthermore, the perpetrator moved the body and exposed the body to the public.Such a humiliating method undoubtedly shows that the murderer has more resentment towards Shan Yingchun than all the previous victims.

Also, don't forget that the murderer committed the crime this time after he found out that he had been severely fooled by the online posts.As analyzed earlier, that online post was essentially the motive force and faith guidance for the murderer to commit the crime, and once he found out that all of this was just an illusion, the self-confidence built up through serial killings would completely collapse.He was beaten back to his original form, and he even felt more embarrassed and inferior, and the anger that arose at the historic moment would be unprecedented, so under such a time and psychological background, Han Yin believed that he would definitely vent his anger on his On the person who most wants to punish.

Based on the above analysis, Han Yin believes that Shan Yingchun may be the ultimate goal of the latter killer. The previous cases this year may be just a foreshadowing. The murderer and Shan Yingchun must have overlapping interests in reality, and their relationship is even quite close!
But there is one thing that Han Yin still can't figure out: why is it Shan Yingchun?Is there any connection that she was killed just after the police ruled out her father's involvement in the earlier case?Is it just another coincidence?
According to Han Yin's analysis, the next action to handle the case will revolve around Shan Yingchun's social relations.

Shan Yingchun has not worked since she got married, and her life circle is relatively narrow. She usually focuses on taking care of her children and serving her husband. In addition, it was introduced earlier that her mother died early and her father died of illness half a year ago, so it is more obvious that , and her closest relationship is only her husband, daughter and younger brother.Needless to say, the daughter is just a junior high school student, so it is impossible for her to commit the crime; so would her husband and younger brother have a motive for committing the crime?Regarding this line, Han Yin and Gu Feifei decided to follow up personally. With the assistance of Team Liu, they visited many friends, neighbors and colleagues who had been in contact with the two, and found that the relationship between the family was not very harmonious.

Shan Yingchun's husband is Yu Ning, who is 10 years older than her. They met in 2000 through someone's introduction.At that time, Yu Ning had already experienced a marriage, but fortunately, there were no children in that marriage, and his career and financial conditions were relatively good; at that time, Shan Yingchun was an older woman, so the two got married after dating for half a year.A year after marriage, they had a daughter, and then the family of three lived a stable and happy life.Until two years ago, Yu Ning met a young and beautiful saleswoman during his business dealings, and since then, things have changed.He bought a house for the saleswoman and paid high monthly living expenses. In essence, he was a treasure in the golden house and took care of the girl.According to Yu Ning's friends, the relationship between Yu Ning and the girl is basically semi-public in his circle of friends. He is particularly obsessed with the girl. For this reason, he has proposed divorce with Shan Yingchun many times, but Shan Yingchun always disagrees.

Judging from the information learned from the surroundings, it seemed that there was a motive, so Han Yin and the others turned to make positive contact with Yu Ning.However, Yu Ning said that when the incident happened, he was on a business trip in a neighboring city, and many people in his company could confirm his statement.However, this does not completely rule out his suspicion. As long as you have money these days, you don't need to do many things yourself.Subsequently, the police conducted a comprehensive review of the phone calls, emails and other communication records of Ning and his lover, as well as company accounts, personal deposits, bank card expenditures, etc., and screened their social interactions again. Found signs of hiring a murderer to kill his wife...

Shan Yingchun's younger brother, Shan Huaming, is a master who can't eat enough and can't do anything.He dropped out of junior high school and mixed in the society. He was lazy, got into fights, and often lingered in low-end bars, karaoke halls and other entertainment venues. A lot of money; I had two girlfriends, one ran away with someone, and the other broke up with him because he thought he was poor.

The age difference between him and his sister is too big, and the generation gap is obvious. In addition, his father likes boys and is too partial, so the relationship between siblings has always been bad.Of course, the biggest grievance is still on the house issue.Shan Xiongye left a will after his death, and the two siblings who moved back to the new house were half of each other, which made it difficult for Shan Huaming to accept.Because my sister now lives in a large house of hundreds of square meters and lives affluently, but she still greedily occupies half of his new house; moreover, his father has always spoiled him, so how could he give half of the house to his sister?So he thought that his sister must have made trouble about the house, so he quarreled with his sister over and over again.Regarding the activities on the night of the incident, Shan Huaming said that he stayed in the rented house all night (due to the demolition of the old house, he and his father temporarily rented a house in Chaoyang District) and did not go out, but at the same time he also admitted that he lacked witnesses.

Apart from his lack of conclusive alibi, there is another identity that makes Shan Huaming look suspicious—he is currently working as a courier for a courier company, and he is in charge of Fuping District, where cases frequently occur this year. .Mentioning this point, Gu Feifei's eyes lit up, because she thought that the murderer might have such a disguise before, which made the victim relax his vigilance when he was in close contact.It’s just that the POS machine has been ruled out as the murder weapon corresponding to the identity of the courier, so what else is there?Shan Huaming delivered the parcels by electric bike. He was worried about the goods being stolen. Most of the more expensive goods were put in his backpack when delivering the parcels.Could it be that in the third case this year, because of the victim's resistance, the goods in the backpack were scattered, and then he picked it up as a murder weapon?It is not difficult to prove this point. Go to the courier company he works to check the loss of goods, and it should be clear.

There is another key issue, which is very troublesome to sort out: if Shan Huaming killed his sister, it means that he is the last serial killer in Han Yin's mouth, so how is he related to the previous serial killer? related?How did he gain insight into all the secret information and get the murder weapon and pubic hair?By the way, there is another physical evidence that can be compared - in the stairwell on the floor of Shan Yingchun's house, investigators found a black ballpoint pen, and multiple fingerprints collected on it all came from the same person.

After comparison, the fingerprints did not match those left by the murderer at the scene a few years ago, and they did not belong to Shan Huaming. However, after searching in the fingerprint system, it was found that there was a match, and it was also from a person who had appeared in the sight of the police. People - Zhao Liang!
Zhao Liang, the name that had flashed across the list of suspects, now came into the sight of the case handling team again because of a ballpoint pen left near the crime scene, but what still puzzled everyone was that he had a motive for committing the crime ?
If the former suspect, Shan Xiongye, is confirmed as the murderer of Zhao Liang's sister, then Zhao Liang's killing of Shan Yingchun can be regarded as an act of revenge, but the problem is that Shan Xiongye has been ruled out as the suspect; contact Han Yin again According to the behavioral analysis, Shan Yingchun was a very clear target of infringement, that is to say, even if Shan Yingchun was indeed killed by Zhao Liang, it may be because of the grievances between the two of them and has nothing to do with Shan Xiongye.With regard to the current physical evidence, after discussions between the case handling team and the support team, it was decided to summon Zhao Liang according to the law, and sent multiple groups of people to search his residence and work unit. Clarify the motive of committing the crime as soon as possible to lay a solid foundation for the next step to comprehensively solve the case.

In the interrogation room, Zhao Liang, who is not tall, looks upright, with thick eyebrows and big eyes, sat on the interrogation chair with a face of inexplicability. Behind the long table opposite sat Liu Dui and an assistant, and Han Yin and Du Yingxiong stayed next door to observe. The room concerned the interrogation.

After a series of regular interrogation sessions including name, age, unit, etc., Team Liu turned the question to the main topic: "Do you know Shan Yingchun?"

"I know!" Zhao Liang replied without thinking, and then asked, "Could it be that I was brought here because of her?"

"You answered very quickly, you seem to be quite familiar with each other." Team Liu ignored Zhao Liang's question, stared at him meaningfully and asked again.

"It's not just familiar, it's really impressive." Zhao Liang chuckled and said, "Because of her and her younger brother's unreasonable troubles, I almost couldn't be a doctor!"

"What's the situation, let's talk about it carefully." Team Liu cheered up, thinking to himself, "Could it be that Zhao Liang revealed the motive of the crime inadvertently?"

"Actually, it's nothing. As doctors, we see people like them a lot!" Zhao Liang explained with disdain, "Her father suffered from testicular cancer, and it was found to be in the terminal stage, and the cancer cells had spread quite aggressively. As the attending physician, I told them that resection was not recommended, and that radiotherapy and chemotherapy combined with traditional Chinese medicine combined with traditional Chinese medicine would have a better effect. But the siblings did not know which tendon was wrong, and surgery was necessary. After removing both testicles of Shan Xiongye, he passed away within a few months! The siblings may not be able to accept it emotionally for a while, and insisted that there was something wrong with my operation, and they went to the hospital and the department to make troubles all day long. I couldn't control it so I beat her brother..."

