People can be domesticated!

wedge
North, coastal city, Mingzhu City.

In June, there are no clouds in the sky, the sky is blue and transparent, and the city with moderate temperature and temperature is densely covered with high-rise buildings, bustling with crowds, and it is a scene full of vitality.

However, just as the bright sunshine cannot penetrate every corner of the earth, behind the bustling city, under the cover of bright high-rise buildings, from time to time there will be a few devastated buildings that have been abandoned for many years, which is the so-called unfinished building.As for the reasons for the unfinished project, it is nothing more than the broken capital chain of the developer, the deep debt quagmire, the construction violation or the poor quality of the project, which was ordered to suspend work, etc.

In the southern part of Mingzhu City, there is such an unfinished residential project called Harvest Garden, which almost accounts for all the reasons for the unfinished projects listed above. Shang, has never turned salty fish over, and now it can be called the most famous unfinished building in the city!
Today is a rare good weather, and Harvest Garden has also welcomed a rare popularity.

A group of people walking on the construction site were almost all wearing blue trousers and white shirts - the standard attire for government employees. The faces surrounded by the crowd looked dignified. No need to ask, they must be city leaders. The purpose of this trip is not difficult to judge, it should be to prepare for the subsequent clean-up of unfinished building projects in the city.

It rained a few times a while ago, and the dirt road on the construction site was a bit muddy. In addition, it had been inaccessible for many years, so that the ground was overgrown with thorns, and the weeds were as high as knees.But what made them even more unbearable was the pungent stench in the air, which seemed to be the rotting smell of rats or other dead animals.

Seeing the frowns of the leaders, the discerning subordinates hurriedly winked at the subordinates with lower positions, and several young staff members dispersed, sniffing their noses like puppies, sniffing around. , Sniff, and look around for the source of the smell...

After searching for a long time, without any results, a young man accidentally fell into a ditch covered by weeds beside the dirt road.The ditch was more than one meter deep, and the young man fell so suddenly that he fell hard; what's more, there was a big iron bucket lying in it, and the young man's head hit the edge of the bucket, causing him to scream in pain .

After finally getting up in embarrassment, the young man looked embarrassed and kicked the iron bucket angrily.With the muffled sound of the iron barrel, a more intense stench than before suddenly burst out, making the young man feel that the source of the stench seemed to be right in front of him.He hurriedly bent down and picked the weeds around him. First he saw the cement fragments scattered around the mouth of the barrel, and then he saw a human head with black skin and rotten flesh!

Directorate General of Criminal Investigation, Serious Case Support Department.

The recent changes in Gu Feifei are obvious.The original short hair was a little longer, and it was trimmed into a fashionable mid-section bob. The color and style of the clothes are more beautiful and enchanting. For example, today is a wine red V-neck shirt with a bow tie, matched with a gray slim fit Trousers, elegant and intellectual, full of noble temperament.In terms of personality, it seems to subtly become more gentle with the outside, restraining the aggressive posture, and the attitude of communicating with others is not so cold, and sometimes even greets colleagues when they meet on the road.Perhaps this is the magic of love. In the face of love, no matter how tough a woman is, she will become soft.

Of course, when facing the old leader Wu Guoqing, she still maintained her usual solemnity.She respectfully took a case file from the frowning Wu Guoqing, and after opening it, she saw:

On June 6 this year, the police received a report from the masses. In a long-abandoned factory building on the outskirts of the city, the police in Mingzhu City found a large iron bucket filled with cement and sealed the mouth of the bucket. There was a naked female corpse in the bucket. According to the records of the missing person report, Zhang Cuiying, a 1-year-old hotel owner, was identified; four days later, on June 66, when the leaders of the Mingzhu Municipal Government were inspecting a local construction site of an unfinished building, they found a car that was also sealed with cement. A highly decomposed male corpse was found in a large iron barrel. The forensic autopsy confirmed that the victim was nearly 6-year-old Jiang Qingshan.

Seeing that Gu Feifei closed the file, Wu Guoqing seriously exhorted: "I did some research on Jiang Qingshan's situation. He has a certain influence in the local criminal investigation circle, and most of the current leaders of the criminal police detachment were trained by him. Therefore, they should be more eager to solve the case, and they will inevitably be impatient and reckless. In addition, public opinion is more disgusted with the behavior of government officials enjoying privileges. When the female boss was killed, we didn’t ask about it, but when the victim’s identity became the former head of the criminal police team, we paid enough attention. Therefore, whether you are facing the local investigators or the media, you must pay attention to your words and deeds, and have an appropriate attitude. So as not to cause unnecessary conflicts and affect harmony."

"Don't worry, I know what's in my heart." Gu Feifei solemnly replied, "If the timing is right, I will explain to them—the reason why we took on this task is because of the homogeneity of the criminal pattern, such as the method of dumping the corpse." , tool, location, and age group of the victim, etc.”

"Well, I used to be a little nervous before, but I can see all the changes in you recently." At this age, Wu Guoqing treats the subordinates around him as his own children, and the children can be happy and happy. Of course he was the most gratified, and at the end he did not forget to joke, "I should thank Mr. Han Yin, right?"

"Why are you thanking him..." Gu Feifei lowered her head and trimmed the ends of her hair, twisted it, then raised her head, and said with a little sadness, "Actually, it's not entirely true. It's just one aspect of being with him, and more of an epiphany about life. Right! As a forensic doctor, death and corpses are so familiar to me that I never seem to really think about what death means to a person and the people around him. Only when the dead body was my colleague who was with me day and night, and my comrade-in-arms who fought side by side, did I truly feel the unprecedented shock brought to my soul by the end of life.' Taiping case (see the fourth volume of the second season )'Three colleagues sacrificed, and Du Yingxiong also walked before the gate of hell. The moment I stood in front of the operating room, I was really uncomfortable, and I kept asking myself in my heart: Why don't you cherish the time with these colleagues? What? You obviously care about them, why can't you treat them better on weekdays?"

"Xiao Gu, you're enlightened, I'm so happy to hear you say that." Wu Guoqing felt even more relieved, "Of course it's important to be happy while you're alive, but in fact, when you make the people you care about happy, you will be happier! "

A police academy in the north, a lecture hall.

Every class of Han Yin has a case discussion session. The case he presented to the students today is the "Heyang Yang Slave Case" that shocked the whole country.

"In September 2011, the police in Heyang City successfully cracked a vicious detention case. The criminal was a local man surnamed Li in his early 9s. The criminal dug a basement and transformed it into a cellar, and imprisoned six women as his sex slaves. And forced them to engage in pornographic activities such as online video chatting and prostitution in reality, and imprisoned the victims for up to two years, during which time two women were even tortured and killed by him, and buried on the spot."

"However, what puzzled many case investigators was that the rescued female victims did not show any resentment towards the perpetrator. Protect the criminals; what is even more incredible is that the investigators found from the transcripts of these victims that they not only did not resist during their imprisonment, but were jealous and jealous of each other in order to please the criminals, even if they had the opportunity to escape They don’t take advantage of it, or even help the evildoers to torture and kill their ‘disobedient’ companions together with criminals.”

"As for the prison site, the so-called cellar, it took a year to build. It was hidden at a depth of six meters underground. First it passed through a three-to-four-meter-deep shaft with a ladder, and then passed through a nearly five-meter-long shaft. Only Hengjing can enter the cellar. In the meantime, he has to go through five iron gates with locks. The cellar is less than 20 square meters in area and about two meters high. It is divided into two floors with wooden boards at a distance of more than one meter from the floor. On the top is a bed. There are liquefied petroleum gas tanks, gas stoves, kettles, computers, etc. In addition to video naked chat performances, the computer cannot access the Internet at other times, but you can play games and watch DVDs. Electricity is connected from the outside, and daily necessities, food and water are provided by Criminals are transported in from outside from time to time..."

As evidence photos related to the imprisonment case flashed on the projector screen, Han Yin restored the details of the case in detail.The students sitting below began to whisper to each other, and a heated discussion ensued.After a while, Han Yin began to ask questions: "What I just introduced is a typical case with 'hostage complex' factors. In the past, we focused more on analyzing the criminal's psychology in class, but today's discussion focuses on the victim's psychology. Which one Can students tell me what factors caused the victim to suffer from hostage complex in this case?"

After Han Yin's voice fell, the classroom was silent for a few seconds, but soon there was a scene of enthusiastically raising their hands to speak.Han Yin glanced around, and raised his hand to a girl wearing glasses, and the girl raised her hand to support the frame and said:
"I think judging from the characteristics of criminal behavior, the criminal has a power-seeking personality, so relatively speaking, his desire to control will be stronger, and he will make the victim clearly feel that he is in control of everything in that cellar God, especially life and death. The most intuitive example is that if he does not bring in food and water for a few days, the victims will die soon. Therefore, the victims will feel very clearly that their lives have been seriously affected. Threat. I believe that should be a factor."

"Anyone else want to talk?" Han Yin smiled at the girl with glasses, noncommittal, then turned to ask others.

Then a fat boy was selected by Han Yin. He said eagerly: "I think it is because of the victim's complete despair. Because the cellar is hidden very deep, and there are many iron gates separated, the victim must have Knowing that no matter how much they cry for help, people outside will not hear them, so they gradually give up their resistance and self-esteem, and in order to get better treatment for themselves in that environment, they turn to cater to criminals."

"I think there should be a little more." A boy sitting in the front row rushed to say without waiting for Han Yin to signal, "Just like what the female classmate said just now, criminals should especially enjoy the feeling of controlling the situation, so he may Some methods will be used, such as giving some small favors to a certain obedient victim, so as to arouse the jealousy or yearning of others, and at the same time show them the benefits of cooperating with him, and then seize the opportunity so that everyone can get some favors, So that those victims can actively move closer to him."

"Is there anything else to add?" Han Yin nodded with a smile again, and then looked at the others.

This time, a boy sitting at the back got a chance to speak. His voice was loud and he seemed very confident. He said: "I think 'brainwashing' must be indispensable. Because the victims are isolated from the world, the information they can access The source of the crime is only the criminal, and the criminal is good at controlling, of course, he will not miss such a brainwashing opportunity. For example, he will confuse the information, making the victim feel that although they have been missing for a long time, no one cares outside, no one is looking for them, This will arouse the victim's resentment towards the outside world, making it easier to accept him; for another example, he may continue to tell or show stories and videos related to sex slaves to the victim, and slowly let the victim recognize the value of this behavior Normalize and generalize, so that the victim can completely accept this perverted behavior from the bottom of his heart; moreover, he may paint a particularly bright picture of the profit prospects brought by obscene and pornographic services, and destroy the victim's conscience through profit-driven And reason. In short, in the end, those victims will completely lose the ability to think and be at his mercy without complaint."

In fact, at this point in the discussion, the answer Han Yin wanted was ready to come out, and after looking at it, it was almost the end of class, so he signaled those students who still wanted to express their opinions to put down their hands, and then concluded: "The opinions of these students just now are very good. The four characteristics are indeed often seen in hostage complex cases, and most of the time they will appear together..."

Before Han Yin finished speaking, the mobile phone placed on the desk vibrated suddenly, and Gu Feifei's incoming call was displayed on the screen...

In the second quarter, the troops are divided into three groups
Gu Feifei met the chief prosecutor—a young female forensic doctor Dai Jingxi in the forensic department of the criminal police detachment of Mingzhu City. She pointed to the two corpses on the dissection table and introduced:

"When the old captain Jiang Qingshan's body was found, the corruption was quite serious. It is estimated that he had been dead for more than 10 days, that is, he was killed around May 5; the cause of death is relatively clear. Death due to epidural hematoma; no other superficial trauma, internal organs, liver fluid and blood tests showed no abnormalities."

"The female victim is more complicated. Although the body was discovered earlier, the time of death was a little later than that of the old captain. When it was discovered, the rigors had basically eased, and the cornea was completely cloudy. She had been dead for almost three days, and the time of death was around May 5. The face was severely beaten, there were multiple contusions on the body surface, the subcutaneous bleeding was very serious, and a large number of blood clots were deposited on the back, but no tissues, organs and large blood vessels were ruptured and bleeding, and the sternum and left ribs were fractured to varying degrees. Blood tests showed that The concentrations of essential amino acids and non-essential amino acids were greatly reduced, and the concentrations of tryptophan and cystine were even more significantly reduced. Symptoms of organ disorders appeared, no obvious fatal injuries, and no signs of sexual assault were found, so all in all... "

"It was a traumatic shock death caused by extensive soft tissue damage!" Gu Feifei followed Dai Jingxi's words and concluded, "Combined with signs of anemia and malnutrition, it is estimated that he was illegally detained for a long time and then tortured to death!"

"That's right, I think so too." Dai Jingxi sighed incredulously, "I don't know who has such a big enmity with the old lady and treats the old lady so cruelly."

"Yeah! It's unimaginable!" Gu Feifei shook her head, forced a wry smile, took two steps forward, and approached Jiang Qingshan's body.Since the corpse was already highly decomposed when it was discovered, the forensic doctor had to cook it to remove the rotten flesh before conducting further examinations. Therefore, the so-called corpse in front of Gu Feifei was actually just a human shape made up of a pile of white bones.She stared at the skull that had turned into a skeleton for a while, and said: "The scars are in the shape of a scaphoid, deep in the front and shallow in the back. It should be caused by a vertical blow from the rear with a conical stick. Obviously the murderer is..."

While Gu Feifei and Dai Jingxi were exchanging information about the autopsy, Du Yingxiong and Ai Xiaomei knocked on the door of the victim Zhang Cuiying's home in a high-end residential community in the center of the city. Zhang Cuiying's two daughters, Wang Yiwen, received them. and Wang Yanjing.

The two were invited to sit on the sofa in the living room, and took advantage of the time when the sisters were making tea and serving water to look around. The house is a duplex structure, and the living room looks extraordinarily open. The modern and luxurious decoration is bright, stylish and extraordinary. It is not difficult to imagine that this family is very rich financially.

After working for a while, the two sisters sat down on the side sofa. They didn't know whether it was because they were nervous or they had a very harmonious relationship with each other. They were very close to each other.The eldest sister, Wang Yuwen, waved her hand towards the coffee table, made a gesture of "please drink tea", and asked with a hint of surprise in her tone: "We have already told you the police before what should be said, I don't know what else you want to know?"

"We are from the General Bureau of Criminal Investigation. We have just taken over the case, so there are some things I still want to hear from you." Ai Xiaomi explained politely, "In order to find out the truth about your mother's murder as soon as possible, you don't mind saying it again, right?"

"I don't mind, I don't mind, just ask whatever you want." Different from her elder sister who looks shrewd and capable, her younger sister, Wang Yijing, is completely a virtuous young woman at home, and she said sincerely while shaking her hands in a hurry.

"Have you two sisters been living with your mother for so many years?" Du Yingxiong immediately asked.

"Oh, no. My father passed away two years ago, and my mother always said she was afraid to live alone, so we moved in to accompany her." Wang Yuwen replied, "My sister and I divorced a few years ago, and the children are not around. Anyway, I am alone in my own home, why not just live with my mother and take care of each other."

"When was the last time you had contact with your mother?" Ai Xiaomei asked.

"As far as the day she disappeared, it should be May 5." The two sisters looked at each other, and finally the plenipotentiary of the sister Wang Yuwen said, "That morning, after breakfast, at about 29 o'clock, my sister and I went to work in the hotel, and then I never saw her again. The two of us searched all night but couldn’t find her, so we went to the police station to report the case early on the 9th!”

"Before your mother disappeared, did you have any abnormal behavior?"

"No, it's normal to eat, sleep, talk, etc."

"Is there anything missing in the house, especially about your mother?"

"A few pieces of clothes that she usually likes to wear are missing, and all her gold and silver jewelry are gone, and we haven't found the 3 yuan that was kept at home as a spare." Wang Yuwen paused, as if suddenly remembering something, He added, "By the way, she always carries a few bank cards with her, and the total amount of money in them is more than [-]."

"From the perspective of the two of you, who do you think is more suspicious?" Ai Xiaomei asked again.

"It must be Qu Xiaojun." The two sisters said a name at the same time, with annoyed expressions and words, and looked at each other again.Then it was Wang Yuwen who answered: "Qu Xiaojun was the store manager of our main store and worked with my mother for many years. My mother liked him very much and took care of him everywhere. But then my father passed away, and he always came Talking with my mother at home to relieve boredom, I don’t know why the two of them have a bit of “that meaning”. Come on, that Qu Xiaojun is not yet 40 years old, can he fall in love with my mother? He is clearly trying to cheat money and sex! My sister and I think it’s a sign No, thinking that they must completely cut off their contact, they simply fired Qu Xiaojun. So my sister and I thought that maybe he contacted my mother again somehow, and then killed him after cheating money!"

"When was he fired?"

"end of last year."

"Do you know what Qu Xiaojun did after that?"

"I don't know."

"Can you tell me about the itinerary of the two of you sisters for the whole day on the 29th?" Worried about causing misunderstanding, Du Yingxiong explained again, "This is our routine procedure for handling cases, you don't mind."

"We were all in the restaurant that day. In the evening, my younger sister came back to cook for my mother. She found that she was not at home, turned off her mobile phone, and found that those things were missing. If she felt something was wrong, she would notify me immediately. I took the staff in the store and started looking around. As I said just now, I searched for one night, and the staff in the store could testify until the next morning when I reported the case.” Wang Yuwen recalled a little.

"Okay, we will understand." Ai Xiaomei took out a pen and a small notepad from her pocket, "By the way, please tell me more about Qu Xiaojun's situation, including his home address, his The mobile phone number you have used, the colleagues you usually hang out with, etc..."

"It's no problem." Wang Yanwen said, picked up the phone and began to look for the phone number.

Du Yingxiong got up at the right time and pretended to ask casually, "Can I see your mother's bedroom?"

"This..." As if they were not mentally prepared for Du Yingxiong's request, the two sisters looked at each other hesitantly before Wang Yujing stood up, seemingly reluctant, but deliberately concealed, "Come with me, mother After she's gone, neither of us sisters dare to enter her room."

Du Yingxiong followed Wang Yanjing up the wooden ladder to the second floor. Wang Yanjing pushed open a door next to the stairs, pointed inside, and signaled Du Yingxiong to look casually.

The bedroom is dominated by white, the bed, bedside table, wardrobe, dresser, ceiling chandelier, etc. are all white, and the whole room looks clean and dazzling at first glance.

Du Yingxiong looked around inside, with a relaxed expression all the time, and did not observe much in a certain position, giving people the feeling that there is actually nothing to pay attention to in the bedroom.But when he said that he could go out, the moment Wang Yanjing turned around, he quickly reached out and wiped the table top of the dressing table, and then felt a thick layer of floating dust on the palm of his hand...

