Night's Watch 2: Dark Potential

Chapter 9 The One-legged Monkey

Because most people in the world don't believe in truth, but take the initiative to believe in what they want to be true.No matter how wide the eyes of such a person are, they can't actually see anything.

"You mean to ask Zimo to look at the gait, right?" Xiao Lang put his arm on Ling Mo's shoulder and said, "You deduced from the gait that those three people were not the murderers, and you really did. Now these three people are relieved, and finally don't have to be 'harassed' by our police."

"The gait may not be fixed." Ling Mo silently dodged Xiao Lang's arm, and said, "Since it was a well-planned crime, and it was not clear where the police were monitoring the location at the beginning, the murderer would definitely fake his gait." So, as I said just now, I rely on Zimo's intuition."

"What is intuition?" Xiao Lang couldn't believe it.

"Intuition, or the sixth sense, seems to be something you can't touch or see, but it's really useful." Ling Mo said, "At least when the landslide happened, Zimo's intuition came into play. It works. Although our science can’t explain intuition with complete basis, it does exist. There are always phenomena that science can’t explain.”

"It's always unreliable to rely on intuition to solve a case." Xiao Lang said.

"Of course it's unreliable." Ling Mo said, "We don't rely on intuition to solve the case, but rely on intuition to find clues, and finally use clues to find evidence to solve the case. Many criminal policemen have intuition, and many cases are finally solved. The clues are all derived from the intuition of the criminal police. In the future, you can find out by reading more criminal case records. However, Zimo’s intuition is different from theirs. Her intuition has a wider range and is more acute.”

"I'm so impressed by you, I want to see what's different." Xiao Lang said indifferently, "You said, since someone planted a frame, he just concluded that the police will use those three people to settle the case?"

"I don't know." Ling Mo said, "Maybe they thought the police would torture to extract a confession. Don't many people on the Internet agree that the police will definitely torture to extract a confession?"

"Or a zero confession." Xiao Lang pursed his lips and nodded.

"Convictions with zero confessions have strict requirements for evidence, and there must be a complete chain of evidence." Ling Mo said, "Now that we are in the process of rule of law, it is no problem to convict cases with zero confessions. Unjust cases rarely occur because of zero confessions, but the police need to do their best to complete the connection of all chains of evidence."

"It's just the murderer's wishful thinking, right? He thinks that the public prosecutor's law will decide the case hastily." Xiao Lang said contemptuously.

"Yes, now the public prosecutor and the judge are responsible for the case for life, so naturally they will not decide the case hastily. Without a complete chain of evidence, the judge will not try and convict if there is any reasonable doubt." Ling Mo said.

"It really looks like it was said on the Internet that the law is all about protecting criminals." Xiao Lang shook his head.

"It is impossible to protect the legitimate rights and interests of innocent people without protecting the legitimate rights and interests of criminal suspects." Ling Mo said, "If you want judicial justice, you must first put judicial power in a cage. dark abyss."

"Why does it feel like you're about to become a poet?" Xiao Lang scratched his head and said.

While talking, the two had already reached the gate of the data laboratory of the Night Watchers organization.

"Dangdang, how's it going?" Ling Mo pushed open the door, and Tang Dangdang sat alone in front of a console with more than a dozen screens, moving the mouse quickly.

"Called Dangdang again, did you call Dangdang?" Unconvinced, Xiao Lang stretched out his hand to cover Ling Mo's mouth, turned his head and said to Tang Dangdang with a smile: "Dangdang's hands are so fast! Don't you It’s a pity to go to e-sports! If you play LOL (the abbreviation of a certain online game), how can those teams matter!”

Ling Mo moved Xiao Lang's big hand away from his mouth with great difficulty, picked up a tissue on the table and wiped the corner of his mouth, and asked, "Is there too much data?"

Tang Dangdang said without raising his head: "There are more than I imagined. At present, in addition to the camera probe in Zhao Yuan's house, there are eleven police surveillance camera probes. Because we don't know the murderer's walking route, Eleven Every intersection monitoring needs to be analyzed. In addition, the camera probe in Zhao Yuan’s house has a large amount of data. There are dozens of people in their house who come to consult every day. Moreover, we don’t have a clear time frame. You can't find a completely overlapping portrait of a human face, so it's very difficult."

"That's true." Ling Mo said, "If you want to step up the pace, it's safest to extend the time to one month."

"There is no way for a month." Tang Dangdang said, "I took a look, except that Zhao Yuan's camera probe has nearly two months of data, because the police camera probe is not a traffic police capture camera probe, but a security bayonet monitoring, automatic coverage It’s the kind, so it’s only about 23 days. From the day when the crime was committed, 23 days of images can be extracted, and there will be no more images going forward.”

"I think more than 20 days is enough." Ling Mo said, "If the murderer acts quickly, a week is enough. However, to be on the safe side, you still need to observe for 23 days."

"Well, there is still a lot of data." Tang Dangdang stopped his hands, with a troubled expression on his face, "Do you have any good ideas?"

"You said that you stepped on the spot, then look for those thieves." Xiao Lang laughed at the side.

"You're talking nonsense again." Tang Dangdang said angrily.

Ling Mo pondered for a while, then said: "No, Xiao Lang is not talking nonsense."

This conclusion was beyond Xiao Lang's expectation, he scratched the back of his head embarrassingly.

"The person who steps on the site must be different from other people. He wants to obtain information but does not want to expose himself. This kind of psychology will definitely be reflected in his expression." Ling Mo said.

"Well, to put it bluntly, who, like you, can read minds? Why don't you watch it instead of Dangdang, because Dangdang watches too much computer, it's not good for your eyes." Xiao Lang said.

"Since the public security surveillance can't see the appearance and expression, then we start with the surveillance of Zhao Yuan's house that was taken at close range." Ling Mo said to Tang Dangdang, "You said that dozens of people come to the window of Zhao Yuan's house for consultation every day. So even if it was pushed to a month ago, there were not many people in total. In order to prevent the murderer from making up, all you have to do is to find people who look similar, wear similar clothes, or look around and have ghosts in their hearts Among these people, someone should have seen the camera probe, or looked in the direction of the camera probe."

"If you say so, dare you let Dangdang watch the video?" Xiao Lang said angrily, "You are really lazy! Then what are you going to do next? Are you investigating Zhao Yuan's conflicting relationship?"

"I'm afraid the contradictory relationship is not so easy to investigate." Ling Mo spread his hands and said, "I read the transcripts. In the past three years, the police have spent a lot of thought in order to rule out the possibility of other people and other motives. Investigating [-] people, no one reported that Zhao Yuan and his wife had conflicts with other people. The eyes of the masses are discerning. This Zhao Yuan should be a good man. Then this kind of incident that triggered murder , It must be a small incident that no one else noticed."

"Then you watch the surveillance and let our eldest miss rest." Xiao Lang said.

"No, with so much video data, it's most efficient for me to handle it!" Tang Dangdang's hands returned to the mouse and keyboard.

"We have more important tasks, let Zimo help Dangdang later." Ling Mo pointed to Xiao Lang, "Let's go to Bei'an."

"Oh, are you really going?" Xiao Lang said excitedly, "The fishball ramen there is the best, miss, let's go eat together!"

"We didn't go to eat." Ling Mo shook his head and left the data room first, while Tang Dangdang tapped on the keyboard quickly with his head down.

Xiao Lang looked left and right, and said to Tang Dangdang: "Miss, don't worry, I'll pack it back for you to eat."

The Evidence Room of the Institute of Criminal Science and Technology, Criminal Police Detachment, Bei'an Public Security Bureau.

Nie Zhixuan held a laser pointer in his mechanical hand, and pointed at a whiteboard covered with maps: "Our method of extracting physical evidence is generally to restore the criminal's action trajectory through on-site analysis and reconstruction, and then analyze it in his actions. Extraction may be carried out at places where there may be traces and physical evidence left on the trajectory. For the Zhao Yuan case, it was also extracted according to this model at the beginning, and no valuable traces and physical evidence were found. However, now that we have a new understanding of the case, now It is also necessary for us to revisit the process of extracting physical evidence."

"The biggest problem now is that the entire area of ​​the scene has been demolished." Xiang Ming, a forensic doctor at the Bei'an Public Security Bureau, said, "It would be great if the night watchmen could intervene in this case earlier. We have preserved nearly It took two years, but in the end, because of the government’s overall demolition requirements, the appeal to keep the site was abandoned.”

"This is indeed a problem that restricts us from working again." Ling Mo said, "We can only start from the physical evidence that has been extracted to the physical evidence room, hoping to make new discoveries."

