The professional quality of the male protagonist

When he went back the next day, Zhang Xuan deliberately brought the video he had obtained earlier, wanting to show it to Liao Qun.

As soon as he entered the door, Liao Qun looked at the two of them with such an expression, his eyes full of disgust.

Li Yancheng turned a blind eye and went to the side to fiddle with his photographic equipment. Zhang Xuan was a little thin-skinned and blushed, but he still did not forget his purpose of coming here.

He walked to Liao Qun's side, and then released the part of the video he got, and said, "Help me see if you can recover the video and see who is on it, except for the people involved at that time. In addition, there are 28 other people, one is the woman's boyfriend who has been cleared of suspicion, and the rest I want to see who they are."

"The video is a bit blurry. I'm afraid it will take some time to recover the characters. And looking at it like this, I may not be able to recover some people's faces." Liao Qun became interested when he heard Zhang Xuan's words, but he saw After the mother video, some people couldn't help frowning.

The quality of the video is very poor, and the picture of the video is very small, even if it takes a long time for him to recover some pictures, but no matter how detailed he is, there is nothing he can do.

"You try to see how many portraits you can recover. I will send these portraits to the family members of the victims to identify them and see if anyone can recognize them." Zhang Xuan said, "What happened in the video here I'll leave it to you, and I have to go back to the bureau. Before I left, I told Xia Xiaodong that they had pulled out all the video surveillance around Ma Qingsheng's house, and wanted to see if they could find a woman with a child inside. This clue, but since there is a school not far from that place, the scope of the investigation is a bit large, I have to go back and look."

"I'll go back first. Li Yancheng, when will you be able to go back?" Zhang Xuan came in a hurry and left in a hurry. He didn't have any luggage, and he was already standing at the door with his car keys when he was talking.

"In a few days, the filming in the county will never end." Li Yancheng lowered his head and sorted out the camera equipment.

"County?" Zhang Xuan followed him and walked out the door. He was a little surprised when he heard the place name, because he had only heard of this place name not long ago. After the woman broke up with her boyfriend, her boyfriend went there. county.

After the two went downstairs, they left separately. Li Yancheng continued his work, and Zhang Xuan returned to the police group to investigate another clue with Xia Xiaodong and the others.

After Li Yancheng suggested that the murderer might not be a person, but a woman with a child, their investigation direction has been on this line.

Although they don't have any conclusive clues yet, Zhang Xuan confirmed that this clue should not be wrong.

Ma Qingsheng was the second-to-last victim. His home happened to be in a residential area. This residential area was not remote, and there were many surveillance videos around. Zhang Xuan started the investigation with him as the main line.

In the day before Ma Qingsheng was killed, Xia Xiaodong and the others extracted a total of more than a dozen related videos from the surrounding surveillance videos, most of which were women with children.

However, since there is a school not far from Ma Qingsheng's community, many other people with children were filtered out from the video.

For the remaining dozens of relevant videos, people in the police station visited nearby residents one after another to find these people.

On the surface, it seems to be gathering witnesses for the case, but secretly Zhang Xuan has begun to focus on investigating the recent travel records of these people, as well as the alibi for other cases.

Since there were too many bases, it didn't take long for Zhang Xuan to investigate the alibi of these ten people.

Most of these people are local residents. Their children attend classes nearby, and they passed by here just to go home.

On the day when Ma Qingsheng had an accident, most of them had alibi. Even the few other cases that did not have alibi at that time had alibi.So the suspicion of a serial killer is self-defeating.

For this matter, Zhang Xuan racked his brains and tried his best, but he couldn't find any new clues. In desperation, he had no choice but to start checking the previous surveillance videos again.

It's not very complicated that Ma Qingsheng will become this area, but the surveillance video layout is quite complete, adding up the front and back, except for the time difference, almost all places in this area are monitored.

Zhang Xuan started his investigation again this time. This time he intercepted all the women with children in the video, whether it was a young girl or an old woman who had no ability to kill.

After enlarging the scope of the search, they gained a lot from this investigation. At least twenty cases were added to the list of suspects at once.

On the other hand, Li Yancheng asked Zhang Xuan to show him the surveillance videos after hearing that Zhang Xuan had begun to investigate the surveillance videos.

Zhang Xuan naturally did not refuse, he immediately compressed all the surveillance videos in his hand into a file package, and then passed it to Li Yancheng who was far away.