"I remember you were a high school student back then. You were gentle, polite, and spoke in a very soft voice." Before Zhao Liang finished speaking, Team Liu interrupted him with emotion, and then changed his tone, "We are I found you largely because your fingerprint records were found in the fingerprint system. I was surprised that you had a criminal record after being detained for domestic violence. How could you become so violent when the patient's family members made a move?"

"How did I become like this, don't you know? You, you, who has ever seen his sister naked, surrounded by blood, stabbed like a hornet's nest by a knife?!" Zhao Liang frowned and stared angrily. But there was a hint of choking in his tone, "You know? Until now, I often wake up from my dream because of that scene. After waking up, I feel that every organ in my body is being torn apart, as if I have been pierced by countless needles." Pain, a kind of inexplicable anger will gather in my body from all directions, and you have never given me and my sister an explanation!"

Afterwards, Zhao Liang's sobs turned into sobs, tears overflowed, and the atmosphere was a bit sentimental, so Team Liu had to pause the questioning and signaled his assistants to get some tissues for Zhao Liang.

"Well, I won't go around in circles anymore. Shan Yingchun died and was murdered. The time is..." After a while, seeing that Zhao Liang's mood gradually calmed down, Team Liu continued to ask, "Where were you that night? What were you doing?" What?"

"Oh, that day..." Zhao Liang raised his head and recalled a little bit, and said, "I should be resting that day. So I slept until after nine o'clock in the evening, got up to get something to eat, read a book for a while, and then went back to sleep. Why, do you doubt me?"

"Haven't been out all night?"

"No!"

"Have you ever been to Shan Yingchun's house?"

"Why should I go to her house? Besides, I don't know her house at all!"

"Do you have any witnesses?"

"I'm divorced and the child was awarded to my wife. Now I'm a widow. Who can I ask to prove it in the middle of the night?"

After asking a few more questions, Team Liu took out an evidence bag from the evidence box beside him and handed it to his assistant.The assistant stood up and walked to Zhao Liang, holding the evidence bag in front of his eyes.Liu team followed up and said: "We found the pen inside at the gate of Shan Yingchun's house. There are several fingerprints on it. We have compared them with your records in the fingerprint system. The results are completely consistent. This is your how to explain?"

"I admit that this is the pen I use to write prescriptions at work, but I often lose it. I bought a lot of these pens, and I don't know how many of them have been lost." Zhao Liang paused for a while, and then said a little angrily, "My temper is quite irritable, but I won't kill people, right? What are you guys doing? You can't solve the case, and you want to blame me, don't you? Obviously, my sister and I are the victims, so why am I now a murderer?"

"What are you excited about? The pen you used was left behind at the murder scene. What's wrong with us interrogating you according to the procedure?" Team Liu seemed to have been poked into a sore spot, squinting his eyes and said angrily.

……

The atmosphere in the interrogation room became more and more tense, and at this time, Du Yingxiong, who was on the other side of the one-way glass, was scratching his head and peeping at Han Yin beside him from time to time—since he planned and implemented the trapping plan with Team Liu on his own initiative. , Han Yin never looked at him directly, and the plan finally achieved the worst result Han Yin expected, which made him feel ashamed in front of Han Yin, so he followed Han Yin's ass obediently these days, Those who don't talk too much, even if they have new ideas in their hearts, don't dare to speak out rashly.

In fact, Han Yin can understand the hero's eagerness to solve the case. After weighing the pros and cons, he is very likely to make the same choice as the hero, so he has long since stopped being angry with the hero. He just feels that it is necessary to learn a lesson from this matter. he.For the police to solve a case, the result is important, and the process is equally important. You can't go beyond the boundaries of laws and regulations in pursuit of the ultimate solution to the case, and you can't ignore the potential harm that the people may suffer...

At this time, seeing Du Yingxiong's aggrieved expression of hesitating to speak, Han Yin couldn't help laughing in his heart, but he was still very serious on the surface, and said in a cold tone: "Speak up if you have something to say!"

"Uh, that's it, I have some ideas." Seeing Han Yin stepping down the steps for himself, Du Yingxiong said in a hurry, "I reviewed the file of the first case last night, and it showed that the victim Zhao Lin's parents Unfortunately, she died in a car accident in her early years, leaving her and her younger brother to depend on each other. It can be said that Zhao Liang was raised by her alone. The relationship between the siblings must be quite deep. At the time of the incident, Zhao Liang was just a sophomore in high school. He found his sister after returning home from school Corpse. I think such a life experience, for Zhao Liang, who is in adolescence and whose outlook on life and values ​​is not mature enough, will make him feel that God is not fair to him from the bottom of his heart, and gradually develop anti-social emotions ; especially the sensory stimulation when he saw his sister's dead body may cause damage to his heart and lead him to violent tendencies; If his career suffers a setback, it is likely to stimulate him to focus his anger on Shan Yingchun."

"This kind of personality transformation is not impossible, but why did he kill the other three female victims?" Han Yin said doubtfully.

"Oh, it's not easy to explain! From the information we have so far, apart from the fact that Zhao Liang lives in Fuping District and has something in common with the three victims, we haven't found any other places where they overlap." Du The hero paused, thought for a moment and said, "Could it be like this: his ultimate goal is Shan Yingchun, but killing her alone will easily expose the motive of committing the crime. If he achieves the goal of revenge by imitating the serial killers in the early years, it will be very useful. It may make us ignore his relationship with Shan Yingchun, thus drawing our attention away."

"This kind of analysis makes sense in theory." Han Yin nodded slightly, but then changed the topic, "But this brings us back to the question that we were least able to guess before: how did he connect with the serial killers in his early years?" The one on the top? Where did the pubic hair come from?"

"This..." Hero was asked all of a sudden, and he couldn't help shaking his head in frustration. After a long time, he suddenly shouted excitedly, "Could the serial killer in the early years be Zhao Liang's former patient? Maybe he is now Already dead, Zhao Liang knows his past crimes, so he borrowed his killer identity?"

Han Yin and Du Yingxiong are discussing to the critical point, and the situation in the interrogation room has also undergone a turning point.Just now a police officer knocked on the door and went in, and handed Team Liu a blue folder. Dui Liu, who had a stern face earlier, opened it and only glanced at it, then couldn't help grinning slightly, with a faint trace of Come with a smile.

"Well, if it was accidental that your ballpoint pen was left at the murder scene," Team Liu intentionally stopped halfway through his words, and then asked coldly, "Then explain why it was found in your locker." What about the jackknife that matches the murder weapon? And it passed the reagent test, and there are still traces of human blood on it."

"Ah, how could it be? The murder weapon is in my locker? How could this be? How could this be..." Zhao Liang was so surprised that he jumped up from his chair. Getting smaller and smaller, it doesn't look like asking a question, but seems to be trying to think of a way to deal with it.After being dazed for a while, he sat back on the chair silently, bit his lips, and with an obstinate appearance, he argued bluntly: "Someone must be trying to frame me! As I said just now, I am usually careless in life, so Sometimes I left the key on the lock of the locker and forgot to take it out, if someone really wanted to make me a scapegoat, they must have stolen the key while taking advantage of that opportunity."

"You don't have to act any more." Team Liu snorted and said, "In addition to Shan Yingchun, we believe you also killed three other women on January 1, March 20 and March this year. ——Our people have just investigated in the hospital and found that the three cases also happened on your day off from night shift."

"Since the divorce, my life has basically been tossed between work and home. I admit that when the other three cases you mentioned happened, I didn't have an alibi, but I can still explain it." Maybe I feel guilty There is no escape, although Zhao Liang tried his best to defend himself, but he could hear a sense of powerlessness in his tone, "We have a shift schedule every month, which is pasted on the door of the nurse's office. ;Also, in fact, our night shift is very regular. Again, if someone wants to frame me, it is easy to figure it out."

"Don't you think this kind of reason is far-fetched?" Team Liu twitched the corner of his mouth and said sarcastically, "Even if that's what you said, then who do you think would want to frame you?"