"Anyway, let's try it." There was a paper box in front of Xiao Lang, which was filled with fish ball ramen, and he said vaguely while stuffing the noodles into his mouth.

"Let me now revisit our new thinking." Nie Zhixuan said, "The murderer has repeatedly stepped on the site and clarified the situation and surveillance situation. He chose a time of 06:30 on Tuesday afternoon, when there were no neighbors and pedestrians were few. The murderer first lurked at the light box. After confirming that there was no one around, he cut off the wires of the light box. At this time, the light box and the camera probe stopped power supply, but it did not affect the power supply in the hotel, so the victim did not pay attention. Then, The murderer walked into the courtyard of the hotel. At the concierge, he deceived the gate of the concierge by using the pretext of staying in the hotel, and took advantage of his unpreparedness to use murder weapons to control Zhao Yuan and his wife. After threatening Fang Kexia to tie up Zhao Yuan, he He personally bound Fang Kexia. After the binding was completed, Feng Qi suddenly returned to the hotel in advance. At this time, the murderer who could not hide had a slight fight with Feng Qi. But after all, he was armed with a murder weapon and might have advantages in physical fitness and martial arts. Feng Qi was also under control. There was an unexpected situation, which was a great stimulus to the murderer. He frantically tied up Feng Qi with tape. Before the binding was completed, Li Jiangjiang and his wife came back one after another. , controlled the couple one by one, and carried out crazy binding work. But after the binding was over, the murderer was a little at a loss. Because the signs of suffocation will not appear until the human body is in a state of suffocation for several minutes. Within a few minutes, the murderer He did not make any other actions. In the end, for some reason, the murderer made up his mind to kill and silence the people. After cutting open the necks of five people, he collected the five people's belongings in the room or with them, and discarded them in a certain place. Not far from the property, the murderer lurked and watched until he saw three people passing by together, picking up the property and dividing the spoils. After obtaining these information, the murderer returned to the scene, took his gloves and the three pairs of slippers on the scene Stained with blood, rummaged and walked around the scene, creating the illusion that three people were rummaging for belongings in slippers. After completing these, the murderer left the scene alone."

"During the whole process, the traces and physical evidence that may be left are..." Forensic doctor Xiang bit the pen holder, and said, "One is the place where the light box cut the wire, but we took the light box back, and there are obviously a lot of dust and layered glove marks, It shows that the murderer was wearing gloves to complete these actions. The second is the traces of fighting, walking and rummaging at the scene. Unfortunately, the scene has been demolished. Well, I don’t have the conditions to extract evidence. The third is the handbag used to store the stolen goods. After the three people divided the stolen goods, they discarded the handbag. Later, we organized the police to search in the surrounding garbage, but they couldn’t find it. Tape, this has been delivered to your Night's Watch."

"I checked, and there are no traces or evidence of any value," Ling Mo said.

"Furthermore, there are slippers at the scene." Forensic doctor Xiang said, "However, according to the test results of our DNA laboratory, there were no doubts."

"The main point of our visit this time is to come here for the slippers." Ling Mo said, "The DNA inspection department did not find the DNA of the three suspects at the beginning, so the inspection report and map were not attached."

"We have all archives here," said the forensic doctor.

Ling Mo nodded, and said: "What I want to say is that the conclusion reached by the DNA testing technology back then was that the DNA of the three suspects was not found, not that no DNA was found, and there is an essential difference between the two. "

"This is true. After all, in the past three years, we have not suspected others, and we have always confirmed in our hearts that these three people did it."

"If there is someone else's DNA, wouldn't there be a clue?" Ling Mo said, "Anyone will sweat, especially after frequent activities at the scene, there will definitely be DNA left over."

"That's the theory," said the forensic doctor Xiang. "However, the DNA test cannot theoretically deduce the result. If we find the DNA, it means that the criminal left DNA. If we can't find it, it means that he didn't leave it. It can't be said, theoretically. If you stay, you will definitely stay.”

"Then, have you found the DNA of anyone other than the deceased?" Xiao Lang stopped chewing and asked anxiously.

"Yes." Forensic doctor Xiang said, "The three pairs of slippers are all old cotton slippers, which are for guests, and this kind of slippers cannot be cleaned like plastic slippers. Know how many people have mixed DNA."

"The analysis of mixed DNA is really difficult." Nie Zhixuan said, "It is difficult for us to decompose so much adulterated DNA data one by one, and even if we decompose it, we don't know who is the murderer."

"Yes, we can only find the DNA of existing suspects from these complex DNA data, so as to play a role in exclusion." Forensic doctor Xiang said.

"It's really impossible to find the murderer on a pair of slippers." Ling Mo smiled slightly, "However, our murderer wore three pairs of slippers by himself, and the distance traveled by each pair of slippers was not enough." close."

"Ah, I see." Nie Zhixuan suddenly realized, "Ling Mo's idea is really good. From the complex DNA data contained in the three pairs of slippers, find common points. If you pick out all the common points, the biological characteristics of the murderer It's clear!"

"What a good idea! Why didn't I think of it?" Forensic doctor Xiang patted his head and said.

"Ling Mo is quite smart." Xiao Lang looked forward with anticipation, and continued to suck his ramen with peace of mind.

"We have all the data from that year in our database." Forensic Doctor Xiang said, "Now we just need to retrieve the data, and Forensic Doctor Nie and I will spend a little time analyzing it, and we will get results."

"Then I'll leave it to you." Ling Mo poked Xiao Lang's arm, and said, "Now invite some colleagues who are familiar with the case to accompany us to the scene."

"The scene is now a piece of rubble." Forensic doctor Xiang said.

"That's right, I haven't finished eating, what a waste!" Xiao Lang stopped the flying chopsticks and said reluctantly.

"I don't know what I can find, but since we're here, why don't you go and experience it yourself," Ling Mo said.

"Okay then, I'll send a car right away." Forensic doctor Xiang said, "The terrain there is complicated, and your car is too heavy, so I'm afraid it will be inconvenient."

"Hey, it's here, wake up." Ling Mo pushed Xiao Lang who was sleeping soundly next to him to wake up.

"Ah? It's here?" Xiao Lang wiped the drool from his mouth and said, "I'm sleepy when I'm full."

"Our Bei'an City covers an area of ​​more than 1000 square kilometers. It is almost [-] kilometers from the bureau to the municipal hospital." The driving policeman of the Bei'an Public Security Bureau said, "It is almost the northernmost to the southernmost part of the city. distance."

"Here, how long has it been since it was demolished?" Ling Mo sat in the parked car without moving, looking at the mess outside the window.

"Since the murder happened, the demolition has been planned." The policeman pointed to the east side of the municipal hospital in the distance, and said, "Look, there is a new resettlement community, which was built last year, and the residents here have received compensation for demolition. The house was moved there. The demolition started here, which must have happened at the beginning of this year."

"It will be 2018 in a few days, so this place has been demolished for a year." Ling Mo said.

"Yes, this area may be used by the government as a government affairs center." The policeman said, "After all, there have been vicious murders, and the developer's asking price is not high."

Ling Mo nodded, opened the door and got out of the car. A gust of cold wind blew in, causing Ling Mo to shrink his neck unconsciously.It can be seen that this large area is really only separated by a road from the hospital, but it is already a large area of ​​rubble at this time, and the "prosperous scene" of the past cannot be seen here.If there had been a house, the boundaries of the area should have been visible, but now that there is rubble, the boundaries are unclear.Ling Mo knew that under such circumstances, asking the police to point out the exact location of the murder scene was really harsh.

"It's been demolished for a year, and there are still people cooking?" Xiao Lang pointed to the distance and said, "Smoke is coming out there."

"How is this possible?" The policeman laughed dumbly.

"Don't believe it? Don't believe me, drive over there and have a look." Seeing that the policeman didn't believe him, Xiao Lang turned around and pulled Ling Mo into the car.Ling Mo was depressed because he couldn't do anything when he arrived at the scene. He heard Xiao Lang's words at this time, he believed in Xiao Lang's sensory ability, so it was a glimmer of hope, so he hurriedly called the police to drive to Xiao Lang. Drive where Lang pointed.

Fortunately, the criminal police detachment dispatched an off-road vehicle. After bumping crazily on the rubble for more than ten minutes, the vehicle finally stopped at the prompt of "Stop" from Xiao Lang.

Xiao Lang jumped down first, looked around for a while, and then helped the policeman open the door of the driver's cab, dragged the policeman out of the car, and said, "Look, look, there's a large area of ​​dead grass scorched."