The person who received the file was Liao Qun, because only Liao Qun would bring his computer with him every day.

That night, when Li Yancheng returned to the hotel after work, he read these materials from the beginning. After reading this time, he himself was a little fascinated, because he didn't see a single one in these surveillance videos that matched his own. Tested and written suspects.

Li Yancheng is naturally confident in his description of criminal psychology. He absolutely does not believe that his criminal profile will be wrong, but judging from these videos, it is obvious that there is no criminal who fits the profile he gave...

Liao Qun saw that Li Yancheng had finally fast-forwarded through the dozens of hours of surveillance video, and went back to watch it again. He couldn't help being curious. He stepped forward and asked, "What happened?"

Liao Qun was in charge of restoring the portraits of the characters in the previous video, but now that the computer is in the hands of Li Yancheng, he naturally has nothing to do, so he had to move a small stool and sit beside Li Yancheng to watch these videos with him.

"If you're tired, go to bed first, I may take a long time." Although Li Yancheng didn't say anything, his eyes were already a little more serious. He naturally didn't think it was wrong to write the multi-crime test, but Now the facts are wrong, which makes him a little bit concerned.

Could it be that he was wrong?

No, Li Yancheng shook his head, he didn't think he was wrong.

Liao Qun didn't know what Li Yancheng was thinking, but he didn't plan to go to sleep, but spent nearly a night with Li Yancheng watching those surveillance videos countless times.

After seeing him, even Liao Qun, who often stayed up late, couldn't help dozing off, but Li Yancheng himself was still full of energy, and his eyes were fixed on the computer screen in front of him without moving.

Liao Qun couldn't stand it any longer, so he crawled aside and went to sleep, while Li Yancheng checked the surveillance video from the beginning.

These surveillance videos can be said to have surrounded the community for almost a whole day, and no one can miss these surveillance videos and enter the community.

That is to say, unless the other party has been waiting in the community for a day or two, it is impossible for the other party to enter the community, but the former is obviously impossible, even if the murderer has strong endurance and can hide in the community for a day , but the other party has a child with him, it is impossible for the child to hide quietly for a day.

So how did the murderer get in?

Li Yancheng had already found out that the person he profiled did not appear in the surveillance video, so he immediately asked Zhang Xuan for the map of Ma Qingsheng's community. He also checked the layout around the community. It is impossible to stagger these surveillance footage.

But after watching countless surveillance videos and still not finding the person he wanted, Li Yancheng had to start over from the previous profile.

The other party was capable of killing Ma Qingsheng with a single blow, and had the ability to open and close the door after killing Ma Qingsheng. She should be a rather strong woman. He must have a certain amount of strength, otherwise it would be impossible to complete this murder.

And judging from the previous murder cases, there are many places that proved Li Yancheng's conjecture.

Secondly, judging from the height of the other party, the other party can hang Ma Qingsheng's tie on a high nail behind the door, and his height should not be less than 1.6 meters five.

Moreover, when the other party murdered Ma Qingsheng, the angle was almost parallel, not from bottom to top, nor from top to bottom. From the analysis of the wound, the height of the other party should be about five centimeters higher than Ma Qingsheng's. , and Ma Qingsheng himself is already about 1.7 meters.

When an ordinary person stabs at the opponent, if the opponent is about the same height as himself, when the knife penetrates the opponent, in order to facilitate the use of strength when piercing with the hand, the wound is almost parallel to the upward wound.

If the victim is shorter than the murderer, the stab marks will usually be lower, and vice versa.

The knife edge on Ma Qingsheng's neck is almost parallel upwards, so Li Yancheng's 1.7 meters five is absolutely correct, not wrong.

Killing people is an extremely unpleasant thing. Therefore, if a child, a pure and innocent existence, is brought into this case, then it must be to treat the whole murder as a very sacred existence, not murder. But obliterate!

Or, the exact opposite.The main purpose of the murderer doing these things is to threaten or intimidate the child, causing the child to be greatly shocked or traumatized.

The reason for the second guess is that Li Yancheng has not guessed it in detail, because it is untenable. If the other party really hurts the child in the future, then there is no need for him to bring some small bags for the child every time he commits a crime. stuff.

He brought toys and snacks to the child when traveling, which is obviously a sign of pampering the child.

A woman with a full height of 1.7 meters [-], and a powerful woman who dotes on her child but takes her child to kill...