"I, how would I know!" Zhao Liang yelled, and then he shook his head in his hands and looked helpless. Finally, he raised his head and said in despair, "You all think I'm the murderer, right?"

"It's not us who identified you, it's the evidence who identified you!" Team Liu said solemnly.In fact, he didn't have much joy in his heart at this time. Just like Du Yingxiong thought, he felt that Zhao Liang's transformation into what he is today is not unrelated to his sister's killing. Everything was caused by that demon.Team Liu couldn't help asking, who is he? "How did you come up with the idea of ​​imitating the murderer who killed your sister?"

"What nonsense? I can't understand what you're talking about. You know how much I hate him, how can I imitate him to kill people? If I really become a murderer, then he must be the one who dies!" Zhao Liang seemed After being insulted, the emotion rebounded again.

"No if, you already are! Didn't many people say that as time goes by, people will become the kind of person they once hated and hated the most!" Team Liu replied sadly.

No.11 section red mark
Although Zhao Liang did not plead guilty, the relevant evidence chain has basically been formed, and there is only one link missing, which is the intersection between him and the murderer who killed his sister.On this point, Du Yingxiong's analysis is very reasonable, maybe the murderer exists among the patients that Zhao Liang once treated.According to this direction, the case handling team began to sort out the medical records handled by Zhao Liang, looking for objects that fit the scope of Han Yin's profile.Unexpectedly, after Gu Feifei confirmed the murder weapon, another suspect appeared. This person was no stranger to the investigation team. He was the son of Shan Xiongye and the younger brother of Shan Yingchun——Shan Huaming.

While the investigation team focused on Zhao Liang, Gu Feifei still did not give up on the investigation of the murder weapon.After such a long period of time, Gu Feifei has a faint intuition in her heart after excluding several electronic digital products that may be the murder weapon. If it can be tracked down, it is very possible to narrow down the murderer to an extremely small range.

She suspected that the murderer was a courier before, and she had great hopes for the mobile POS machine carried by the courier, but the result still disappointed her, and she had to temporarily put aside the direction of tracking down the courier.However, following the murder of Shan Yingchun, and Han Yin speculating that the murderer might come from an acquaintance around her, Shan Huaming, Shan Yingchun's younger brother who was a courier, was included in the scope of investigation.Although it is still not clear that he is suspected of committing the crime, his occupation fits Gu Feifei's previous analysis, so she decided to pick up this line again, go deep into the courier company where Shan Huaming works, and focus on sorting out the goods he handled. , did not expect to get a big surprise - it turns out that the courier of this express company not only carries a mobile POS machine, but also has a "wireless gun"!
Regarding the barcodes used by logistics and express delivery companies, to put it simply, the courier uses the barcode to scan the barcode on the express when receiving and delivering the express, so that the express information can be directly transmitted to the management center through the mobile network platform, so that the company can carry out the express delivery data. Real-time processing, but also convenient for customers to inquire about various information of express shipments at any time.As for the company that Shan Huaming works for, its entire Pakistan gun management system is imported from abroad, and the corresponding Pakistan gun equipment is much bulkier and bulkier than domestically produced equipment, and its weight and bottom specifications are in line with Gu Feifei's The previous delineation of the corresponding scope of the murder weapon, and the fact that its shell material is the same as the engineering plastic fragments collected from the victim Liu Hongyan’s hair, means that the Pakistani gun used by the company is the type of murder weapon that caused Liu Hongyan’s head fracture. Greatly increased Shan Huaming's suspicion of committing the crime.What makes Gu Feifei even more suspicious is that the person in charge of the company department said that Shan Huaming claimed to be cut down by a motor vehicle while delivering the package some time ago, causing the gun to be crushed and the work clothes he was wearing torn, so He borne most of the expenses himself, and applied for a gun and a set of work clothes from the company, which fit the characteristics of the case of Liu Hongyan: because of an accident in that case, Shan Huaming accompanied him during the fight. The pistol he was carrying fell out of the bag, so he picked it up, and the bottom of it slammed down on the top of the victim's head, eventually killing the victim, damaging the pistol, and staining the victim's work clothes. There was blood, so he had to replace them all with new ones.

Either it doesn't appear, or when it appears, there are two suspects at once.In comparison, from various evidences, especially physical evidence, Zhao Liang is more suspected of committing the crime.He knew the victim, Shan Yingchun, and had a motive for her murder; at the same time, all the cases this year happened on his rest day after night shift, which can be regarded as a time pattern of committing the crime; especially comprehensive The blood stains on various parts of the pocket knife found in his locker are consistent with the DNA comparison of Shan Yingchun. Three other victims of this year and two cases in the early years were also collected on that knife. The victim's blood, this is no longer a matter of matching the type of murder weapon, but it can be completely confirmed that this pocket knife is the murder weapon throughout the case from 1988 to the present.Although Shan Huaming had access to the blunt instrument that caused Liu Hongyan's head fracture, he could not be clearly identified because it had been destroyed; however, Shan Huaming's behavior of destroying evidence seemed to indicate that he was the real murderer.Han Yin felt that the key to identifying the real murderer was to see which of the two of them had something to do with the murderer in the early years.

At present, in the cases handled by Zhao Liang, no one who fits the profile has been found, and Shan Xiongye, who was originally considered the most suspicious by Shan Huaming, has also been ruled out.Since it is impossible to find a person who fully meets the profile for a while, Han Yin thinks that he might as well try the strategy of seeing the big from the small, and start from a certain detail to find a breakthrough. For example: if there is a real murderer among the two people, then How did he accurately understand the plot of the crime that only the police and the murderer knew back then?Han Yin felt that he might have read a record of the murderer by chance.

Judging from the characteristics of the crime in the early years and the profile written by Han Yin, the murderer has a restrained personality, rarely communicates with others, has a considerable level of education, and has a certain degree of tolerance and self-control.Except in 1998, when he was laid off and caused a psychological breakdown, the time interval between other crimes was kept at one or two years or even longer. Han Yin believes that such a long cooling-off period should be due to the maintenance of a certain "carrier" Combining the personality characteristics and cultural accomplishment just mentioned, Han Yin believes that the murderer may record all the details before and after each crime, and will read it repeatedly afterwards, so as to relive the pleasure of killing.Next, let's see if there is anyone around Zhao Liang and Shan Huaming who is used to recording their emotions, anger, sorrows and joys in words.

Han Yin brought Du Yingxiong first to visit Shan Huaming's brother-in-law Yu Ning's company. When they met, they inevitably expressed their condolences to his wife Shan Yingchun's murder.Yu Ning thanked them politely, and invited the two of them to sit on the long sofa for welcoming guests.

Yu Ning is obviously thinner than the previous few days, and has a lot more gray hair. He looks a little depressed. Although he has cheated on him and even thought about divorce, after all, after all, he is a married couple with a hundred days of grace. There is still a certain degree of love between husband and wife in Yingchun.After the secretary served the tea, Yu Ning sat on the side sofa and brought up the case: "Both of you are here, is there any progress in Yingchun's case?"

"Sorry, it's still under investigation!" Han Yin said with an embarrassed smile, "How much do you know about your brother-in-law Shan Huaming's social circle?"

"What's wrong with Hua Ming?" Yu Ning looked surprised and said ambiguously, "Although this kid is stupid, especially in recent months because of the house, he often comes to the house to find trouble and quarrel, but he will not kill his own sister. Bar?"

"You only need to answer the questions. This is our working procedure. Anyone can be the subject of our investigation." Du Yingxiong continued without humility.

"Okay then." Yu Ning nodded hesitantly, and then said simply, "The people Hua Ming usually contacts are his cronies, but I can't tell you the specifics. In fact, Yingchun, her father, and this My younger brother’s relationship has always been relatively weak. We have been married for more than ten years. Except for the New Year’s holidays, she can count the number of times she goes back to her mother’s house during the rest of the time. She is not even willing to let me have contact with them. This is because his father was hospitalized with cancer last year. Yes, Yingchun often goes to the hospital to take care of them, so I have more contact with them."

"Why is the relationship between their family so cold?" Han Yin asked following Yu Ning's words.