"Oh, it's really amazing, I admire it." The policeman who was lifted up by Xiao Lang like a chicken, praised insincerely at this time.

2
Ling Mo was not distracted by the pile of scorched withered grass, what he noticed was that there were dozens of piles of burning ashes neatly arranged beside the withered grass.At a glance, you can't see the end, if you don't pay attention, it will be extraordinarily spectacular if you notice it.

"What's with these neat piles of ashes?" Ling Mo pointed to the row of ashes, then leaned over and picked up a little with his fingers, saying, "The burning time is not very long."

The policeman was also stunned for a while, and then suddenly realized: "Ah, that's what happened. Whether it's our Bei'an or your Nan'an, the customs and habits are to lighten the winter solstice and emphasize Qingming. According to the custom, the winter solstice is also to commemorate the dead ancestors. The day when people burn paper and pay homage."

"You said these ashes are memorial offerings?" Xiao Lang asked in surprise, "Aren't the ashes going to the cemetery to sweep graves?"

The policeman smiled, picked up a bamboo pole from the ground, turned over the pile of ashes in front of him, and said, "Look, there are some charred fish and rice in the pile of ashes, isn't this a sacrifice? The residents in this area were originally rural residents, and their deceased relatives were cremated and buried in their own fields. Later, this piece of farmland was expropriated by the government, and the government also organized special personnel to carry out inspections of the cemeteries in the field. Unfortunately, there is no cemetery in the south of Bei’an City, so all the graves in the field have been moved to Xiaowenshan Cemetery in the west, which is, um, [-] kilometers away.”

"Understood." Xiao Lang said, "Because it's too far away, so I burned the paper nearby."

"Yes, except that the residents here will go to the cemetery to sweep graves every year during the Qingming Festival. During the Hungry Ghost Festival and the Winter Solstice, they will burn a few stacks of paper and serve a few small dishes on the wall nearby. After burning the paper, put a few dishes The small dishes are poured into the flames, and then a small hanging firecracker is set off, and the whole memorial ceremony is completed." The policeman introduced.

"Well, that's true." Ling Mo said, "In Nan'an, many immigrants pay homage to their ancestors in this way. There will be several fire alarms every year because of this incident."

"It's true. Fortunately, this area has become ruins, so even if the dead grass is burned, it can burn for a few days, and it will not cause any harm." The policeman said.

"Winter Solstice, that was last week." Xiao Lang counted with his fingers, "From today, five days? Four days? Four or five days."

"The winter solstice is a solar term, but before and after the winter solstice, sacrifices are still held on the same day. Everyone's family has its own different habits, so two or three days before and after the winter solstice, people will come here to burn paper." The police said, "Oh, yes When this area was not demolished in the past two years, people burned paper at the base of the wall near the site every Qingming and Winter Solstice. This shows that Zhao Yuan and his wife still have a good reputation."

"Burning paper for Zhao Yuan and his wife?" Ling Mo asked alertly.

"Uh, in short, let's burn it to a few people who died unjustly." The policeman said.

"I know it's difficult, but now it's really necessary to ask you to help find the exact location of Zhao Yuan's house." Ling Mo said to the policeman, "Well, to be precise, we are now looking for the ruins of Zhao Yuan's house."

"The specific location is difficult, but I think I can find the general location." The policeman said, "Three years ago, I soaked in this area every day for three months."

"That's great, it's enough to have an approximate location." Ling Mo looked at the sky where night was about to fall, and said, "But hurry up, or our clairvoyance may fail."

"Clairvoyance? Are you talking about me?" Xiao Lang asked, pointing to his nose.

"After our colleagues give us a general location, we will rely on you to find the pile of ashes." After Ling Mo finished speaking, he dragged Xiao Lang to follow the police.At this time, the police had already identified the direction, and walked deep into the rubble with one foot deep and the other shallow.

"Pile of ashes? Isn't the pile of ashes right here? Hey, hey, don't pull me, I have a high center of gravity, and I can't find the balance." Xiao Lang bluffed.

"If I remember correctly, it should be almost here." After walking on the rubble for 5 minutes, the policeman stopped and said.

"Is there?" Ling Mo asked Xiao Lang beside him.

"Yes, isn't that what it is?" Xiao Lang pointed to the west.

100 meters to the west, there seems to be a sooty gray ash pile.Ling Mo continued to move forward, and when he came to this pile of lonely ashes, he squatted down, imitating the policemen, and picked up the ashes with a bamboo pole, but there were no sacrificial offerings inside.The ashes burned completely, and the shape of the burning objects could not be seen.Ling Mo picked up a little ashes with his fingers, put it next to Xiao Lang's nose, and said, "How many days do you think it's been burning?"

"I'm not a police dog!" Xiao Lang opened Ling Mo's hand and said, "I think it's about three days. Just guessing, it's not a few days anyway."

"There was rain the day before the winter solstice, but the ashes in this place did not get wet." The policeman said, "It doesn't look so fresh anymore, so it must have been burned in the few days from the day of the winter solstice to yesterday. That's about the same."

"The monitoring here is gone too, right?" Ling Mo asked.

"Anyway, if you want to enter this area, if you don't have transportation, you must first go to the bus stop in front of the hospital, where there is surveillance." The police said.

"A dead horse is a living horse doctor." Ling Mo smiled confidently, "I need surveillance images of bus stops from the day of the winter solstice to yesterday."

"Look at what you mean, is it really the paper that was burned by the murderer?" Xiao Lang asked Ling Mo.

"I think so." Ling Mo replied briefly and firmly.

"Indeed." Xiao Lang agreed, "You said that other people's sacrifices should be done at the edge of the ruins. Anyway, the tombs are not here, and it is the same to burn paper wherever you go. There is only a lonely pile of ashes here, not specially for sacrifices. What about the victim?"

"But it's about 100 meters away from the actual location of the scene." The policeman said, "And could it be something done by the family of the deceased?"

"It is precisely because of the deviation that it shows that the mourners only know the exact location of the scene." Ling Mo said, "As for the family, if I remember correctly, the old Zhao Yuan and his wife have no children, right? Relatives."

"After all, the old couple are very good people, could it be..." the policeman said.

"Whether he is the murderer or not, we have to investigate if there are clues." Xiao Lang couldn't stand the police's moaning, "Isn't it said that a dead horse is a living horse doctor?"

"Actually, our previous analysis was that after controlling Zhao Yuan and his wife, the murderer controlled the other three people one after another." Ling Mo interrupted Xiao Lang, and patiently explained, "These three people The sudden appearance of the murderer was unexpected by the murderer. Therefore, the murderer showed obvious panic in the way of binding. This is one. Second, the murderer executed five people only a few minutes after completing the binding action, which shows At least he has experienced a psychological struggle. Combining these two points, the murderer should feel guilty about the three people other than Zhao Yuan and his wife. Since he feels guilty, he may come to pay homage. This is a common sense psychological analysis."

"From the murderer's point of view, there are so many people paying homage here every year, and he will not be discovered." Xiao Lang added.

"If that's the case, I'll arrange to get the video." The policeman said a little embarrassedly, "It should be no problem. Fortunately, our public security surveillance can be traced back to more than half a month ago."

"It's 23 days." Ling Mo smiled slightly, "Thank you for your hard work. It's almost dark, and it's time for us to go back and see the work results of Brother Nie and Forensic Doctor Xiang."

When Ling Mo and Xiao Lang opened the door to enter the DNA laboratory of the Criminal Police Detachment of Bei'an Public Security Bureau, the printer in front of Nie Zhixuan was spitting out a long atlas.Nie Zhixuan held a section of the atlas with his mechanical hand, and skillfully tore off the tail of the atlas from the printer with his other hand.

"Looks like you've got it done?" Ling Mo walked behind Nie Zhixuan in three steps in two.

Nie Zhixuan frowned and looked at the atlas for a long time, and said, "No accident, this is the DNA of our suspect."

"In other words, this DNA type is found on the three pairs of slippers at the scene?" Xiao Lang asked.

Nie Zhixuan nodded.

"Isn't that all right?" Xiao Lang jumped three feet high, "There were more than a dozen pairs of slippers in the cabinet at the scene, and the three pairs related to the crime all had the DNA of this person, and this person was not Zhao Yuan and him. wife, who else could it be if it wasn’t the murderer?”

"Indeed, the DNA data discovered by this method is very likely to belong to the murderer." Nie Zhixuan said, "But..."

"But what?" Xiao Lang leaned down, looked into Nie Zhixuan's eyes, and asked eagerly.