Li Yancheng seemed to have thought of something, suddenly a flash of inspiration flashed in his eyes, he quickly put down the general and then woke up Liao Qun who was sleeping on his stomach next to him, and asked the other party to find something for him to see.

Liao Qun was already about to fall asleep. After being woken up by Li Yancheng, he searched for things in a daze. After finally giving Li Yancheng what Li Yancheng asked for, he never thought that Li Yancheng just took a look and went out.

At first he thought that Li Yancheng had gone to work, but after sleeping for a while in a daze, he realized that Li Yancheng did not bring any camera equipment with him when he left.

But after he fully woke up, Li Yancheng had already disappeared.

Liao Qun called Li Yancheng, but the other party didn't answer.

In desperation, Liao Qunzhi called Zhang Xuan to ask him if Li Yancheng had called, but Zhang Xuan told Liao Qun that Li Yancheng had asked him about the woman's ex-boyfriend before.

After getting the exact address, Liao Qun rushed there inexplicably.

When Liao Qun arrived, Li Yancheng was standing at the gate of a residential area. Seeing Li Yancheng and Liao Qun trotting over to ask him what was going on, Li Yancheng shook his head lightly. He pointed to the gate of the community with his chin, and then said: Not sent.

There is a guard hall at the entrance of the community, and there are guards standing and dedicated to their duties in the guard hall.

This neighborhood is obviously not that kind of ordinary neighborhood. Judging from the outside situation, it's probably a rich area.

Moreover, most of the people who come in and out are well-dressed people, which are somewhat different from other places.

The guards here are not the kind of guards in ordinary communities, they can be soft-spoken, so even if Liao Qun or Li Yancheng wanted to do something, they couldn't get in, so they had to wait outside.

Li Yancheng himself didn't seem to be in a hurry, he just stood at the gate of the community in a daze.

Liao Qunzhi waited beside Li Yancheng, and he didn't know how long it took before Li Yancheng made a sudden movement. He suddenly walked forward and collided with someone.

Liao Qun didn't realize it, but when he did, Li Yancheng had already chatted with the person he bumped into.

Liao Qun stepped forward and heard the young man bumped by Li Yancheng ask Li Yancheng to sit upstairs.

The ice cream was shattered at the feet of these two people.

The weather is not warm now, and there are only a few people who eat ice cream in this weather.

It seems that Li Yancheng rushed out just now, so he knocked all the ice cream in the opponent's hand to the ground and shattered it.

The young man was well dressed, his words revealed a feminine temperament, his facial features were soft, and there was a smile on his face.

"You still eat ice cream in such cold weather, it's really good for your stomach." Li Yancheng said, looking at the ice cream on the ground, Li Yancheng seemed to have lingering fears.

The young man smiled, shook his head and said, "It's not me who wants to eat, but the children in my family who want to eat. I also told him that this kind of ice can't be eaten in this weather, but he just didn't listen."

"You also have children at home? I thought you weren't married yet, and you looked very young." Li Yancheng said, "Where did you buy this ice cream? Otherwise, I'll buy one to compensate you, or the children in the family will make trouble." My temper is bad."

"Hahaha... He's not married yet, so let's forget about ice cream. After all, I didn't want to give it to him, and it's this weather, so what should I do if I have diarrhea?" The young man smiled generously: "But I'm afraid I have to Please accompany me home and tell him that it’s not that I didn’t buy it for him, but that I dropped it halfway, my house is not far from here, would you like to go in and have a seat?”

The other party's words have reached this point, so Li Yancheng is naturally not good at refusing, so he nodded and replied: "Yes, yes, but won't you bother me?"

"It's okay, it's okay..." When the young man heard Li Yancheng agree to the matter, he immediately led Li Yancheng into the community with a smile on his face. With the young man leading the way, the security guards in the community did not stop him, so the three of them quickly went upstairs.

"I don't think you are locals, why are you here?" asked the young man walking in front.

Before Liao Qun could speak, Li Yancheng answered, "My cousin and I came here to look for a job. My cousin introduced us to a place to try. I happened to go to work today, and I met you at the door on the way. .”

Liao Qun walked last, his eyebrows twitched fiercely after hearing Li Yancheng's words, cousin?Cousin?

Li Yancheng doesn't look old in appearance, he pretends to be a student who has just graduated, and Liao Qun himself is the same, but after listening to Li Yancheng's words, Liao Qun gave birth to someone for the first time, maybe he should cut off his hair idea.