"I don't know too well, but I just heard from Yingchun that her father was too partial to her younger brother when she was a child, and often punished her because of her younger brother's faults, which made her feel shadowy!" Yu Ning sneered, with a look of indignation Helpless, "Besides, her younger brother is out of tune, with all kinds of problems, smoking, drinking, and especially likes to gamble. He has ruined all the family's money, and Yingchun is out of sight and out of mind. I just mentioned the house. You must have understood, but in fact, the father-in-law was worried that the brother-in-law would also export the house, so he left a will for the siblings to share the property equally."

"So that's the case!" Du Yingxiong interrupted again, paused, and brought the topic to the point, "Think about it carefully, among the people Shan Huaming knows, is there anyone who is older and has a higher level of education, especially Are you someone who likes to write?"

"My father-in-law likes to write diaries! Even though he is just an ordinary instrument worker, he also went to college in a serious way." As soon as the hero finished speaking, Yu Ning said without thinking, "Every time I go to At my father-in-law’s house, I can see him writing in front of his desk! Also, there is an old-fashioned wooden cabinet next to his desk, which is always locked. By chance, I happened to pass by when he opened the cabinet. Seeing many diaries with kraft paper covers in them, I asked him what was recorded in them, and he said with a half-smile: 'It's just memories that are not worth mentioning!'”

"Diary?" Du Yingxiong and Han Yin glanced at each other quickly, and asked anxiously, "Where are those diaries now, do you know?"

"It's burned!" Yu Ning looked at the two of them inexplicably, and said casually, "On the first seven days, Hua Ming burned them all in front of his father-in-law's graveyard. There were more than ten copies. Hua Ming said that his father-in-law has been writing all his life." If you like it, just burn it to him, so as not to worry about it. I asked at the time if I read what was written on it. Hua Ming said carelessly, whoever has the time to read that crap, probably the old man wrote some crap poems. Sour words or something!"

"Is there really no one left?" Du Yingxiong asked.

"I probably didn't keep it! The cabinet is an old item, and it's worth a lot of money. I heard that it was secretly sold by Hua Ming a while ago. He even sold the cabinet, so he can still keep those old diaries? Because of this, Yingchun He was furious: "What a loser, if you want money, sell the cabinet to me, after all, it's your own family!"" Yu Ning was angrily counting, when the phone on the table rang, he subconsciously looked at the two of them. With a glance, he intentionally wanted them to avoid it for a while, but he was too embarrassed to say so, so he hesitated, "Well... Shall I answer the phone first?"

"Oh, you pick it up and you pick it up, we just went out to get some air, let's talk after you pick it up!" Han Yinming said logically, standing beside him.

"By the way, does your lover have the habit of wearing a red scarf around his neck?" After walking a few steps, Du Yingxiong suddenly turned around and asked a question that had been asked many times before.

"No, I have tied it once in a while, but there is no red one." Yu Ning froze in mid-air while picking up the phone, and the answer he gave was exactly the same as that of the family members of the previous victims.

The two of them had just left Ning's office. Seeing no one on both sides of the corridor, Du Yingxiong couldn't wait to pull Han Yin to the ventilation window on one side of the corridor and said, "Mr. Han, I feel more and more that Shan Xiongye is too suitable for our criminal side." I wrote it, even the analysis of the diary is the same as yours, but it was a pity that Shan Huaming burned it. Do you think it is possible that this kid actually read the diary? Or Shan Xiongye brought a diary with him during the hospitalization. Did Zhao Liang accidentally see it? Of course, this question is based on the assumption that Shan Xiongye is the murderer. Could it be that the DNA comparison made a mistake?"

"Certainly not." Han Yin shook his head like a rattle and said, "It was done by you, Gu Zu, do you think there is something wrong? But what you said earlier is a good idea, let's temporarily confirm that the murderer is Shan Xiong Ye, then tell me, Zhao Liang and Shan Huaming have read the diary, and what is the motive behind taking Shan Yingchun as the ultimate murder target?"

"Shan Huaming's is really confusing to me. He read his father's diary, why would he kill his sister? And Zhao Liang's seems to be easier to explain, so let me talk about him!" Du Yingxiong thought for a while and said, "If he learns from the diary that his patient is actually the enemy he has been looking for for many years, then using his own way to deal with him and killing his daughter is a very revenge method to relieve hatred. As for the other three The crime was committed, just like what you analyzed earlier, it was because we were worried that we would discover the intersection between him and Shan Yingchun, so we deliberately set up an obstacle. By the way, if the murderer is Zhao Liang, it would make sense if there is a marking behavior." Du Yingxiong specially said Looking up at Han Yin, he tentatively asked: "About this point, don't be angry if I tell you."

"If you have any ideas, just say it, when did it become so boring! When no one has made a mistake, it is normal for me to make mistakes. We have to accept it humbly for the sake of the case!" Han Yin seemed to be talking about himself, In fact, it is also implying that the hero should not be obsessed with his previous mistakes, and encourage him to untie that knot as soon as possible.

"Okay, let me say!" Du Yingxiong was obviously encouraged and said confidently, "I think you have overlooked a more important marking information in the whole case handling, that is the piece of red cloth tied around the victim's neck. Previously, we thought it might be the habit of wearing red scarves by those who were angry with the murderer, but several family members and even Yu Ning denied this, so I wanted to unravel the true meaning of this symbol, so I carefully studied the red scarves. I found that it is actually the same as the red scarf worn by elementary school students. Combined with my analysis above, because his parents died early, and his sister brought up Zhao Liang with one hand, the scene of his sister tying the red scarf for him may be deep in his memory. When he wanted to take Shan Yingchun as the target of revenge, wearing a red cloth strip around her neck, which meant a red scarf, meant to punish her and her father on behalf of her sister."

"No, the red cloth strip is also part of the murderer's plan to destroy. Why would Zhao Liang want to destroy his sister?" Han Yin pushed the frame on the bridge of his nose with his index finger, his eyes flickered, and it seemed that the small universe in his brain to solve the case was about to Outburst, "The direction of the red scarf seems to be correct, but... it should point to Shan Huaming!"

Before the words finished, Han Yin had already turned back to Yu Ning's office and "broke" in directly.Yu Ning seemed to have just put down the phone, when Han Yin walked to the table and asked, "How much do you know about your lover Shan Yingchun when he was young?"

"Ah..." Yu Ning was suddenly taken aback by Han Yin's aggressive aura, and couldn't help but shrink back. After being surprised for a while, she said blankly, "Uh, she told me that when she was young, there was a For a while, I didn't like reading very much, love to play, love vanity and so on, but who doesn't have rebellious time? She has no problem in essence. To be honest, after marriage, she really lived with me sincerely. She can be called a good wife and Good mother!" Yu Ning paused, concentrating, his tone changed, and he said hesitantly, "However, after your questioning, I really feel that something is wrong. You should know that she was born in Baotu City, in She lived there for more than ten years, and she returned to the smelting mine with my father-in-law after her mother passed away. I once asked her about her life experience in Baotu City, but she didn’t seem to like to mention it. Alright, let's change the subject."

"Hmm!" Han Yin pursed his lips, thought for a moment, and then asked, "Dr. Zhao Liang, do you know?"

"Of course, the attending physician of my father-in-law." Han Yin's question jumped from Shan Yingchun to Zhao Liang. Just know each other?"

"Do you know that Zhao Liang's sister was murdered more than 20 years ago?" Han Yin continued to ask along his own train of thought.

"I heard!" Yu Ning said without hesitation, "Once he was chatting with my father-in-law in the ward, and his father-in-law casually asked him about the situation at home, so he started talking."

"Was Shan Huaming present?" Han Yin asked.

"Yes, our whole family is here!" Han Yin said east and west, unable to understand the complete logic, which made Yu Ning even more puzzled, and said anxiously, "What's going on! Yingchun's death and Hua Ming, and father-in-law are involved?"

"Okay, thank you. I'm here today. I'll let you know if there's any progress in the case." Han Yin ended the question decisively, then turned his head to wink at the hero, and the two strode out of Yu Ning's office one after another.Yu Ning still wanted to ask more questions, but they were gone!
No.12 Crime and Punishment
Coming out of Yu Ning's company in a hurry, Han Yin hurriedly called Team Liu and Gu Feifei, telling them to return to the team to meet immediately no matter where they were, and said that they had important discoveries to discuss with them.