"However, this person is a woman." Nie Zhixuan said.

The word "woman" came out of Nie Zhixuan's mouth, and got into Ling Mo's ears. For some reason, these two words caused Ling Mo's mind to flash that women's knitting wool with a big peony flower Clothes.

"Woman? It's impossible for a woman." Xiao Lang said, "She killed five of them by herself, but she still controlled them first and then killed them. Why is a woman such a man?"

"She has a murder weapon, and she may have received special training. She cannot negate objective results because of her gender." Ling Mo said, "From an objective point of view, there is no other way to explain the fact that the same woman's DNA appears in three pairs of slippers. fact."

"Our opponent is actually a woman." Xiao Lang squeezed his knuckles.

"Should I call Dangdang to check?" Nie Zhixuan said, "This will narrow their scope of investigation."

"No, we need their further verification before we can confirm this conclusion." Ling Mo said.

"Let me tell you, on the surface, you are so affectionate, but when it's time to feel sorry for her, you will be cruel again. If you have the ability, go watch the video!" Xiao Lang protested, waving his fists.

Ling Mo ignored Xiao Lang, shook hands with Forensic Doctor Xiang with a smile, and said, "It's getting dark, we should go back. We have gained a lot this time, thank you for your support."

"No, no, it's obvious that you are supporting us." Forensic doctor Xiang said pleasantly, "This fishbone has been stuck in our throat for three years. Now we see the possibility of removing it. We are really looking forward to it."

"Let's work together." Nie Zhixuan said, "In order for the evil to have nowhere to hide."

"Let's go after dinner." Forensic Doctor Xiang seemed to hit it off with Nie Zhixuan, and enthusiastically asked to stay.

"That's fine." Xiao Lang sat back on the chair again, "The fish ball ramen downstairs you have is not bad, don't bother too much, just eat that."

"Three years have passed, and now we can't afford to wait." Ling Mo stretched out his hand to pull Xiao Lang, "Let's go back earlier, after all, there are still three hours away."

"That's not less than ten minutes away." Xiao Lang protested.

"Didn't you eat it just now?" Nie Zhixuan said.

"That was a few hours ago. You are a forensic doctor, don't you know? How many hours did your stomach empty?" Xiao Lang said.

"I'll go buy it now." Forensic doctor Xiang looked for the wallet in the drawer.

"Brother Xiang, don't listen to him, he's always out of shape." Nie Zhixuan patted the back of Xiao Lang's head with a playful smile.

"Why am I out of shape?" Xiao Lang was dragged up from the chair by Ling Mo and Nie Zhixuan, reluctantly moving, "Then wait for me for 5 minutes, okay, I'll go downstairs to pack two bowls .”

Ling Mo and Nie Zhixuan couldn't hold back Xiao Lang in the end, and they still gave him 5 minutes to pack the fish ball ramen.Xiao Lang held two bowls of fish ball ramen in his arms with a happy smile, sat in the jack on the return journey, and said, "Let me tell you, if you two don't eat it, you will definitely regret it. The fish ball ramen here is not only It’s delicious, and the service is super good! Look at their packing boxes, such a thick plastic lunch box, with its own heat preservation effect. Let me tell you, believe it or not, it’s a cold day, I’ll take them home without using a microwave You can eat it hot."

"It's not that we don't eat it, it's that you didn't buy it for us." Nie Zhixuan said with a smile while sitting in the passenger cab.

"I'm not hungry." Ling Mo said.

"How can I compare with you, you don't eat fireworks in the world." Xiao Lang grinned and turned to Nie Zhixuan, "It's not that I'm stingy, this guy said he wasn't hungry, otherwise I would definitely buy it for you two. Although A bowl of 50 yuan is not cheap, but with my moral character, I will definitely buy it for you two."

Nie Zhixuan shook his head and laughed dumbly.

"There's a lot of nonsense, hug your face, don't blame me if you mess up." Ling Mo drove the car roaring on the highway.

Ling Mo underestimated the packaging ability of Bei'an Fish Ball Ramen.When Jack drove into the parking garage of the Night Watchers Organization, Ling Mo found that Xiao Lang, who was sitting in the back seat, was already sound asleep.The handbag in his arms also fell to the ground.Xiao Lang jumped anxiously when Ling Mo woke him up, but soon he found that the ramen in the lunch box was intact and kept warm.

Approaching the compound of the Night Watchers, Ling Mo and his group saw that the lights were still on on the top floor of the Little Red Building from a distance. Tang Dangdang and Cheng Zimo were obviously working overtime for complicated video images.

Xiao Lang walked into the gate of the laboratory with his handbag in his hands and his head shrunk as if playing a prank, and tiptoed towards the backs of the two girls.

At this moment, the two girls had already stopped their work, Tang Dangdang stared at the many photos on the screen with his hands resting on his cheeks, and Cheng Zimo was leaning on the swivel chair with his legs resting on the operating table, closing his eyes. Eyes, pinching the bridge of the nose with fingers.

When Xiao Lang was approaching Tang Dangdang, Cheng Zimo still kept her eyes closed, but said, "Dangdang, Xiao Lang wants to scare you."

Tang Dangdang glanced back at Xiao Lang, then turned to look at the screen intently.Xiao Lang suddenly felt bored, but luckily he still had two bowls of fish ball ramen in his hands.

"It's time for supper!" Xiao Lang put the handbag in front of Tang Dangdang, with a satisfied expression on his face, "Do I keep my word?"

Tang Dangdang happily took out the lunch box from the handbag, handed one to Cheng Zimo, opened one himself, and said, "I'm just hungry."

"I'm hungry too, thank you Xiao Lang." Before Xiao Lang could react, Cheng Zimo stuffed a mouthful into his mouth, "Well, it's not bad!"

Xiao Lang didn't take back the hand that was stretched out to stop him for a long time, he swallowed and said, "That's, mine..."

"Aren't you full yet?" Ling Mo knocked Xiao Lang's hand off, and said to the two girls who were feasting, "Eat quickly, and we'll check the situation after eating."

"I really am. My eyes are almost blind. Now I can deeply understand how hard it is." Cheng Zimo finished his fish ball ramen and resumed his previous posture.

"Is there no soup left? If you want to be a delicate girl, you have to eat less." Xiao Lang looked at the lunch box and said disappointedly.

"Zimo, what's your conclusion?" Ling Mo asked.

Cheng Zimo opened his eyes and stared at Ling Mo. After a while, the two said at the same time, "Woman."

"Okay, with the support of your point of view, it basically shows that our judgment is correct." Ling Mo was a little excited.

"How did you see that?" Xiao Lang was curious.

"However..." Cheng Zimo seemed uneasy about his discovery and hesitated.

"Don't hesitate, just say it directly," Ling Mo said.

"If I were to draw a conclusion now, I'm afraid I can only draw the conclusion of 'woman'." Cheng Zimo said, "After watching the video for so long, I began to doubt my own judgment."

"It's because it's not alone." Ling Mo smiled slightly.

"How do you know?" Cheng Zimo was a little surprised, "You know everything?"

"I don't know, it's just that we have guessed about this before." Ling Mo said, "Let's talk about it."

"According to what Xiao Lang said, we started to watch from the surveillance of Zhao Yuan's house." Cheng Zimo said slowly, "When we saw the case three days before the incident, we had some clues. Because there was a woman at the porter's window When talking with Zhao Yuan, there was an obvious movement of looking at the camera. According to this standard, I continued to watch the video of the previous half a month, and sure enough, I found that several people had looked around. If you put If the actions of these people are traced according to the timeline, the first time it seems to be looking at the environment inside the house, the second time it is looking at the environment in the courtyard, the third time it is looking for something on the spot, and the fourth time it is obviously looking around. When I found the camera probe on the roof, the fifth time should be to confirm whether there is only one camera probe, and the sixth time should be to confirm that the connection cable of the camera probe is connected to the outside of the house. I took screenshots of these six faces, you guys Look."

Six women's faces appeared on the computer screen, with completely different appearances.

"Wow, criminal group? Send six people to set foot on the site, and then send only one person to kill?" Xiao Lang said.

"We have considered this issue." Cheng Zimo played with her chewing gum box and said, "Our Dangdang is still super smart. When I found these faces, Dangdang based on the clothes of these six people. , I found the walking trajectories of these six people in the public security surveillance. Interestingly, the walking trajectories of these six people are all the same, and all three public security surveillance cameras recorded their backs. I think it is one person.”

"Alone?" Xiao Lang was taken aback.

"If it's six different people, it's impossible for all of them to follow the same path when they arrive at such a well-connected place." Ling Mo concluded, "This is the inertial thinking in a person's subconscious."