Han Yin and Zhang Hongsheng, the head of the criminal police detachment of Mingzhu City, visited the home of the old captain Jiang Qingshan. Jiang Qingshan's only son Jiang Wenbin deliberately took time out of his busy schedule to wait for the two at home because they had greeted them in advance.

The nearly forty-year-old Zhang Hongsheng is actually Jiang Qingshan's old subordinate. He can achieve today's achievements thanks to Jiang Qingshan's support all the way. Of course, he has a relatively close relationship with Jiang Wenbin, who is about the same age. When we met, after introducing Han Yin, we didn't exchange too many greetings before directly cutting to the point.

"I checked your report record. It was on June 6. At that time, your father should have been missing for a long time. Why did you wait so long to report?" Han Yin asked.

"Speaking of this question, I'm really really guilty..." Apparently the pain in my heart was pierced by Han Yin's words, Jiang Wenbin's wise and confident face just now was full of embarrassment, he paused, and stretched out his hand to Zhang Hongsheng to ask for it. I lit a cigarette, took a few puffs, and then continued, "My wife and I jointly run an environmental protection company. Recently, we have been preparing to go public in the United States. Negotiating and negotiating with relevant departments day and night, I really neglected to take care of my father. I hung up a call on his mobile phone, but he turned it off, and I didn't think much about it. I couldn't contact him until I returned home. Only then did I hang up the phone with Brother Hongsheng."

"It's not all Wen Bin's fault," Zhang Hongsheng continued, smoothing things over for Jiang Wenbin, "Actually, since his aunt passed away, Wen Bin has always wanted Team Jiang to move in with him so that he can take care of him, but Team Jiang lives and dies. If you don’t go, it’s useless to do any work, and he doesn’t even want to hire him a nanny. He has no choice but to let his temper go. In addition, Wen Bin and his wife are very busy, and sometimes it’s okay to neglect contact for a while. normal."

"Anyway, I'm not a good son." Perhaps some images of his father's life suddenly appeared in his mind, and a smile appeared on Jiang Wenbin's face, "My father belongs to the kind of person who can make troubles. It always made me feel uneasy, but now that I think about it, it’s quite pleasant. He served as a soldier in his teens, was demobilized and transferred to the Public Security Bureau. He has no culture, has a reckless personality, and has a stubborn temper. Wearing a police uniform. You said that you are retired, so you can dance, keep fit, play poker, play chess, etc. with the uncles and aunts in the community in peace. Work, so Hongsheng didn’t dare to answer his phone.” Jiang Wenbin patted Zhang Hongsheng’s shoulder next to him, smiled and continued: “I don’t get along well with the uncles and aunts around me. Choking up, I can’t afford to lose in a game of cards, and I can’t afford to overturn people’s tables. In the end, no one wants to talk to him, which makes the old man very pitiful. Later, I encouraged him to learn to go online, saying that he can play poker online without dealing with people. Playing chess and watching movies. After talking about it a few times, he became a little tempted. I arranged for people from the company's computer department to choose a computer with a large screen and high configuration for him, and I also sent someone to teach him at home for a while. Not to mention, he really put his heart into learning, he learned well, he was quite addicted, and he really stopped a lot.”

"Did he have any enemies with anyone during the period before he disappeared?" Han Yin continued to ask after listening to Jiang Wenbin's emotions patiently.

"I haven't heard him mention it." Jiang Wenbin said bluntly.

"Is there any unusual behavior or request?" Han Yin asked again.

"Probably not..." Jiang Wenbin hesitated for a moment, then suddenly raised his voice and said, "By the way, after the May Day holiday, I visited him at home once before I went on a business trip to the United States, and he asked for a camera with a camera function. I didn’t think much about a better smartphone, and I ordered my secretary to buy him one the next day, I don’t know if this counts as the abnormal behavior you just mentioned?”

"Hmm!" Han Yin nodded, pondered for a while and said, "By the way, you just mentioned the computer, can I take it away and let the technicians look for clues inside?"

"Of course. In my father's case, if you have any needs, I will try my best to cooperate." Jiang Wenbin said sincerely.

"Okay, that's all for today. No matter what you think of, you can contact me at any time." Han Yin got up, took out a business card and handed it over.

"This is my business card. It's not just about the case. If you need my help, just ask." Jiang Wenbin also returned a business card.

Afterwards, Jiang Wenbin locked the door, and the three of them walked out of the community together.Jiang Wenbin drove away after saying goodbye, and Han Yin sat in Zhang Hongsheng's car.Zhang Hongsheng put the computer case in the trunk and got on the car, but for some reason he was not in a hurry to start the car. He was silent as if struggling to think, then turned his head for a while, blushed, and said to Han Yin hesitantly: "There is something , After much deliberation, I think I should tell you, in fact, I also have to bear some responsibility for the death of the old captain..."

The third section summarizes the case
In the evening, the meeting room of the detachment.

The summary and analysis of the preliminary case begins with sorting out the autopsy as usual.Gu Feifei first used a projector to show everyone several groups of photos of the scars that caused the victim's death, and then introduced the cause of death and the time of death in detail, and then said: "From the shape and direction of the scars, the murderer attacked Jiang Qingshan from behind. The focus is on the left side, indicating that the murderer is left-handed. The cracks around the fatal sunken scar are radioactive, and there is no sign of overlapping, indicating that the murderer killed Jiang Qingshan with a single swing of a club, and his technique was clean and experienced. Look, the killer might have a criminal record."

"The autopsy information of Zhang Cuiying showed that she had been detained and abused for a long time, and was beaten to death in the end. Of course, from a medical point of view, Zhang Cuiying was caused by extensive soft tissue damage, resulting in tissue lesions and necrosis. , which led to acute renal failure until she died of shock. This shows that her death was a relatively slow process, which is what I want to emphasize. Unlike other cases, the time of death of the victim in this case is not equal to that of the murderer. The fatal injury could have happened days or even a week ago."

Ai Xiaomei went on to introduce the background information about the victim Zhang Cuiying: "Zhang Cuiying has been engaged in the catering industry locally for many years, and has owned three medium-sized restaurants named 'Cuiying Old Restaurant' so far. The economy is strong and the life is quite good. Two daughters whose marriages have broken up have lived together for many years. Among the daughters, the older sister is Wang Yanwen, 44 years old, and her son is studying in university in the provincial capital; the younger sister is Wang Yijing, 40 years old, and her daughter is studying in local high school, but mainly lives with her father.

"Judging from the feedback information from the previous visits to Mingzhu, the two sisters followed their mother to run the restaurant business very early. They are kind-hearted, steady and not arrogant. Their colleagues have a very good impression of them, and they have always devoted themselves to assisting their mother. Never competed for fame and power. Until three years ago, Zhang Cuiying felt that she was getting older and her energy was getting weaker, so she decided to retire with peace of mind, and took the initiative to hand over the management of the restaurant to her two daughters—the older sister, Wang Yuwen, was in charge of management with a flexible mind and a strong sense of professionalism; The younger sister, Wang Yijing, is weaker, more delicate, and responsible for managing money. The two sisters have very different personalities, and they complement each other at work, and they manage the restaurant prosperously."

"Based on the above information, the two sisters should not have the motive for committing the crime. The more suspicious one is a person named Qu Xiaojun. The victim's several stores all employ store managers. Qu Xiaojun was the store manager of the main store before. She has followed Zhang Cuiying for many years and has never been married. Although the two sisters spoke vaguely, Qu Xiaojun is actually Zhang Cuiying's lover. Later, their relationship was found out. The sisters worried that Qu Xiaojun came here for the family property, so they Sweep him out. According to the two sisters, their mother took some clothes and all expensive jewelry when she disappeared, and took away the emergency cash at home, plus the money in the bank card she carried with her. Zhang Cuiying At that time, they had nearly 20 yuan on them, so what they meant was that they suspected that Qu Xiaojun had tricked their mother away, and after getting the money, they murdered them."

"If you only look at the superficial information, this is a reasonable inference, but it may also be a smokescreen deliberately set by the sisters! Because their confessions are different from the actual situation." Du Yingxiong took Ai Xiaomei's words and put the question Going deeper, "The two sisters have always emphasized that Zhang Cuiying disappeared on May 5. Before the disappearance, everything was normal. Of course, this is consistent with the time of death. At the same time, they can also provide witnesses who are not at the scene of the crime. But just as Ms. Gu The forensic information introduced shows that Zhang Cuiying was detained for a long time before her death, which is contradictory. Then who is right? Of course it is Sister Gu, because Zhang Cuiying’s bedroom looks clean and tidy at first glance, but it is slightly If you observe carefully, you can find that there is a thick layer of dust on both the surface of the furniture and the bed cover. It is obvious that the bedroom has not been lived in for a long time. In addition, Sister Gu specially reminded that although Zhang Cuiying died in May Around the 29th, but the murder time may have been a few days ago, so the so-called alibi evidence of the two sisters is meaningless!"

"We asked the community property to view the relevant surveillance video, but they responded that because the property owner and the community residents could not reach an agreement on the issue of property fee increases, the surveillance in the community was closed by them without authorization six months ago, so The video cannot be provided. In short, the hero and I feel that there is something wrong with the sisters, but we really can't find their motive for committing the crime!" Ai Xiaomi concluded.

"What do you think?" After listening to the reports of the two little guys, Gu Feifei turned her gaze to Han Yin.

Han Yin was the same as before. When others introduced the situation, he either found a small blackboard, or buried himself in writing notes in his notebook.Hearing Gu Feifei's question, he put down his pen, raised his head and concentrated, and said, "Let me talk about my visit first!"

"There is no sign of breaking into Jiang Qingshan's house, and all the furniture is in order. It is definitely not the first crime scene. In addition, after the body appeared, Team Zhang extensively collected surveillance videos around the scene where the body was dumped. In the footage captured by the camera at the entrance, the Jetta that Jiang Qingshan usually drives was found at about 5 am on May 26. Compared with the time of death, the murderer should be the driver at this time, that is to say, the murderer may be the driver. Jiang Qingshan’s car was used to dump the body, and the Jetta car has not been found yet.”

"As for Jiang Qingshan's son, Jiang Wenbin, I believe it has nothing to do with the case, but Jiang Wenbin provided two pieces of information worth noting: First, Jiang Qingshan was obsessed with computers some time before he was killed, so I brought the host back for Xiaomei to study. See if you can find valuable clues; [-]. Before Jiang Qingshan was killed, he asked Jiang Wenbin to buy him a smart phone, and he specifically emphasized that it should have advanced camera functions. Regarding the second point, my first reaction at the time was, would it be possible? It was Jiang Qingshan who accidentally discovered a certain criminal plan, and he exposed his traces while secretly taking pictures of the criminal, so he was suppressed. It is a pity that the mobile phone has probably fallen into the hands of the criminal, or has been destroyed! But then I The private conversation with Team Zhang proved that my guess has a high possibility."

"No, if the old man really found signs of a crime, why didn't he inform Team Zhang? Aren't the two of them very close?" Ai Xiaomei interjected in surprise.

"That's right, Jiang Qingshan has a kindness to Zhang Hongsheng, and the relationship between the two is extraordinary, but there must be a limit to everything..." Han Yin smiled, nodded, and followed Xiaomei's words, "After Jiang Qingshan retired, he still returned to the team to guide the work from time to time. At the beginning, because he was an old leader, and he gave Zhang Hongsheng face, the whole team could deal with him, but after a long time, people felt bored. Zhang Hongsheng It’s not easy to say anything in person, and it’s an embarrassing situation to be caught between the old leader and colleagues. Fortunately, Jiang Wenbin is a sensible person, and when he realized that his father’s behavior was a bit inappropriate, he had a serious talk with his father several times, and even talked to him. He argued that although the emotional confrontation was unprecedentedly fierce, Jiang Qingshan was finally persuaded."

"But Zhang Hongsheng's troubles didn't stop there. Jiang Qingshan didn't come to the team, but he called him every now and then, asking him what case he had, how the case was going, and how the investigation was progressing... Later, it became even more troublesome. , Jiang Qingshan suffers from menopausal syndrome, and he has a lot of doubts. No one looks like a good person. Zhang Hongsheng often receives his calls to the police, but every time it is a misunderstanding, and as time goes by, he doesn't take Jiang Qingshan's words seriously. Slowly, Jiang Qingshan also noticed Zhang Hongsheng's perfunctory, so he didn't take the initiative to contact him as if angry."

"Of course, leaving aside the level of work, Zhang Hongsheng still misses Jiang Qingshan's friendship. During Chinese New Year holidays or when he is free on weekdays, he will bring gifts to visit him at home. However, during the May Day holiday this year, Zhang Hongsheng did not go to his home because of his busy work. , just made a phone call to say hello. On the phone, he asked Jiang Qingshan how he was doing recently as usual. At that time, Jiang Qingshan responded mysteriously that he was working on a big case. Zhang Hongsheng felt that the old man must be messing around again. He didn’t ask in detail. About a week later—the specific time should be around 5:20 am on May 11, he received another call from Jiang Qingshan. After answering, the old man yelled loudly on the phone, this time I really encountered a big case, which was much more interesting than I imagined. Since Zhang Hongsheng was reporting to the bureau at that time, he hung up the phone after only a few sentences. Later, he forgot that Jiang Qingshan had called... So When I mentioned this experience to me, Zhang Hongsheng was very remorseful and guilty, and repeatedly said that if he could pay attention to the old captain in the first place, he would definitely be able to prevent the old man from showing his own bravery, and he would not have died in a daze."

Han Yin paused for a moment and fell into a brief silence. The rest of the people did not say a word, as if they felt sorry for an old criminal policeman who had made many military exploits and finally ended his life in such a way.A few minutes later, Han Yincai went on to say: "Comprehensive analysis of the characteristics of the case, Jiang Qingshan's death is simple and clear, and it should be a vendetta or an extermination. Under normal circumstances, these two motives have one thing in common, that is, the criminal and the victim are in the society. There is a certain overlap in the relationship, judging from Jiang Qingshan's identity as the "former criminal police detachment leader", the most suspected ones are of course the criminals in the cases he handled!"

"The way of Zhang Cuiying's death indicates that there are many possibilities for her being killed. For example, venting anger, seeking wealth, or the criminal has a sadistic mentality, etc. Since the autopsy report did not show any violation of sexual organs, it is also The last motive can be ruled out if there is no trace of cutting up the corpse. Combined with the range of suspects pointed out in the analysis of Xiaomei and Hero just now—the lover Qu Xiaojun and her two daughters Wang Qinwen and Wang Qinjing, the most likely motive for the crime must be Make money."

"Although the reason that attracted us here at the beginning was the same pattern in the selection of victims and the method of disposing of the corpses in the two cases, after digging deeper, everyone can see that they are completely different in terms of killing methods and criminal motives. Therefore, it is temporarily impossible to accurately determine whether there is any connection between the two cases. However, I think we can try to connect the motives of the two cases and investigate in such a direction——Jiang Qingshan accidentally discovered a criminal case, The victim of the case was Zhang Cuiying. She was illegally detained and tortured. The purpose was to force her to hand over her property, passbook and bank card password. The reason why the case attracted Jiang Qingshan’s attention was that the criminal had a criminal record. They were once arrested by Jiang Qingshan. Therefore, we need to investigate whether Qu Xiaojun, Wang Yuwen, and Wang Yujing have criminal records, if not, it means that they still have accomplices, and we need to find out in the social interactions around them."

Han Yin closed his mouth, nodded slightly at Gu Feifei, and signaled that she would make a summary, and Gu Feifei arranged several directions for the next investigation: "Take a look at Jiang Qingshan's computer and mobile phone call records; fully review the information that Jiang Qingshan personally detected. Case files; release of the assisted investigation report to trace the whereabouts of Qu Xiaojun; investigate the bank card and bank deposit withdrawal records carried by Zhang Cuiying; dig deep into the information of Wang Yuwen and Wang Yujing, and implement 24-hour tracking and monitoring of the two..."

Section [-] Unsolved Poisoning Cases
Jiang Qingshan has a stubborn temper and is not easy to get along with. He doesn't really make many friends. In addition, after retirement, he has no official position and no power, so there is even less interaction with the outside world. Therefore, the frequency of using landlines and mobile phones at home is basically limited to those with relatives. Calls; there are more calls to order meals, which are of no value to the detection of the case.

Ai Xiaomei "dissected" Jiang Qingshan's computer very carefully, and recovered some deleted pictures, text and video data in the hard disk, but found no suspicious points.Fortunately, Jiang Qingshan did not delete his web browsing history, and Ai Xiaomei was able to spy on his Internet footprints from it.However, the limitation is that browsers usually only save browsing records for 20 days by default. The computer login records show that Jiang Qingshan last used the computer on May 5. Pushing forward, the browsing records are only saved until April. 14th.

Although it was only a short period of 20 days, the work intensity was not small. In order to avoid missing any clues, Ai Xiaomei had to read one by one, and it took a whole morning to finally go through all the web pages.She summed it up: Jiang Qingshan, like most older men, likes to browse military, sports, and current affairs news. Out of professional preferences, he pays special attention to some news reports about criminal cases, and the most frequent ones are about "thallium". " page.Ai Xiaomei knows that thallium is a metal element, and its compounds are poisonous. The human body will cause great damage to the nervous system and digestive system after ingestion. Large doses or untimely treatment can lead to death.Related criminal cases, the most famous one is the poisoning case of a prestigious university in the capital in 1994. Since the relevant evidence was destroyed, the truth of this case has not yet been found out, and it has become a rather eye-catching unsolved case. widely reported by the media.

There are various indications that Jiang Qingshan must have inadvertently found a news report on the poisoning case a few years ago, which aroused his great interest.Because from his browsing history, Ai Xiaomei saw several webpages reporting on the poisoning case, and he saved them in the favorites of the browser; at the same time, Jiang Qingshan also searched and browsed some popular science about the thallium The webpage, including the preservation of thallium, symptoms of thallium poisoning, thallium sulfate and thallium trichloride and other scientific introductions to compounds containing thallium... and all this happened at the end of April and the beginning of May, and Ai Xiaomei couldn't help but feel that This may be what Jiang Qingshan called the "big case" to Team Zhang!But what is not clear is whether he wants to simply do some research, or is he secretly preparing to investigate the truth of the unsolved poisoning case?

In addition, Ai Xiaomei also discovered from historical records that Jiang Qingshan searched and browsed the official websites of Mingzhu University of Technology and No. Neurology web page.It is believed that Jiang Qingshan's interest in these two units must also be related to the thallium element, but it is not known whether he has had substantial contact with the school and the hospital.

