Zhong Tianzheng glanced at the person in charge of the command scene and put forward his idea of going upstairs to have a look. The other party didn't stop him and continued to command the scene.

Meng Yichuan's room is on the fourth floor.

Instead of taking the elevator, they chose to take the fire passage. The main purpose is to observe whether the monitoring facilities and equipment of the corridor are complete.

According to the front desk of the apartment management office, the other party is a new tenant who has moved in for half a month. If it is him, he should avoid the elevator and choose to go up from the fire passage.

indeed.

There is no monitoring in the fire passage.

This kind of place is different from the shopping mall. Under the circumstances of cost and other capital savings, they do not install monitoring equipment.

Go up the stairs.

The room in the corner of the fifth floor has been opened by the apartment management office. There are police officers searching the house.

Two people enter.

The interior is very clean and tidy. No one has moved in, and there is no trace of life. Many of the basic furniture are covered with a layer of dust.

In other words.

Renters have never moved in after renting a house.

"Did you find anything?"

Zhong Tian nodded and asked the comrade standing on the windowsill.

"It's basically certain that the killer went down from here."

The policeman glanced at Zhong Tianzheng and said to Ah Xiang, "he should have tied a rope into the shape of a ladder, tied one end indoors and stepped down the window."

Follow the direction of the officer's finger.

There are two obvious strangulation marks at the foot of the bed next to the window. If you look carefully, you will find that there are residual fibers of nylon rope on it.

There are few useful clues in the room. We can only verify how the killer got down, and then there are no other clues.

"We have confirmed the tenant information. The ID card is false. There is no such person."

The other party explained again: "and this is not the most critical point. The most puzzling thing is that we checked the monitoring on the day of the incident and even a few days before the incident. It shows that no one has entered the room in these days."

"No one went in?"

Zhong Tianzheng couldn't help picking his eyebrows.

"You can see for yourself."

The policeman put down a sentence and went busy again.

Zhong Tianzheng took over the computer and began to jump to check the surveillance video.

Shown in video.

The last time the murderer left the room was three days ago. Three days ago, the man in a mask and cap never came in after he left the room.

In that case.

So how did he get out of the room last night and commit the crime?

After all.

All the clues in the room show that the murderer went down from upstairs.

This is very strange.

How can someone commit a crime if they don't go in?

Zhong Tianzheng rubbed his eyebrows, frowned and thought.

"Ah Zheng, look here."

Ah Xiang suddenly made a noise, pointed to the computer screen and said, "at more than two o'clock last night, the camera was suddenly blocked."

"Blocked?!"

Zhong Tianzheng raised his eyebrows and came to the spirit.

"Blocked by a balloon."

Zhong Tianzheng looked at the past. At 2:10, several pink boar Paige balloons suddenly rose in front of the monitoring, unbiased and stably blocking the camera picture.

Zhong Tianzheng quickly dragged the monitoring progress bar and found that the camera had been blocked by the boar Paige until six o'clock in the morning.

Then.

An aunt who cleaned the apartment appeared in the surveillance.

In other words.

These wild boar Paige was deliberately put up. She was pulled apart until her aunt who was engaged in sanitation saw it.

Zhong Tianzheng nodded thoughtfully: "come to the apartment cleaner."

Apartment cleaning aunt is not full-time in this apartment.

The pattern of her apartment is: she will come to clean the apartment on odd days, and she still has other things to do at other times. Many apartments are now operated in this way to save costs.

While waiting for cleaning.

Zhong Tianzheng is not idle.

Instead, he dragged Xiang around on the fifth floor.

"Are you looking at the apartment layout?"

Ah Xiang glanced at Zhong Tianzheng around and guessed his idea.

"Yes."

Zhong Tianzheng simply replied and didn't say anything more.

In the past, the apartments were basically one by one, surrounded by complex buildings. They were like a village in the city, and the surrounding environment was very poor.

The layout of those apartments is generally in the shape of "back".

in other words.

When you walk in from the door, the apartment is surrounded by rooms, and the inner corridor is also a room, which is usually called the inner window room. A circle of outer window rooms surrounds a circle of inner window rooms.

The windows of the room are opened in the corridor. The indoor air of this kind of room is very bad, and the sound insulation is also very poor, but the rent is relatively cheaper.

of course.

This kind of apartment has become a thing of the past.

Shangnan city has made great development moves in the past two years. Most of these apartments have been demolished, so the existing apartments generally follow the high-end route.

Looking at the single family apartment building from a distance, it looks like a hotel. Compared with those apartments, the environmental facilities and equipment are much better, and the rent is naturally more than seven or eight hundred to one thousand.

The layout of this hotel style apartment is also quite atmospheric. It is this kind of split door of the hotel. It has a II shape layout. There are rooms on the left and right sides and an aisle in the middle.

Zhong Tianzheng walked straight along the corridor and walked down in a circle. He had a general number in his heart: "did you find any characteristics?"

Ah Xiang tilted his head: "there are few tenants on this floor?"

"Yes."

Zhong Tian nodded: "the occupancy rate of tenants on this floor is less than average, and most of them are close to the elevator. There is a certain distance from the room rented by the murderer."

Ah Xiang seemed to get to the point and said, "the killer's room is close to the innermost position. The most important thing is that his room is a single family. There is no room opposite him when he opens the door. His room corresponds to a stairway."

"Yes!"

Zhong Tianzheng nodded: "no accident, he left the scene from there."

On the way to P & G, while waiting, Ah Xiang couldn't help chatting: "Hey, why don't you rent out all the rooms when there are so many vacant rooms in this apartment without a preferential price, such as how much rent reduction in the first month?"

"Hehe, you are still too naive."

Zhong Tianzheng shook his head and smiled without saying anything.

exactly.

Ah Xiang asked this question. Only people like her who haven't rented a house outside will ask this question.