"Let me show you the backs of these six people first." Tang Dangdang opened more than ten windows on different display screens.After Tang Dangdang's fingertips made quick and frequent contact with the keyboard, images appeared in more than ten windows.Judging from the clothes, there are six women in the picture, some with short hair, some with long hair, some with ponytails, and some with shawl hair.All six of them passed through the public security surveillance alone, and each segment lasted only a few seconds.

"After reading these, I feel that I am alone." Cheng Zimo said.

"Where is he alone?" Xiao Lang said, "Look at the man in the yellow windbreaker, he is clearly a lame man."

"I've said before that since I've repeatedly stepped on the spot, I can't rule out the possibility of disguising my gait." Ling Mo said, "This is the fifth time this yellow windbreaker has stepped on the spot. It is very likely that he has already learned about the situation of the police surveillance, so he deliberately pretended to be a gait." Don't you think the man is limping unnaturally?"

"Miss, can you tell it's a person?" Xiao Lang said unconvinced.

"I don't know." Tang Dangdang muttered, "But the figures and heights of these six people are quite similar."

"I have no basis, just intuition." Cheng Zimo said.

"Intuition again." Xiao Lang spread his hands, obviously not convinced.

"Replay." Ling Mo touched his chin and said.

The video was replayed twenty times on more than a dozen screens, and Ling Mo's eyes went up and down.

"I support Zimo's judgment." Ling Mo broke the temporary tranquility.

Regardless of their appearance, the backs of the six people in the video have different hairstyles, but their bodies are still very similar.The gait of the back figure corresponding to the clothes that appeared twice in Zhao Yuan's home surveillance was exactly the same.In the back four times, although the gait is different, there are obvious signs of camouflage.

This is the conclusion Ling Mo came to.Based on all the previous situations, Ling Mo can make a judgment from a macro perspective.

"Gait analysis is already an old subject. According to more than 20 indicators, the final determination of a person's gait condition can be an individual's gait characteristics, physiological or pathological gait, or reflect a person's psychology. "Ling Mo said, "Although I have learned from the teacher, I am not proficient. However, at the very least, I can still tell whether it is a disguise or not."

"The camouflaged gait, apart from being detectable, can it be identified the same as the normal gait?" Cheng Zimo asked.

Ling Mo shook his head and said, "Even if we want to compare, we still need to have a video of walking a long distance. The video data we currently have is too short."

"To be honest, I still feel a bit mysterious." Xiao Lang still didn't quite believe it, "Those six people obviously have six face shapes and six facial features, okay? Makeup can't change the face shape and facial features at all. .It can’t be the 'Disguise Technique' reappearing in the Jianghu, right?"

A gleam of light suddenly flashed in Ling Mo's eyes.

"Do you still remember the few cases we encountered before?" Ling Mo said, "It is impossible for the minibus to pick up people halfway. Since there are other people's blood, unless a person has two kinds of DNA; there is no passage for criminals to enter and exit the scene. Unless someone has a superior jumping ability and jumps directly from the window without touching the window sill. These two cases do seem unbelievable, but the seemingly impossible part is the final answer."

"Disguise? Yirong is not the same as before?" Nie Zhixuan said, "The disguise in the novel is all fake. How can a person wear a mask on his face to look like someone else? The shape of the face is different. Even with special effects makeup, you can see the clues."

"I don't believe that someone can change into another person's appearance at will, but it is still possible to change one's own appearance randomly instead of imitating it. Although I can't tell the scientific basis, I think that compared with In the previous two cases, this possibility is more likely." Ling Mo said, "Since there is no other choice, we might as well choose an impossible reasoning possibility to try."

"If someone can really change her appearance, then even if we know that the murderer has repeatedly stepped on the spot, even if there are surveillance images of the scene, she will not be able to find her original appearance in the surveillance. In this case, the murderer will indeed not care about surveillance. It's gone." Cheng Zimo said, "That's why the murderer didn't destroy the computer at the scene: he wouldn't expose himself, and he could confuse the police's line of sight."

"Although this problem seems inexplicable now, I believe there will be a scientific explanation in the end." Ling Mo said, "Combined with the cases we have handled before, the criminal investigation technology is so advanced now that we can get it in our hands. These are strange cases that seem unexplainable on the surface. In fact, to sum up, as long as we stick to the essential issues, bypass those variable factors, and continue to investigate even if it does not conform to common sense, we can solve the case. Because our opponents are different, our methods are naturally different."

"Then stop worrying about the scientific nature of 'disguise'." Cheng Zimo asked, "How do you know it's a woman?"

"DNA." Ling Mo briefly explained.

"You found the murderer's DNA?" Tang Dangdang said in surprise.

"No accident, that's the murderer's DNA." Ling Mo nodded.

"Also, we extracted some videos. We think that the murderer may have felt guilty about the deceased, and went to the scene to pay homage to the deceased a few days ago around the winter solstice." Nie Zhixuan handed a USB flash drive to Tang Dangdang.

"Want to watch the video again." Cheng Zimo said in a tearful voice.

"There is a time frame this time." Nie Zhixuan smiled, "From the day of the winter solstice to two days before, there are only three or four days of video."

"I'll watch it with you." Xiao Lang dragged the chair forward and said to Tang Dangdang.

The images of the two camera probes at the front and back of the bus stop were simultaneously displayed on the two display screens. Tang Dangdang used eight times the playback speed to play several days of video.Soon, in the video on the night of the winter solstice, a short-haired woman appeared on the phone, getting off the bus while she was on the phone.

"Wait." After seeing this video, Xiao Lang and Cheng Zimo yelled almost at the same time.

This was beyond Ling Mo's expectation.Ling Mo signaled Tang Dangdang to replay this video, and played it frame by frame.A short-haired woman wearing an orange long down jacket and dark blue sneakers, with a red plastic bag in one hand and a mobile phone in the other, got off a No. 7 bus and stood on the platform and stared in the direction of the ruins After a while, I walked towards the direction of the ruins.Fortunately, the lights on the bus stop are sufficient, and there is no reflection or discoloration.

"You mean, this person didn't know that the ruins had been demolished, and he was surprised when he got out of the car, and then he knew the direction before heading to the scene?" Ling Mo asked.

"I can't see the expression, so I'm not sure about it." Cheng Zimo said, "I just simply think that this person's feelings are consistent with our suspect."

"Intuition again?" Xiao Lang laughed.

Cheng Zimo nodded seriously.

"Could this red plastic bag contain sacrificial supplies?" Nie Zhixuan said.

"Okay, now I trust your intuition." Xiao Lang didn't answer Nie Zhixuan, but said directly to Cheng Zimo.

"What did you discover again?" Nie Zhixuan patted Xiao Lang's shoulder.

"Dangdang, enlarge this person's right hand." Xiao Lang said.

The woman in the video is holding a mobile phone in her right hand and is talking on the phone by her ear.The picture was magnified little by little by Tang Dangdang, and it seemed to gradually become less and less clear.When the woman's side face and right hand fill the entire screen, almost nothing can be seen.

"Hey? Why are you so unclear? This is wrong." Xiao Lang said.

"The pixels are not enough." Tang Dangdang gradually made the photo smaller.

"Stop, stop!" Xiao Lang shouted again when the picture shrank to a certain extent.

"What's wrong?" Ling Mo stared at the picture.

"What color light is the phone?" Xiao Lang asked, "Can you see this clearly?"

"Lan Guang, your eyes are really sharp." Tang Dangdang admired.

"How big is the phone?" Xiao Lang asked again.

No one answered.

Xiao Lang took out his mobile phone from his pocket, gestured and said: "What era is it now? It will be 2018 soon! How can anyone use this kind of phone for the elderly? And no matter how disguised this woman is, she is still young, right? Ling Mo, tell me, isn't one's gait revealing one's age?"

"Over 20 years old." Ling Mo said.

"That's right! Have you seen it, an old phone! A mobile phone much smaller than the palm of your hand!" Xiao Lang was looking for a sense of identity with everyone, "Do you still remember 'Ghost Rider'? 'Ghost Rider' uses a Nokia 8310 Ah! This should be similar! Blu-ray! Small mobile phone!"

"'Ghost Rider'?" Ling Mo was taken aback, "Does she have anything to do with 'Ghost Rider'?"

"Huh? That's right, is he with the 'Ghost Rider'?" Xiao Lang also turned around, "But the style of acting is not the same. And this woman killed a good guy whom everyone praises."