After listening to Ai Xiaomei's analysis, Han Yin felt a little unbelievable. With Jiang Qingshan's experience in criminal investigation for decades, he should be very clear about the difficulty of investigating the unsolved poisoning case—it was almost an impossible task.So analyze rationally, he may just want to do some data collection and research out of interest.But the question is, what exactly did he discover in the process that would lead to his death?Han Yin decided to follow in the footsteps of Jiang Qingshan's investigation to find the answer to the question.

There are more than 30 institutions of higher learning in Mingzhu City from the first to the third, among which the most famous Department of Chemistry is the Pearl University of Technology.Han Yin thinks that Jiang Qingshan browsed the website of the chemistry department of the school specially, maybe he wanted to see the situation of the main person in charge of the department and make some preparations in advance for future visits.Later, with the assistance of the school security department, Han Yin met the head of the department directly and confirmed his guess just now.

"Oh, it's the police again? You came to me some time ago, and you also want to ask about the thallium element?" Seeing Han Yin showing his police officer ID, the dean of the department, who looked like he was in his 50s, was surprised and raised the question. Jiang Qingshan's visit.

"Is this the person you are talking about?" Han Yin took out a photo of Jiang Qingshan and asked the head of the department to confirm.

"That's right, that's him!" The head of the department pointed to the photo and said, "He said his surname is Jiang. He used to be the head of your criminal police detachment. Now he's retired, but he's still working as a consultant in the team."

"What did he ask you?" Han Yin did not expose Jiang Qingshan's "consultant" status.

"I asked a few simple questions." The head of the department blinked and recalled, "He asked if there are any compounds containing thallium in our laboratory, and I said of course there are; then he asked who is there?" I can access it, I told him that almost every major in the department has experimental courses, so teachers and students in the department can probably access it; finally he asked whether the access to thallium element compounds is strict, I said that in recent years The requirements are very strict, there is a special person to manage it, and you must register to receive it, but it was more casual in the past, and it was easy to get it. I asked these three questions, and then he left. Why, is there a problem with his identity? To be honest, although He didn’t show his ID, but I seem to have read the news report on interviewing him in the newspaper, with photos attached, which is very similar to him, so I received him.” The dean of the department finally added.

"It has nothing to do with his identity. As for other things...we have discipline, so I can't tell you in detail. Anyway, thank you for your cooperation." Han Yin hesitated for a moment, and then urged, "Please also keep our conversation secret, so as not to Spread it to the society and cause unnecessary panic!"

"I understand this!" The head of the department replied sensiblely.

After leaving the University of Science and Technology, Han Yin rushed to the No.1 Civilian Hospital of Mingzhu City without stopping.

Just like before, he also went straight to the Department of Neurology and found the director of the department, but this time it was not as smooth as before. The director of the department denied that Jiang Qingshan had visited, and said that he did not know Jiang Qingshan at all.

Han Yin came out of the director's office and walked in the corridor while talking to himself: "It stands to reason that since Jiang Qingshan has gone to the University of Science and Technology, he should also come to the hospital. Isn't he looking for information on the person in charge of the department when he browses the website of the Department of Neurology?" , but because there are people he has dealt with here?"

While lowering his head to ponder, Han Yin heard giggling around him. He turned his head and glanced at it. It was a few nurses in the nurse's station who were chatting, and one of them couldn't help laughing because of some unknown topic.He turned back, took out Jiang Qingshan's photo, and asked the nurses, "Have any of you seen this man?"

"I haven't seen it... I haven't seen it..." Several nurses shook their heads and said in front of the photo.Han Yin was a little disappointed, and was about to take back the photo, when one of the young nurses suddenly pointed at an older-looking nurse who had just walked into the nurse's station and said, "We all work shifts, and we may not always be there. Sister Zhang is in Changbai class, you can ask her."

After hearing what the little nurse said, Han Yin quickly stretched out the photo, and the nurse called Sister Zhang took it, looked at it carefully, then looked at Han Yin suspiciously, and said cautiously: "What are you doing? What are you doing?" Inquire about this person?"

When Han Yin heard this, there was a door, and he quickly showed the police officer's certificate: "I am a policeman, have you seen him?"

"Yeah, around the beginning of May, this person came to Keli to look for the old director Feng Bing, and I happened to meet him. I told him that Director Feng had retired. He looked very surprised and didn't believe me, saying There is still a photo of Director Feng on the hospital website, and I explained to him that Director Feng retired two months ago, so the hospital website has not been updated yet!" Sister Zhang immediately relaxed when she saw that Han Yin was a policeman. He continued, "Then he said he was Director Feng's old friend, but he hadn't contacted him for many years. He wanted to see Director Feng, and asked me for his phone number and home address. I think the old man looks quite decent. , not like a liar, just tell him."

"Then please write for me too." Han Yin pointed to the small notebook and pen.

Sister Zhang quickly tore off a page from the small notebook, handed it to Han Yin after writing it, and said with a sentimental expression, "Director Feng couldn't be found even when I gave you the address. He passed away, and we all attended the memorial service! "

"What? He passed away!" Han Yin looked surprised, couldn't help raising his voice, and raised the photo of Jiang Qingshan in his hand, "Is it before or after this person came to inquire about him?"

"After that." Sister Zhang replied.

Han Yin said goodbye to a group of nurses, went to the personnel department of the hospital, and asked Feng Bing about his work performance.According to the personnel department, Feng Bing has worked in the hospital for nearly 35 years. He is a decent person with outstanding skills and has a good reputation among leaders and colleagues... Afterwards, Han Yin expressed his gratitude to the personnel department for their cooperation, and before leaving I asked a question about how long the hospital keeps medical records. The personnel department said that the outpatient medical records will be kept for 15 years, and the inpatient medical records will be kept for 30 years.

Walking out of the hospital gate, Han Yin paused for a few seconds, then took out his mobile phone and called Team Zhang.Firstly, for him, a foreigner, residential areas are not as easy to find as public places like hospitals and schools. If Team Zhang guides him, he can save time; secondly, he feels it is necessary to communicate with Team Zhang face to face. The situation involved between Jiang Qingshan and Feng Bing.

Soon Team Zhang drove to the hospital to pick up Han Yin, and it didn't take long for the two to find Feng Bing's home.

It was the babysitter who opened the door. The two were let in after revealing their identities. They saw Feng Bing's portrait hanging on the wall beside the living room.Feng Bing's wife's hair was a little disheveled, her face was haggard, and she crouched on the sofa. She seemed to be still immersed in the grief of losing her husband. He heard the little nanny say that the two were policemen, so he managed to cheer up and sat up.

In order to avoid disturbing the old man too much, Han Yin handed over Jiang Qingshan's photo, and asked straight to the point: "Has this person ever been to your house?"

"Oh, I've been here, I think it was probably before May [-]st!" Feng Bing's wife took the photo, picked up the reading glasses from the coffee table in front of him, put it on, took a closer look, and said hoarsely.

"Could you please describe the situation at that time in detail?" Captain Zhang interjected.

"I opened the door for him that day..." Feng Bing's wife turned her head and stared at the portrait on the wall, gradually lost in memory, "He said his surname was Jiang, and asked me if Lao Feng was at home. At that time, Lao Feng was in the study. He probably heard us talking, and came out by himself. The man saw Lao Feng, greeted him warmly, and reported his name, but I don’t remember the details. Seeing that Lao Feng was standing still and didn’t recognize him, he hurriedly He then reminded that he used to work in the criminal police team, and had dealt with Lao Feng several times many years ago. Lao Feng looked at it for a while, nodded and said that he had some impressions, so he asked the man to sit down and ordered the babysitter to make tea, but the man immediately He expressed that he wanted to talk to Lao Feng alone, so Lao Feng took him to the study. After about half an hour, the two of them came out, and the man said goodbye to me and left."

"Did you not explain anything when you left?" Han Yin asked.

"Let me think about it...it seems like I said something..." Feng Bing's wife frowned and thought hard for a while, "Yes, when Lao Feng sent him to the door, he turned his head to Lao Feng and said in a low voice, I can't say the exact words, but it probably means that he just came to confirm something, and Lao Feng didn't have to worry about what happened after that. Later, I asked Lao Feng why he came, and Lao Feng responded lightly. , saying that he came to ask about a former patient, and it has nothing to do with our family."

"Did Director Feng's mood change after that?" Han Yin asked again.

"It seems to be a bit depressed, but I'm not sure if it has something to do with the Jiang coming to the house." Feng Bing's wife explained in detail, "It rained a few times at that time, and Lao Feng once went out without an umbrella and was caught in the rain. It was watered, caught wind and cold, and I didn’t feel good intermittently, so my spirit was not very good; in addition, my son proposed to quit his job as a civil servant and start a business partnership with a friend at that time. Old Feng disagreed and felt sulky , I also suffered from coronary heart disease. Then, about a week later, Lao Feng suddenly died while reading a book in the study, and he was sent to the hospital but was not rescued. The doctor said it was acute myocardial infarction..."

Coming out of Feng Bing's house, as soon as he got into the car, Team Zhang asked, "What do you think of Team Jiang's visit this time?"

"I think that the problem was simplified before, and I thought that Jiang's visit to the University of Science and Technology and the neurology department of the hospital was to learn some information about thallium. , so Team Jiang was actually going after Feng Bing. From this point forward, maybe the Chemistry Department of the University of Science and Technology is also a clear goal." Han Yin replied without hesitation.

"Since this is the case, based on the previously known information, the next key is to find out the "thallium element", "Department of Chemistry, Science and Technology University", "Feng Bing", plus the crimes that you think may have an intersection with Team Jiang. The line connecting people'. But as far as the current situation is concerned, only Feng Bing can do it." Team Zhang concluded.

"So you need to apply to your superiors for permission to fully review the cases that Feng Bing was in charge of as the attending doctor!" Han Yin suggested.

"No problem, I'll do it right away." Team Zhang paused for a moment, and then continued, "Judging from what Feng Bing's wife described when they met, if a certain case is the central point, it should be many years ago." It's gone."

"Yes, that's right!" Han Yin nodded in agreement.

Chapter [-] The Mysterious Villa
This morning, Team Zhang presided over a regular meeting in the conference room of the criminal police team to collect investigation information.

Since its establishment, it has repeatedly solved strange cases, and the Serious Case Support Department has won wide acclaim in the public security circle, and the support team led by Gu Feifei is even more famous. Therefore, when cooperating with local units to handle cases today, the other party will basically handle the case. Control is given to the support team.

Just like the task at hand, Gu Feifei instructed Du Yingxiong to follow up the case of Zhang Cuiying's murder in an all-round way, and was responsible for formulating the investigation plan, arranging the direction of the investigation, and coordinating with the local investigators.Du Yingxiong is currently investigating the victim's lover and two daughters.He made the following report on relevant progress:
"Qu Xiaojun's situation is as follows: he is a foreigner, his hometown is Guangtian City, a neighboring city, and he has no criminal record. After being fired, he returned to his hometown in Guangtian for a period of time. There has been no news. We have asked his family members to notify the police immediately if he contacts his family, and we also ask the local police station to closely monitor his family’s movements.”

"Zhang Cuiying's two daughters, Wang Qiwen and Wang Qijing, have not behaved abnormally since they were interrogated. The two have no criminal records, and basically have no contact with their ex-husband after divorce, and their relationship is still blank. Most of the sisters usually stay in the head office. I often go to various branches to inspect, basically all my energy is spent on restaurant management, which also highlights the abnormality of the two of them for a period of time a few months ago-according to some clerks in the main store, after the Spring Festival, there was so much For a while, the two sisters suddenly didn't show up, and they didn't even call. They didn't show up in the store until a week later. But there was a strange phenomenon, during that time, the two of them always appeared alternately. The explanation given was that Zhang Cuiying was ill and had to be taken care of by one person at home. And Zhang Cuiying has never been to the restaurant since the Spring Festival. Although she handed over the management of the restaurant to her two daughters in the past, she occasionally came to the restaurant Come and sit here. However, all three restaurants have store managers. After years of running-in, they have formed a mature management system. More will be added later.”

"Financial aspects: Zhang Cuiying's mother and daughter have withdrawn large sums of bank deposits under their respective names many times in the past two or three months. So far, their respective savings have been very small. The situation is quite abnormal. I asked the two sisters about this, and the explanation given was, They are preparing to open two more branches, which are larger than the three existing ones. They are currently being renovated and require a lot of capital investment. After verification, the situation is true. However, the bank card that Zhang Cuiying carried with her has not been traced. Extract the records."

Ai Xiaomi is still in charge of what she is good at:
"The mobile phone card that Qu Xiaojun used when he was working in Mingzhu City is a local calling card. If you go to work in other places, the cost of using this card is too high. It must have been abolished by him, and it has been out of service for more than two months. But sorting out According to his previous call records, he had frequent calls with the victim Zhang Cuiying, and the two should indeed be lovers."

"Because Wang Yuwen and Wang Yujing run restaurants, they have contact with all aspects of society. They have a wide range of communication and complex social relationships. Therefore, the frequency of mobile phone use is very high on weekdays, and it is difficult to screen them one by one. But I found a strange Since mid-February this year, the number of times the two used their mobile phones has decreased sharply. For almost a week, that is, the time when the hero said they did not show up in the store, there was no call record. It was not until early April that they gradually Back to normal."

"Of course, as far as the investigation of the call records is concerned, this is not the most critical discovery. I remember that Team Zhang said that he received a call from Team Jiang around 5 am on May 20. The base station is not in the area where Team Jiang usually works, but on a mountain about 11 kilometers away on Linhai Road. I asked our local colleagues and they said that the mountain is called Shuangtai Mountain, and there are several high-end villas around it. Community."

Then it was Gu Feifei's turn to say:

"In Team Jiang's case, Mr. Han Yin sorted out four key pieces of information - the unsolved case of thallium poisoning in a university in the capital, the Department of Chemistry at the Pearl University of Technology, Feng Bing, the former director of the Department of Neurology at No. 1 Civilian Hospital, and his acquaintance with Team Jiang unknown criminals with criminal records. Of course, on the surface they have no intersection, but if you look at them from another angle and time point, you will find that everything seems to be caused by the unsolved thallium poisoning case. However, this case It happened in the capital thousands of miles away, so I believe that what caught Team Jiang’s attention, or inspired Team Jiang, was mainly the criminal pattern of thallium element poisoning.”

"Currently, the University of Science and Technology has denied that any abnormal incidents related to thallium have occurred. At the same time, the No.1 Civilian Hospital has also clearly stated that it has never received a case of thallium poisoning since its establishment. But this is just their one-sided statement. We are still reviewing the case files that Feng Bing has received as planned, and the case files handled by Team Jiang are also reviewing in detail, but the workload is too heavy, and it may be difficult to get results in a short time."

"In addition, Team Jiang's car has been found. In a barren valley in the suburbs, the car was burned. The combustion accelerant was gasoline, and all traces of the crime were destroyed."

Then everyone's eyes focused on Han Yin unsurprisingly, because he could always clearly point out the direction of investigation that needs to be focused on in the next step amidst the chaotic clues.Han Yin also habitually concluded:
"Based on the information we have so far, there are doubts about Wang Yuwen and Wang Yujing. If Qu Xiaojun is really what they said, he cheated their mother of all their money and killed them, then Qu Xiaojun will definitely take all the bank that Zhang Cuiying carried with him. card, but in fact there is no such thing, so Qu Xiaojun may just be a pawn used to divert the attention of the case.”

"Actually, Wang Yanwen and Wang Yanjing showed their flaws at the beginning, that is, they strongly emphasized the time to meet their mother for the last time. The hero also mentioned before that, judging from the situation at home, Zhang Cuiying has actually been away from home for a long time. This is also in line with our forensic judgment, so why did they insist on 'May 5'? To a large extent, they are smart, which shows that they know that Zhang Cuiying stopped breathing on that day, and they know that the forensic doctor will eventually get The same death time, of course, this is cleverness being mistaken by cleverness."

"There is also the issue of the phone call records of the sisters mentioned by Xiaomei. It is worth pondering. For businessmen, it is unimaginable that they have not answered or called in a week. The biggest possibility is that they turned off their phones intentionally; and With the mobile phone turned off, the mother and daughter also disappeared from everyone's sight; when they came back and everything returned to normal, the sisters began to prepare to open a new store with great fanfare. Then connect these abnormal factors with Zhang Cuiying's death , it seems that it can only explain one problem: there is a very big conflict between the mother and daughter, and the core of the conflict is probably 'money'!"

"Regarding this question, let me extend my interpretation: Qu Xiaojun and Zhang Cuiying's lover relationship can now be confirmed. Is it possible that Zhang Cuiying, who is in her 60s, was bewitched by her boyfriend Qu Xiaojun, who is 20 years younger than her, and gave birth to a gift Qu Xiaojun's idea of ​​a part of the property made the two daughters furious, and Zhang Cuiying was obsessed with it, so the sisters simply chose a certain place, detained Zhang Cuiying, cut off all contact with the outside world, and tortured her until she gave up. So far as all the property rights have been released? And the two of them appeared alternately in the hotel later, it may also be because there must be someone guarding Zhang Cuiying somewhere to prevent her from escaping. Of course, her death may have been caused by accident. Then they will launder the money by opening a branch. Otherwise, based on their years of experience in the restaurant business, they should be very clear that the country is vigorously advocating thrift. It is definitely not a wise move to choose to expand aggressively at this time. Therefore, Wang Yuwen and Wang Yujing must be watched to death, and their investigation must be deeper. If necessary, they can be formally summoned to the team to observe their performance under high-pressure interrogation!"

"Let's go back and talk about Team Jiang's case. I thought about it just now. This case must not bypass the thallium element, but I think the University of Science and Technology and the hospital may not have deliberately lied, and Team Zhang has never heard of the team handling the case. There has been a case of thallium poisoning, and since Team Jiang insisted on seeing Feng Bing, it means that the problem lies with Feng Bing. There may have been a case of thallium poisoning in this city, but because the victim was sent to the hospital, Feng Bing misdiagnosed or He was bribed to cover up the real cause of death, and our police investigation was not deep enough at that time, which resulted in the murderer successfully escaping the legal investigation. However, after many years, Team Jiang, inspired by a news report, remembered that Therefore, we have to adjust the direction of consulting cases and case files, and focus on suspected thallium poisoning cases or suspected poisoning cases.”

"In addition, the issue of Team Jiang calling Team Zhang on Linhai Road is worthy of in-depth investigation. Since he was so impatient to explain the seriousness of the so-called big case, it means that he may have suddenly discovered some guidelines for handling the case at that time. clue……"

At the regular meeting just now, Team Zhang seemed very calm, basically focused on listening, and rarely interrupted, but when the meeting ended, he couldn't even attend to lunch, so he couldn't wait to grab Han Yin and rush to Linhai Road. After all, he cared most about The most important thing is the plot related to Jiang Qingshan, and I want to find out the truth about the murder of the old captain as soon as possible.