The young man didn't know what was going on, he didn't take them to the elevator, but took them to the green passage, and both of them were panting all the way to the fifth floor.

When he arrived at the door, the young man directly opened the door and made a welcome gesture to the two of them, "Sit whatever you want, I'll pour water for you to drink, you're tired from walking the stairs, I rarely use elevators because of exercise."

After entering the door, the young man went to the side to pour water, and a little boy who was almost six years old ran out. He seemed to be startled when he saw Li Yancheng and Liao Qun inside the room, and asked to show a weird smile , Then turned around and ran back to the room.

The child's movement of pulling the corners of his mouth was very weird, it seemed to be small, but it didn't seem to be smiling, and it was more like a sneer.

Liao Qun was taken aback, he shuddered and moved to Li Yancheng's side, and asked in a low voice, "This kid is really scary."

At this time, the young man had already come out with three glasses of water. Seeing that the two were still standing, he immediately took care of them and said, "You are welcome, sit down. This is lemonade. You just have to drink some. I will go and see." Look at that fussy little guy."

After the man left, Liao Qun immediately went to bring water, he drank two gulps, he ran very fast to catch up with Li Yancheng before, and now he was already thirsty after climbing five floors of stairs.

"Do you want more?" Li Yancheng asked.

Seeing this, Liao Qun nodded quickly. He took Li Yancheng's cup and drank it in a big gulp. His own cup was already empty.

When Liao Qun finished his second glass of water, the man came back to the living room with the child in his arms, "Do you want more water?"

Li Yancheng shook his head, Liao Qun was already full after drinking two large glasses of water, so he also refused.

"I accidentally broke your ice cream just now, so I came up here to apologize to you. Now that I'm done apologizing, we should leave." Li Yancheng stood up and smiled at the child with a smile, and then Just get ready to go.

The child also smiled when he saw this, and it was at this time that Liancheng realized that the other party seemed to have reached the age of tooth replacement, so the teeth in his mouth were somewhat vacant.

He seemed shy, wanting to laugh but not daring to laugh.

Li Yancheng walked towards the door, but when he reached the door, he found that the door was locked and could not be opened.

Li Yancheng looked back suspiciously, only to see that young man was still standing in the living room with the child in his arms, and Liao Qun didn't follow him for some reason, but sat on the sofa and held his forehead, as if he felt a little uncomfortable.

"Liao Qun?" Li Yancheng took two steps back and called Liao Qun's name.

Liao Qun, who was already dizzy, heard Li Yancheng's voice in his dizziness. He looked up at Li Yancheng, but because his vision was already blurred, all he saw was a blurry figure.

"Li Yancheng...be careful..." Before he finished speaking, Liao Qun's neck tilted and he passed out from sleep.

"What do you want?" Li Yancheng asked warily.

"Go and play while Daddy is very busy." The young man still had a smile on his face, he put the child down in his arms, and then he looked at Li Yancheng: "I know you are a policeman, you don't have to keep pretending. "

Li Yancheng remained unmoved and stood still.

He looked at Liao Qun and then at the young man, as if he was calculating the distance between the two and how to rescue Liao Qun successfully.

"Since you're here, don't even think about leaving." The young man went to the side cabinet and opened it, and took out a knife from the cabinet, "I knew something was wrong when Hongzhen called before. I thought you came here so quickly."

"Since you already know that we are the police, you should quickly arrest us without making any further mistakes. If you let us go, we will talk to our superiors, and we can be punished lightly." Li Yancheng walked in the direction of Liao Qun, then The young man didn't stop Li Yancheng either, but let him walk to the side of the sofa.

"Let's go? Do you think you can still go?" The young man smiled. "Do you think you are the first policeman to come here?"

Li Yancheng stared slightly, as if he had heard something incredible.

But the young man laughed again: "And when you came in with me, there was no monitoring other than the guards downstairs. That is to say, if you disappeared by then, they would have no evidence to implicate me."

The young man's words were somewhat contradictory, but Li Yancheng understood the hidden meaning.

I'm afraid that the guard was also arranged by this person. Although I don't know how the other party found them, but from the current point of view, I am afraid that all this is a situation he has set up long ago.

Just waiting for someone to notice and jump down.

No matter who discovered this matter in the end, and who came to him, they could not escape this disaster.

The young man looked at Li Yancheng, he was patiently waiting for Li Yancheng to start dizzy...

Playing with the knife in his hand, he took it easy and seemed to be very confident in the game he had set up.
