Chapter 535 Habitat (Please Vote for This Big Chapter!)

Wang Fenglei sat back on the chair and took a deep breath.

15 years ago, Wang Fenglei was just 40 years old, and he was at the peak of his career ambitions.

With a certain position and a certain amount of experience, I have just reached the best age to show my ambitions.

But the murderer of this serial murder case gave Wang Fenglei a slap in the face.

When the murderer first committed the crime, Wang Fenglei was the captain of the grassroots detective team.

Wang Fenglei was not directly responsible for the case at that time, but cooperated with the handling of the case.

It was not until later that Wang Fenglei became the deputy captain in charge of criminal investigation in Shen City that he directly led the investigation.

It can be said that from the time the murderer committed the first case to the fourth murder ten years ago, Wang Fenglei gradually changed from an ordinary participant in handling the case to the final person directly responsible.

This serial murder case created pressure and obsession in Wang Fenglei's heart that is difficult for outsiders to understand.

And now, after ten years, Wang Fenglei finally sees hope of solving the case.

"Chen Yan, thank you!"

Turning around, Wang Fenglei sincerely thanked Chen Yan.

"Team Wang, you are so polite. This is what I should do. Besides, the case has not been solved yet, so don't be in a hurry to thank me."

Chen Yan is now in a more relaxed mood.

Serial murder cases are different from ordinary homicide cases.

Many of the cases Chen Yan had handled before were confusing.

Often the person who falls into the detective's sight first is not necessarily the final suspect.

And sometimes, it often feels like there is no possibility of committing a crime, but in the end it is the murderer, such as Liu Zhi in the last case.

Who would have thought that the victim's childhood was the ultimate murderer.

Compared with Chen Yan's previous cases, this case may have fewer twists and turns, but the other party is hiding deeper.

This is a game of hide and seek.

It is not the time to be anxious next time, everyone is waiting.

Waiting for the video review of Liu Qingshan's group, and waiting for Zhang Chaoyang's investigation at the Beijiao Ceramics Factory.

This wait is three hours.

At 7 o'clock in the afternoon, Zhang Chaoyang was the first to return: "Team Wang, Team Chen, there is news from the northern suburbs!"

oh?

Chen Yan straightened his back and said, "Tell me quickly."

"The ceramics factory hired more than twenty temporary workers the day before yesterday to transport a batch of red clay."

"According to the recollection of the person in charge at the time, there was indeed a lame middle-aged man working, but he didn't know his specific name."

"They recruited people from the labor market in the self-built housing area on Fenghuang Street. They paid them on the spot after the work was done, and no one knew anyone."

Labor market?

The information brought back by Zhang Chaoyang further verified Chen Yan's judgment.

The murderer lives in the Phoenix Street area.

"Is there any surveillance at the ceramics factory?"

"There is monitoring equipment, but the place where they help transport the red clay is in a factory building behind the ceramics factory. That place is a blind spot for monitoring."

"However, these people all passed by the gate when they entered the factory, and we discovered a little bit."

Any discovery?

"Did you bring the video back?"

Zhang Chaoyang nodded: "I have copied the video back. I also investigated the basic situation at the scene. The temporary workers entered the factory around 9:30 the day before yesterday."

While talking, Zhang Chaoyang connected the computer and projector: "It's just a pity that the camera at the entrance of the ceramics factory is not high-definition. There were many people at that time, so the shooting situation was not ideal."

While they were talking, the surveillance video from the ceramics factory at 9:30 a.m. the day before the incident began to play on the projector.

As Zhang Chaoyang said, the quality of the surveillance video is average and the clarity is not good enough.

Moreover, this camera has a fixed angle and cannot track the camera.

The time displayed in the upper left corner is exactly 9:30.

The video is playing and a group of people are approaching.

In the slightly blurry video, the faces of the pedestrians could not be seen clearly. A group of people passed by for only five seconds.

"Play it backwards!"

Others couldn't see clearly, but Chen Yan still made some discoveries.

Chen Yan, who has opened the visual gene lock, has just locked everyone's form and movement.

Play it back again to confirm again.

Liu Qingshan nodded. He had seen this scene four or five times, but he still found nothing.

"stop!"

Liu Qingshan clicked the mouse, and the time happened to be stuck at 9:31:08.

"Zoom in a little more, this person...yes, that's him!"

In the enlarged picture, Chen Yan pointed at one of the men wearing a blue labor insurance suit, and the more he looked at it, the more excited he became.

"Team Wang, that's him!"

this person?

Wang Fenglei definitely didn't have Chen Yan's abnormal eyesight. The people in the picture looked similar to him because the picture was blurry.

"Team Leader Chen, are you sure?"

"It should be fine. This person's left foot undulates too much when he walks, which makes him a little uncoordinated compared to others."

Wang Fenglei got up and came to the computer. Compared with the projection, the computer's clarity should be better.

But it's a pity that although the quality of the picture on the computer is better and the colors are brighter, everyone's faces are still blurry and cannot be seen clearly at all.