"No, no, I think their acting styles are very similar!" Nie Zhixuan said, "After Ling Mo came to the judgment of disguise, I couldn't figure it out: Since she can disguise, why should she pretend? Now It seems that, firstly, like 'Ghost Rider', she subconsciously has the habit of disguising after committing crimes. Second, like 'Ghost Rider', she is proficient in police investigation methods. She knows that the police investigation of cases is definitely not only Just looking at the appearance, you can also find out the body through monitoring, as well as the investigation of a series of traces and evidence such as DNA, fingerprints, footprints, and other more advanced investigative methods. Therefore, even if she can change her appearance, she chose to disguise the scene , Misleading the police's investigative vision, planting the blame on a few unlucky ghosts, so as to escape legal sanctions. This can be explained. Moreover, the two clues of Zimo and Xiao Lang merge into one, so this person is very suspicious. "

"I support Brother Nie's point of view." Ling Mo briefly concluded.

"Are these two people really a team?" Xiao Lang said, "One is lurking in Nan'an and the other is in Bei'an? But the time difference is nearly three years."

"What Xiao Lang said really reminded me." Ling Mo said, "Dangdang, can you deduce the hiding place of this woman on the bus based on her movements? I remember Cao Yun was like this discovered."

"It's definitely possible." Tang Dangdang said.

"Then I'll find a forensic doctor to trace the trajectory now." Nie Zhixuan took out his mobile phone.

It was getting closer and closer to the discovery of the suspect's lair, and every member of the night watchman had an expression of excitement on his face.The same is true for Xiang Ming, who is hundreds of kilometers away. Even though it was already 11:30 in the middle of the night, after Nie Zhixuan called him, he readily agreed to the request and promised to meet him in the next morning. Give Nie Zhixuan an answer.

From this point of view, the hard work of the night was carried out by colleagues from the Criminal Division of the Bei'an Public Security Bureau.Except for Xiao Lang, who has been sleeping intermittently for a long time, the members of the Night Watch organization have been working for a long time, and they really need to rest.So, after Nie Zhixuan and Doctor Xiang explained clearly, everyone returned to the dormitory to rest.

Xiao Lang woke up in the dormitory, it was already dawn, he looked at his watch, the hour hand pointed to 08:30.Xiao Lang didn't know why his "natural awakening" came so early, it was obviously not his style.Maybe it was because of his long life in the police force that he forcibly adjusted his biological clock.

Since it was so early, Xiao Lang still wanted to sleep for a while, but he accidentally caught a glimpse of the bed opposite, which was Ling Mo's bed. "This kid ran away so early? Where did he go?" Xiao Lang secretly recalled what happened yesterday.After Tang Dangdang handed over the work to his colleagues in the Bei'an City Bureau, all he had to do was wait for the result. They might promise to give a result this morning, and if nothing unexpected happened, the result should come out.If the results come out, Tang Dangdang will definitely go to the laboratory to study and judge.Did Ling Mo go too?

Thinking of this, Xiao Lang jumped up from the bed, put on his clothes, and ran into the laboratory.

Pushing open the door of the laboratory, as expected, Ling Mo and Tang Dangdang were staring at the screen in front of them intently.However, Xiao Lang was too worried, because Nie Zhixuan was also sitting at the side, playing with his mechanical hand.

"It's so early." Xiao Lang said awkwardly, scratching the back of his head.

"08:30 is still early?" Nie Zhixuan greeted Xiao Lang with a smile, "We will watch the video at six o'clock."

"Then did you see anything?" Seeing that the embarrassing atmosphere had eased, Xiao Lang immediately regained his spirits.

"Xiang's forensic doctor found a colleague from the graphic investigation department and retrieved the surveillance on the bus the suspect was riding on." Nie Zhixuan said, "Although she can't see her face clearly, but she is wearing such colorful clothes. So it's easier to track the trajectory."

"She didn't expect us to find the reason in the ashes at this time." Xiao Lang said proudly, "Unfortunately, we can't see her face clearly, otherwise this must be her real face."

"We're looking for it too." Nie Zhixuan said, "It's under surveillance in our Nan'an City."

After all, the Night Watcher organization settled down in Nan'an, and Xiao Wentian is the director of the Nan'an Public Security Bureau, so the computer in the Night Watcher organization's data laboratory is directly connected to the database monitored by the Municipal Public Security Bureau. After performing relevant legal procedures, Read it anytime.

"Come to Nan'an?" Xiao Lang said in surprise.

"According to the suspect's special clothing, colleagues from the Bei'an City Bureau deduced that the suspect boarded the bus directly from the Bei'an City Coach Station based on the route of the bus. It was confirmed that the suspect arrived at the station directly by a long-distance bus from another place, so the police found the driver of the bus the suspect was riding on overnight. Unfortunately, we checked the system and found that this kind of express bus was purchased by car and did not register an ID card. Yes, and unfortunately, the surveillance inside the bus was broken. But one thing is certain, this bus is a long-distance bus from Nan'an City to Bei'an City. Although we know the approximate time when the suspect boarded the bus, but We still haven’t found the video of the suspect when he was riding the bus. So we worked hard on her return to Nan’an, estimated the approximate time, and soon found the video of the suspect at a bus stop outside the Nan’an coach station. .” Nie Zhixuan said.

"Then it depends on where she goes after getting off the car!" Xiao Lang said eagerly, "She arrived in Nan'an very late at night, right? She must have gone to her place! Find her place, find her place."

"What do you need to say? Isn't this right here?" Tang Dangdang blamed Xiao Lang, "You are so noisy."

"Then we have to quarrel." Xiao Lang said, "I've been idle for a long time! It's my job to arrest people! I'm here to work, can I not be happy?"

"This bus is going along Huaihe Road." Ling Mo was watching the video while drawing a picture on paper, muttering, "She got off at Chaoshuimen, but the bus platform here is not monitored. "

"Did you lose it? You won't lose it, right?" Xiao Lang was so anxious that he rubbed his hands behind Ling Mo.

"Don't make noise." After Ling Mo finished speaking, he continued to draw on the paper.

After a while, the white paper in front of Ling Mo was already densely drawn.Ling Mo bit his pen and stared at it for a while, pointed to the areas marked on the paper, and said, "If you are going to areas A and C, then when the suspect chose to transfer just now, he should not have taken the 114 bus. car. So this time, she must be going to area B."

"Okay, let me take a look at some camera probes in this area." Tang Dangdang flipped through the timetable and said, "Well, it should be after 45:[-] p.m. in this area."

The screen on the display screen flipped rapidly.

"Hey, hey, stop, stop, there, there!" Xiao Lang pointed to a streetlight on the empty street in the surveillance.Sure enough, an orange figure flashed under the street lamp.

"It should be." Ling Mo suppressed his joy and said, "See where she goes."

The orange figure passed the street lights and stopped at the door of a shop not far away, obviously knocking on the door.After a while, the door of the shop opened, and an orange figure flashed into the house.

"What shop, what shop?" Xiao Lang wished he could start drawing his gun now.

"Let's check it out." Ling Mo took out the police pass, and checked the location on the screen.

After a while, Ling Mo raised his head, his excitement was beyond words, this is really rare on Ling Mo's face who usually doesn't talk much, and even less smiles.

Ling Mo said: "Meifu hairdressing! Now the three clues are brought together!"

"Is it really a barbershop? Is it really related to 'Ghost Rider'?" Xiao Lang was equally excited.

"No matter what the relationship is, at least it seems that the person we suspect should be good." Ling Mo said.

"What do you mean?" Tang Dangdang and Nie Zhixuan asked in unison, both of them were at a loss.

After all, Tang Dangdang and Nie Zhixuan did not participate in the process of extracting broken hair from the knitted sweater and deducing that the person who killed "Ghost Rider" and blamed Cao Yun might be working in a barber shop.

"However, didn't you just say that the suspect and the 'Ghost Rider' were together?" Xiao Lang thought about it and thought it was wrong, and said, "Why is this suspect killing the 'Ghost Rider' again now?" 'Woolen cloth?"

"It's just a deduction now." Ling Mo's cheeks flushed with excitement, "As long as we can catch the person, we can obtain more evidence, and maybe the answer will be revealed."

"Then don't say anything." Xiao Lang touched his waist subconsciously, and found that he didn't have a pistol with him, "Notify the special police detachment! Follow me to arrest people."

After speaking, Xiao Lang turned his head and walked towards the gate.Ling Mo grabbed Xiao Lang, but he staggered and almost fell.

"What are you in a hurry for?" Ling Mo regained his footing and said, "Don't forget, our suspect may change his appearance. Since you don't know her real appearance, who are you going to arrest?"

