Chapter 235: Murder in a Closed Room

The video ends here.

Chen Yan put the tablet on the table and looked at Zhang Yunhu doubtfully: "Team Zhang, this is..."

There is a date on the video, which is July 28 last year.

Why are you showing last year’s video to yourself now?

"This is a case handled by the Yinglu City Detective Team at the end of July last year."

Zhang Yunhu took out a cigarette and handed one to Chen Yan: "At that time, I originally thought it was a simple disappearance case, but after opening the wooden door, not only were two people found in the house, but also a body."

"Both of the two people alive identified the other as the murderer, but there was no substantial evidence."

"Besides, this brick building in the warehouse has only one door that can lead in and out."

"Half a year has passed since the case was investigated, but it still has not been solved."

"Hu Xueying, the captain of the Yinglu City Detective Team, called for help and wanted to see if you had time. Come over and have a look."

…

After leaving Zhang Yunhu's office, Chen Yan already had a file in his hand.

How should I put this case?

Somewhat weird.

Yes, it's weird.

July 28, Logistics Warehouse Park in the southern suburbs of Yinglu City.

A murder occurred in a brick building inside an abandoned warehouse.

There were two other people with the deceased.

The brick house where the crime occurred had a wooden door as the only entrance and exit.

This turned out to be a typical secret room murder case.

So far, there has been no progress in the case.

The two people who were locked up in the brick house with the deceased at the same time identified the other as the murderer.

However, neither of them had a motive for committing the crime, and there was no evidence of committing the crime.

So, who killed the deceased?

Taking out his mobile phone, Chen Yan dialed Shen Yunyi's number: "Yunyun, I'm going on a business trip to Yinglu City in the next few days."

"Well, okay, stay safe, I'll wait for you at home."

That's what Xiao Yujie is good at, she is sensible.

Chen Yan has always been fully supportive of his work.

Just leave.

In the afternoon, Chen Yan took only Zhao Bing to Yinglu City.

This case occurred before the Major Crime Team was established, so for now, Chen Yan will not investigate the case in the name of the Major Crime Team.

Instead, he went to Yinglu City as a special adviser to the Liao Provincial Detective Brigade.

Moreover, Hu Xueying, the captain of the Yinglu City Detective Team, asked Chen Yan for help in the case itself.

It is worth mentioning that the captain of the Yinglu City Detective Team, Hu Xueying, is the only female detective team captain in the Liao Province Detective Brigade.

This man was once a legend.

It is said that when he was young, he once went undercover in a criminal gang alone, and once won a second-class personal merit.

In the police industry, most female detectives work in the back office.

He went out in the field, worked as an undercover agent, and won the second-class personal merit.

Hu Xueying is much more powerful than most men in the Liao Province Detective Brigade.

However, Chen Yan was slightly surprised when he saw this heroic girl.

The two met during a meeting of the Liao Provincial Detective Brigade a few days ago.

At that meeting, Hu Xueying was heroic and full of energy, but now, she has thick dark circles under her eyes and looks tired.

"Captain Hu, what are you..."

Hu Xueying shook her head and smiled: "In the past few days during New Year's Day, I reviewed and studied the secret room murder case in July."

"I haven't slept for several days, which made Team Leader Chen laugh."

"This time, please give me some guidance from Team Leader Chen."

Chen Yan waved his hand: "Captain Hu, you're welcome. That's it. I've already read the file. Let's go directly to the scene."

"Okay," Hu Xueying nodded: "The scene has been closed and preserved. Let's set off now."

Half an hour later.

Chen Yan came to Yinglu City Nanjiao Logistics Park.

"This logistics park is the only large-scale logistics park in Yinglu City."

Entering the logistics park, Hu Xueying began to introduce Chen Yan: "This logistics park covers a large area and the personnel exchanges are very complicated."

"The warehouse where the crime occurred was built twenty years ago. The logistics company at that time closed down, and the warehouse became idle."

The warehouse where the crime occurred is located in the northeast corner of the logistics park.

The warehouses in this area were built quite a long time ago.

There are no cameras installed nearby either.

A new lock was put on the door: "The lock at the time of the crime has been collected in the evidence room. This lock was later replaced by our detective team."

Chen Yan nodded. The lock at that time was not an ordinary iron lock, but a universal lock opened with a triangular key.

Entering the factory building, it is relatively rundown.

There is a damaged hole on the top of the factory building, and it is empty except for some broken bricks.

Entering the factory building, in the northeast corner is the red brick house where the crime occurred.

"We inquired about the information on this factory," Hu Xueying pointed to the red building in the corner: "That red brick building was an office back then. It originally existed. When the factory was built, it was expanded into it."

