After the inspection in Feng Yuhan's 510 dormitory failed, we could only hope for the monitoring facilities in the corridor.

When you come to the doorman on the first floor, if you want to access the surveillance, you need a high-privilege password, and this teaching director has a password.

The doorman's eldest lady looks almost sixty years old, and she must not understand how to operate the computer in the guard's room, but this teaching director is very skilled, and it seems that she must often come here to call up the surveillance.

"Which day are you going to watch?" The Dean of Students turned back to me and asked.

"Four days ago." I said in a deep voice, because according to my classmates at school, the last time they saw Feng Yuhan was four days ago.

The dean nodded, and soon the operation was done, she called up the surveillance video from four days ago to show us, and she stood up and stepped back far away.

I watched her behind the Dean of Education during the surveillance period, and she did not have the time to make changes to the surveillance footage.

After the monitoring was retrieved, Li Meng and I stood in front of the computer screen to check the video of the day, and vaguely heard not far behind us, the doorman asked the dean in a low voice: "Who are these two people?" ”

"They're cops."

Even though the dean's voice was low, I could hear their conversation clearly.

"Police?" The doorman let out a low exclamation, and then asked in horror, "Won't they be here to investigate......"

The doorman's words were only halfway through and she didn't continue, probably stopped by the gesture of the teaching director.

These two people are too strange, aren't they, what are they muttering? What are they worried about us investigating?

But these things can only be guessed by us, because if they are worried, they will not tell us the truth.

Their current thinking is, let's check, find out, and pull it down if we can't find it, but I'm not sure what they are talking about is Feng Yuhan's disappearance.

But no matter what, this school, this dormitory building, this 510 dormitory, there must be some secret hidden by no one else.

There were no valuable clues in the surveillance video, so we fast-forwarded the video and our goal was to find Feng Yuhan's shadow.

Soon, the surveillance video showed that at two o'clock in the afternoon of the same day, Feng Yuhan appeared in the surveillance video. She was carrying a black bag in her hand, she should have just returned from shopping, and then she walked straight to the door of her 510 dormitory, took out the key to open the door, and walked in.

Judging by her demeanor in the video, nothing happened to her, just like peacetime.

Now that Feng Yuhan is locked in the 510 bedroom, we have accelerated the video by four times, and our eyes are firmly locked on the 510 bedroom, as long as Feng Yuhan leaves the dormitory, we will find out immediately.

The video was already 32 times faster, and the time in the video also flew by, and it was soon found that the lights in the hallway of the bedroom were turned on, and the surveillance video showed that the time was already six o'clock in the evening.

After a while, the surveillance video suddenly went black.

Li Meng immediately tapped the spacebar, and the time was seven o'clock in the evening.

We took a closer look at the video and found that it wasn't the surveillance probe that suddenly broke, but that someone had blocked it.

From the video, it can be clearly seen that the surveillance probe is covered by a piece of something similar to a towel in a dead angle.

However, the towel is not tightly covered, and there is an area in the lower right corner that can be used to check the situation in the hallway.

"Zoom in."

As soon as I finished speaking, Li Meng had already taken the lead in enlarging the only monitoring probe area that could see the situation in the corridor.

I don't know if it's a psychological effect, but I always feel that during this period of time when the monitoring probe is covered, people come and go in the corridor, and the footsteps are very dense, as if there are thousands of troops in the corridor.

It's a pity that we can only peek into what is happening in the corridor through one corner, and we can't get the whole picture.

At that moment, we suddenly saw a hand propped up against the wall from the corner of the surveillance footage.

Immediately afterwards, we saw someone in the corner of the surveillance video carrying a large item on his shoulder in the corridor, judging from the large object, it is likely to be Feng Yuhan wrapped in the carpet!

If the big thing that was carried on someone's shoulders was Feng Yuhan, this would not be a simple case of missing persons, but a homicide case.

"You can notify the criminal police team to investigate and see if fingerprints can be extracted on that wall. Also let them take the rappel rope and I'm going to check that garbage chute. I commanded.

Twenty minutes later, the criminal police team arrived at the scene, but none of the big brothers from the serious crime team came, and it is estimated that they heard that I took private work, and they didn't come, which was really not interesting.

But having said that, this case was not originally under the jurisdiction of the Serious Crimes Unit.

When the criminal police team arrived at the scene, they immediately set up a simple rope drop device in the garbage chute in the corridor, and at the same time took fingerprints on the wall where the hand was propping up in the surveillance footage.

"Will there be a clue here?" Li Meng looked at the bottomless garbage chute and asked me in disbelief.

To be honest, I wasn't entirely sure, but after a closer look at the environment of this dormitory building, it was the only suitable place to dump the body.

After killing Feng Yuhan, the murderer wrapped Feng Yuhan's body in a blanket and threw it into this garbage chute. But again, the question is, where did the body go after it was thrown into this garbage chute?

Either way, it doesn't hurt to go down and take a look.

After the equipment of the rope drop is erected, the following is the person who will drop into the garbage chute.

I looked at all the people present, then at the bottomless garbage chute, and finally at Li Meng.

Li Meng looked at me in a daze, then at all the criminal policemen around him in a daze, and finally looked at this bottomless garbage chute.

"Li Meng, you are so slender, I'm afraid this difficult task will be handed over to you. We're big guys, let alone going down from this chute to the outside of the building, we'll get stuck as soon as we get in. I smiled and looked at her earnestly.

"Huh?" Li Meng grinned and hesitated, but quickly nodded, and without saying a word, he put on the rope descent suit.

After all the equipment such as hard hats and goggles were put on, Li Meng took a long step and sat on the garbage chute.

"Stay safe." I tapped him on the shoulder and beckoned everyone to get started.

The rope stretched little by little, and Li Meng entered this bottomless garbage chute......