When they arrived at the team, Han Yin and Du Yingxiong went straight to the meeting room, where Gu Feifei and Liu team had been waiting for a long time.Facing their anxious and expectant gazes, Han Yin stopped talking nonsense and briefly introduced the situation of the meeting with Yu Ning just now, and then solemnly presented a point of view that in his opinion is enough to solve all the mysteries...

However, as soon as Han Yin finished speaking, Gu Feifei immediately questioned: "Based on the current information, Shan Xiongye does fit the profile of the murderer in the early years, but the relationship between him and Shan Huaming should not be what you said. That. I have repeatedly confirmed the results of the DNA test, and from the likelihood ratio, there is no possibility that Shan Huaming and the murderer in the early years are related."

The confident deduction was immediately denied by Gu Feifei. Han Yin looked calm and seemed not surprised, but before he could explain himself, Team Liu said: "I really agree with Teacher Han Yin's analysis. , As for the DNA mismatch, is it possible that the problem lies with Shan Yingchun? Could she be..."

"That's right! This will straighten out the whole case!" Du Yingxiong slammed his hands and said excitedly, "Back then, Shan Yingchun refused to cooperate with the DNA comparison because she was worried about exposing the true relationship between her and Shan Huaming; And Shan Huaming came back after wandering around because he had already learned about his relationship with his so-called father and sister, and he knew very well that the test results would not help the case at all!"

"On the contrary, we can disregard the relationship between their family and the case, especially for him to kill Shan Yingchun in the end. He may be lucky enough to think that we have compared his DNA with the murderer's in the early years, and then I won't spend any more time on Shan Yingchun's DNA!" Gu Feifei also agreed with a sudden awakening.

"Okay, everyone knows everything at once, so I won't explain much." Han Yin smiled and said, "Of course, we have to wait for the results of the three-party DNA cross-comparison before we can fully confirm it, but I am very confident of!"

"Then what should we do with Zhao Liang? We checked the surveillance video of the Second Hospital, and we didn't find the so-called person who framed him, but there are too many blind spots in the surveillance, and people who are familiar with the terrain may avoid the cameras...or let them go first... ...But this kid has a motive, time to commit the crime, and solid physical evidence, so it's not appropriate to let him go..." Liu Dui faltered and confused, as if there was something hard to say.

"You are so embarrassed, probably because Zhao Liang has some background?" Han Yin asked tentatively.

"I was detained for domestic violence, and even beat the patient's family members. I am still safe and working in the hospital. Who would believe that he has no background?" Gu Feifei commented on Han Yin's question in due course.

"Since you have all guessed it, let me just say it straight!" Captain Liu sighed, "Although Zhao Liang has a bad temper, his professional ability is still very good, and he is considered outstanding in the entire medical circle of our metallurgy. I'm afraid it's the last time I can be a department director or something. As for the things he caused, other people would have been expelled several times. There are many rich people and high-level leaders in the city among these people. To tell you the truth, since he was brought into the team, there have been many dignitaries with identities who have inquired about him through various channels. The leadership of the Bureau is under a lot of pressure. If he is the only suspect, we will be able to resist no matter how big the resistance is, but looking at it now, he may indeed be framed!"

"Shan Huaming used to accompany Shan Xiongye in the hospital for several months. He must have a good understanding of the hospital's terrain, work system, and Zhao Liang's work and rest time; and by chance, he learned that Zhao Liang was his father's first victim. Brother, and then he thought that Zhao Liang had doctored his father and was beaten by Zhao Liang, so the resentment in his heart can be imagined. So in his carefully planned revenge plan, he deliberately let Zhao Liang be his scapegoat!" Du Yingxiongshun Following Liu Dui's words, he elaborated in depth.

"It should be this kind of motivation." Han Yin nodded approvingly.Suddenly he stopped, his eyes froze for a few seconds, as if he had caught some kind of inspiration, and then he made that familiar movement again, stretched out his hand and pushed the frame on the bridge of his nose, and said faster: "Wait, I thought of it." In addition to the analysis just now, I think Shan Huaming's identity as the murderer can also be identified from the motive. Previously, we could not find the intersection of the victims because we had no contact with Shan Huaming. Just like the hero just now That is to say, if Shan Huaming's whole motive for committing the crime has a certain element of revenge, then would those middle-aged women also be the targets of revenge that he planned from the beginning?"

"That's right! I really overlooked this point. Those female victims all lived in the area where Shan Huaming delivered the express. Maybe they had conflicts with him because of the express." Team Liu patted the table vigorously. Shouted, "I'll send someone right away, no, I'll go to the courier company myself to check the situation."

"Okay, but even so, from a safe point of view, I don't think Zhao Liang can let go for the time being!" Han Yin suggested cautiously.

"In fact, there is another problem that makes the bureau very passive." Team Liu frowned and said, "You young people all know that now is the age of Internet information, such as Weibo, WeChat, there are many things that you want to cover, but you can't cover them. Zhao Liang The news of being arrested has already spread from the hospital to the society, and now rumors are spreading wildly in the society, saying that we are afraid of Zhao Liang's deep background, so we haven't formally arrested him..."

"Then don't let him go in a hurry!" Gu Feifei raised her voice emphatically.

"Oh, I also understand the truth. Forget it, let's ignore him..." Liu Dui waved his hand irritably, and asked Han Yin, "By the way, even if the DNA results and motives are confirmed, they cannot be used as evidence for arrest. , what are your plans next?"

"You are right, there is still no evidence for direct conviction, so I am in a hurry to meet with you, and I want us to discuss countermeasures together!" Han Yinwang said to everyone.

"I guess he should have been shocked by the courier company's investigation and so on, why don't we control him first and interrogate him?" Gu Feifei lowered her head and pondered for a while.

"That's right! Based on his suspicion, we can arraign him in accordance with the law." Du Yingxiong also suggested.

"It's okay to try and interrogate first, but a serial killer like him will not confess easily unless you get all the stolen goods at the scene. Especially our purpose is not simply to make him confess, but also to hope that he can Provide evidence to confirm that Shan Xiongye was the murderer in the early years." Han Yin paused, and thought for a while, "Let's do it this way, the hero and I will go to Baotu City, try to understand their family's experience clearly, and then formulate an effective At the same time, there is another direction, which is also worthy of our in-depth investigation-Yu Ning said that the diary was burned by Shan Huaming in the first seven days, and he started committing crimes a few months after Shan Xiongye's death , but still clearly performed the exact same marking behavior, so I think Shan Xiongye’s diary may not have been completely burned, and the records related to the crime may have been preserved, and Shan Huaming may even be continuing to write!”

"If we can really find this diary, not only can we take the absolute initiative in the interrogation, but from experience, it is very possible to find invisible DNA evidence in the diary." Gu Feifei said.

"Then let's make more attacks. I'll arrange a car right away. You guys should hurry up and get on the road. The team should also seize the time to apply for a search warrant and conduct a large-scale search of Shan Huaming's residence and work unit." Team Liu concluded.

"Then you didn't wait for the DNA results?!" Gu Feifei looked at Han Yin hesitantly, as if he felt that he was too hasty.

"It's okay, let's keep in touch at any time, and you should inform me immediately when the result comes out. Even if you make a mistake, it's just a waste of time on the road. Now that the two important suspects are under our control, no more victims will appear Already!" Han Yin deliberately smiled at Gu Feifei, pretending to be relaxed.

"Be careful on the road." Gu Feifei replied with a warm smile and told her.

Baotu City is more than 900 kilometers away from Smelting City. It is the largest city in the Mongolian Autonomous Region and a heavy industrial city with a similar background to Smelting.There are also rich mineral resources here, and there is also a non-ferrous mining group with a long history that is well-known in China and the world. Before Shanxiong Industry was transferred back to the smelting company, it had been working in a smelting branch of the group.

After more than ten hours, Han Yin and Du Yingxiong finally arrived safely in Baotu City the next morning.At about the same time, Gu Feifei called. Apart from caring about their safety along the way, the more important thing was to inform them of the results of the DNA comparison.Of course, the result was as expected by Han Yin!In addition, in the delivery records of the courier company, Team Liu found out the intersection of the three female victims except Shan Yingchun: Shan Huaming not only delivered the courier for them, but was also separated by the three of them because of his attitude. After complaining, Shan Huaming was fined a certain amount of commission by the company.In this regard, Shan Huaming's pattern of selecting targets has been fully confirmed, that is, all his targets of harm have certain grievances with him.