Linhai Road, as the name suggests, is close to the sea, located at the southernmost tip of the city, surrounded by mountains and sea, with beautiful scenery, it is the most expensive residential area in the city.The villa community is mainly distributed on the west side of this road, consisting of hundreds of townhouses and nearly a hundred independent villas, belonging to two real estate developers. There is only a vertical road in the middle, and the left side is called Wanfu The villa on the right is called Spring City. Han Yin and Team Zhang happened to be in the same community, and they brought their photos to the security guards to identify them.

"This old man has been here before, and chatted with me a few words." Unexpectedly, it would be so smooth, the little security guard of Wanfu Villa recognized Jiang Qingshan in the photo at a glance.

"When did he come?" Han Yin asked excitedly shaking the photo.

"Oh, I can't remember, it seems that I have been here more than once, and asked me about Building 35 in Area C." The little security guard scratched his head and said.

"What's the situation in that building?" Han Yin put away the photos and asked a step forward.

"It's an independent villa, near the fence on the west side of the complex. I don't know who lives there." The little security guard thought for a while, then pointed to the depths of the complex, "Why don't you go to the property and ask, As for the small yellow building, that old man also went to the property that day."

"Alright, thank you!" Han Yin waved his hand at the little security guard, then took out his mobile phone and called Team Zhang, "I found it, come here, I'll wait for you at the gate of the community."

Not long after, Team Zhang arrived, and the two reunited and went to the property to find the property manager of the community.

The property manager introduced himself as Sun, and also said that he had never seen Wang Yiwen and Wang Jingjing, but he identified Jiang Qingshan, saying that Jiang Qingshan had come to the property on the morning of May 5.At the request of Han Yin and Team Zhang, Manager Sun led them to the villa at No. 20 in Area C.

Through the locked black lacquered iron gate, the two saw that it was a European-style two-storey detached villa with a courtyard, surrounded by white walls, and in the middle of the courtyard was a road paved with brown square bricks. The path leads directly to the gatehouse; next to the gatehouse is a garage, the white automatic door is tightly closed; the sparse lawn on both sides of the path is half a foot high, and it seems that it has not been mowed for a long time; two pomegranate trees are planted in the yard And an ornamental tree with big leaves, the branches and leaves are covered with mud, and the windows of the villa are also covered with a thick layer of dust... In short, it seems that no one has lived in it for a long time.

"Are you familiar with the situation of this family?" Captain Zhang asked.

"I'm not too familiar with it, I just know the general situation. The people living in our community are either rich or noble, and they are all people with status. If it is not necessary, as the property owner, try not to disturb the residents. The owner of this house is relatively easy to deal with. Yes, I had a few brief chats when I came to the property to do business." Manager Sun explained the reason for the lack of contact with the residents, and then introduced, "The owner's name is Liu Xun. It is said that he and his wife used to do coal business together. He doesn't like to do anything anymore, so he specializes in stock trading at home. There are four people in the family including him. There is an old mother in her 70s who seems to have a bad lumbar disc and a stroke, so she is paralyzed on the bed; A daughter in her 20s who doesn’t have a serious job and hangs out in the society all day long; there’s also a babysitter.”

"This house has been abandoned for a while from the outside, but the keyhole on the door is very clean. Obviously, someone has opened the door with a key recently. Do you know when the owner moved out, and who has been here recently?" Han Yin He pointed to the keyhole on the iron gate and asked.

"I didn't pay much attention to it, but it feels like I haven't seen this family for more than a year." Manager Sun opened his mouth, but didn't make a sound, looking hesitant to speak, and said after a while, "I'm telling you guys. I didn’t mention our community environment and hardware and software facilities, but we northerners are actually not suitable for living in seaside villas. They can’t stand the humidity at sea, especially in winter. It is much colder than apartment buildings. So the occupancy rate of the community was okay at the beginning, but gradually some people moved out. Anyway, rich people don’t only have this house; some people move out in winter and come back to live in summer. In short, it is idle The villas are familiar to us, and we don’t pay special attention to them.”

"Then have you paid the property fee, water, electricity and gas fees for this house?" Team Zhang asked.

"The last time when your old comrade came to ask, I checked it out. He had paid the property fee in advance for several years. The water, electricity and gas are all charged by the card, and the bank will collect it." Manager Sun explained very comprehensively.

"Oh, thank you!" Han Yin and Team Zhang looked at each other, and said to Manager Sun, "You go back first, we will find you if there is anything to do."

After sending the property manager away, the two touched their ideas.

"There must be something strange in the villa, otherwise Team Jiang wouldn't be so interested. The timing is also right. He called me the other day and said that he encountered a big case. He must have learned the basic information of the villa with the property manager. Maybe His death is also related to the people who lived in the villa recently." Team Zhang said first.

"It should be like this." Hearing Team Zhang's words, Han Yin couldn't help looking up at the villa again and said, "The problem is that the people haunting the villa are the original owners or someone else?"

"Anyway, since there is a door key, at least it has something to do with the original owner." Team Zhang paused, thought for a while, and suggested, "Go back to the property and check the surveillance video. The property should also have the owner's phone number. See if you can contact the owner, if you can't, then you can only apply to your superiors to forcibly enter the villa for inspection."

"Okay, you go first, I'll go around." Han Yin said, glancing at several young girls passing by.

Section [-]: Hiding the Corpse Underground
The monitoring facilities of Wanfu Mountain Villa are relatively well installed, and the public areas in the villa can basically be covered, but unfortunately, the video storage time is only seven days.According to normal reasoning analysis, if Jiang Qingshan or Zhang Cuiying were killed in the villa, then the murderer would definitely choose to escape when the bodies of the two were found and widely reported by the media.Now it is mid-June, and Team Jiang's body was discovered on June 6. Obviously, there should be no images related to the murderer in the seven-day video.But just to be on the safe side, Team Zhang still made a copy and brought it back for Ai Xiaomei to take a closer look.

As for Liu Xun, the owner of Building No. 35 in District C, he registered his ID card and mobile phone number at the property, and checked his account information along the ID number. It shows that Liu Xun is 48 years old and has a 22-year-old daughter named Liu Yao; further investigation After reading the account change records, it was found that only her mother was alive and she was 78 years old... After dialing the mobile phone number, it showed that it was out of payment. Ai Xiaomei checked carefully and found that the last call record of the mobile phone number dates back to January last year. , Did you change your phone number?

With doubts, Ai Xiaomei further sorted out Liu Xun's call records, and found that there were two numbers that had more contact with him during that time: one whose real name was registered under Liu Yao's name, that is, Liu Xun's only daughter, This is normal; the other number is a temporary card, and the call records are limited to Liu Xun, which is suspicious. It seems that the number holder contacted him premeditatedly, and at the same time tried his best to avoid being traced in the future.

Afterwards, Ai Xiaomei got in touch with some callers in Liu Xun and Liu Yao's phone call records, and those people almost agreed that they had not contacted Liu Xun and Liu Yao for quite a while; The witness traced the financial situation of Liu Xun's father and daughter, and the results showed that the father and daughter emptied their bank deposits from February to March last year, and all the funds in Liu Xun's stock account were also transferred out, totaling more than 2 million yuan. As rich as you can imagine.

The problem became serious. The father and daughter stopped using their original mobile phone numbers almost at the same time, cut off contact with friends, and transferred deposits. The family suddenly disappeared, which cannot but be suspected.Either they have done something shady, or they may encounter accidents, and will all this have something to do with that mysterious mobile phone number?
Maybe that mysterious number came from a woman!
After Han Yin broke up with Team Zhang, he took a few steps to catch up with a group of young girls who just passed by. Judging from their attire, they were a bit plain compared to the atmosphere of the high-end community, and they either held young girls in their hands. Children, either lead a pet dog, presumably they are nannies, and maybe go to a leisure square to enjoy the cool at this time.

Han Yin knew that the babysitters were often well-informed in the community, so he called them softly from behind, and the girls turned around in response, looking at Han Yin warily with strangers, but they did not show any particular rejection. the meaning of.This probably has something to do with his handsome looks. He is bookish and gentle, and he doesn't look like a bad guy. Using the current classification of handsome guys on the Internet, he is a bit Korean handsome, but he doesn't have the girlishness of them.

Han Yin showed his ID to show his identity, alleviating the nervousness of the little nannies. He turned his head and pointed to Liu Xun's villa not far away, and asked in a harmonious voice, "Does anyone know who lives in that villa?" See the little nannies Looking at each other without saying a word, Han Yin went on to say: "It's okay, you can say anything you know, doesn't that family also have a babysitter, you should know each other?"

Speaking of the babysitters in that family, the babysitters in front of me began to respond, one of them looked older, smiled shyly, and said shyly: "Her family's babysitters are quite different, and they don't want to talk to us. touch."

"She looks down on people. Sometimes when I meet her on the road, she either lowers her head or turns her face away. I don't understand. They are all babysitters. What's the big deal!" Another nanny pouted angrily. say.

"I think she is very mysterious. I seldom see her during the day. I occasionally use a wheelchair to push an old lady out for a walk. She always wears a sports hat with a long brim, covering almost half of her face; The market also buys vegetables earlier than us, and we are often the ones who go out, and she has already bought the vegetables, as if deliberately trying to avoid us." The little nanny who said this also had a mysterious look on her face.

"It's true that none of you have seen her whole picture?" Han Yin couldn't help interjecting.

"No..." The little nannies shook their heads one after another, but they also said ambiguously, "I feel that they are about the same age as us, in their 20s, and they are relatively taller and thinner."

"Are you asking about his nanny, or about his family?" The short nanny standing in the back row said anxiously without interrupting the conversation.

"Oh, what do you know, come and tell me." Hearing the tone of the short babysitter, it seemed that she knew something about Liu Xun. Han Yin hurriedly let the people in the front row get out of the way and greeted the girl to the front row.

"I'm relatively close to that villa, that's right there..." The short nanny pointed to a villa in front of Liu Xun's villa, "For a while, I remembered that a woman often came to the uncle's house at the back, and the two of them were still holding each other. It feels very intimate, maybe it's his girlfriend or lover." The short nanny smiled sheepishly, and added: "The woman is tall and slender, and she looks very foreign. She always wears big sunglasses and puts a velvet hood on her head. It was normal in winter at that time, but I can’t see what her face looks like. It’s also based on feeling. She shouldn’t be so young, she feels at least It's 40 years old!"

"Do you remember the exact time?" Han Yin asked.

"It seems to be at the end of the year before last!" The short nanny said after thinking for a while.

"When did his family move out?" Han Yin asked.

"I didn't pay much attention." The short nanny paused, and then said at a slightly faster pace, "It seems that someone came back to live a while ago, and there are often rooms with lights at night."

"Did you see anyone?" Han Yin asked after him.

"No, but I saw a car driving into the yard once." The short nanny said apologetically, "I know you must ask me what kind of car it is, I really can't tell, I just glanced at it inadvertently." , It seems to be a dark blue car, which is different from the car that uncle drove before."

"Well, the information you provided is very helpful to us." Han Yin felt that the short nanny really remembered so much, so he didn't want to make things difficult for her, and then politely thanked the little nanny, "You too, thank you Everyone's cooperation."

Based on the information currently available, the mystery surrounding the villa and Liu Xun is even more intense-the little nanny with a secret whereabouts; the intimate "girlfriend" who deliberately concealed her true appearance; the untraceable mobile phone number; The silent new resident; the former captain of the criminal police team who was interested in the villa and died... What is hidden behind all these secrets is really hard to figure out.Could the villa be the first scene where Jiang Qingshan was killed?If you want to solve the mystery, it seems that you must enter the villa!

Later that day, Team Zhang obtained the legal documents for the home search, and immediately brought the on-site investigators from the technical department into the villa.

Surprisingly, the inside of the villa was not covered in dust like the outside of the building. Instead, it was extremely clean. It was obvious that someone had stayed here recently, and it seemed that they had spent a lot of time cleaning up before leaving. Is it intentional to eliminate traceable traces.

The decoration of the villa has a European classical style, and the colors are deep and exquisite.The European-style rectangular ceiling is hung with a candle-style crystal chandelier full of court charm.The walls are covered with coffee-colored striped wallpaper and matched with brown-red wood decorations, which can be described as luxurious, dignified, noble yet artistic and elegant.All the furniture is placed where they should be, and the family photo of the owner of the villa is still hung on the wall, as if they have never left, and still maintain a natural atmosphere of life, but why not clean up the outside of the house?Obviously, some people don't want too many people to know their existence, so everything in front of them is just an appearance, and the next step is to rely on the on-site investigators to reveal the true nature of the matter!
Several surveyors performed their duties: some were in charge of taking pictures, some were in charge of collecting potential fingerprints, some were in charge of looking for hair fibers, and some were in charge of testing blood stains... Of course Gu Feifei would not be idle, she wandered around in the living room After a while, he walked into a bedroom facing south, followed by Han Yin.

The south-facing bedroom faces the sun, with a space of about 30 square meters. There is a large wooden bed in the middle, and a patterned carpet of five or six square meters at the foot of the bed. The furniture and facilities are relatively simple.Gu Feifei walked to the side of the bed and stretched out her hand to press the mattress. No accident, it was hard.The room has good lighting and the mattress is suitable for the elderly to sleep in. This must be Liu Xun's mother's bedroom.

The whole bedroom is clear at a glance, and there seems to be nothing worth exploring, but Gu Feifei doesn't seem to think so.In such a big place, she wandered back and forth, still sucking her nose, as if something unusual was discovered, Han Yin sensed it keenly, and asked, "What are you smelling?"

"The smell in this room is not right." Gu Feifei walked to the bedside and sniffed vigorously.

"What smell?" Du Yingxiong was puzzled.

"It's a smell I'm familiar with." Gu Feifei said in a deep voice, "The smell of corpses!"

"Corpse stinks!" Han Yin's voice was a little louder, a little confused, "Don't talk about the smell, I didn't smell anything!"

Gu Feifei smiled, squatted down suddenly, and picked up a crushed insect corpse from the carpet under her feet, with a smile on her face.

"Is this a cockroach? Why is it still green?" Han Yin leaned over to look at the bug carefully and said, "It looks a bit like a dung beetle."

"This indeed belongs to the same Coleoptera insect as the dung beetle, but it is called the verdant scarab." Gu Feifei corrected, "It is a relatively common insect on corpses, and it mainly appears on corpses or mummy at the end of decay."

"What? Not down here..." Before Gu Feifei finished speaking, Han Yin glanced at the carpet under his feet in surprise.

Gu Feifei pulled Han Yin to the side of the carpet, raised her chin to signal to lift the carpet, and Han Yin rolled up the carpet and put it aside.Sure enough, they saw that there was something strange about the floor under the carpet, and there were obviously large gaps.Han Yin bent down, stared hard at the gap, and hooked his hands in Gu Feifei's direction, and Gu Feifei handed over the flashlight in due course.When Han Yin took the flashlight and shone it along the gap, he suddenly saw two hollow eye sockets and a slightly opened mouth showing ferocious teeth. He was so frightened that he couldn't help taking a few steps back, and staggered to sit on the floor—— Han Yin has never looked at a skeleton so closely and affectionately before!

Chapter Seven
Under the floor of Liu Xun's mother's bedroom, three corpses were found, all ossified. They were placed side by side.

There used to be four people living in the villa, but now there are three corpses, so where are the survivors?Will he be taken away by the assailant?Or is it a murderer at all?Some of the nannies who worked in the surrounding area have testified that the little nannies in the villa acted secretly. In this regard, she is the most suspected of committing the crime, but it is not realistic for her to complete the crime alone.Han Yin couldn't help but think of the mysterious woman who was close to Liu Xun. Could it be that the little nanny and this mysterious woman jointly committed the crime?
Of course, it is too early to draw conclusions. The most important thing is to fully confirm the identities of the three victims. Therefore, after taking a series of evidence-keeping photos, Gu Feifei escorted the body to the forensic department of the detachment.

Originally, the inspection of the villa was just hoping to find physical evidence related to Jiang Qingshan, but no one expected to find three bones.Team Zhang urgently summoned all the police officers from the technical department and ordered the villa to be turned upside down, every inch and every square meter must not be missed.

There are more than a dozen survey areas in the villa: downstairs there are living room and dining room, two bedrooms, kitchen, utility room, cloakroom, two toilets; upstairs there are two bedrooms, a guest room, a toilet, a study and A video room; there is a garage outside the building...the workload is huge, and it seems that we must be ready all night!

Han Yin walked around the villa, sat on the brown couch in the middle of the living room, turned his head sideways, and looked out the large French windows with empty eyes.At this time, there was only one tail left in the setting sun, and the gorgeous rays of the sun were gradually being submerged by the sea and swallowed by the darkness, until the sea and the sky became one color and fell into the dark night. When Han Yin looked away, an inexplicable desolation suddenly surged in his heart.Perhaps because of this state of mind, the room that made him feel majestic and majestic like a palace just now made him feel oppressed, especially the two beige columns standing on both sides of the opposite fireplace, which looked so obtrusive. For some reason, a picture of Jesus being crucified suddenly appeared in my mind!And suddenly he had an inspiration, and another picture appeared in his mind, Jiang Qingshan was tied to the column and was hit in the head...

Shocked, Han Yin quickly left the sofa, took a few long strides and came to the side of the column.Sure enough, there were marks on the cylinders on both sides that seemed to be rubbed by ropes to varying degrees.He hurriedly waved to a nearby surveyor, then pointed to two cylinders, signaling the surveyor to spray the luminol reagent in the nearby area.After about 30 seconds, they saw specks of blue fluorescence - a reaction to blood stains!

At two o'clock in the morning, the forensic dissecting room was still brightly lit, and three dissecting tables lined up with bones were lined up. The slender figures of Gu Feifei and young forensic doctor Dai Jingxi swayed in front of the stage from time to time.After seven or eight hours of continuous fighting, the autopsy results and various test data were basically released, and Han Yin and Zhang team also walked into the autopsy room at this time.

"What's the matter? Can you confirm your identity?" Captain Zhang asked in a urging tone with his bloodshot eyes open.