“Can human faces be restored through technical means?”

This question does not need to be answered by a technician. Chen Yan, who is proficient in computer programs, can answer: "This can be achieved by eliminating noise and other means to get clearer pictures."

"However, this kind of restoration is limited, and it is impossible to obtain a very clear high-definition picture. On the other hand, you see, when this person walked into the door, the angle of the camera was facing away from him."

"Most of these people only show the side of their faces. This person's facial information is better, only the left ear and a small part of the cheek."

"Chaoyang, is there any surveillance video of them coming out?"

It would be easier if the video came out. In this case, everyone would be facing the camera and their faces could be photographed.

In that case, it is very possible to obtain a more valuable portrait of the criminal suspect through screen restoration.

However, Zhang Chaoyang shook his head: "After these people moved the red clay, they all left in the back door in a clay cart, and there was no surveillance camera at the back door."

The clue to the ceramics factory...is broken.

But this clue is still very valuable. Although the suspect cannot be found directly through this clue, the clue has verified all the previous judgments of Chen Yan and Wang Fenglei about the suspect.

In particular, it is very important to verify the results of statement footprint analysis.

Although the suspect's face cannot be seen clearly in the video, the suspect's height, body shape, lameness, etc. are all obvious.

Most serial killers have the same characteristics.

That is confidence in yourself.

He firmly believes that he will not be caught committing crimes, otherwise, he will not commit crimes continuously.

Therefore, the possibility of this person escaping and leaving Shen City after the incident is relatively small.

In other words, the suspect is most likely still living in the self-built house on Phoenix Street.

According to the information provided by the person in charge of recruiting workers at the ceramics factory, he recruited these people in the labor market in the self-built housing area.

Then, even if Liu Qingshan found no clues, Chen Yan and the others could wait and wait in the labor market.

A lame man is still easy to find.

While Chen Yan was trying every possible means, the video screening work on Liu Qingshan's side was also in full swing.

More than 300 people stayed in one venue for more than seven hours.

Everyone's eyes are red now, like rabbits.

The entire venue was filled with the sound of mouse clicks.

For video screening, more than ten hours is the ideal time.

This is a theoretical calculation time, but when you actually watch it, you need to confirm it back and forth, so the video will be played back continuously.

Therefore, even after such a long time, the work is only half done.

Liu Qingshan divided more than 300 people into more than 30 groups.

Work in groups of ten, with each group assigned work according to blocks, so that the final summary can be facilitated.

And once a group discovers the situation, the surveillance videos screened by the surrounding groups are the closest to the specific situation group's video location, so the problem can be discovered continuously!

"Report! There is a situation in Group 32!"

Suddenly, a report interrupted the intensive sound of mouse clicks in the venue.

Liu Qingshan immediately stood up and swayed, looking in the direction of the report.

Nearly eight hours have passed, 36 teams of detectives, more than 360 people, this is the first team to make a discovery.

There was no need for the team members to come over to report, Liu Qingshan had already trotted over.

"Is this the case?"

"taxi!"

The leader of Detective Group 32 is a middle-aged man who also participated in the investigation of serial cases back then.

Now that clues have been found in the surveillance, he is even more excited than Liu Qingshan.

"Team Liu, we found Li Yansong's taxi!"

"Let me see!"

On the computer screen is the paused surveillance video image.

This is a surveillance camera installed by a supermarket itself. It is located at the door. The camera is facing the supermarket door.

However, because the inner streets of Phoenix Street are relatively narrow, part of the video range of this camera includes half of the street.

At this moment, what appeared in the black and white screen was a taxi.

Although it was early in the morning and the surrounding area was dark, the license plate number was still clearly visible due to the light from street lights and billboards.

Liao AT4324!

It was the taxi driven by Li Yansong!

"If you turn it upside down, can you clearly see the people sitting in the car?"

The middle-aged detective slid the mouse and played it backwards for 3 seconds, which happened to be the moment when the taxi entered the camera recording range.

The main driver was Li Yansong. The lights flickered and he could see clearly.

But, unfortunately, there was no one on the co-pilot.

Play the video, the taxi passes quickly, and there is a figure in the back seat!

murderer!

It must be the murderer!

It's a pity that I can't see the face clearly.

"Report! There is a situation in Group 29!"

"Report! There is a situation in Group 34!"

Just after Liu Qingshan checked the 32 groups of discovered videos, another two groups of detectives made new discoveries.

"map!"

After a lag of more than ten minutes, groups discovered new situations one after another.

All groups begin reporting.

The earliest time is 3:35.

That is, 32 sets of surveillance videos were discovered.

This supermarket is located near the second alley entrance between cameras 36 and 37 on Fenghuang Street.

According to the camera at No. 36 Fenghuang Street, Li Yansong’s taxi passed by the camera at No. 36 Fenghuang Street at 3:30 yesterday morning and then disappeared.

It now appears that Li Yansong turned into the self-built housing area from the second alleyway entrance between the two cameras on Phoenix Street.