Subsequently, Han Yin and the local police took over.With the help of some information compiled in the previous investigation, and the local police received a call from the Metallurgical and Mining Bureau requesting cooperation in handling the case, they immediately dispatched their staff to assist in the visit. Han Yin and Du Yingxiong were able to meet some retired old workers of the factory the next afternoon , Several of them even lived in the family compound of a factory with Shan Xiongye, and they knew everything about his family.It can be said that the progress of this cross-provincial investigation is much smoother than expected...

However, Mining City is not so lucky!It should be said that the situation is very bad!
The search and evidence collection against Shan Huaming did not yield any results. Shan Huaming said that he had thrown away the damaged guns and old uniforms. As for the so-called diary, it was even more difficult to find. They all said that they had never heard him mention any diary.What surprised the police even more was that Yu Ning hired a lawyer for Shan Huaming shortly after Shan Huaming was interrogated. , the police confronted him for 48 hours to no avail, so they had no choice but to release him in accordance with the law.

However, Shan Huaming and his lawyers did not want to let it go. They spread news through the Internet media, questioning the police's failure to pursue suspects with solid evidence. Shady, trying to frame the common people, to take the blame for the "deep foundation" Zhao Liang, and said that there will be a further statement in another day!

Shan Huaming challenged the police so confidently because he saw that in the current social environment, the senior leaders and the general public hated and punished the police's fraudulent behavior in the process of handling cases, in an attempt to confuse the public and deceive the public. The masses, who do not know the truth, used the influence of public opinion to push the police into an embarrassing situation.It was a game for him, an act of vengeance to make up for years of being neglected, persecuted and marginalized by society.Of course, in the final analysis, it was because he knew very well that the police had no conclusive evidence against the father and son.

The situation of smelting is urgent. After Han Yin and Du Yingxiong in Baotu City learned about it, they rushed back without caring about the exhaustion of the past few days.The car drove at high speed all the way, and finally returned to the compound of the criminal police detachment of Yekuang City. It was almost midnight, and only one window in the dark office building was still shining. Han Yin knew that it was a conference room.

The meeting room was filled with smoke and the atmosphere was extremely dull.Gu Feifei and Ai Xiaomei had serious expressions; Liu Dui and other key case investigators were smoking cigarettes with frowning faces; sitting in the middle of the long conference table were the two directors of the Municipal Bureau and the deputy directors, both of whom had gloomy expressions , looking very annoyed.

Han Yin and Du Yingxiong nodded to everyone, and sat down beside Gu Feifei and Ai Xiaomei respectively.When Han Yin's butt touched the chair, Gu Feifei whispered in his ear: "A few hours ago, Shan Huaming and his lawyer respectively announced the news through Weibo, saying that tomorrow, no, this time should be said to be this morning At 10:[-], a press conference will be held in the conference room of the office building where the law firm is located, detailing the process of being innocently persecuted by the police!"

"It's really inappropriate for us to announce the progress of our current case to the outside world. It seems that we are bound to suffer from the dumbness!" Team Liu forced a wry smile, and continued Gu Feifei's words.

"What do you say? You told people that Zhao Liang had the motive, the time to commit the crime, and the murder weapon, but he was wronged? You have conclusively identified the father and son as the murderers, but you have no actual evidence. You can't make people laugh when you say it Big teeth? Those reporters have a good question, do you rely on guesswork to solve the case?" The director, surnamed Zhou, glared at Team Liu sarcastically, and asked a series of questions.

"Zhou Bureau, regarding the suspicion of Shan's father and son committing the crime, it should be said that it can be confirmed now, especially the relevant information we obtained from Shan Xiongye's early workers can be compared with the previous profile report... Team Liu looked very embarrassed, and looked at Han Yin as if asking for help, and Han Yin followed the director's words and made a detailed report on the information obtained by Baotushi and his party.

"It's still the same question, where is the evidence, where is the evidence? How can Shan Huaming plead guilty in a short time?" The director's face softened a little, but his tone was still questioning.

"Yeah, once the press conference is held, our Bureau will be put on the cusp of public opinion again. In the past ten or twenty years, because the case has been pending, this kind of questioning and criticism of the Bureau's ability to handle cases has disappeared. There are enough of them, and if we can't give the public an explanation as soon as possible, I'm afraid our police career will be over!" The deputy director at the side said with a dejected expression, not without worry.

The momentum of the two bureau chiefs was so low, let alone others, and the conference room fell into a quiet atmosphere again.Han Yin thought for a while silently, turned his head and looked at Gu Feifei, considered the words, broke the suffocating dullness, and said: "It is very difficult, but it may not be an opportunity! From the performance of the crime, Shan Hua Mingming does have certain crime and anti-investigation capabilities, but it can also be seen that he is much worse than his father in controlling emotions. The seductive actions we made several times on the Internet actually caused him to have a lot of troubles. Strong stress response, if he is not lucky, I am afraid that he will have been exposed long ago! Besides, he is a gambler, aggressive and aggressive, and it is his nature to become more courageous when frustrated. The character of a gambler makes him lose control of his emotions, and may cause him to lose his voice and reveal the truth! So I asked the leader for permission to give me a chance to confront him head-on at the press conference!"

"This..." A gleam of light flashed in Zhou Ju's eyes, but it quickly became chaotic again. After exchanging glances with the deputy bureau and Liu Dui, he stared at Han Yin hesitantly and said, "You have full confidence." Is it? You have to be clear, once it is self-defeating, it will look more like we are slandering Shan Huaming in a targeted manner from the outside world!"

"Zhou Ju, I think you are the one who is confused about the situation!" Gu Feifei, who had held back for a long time, finally couldn't hold back, and said in an aggressive and sharp tone, "In the final analysis, the case is yours. Teacher Han Yin is willing to gamble with the reputation he has built up over the years in order to solve the case. It can be said that he has made a lot of sacrifices, and you are still afraid of wolves and tigers. Don't you think it is too much? Otherwise, you have better Method?!"

Gu Feifei wanted to continue, but Han Yin hurriedly stopped her.Over there, the younger generation ruthlessly defeated the first army's weekly game, his face turned red and white, and he seemed extremely annoyed.Team Liu saw that the atmosphere was not right, so he quickly stood up to smooth things over.He first made a low-profile suggestion to Zhou Ju: "Why don't you let him try?" Then he turned his head and cautiously told Han Yin: "But Teacher Han, you must formulate a complete dialogue strategy here! "

"This is necessary, don't worry!" Han Yin deliberately put a smile on his face, trying to ease the discordant atmosphere on the field.

"Well, it's getting late, and it's only a few hours before the press conference. Go back first, hurry up and work out a specific implementation strategy!" Zhou Ju looked at his watch, and followed Team Liu's words , I found a step down for myself.

"Okay, okay...then let's go back first!" Han Yin responded, and patted Gu Feifei's shoulder lightly, lest she would say something embarrassing Zhou Ju if she was still angry.

Gu Feifei understood Han Yin's kindness, but she didn't accept it. She shook her arms and said in a stern voice to Zhou Ju and Liu Dui: "You don't need to participate in today's operation. It's better to do support outside the office building. The local media all If you are familiar with you, if you are recognized by then, the situation will easily get out of control."

Although Gu Feifei's words sounded harsh, they had to be admitted to be very reasonable. Zhou Ju and Liu Dui could only nod their heads blankly, expressing their approval passively.

At 10 o'clock in the morning, four members of the support team arrived at the press conference on time.The multi-functional meeting room, which is not too big, was crowded by various media reporters. Shan Huaming and his attorney sat directly in front of the reporters, and the long table in front of them was filled with microphones with various signs. .

The press conference was hosted by Shan Huaming's lawyer, and the content was nothing more than embellishment, exaggerating the process of being investigated by the police.The lawyer claimed that repeated unreasonable investigations by the police had seriously interfered with Shan Huaming's normal life, and he even lost his job because of this. He called on the media to uphold justice for him and asked the police to stop persecuting him immediately.In addition, the lawyer also made a very in-depth understanding of Zhao Liang. He listed Zhao Liang's bad deeds in detail to the media, and implicitly pointed out that Zhao Liang was the real murderer...