"We conducted a very detailed inspection of this red brick house, and we can confirm that there is only one exit through the wooden door."

Speaking of the only exit of the wooden door, Hu Xueying's expression changed slightly.

This is the weird part of the case.

Entering the red brick house, Chen Yan immediately turned on the olfactory gene lock and the visual gene lock.

The case occurred at the end of July last year.

According to the records, on the morning of July 28, Zhang Baoshan, the security captain of this area, called to report the crime.

He said he heard calls for help while on patrol.

Because he had drunk some wine that night, he thought he was hallucinating at first, so he didn't take it seriously.

However, the next morning, he came to the abandoned factory again and found that the universal lock had been opened. Thinking of the cry for help he heard last night, Zhang Baoshan immediately called the police.

Next, Chen Yan saw the scene in the video in Zhang Yunhu's office.

The factory lock did show signs of being opened.

The wooden door of the red brick house was wrapped with brand new iron wire.

From the images in the video, the main reason is that there is no locked lock on the wooden door, and it is impossible to lock it with a lock.

Therefore, the murderer used iron wire to wrap it to prevent the wooden door from being opened.

The smell at the scene...

There is no special residue.

Not only has half a year passed, even if the smell of the murderer was left at that time, it is impossible to distinguish it now.

There are still traces of iron wire wrapped on the wooden door, but now the iron wire has been taken back to the evidence room.

After a careful observation, Chen Yan walked into the red brick house.

This house has no windows.

Even though it was daytime, the house was still dark and the view was unclear.

Click.

"We later installed a temporary lighting."

After the light was turned on, the situation in the room was clearly visible.

The entire red brick house was only about 30 square meters.

In the corner opposite the wooden door was a shabby bookcase.

There were scattered bricks on the ground, and some dark brown marks.

Needless to say, the brown marks were recorded in the photos in the file.

This was the blood that splashed when the victim was killed.

The bricks on the ground were the murder weapon.

In the middle, there was a human-shaped outline, close to the bookcase.

"This human figure was the position of the victim after death."

Approaching the outline, Hu Xueying introduced to Chen Yan: "When we found the victim, the deceased was face down, and there were obvious blunt impact marks on the back of the head."

"According to the situation at the scene, the murderer hit the back of the deceased's head with a brick many times, which eventually led to the other party's death."

As Hu Xueying introduced, Chen Yan kept combining the photos in the file in his mind.

According to the traces of blood spray, direction and distance, and the position of the body, the murderer in Chen Yan's mind seemed to come alive.

The murderer rode on the dead body, picked up the bricks beside him, and began to hammer the back of the dead body's head.

Blood splattered on the wall, the ground, and even the murderer.

Moreover, after the crime, the secret room was opened, and the two survivors also had bloodstains on their bodies.

After all, it was a small place of only 30 square meters, only five or six meters long and wide.

When the murderer killed people, it can be said that he was committing the crime in front of the two survivors.

However, according to the description of the survivors, they were in a coma at the time and knew nothing about these.

After observing the surroundings, Chen Yan raised his head and looked at the roof of the house.

"The roof of the house is covered with waterproof tarpaulin," Hu Xueying saw Chen Yan's actions and naturally understood what Chen Yan was thinking.

But Hu Xueying and others had already checked the roof in detail.

"Although it has been a long time and has aged severely, there are no signs of damage or repair."

No...

The wooden door, Chen Yan just observed it carefully.

The door frame is made of old wood. Although the inlay between the door frame and the red brick wall is not very tight, the gap is full of dust and there are spider webs in the middle.

Chen Yan did not find any traces of assembly and disassembly.

The hinges between the door frame and the two wooden doors have long been rusted, and there is no trace of twisting the screws on them.

Therefore, the possibility that the murderer tampered with the wooden door is basically ruled out.

As for the roof, Chen Yan still trusts Hu Xueying's ability.

Since the other party said that it has been checked, there is a high probability that there is no problem.

However, the roof is fine, the wooden door is fine, how did the murderer kill people?

Could it be that the victim was really killed by the survivors?

Don't be funny.

Impossible.

Why?

Because when they were found, the wooden door was wrapped with wire outside.

If one of the two survivors was the murderer, then who tied them into the red brick house.

Who wrapped the wooden door with wire?

Chen Yan walked to the wall and stretched out his hand to turn around the wall.

The rough friction feeling is very real.

After a round of investigation, the red bricks are real red bricks.

The wooden door is fine, the roof is fine, and the red bricks are fine.

So...

How did the murderer do it?