"The three corpses are all well preserved, and there is not much difference in the evolution status. They should be placed directly under the floor after death, and the time of hiding is relatively close. The corpses are completely ossified, and ordinary people in the villa have smelled them. There was no peculiar smell, so it can be inferred that the victims died more than half a year ago, and the suspected symptoms of frostbite were found on the bones of one of the victims, which further indicated that the death occurred in winter; combined with the mobile phone calls and financial transfers found by Xiaomei According to the time point information provided, the death time range of the three victims can be narrowed down to between January and April last year. In addition, no clothing fibers were found at the scene, indicating that the victim was naked when he was hiding Yes." Gu Feifei took off her mask and introduced it in a general way.

"The detailed results, let's talk from left to right." Dai Jingxi pointed to an anatomy table on the left hand side, and then reported, "Victim No. 1 has a small overall skeleton, a wide and short skull and a short face, and a low and wide pelvis. , There are bony grooves left by childbirth on the dorsal edge of the pubic symphysis. It should be said that the female features are more obvious; the pubic symphysis surface has obvious degenerative changes, with many grooves and small holes, and tooth loss and wear are also quite serious. The angle formed by the posterior edge of the ramus of the mandible and the lower edge of the mandibular body is 130 degrees, indicating that the victim was over 70 years old. As for the cause of death, due to the lack of test materials, it is difficult to judge, and no external force was found on the overall skeleton. Injury, but there are signs of bone tissue necrosis in the lower limbs, and the bone seam of the left parietal bone of the skull is obviously cracked, and there is no stress around the crack. It is suspected that the content of the skull is frozen and caused by volume expansion. From the professional perspective of Team Leader Gu and me Look, the above two phenomena can be caused by extremely low temperature, especially for an elderly person, which means that we are all inclined to freeze the victim to death. In addition, I also recalled At the beginning of last year, it was indeed extremely cold here, and the weather records showed that the lowest temperature reached minus 15 degrees Celsius, which is rare for many years.”

"Victim No. 2 is obviously male from the large bones alone, coupled with high and narrow pelvis, protruding facial brows, thick cheekbones and other characteristics, it is even more obvious; the entire pubic bone has osteoporosis Phenomena, the dorsal edge expands significantly backward, the ventral edge has a fracture defect, and the mandibular angle is about 120 degrees, indicating that the victim is about 50 years old; the victim's ribs have multiple fractures, and the fractures are in different healing stages , indicating that he had suffered multiple violent abuses, and a considerable part of the bloodstains collected from the villa near the fireplace belonged to the victim, which can also prove this; It was 10 times higher than the normal value, and the serum myoglobin concentration also showed signs of increase. Therefore, Team Leader Gu and I agreed that the victim should have been subjected to long-term abuse and corporal punishment, which induced rhabdomyolysis and then acute renal failure. dead."

"Victim No. 3 is also female; ossified nodules appear on the surface of the pubic symphysis, indicating that she is between 21 and 23 years old; the entire skeleton is 1.63 meters long, according to the customary height measurement method, on this basis plus The height of the soft tissue is 5 centimeters, which is about 1.68 meters. This is the height of the victim; the back spine has fractures, which should be caused by violent kicking. In short, the victim had also been violently abused; the cause of death is best judged, the inward fracture of the upper horn of the thyroid cartilage and the greater horn of the hyoid bone, indicating that he was strangled to death!"

After introducing the overall autopsy status of the three victims, Dai Jingxi let out a sigh of relief and nodded at Gu Feifei. Gu Feifei took the opportunity to conclude: "The DNA test results show that victims No. 1 and No. 2 are mother-child relationship, and victim No. 3 They have no kinship relationship with them. Judging from the composition of the residents in the villa and the information reflected in the bones, the first two should be Liu Xun and his mother. Later, we will confirm their identities through the coincidence of skull phases; The latter one is hard to say. Since I don’t have any background information about the little nanny, I can’t make an analysis and comparison. However, judging from her size and age, she is very inclined to be her. The specifics may only be determined after her appearance is restored. Yes, but it will take some time... By the way, there is a major discovery of bloodstains, among the bloodstains collected near the fireplace of the villa, there is no match with Jiang Qingshan, but there are bloodstains from Zhang Cuiying!"

"Ah, did Zhang Cuiying die in Liu Xun's villa?!" Han Yin and Zhang team were surprised almost at the same time, the air froze for a few seconds, Han Yin continued, "The villa may be the first scene where Zhang Cuiying was killed. And Captain Jiang is very interested in the villa, it seems that the two cases are really related!"

"Yeah, we'll be busy next time!" Gu Feifei smiled, staring at Han Yin and said.

"It's hard work for both of you, don't hold on all the time, take turns to rest for a while!" Han Yin smiled politely at Dai Jingxi, and turned his gaze to Gu Feifei's face for a while longer.

Gu Feifei knew that the key point in these words was her concern, and she felt very relieved.

After leaving the forensic department, it was almost morning. Team Zhang suggested to take a nap in his office for a while to refresh his mind. There was still a lot of work to do at dawn. Han Yin did not refuse and went to the office with him.Team Zhang really couldn't stand it any longer. Half a minute after his butt hit the chair, he started to grunt, while Han Yin just emptied his eyes, and his brain was still running at high speed:

The autopsy results were far beyond Han Yin's expectations. Liu Yao, Liu Xun's daughter, was not among the victims. Who would be the third deceased?Really a nanny?Or the equally mysterious "lover"?Of course, no matter which one of them died, Han Yin's previous inferences must be reconsidered.How to explain their previous low-key and secretive behavior style?Or they were indeed partners in crime, but after they succeeded, internal strife broke out, and one of them was killed?
Regarding the motive: the autopsy results showed that the three victims were all abused to a certain extent, and during that period, Liu Xun and his deposits were all cashed out, so it seems that the murderer's motive for committing the crime seems simple and clear, nothing more than seeking money Killing, through detention and abuse, forcing the victim to tell the bank deposit password, etc., thereby taking away huge sums of money!
About Zhang Cuiying: Her blood was collected in the villa, indicating that she was also tied to a column by the fireplace, and was detained and abused for a long time. Of course, what was said later has been reflected in the previous forensic report. But it is unbelievable that the place of detention is Liu Xun's villa!But if you think about it carefully, are there any similarities between the two cases?There are also detentions and abuses, and the victim also has financial changes. Maybe the perpetrators are the same group?If you look at it this way, it is not difficult to understand Zhang Cuiying's appearance in the villa.Of course, the biggest question is not here, but what role does her two daughters play in the case?Why would they lie about the circumstances of their mother's detention?What relationship do they have with the death of Liu Xun's mother and son?Could it be that they were the murderers who made these two murder cases?Is one of the two sisters Liu Xun's mysterious "lover"?What about the babysitter?Is it their internal response?After the crime was successful, the sisters teamed up to kill it?In this way, the two sisters are really a pair of rare "black widow killers", but is there really a black widow who will not even let her mother go?In short, no matter what, the two sisters are full of doubts.

Regarding Jiang Qingshan: If you don’t consider that he went to the property to inquire about Liu Xun’s villa, it is really difficult to connect his death with the case of Zhang Cuiying and Liu Xun, especially whether he was killed in the villa is still open to question.Including the unsolved case of thallium poisoning he was interested in, Feng Bing, director of the Department of Neurology at the University of Science and Technology and the No. Just eyeing the villa?
……

The more reasoning became more and more chaotic, and there were more and more question marks, Han Yin thought he should sleep for a while, just as he closed his eyes, he opened them again suddenly, he suddenly remembered that he had ignored the existence of a very important person—Where did Liu Yao go? up?still alive?What's the murderer's intention of keeping her alive?Judging from the photos, she is quite attractive, could she be treated as a sex slave?
Section [-] The Puppet Appears

With the assistance of the bank, the police obtained multiple withdrawal receipts from Liu Xun. The signatures on them were the same as those on the deposit receipt, which meant that the drawee was Liu Xun himself. Of course, this did not prove that he was willing.It's a pity that the time is too long, the surveillance video was overwritten, and the bank staff couldn't remember the situation at that time.

The survey work on the villa has basically ended, and there is no big harvest overall. Except for the blood stains found with the help of Han Yin, and two sets of car tire marks were extracted in the garage. The brand specifications are Michelin 255/50 R19 and Ma Guise 225/60 R17.The former is mostly used for large SUV models. Not surprisingly, it should be Liu Xun’s own car—a white Land Rover with the license plate Ming BX55966; the latter brand mostly cooperates with Shanghai GM and other automakers, and its specifications and patterns conform to those produced by Shanghai GM. The tires used by the Buick commercial vehicle, and the dark blue color of this car is the most popular, which also echoed the words of the little nanny who provided the car information to Han Yin.It is estimated that the Land Rover has been remodeled at present, and Buick commercial vehicles are very common in this city, so it is still very difficult to track down the suspect through the information of these two vehicles, but if there is a specific suspect , they can be used as a basis for confirming suspicion.

As for the focus of work in the next step, Han Yin suggested that some adjustments are necessary——Jiang Qingshan and the other two cases are actually somewhat inseparable. have any effect.It is better to concentrate manpower and energy on the case of Zhang Cuiying and Liu Xun, especially since Liu Yao's whereabouts and personal safety issues are involved, so it is even more necessary to solve the case as quickly as possible.Then the Wang sisters will definitely continue to be the focus of the investigation, and more importantly, the investigation will be carried out around the key figure in the case of Liu Xun's murder, the nanny. Although she may also be killed, she is more inclined to have internal strife with her accomplices due to.

Just now, the superimposition of the cranial phase and the restoration of the craniofacial have achieved results.

The former is relatively simple, just using software to overlay Liu Xun’s photo with the negative of the skull photo of the male corpse found under the floor of the villa. The superimposed photos can be determined to be the same person according to whether they can be consistent in anatomical relationship.The same goes for his mother's.The newly released identification results show that the bones No. 1 and No. 2 are indeed Liu Xun's mother and himself.

The craniofacial restoration technology is more complicated and takes a little longer. The principle is also known to Han Yin in previous cases. For this case, the skull of victim No. 3 is scanned by laser and a three-dimensional image is formed in the computer. According to forensic indicators, measure the width and height of the skull, the distance between the inside and outside of the eye socket, and the width and height of the pyriform hole, and then input these data and shapes into the computer. The computer divides the face into different regions in millimeters, and automatically matches the skull with skin. ; Then, in a database that integrates the facial features of 56 nationalities in China, select the appropriate facial features to add to it, and then print out the photos to complete the restoration.

Han Yin arranged for the investigators to bring the restored photos of the babysitter, and verify the identity of the babysitter from two directions—the missing report record and the registration information of various big housekeeping companies.Confirming the identity is only the first step, followed by a detailed investigation of the babysitter's background information, and then the most important thing is to find out about her social interactions, which must include her accomplices; The intersection of the sisters will be a decisive breakthrough for the detection of the entire case.

In the interrogation room, on both sides of the long horizontal table, Du Yingxiong and the Wang sisters sat facing each other.

After much deliberation, he finally decided to arrest the two sisters.I didn't move before, mainly because of the old problem - the criminal motive is difficult to judge.A few days ago, the police in Guangtian City reported that Qu Xiaojun had returned home. He was missing because he was involved in a car accident while working out of town.The local traffic police department and the hospital have already given proof of this, and according to him, he has not contacted Zhang Cuiying since he was fired from the hotel.Therefore, the previous analysis of "the motive for the murder caused by the property dispute caused by Qu Xiaojun" cannot be established, so the police hope to find the real motive of the sisters through secret observation and investigation; the other also wants to see if they have any accomplices, Or whether they were instigated—if they were involved in the crime.

But now the case has become more and more complicated. Liu Yao, one of the victims in the Liu Xun case, is still missing. Although theoretically, the case has been committed for more than a year, and there is little hope of Liu Yao's survival, but as long as the body is not found, the police can not give up. It races against time for search and rescue, so time does not allow it to continue dealing with the Wang sisters in a long-term passive posture.

"We found the first scene where your mother was killed. It is in Building 35, District C of Wanfu Mountain Villa. It is a two-story villa. The owner is Liu Xun." After a series of routine background information inquiries, Du Yingxiong began to lead the question to the case. At the core, he stared coldly at the reactions of the two sisters.

"What does this Liu Xun do? Why do you want to have trouble with my mother?!" The sisters straightened up in an instant, their eyes widened, and their faces were angry, but it was the elder sister Wang Yiwen who was rushing to speak.

"You really don't know Liu Xun? Have you never been to that villa?" Du Yingxiong continued to ask calmly.

"What do you mean?" Wang Yanwen asked in a surprised tone with her nose tight and her mouth slightly open.Immediately afterwards, her younger sister Wang Yanjing also frowned, squinted her eyes, and said unhappily, "We've never heard of this Liu Xun and the villa. Why do you ask that? Do you think we're lying?"

"I really want to believe you, but it's a pity that you haven't told the truth from the very beginning!" Du Yingxiong kept his composure and pressed on step by step, and said, "Combining the situation of your mother's bedroom and the scene of the villa and our forensic report, it can be proved that Before she died, she was detained in the villa for a long time and suffered cruel abuse, but you all said that the mother disappeared only one day before calling the police, can you explain it?"

"This, how is this possible?" Wang Yanjing raised her eyebrows in surprise, shrank her body, and leaned slightly towards her sister.The two sisters exchanged glances, and Wang Yanwen continued to argue: "Anyway, she is at home every night when we go home, maybe during the day when we are not going out to hang out with Qu Xiaojun. If Qu Xiaojun can like my mother at his age, That's about the same as perverts, who knows what tricks they do?"

"I forgot to tell you that we found Qu Xiaojun, and we can prove that he was not in this city when the crime happened!" Du Yingxiong said.

"Then it's possible that my mother has other lovers outside!" Wang Yanjing's tone was a little naughty, repeating her sister's pale excuse, "Anyway, my mother was at home at night during that time, who knows what she does during the day? "

Du Yingxiong curled his lips, smiled disdainfully, stared at the two sisters meaningfully for a while, and said, "Have you ever thought that claiming that your mother disappeared on May 5 is a big flaw?"

"We are telling the truth, and the employees in the store will testify to us. What you think is up to you!" The two sisters moved closer together, holding hands on the table, and exchanging Comforting, a gesture of common hatred.

Du Yingxiong smiled again, turned his head and glanced at the mirror behind him...

"These two sisters have been to the villa and have seen Liu Xun's body with their own eyes, and they know exactly what happened in the villa!" In the observation room next to the interrogation room, through the one-way glass, Han Yin and Team Zhang watched the interrogation.Han Yin knew that Du Yingxiong couldn't actually see them, but still nodded unconsciously, responding to Du Yingxiong's look back just now.

"Why do you say that?" Captain Zhang asked.

"During the questioning just now, the hero mentioned 'Villa' and 'Liu Xun' several times, and the sisters reacted with 'disgust' immediately. A subconscious reaction to an unpleasant experience." Han Yinchong raised his chin in the interrogation room and explained patiently, "The emotion of disgust comes from 'denial', to put it simply: for example, if you don't like seeing a certain person or a certain scene, you will subconsciously close your eyes If you don’t like to smell a certain smell, you will wrinkle your nose; if you don’t like to eat something, you will either press your lips tightly or grin back. And sometimes, when people feel extremely disgusted, these actions may Do it at the same time, for example, a certain person or a certain scene makes people feel extremely disgusted when they see or think of it, and they can't help but want to vomit... Do you think about the performance of the two sisters just now?"

"Oh, it's true." Team Zhang recalled a little, and praised, "An expert is an expert, and the angle of attention is completely different from ours!"

"Don't say that, we just need to focus on different directions in our work." Han Yin said modestly, and then analyzed, "In addition, when the hero first mentioned the villa and Liu Xun, the sisters had a momentary 'freeze reaction'. It belongs to the 'constrained freezing response', which shows that the question hits the point, and the sisters feel pressure and fear because of it; and the subsequent movements of shrinking their bodies and shaking hands are a kind of 'comfort response', corresponding to tension, Panic mental state. In short, in the event of the mother's murder, the Wang sisters showed anger, surprise, disgust, and fear, but no sadness, which is extremely abnormal."

"In this way, whether it is the intention of the two sisters or the instigation of others, they must have participated in the case!" Team Zhang answered clearly.

"Well, yes, let's do this here first. The hero has done a good job. Let's go and see if Xiaomei finds anything." Du Yingxiong explained, "Let me mention Liu Yao and see how they react..."

Technology department imaging room.

While the Wang sisters were being interrogated, Ai Xiaomei retrieved the computer hard drive from their office, together with the confiscated mobile phones of the two, Ai Xiaomei's task was to find out their accomplices or the intersection with the babysitter.

The mobile phones and landlines of the Wang sisters have been monitored, and no suspicious calls or text messages have been found so far; no other mobile phones and mobile phone cards have been found in their homes and offices, so how did they contact their accomplices during this period? Woolen cloth?Is it through QQ, Weibo or WeChat, or some other online instant messaging software?Ai Xiaomi really put in a lot of effort for this, and carefully "dissected" the computer hard disk and mobile phone storage. Unfortunately, the result was not satisfactory, and nothing was found.

"Are these two sisters really the only ones involved in the case?" Ai Xiaomei was very tired, but also very unwilling, half of her body was lying on the computer desk, her chin was propped up with one hand, her eyes were fixed on the computer screen, one With his hands on the mouse, he clicked blindly and inadvertently started the video playback software, and then the surveillance video of the Wang sisters began to be played on the screen.

As mentioned earlier, the Wang sisters mainly work in the main store on weekdays. For this reason, Du Yingxiong specially arranged manpower to monitor and record the area around the main store.After so many days, the on-site monitoring personnel and technical police officers in front did not mention any suspicious persons appearing, so Ai Xiaomei hadn't watched these videos seriously before, so she simply glanced at them in fast-forward mode.Of course, with her professionalism in this area, it will not affect her capture of suspicious images.

Suddenly, she seemed to see a familiar face. She quickly pressed the pause button, played back the picture with that face in slow motion, paused again, and zoomed in on the face.Although the man was wearing a long-brimmed sports hat, Ai Xiaomi still recognized the face.To be on the safe side, she deliberately called up a photo from the computer for comparison, and the result was the same, but the question is, how could it be her?
Ai Xiaomei archived the screenshots of the screen, then continued to play back, and saw that "she" got off a Honda car, the car number was Ming BL5958, and Ai Xiaomei called up the owner's information along the license plate number...

Follow the vines all the way, the rewards can be described as great, Ai Xiaomei is very excited, just about to take out her mobile phone to report to Han Yin, Han Yin and Team Zhang have already stepped into the technical department.They should have come an hour ago, but they met the bureau leader on the way, and then they were dragged to the office by the bureau leader to exchange the case, so they were delayed.

"Have you found anything?" Seeing Ai Xiaomei's high spirits, Han Yin sensed that there was good news.

