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 graphic investigation detachment, this temporary transfer was not ordinary at this time, Xu Zheng was not arranged to the conference room this time, but arranged to a small conference room with more than 20 Changming City camera video analysis experts, and a huge display screen group was hung on the front wall of the conference room.

It seems that Xu Zhengneng was transferred because of his ability to analyze videos.

Before he officially worked, he asked this group of people to sign a confidentiality agreement, Xu Zheng took a look, the level is not high, so it seems that this time the eucalyptus is not as important as the accidental murder.

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

The job content is very simple, that is, to analyze the video collected by the colleagues of the technical investigation, find suspicious people at a fixed time period, and write the reason.

Xu Zheng didn't know until the task was assigned to him that the death eucalyptus of the security guard was really one of the series of eucalyptus.

There are three groups of tasks, each group corresponds to a death eucalyptus, Xu Zheng's task is indeed simple, that is, to watch the camera footage of the eucalyptus place one hour before and after the death time of these three people, and find suspicious people.

Then it's not easy.

Xu Zheng first watched how big the video of each group was, and the result was less than half of the usual eucalyptus scene, and he guessed that first, because it was night, and second, the time of occurrence of the three eucalyptus was all rainy days, so there were not so many tachographs on private cars.

What was given to Xu Zheng above was a USB flash drive, no text description, no introduction, just let everyone watch the video and find out who might be a suspect by feeling.

To be honest, Xu Zheng felt speechless, it was obvious that the criminal police detachment did not find any suspicious characters, and could only think about whether clues could be found in the video video.

Xu Zheng picked up the security guard's eucalyptus and prepared to take a look at it first, after all, he was a little familiar with this eucalyptus.

According to the forensic examination, the time of this eucalyptus was about 3:30 in the morning, and Xu Zheng needed to see the time period before and after one hour each.

And because the two cameras at the entrance of the community are broken, the only cameras collected by the Physical Evidence Department are the road cameras within a radius of 2 miles from the community, and the tachographs on 26 cars during this period of time.

There are a total of 53 cameras, Xu Zheng watched 9 cameras at the same time, and at 6 times the speed, he watched this set of videos in more than 2 hours.

But he didn't find any suspicious people, there were only 6 passers-by at this point in the radius of 2, half of them were drunk people, walking staggeringly, Xu Zheng marked them.

Then look at the second set of videos, the place where this eucalyptus occurred is located in Nanjiang District, Lao Street, a street that has been closed due to government projects, there are no street lights, the eucalyptus occurred at more than 3 o'clock in the morning 3 days ago, and the eucalyptus occurred at the corner of a hidden two shops on the side of the road.

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

Basically, it took about 1 hour to read it, Xu Zheng marked 3 people, the main thing is that there are fewer cameras available for this eucalyptus, and when the street goes out at night, there are a lot fewer cameras, and it is still on a rainy night...

The third set of videos, more, eucalyptus occurred in a small open park in Xuangui District, the eucalyptus time was 10 days ago on a rainy night, the specific eucalyptus time is unknown, but the time of death of the deceased was about one o'clock in the morning, the place of death was under a crooked neck tree in the park, the specific cause of death list is not specified, the deceased is a middle-aged man in his 40s, is a poacher who secretly came to the small river in the park.

This time the above to collect more cameras, although it is a rainy night, but only about 1 o'clock in the morning, there are a lot of vehicles on the road, more than 1 o'clock in the morning, there are a few people in the small park, Xu Zheng found 8 teams of men and women at several entrances to the park, the camera on the rainy night can only see their model lake figure, but it doesn't matter, there are several teams are driving cars separately, Xu Zheng marked their cars down.

The remaining teams found through cameras along the street that the men and women were basically separated and walked into different neighborhoods.

You don't have to guess, you know that these are wild mandarin ducks, the rainy night 10 days ago was already drizzling at one o'clock in the morning, under the big trees, under the pavilions, in the corridors, and even in the park toilets...

Indeed, the field war is more cost-effective than the hotel, and there is no open record, but this time it is fate, I don't know if this time will destroy their family.

In addition to these people, there are also some lone passers-by who got into the small bamboo forest in the park, more than 20 minutes, Xu Zheng also marked down, there are 7, and the cameras at the roadside intersection can probably see their appearances.

Xu Zheng guessed that Zhuang Qiang hadn't rested well for so long, and it was likely that he had investigated these wild mandarin ducks and these 7 single passers-by.

At the end of the day, Xu Zheng looked at these cameras four or five times, and in the end, he even doubted everyone he saw on the video, because he didn't find any exact suspicious person, and it was estimated that the gang of people in the criminal police detachment also sent people to analyze the video.

Therefore, Xu Zheng turned off the video and fell into contemplation, one is the security room at the entrance of the community, the other is under the big tree in the park, and the other is in the shadow of the street, the common point is that it is a rainy night, early in the morning, there are few pedestrians, and the way of death is related to hanging, and the deceased should have no relevance.

These are combined, Xu Zheng suddenly has a feeling, this is very similar to the police academy learned to kill for the sake of excitement, but if so, the murderer will be even more difficult to find, because he is a normal person when he is normal, and only on rainy nights will he show his crazy side.

But this is just speculation, it is a profile, Xu Zheng is not sure, this is just his own crankiness, mainly because there is too little information at hand, and he doesn't even know how the deceased died.

Look at the three places of death, the bridge area, the ** area, and the turtle area, spanning three districts, and these three districts are not connected, if this is a person to make eucalyptus, the span is too big, as if he goes wherever it rains, he will come out to make eucalyptus.

Xu Zheng recalled that the only community he had been to in the 10,000-person village had found no suspicious people in the cameras collected outside the community, so what if he had entered the community a day ago or two in advance to hide, or he himself was the owner of the community.

Hey, this must be a good idea, but then Xu Zheng was discouraged, he could think of it, and it was estimated that the people of the heavy team would also think of it, but why didn't they provide them with a video of entering the community in the past three days?

"The Legend of the Fairy Tree"

No matter what, Xu Zheng summarized the video, sorted out the people he marked for the first time, and wrote the reason for suspicion, but in fact, it was not a reason, there was really no reason to think about it, Xu Zheng wrote "by feeling".

He also wrote his suspicion that the murderer might have infiltrated the community in advance under the report, maybe this article can add points to himself.

After getting off work at 7 o'clock in the evening, colleagues from the graphic reconnaissance detachment came to collect the information, and Xu took the opportunity to take a look at the information when he was handing over the information.