"Uh, I almost forgot about this." Xiao Lang patted himself on the forehead.

"Is there anything you can do?" The impatient Xiao Lang had already gone to the jack to get the body armor and put it on. He had a Type 92 pistol in his arms, and he was as anxious as an ant on a hot pot beside Ling Mo. ——Tuan Tuan Zhuan, "If you have no choice, go to Lao Xiao or your teacher."

"My dad is on vacation, and he won't be back until a few days later." Tang Dangdang said.

"Since the team leader has given us the task, we still have to ask the mentor, which is really unreasonable." Nie Zhixuan said.

Ling Mo nodded, approving Nie Zhixuan's thoughts.Suddenly, he seemed to have a flash of inspiration and said: "The suspect's real situation is that he has short hair, right? Zimo also has short hair."

"You mean?" Cheng Zimo touched his short hair and said.

"You are a wind catcher, and you should be able to pretend to lurk." Ling Mo said, "I want you to pretend to be a suspect."

"That's impossible. The suspect can't be disguised in her usual residence. It must be her original appearance. And we don't know what her original appearance is, and there is no reference even for special effects makeup." .” Cheng Zimo said.

"There's no need for makeup skills." Ling Mo said, "We're just going to find out what's true. It's best if we can find something. If we can't find it, we won't be exposed."

"Understood. Now we have the suspect's back, pace and clothing. I will prepare according to this and see if I can go to the store to 'knock a shirt'." Cheng Zimo nodded and threw a piece of chewing gum into his mouth , Said, "I'm going to buy clothes according to the information in the surveillance video."

The connotation of makeup investigation is relatively rich. In addition to preventing being discovered by criminal suspects, sometimes, a good makeup investigation can play the role of "alarming the snake".And Cheng Zimo's idea now is to use the "make-up-like" method he learned in the Night Watcher organization to "surprise the snake".Even if the suspect finds out, it will not be exposed, but once the snake is startled, the other party can be forced from the dark to the bright.

This method of "striking the grass and scaring the snake" is actually very simple. It is to imitate the known information, block the unknown information, and let others use the familiar "known information" to obtain the clues that investigators want.Using this specific case, because the surveillance captured the suspect's clothing, hairstyle, back and steps completely, after Tang Dangdang's color correction, the general outline of the suspect can already be known.What I don’t know, or what I can’t imitate, is the face of the suspect. Then, by buying clothes that are as similar as possible, Cheng Zimo imitates the steps of the suspect’s back and covers his face, which may arouse other people who are familiar with the suspect. Cognition, so as to have topics or directly inquire about information about suspects.

Needless to say about clothing, just buy it directly, but imitating the pace is a very technical job.

When people are standing and walking, the displacement movement, gravity, and friction degree of the force on the ground are different, so the morphological changes caused by the interaction between the feet and the ground are also different. This feature is relatively stable and can be used for people. Direct perception by the sensory organs, this is the characteristic of steps.The perception of gait characteristics is definitely not just a visual perception.As Cheng Zimo, who has a strong sixth sense, his ability to imitate steps is naturally superior to ordinary people because of his perception.With his innate ability, coupled with the relevant training of the Windcatcher, Cheng Zimo has firmly grasped the characteristics of step imitation.As long as the difference in body shape is not too far away, it is difficult for ordinary people to distinguish this imitation through perception.

"Can you go alone? It's easy to be exposed when there are so many people." Ling Mo asked.

"I waded through the gravity bomb alone, a barber shop is nothing." Cheng Zimo walked out of the laboratory door without looking back.

"How can that be done!" Xiao Lang said, "Is the situation different twice? Last time if there was no other way, I, the ambusher, went in after all!"

Ling Mo lowered his head and thought for a while. He felt that it was basically impossible not to let Xiao Lang go under such circumstances. With Xiao Lang's stubborn character, he would definitely make a fuss with the night watchman mentor.Secondly, this suspect can fight five against one, and his skills cannot be underestimated. With Xiao Lang's protection, Cheng Zimo's safety is guaranteed.After weighing the matter, Ling Mo pointed to the bulletproof vest on Xiao Lang's body and said, "Then you can't go wearing this."

"Of course, it's an undercover mission. I'm not stupid." Xiao Lang suddenly smiled, "Cheng Zimo, wait for me!"

Cheng Zimo was wearing a long orange down jacket, dark blue sneakers, and a pair of big sunglasses. He got off the jack side by side with Xiao Lang, and walked straight to the Mobil hair salon.

This is a fairly large hairdressing and styling shop. Looking at the facility sign at the entrance, I found that the shop has three floors. The first floor is the general hairdressing and styling area, the second floor is the SPA (leisure spa) private room, and the third floor is the small cafeteria , bathroom and two staff quarters.When entering the hair salon, Cheng Zimo paid special attention to the surrounding camera probes.The result of the observation disappointed Cheng Zimo: Except for the camera probe that captured the suspect's back, there were no other camera probes, neither public security surveillance nor private surveillance.And the hair salon has four doors, that is to say, as long as the suspect chooses other doors to go in and out, there is no trace of her at all.Cheng Zimo knew that Tang Dangdang, who was still observing and monitoring, would find nothing.

Cheng Zimo and Xiao Lang pushed the door and entered, triggering the induction of an electric fortune cat at the door, and the cat said, "Welcome."

Hearing the sound, a little girl with bangs ran over enthusiastically.She was taken aback when she saw the two, and then secretly called out: "Sister Xiaoxiao?"

Knowing that the effect had been achieved, Cheng Zimo immediately took off his glasses and looked at Qi Liuhai.

Qi Liuhai was taken aback for another moment, speaking with a southern accent, he said, "I'm sorry, you two, I mistook you. Are you doing hair styling or spa?"

"Haircut." Cheng Zimo said.

"SPA." Xiao Lang said at the same time.

The two looked at each other, Xiao Lang said: "Okay, okay, listen to you, get a haircut."

Qi Liuhai glanced at Xiao Lang, his cheeks flushed, he covered his mouth and smiled and said, "Then who is the barber?"

"He." Cheng Zimo pointed at Xiao Lang.

"Her." Xiao Lang pointed at Cheng Zimo at the same time.

"This?" Qi Liuhai looked puzzled.

Xiao Lang touched his hair that he had just taken the time to take care of today, gritted his teeth, and said, "Okay, it's me."

"You guys are so interesting." Qi Liuhai directed Xiao Lang to wash his hair, and said, "This lady is yours..."

"Sister." Cheng Zimo said.

"Girlfriend." Xiao Lang said at the same time.

"Which show are you two playing?" Qi Liuhai laughed.

"Sister-brother love, is sister-brother love okay?" Xiao Lang smoothed things over, then lowered his head and whispered to Cheng Zimo, "Is there no tacit understanding at all?"

Cheng Zimo gave Xiao Lang a blank look, and sat on the swivel chair to flip through a hairdressing magazine, but his eyes observed the situation of the hairdressing salon through the reflection of the mirror in front of him.

Xiao Lang looked at his hair wet by Qi Liuhai with great reluctance, and said, "My girlfriend, does she look like your friend? I think you mistook someone from the beginning."

"Yeah, very similar." Qi Liuhai said while rubbing Xiao Lang's hair with shampoo, "So she lives in the same dorm as me."

"Really? Could it be my long-lost sister-in-law?" Xiao Lang grinned and said, "What's her last name?"

"Ah? I really don't know about that." Qi Liuhai said, "She never said her name, she only said that others called her 'Shan Xiao', so we all called her Sister Xiaoxiao."

"San Xiao?" Xiao Lang said, "Isn't San Xiao a toothbrush?"

Xiao Lang felt that Qi Liu Hai who was standing on top of his head was already trembling with laughter.

"You don't need to register your ID card to work in your shop?" Xiao Lang didn't know why this silly girl was having fun there all the time, so he quickly brought the topic back.

"Ah? I don't understand. Anyway, we haven't registered for a few years. Do we still need to register for part-time jobs?" Qi Liuhai said.

"I don't know about that, so I'll just ask." Xiao Lang noticed that Cheng Zimo's expression not far away was a little nervous, and realized that he couldn't be too straightforward, so he quickly smoothed things over and said, "Your toothbrush sister is here now. Where? Let me see if it resembles my girlfriend."

"You should have come two days earlier." Qi Liuhai said, "She resigned the day before yesterday, because she thinks the wages here are too low."

Xiao Lang immediately looked disappointed.

Cheng Zimo who was not far away obviously heard this too, so he came over and said, "Wash him up, don't worry about it."