"Yes! Who do you think I found?" Ai Xiaomei nodded triumphantly, and quickly slid the mouse to call up the previous screenshot.

"This, this is Liu Yao!" Captain Zhang was so shocked that his voice changed.

"It's indeed her, she's safe and well, and she's alive and well." Liu Yao's appearance in this way was really unexpected, and Han Yin was a little dazed for a while, and murmured, "What is she doing in the hotel? She's looking for the Wang sisters." ?”

"I think it should be. I deliberately expanded the scope and watched the surveillance video for many days, and found that Liu Yao has been to the restaurant more than once. What is suspicious is that the time points are very regular and unusually low-key. Short, basically every two days, at 7:32 p.m. by a Honda car, and leave every ten minutes, and that time happens to be when the hotel has the most guests, and the front door is relatively chaotic, which will not cause our monitoring personnel Attention, so I think Liu Yao may be the criminal partner we are looking for. It may be that she is worried that the communication equipment is not safe, and she feels that the most dangerous place is the safest place, so she adopts this direct face-to-face method to connect with the Wang sisters As for the Honda car, it was driven by a man whose face could not be seen clearly, and the car was registered under the name of a woman named Song Shuangshuang." Ai Xiaomi paused, tapped the computer keyboard a few times, and called up Song Shuangshuang's ID card After entering the information, pointing to her photo on the screen, she said, "This woman doesn't seem to be simple. I contacted the street police station in her jurisdiction, and the feedback information showed: Song Shuangshuang is [-] years old, and her husband Wu Delu left her building two years ago. He committed suicide by jumping up and down. Since old body injuries and bone fracture healing marks were found during the autopsy, and a large amount of life insurance was involved, the criminal police of the sub-bureau once suspected the possibility of murder and fraudulent insurance, so they began to investigate. According to Song Shuangshuang himself Introduced to the branch police: Her husband used to run a medium-sized real estate company. Later, due to investment failures, the capital chain was broken and a large amount of debt occurred, which eventually led to the bankruptcy of the company. Of course, the debt collectors will not let him go. It is said that every three days In Chawu, someone came to collect debts, and was sued by many creditors in court. It can be described as internal and external difficulties, and he was devastated. Soon after, under the huge debt pressure and mental distress, Wu Delu suffered from severe depression. Strong self-mutilation and Suicidal tendency. For this reason, she took him to the mental hospital many times, and she also took special precautions against Wu Delu's dangerous behaviors such as approaching the balcony or using knives, etc., but she still failed to prevent it. Then, based on Song Shuangshuang's confession, the criminal police of the sub-bureau conducted an investigation. In order to investigate and collect evidence, the psychological hospital provided the husband and wife's multiple visit records, and the relevant attending psychologist also issued detailed written diagnosis and treatment records, which fully proved the credibility of the confession. As a result, the branch office canceled the investigation of the case, and Wu Delu was classified as a suicide. .Because the large amount of life insurance had been insured before his death for more than two years, and the insured person jumped to his death due to illness and could not control himself, which is not an act of actively depriving his own life, so the insurance company can only admit the compensation. Song Shuangshuang Soon after receiving the compensation, she sold the property and moved out of her original residence, and her current whereabouts are unknown. However, she has a six-year-old son who still lives with her grandmother in another property in the jurisdiction.”

"Do you feel that the story seems familiar?" After listening to Xiaomei's report patiently, Team Zhang said, "If you look at the suicide case alone, it is reasonable, but we have to compare it with the case in hand. , it’s a bit intriguing!”

"Well, there are also plots of abuse and detention, large sums of money involved, and family members living or dying!" Han Yin nodded in agreement, "The husband is dead, but the wife Song Shuangshuang is alive; the father and grandma are dead. Liu Yao, whose daughter is also a granddaughter, is alive; her mother is dead, and daughters Wang Qiwen and Wang Qijing are alive. And the strangest thing is that the living people still have intersections with each other!"

"Comparing this way, the initial judgment of the criminal police of the sub-bureau should be closer to reality. It's just that the criminal is too cunning and made good use of the victim's own shortcomings. However, this is also due to the cooperation of Song Shuangshuang, or Song Shuangshuang is simply The murderer?" Ai Xiaomi, who was between the two, grinned with contempt on her face, "How did Song Shuangshuang get involved with Liu Yao, and how did Liu Yao become an accomplice of the Wang sisters? Anyway, it's a bit messy. What shall we do next?"

"Let's issue an investigation report first, and let the sub-bureaus and police stations in the jurisdiction help find Liu Yao and Song Shuangshuang?" Team Zhang looked at Han Yin with a consulting look, "I will send someone to Song Shuangshuang's mother-in-law's house to find out if there is any Her news; arrange a few more people around, in case Song Shuangshuang comes back to visit the child."

"Be sure to keep a low profile. If you find Song Shuangshuang or Liu Yao's traces, just pay attention to follow them. Don't rush to close the net." Han Yin nodded slightly, and said calmly, "I always feel that there is an invisible ghost behind these people." Big hands are in control."

"Is the direction too single? What if we can't find them?" Team Zhang took a deep breath and asked with a frown.

"I was going to say this, let the hero release the two sisters, and send more people to monitor the area near the hotel. Maybe Liu Yao will go to the meeting." In fact, no one else needs to mention it. Finally, he took out his mobile phone and dialed Du Yingxiong, and asked in a low voice, "Is it over? When Liu Yao was mentioned, how did they react?"

Du Yingxiong responded on the other end of the phone: "It feels like they are quite scared!"

Chapter [-] The Devil's Lair
The identity of the little nanny was finally confirmed!

The investigators went to dozens of domestic service companies, large and small, in the city. Finally, someone identified the photo of the babysitter. The copy of the ID card kept by the domestic service company shows that her name is Gao Ying, she is 23 years old, and she is from outside the city. .According to the person in charge of the housekeeping company: Gao Ying applied for the company on her own initiative. She is honest, quick at work, and has been trained.Liu Xun originally thought she was not very good-looking, so he didn't like her very much, but he heard that she was taking care of the elderly who were bedridden and unable to take care of themselves. Reluctantly hired her.As for the so-called unattractive appearance, it was because there were two conspicuous red spots on his face.

Based on the information above, Gao Ying's entry into Liu Xun's home to work was not premeditated, and people in the housekeeping company who had contact with her all said that she was a serious child and had never seen her make any shady friends. .Based on this analysis, Gao Ying may be just a victim and has nothing to do with the whole crime, but what makes the investigators unable to let go is the mystery she usually displays!

"Should we send people to Gao Ying's hometown for further investigation, or should we temporarily abandon this line and focus on tracking down Liu Yao and Song Shuangshuang?" At the moment when the police force is seriously insufficient, Team Zhang is somewhat hesitant.Han Yin thinks it's okay to give up. Although it is impossible to determine what role the Wang sisters, Liu Yao and even Song Shuangshuang played in the entire series of cases, it is certain that they are all involved in this case, and there is no need to go through Gao Ying. The clues connected them with the case; conversely, if those people can be dealt with, it will be clear whether Gao Ying is involved in the case.

However, what they didn't expect was that they didn't need to wait so long. Gu Feifei had already passed the in-depth inspection of the bones and revealed the mysterious side of the babysitter Gao Ying.

Earlier, Dai Jingxi performed the autopsy on the babysitter. At that time, she found that the babysitter's joints showed signs of strain and the bones showed slight degeneration.Since the autopsy of Liu Xun's mother and son came first, she instinctively believed that the cause of the symptoms was the same malnutrition caused by long-term detention as Liu Xun's mother and son. In addition, Gao Ying's cause of death was relatively clear, so she did not go any further. observation.Later, Gu Feifei also found the variation of bones and joints during the re-examination, but she thought that at the young nanny's age, the degeneration should not occur so quickly, so she extracted bone samples and observed them under a microscope, and found that the naked eye Undetectable cracks, this is a manifestation of connective tissue disorder, indicating that the little nanny suffered from autoimmune connective tissue disease before his death. Further lupus tests were performed, and the result was positive, which means that the little nanny suffered from systemic lupus erythematosus before his death!
With this conclusion, the series of weird behaviors of the babysitter Gao Ying can be explained: if the disease of systemic lupus erythematosus is mild, or the disease has stabilized after treatment, you can participate in daily work; of course, Gao Ying should be She concealed her condition from the housekeeping company and Liu Xun, and she tried to avoid being overworked and exposed to strong light from the outside.This can explain why Gao Ying seldom shows up outside, she always wears a hat when she goes out, and she tries to buy groceries at a time when the sun is not strong; and she is unwilling to communicate with other babysitters, which may be due to her illness. The inferiority complex of the disease, and indeed because of the disease, red spots appeared on her face, which made people look uncomfortable.

The doubts about the little nanny were completely resolved, but the other women were still mysterious.

Song Shuangshuang's mother-in-law cried to the investigators that Song Shuangshuang disappeared after throwing the child to the old man, and did not pay child support.The old man doesn't care about money, he is his grandson anyway, but the child often yells and misses his mother, which makes the old man very helpless.

Song Shuangshuang's car was not driven by himself, and it is hard to judge whether he is alive or dead.Han Yin asked Xiaomei to check whether the car has violation records and the surveillance video of the relevant roads. If the vehicle is found in the surveillance, he will try to piece together the frequented routes of the vehicle so that he can notify the traffic police department to assist in the search.

In the previous interrogation of the Wang sisters, when Du Yingxiong mentioned Liu Yao, although the two sisters shook their heads and denied hearing the name, their eyes showed deep fear, which inevitably made Du Yingxiong feel that they seemed to have something. The fatal handle fell into Liu Yao's hands, and if Liu Yao really controlled the two sisters because of this, what would be her ultimate goal?Don't think too much about it - it's definitely money!This made Du Yingxiong think that the reason why Liu Yao showed up at the restaurant so regularly was not the so-called exchanging news and discussing strategies to evade the police, but to take away part of the hotel's operating income.From this point of view, Liu Yao or whoever behind her didn't particularly care about the investigation of the Wang sisters by the police. Will not be betrayed by the Wang sisters.Of course, they didn't expect that the police would be under surveillance secretly, and they had already noticed Liu Yao's presence, so the possibility of Liu Yao appearing again should be quite high!According to the rule of time, tonight is the money collection day, and the investigators headed by Du Yingxiong are all waiting and watching!

At 7 o'clock in the evening, the Honda car arrived as scheduled.Like the previous few times, the young man stayed behind in the car. Liu Yao got out of the car wearing a long-brimmed sports cap and a pink leather bag on her arm, and slipped into the restaurant under the cover of night and diners.Not long after, her figure appeared at the door of the hotel again, the leather bag on her arm was already bulging.She walked a few steps, came to the Honda car, opened the door, and got in the car.

Honda, start, drive away.In an instant, many cars that looked like private cars started up in the parking lot of the hotel and even in the nearby streets. At the same time, the road monitoring screen of the traffic police command center was remotely connected to the large screen in the imaging room of the technical department of the criminal police detachment. An all-round tracking and pursuit The action is unfolding!

At this time, around [-]:[-] p.m., the rush hour for vehicles has passed, but there are still many vehicles on the road, which makes it difficult to track, especially because I don’t know if it is because of habit, but I am still alert, and the Honda is driving very fast.Fortunately, the previous layout was detailed enough, and with the overall control of the command center located in the detachment's imaging room, the target was always within the tracking line of sight...

More than 40 minutes later, near 8:[-] p.m., the Honda drove out of the urban area, and turned into a rural road not long after.There are farm houses on both sides of the township road, most of which are tile-roofed houses with ridges, and two or three-story single-story buildings are rare.The Honda car stopped slowly in front of a three-story single-story building, but it did not turn off. Immediately, the large iron gate in front of the courtyard was pulled open, and the Honda car drove into the courtyard. There are also two cars parked here, one is a Land Rover and the other is a Buick commercial vehicle.

This place is Shatian Town, Longtou Village.

After confirming the specific location of the target, Du Yingxiong led a team of investigators to investigate overnight. Through the coordination of the local police station, they quickly met the village director of Longtou Village.

The village director looks more than 50 years old, and he seems to have a lot of experience. He must know a thing or two about all the big and small things in the village.Hearing that Du Yingxiong mentioned the small building that the Honda drove into, he immediately opened up the conversation and said, "The one you mentioned is Tian Weimin's house. It is the first private building in the village. It has been built for about 30 years."

"The building can be built so early, Tian Weimin's family has a solid foundation!" Du Yingxiong said.

"Hey, what kind of family background, his parents left early, it's all done by this kid himself." The village director sighed and said with emotion, "Tian Weimin was the first construction team in the village, and he was still called a contractor at that time. The boss, hired a lot of people under his command, and gradually grew up, taking on many projects in the city. He not only built small buildings in the village, but also owned several properties in the city. But at that time, Tian Weimin mainly lived in In this building in the village, his girl and son-in-law didn’t move to the city until she died of illness.”

"Then who lives in the building now?" Du Yingxiong continued to ask.

"Tian Weimin's girl and son-in-law!" The village director rolled his eyes and said after a little calculation, "Tian Weimin is an only daughter named Tian Meiyun; his son-in-law is a door-to-door son-in-law named Sun Jian. Their son lives in the building now. Sun Duo, Sun Duo's partner, and a woman who is said to be Tian Meiyun's god-sister!"

"Are you talking about these two people later?" In response to the village director's words, Du Yingxiong took out photos of Liu Yao and Song Shuangshuang and asked the village director to identify them.

"That's right, that's right, just these two women, the younger one is Sun Duo's object, and the older one is his god-sister." The village director pointed to the photos and said.

"Then why did their family come back to live?" Du Yingxiong put away the photo and asked.

"The construction company is ruined!" The village director sneered, and after thinking about it, he said, "It seems that I moved back three or four years ago. It is said that the company is ruined, and I owe a lot of debts. If others owe her, I will not come back. The houses and cars in the city were all paid off, so I had no place to live, so I had to move back to the village. When I first came back, Meiyun was behind me all day long, begging the village for some small infrastructure projects to make ends meet. She was very destitute. The past two years have slowed down, and I don’t know what business to do. Anyway, it’s a bit of a comeback. Look at the yard of her house. There are several cars parked, and the small building has been redecorated inside and out. The whole family They always wear gold and silver when they go out, and they are arrogant, plus no one dares to mess with her kid, the family is considered to be the most beautiful in the village!"

"What does her son do?" Du Yingxiong looked puzzled.

"That kid doesn't have a serious job. He leads a group of local ruffians around all day long. Fights in the village must be indispensable to them. We have dealt with this many times, but he didn't cause any special harm to anyone. You can’t do anything to him!” The chief of the police station beside him frowned, interjecting with a headache.

"Yeah, I'm rich, my son is good at messing around, Tian Meiyun's dress is so sly, she looks like the underworld big sister on TV!" The village head chimed in, and then deliberately wanted to highlight his personality status in the village, and continued, "But that kid in her family is nice to me, and their family is very polite when they see me. Some time ago, some people from the city came to inquire about their family. I guess they were former creditors. I reminded him when we met, I didn't expect that kid to be quite polite, he insisted on treating me to dinner after a few days, he thanked me for a good meal, and specially asked me not to say anything to the outside world."

"Oh?" Du Yingxiong couldn't help being surprised, and quickly asked, "Is the person in the city an old man in his 60s?"

"Yes, it should be about that age." The village director paused, rubbing his forehead to remember, and said slowly, "I remember that he introduced himself as...Jiang, yes, it's Jiang! Do you know him? Isn't it a debt?"

Du Yingxiong nodded, shook his head again, did not respond clearly, but was secretly excited: This is the right match.It seems that Captain Jiang was also killed by this family!
"By the way, is Sun Duo left-handed?" At the end, Du Yingxiong suddenly remembered this detail and asked.

"Yes, I have an impression of this. I also praised him that people who are generally left-handed have very smart heads." The village director replied without thinking.

With the cooperation of the village director and the local police station, the background information of Tian Meiyun's family was basically found out.Du Yingxiong left a few groups of people to closely monitor the movements of Tian Meiyun's family, and he drove back to the detachment to report quickly.In the night outside the car window, the stars are particularly bright, which may indicate that the dawn of tomorrow will be particularly shining!

After listening to Du Yingxiong's report, the support team and the detachment met urgently to discuss the countermeasures.

"A suspicious suicide case, and three murder cases. These four seemingly unrelated cases finally found an intersection in Tian Meiyun's family. The three members of this family may be the real murderers. The motive must be to seek money. .So how do they choose their targets and what methods do they use to approach their victims?"

"Could Liu Xun's lover be Tian Meiyun?"

"Even if this family did it, there must be someone who counts. Who will be the mastermind?"

"The most puzzling thing for us is that, except for the case of Captain Jiang's murder, in the other three cases, there were immediate family members who finally obeyed the murderer and participated in the crime to varying degrees. How did Tian Meiyun's family do it?"

"Did Team Jiang end up being killed because he secretly followed this family?"

……

At the beginning of the discussion, a series of questions came oncoming.In fact, the local colleagues knew very well that although Gu Feifei was in charge of the support team, the core of handling the case was actually Han Yin, so their suspicious eyes naturally turned to Han Yin.Gu Feifei was no stranger to such a scene, so she turned slightly sideways and looked at him beside her.But Han Yin didn't seem to be eager to give an answer. He raised his hand to take off his glasses and rubbed his eyes vigorously with the back of his hand, looking very tired.After a while, he put on his glasses and said in a rare and slack manner: "I won't say more, it's useless to say it. In fact, you should be very clear that no matter what answer I give you, there is no evidence to prove it." and I believe that in the days to come, it may be difficult to find conclusive evidence for conviction."

"Ah! Then what should we do? What do you mean by this attitude?" This was probably the first time Team Zhang expressed doubts about the support team, especially Han Yin.

"If there is no evidence, don't handle the case?" A police officer handling the case said sullenly.

"If the case is easy to handle, why would you guys do it? I thought you were quite professional, so why are you talking so irresponsibly?" Another police officer who handled the case said almost scoldingly.

"Everyone, don't worry, Teacher Han Yin didn't mean that." Gu Feifei couldn't see it, so she had to jump out and explain.She really didn't expect that Han Yin's mouth would have such a keynote, which made the atmosphere of the whole meeting very uncoordinated, but she knew in her heart that this was not Han Yin's usual style of handling cases, and there must be his considerations in it, so she continued She gave him a hard look, and motioned him to stop stretching, and if you have any suggestions, speak up quickly.She smoothed things over by herself first: "That's it. The motive for committing the crime has been thoroughly analyzed, and it can basically be determined that it is seeking money. From the perspective of the law of committing the crime, the interval between committing the crime is quite long, especially now that they have controlled the Wang sisters. It’s hard to say whether you will continue to look for the target if you have a long-term meal ticket. Therefore, it is indeed difficult to obtain evidence in this situation, but I believe Teacher Han will find a solution.”

