Maguxiang Community.

The property owner pulled out the surveillance probe near the ventilation station.

"The ventilation station is close to the entrance and exit of Area A, and there is a monitoring probe along the street and inside, which can basically be accessed."

The security guard in charge of surveillance told the police.

Modern people basically keep their mobile phones away, let alone the boss who runs a breathing station alone.

The cell phone was not found at the crime scene. It can be roughly determined that the murderer took the cell phone away, which is inferred as a "homicide" case.

"Forensic judges that the death time is 3 to 7 days, so we will pay a little more insurance and then 1 day before. We will start watching the surveillance video eight days ago."

Hook said to the security guard.

Deng Bin stood behind and watched the surveillance video together.

On the eighth day, it can be confirmed that Sun Silei is still alive and has had video proof of entering and leaving the ventilation station.

The playback rate is played at 6 times the speed. The time in the upper right corner of the video spans another day, and it is 21:27 pm six days ago.

During the surveillance, a hunched man appeared at the door of the ventilation station and pushed the door and walked in.

It’s not Sun Silei. After Sun Silei went out to deliver a gas tank at night, he did not go out again for the time being.

"Who is this?"

Hook quickly pressed the pause and began to play back at normal speed. This was the first time in the surveillance video within two days that people other than the deceased entered the ventilation station.

Continue to press the double speed button.

At 21:45, the man walked out with a bicycle pushing a gas tank tied to the back seat of the bicycle.

This bicycle is confirmed to be Sun Silei's. Usually, Sun Silei uses this bicycle to deliver gas tanks to residents in the community.

This is also the first time in the surveillance video within two days that someone came to pick up the gas tank instead of calling Sun Silei to come to the door.

Deng Bin and Hook frowned at the same time, and noticed something was wrong.

Recording is played forward at twice the speed.

At 23:30, Sun Silei did not come out during this process, and the man riding the bicycle came back. There was a gas hanger tied to the back seat of the car. He lifted it down with one hand and put it into the ventilation station. The bicycle was then pushed in.

After 2 minutes.

At 23:32, the person walked out and brought the door of the ventilation station and left.

"It's not right~" Hook looked at Deng Bin, then pressed the double speed button to quickly go forward.

One night passed, and then at noon on the second day, and then continued until the next night that the door of the ventilation station was closed, and Sun Silei did not appear in the surveillance again.

This proves that from last night to now, Sun Silei has not gone out and has been staying in the house for 24 hours.

So are the dead or living people staying in the house?

Continue to fast forward and play quickly backwards. The door of the ventilation station has not been opened until this morning, a thief sneaked in at the door and opened the door, and then ran out in panic and vomited at the door.

so……

"Diet time, 6 days ago, between 21:27 and 23:32 points, there are two periods between them, which are the segments where the person enters and exits twice. I personally prefer the previous time, that is, 21:27 and 21:45 points, Sun Silei has been killed in the house by this person."

This surveillance video is enough to tell the truth. Sun Silei died six days ago, and the person who came in and out of the video is naturally the murderer.

Hook made a judgment on the video, and the police officer next to him took a pen to record all the time nodes that appeared in the video.

Deng Bin basically agreed with Hook's judgment, and what puzzled him was the murderer's actions after the murderer was.

"I stayed in for 18 minutes for the first time. These 18 minutes should be the time for the murderer to commit the murder, but what did he do after he killed someone?"

Deng Bin frowned. In the video, the man did not run away in panic, nor did he find a way to bury the body. Instead, he pushed a bicycle tied to a gas tank, went out to stay for more than an hour, and then returned.

After returning the bicycle and gas tank, stay for another 2 minutes and leave the community completely.

"Isn't it just going to deliver gas?" Huke said suspiciously.

The air suddenly became silent!

This answer is too weird, but it seems to be the only possibility that can be explained at present.

"I'm the murderer for the time being. Let's see what he's doing. In addition, I'll ask someone from the technical department to come over, copy and record the video, and take it back to process the image quality."

The resolution of the surveillance video was not clear enough, and it was night and it was raining. The man hunched over and lowered his head throughout the whole process, and he couldn't see his face clearly during the surveillance.

While giving instructions to the police officer next to him, Hook drew up surveillance videos along the way to see where the murderer riding a bicycle went.

Finally, the clue is frozen in the deepest blind alley in Magu Lane, with the door number 4 13.

You can see in the surveillance video:

In the dim night rain, the wheels of the car stepped through the bumpy water holes, and the heavy gas tank was tied with hemp ropes on the back seat of the car and swayed slightly as the car swung.

In front of the self-built building on No. 4 13.

The bicycle stopped, untied the tied rope with a hunched body, dragged the gas tank into the yard, and fell to the ground with a swaying bicycle, and the wheels idly splashed rain onto the plastic bag.

Yes.

This person did not come here directly, but bought a bag of instant noodles while passing the convenience store.

He bent over and dragged the gas tank into the yard. The time was 21:53.

Then at 23:27, he walked out again with a gas tank, pushed up the bicycle and re-tied the gas tank, rode the bicycle and left the road and returned to Huanqi Maguxiang Station, returned the bicycle and gas tank, and left the community.

"The gas tank that was dragged in was full, the ones that came out were empty, and the instant noodles I bought were not brought out, nor did the plastic bags."

Hook said before and after sharp eyes.

Deng Bin frowned and thought.

This person stayed at the ventilation station for 18 minutes before a murder occurred.

Then he stayed on No. 4 for an hour and 34 minutes, what did he do?

"Is that the murderer's residence? Did you go home to eat after buying instant noodles?"

Hook and Deng Bin looked at each other, probably half of them guessed correctly.

The property then fell out of the system and the registration information of the owner showed that "the owner of No. 4, Magu Lane 13 is Chen Zhuo, a male, with a contact number of 166xxxxxxxx, living alone and not renting out."

“What is the owner of No. 4 13?”

Deng Bin's pupils suddenly contracted into pinholes. He pulled two hairs away inattention, and the back of his spine was filled with coldness.

"I originally thought that the murder of the ventilation station was isolated, but finally there was no connection with Chen Chao. As a result, I just turned around and seemed to be able to get involved with Chen Chao again."

But,

The man in the surveillance video is not Chen Chao!

Although the appearance is not clear, the body shape is not Chen Chao, and he looks older.

Who could it be?

The psychologist Chen Zhuo and Chen Chao should have a connection, so what is the connection between this murderer and them?
