of the main text volume, Wang Fenglei, who lives, leaned on the chair and breathed a deep breath.

15 years ago, Wang Fenglei was just 40 years old, and Nian R&F was at the peak of his career aspirations.

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

But the murderer of this serial murder gave Wang Fenglei a wake-up call.

When the murderer committed the first crime, Wang Fenglei was the captain of the grassroots investigation team at that time.

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

It was not until later that Wang Fenglei became the deputy captain of the Shenshi Investigation and Case handling that he directly led the case handling.

It can be said that from the first case to the fourth murder ten years ago, Wang Fenglei gradually became an ordinary case-handling participant and the final direct person in charge.

In Wang Fenglei's heart, the pressure and obsession caused by this serial murder case is difficult for outsiders to understand.

Now, after ten years, Wang Fenglei finally saw hope of solving the case.

"Chen Yan, thank you!"

Turning around, Wang Fenglei sincerely thanked Chen Yan.

"Battle Wang, you are polite. This is what I should do. Besides, the case has not been solved yet, don't rush to thank me."

Chen Yan is in a relatively relaxed mood now.

Serial murder cases are different from general murder cases.

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

Often, the one who falls into the detective's sight at the first time is not necessarily the final suspect.

Sometimes, it often feels that there is no possibility of crime, but it is the murderer in the end, such as Liu Zhi in the last case.

Who would have thought that the victim's childhood friend would be the ultimate murderer?

Compared with the case that Chen Yan handled before, the turn may be less, but the other party was hiding more deeply.

This is a game of hide and seek.

The next time is not a hurry, everyone is waiting.

Wait for the video of Liu Qingshan and his group to check the situation, and wait for Zhang Chaoyang to investigate the situation in the Beijiao Ceramics Factory.

This wait took three hours.

At 7 pm, Zhang Chaoyang returned first: "There is news in the northern suburbs!"

oh?

Chen Yan straightened his back: "Tell me quickly."

"The ceramic factory recruited more than 20 temporary laborers the day before yesterday and carried a batch of red clay."

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

"They recruited people in the labor market of the self-built house area of ​​Phoenix Street. After the work is done, no one knows 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 in the ceramic factory?"

"There are monitoring equipment, but the place where they helped transport red clay was in a factory behind the ceramic factory, which was a surveillance blind spot."

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

Have you found it?

“Have you brought the video back?”

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

While saying that Zhang Chaoyang linked the computer and the projector: "But it's a pity that the camera at the entrance of the ceramic factory was not high-definition, and there were many people at that time, so the shooting situation was not ideal."

While speaking, the surveillance video of the ceramic factory at 9:30 a.m. the day before the incident began to be played.

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

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

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

As the video was played, a group of people came around in a vast way.

In the slightly blurry video, I can't see the appearance of the pedestrians clearly. A group of people walked by, only five seconds.

"Put it backwards!"

Others can't see clearly, but Chen Yan still finds some discoveries.

Chen Yan, who has turned on the visual gene lock, has just locked on everyone's morphological movements.

Play back again and confirm again.

Liu Qingshan nodded. He had seen this scene four or five times, but he had not found anything.

"stop!"

Liu Qingshan pressed the mouse and the time just stuck at 9:31:08.

"Enlarge it, this person is right!"

In the enlarged picture, Chen Yan pointed at one of the men wearing blue labor protection uniforms, and became more and more excited as he looked.

"Battle Wang, it's him!"

This person?

Wang Fenglei definitely does not have Chen Yan's perverted vision. The people in the picture, because the pictures are relatively blurry, are almost the same in his opinion.

"Team Leader Chen, are you sure?"

"It should be no problem. This person's left foot is too heavy when walking, and it is a bit inconsistent with others."

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

But unfortunately, although the texture of the pictures on the computer is better and the colors are brighter, everyone's faces are still blurry and they can't see clearly at all.

"Can we restore human faces through technical means?"

This question is not required for technicians to answer, but Chen Yan from the computer program can answer: "This can obtain some clearer pictures by eliminating the influence of noise and other means."

"However, this kind of recovery is limited, and it is impossible to get very clear high-definition images. On the other hand, you see, when this person walks into the door, the angle of the camera is related to his back-to-face."

"Most of these people just showed their side faces. The facial information exposed by this person is better, with only the left ear and a small part of the cheek."

"Chaoyang, is there any surveillance videos they came out?"

If it's a video, it's easy to do. In this way, everyone will face the camera and be able to take a picture of the face.

In that case, it is very likely that a more valuable portrait of the criminal suspect will be obtained after the screen is restored.

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

The clues from the ceramic factory were broken.

However, this clue is still very valuable. Although the suspect cannot be directly found through this clue, the clue verifies all the judgments of Chen Yan and Wang Fenglei of the suspect before.

In particular, it is very important to verify the results of Chen Yan’s footprint analysis.

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

Most of the murderers in serial murder cases have the same characteristics.

That is confidence in yourself.

He firmly believes that he will not be caught in his crime, otherwise he will not commit crimes continuously.

Therefore, it is relatively unlikely that this person will escape from Shenzhou after the incident.

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

According to the information provided by the person in charge of the ceramic factory recruitment, he recruited this group of people in the labor market of the self-built house area.

Then, even if there are no clues found on Liu Qingshan, Chen Yan and the others can wait for the labor market.

It's still easy to find a cripple.

While Chen Yan was trying his best, the video screening work on Liu Qingshan was also in full swing.

More than 300 people were in one venue and had been in the middle of seven hours.

Everyone's eyes are red now, just like rabbits.

The sound of mouse clicking is in the entire venue.

In the video screening, more than ten hours are the ideal state.

It is theoretical calculation time, but when viewing it, it needs to be repeated and confirmed, so the video will be played back and forth continuously.