"For such a big case, there must be a clear plan, right?" Captain Zhang calmed down, and seemed to see that Han Yin actually had something in mind, so he said earnestly, "What do you want to do, no matter manpower or material resources, we will help you." I will do my best to satisfy you!"

Han Yin's face finally showed his previous self-confidence. Of course, he had already made up his mind. The reason why he pretended to be negative was to let Team Zhang and the others be fully prepared to face difficulties and fight a tough battle. The criminal pattern of the case is unprecedented, and when the truth is revealed, it will definitely surprise everyone.Han Yin smiled slightly, and said calmly: "Don't bother, let's do something simple and rough, capture all of them and interrogate them one by one, I don't believe that none of them was exposed!

Section [-] Prisoner's Dilemma
The prisoner's dilemma is a game theory model proposed by an American company in the 20s.A brief overview: a special game between captured prisoners reflects that the best choice for individual interests is not the best choice for the group.

In fact, the application of this set of theories to criminal investigation and interrogation is not new. It is left over from our ancestors' play, which is similar to the psychological basis of "estrangement".It mainly uses the psychological characteristics of criminal suspects to seek advantages and avoid disadvantages, and on the basis of asymmetric interrogation information, to break down the members of criminal gangs individually.It is mostly used in situations where the criminal suspect has been locked, but there is still no or lack of effective clues and evidence. Through the mutual exposure of the suspects, the criminal gang will eventually be wiped out.

This is the case in the current case. The suspects are basically targeting Tian Meiyun and his group, but let alone the evidence, the criminal pattern is still a mystery—except of course Han Yin.This requires a choice, whether to continue to closely monitor and wait for them to voluntarily make mistakes, or to induce them to confess through certain interrogation techniques?Of course choose the latter.The former, as Gu Feifei said, can't afford to waste time, and Han Yin is very confident that these prisoners will make choices that benefit the police when faced with a common predicament.

When Han Yin announced that he would use the game theory as an interrogation strategy, he specifically pointed out a fact that surprised and shocked everyone—in this series of cases, except Team Jiang, the other of victims may have died at the hands of those closest to them!

Now, the seven suspects are all in place, including: Tian Meiyun and her husband Sun Jian, son Sun Duo, prospective daughter-in-law is Liu Xun's daughter Liu Yao, god-sister is Wu Delu's wife Song Shuangshuang, and Zhang Cui Ying's two daughters, Wang Qiwen and Wang Qijing.According to Han Yin's instructions, the suspects were interrogated separately and at the same time, so that information can be connected at any time and the interrogation strategy can be improved.For this reason, on the basis of the original three interrogation rooms, the detachment deliberately vacated four offices and temporarily transformed them into interrogation rooms.

In terms of interrogators: the support team is led by Du Yingxiong, and the detachment sent a deputy detachment and a team leader in charge of serious case investigations; the other four are veteran pre-qualification examiners, who were in charge of major cases before the "integration of investigation and trial" The trial of important cases can be described as quite mature and sophisticated.

The surveillance images of all the interrogation rooms were finally connected to the large screen in the imaging room of the technical department. Many important leaders of the Municipal Bureau came to the scene to pay attention to this unique special interrogation with the case handling personnel.The unusually serious atmosphere filled the originally small space with a feeling of suffocation.

I don’t know if it’s also a little boring. As the person in charge of the interrogation, Han Yin should have been at the closest place to the big screen, but he chose to stand far away by the door, with his arms folded and his body slightly leaning against the wall. , staring at the big screen with a little slack in his eyes, and an inexplicable melancholy in his brows. Compared with the tense and excited emotions of everyone around him, he seemed to be distracted.

Han Yin's mind is indeed not fully focused on the trial in front of him, because he can predict that the final result of this tug-of-war may only be staged.Don't forget that this is a gang crime, and among the members there must be some in the leading position and some in the subordinate position. Due to the particularity of the crime pattern, the criminals in the subordinate position may eventually be "willingly" to bear most of the crimes. However, the mastermind behind the scenes and the real beneficiary can escape the heavy punishment of the law.

So, what exactly is the so-called special and rare criminal pattern that Han Yin has repeatedly emphasized?
In fact, Han Yin was puzzled before, until he saw the picture of Liu Yao appearing in the Wang sisters restaurant, he suddenly realized that the criminal pattern of the case was no stranger to him, even before he took on this task. Give examples to students in class.Yes, like the "Heyang Slave Case", this is also a typical case of controlling the situation through a hostage complex.To put it more bluntly, the three members of Tian Meiyun's family used specific methods and brainwashing to shape the original victims into victims, and finally firmly controlled Song Shuangshuang, Liu Yao and Wang's sisters, and became their criminals. Accomplice and money-making tool!In this way, the "master-slave relationship" is relatively clear, so how to solve the problem of Tian Meiyun's family's confession?Of course, the general direction was introduced earlier. Through the interrogation strategy of the prisoner’s dilemma, let them play games with each other. It's up to the police to find out their weaknesses and discover information that could be game capital.

Leaving aside other people, the son Sun Duo should be able to overcome this family of three alone.The village director can prove that he knows Jiang Qingshan, and that he is left-handed, which fits the scope of the murderer who killed Jiang Qingshan pointed out in the previous forensic report. Not surprisingly, Jiang Qingshan was killed by him.If guided properly, he will definitely join the game's camp.

It is more difficult for Tian Meiyun and his wife.Judging from the development of the case, they did a perfect job from planning to planning to execution.They should be able to think of the current situation, or they have designed countermeasures earlier, and they may be charged with illegal detention and cover-up at the end of the trial. There is very little room for them to gamble, so they betrayed each other. The probability is not high.

If according to the above, Tian Meiyun and his wife were only imprisoned for misdemeanors in the end and did not receive due legal punishment, it would be a failure for all investigators. Han Yin would never allow this situation to happen, so he Think of the original profile.

In that profile, Han Yin repeatedly emphasized the connection between Jiang Qingshan and the murderer. At that time, he believed that the most likely reason was that the murderer had been arrested by Jiang Qingshan.Then it was discovered that Jiang Qingshan conducted a series of visits and investigations on thallium, which made Han Yin think that he might have taken over a thallium poisoning case in the early years, but because Feng Bing concealed the real situation, the final investigation result of the case There was a reversal, and then because of an old news about the unsolved case of thallium poisoning, Jiang Qingshan had an insight into the mystery... So at that time Han Yin instructed Team Zhang and Gu Feifei to look through the files of old cases handled by Jiang Qingshan and Feng Bing's retirement. previously treated cases.However, due to the large number of files and the vague target, it was stopped halfway. But now that there is a specific suspect—Tian Meiyun's family, it is much easier to go back and find the files!So while this interrogation was going on, Gu Feifei and Team Zhang were respectively leading their staff to search for cases related to Tian Meiyun's family in the archives, and Ai Xiaomei was sent by Han Yin to the University of Science and Technology to find the case related to Tian Meiyun's family there. intersection.

Just when Han Yin was somewhat in a trance, the interrogation here officially started. In the seven small screens displayed on the big screen, the suspect was no longer alone in the interrogation room, and interrogators had entered one after another. , Han Yin also calmed down and stared at the big screen intently.

In fact, anyone can understand the theory of the so-called prisoner's dilemma, and the grasp and application of details are the key to determining the level of the entire interrogation and its success or failure.Conventional interrogation techniques are nothing more than creating a space atmosphere to make the suspect feel oppressed and cramped; or using imitation sound, smell, left-handed writing, and crowd watching to deepen the suspect's anxiety and exhaustion, etc. .However, Han and Yin hope that the interrogators will not only do enough homework, but also maintain a psychological aggressiveness towards the suspect.

Now it can be seen that in the picture, all the interrogators are struggling to hold a thick stack of files in their arms.They sat opposite the suspect, and at the same time put the dossier on the long table in front of them. They also added an action of shooting the dossier, so that the suspect could intuitively notice the existence of the dossier.The interrogators then called out the suspect's name with great precision, as if calling an old friend.The design of these links is to convey a message to the suspect - he has been concerned and investigated by the police for a long time!
The interrogators began to ask questions, the wording was not only rigorous as usual, but also very direct and deterrent.For example: Facing Song Shuangshuang, the interrogators did not mention suicide by jumping from a building at all, and directly pointed out that Wu Delu was pushed down from upstairs and fell to his death; for Liu Yao, the interrogators asked her if she had not had a good relationship with her grandmother Okay, so freeze her to death without hesitation; shortly after the interrogation of Sun Duo began, the interrogator threw a forensic report in front of Sun Duo, emphasizing that the forensic report proved that Jiang Qingshan was beaten to death by a left-handed stick In short, the subtext of these words is: "We know how those people died, and we know who did it!"

Also, the interrogators in the screen always show a majestic look, so that the suspects can feel that they are people who can make decisions and are trustworthy characters, so that it is possible to accept "incentives"!Of course, due to different national conditions and laws, we will have certain limitations in our commitments regarding interests.Foreign countries can reduce the level of crime and the length of sentence through "confession deals", but our country does not allow any "bargaining" with criminals in principle, and can only adopt more vague statements, such as the line that often appears in public security-themed film and television dramas ——Leniency for confession, strictness for resistance!Han Yin asked the interrogators to repeatedly emphasize that if the other party actively confesses the crime, there will be considerations for sentencing. This concept should be deeply implanted in the other party's heart, and the attitude should make the other party feel that you really think about him!

……

Since early in the morning, the interrogation has lasted for four or five hours, and the progress has not been smooth. I don’t know if Tian Meiyun and his wife have raised their points in advance. The suspects generally feel that the evidence currently available to them is not enough They formed a threat, so they formed a tacit understanding. No matter what questions the interrogators asked, the other party almost responded with silence.

This is not beyond Han Yin's expectation. As pointed out earlier, this will be a tug-of-war, because although this case is committed by a gang, the special thing is that each member is responsible for the murder himself-either choose to confess the crime voluntarily, And if you actively cooperate with the police to expose others, you may not be sentenced to a severe sentence; or if you deny the crime together, everyone may escape legal sanctions; or if you are exposed by others, you will be sentenced to a felony or even the death penalty.As the so-called first-tier heaven and first-tier hell, it is a choice about life and death. It is understandable to try to resist and fight desperately. At least they have to give them a process of psychological entanglement before they can make a rational choice.This is exactly the game process pointed out in the Prisoner's Dilemma, and the essence is that it is difficult for people to fully trust each other when the information is unknown, and they will eventually rationally tend to choose the choice that maximizes their personal interests.

Of course, excellent interrogators are good at grasping the initiative. Seeing that the time is almost up, the interrogators turn to adopt a gentle approach at the right time, and use a posture of empathy to show that the police understand that the person being interrogated is actually a victim. Most of their behaviors, They all happened in a situation where they could not help themselves and were coerced by others... This is equivalent to adding firewood to the minds of the suspects who are sprouting little sparks, thus pushing them to make rational choices earlier.

The first to break down the psychological defense and the quickest to make a rational choice was the younger sister of the Wang family, Wang Jingjing.This is actually in line with the norm, because Wang Yujing is the one with a strong sense of dependence in the sister relationship, and she is docile and has no assertiveness. She is very easy to accept psychological hints. Among the sisters, she should give in and accept Tian Meiyun and his wife earlier. The one in control is, of course, easily swayed by the police's mind-boggling tactics.But the core factor is that the two sisters were included in the gang for the shortest time, just like the reporter who finally escaped in the "Heyang slave case" was also the victim who was imprisoned by the criminal for the shortest time.

"My sister and I beat my mother to death," Wang Qijing said.

"Why?" the interrogator asked.

"Hate!" Wang Qianjing said.

"Hate what?" the interrogator asked.

"I don't know. Anyway, I just feel very angry. I just want to hit her. The harder the beating, the more comfortable I feel. In fact, we don't know what the result is. My mother died in a daze!" Wang Qijing said.

"Did you release the fear in your heart?" the interrogator asked.

"Yes, that's right!" Wang Qianjing said.

"Did someone force you?" the interrogator asked.

"I didn't say it directly." Wang Qianjing said.

"Then how did you feel it?" the interrogator asked.

"Liu Yao took me and my sister to see the corpse under the floor, and said that we can choose for ourselves, whether to lie in it or to live well. By the way, I want to expose it. Liu Yao said that she killed her father, her Grandma and her nanny." Wang Qijing said.

"What did the others do?" the interrogator asked.

"Tian Meiyun and her lover don't talk to us very much, but they are quite leisurely. They just drink tea and watch TV. It's mainly her son, god-sister, and Liu Yao who take care of us," Wang Yijing said.

"How did you know Tian Meiyun's family?" the interrogator asked.

"Tian Meiyun and her lover often go to the restaurant to eat. They are regular customers, but we don't have much contact with each other. Suddenly one day Tian Meiyun approached my sister and said that she wanted to cooperate with us to open a branch, mainly using our signboard. As for her own investment, and then Give us a franchise fee, or jointly invest in a certain proportion, and then share it in proportion. She said that she would make an appointment for a time to discuss in detail. A few days later, she invited the three of us, mother and daughter, to the villa in Wanfu Mountain Villa. Then lock us up."

……

Not long after Wang Yanjing made a confession, Wang Yanwen also spoke, and the confession was similar to that of her sister.

Then came Liu Yao, who admitted that she was involved in the deaths of her father, grandma and nanny.

"How did your family know Tian Meiyun and his wife?" the interrogator asked.

"My mother-in-law (Tian Meiyun) and my dad were classmates in junior high school. They met again at a class reunion. Then she began to contact my dad frequently, and gradually became my dad's girlfriend. She often stayed at my house. But who Knowing that she is a married woman, my father-in-law (Sun Jian) ​​came to find her and had a big fight at home. My father wanted to use money to settle the matter, but the father-in-law asked for 500 million. My father couldn’t get it out, so the father-in-law just relied on it. I’m not leaving. Later, my boyfriend (Sun Duo) and Aunt Song (Song Shuangshuang) somehow moved into the house…” Liu Yao said.

"What did Tian Meiyun and his wife do to your family?" the interrogator asked.

"I didn't do anything. Usually we have a lot of contact with my boyfriend and Aunt Song. They don't let us wear clothes. We have to ask their permission to eat, sleep, and go to the bathroom. If we don't obey the discipline, we will be tied to the pillars in the living room." Fortunately, Xiaoduo is a kind person and took good care of me... I want to report, but Aunt Song told me that she pushed her husband downstairs, and Zhang Cuiying was beaten to death by her two daughters." Liu Yao explain.

"Did you play tricks on your father and grandma?" the interrogator asked.

"I love Xiaoduo, but they object, so I can't help but..." Liu Yao said.

The fourth person who confessed was Song Shuangshuang. Unsurprisingly, she told the interrogators that her husband Wu Delu was pushed downstairs by her.

"Do you regret it?" the interrogator asked.

"There is nothing to regret. I hate him. I put aside a good real estate business and went to speculate. As a result, my son and I suffered with him, and we still took care of our lover outside. Fortunately, my sister woke me up, otherwise I would Still in the dark. My sister is right, this kind of man is not a pity to die!" Song Shuangshuang said.

"The sister you mentioned is Tian Meiyun, right? Was she involved in pushing your husband down the stairs?" the interrogator asked.

"No, she just said that she would take me in as her younger sister, saying that I don't need to be such a wimp like my husband, and she is willing to take care of my life for the rest of my life." Song Shuangshuang said.

"Have you handed over all your husband's insurance compensation to Tian Meiyun and his wife?" the interrogator asked.

"Of course, Wu Delu's company owes their family project money, and it's only natural to pay back the debt!"

"Even if they want to pay, the family shouldn't imprison the two of you, right? Why didn't they call the police? Is there no chance?" the interrogator asked.

"At first, my nephew Xiao Duo said that if we dared to call the police, he would kill my son. Xiao Duo was so cruel that he could do anything. He killed the old man surnamed Jiang!" Song Shuangshuang said.

Sun Duo's bone is relatively difficult to crack, and he seems to want to fight to the end, but after listening to the recordings of the confessions of the previous people, he understands that the general situation is over, so he can only try his best to protect himself.

"I did it. I heard from the village director that a man surnamed Jiang was inquiring about our family, so I told my mother. I don't know how my mother knew the old man. She said he was a policeman and might be targeting us. I did. I quietly followed him, and gave him a stick when I saw no one was there. I didn’t intend to kill him, but who knew that the attack would be serious.” Sun Duo said.

"Who threw the corpses of Zhang Cuiying and that old man?" the interrogator asked.

"It's me. I wanted to put the old man and Zhang Cuiying under the floor of the villa, but my mother was worried that the old man had accomplices and thought the villa might be unsafe, so she asked me to throw their bodies outside. I thought about it for a while." I took a look at the limelight for a while, and went back and threw away the corpses under the floor... I did this, and I listened to my mother and my father. Everything was planned by them. I will do what they say, they They are the masterminds, and I want to expose them, so this counts as meritorious service?" Sun Duo said.

"Is there anyone else who can testify?" the interrogator asked.

"No, they only explained their plans to me when there were only three of us," Sun Duo said.

……

So far, the results of the interrogation have basically met expectations, and as analyzed by Han Yin, Tian Meiyun and Sun Jian are the real behind-the-scenes culprits, while others have not formed key accusations against them.The evidence for Sun Duo's accusation alone is a bit weak, and it is easy to be overturned by the two together. This is probably what the couple planned from the beginning. If something happens, Sun Duo will be the scapegoat.Even his own son can calculate, this kind of cruelty is really outrageous.It can also be imagined that if they don't come up with something practical, the strong anti-social psychology of these two people will never be captured by the interrogators.

Fortunately, the previous arrangement of Han and India once again played a decisive role.

Jiang Qingshan was killed by Tian Meiyun and his gang during the investigation of the thallium element. Before Gu Feifei looked for the medical records related to the case, he could first clarify two questions:
[-]. It was a suspected case of thallium poisoning.Since Feng Bing's hospital has no relevant diagnosis and treatment records, there is a high possibility of misdiagnosis.Clinically, thallium poisoning often starts with neurological symptoms, which are easily misdiagnosed as neurological diseases, such as Guillain-Barré syndrome, multiple neuritis, hysteria, porphyria, etc. The diagnosis and treatment files of various diseases are used as the key reference direction.

