Chapter 570： disappearing murderer

.2ksk.

Chen Yan didn't know if the murderer would be invisible, but he was sure that Wang Luyao must have been in the living room before he died.

"Send the body back for inspection first, and wait for the inspection results to come out."

"Yes!"

After the body was sent for examination, Chen Yan went directly to the monitoring room of the community.

Although Zhang Yaoming and others reviewed the surveillance video, Chen Yan believed that there might still be omissions.

The community where Wang Luyao lives is a new community with a very complete video surveillance system.

When he first entered the community, Chen Yan roughly observed the video surveillance layout of the community, and there were basically no dead spots.

In the building where Wang Luyao lives, there are surveillance cameras in the elevator and in the corridors of each floor.

"The surveillance system in this community is very complete. There are surveillance cameras in every corner of the courtyard of the community, which basically achieves full coverage. There are surveillance cameras in the elevators in every building, and there are surveillance cameras in the corridors on every floor. Except for the walking stairwell In addition, there is no monitoring, and there are almost other places.”

Zhang Yaoming followed behind Chen Yan, introducing the monitoring situation in the community in detail.

"After Wang Luyao came home from get off work last night, we reviewed the surveillance video of the whole night, and there were three people in the surveillance."

"One is the property cleaner, who cleaned up and left after mopping the floor in the corridor."

"There is another person who is Wang Luyao's neighbor. He came home from get off work at 9:30 last night and didn't leave home until 8:30 in the morning."

"The last person is Wang Luyao's mother. When she went to Wang Luyao's house this morning and found Wang Luyao dead, she called the police."

After talking, the two came to the monitoring room of the property company.

The monitoring room is very large, and on a super screen are the monitoring images of various cameras in the community.

"Call out the video of Wang Luyao going out during the day yesterday, and play it at 32x speed."

In the monitoring room, there were already detectives from the Dan City Police Department here. Hearing Chen Yan's order, he quickly operated the computer to retrieve the video.

The reason why Chen Yan retrieved the video from this point in time was because Wang Luyao had a video chat with her husband the night before, and went to work during the day, so she can be sure that there was no problem at home before Wang Luyao went to work yesterday.

But after Wang Luyao left, there was a possibility of outsiders entering at every time point.

Soon, the video will be retrieved and started to play.

The speed of 32 times is very fast, and other people can only see the jumping of the screen, and they can't see the specific situation at all.

Chen Yan's visual gene lock was activated immediately, successfully capturing and analyzing all the images on the big screen.

In fact, most of the surveillance images are static images in the corridor.

This is not a commercial area, except for the cleaning staff, it is the residents.

The building where Wang Luyao lives has two floors and five households, four of which are occupied and one is vacant.

At 8:10 yesterday morning, after Wang Luyao went to work, four more people appeared in the next hour.

Three are Wang Luyao's neighbors, and there is a cleaner who does the cleaning.

After that, for a whole day, there was a static picture in the corridor.

"stop!"

Suddenly, Chen Yan stopped the video: "Go back 30 seconds."

"Yes!"

The detective in charge of the operation immediately rewinds the video for 30 seconds.

What appeared on the big screen was a black still image.

"what's going on?"

"Oh, this is the system restart screen."

The young man in security uniform standing next to the detective operating the computer is the monitoring room monitor on duty today.

"Hi, officer. My name is Qiao Taining. I'm the security guard on duty today. This is the picture of our surveillance system restarting."

List

Yan looked at the time, it was 12 noon.

"Why does the system restart, does it restart every day or only yesterday?"

.2ksk.

"This is restarted every day. There are too many monitoring devices in our community, but the storage capacity of the server is limited. Every day at 12 noon is the automatic restart time set by the system. I heard from the maintenance staff that it is to clean up the garbage and keep the system running smoothly. .”

"How long will it take to restart?"

"five minutes."

five minutes?

Chen Yan looked at the big monitoring screen: "Go ahead."

"Yes!"

An hour later, Chen Yan watched all the surveillance videos.

Problem found.

The murderer was neither a ghost nor entered Wang Luyao's house out of thin air.

The other party must be very familiar with the restart of monitoring in the community, so they took advantage of the 5 minutes.

The murderer should have entered Wang Luyao's home at 12:00 noon yesterday, and then waited for Wang Luyao to come home from get off work and kill him.

However, according to Chen Yan's observation of the door at Wang Luyao's house just now, the other party did not use violence or other technical means to open the door.

With a high probability, the other party entered the room with a key.

five minutes...

The community where Wang Luyao lives is not big, and the building where Wang Luyao lives is very close to the gate, with a height of 4 floors.

During this time, the other party had time to completely avoid all monitoring and enter Wang Luyao's house. Therefore, Zhang Yaoming did not find any doubts in the monitoring of the investigation.

One is that the time period of Zhang Yaoming's investigation is not right, but because the other party may escape within 5 minutes, so the monitoring.

However, if the other party can go in and escape the surveillance, what about coming out?

Why did the murderer come out so silently?

The surveillance video in the community is restarted at 12:00 noon every day, with a 24-hour cycle.

If the other party entered Wang Luyao's home at 12:00 noon yesterday, how did he leave after killing Wang Luyao?

You know, Wang Luyao's mother arrived at Wang Luyao's house at 8 o'clock this morning, and then called the police.

Therefore, the other party has no time to wait for 12:00 noon today until the monitoring system restarts again.

How did the other party do it?

Is it fishing in troubled waters?

Chen Yan just saw the scene after Wang Luyao's mother called the police this morning.

Before Zhang Yaoming led the team to arrive, the first to arrive was actually the security guard.

Hearing the death, more than a dozen property personnel in the community, including security guards, rushed up first.

There are a total of 12 property management personnel in the video, which Chen Yan remembers clearly.

After Zhang Yaoming arrived, in addition to the detectives, the 12 security guards came out of the room one after another.

Not one more person.

In the video, after Wang Luyao's mother opened the door and saw the dead body, she collapsed to the ground without entering the room at all.

Then after shouting loudly, he called the police, and then security came in.

Chen Yan originally guessed that if the murderer was a staff member in the community, he would probably hide in the room and then take advantage of the chaos to leave the scene.

However, the number of property personnel has not increased.

12 people, or 12 people.

This is strange.

The loophole for the murderer to enter the room has been found, how about leaving?

How did he leave?

Can't find a way for the other party to leave, UU Reading This is equivalent to a murder case in a secret room.

or just

It is impossible to determine whether someone sneaked into Wang Luyao's house at 12 o'clock yesterday, taking advantage of the timing of the restart of the surveillance system.

Even though the spots on the back and thighs of Wang Luyao's corpse told everyone that after Wang Luyao died, she once sat on a person.

But how did this man get into the room and how did he get out?

evidence!

If there is no evidence, there is no way to kill the corpse and tell Chen Yan the clues.
