The locksmith brought by the police opened all the door locks in Professor Pei's house.

It's also very magical that all the rooms in the house are locked in broad daylight. I don't know if Feng Guanghua locked them before he died, or if the murderer locked them before he left.

It's hard to say who locked the other rooms. The door to the second bedroom where Feng Guanghua died must have been locked by the murderer.

Things like secret rooms are just a trick played by a murderer who thinks he is smart. Often this kind of trick will only delay the police's efforts to solve the case, but in the end they still cannot escape the fate of being caught.

After checking every corner of the house, the police confirmed that there was no other living person in the house except police personnel.

Taking a closer look at the space structure and comparing the room type and usage area can also ensure that there are no secret rooms that can hide people.

The forensic doctor examined Feng Guanghua's body and found that only the head had wounds on his body, which should be fatal injuries.

Rust residue was collected from the head wound, and the murder weapon was confirmed to be an iron blunt instrument.

After the scene records were completed, the body was transported back to the police station for further investigation, while Xie Jingchen stayed at the scene to inspect and collect fingerprints and other evidence.

The door handles of several doors have been collected, and the comparison results have not been released yet.

After Xie Jingchen walked around the house, he went to the corridor.

Let’s not talk about the secret room in the room. That is not the most critical issue. The most critical thing is that in the eight minutes before and after Xiao Zhao left, the murderer had to complete a series of actions such as killing, creating a secret room, and escaping.

Eight minutes, the time is very tight, even killing a person is difficult to complete.

After Xiao Zhao returned to the downstairs of Pei's house, he did not see anyone going up or down the stairs.

When did the murderer go upstairs and when did he enter Pei's house?

Did the murderer quickly go upstairs to kill them after seeing them leaving Pei's house, or was he already hiding in Pei's house before they left?

Did the murderer finish killing everyone and leave within eight minutes? Where did he leave?

Xie Jingchen went to the community security guard to adjust the monitoring/control.

Although it is an old community, the security system has just been updated, and there are cameras that can capture the exits of each corridor of the building from the side.

It took an hour. Xie Jingchen watched the surveillance video at normal speed and then slow-played it again.

The surveillance video showed that from the time Xie Jingchen and Xiao Zhao went downstairs and exited the corridor until Xiao Zhao came back and stood outside the corridor, no one entered or left the corridor.

The murderer did not leave the corridor? Then how did he leave after killing the people? Is it so difficult that people can disappear out of thin air?

Xie Jingchen returned to the downstairs of Pei's house from the security office with questions.

First find the location of the camera and judge the camera's monitoring/control range based on the previously viewed video.

After walking around, I discovered that although the camera could capture people entering and exiting the corridor, it could not capture the stairs further in from the corridor.

Go down the stairs, if you don't go out of the corridor, go to the back of the stairs to the private garage on the first floor.

Not every private garage is connected to the corridor. Only the two garages marked with 201 and 402 on the door numbers lead to the stairwell, and a "back door" is installed in the stairwell.

This kind of old community without elevators only has residents on the second to sixth floors. The first floor, which is the ground floor, is the garage. The garage is purchased by the owner of the household voluntarily, and not every household has one.

Some garages are not used for parking after being purchased, but are renovated and transformed into small apartments that can be rented out or used by the elderly in the family.

Xie Jingchen went to knock on the door one by one, but no one answered. Then he recorded the situation and sent people to check the situation of the two garages. At the same time, he went around to the other side of the building to check the main entrances of these garages.

After the garage information was found and the owner of the household was called, the fingerprint comparison results came out.

The two garages that can be connected in this corridor correspond to household owners 201 and 402 respectively.

The residents of 402 are a family of three. The garage was converted into a house to take care of the sick grandfather at home. Because the old man's legs and feet are not good and it is inconvenient to go up and down the stairs, the old man was allowed to live in the garage on the ground floor.

Now, the 402 family is not at home. The husband is at work, the wife is accompanying grandpa for examination in the hospital, and the children are in school.

The garage room in 402 has a locked rolling shutter door in front, and the door leading to the corridor at the back is specially equipped with a tight security door, and cameras are installed in the home to check the elderly's condition at any time.

Their cameras can prove that no outsiders have entered or left the home.

The head of household 201 is a real estate speculator. He buys a house with a loan, rents it out after renovation, and then uses the rent to repay the mortgage. When the house price rises, he sells the house to make money.

201 and the garage of 201 under his household have been rented out as school district housing for key middle schools. They are very close to the school and are convenient for students to go to and from school.

This real estate speculator kept a spare key for himself, but he was not in the local area, so he only gave the tenant's contact information to the police.

Both tenants cannot be contacted now, and it is estimated that they will have to wait until after working hours before they can be contacted.

The fingerprint comparison results also came out. In addition to the fingerprints of Pei Chengjing and Feng Guanghua, the fingerprints of Zhou Yang and Su Ye were also compared in the room.

Zhou Yang died yesterday, so the suspicion must be ruled out. It can't be a vicious ghost seeking his life.

As for Su Ye, his suspicion is quite high because his fingerprints are basically all over the Pei family.

There are fingerprints left by Su Ye on the door handles, tables, chairs, toilets, and even the kitchen knife handles.

However, one thing is strange, that is, there are no fingerprints on the handle of the iron pot used for cooking.

After examining the iron pot inside and out, the police found that there was blood residue on the bottom of the iron pot. At the same time, the composition of the rust on the bottom of the iron pot was consistent with the composition of the rust remaining on the head of the deceased.

The murder weapon was found.

When the murder weapon, the iron pot, was found, it was placed on the stove. It had been simply cleaned, at least the fingerprints on the handle had been wiped away, and most of the blood stains on the bottom had been wiped off.

However, because the material at the bottom of the iron pot is very stubborn and difficult to clean up in a short time, they found the residue.

As soon as the fingerprints were compared, the police contacted Su Ye.

Su Ye was just like the last time Xie Jingchen came to see him, it took a long time before he came out of the laboratory.

However, he has numerous personal and material evidence that can prove that he has not left the laboratory today.

Regarding the police's question "Why were your fingerprints found at Pei's house?" Su Ye answered calmly.

"Professor Pei is my mentor. When he passed away, I naturally had to visit my teacher's wife and even help my teacher's wife arrange the funeral."

He also said: "Teacher Pei has no children in his life. I am the same as his biological son. The Pei family is equivalent to my family. I have fingerprints. Is there anything strange about it?"
