I don't want to solve the case when I'm a little policeman.

Chapter 93 Deployment of the Picture Investigation Detachment

The next day, as soon as Xu Zheng arrived at the police station, he was called to the city bureau by a phone call from the Map Investigation Detachment. This temporary assignment was unusual at this time. City camera video analysis experts arranged to a small conference room, a huge display group hung on the front wall of the conference room.

It seems that Xu Zhengneng was sent here because of his video analysis ability.

Before they officially started working, they asked this group of people to sign a non-disclosure agreement. Xu Zheng took a look and saw that the level was not high, so it seemed that this case was not as important as the accidental murder case.

Soon, as the task was issued, Xu Zheng and the others began to work.

The job content is very simple. It is to analyze the video collected by the inspection team, find suspicious persons in a certain fixed time period, and write down the reasons.

Xu Zheng didn't know until the task was assigned to him that the death of Mr. Security was really one of a series of cases.

There are three groups for the task, each group corresponds to a death case. Xu Zheng and his team's task is really simple, that is, to review all the camera recordings of the crime scene one hour before and after the time of the three people's death, and find the suspicious persons.

Then it's not easy.

Xu Zheng first looked at the size of each group of videos, and the result was less than half of the usual crime scene. He guessed that one was because it was night, and the other was that the three cases happened on rainy days, so there were not so many private cars. on the driving recorder.

What was given to Xu Zheng above was just a USB flash drive. There was no written description and no introduction to the case. It was just for everyone to watch the video and find out who might be the suspect by feeling.

To be honest, Xu Zheng felt very speechless. It was obvious that the criminal police detachment did not find any suspicious persons, so he could only think about whether he could find clues in the video.

Xu Zheng picked up Mr. Security's case and prepared to look at it first, after all he was a little familiar with this case.

According to the forensic identification, the time of this case happened around 3:[-] in the morning, and Xu Zheng only needed to look at the one hour before and after this time period.

And because the two cameras at the entrance of the community were broken, the only cameras collected by the visual inspection were the road cameras within a radius of 2 miles of the community, and the driving recorders on the 26 cars during this period of time.

There are only 53 cameras in total, and Xu Zheng watched 9 cameras at the same time. According to the 6x speed, he finished watching this group of videos in more than 2 hours.

But he didn't find any suspicious people. There were only 2 passers-by at this time within a radius of 6, and half of them were drunk people walking shakyly. Xu Zheng marked them down.

Then watch the second set of videos. The incident took place in Nanjiang District, an old street, a street that was closed due to a government project, and there were no street lights. There is a hidden corner of two shops on the side of the road.

The way of death was even more bizarre, the young girl was hanged here, the specific cause of death was not mentioned in the task list.

Basically, it took more than an hour to finish watching. Xu Zheng marked 1 people. The main reason is that there are fewer cameras available for this case. When the power goes out at night on this street, there are many fewer cameras, and it is still a rainy night.
The third group of videos has more videos. The case happened in a small open park in Xuangui District. The time of the case occurred on a rainy night 10 days ago. It was under a tree with a crooked neck in the park. The specific cause of death was not specified in the list. The deceased was a middle-aged man in his 40s, who secretly came to the park to fish by the small river.

This time, the cameras provided above collected more cameras. Although it was a rainy night, it was only around 1 am. There were a lot of vehicles on the road. After 1 am, there were also a few people active in the small park. Xu Zheng found it at several entrances of the park. There were 8 teams of men and women, and the camera on a rainy night could only see their blurred figures, but it didn't matter, some teams drove away separately, and Xu Zheng marked down their cars.

The remaining teams found that men and women basically walked into different communities separately through cameras along the street.

No need to guess, you know that these are wild mandarin ducks. The rainy night 10 days ago was already drizzle at one o'clock in the morning, under big trees, under pavilions, in corridors, and even in park toilets.
Indeed, field battles are cheaper than hotels, and the records have not been released yet. However, this is a murder case. I don’t know if handling this case will destroy their family.

In addition to these people, there were also some single passers-by who got into the small bamboo forest in the park. After more than 20 minutes, Xu Zheng also marked them down. There were 7 of them. The cameras at the roadside intersections could probably see their faces clearly.

Xu Zheng guessed that since Zhuang Qiang hadn't had a good rest for so long, there was a high probability that he had checked these wild mandarin ducks and these seven single passers-by.

At the end of the day, Xu Zheng watched these cameras four or five times. In the end, he even doubted everyone he saw on the video, because he didn't find a single suspicious person. It is estimated that the gang of criminal police detachment were also in the same situation. Only then did someone analyze the video.

Therefore, Xu Zheng turned off the video and fell into deep thought. One is the security room at the gate of the community, the other is under the big tree in the park, and the other is the shadow of the street. The common points are rainy nights, early morning, few pedestrians, and the way of death is peaceful. Hanging is related, and the deceased should not be related.

The combination of these, Xu Zheng suddenly had a feeling that this is very similar to killing people for the sake of excitement, which he learned in the police academy, but if this is the case, it will be even more difficult to find the murderer, because he is a normal person when he is normal, Rainy night will also reveal his crazy side.

But this was just a guess, a profiling, Xu Zheng was not sure, it was just his own wild thinking, mainly because there was too little information at hand, he didn't even know how the deceased died.

Looking at the three places of death, Yiqiao District, ** District, and Xuangui District spanned three districts, and these three districts were not connected. If this case was done by one person, the span would be too large It seems that wherever he goes, it rains and he comes out to commit crimes.

Xu Zheng recalled the only community he had ever been to, Ten Thousand Village, and the cameras collected outside the community did not find any suspicious persons, so if he had entered the community a day or two earlier to hide, or he himself was the owner of the community .

Hey, this must be a good idea, but then Xu Zheng became discouraged. He could think of it, and probably the people in the serious crime team would think of it too, but why didn't they provide them with the video of entering the community in the past three days?
No matter, Xu Zheng summed up the video, sorted out the people he marked for the first time, and wrote down the reason for doubt. In fact, there is no reason, there is really no reason to think about it, so Xu Zheng wrote "by feeling".

He also wrote down his suspicion that the murderer might have sneaked into the community in advance under the report, maybe this one can give him extra points.

After get off work at 7 o'clock in the evening, the colleagues from the Map Investigation Detachment came to collect the materials, Xu Zheng took the opportunity to take a look at the materials, hey, everyone gave the same reasons for suspecting the target as he did.