Qi Liuhai looked puzzled again.

Xiao Lang quickly interrupted Cheng Zimo, and then asked Qi Liuhai: "Then have you recruited new people in your store these two days?"

As soon as Xiao Lang's words came out of his mouth, Cheng Zimo immediately realized his mistake.Because the suspect may have the ability to disguise, she can also pretend to resign, and then re-enter the store with a different face.If this was the case, several technicians around her might be suspects, and her eagerness would scare the snake away.From this point of view, Xiao Lang's question is still very necessary.

It can't be seen that Xiao Lang, who is usually joking and not in good shape, becomes thoughtful and cautious in his words and deeds once he enters the state of arrest.It was the same with the gravity bomb last time. If Xiao Lang hadn't discovered it in time, the scene would have quickly turned into a sea of ​​flames, and nothing could be found.Xiao Lang is really a strange person.

"No, we've all been working here for more than a year." Qi Liuhai seemed to sense the abnormal atmosphere, and answered truthfully.

"That's fine." Xiao Lang took the towel from Qi Liuhai, dried himself, and said, "Why don't we sit in your dormitory."

"She really left the day before yesterday and worked here for about two months." Qi Liuhai looked aggrieved, pointed to an empty bed board in the bedroom, and said, "The bedding is provided by the boss. After she left, The boss sent it to the laundromat for washing."

"The best physical evidence that can be extracted to DNA is gone." Cheng Zimo said with a bit of regret.

Xiao Lang sat on the empty bed, patted the bed next to him, and said to his bangs, "Don't be nervous, come and sit. There are only two of you in one dormitory?"

"Most people live in rented houses outside. Next door is the boys' dormitory. There are four of them. I live alone in our room." Qi Liuhai couldn't help being nervous.

After looking at the police IDs of Xiao Lang and Cheng Zimo in the dormitory, Qi Liuhai was taken aback, and immediately became stiff and uneasy from the relaxed and casual at the beginning.

"Did you find out that she took drugs?" Qi Liuhai said timidly.

"You know she takes drugs?" Cheng Zimo put his tone as lightly as possible, "It's okay, little sister, you can tell me everything you know. We all know it, but you just need to verify it."

"This, I also guessed." Qi Liuhai said, "When I went to work last time, there were too many customers, and the sisters were too busy. At that time, Sister Xiaoxiao didn't know where to go, so I responded to the boss's request. I came to the dormitory to look for her. The door of the dormitory was ajar at the time, so luckily I didn’t push the door open to come in. I saw through the crack of the door that she was holding a needle-like thing to pierce her arm, and she was still lying down after the piercing. Lie there for a while."

"Does she pierce often?"

"No, that was the only time I saw it." Qi Liuhai said, "Although Sister Xiaoxiao often asks for leave, the longest time we have been together is a week, and I haven't seen her get an injection. Well, she must be poisonous." The addiction is not deep."

"There is no such thing, little girl." Xiao Lang said pretending to be old-fashioned, "There is no such thing as a deep or deep drug addiction. Once you get addicted to drugs, your life will be useless."

"I know that." Qi Liuhai said, "so I didn't dare to go in. It's always bad to bump into other people's privacy. However, I saw her use that needle-like thing to pierce the bed board on the bed. That day, She seems to be in a bad mood."

"Really?" Xiao Lang didn't pay attention to this sentence, and then asked, "When did that happen?"

"Sister Xiaoxiao just came here not long ago, at the end of October or early November."

However, at this time, Cheng Zimo didn't care about the next question, but immediately pulled Xiao Lang away, knelt at the place where Xiao Lang was sitting just now, and observed the bottom of the upper bed.

This is an ordinary bunk bed, with some hairdressing supplies on the upper bunk, which is used as a warehouse.The height of the lower bunk is not high, so if a person leans on the head of the bed, the upper bunk is within reach.

Cheng Zimo said excitedly, "There is really a needle's eye. It's still a triangle!"

While talking, she kept wiping the eye of the needle with the "cotton swab for evidence collection" she carried with her, trying to extract some useful traces and evidence from the eye of the needle.

"The four clues are gathered." Xiao Lang pondered, "Have you noticed the appearance of the needle?"

Qi Liuhai shook his head.

Cheng Zimo took out his mobile phone from his pocket, first took a photo of the needle hole under the bed board, and then found a photo in the mobile phone.This photo was taken of the syringe that Cheng Zimo desperately took from Cao Yun's house when he was in distress at Cao Yun's house. There was still faint blood on it when Cheng Zimo stabbed Cao Yun.

"Is it the same?" Cheng Zimo asked.

"Probably the same, I really haven't noticed it." Qi Liuhai glanced at the phone and said.

"What kind of person is your sister Xiaoxiao?" Cheng Zimo asked.

"Seldom talk, very sensitive." Qi Liuhai said, "But she is very kind to me, and will take me to eat whatever I buy. It's just that I can't ask anything about her own history or family, and she ignores me when I ask. I did. But then I figured out that we only talk about the present and the future."

"What did you talk about?"

"That's too much, about what kind of man you like, which guest today looks ugly, etc." Qi Liuhai blushed.

"Anything in particular?"

"No."

"You said just now that you and Sister Xiaoxiao have been inseparable for a week, and you haven't noticed anything different about her?" Cheng Zimo asked.

"No, nothing special except talking a little less." Qi Liuhai said.

"In that week, we went to the bathroom and took a shower together?" Xiao Lang asked.

"The toilet is on the opposite side, and next door is the bathroom." Qi Liuhai said, "There are two shower heads in the bathroom, so we often take a shower together."

"Then, is her body different from others?" Xiao Lang asked.

Qi Liuhai blushed immediately, lowered his head and said, "Why do you ask this?"

It was only at this time that Xiao Lang came to his senses, and realized that it seemed inappropriate for him to ask such a question, so he said: "The police handle the case, do you know? This is the same as a doctor's physical examination, so don't think about it in a wrong way."

"When did I think about it in a wrong way? You asked...that question is too much." After Qi Liuhai finished speaking, he paused, and continued, "However, she has a tattoo here."

After finishing speaking, Qi Liuhai pointed to his chest.

"That's right, that's what I'm asking." Xiao Lang said, "What is it about?"

"Well, then I can't stare hard at that place." Qi Liuhai still lowered his head and said with a blushing face, "It looks like a monkey, but it seems to have only one foot."

"One foot?" Xiao Lang tilted his head thinking.

But with just such a tilt of his head, Xiao Lang noticed a trash can in a dark corner under the table in the dormitory, and there seemed to be something he had known before in the trash can.

"Then where did she go after she resigned, do you know?" Cheng Zimo asked.

"I don't know, she said that she might go wandering around the world." Qi Liuhai said, "She is a very free and easy person, I really envy her."

"Is there any other story about your sister Xiaoxiao?" Cheng Zimo asked.

Qi Liuhai thought for a while, shook his head, and said, "It's really gone. She is really a very ordinary person, just like all the technician sisters here. Did you really find out that she was a drug addict?" ?”

"Don't ask if you shouldn't. You have to keep all our conversations secret today." Cheng Zimo said to Qi Liu Hai with a smile.

"En." Qi Liu Hai nodded vigorously.

Seeing that the conversation was over, Xiao Lang moved to the side of the table, pointed to the trash can and said, "You haven't cleaned up this trash for several days, right?"

"How do you know?" Qi Liu Hai nodded dully, "I haven't lost it for a week, so there is no garbage in the first place."

"Of course I know, not only that, I also know that before your toothbrush sister resigned, she came back from outside and brought you fish ball ramen." Xiao Lang smiled slightly.

This surprised Qi Liuhai so much, she stared and said, "Wow, you guys really know everything!"

Xiao Lang bent down and pulled the garbage bag out of the trash can, pointed to the two thick thermal insulation plastic boxes inside, and said, "Look, don't you even throw out this garbage? Little sister, you are lazy."

Qi Liuhai lowered his head in embarrassment.

"Then tell me, of these two boxes of ramen, you ate the left half, or did you eat the last half?" Xiao Lang deliberately eased the atmosphere.

"I ate everything, it's really delicious." Qi Liuhai continued to feel embarrassed.

Xiao Lang winked at Cheng Zimo, and said to Qi Liuhai who was rubbing the corner of his clothes with his head down: "Then we won't bother, the surveillance in the store will be picked up by the police station later. In addition, I will take this garbage bag Take it out for you and throw it away. The garbage should be cleaned up frequently, and the girls' dormitory should look like a girls' dormitory."