It can be said that the atmosphere at the scene was extremely warm, with flashing lights frequently flashing on Shan Huaming's face. Although he kept claiming that his life had been disrupted by the police, he did not see much sadness on his face. The time for the media to ask questions, and it is ostentatiously stipulated that only those who click can ask questions.When Shan Huaming looked left and right to choose who to ask questions, Du Yingxiong opened the way in front, tried his best to separate the crowded crowd, and led Han Yin to the front row.

Han Yin's sudden intrusion caused an uproar at the scene, but Shan Huaming held his breath, looked Han Yin up and down, and asked tentatively, "Are you..."

"We are here to congratulate you, congratulations on finally getting what you want!" Han Yin stepped forward, met Shan Huaming's gaze, pointed at the reporters behind him, and said with a contemptuous smile, "This It's the scene you've been looking forward to, right? You want more people to feel your presence, and you want to be the focus of this society. After today, those who once ignored you and dismissed you will turn their attention The focus is on you, and you enjoy having everyone at your fingertips, right?"

Shan Huaming could see that the person was not kind, but he still restrained his emotions and raised his hand to stop the lawyer who was about to question Han Yin. He raised his eyebrows and said with a slightly disdainful expression: "I thought about it, I heard that there is a The criminal psychologist who helped us mine the mine to solve the case should be you, right?"

"It doesn't matter who I am, what matters is that I know 'who' you are!" Han Yin was noncommittal, turned to the reporters and asked, "Do you want to hear me tell his story?"

"Think about it!" "Go on!" "Are you really an expert from Beijing?" "Are you representing the metallurgical police at this press conference?" What do you think of the accusation?"...

As soon as Han Yin finished speaking, the scene exploded.The cameras and video cameras in the hands of the reporters were aimed at him, and they immediately asked various questions.They would never have imagined that the criminal investigation experts from Beijing would directly confront Shan Huaming in this way. This news material is simply too explosive!
Han Yin smiled, ignored the reporters' questions, turned back, stared at Shan Huaming, and asked provocatively, "What about you, do you want to hear what I have to say?"

Shan Huaming shrugged his shoulders at first, looking indifferent, then leaned back on the chair, folded his arms in front of his chest, looked at Han Yin, and made a gesture of confrontation.Han Yin turned his body slightly so that he could not only observe Shan Huaming's performance, but also take into account the reactions of the reporters: "When we talk about your story, I'm afraid we must start with your father, Shan Xiongye, because I have to speak for 1988. seek justice for the eight women who lost their lives in the 5 years between May 2002 and February 2."

"In my investigation, your father is an extremely introverted and taciturn person. He is always immersed in his own spiritual world and is used to expressing his inner feelings and recording life in words. Of course, this does not prevent him from becoming an outstanding talent— ——In 1963, with excellent grades, he was admitted to Baotu Iron and Steel College, a key industrial college in a neighboring province. There he spent four happy years, met your mother, and established a romantic relationship.”

"Maybe it's God's will. Just when your father was preparing to welcome a better life with your mother, a special official document in a special historical period completely disrupted their vision. The central government issued a notice stating that the junior college of that year College graduates no longer enjoy the national cadre establishment, but have to work as farmers and workers at the grassroots level, so your father can only follow your mother and be assigned to a local factory. Studying hard in a cold window and being named on the gold list, in the end it only becomes As a grassroots smelting worker, your father's loss and reluctance are self-evident, and I think he should record this in his diary."

"Life has to go on, and being a worker at that time was also a good job, so not long after you started working, your father and your mother officially married. According to the life of a normal person, after getting a wife, you will have children, but after two years Afterwards, your mother’s stomach didn’t move. Go to the hospital. The problem lies with your father. The sperm survival rate was low. With the medical level at that time, it was tantamount to declaring your father infertile. It’s impossible for a man to reproduce ability, in such a conservative age, one can imagine how humiliated and ridiculed he would be, and your father would also record this inferiority and helplessness in words."

"Subsequently, with the help of the organization, your father and your mother adopted a little girl, your sister. Your father had mixed emotions about her arrival: On the one hand, the family finally looked like a normal family, but at the same time it seems that your father can always see his shameful side. Fortunately, your sister was a very well-behaved and sensible child at that time. An indelible happy time in memory, so many years later, when your sister enters adolescence and becomes a rebellious, decadent, dissolute, bad boy who often plays truant and hangs out with the hooligans in society, your father will not care about it anyway. I can't accept it. The quarrels, beatings, and conflicts between the father and daughter have intensified day by day, and the result is that your sister ran away from home again and again."

"The longest time your sister ran away from home lasted nearly a year. When she came back, she was already a pregnant woman with a big belly who was about to give birth. She gave birth to a little boy within a few days; what's more, she couldn't tell the difference. Know who the child's father is, and of course no one is willing to take responsibility for her. As parents, their teenage child has a child out of wedlock, and the child's father is unknown. What could make them more ashamed! So , your mother, who was already frail and sickly, fell ill when a fire came up, and she was bedridden for several months until she died. In the end, the specific cause was not found out, and the doctor could only explain it by stagnant heart fire, which means that your mother is I'm going to be mad at you by your sister!"

"Since then your sister has become a disgrace to your father again. He must really want to turn back the time and return to the time when your sister brought them happiness. So a few days later, Baotushi was alone at home during the day A 20-year-old young woman was cut into her throat by the murderer, and her body was tortured after her death. The murderer left fingerprints at the scene, which have been kept by the Baotu City police to this day..."

"After your mother passed away, your father had nothing to worry about in Baotu City, and he didn't want to be pointed at by neighbors and co-workers because of your sister's affairs, so under the guidance of your grandfather, he took you My sister and her children were transferred back to work in the smelting mine. It should have been 1988. A middle-aged man in his 40s came to a strange unit and had to start all over again like an apprentice. He had no friends and was surrounded by Putting contemptuous eyes on anyone, the sense of loss is probably unbearable, not to mention that you have lost your wife not long ago, and you have to raise your daughter and her young children. All these troubles have finally made your father completely lost He began to focus his anger on your sister, thinking that it was her depravity that made his life so embarrassing. He needs to control his own destiny, and he wants to make his life easier by eliminating your degenerate sister. Back on track. So from that year onwards, just like the case in Baotu City in the previous year, cases of young women living alone were burglarized and murdered one after another in Yekuang City. Until 2002, the number of victims reached eight There are so many names..."

Han Yin paused for a moment, fixed his eyes on Shan Huaming, and said with emphasis:
"I think what you said just now must have been read in your father's diary when you packed up his belongings after his death. Yes, he is the one who made the whole smelting mine fearful and raped and killed eight innocent women. What makes you even more unbelievable is that you discovered from your father's diaries that his real identity is actually your grandfather, and your sister is actually your mother."

"I can imagine your shock and anger at that moment. The mother you have been dreaming about is close by, but she has not fulfilled even a little bit of mother's responsibility. She is even worried that you will affect her newly formed family. Her husband keeps you at a respectful distance, and even wants to occupy half of your 'father''s inheritance. Looking back on the growth experience along the way, you think that if you have a mother, maybe you won't be called a wild child by other children, maybe you won't If you get tired of studying and leave school prematurely, you may not always be struggling and wandering at the bottom of society. You seem to have found the root of your failure in life. You are full of resentment and anger, and you dream that one day you will be like you Grandpa punished your mother like that!"

"Not long after, you accidentally saw the so-called retired old policeman's Internet post, and you felt the glory of your grandfather from it. You were deeply fascinated by the sense of accomplishment of killing people invisible, blinding the eyes of the world, and calmly manipulating the police, so You decided to get back the bloodthirsty jackknife your grandfather used to take revenge on all those who hurt you. Of course, you are very smart, and you made up your mind to let Zhao Liang be your scapegoat!"

"Speaking of which, I would like to insert a piece of my own experience. When I was very young, my mother divorced my father and went abroad. As for my mother, my deepest memory is probably that when I joined the Young Pioneers, she personally put it on for me. The picture of the red scarf. I think this is a luxury and a hope for you. You have imagined that picture in your mind countless times, so that gradually that scene has become the image of your mother in your memory, so you In the first three crimes, a red cloth strip was tied around the victim’s neck to replace your mother’s identity. Of course, the last time you committed the crime, you are already facing your mother, so there is no need to wear any red cloth Cloth strips!"