1989. Tian Meiyun and Sun Jian are related to this case.Based on this judgment, Gu Feifei first visited Feng Bing's home, but his wife said that she did not know Tian Meiyun and his wife, nor had she heard her husband mention it.Afterwards, Gu Feifei went to Longtou Village to find the village director, because she noticed that the village director had mentioned that Tian Meiyun's father, Tian Weimin, had died of illness in the previous records. Could this disease be related to thallium poisoning?She came here specially to let the village director recall what disease Tian Weimin had and the exact time of death.The village director recalled it carefully, and asked a few elderly people of the same age in the village committee, and the result was: "I really don't know exactly what disease I got. I only heard that it was terminally ill. When I died, it was probably November 11. moon."

After clarifying the key direction of medical records review, and locking in the identity of the patient and the approximate time of treatment, the scope of the file review was reduced to a relatively small size, and the work was basically done with half the effort.

This medical record records: when Tian Weimin went to see a doctor, he had symptoms of digestive system bleeding, limb paralysis, and severe damage to the central nervous system, followed by fainting and convulsions. .The disease indicated in the medical records was "infectious polyradiculoneuritis" (that is, Guillain-Barré syndrome), and the signature of the attending doctor was "Feng Bing".

To be honest, Tian Weimin's symptoms at that time were similar to those diagnosed by Feng Bing.Especially in those days, thallium poisoning was very rare, and perhaps the entire medical community in Mingzhu City did not know much about it. Even today, misdiagnosis still occurs, so even if Feng Bing really misdiagnosed, he should have done it unintentionally. .

Of course, as far as the symptoms themselves are concerned, Gu Feifei cannot conclusively determine that Tian Weimin died of thallium poisoning because it is no longer possible to obtain test materials for testing. She can only rely on relevant clues to make a comprehensive judgment.Inspired by the unsolved case of thallium poisoning, Jiang Qingshan first investigated the Chemistry Department of Pearl University of Science and Technology, and specifically asked about the storage of thallium in the department and the people who might be exposed to thallium. Through such a way to obtain thallium element.Based on this, Gu Feifei believes that Ai Xiaomei will definitely achieve something in the Polytechnic University!

With the cooperation of the University of Science and Technology, Ai Xiaomei consulted the graduation book of the Department of Chemistry of the school, and found no clues of intersection with anyone in Tian Meiyun's gang.Ai Xiaomei did not give up, took the photos of the members of the gang, and asked the teachers in the department to confirm one by one. In the end, the sky paid off. A female professor who stayed at the school in 87 recognized Tian Meiyun. She said that Hetian Meiyun is A classmate, but Tian Meiyun dropped out of school due to family changes shortly after entering the junior year...

Then, under the premise that "Tian Weimin died in 1989 and was murdered by poisoning", the investigation returned to the old question: How did Jiang Qingshan know about this suspected poisoning case?Have you filed a case before?With such a question in mind, Team Zhang went to check the case files of the year, but there was nothing at all, but he accidentally discovered another case related to Tian Meiyun, but Tian Meiyun was the "victim" in that case.

The case happened on the evening of Saturday, January 1989, 1 (the five-day work week was not implemented in that year). Tian Meiyun, a 7-year-old female college student studying in the second year of undergraduate chemistry at the Pearl University of Technology, returned from school to her hometown in Longtou Village in the suburbs. Missed at home while spending the weekend with his father Tian Weimin.

Two days later, late at night, Tian Weimin's home phone rang.On the other end of the phone was a strange man who claimed that he had kidnapped Tian Meiyun and asked Tian Weimin to prepare 20 yuan as a ransom. The specific time and place of payment would be notified later, and he threatened to tear up the ticket if Tian Weimin was found to call the police.

After thinking twice, Tian Weimin still called the police. He had already informed the police of his daughter's disappearance.At that time, Jiang Qingshan was the leader of the major case team, and he led the establishment of the special case team.Due to the backward technology at that time, it was impossible to track the phone information, so the task force basically carried out the investigation according to the routine kidnapping investigation process—sent some police officers to Tian Weimin’s house quietly, waiting for the blackmail call to come again, and instructing Tian Weimin how to communicate with the kidnappers, so as to Obtain effective clues; secretly investigate Tian Weimin's suspects who have had unpleasant experiences in social and business contacts, and go deep into Tian Meiyun's school to search for suspects who may commit crimes; issue internal investigation reports to the police stations of each sub-bureau, and pay attention to suspicious residents within the jurisdiction , the focus is on rental housing and residents with criminal records...

After more than ten days, Tian Meiyun was still nowhere to be seen, and the kidnappers did not call again. Based on past experience, the task force thought it was more ominous than good.But at that midnight, the courtyard door of Tian Weimin's house was knocked violently. Tian Weimin and the left-behind police officers opened the courtyard door together, and saw Tian Meiyun with disheveled hair and naked clothes; The kind driver I met on the road drove her back.

Immediately, Tian Meiyun was taken to the hospital for injury examination and questioned by the police.But the strange thing is that Tian Meiyun claimed that she couldn't recall the whole incident, including the kidnappers and the place of detention. She only remembered running desperately on the road for a long time.Asking the truck driver who took her home, he could only give the place where he met Tian Meiyun, and he didn't know anything about the rest.The task force then searched for suspicious dwellings within a few kilometers around this location, but finally returned without success.

One can imagine the bewilderment of the task force at the time.At first they thought that Tian Meiyun was just temporarily unstable, but they didn't expect that she still insisted on the original statement after more than ten days.The task force couldn't help questioning Tian Meiyun, but they couldn't find out her motives for covering up the kidnappers, especially since the injury test showed that she had indeed been subjected to inhuman abuse.

The forensic report showed that Tian Meiyun's wrists and ankles had obvious restraint marks, and her lower body was seriously injured, which was not only caused by continuous violent rape, but also had been manipulated by other hard objects, and infection had already appeared. If he seeks medical attention sooner, he may lose his fertility; moreover, his breasts, buttocks, and back have many marks of being burned by cigarette butts. The browbones on both sides were cracked due to punching or blunt force blows, and the cheekbones were so swollen that they were almost disfigured.

After seeing this forensic report, it would be inhumane to suspect the victim again, and it is impossible to imagine any motive worthy of Tian Meiyun's sacrifice.In the end, based on the circumstances of the case and Tian Meiyun's performance, the forensic doctor can only explain it with a rare disease.

The forensic doctor explained: "Tian Meiyun may suffer from 'selective amnesia'. This kind of disease is mostly caused by the fact that the patient cannot bear the pressure and injury that followed after suffering a major setback, so he chooses to escape in an evasive way. The method is to erase it from memory. In theory, memory can be restored, but the time cannot be determined. It is possible in one day, one month, one year, or even several years. Some people say that memory can be awakened through hypnotherapy, But there is no precedent in this country.”

The interpretation of the forensic doctor made the task force headed by Jiang Qingshan a little relieved. They turned their attention to the truck driver who carried Tian Meiyun home. After such an investigation, they really found that the truck driver was not a good guy: his name is Sun Jian, 30 years old at the time, his parents died early, lived alone, and drove a truck in a foundry run by a relative.According to the relative's introduction: Sun Jian is a man who loves leisure and hates work, is greedy for women, and likes to hang out with dubious men and women in society; he was almost called to the police for fraud, and later he pieced together and sold some The items left behind were only able to escape by paying the other party in private; they were not serious at work on weekdays, and they often did not see people for a long time.That relative was more nostalgic, and for the sake of his dead parents, he had no choice but to turn a blind eye and give him a meal.

With Sun Jian's character, it is not surprising that he targeted Tian Weimin, who was well-known in the construction industry in Mingzhu City at that time and had a lot of money. Moreover, he had a crime scene, a means of transportation to cover the crime, and it can be said that he also had a certain amount of criminal experience. , is worth further investigation.Later, the task force searched his residence and found obvious traces of cleaning, but he said that the tap water pipe in his home burst, causing water to flood the whole house, so he cleaned it up carefully.However, due to the severe damage at the scene, the task force finally found no criminal evidence and could only exclude him from the case.

No longer investigating Sun Jian, finding no evidence is only one aspect, in fact, the key is Tian Meiyun's attitude: she has repeatedly stated to the task force that Sun Jian is her benefactor, and no matter what happened to her, it has nothing to do with Sun Jian.Jiang Qingshan consulted the forensic doctor on this issue: "If Tian Meiyun really forgot the whole process of being kidnapped, would he also forget the kidnapper's appearance?" The forensic doctor could not give a definite answer, because there was no such case before. However, judging by his personal common sense, the possibility is unlikely.Jiang Qingshan thought about it too, even if Tian Meiyun really forgot, Sun Jian didn't have the courage to face her openly.

Since then, the task force has successively investigated several suspects who had business affairs with Tian Weimin, but all of them ruled out the possibility of committing the crime, and the case records stop here. To this day, the kidnappers are still at large!

After reading the old case files, Team Zhang felt deeply: Although the kidnapping case has not been solved yet, it has played a role in explaining the current case.It explains a lot of problems, but it still doesn't answer how Team Jiang noticed Tian Weimin's illness back then.With this question in mind, Team Zhang found a senior criminal policeman who was involved in the kidnapping of Tian Meiyun and has now been transferred to the branch as the director. From him, Team Zhang finally got the answer.

According to the director of the branch bureau: Tian Meiyun's kidnapping case was finally an unsolved case, and Team Jiang has always been worried about it, not only because the case was too bizarre, but more importantly, there were two capable generals in the team who had followed Team Jiang for many years. In the process of investigating the kidnapping case, a car accident happened and both died.Jiang Dui has always had a lingering thought in his heart, thinking that only by solving the case can he comfort the heroic spirit of the sacrificed brother. Even after the investigation of the case gradually cooled down, he still paid attention to the lives of Tian Weimin and Tian Meiyun's father and daughter. Therefore, he has a good friendship with Tian Weimin.

Of course, the subsequent development of the matter surprised everyone—Tian Meiyun actually fell in love with Sun Jian, and quickly reached the state of passionate love, and talked about marriage after only a few months of dating.Of course Tian Weimin strongly opposed it, and complained to Team Jiang in private that even if his daughter had been abused by bad guys, he would never be reconciled to her marrying a gangster with all kinds of bad deeds, not to mention that her daughter is still a college student who has not graduated.But the strange thing is that shortly thereafter, that is, in November of the same year, he was admitted to the hospital due to a sudden emergency, and died soon after.Team Jiang was very puzzled by this, suspecting that Tian Meiyun and Sun Jian jointly killed Tian Weimin, and went to the hospital to investigate in person to learn more about his condition, but the attending physician said that Tian Weimin died of illness and had nothing to do with the murder.Team Jiang did not give up, and took the hospital's diagnosis to consult the forensic doctor. The forensic doctor did not raise any objections in the end, so Team Jiang had no choice but to let go in the face of the evidence.After Tian Weimin's funeral, Tian Meiyun applied to drop out of school and took over her father's business. In February of the new year, she impatiently married Sun Jian...

When the information from the three aspects was cross-summarized to Han Yin, his tense face finally relaxed, and then he showed a smile that he hadn't seen for a long time.All the doubts were resolved, and he even found out who the kidnapper who kidnapped Tian Meiyun was!As for the evidence, it depends on who betrays the first, Tian Meiyun and Sun Jian.

Han Yin can imagine Tian Meiyun's reaction when he heard "thallium poisoning" and Sun Jian heard the two key words "kidnapping and extortion". There will be a "dog eats dog" situation.

Back at the academy, Han Yin, who had regained his identity as a teacher and stood in the lecture hall, was more calm in his thoughts and mentality. He shared the case he just handled in Mingzhu City with his students in a clear and logical manner:
Let's continue our discussion today following the topic of the previous class: the so-called hostage complex, also known as Stockholm syndrome, refers to the fact that the victim of a crime develops feelings of respect, dependence, and admiration for the perpetrator, and even actively assists the perpetrator to escape the law. Punish and continue to commit crimes.

Numerous cases in the past have shown that such delicate emotional relationships were created unconsciously by the perpetrators.However, the case in Mingzhu City was tricky because several consecutive cases were carefully planned, and the perpetrator established such a relationship premeditatedly, so as to control some victims and make them become accomplices and money-gathering tools to continue committing crimes.

Speaking of this, students will definitely ask, what kind of person can comprehend the essence of Stockholm Syndrome to such an extent?Must be a recidivist with a lot of criminal experience, right?On the contrary, this person has no criminal experience, she was even a victim in a kidnapping case - she is a woman, named Tian Meiyun, she admitted that a series of crimes were planned and led by her, and the inspiration came from the man who later became her husband The experience of Sun Jian kidnapping her.

Just after the New Year's Day in 1989, Sun Jian, who had been trying to make a lot of money through illegal means, read a report in the newspaper about Tian Weimin, a local inspirational builder. The report also introduced his family, mainly some of his daughter Tian Meiyun. information.Sun Jian became malicious because of this, and after several days of planning, he kidnapped Tian Meiyun, who was studying in a local university at the time, on a weekend, and then raped and tortured Tian Meiyun inhumanely at his residence, and at the same time lodged a complaint with Tian Weimin through a public phone. Extortion demand for ransom.But soon, being alert by nature, he discovered that Tian Weimin called the police, so he tortured Tian Meiyun even more brutally.After almost a week, he decided to find an opportunity to kill and silence.

Perhaps it was because Tian Meiyun was aware of the crisis of her life, and deliberately gradually made Sun Jian feel that she did not seem to be struggling as before, and even when Sun Jian gave her food or water, she would show a very grateful look, And there are moves to cater to Sun Jian in terms of sex.Although Sun Jian was still vigilant at the time, he had to admit that Tian Meiyun not only made him feel the physical pleasure, but also gave him a psychological sense of accomplishment of completely controlling others.So he was a little bit reluctant or didn't want to kill as soon as possible, so he kept Tian Meiyun's life for a few more days. Unexpectedly, Tian Meiyun became more and more docile, and even took the initiative to express his love for Sun Jian, and proposed a plan to hide the truth—she Pretend to have amnesia, so that the police have no way to deal with the kidnapping case, and at the same time let Sun Jian enter her life circle as a benefactor, and then look for opportunities for the two to get married.

Speaking of this, the students should have been able to feel that Tian Meiyun's series of actions are typical manifestations of Stockholm syndrome.Moreover, the "poison" in her was so deep that she finally used the opportunity of doing experiments in the school laboratory to quietly steal a large amount of solvent containing thallium, and put it into her father's water glass, causing her father to be poisoned to death.At that time, neither the medical profession nor the police had heard of this poisoning method, and finally made a wrong judgment, which allowed Tian Meiyun and Sun Jian to escape unscathed.Tian Meiyun, whose hands were stained with his father's blood, became even more devoted to Sun Jian from then on.

A few years ago, the two people who took over Tian Weimin's construction business eventually brought down the company due to poor management. With their son in his early 20s, they sadly returned to live in an old rural house and started a series of crazy crimes since then.The original intention of their first crime was actually very simple, which was to press for debts.Because of the triangular debt, Tian Meiyun's family of three went to the door to collect debts from Wu Delu, who was also in debt. After no results, they detained Wu Delu and Song Shuangshuang in frustration and abused them.According to Tian Meiyun's account: On the one hand, they wanted to see whether Wu Delu had left unknown life-saving money through the method of imprisonment and abuse; and the deeper reason was to use this to vent the inner imbalance caused by the unbearable reality. anger.It was also the familiar scene that made Tian Meiyun think of the experience of being kidnapped by Sun Jian, which led her to take the attitude of a bystander for the first time to comprehensively examine herself from the victim to the perpetrator who poisoned her own father to death. The mental journey of becoming husband and wife with the kidnapper.Unfortunately, like many victims of Stockholm Syndrome, even if Tian Meiyun understood the essence of this relationship, she did not have the courage to break free from this relationship, except that she herself had been involved in a murder case, and more importantly, she was used to it. In order to depend on such a relationship to survive.Regarding this point, there are many examples around us: for example, we often see some beggars with deformed bodies in the downtown or on the roadside. The purpose of such a disaster is of course to earn the sympathy of passers-by with their physical disabilities, so as to make money.In essence, they also belong to the relationship between the victim and the perpetrator, but when the victim feels that he cannot survive on his own terms, and the perpetrator can provide him with a way of survival, a kind of relationship with the perpetrator will gradually arise. The injurer has the mentality of sharing fate, regards the injurer's future as his own future, and regards the injurer's safety as his own.As a result, they adopt an "us against them" attitude and feel insecure about the rescuer.

The same goes for Tian Meiyun. Not only did she not resent Sun Jian, but she summed up a set of criminal patterns of mind control from her own experience of being victimized, and extended and perfected it.

First, the victim must truly feel that his life is being threatened.At this point, besides letting her son Sun Duo act as a ruthless killer, Tian Meiyun will also use practical examples to deter the victims. The most intuitive example is that she instructed Liu Yao to show the dead bodies under the floor to the Wang sisters.

Second, she wants the victim to understand that escape is impossible.Therefore, she would remove all the clothes of the victims, imprison them naked, and obey the arrangements for eating, drinking, sleeping, and sleeping. Any disobedience would incur corporal punishment by Sun Duo.

Third, during the process of detention, sometimes small favors are given to the victim.At this point, Tian Meiyun adopts a differentiated approach. She will deliberately do some considerate actions for victims who are easy to accept psychological hints: for example, between men and women, she will choose women; for example, between the elderly and young people, she will choose the latter……

Fourth, block outside information and control the victim's thoughts.To put it bluntly, this is brainwashing. In a space where information is blocked, the theory that victims must be attached and respected to survive is repeatedly instilled.

Tian Meiyun’s four summaries actually coincide with the four common characteristics of Stockholm Syndrome analyzed by several of our classmates in the previous class.And Tian Meiyun's excellence is that these characteristics are organically kneaded together to play a complementary role-she exposes all the victims naked to each other's sight. It is conceivable that whether it is a couple Between mother and child, father and daughter, or mother and daughter, facing this naked "candid treatment", what a sense of humiliation they will have in their hearts, and their self-esteem will become numb over time.This is exactly what Tian Meiyun wants. She wants to use this method to completely destroy the self-esteem that the victim should have, and then completely change the victim's worldview and values ​​​​through brainwashing, thereby depriving them of the ability to think independently, and then through different methods. In the way of grace, the victims who are prone to hostage complex will be included as accomplices, while the remaining victims will be set up as opposites, and the former will be induced to hurt the latter, and finally the former will be firmly controlled, allowing them to give willingly and without trace. property.

Han Yin finally said: "Now this case has been hyped up by the press. It is generally reported that Tian Meiyun has superpowers to control people's minds, and she was nicknamed 'Mind Killer'. The truth is that Tian Meiyun used It’s just a hostage complex, or to be more precise—any animal can be domesticated, including humans!”