On the map, Liu Qingshan marked the first monitoring point and time.

After that comes the second point and time.

At 3:38, at the door of Lao Wang Shaojiu.

3:44, at the entrance of Qingquan Bathing.

At 3:48, at the door of Jiangnan Xiaochao!

There are four points and four time periods in total.

Liu Qingshan marked the four points on the map one by one, and then drew a video of the taxi driving.

Although Li Yansong only appeared at four points in the self-built housing area on Fenghuang Street, he has already spanned the east-west direction of the entire area.

After leaving Jiangnan Xiaochao, there is the Linhe Road opposite.

This access road is still an internal road in the self-built housing area. The entire road is very narrow and can only accommodate one vehicle.

And the road is unpaved, so naturally there are no cameras on this road.

"The north side of the sidewalk is a dead end, and the other party can only drive south..."

Liu Qingshan followed the map and analyzed it carefully.

From Jiangnan Xiaochao to the end of the south side of the sidewalk, it is 3 kilometers in total.

"Is anyone familiar with this trail?"

"I am familiar with!"

A detective stepped forward: "My family used to be here. I grew up by this river."

It turns out that this sidewalk was created by nearby residents who trampled on it for a long time to transport supplies.

"Most people don't know about this sidewalk. Only people who live here know about it. Moreover, this road is close to the river and there are many mosquitoes. At night, there is no one at all."

"There were a few robberies in the past few years, but gradually, fewer people left here at night."

"Which way to go from here to the cement factory?"

"Go straight along the river. After six kilometers, turn left and you will reach the cement factory."

"Let's go to the scene!"

Half an hour later, Liu Qingshan followed the sidewalk along the river and arrived directly at the cement factory where the crime occurred.

Along the way, let alone cameras, there were no people.

At this point, Li Yansong's driving route that night was finally determined.

Buzz!

Liu Qingshan was just about to return when the phone rang. It was the temporary person in charge of the monitoring team calling: "Team Liu, we have made a big discovery!"

An hour later, all the video materials were placed in front of Chen Yan and Wang Fenglei.

Liu Qingshan is making a report.

"Li Yansong turned into the self-built housing area of ​​Fenghuang Street at the second alley at 3:35 yesterday, and then..."

The entire driving trajectory of Li Yansong's taxi was clearly checked.

"We initially suspect that the murderer used ether to stun the driver on the sidewalk along the river, then drove to the cement factory, and then committed the murder."

"And on top of that, we found this!"

On the projection, there is a screenshot of a video.

"Yesterday at 3:25 in the morning, there was a drug store at the entrance of the first alley just past the camera at No. 36 Phoenix Street. The drug store's surveillance camera captured this!"

In the screenshot, there is a thin man, about 1.7 meters tall, wearing a blue labor insurance suit.

"Team Wang, Team Chen, please watch the video of that time."

Click the mouse and the video plays.

At 3:23, a figure appeared on foot within the monitoring range of the pharmacy.

Because of the angle, I can't see his face clearly, but I can see that the other person is wearing a mask and a cap.

He walked slowly, his body undulated slightly while walking, and his left foot was obviously lame.

Wang Fenglei's eyes were like hawks, staring at the thin man in the video.

"is it him?"

Liu Qingshan nodded: "We compared the figures in the taxi. Although we couldn't see their faces clearly, their clothes were very similar."

"In addition, this person is lame on his left foot, there is a high probability that it is him!"

Speaking of which, there was some luck in finding this person.

Li Yansong's taxi passed the camera at No. 36 Fenghuang Street at 3:30.

Li Yansong was the only one in the car at that time, so the murderer must have got into Li Yansong's taxi after 3:30.

In order to save time, Liu Qingshan requires all detectives who investigate video materials to start after 3:30.

But all detectives copied the complete video data.

The group that discovered the man completed the work relatively quickly and completed the video review before Liu Qingshan checked the sidewalk along the river.

When I had nothing to do, I just watched videos from previous time periods.

As a result, at 3:25, this video was discovered.

"Can you confirm the identity of the other party?"

"This is a bit difficult. Although the surveillance camera captured him, it did not capture his face. However, we have roughly determined the area where the suspect lives."

After Liu Qingshan discovered the surveillance video of this man, he asked everyone to check the surveillance video and quickly marked the person's movement track.

A high-definition satellite map of the Phoenix Street self-built housing area appears on the projection.

"This person first appeared on the surveillance camera at 2:58, and that was the initial location."

On the projection, it is a small supermarket.

"We checked all the private surveillance cameras near this supermarket and found no such person, so we can probably delineate the area where the other person lives."

On the projection, all surveillance cameras near the small supermarket have been marked.

Since only the camera of the small supermarket captured the suspect, but no other cameras captured it, it means that the other party can only appear first from this area.

There are three self-built houses in this area.

"Anyone coming out of any of these three self-built houses may be caught by the camera of the small supermarket."

Three buildings!

This is where the other party lives!