Han Yin stopped talking again, looked at the reporters for a few times, then turned his head, and locked his eyes on Shan Huaming's face again, and said: "This is the story, you and everyone present will be able to find out, wearing a The core of the whole story is your grandfather’s diary. You don’t need to deny this, because your mother’s husband Yu Ning has already proved the existence of the diary, and also said that you burned all the diaries in front of your grandfather’s cemetery But I don’t think so, I believe that among your grandpa’s many diaries, there must be one dedicated to recording all his crimes, and this diary should be kept by you, it will be the most direct evidence against you and your grandpa evidence of."

Before Han Yin finished speaking, Shan Huaming burst into laughter, spread his hands, and said mockingly: "It's just your speculation!"

"Yeah! Did you make a mistake! What can you say without evidence?" "Is that how your police handle cases?"

Han Yin grinned and showed a sly smile, as if he had expected everyone's reaction.He first pressed his hands at a group of reporters, signaling them to be quiet, then turned his head and approached Shan Huaming, and said provocatively again: "Do you dare to bet with me once?"

"What's the bet?" Shan Huaming asked without thinking.It seems that for a gambler, any gamble can arouse their fighting spirit.

"Believe it or not, if I ask you a few questions, and of course they don't involve the diary, I will know the whereabouts of the diary?" Han Yin said in an aggressive tone.

"Three is three!" Shan Huaming said bluntly, and then asked again, "What if I win?"

"You won. I can formally apologize to you on behalf of the smelting and mining police, and promise not to disturb you again." Han Yin pretended to be sincere.

"If you win, what do you want?" Shan Huaming raised his jaw and asked.

"You don't seem to understand that if I win, the next thing is up to you!" Han Yin snorted.

"Then come on, let's start!" Shan Huaming said confidently.Like all gamblers, they never thought they were going to lose until they started betting.

"Have you been to the library in the last month?"

"no!"

"Have you seen Zhao Liang's locker key in the hospital?"

"no!"

"Before I came to this press conference, I just came back from Baotu City, your birthplace. We learned that your mother conceived you when she was having sex with many men at the same time. The technology in the past couldn't do it, but now we The identity of your father has been confirmed through technological means, do you want to meet him?"

"In no mood!"

After asking the three questions, Shan Huaming seemed to realize that he had been tricked, and said angrily, "You're not looking for a diary at all, you're trying to take this opportunity to humiliate me, right?"

"I was seen through by you, yes, I am indeed humiliating you!" Han Yin spread out his hands and said with a sneer, "Because we have already found that diary, which is in your grandfather's tomb. Your grandfather's fingerprints, and your continued criminal record."

"You..." Shan Huaming stood up abruptly, slammed the table hard with his fist, and the microphone placed on it was knocked to the ground, and then he froze with a pale face, seemingly at a loss for what to do.At this time, the lawyer sitting next to him leaned forward quickly, leaned into his ear, and whispered a few words, Shan Huaming's face quickly recovered, and he sat back on the chair firmly.He lowered his head and pondered for a while, then raised his head with a smirk on his face, and said calmly to Han Yin: "You are right, you are right! I like to be famous and to be valued by others. This diary, and the contents recorded are all done by myself! But so what? My lawyer just told me that the area marked on the search warrant you showed earlier did not involve my father’s cemetery, which is Said that the way you obtained the diary was not legal, and we have the right to ask the court not to disclose the contents of the diary, nor can it be used as evidence in court. Well, your only evidence can no longer be used, no matter what is written in the diary, You can't do anything to me for what I have done. Thanks to you, I should be recorded in the criminal history book, right?"

"It's a little too early for you to be happy!" Han Yin said with a sly look on his face, "I don't know if I didn't explain clearly, or you didn't understand, what I just said was that we 'discovered' the diary, and didn't say' I got the diary, that is to say, I only speculate that the diary is in your grandfather's tomb, and the fingerprints and the so-called continuation are also speculative, but you seem to have just confessed in front of everyone present?"

"Hold your head in your hands, lie down on the table, right now!" Seeing that the fire was almost ready, Du Yingxiong drew out his gun and pointed it at Shan Huaming.Shan Huaming also knew that the situation was over, so he had to obey Du Yingxiong's order.

end
As Shan Huaming explained, his grandfather Shan Xiongye did have a diary dedicated to recording crimes, and he did continue to write it, and then secretly hid the diary in Shan Xiongye's tomb.The police found the fingerprints of the two people in this diary, and the handwriting identification also matched; just as Gu Feifei expected, there were Shan Huaming's dander in the diary, which is the so-called invisible DNA sample; In addition to Shan Huaming's confession, the chain of evidence is complete, and it is completely possible to confirm Shan Xiongye's nine crimes across the two places from 1987 to 2002, and Shan Huaming's four crimes this year...but Shan Huaming no matter what I also don't understand why Han Yin suddenly found out where the diary was hidden?In fact, Du Yingxiong, Gu Feifei and Ai Xiaomei who were present at the time couldn't figure it out either.And the last three questions of betting, Han Yin will definitely not just play tricks on Shan Huaming, he must have intentions, so what exactly is it?

After Han Yin returned to the academy, he revealed the answer in his class:
The core is three words: micro-reaction!The reason why Han Yin made such a lengthy account of Shan Huaming's life experience at the press conference, as well as the ins and outs of his grandfather and grandson's crimes, was simply to find a breakthrough from Shan Huaming's stress response.Throughout the narration, he has been observing Shan Huaming's expression and body language. Of course, Shan Huaming has reacted a lot, so he won't repeat them one by one.What caught Han Yin's attention the most was that when he heard Yu Ning say that Shan Huaming had burned all diaries in front of Shan Xiongye's cemetery, Shan Huaming made a gesture of rubbing his lips with the back of his hand, and then quickly put them on the table. The act of sniffing his nose, in Han Yin's view, may be Shan Huaming's "comforting" stress response when he encounters pressure.

The subsequent bet was actually to confirm the "baseline" of Shan Huaming's fear response, that is to say, to establish his response to stress without any mental preparation.The three questions at that time were all designed, and they all belonged to the "irrelevant and stressful" type of questions.An in-depth explanation is that the three questions have nothing to do with the diary Han Yin wanted to find, but they all put some pressure on Shan Huaming.However, the first two questions were all done by Shan Huaming before. He may have been prepared to deal with such questions in his heart, and the reaction he made may have been designed by him, but the last question is that he completely Unexpected, so he subconsciously rubbed his lips with the back of his hand, and then quickly put it on his nose to smell it.From this, Han Yin further confirmed that the "cemetery" is a place that scares Shan Huaming, so he boldly speculates that it is the place where the diary is hidden.

Of course, even if the police find the diary from the cemetery, with Shan Huaming’s fingerprints and notes on it, it can only prove that Shan Huaming has read and written the diary. If he resists and refuses to admit the murder, the outcome will be unpredictable .So, just as Han Yin said before the press conference, he will use Shan Huaming's combative and gambler character to provoke him, so as to induce him to admit the crime...

Han Yin told his students about the case in class, and gave answers to related doubts. After hearing it, the students discussed it below, and their words were open:
"God still has eyes. That man named Shan Xiongye raped and killed so many women, and the retribution was on his testicles. He got testicular cancer. In the end, the victim's brother cut his balls with his own hands. Isn't this retribution?" A female classmate said carelessly.

"Oh, I'll go, you're too uninhibited, you're still a young and beautiful girl, screaming balls, balls, I'm blushing." A few male students next to me laughed.

"Get out, you can't pretend to die!" the girl said, beating the boy.

"But there is some truth to it. Fate is really hard to say. Although Shan Xiongye escaped legal sanctions, he did not escape the torture of cancer, and he would never have imagined that his grandson would kill his own son. Mother! Especially for Shan Huaming, it seems that this is his fate, and he can't escape it even if he wants to!" A female student sitting in the front row said calmly.

……

Standing on the podium, Han Yin watched silently the discussion of the students below, feeling a little emotional in his heart: "Sometimes, fate is actually just an excuse for the losers and the angry to give up on themselves, just like what Voltaire said: 'It doesn't matter Destiny is nothing more than a test, punishment or compensation.'People can't choose their origin, they can't choose their appearance, but they can definitely choose between good and evil!"
