Chapter 235： Secret Room Murder

The video ends here.

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

The date on the video is July 28 last year.

Last year's video, how can I show it to myself 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 it to Chen Yan: "At that time, I thought it was a simple disappearance case, but after opening the wooden door, not only two people but also a body were found in the house."

"The two living people both identified the other as the murderer, but there was no substantial evidence."

"Also, in this brick building in the warehouse, only that door can enter and exit."

"It's been half a year since the case was investigated, but it still hasn't been solved."

"Hu Xueying, captain of the Yinglu City Detective Squad, called for help and wanted to see if you had time, so go check it out."

...

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

How about this case.

Kind of weird.

Yes, it's weird.

On July 28, the logistics warehouse park in the southern suburbs of Yinglu City.

A murder occurs in a brick building in an abandoned warehouse.

And with the deceased, there are two others.

The brick house where the crime happened has only a wooden door as the only entrance and exit.

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

So far, the case has not progressed.

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

However, neither of them had a motive for committing the crime, nor did they have any evidence of committing the crime.

So, who killed the dead?

Taking out his mobile phone, Chen Yan called Shen Yunyi: "Yunyun, I'm going to Yinglu City on a business trip these days."

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

That's right, Miss Yu, and she's sensible.

Chen Yan's work has always been fully supported.

Just go.

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

This case happened before the establishment of the serious crime team, so, at present, Chen Yan will not investigate this case in the name of the serious crime team.

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

Moreover, the case itself was also made by Hu Xueying, the captain of the Yinglu City Detective Team, who asked Chen Yan for help.

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 Team.

This one 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 profession, female detectives mostly do back-office work.

Going out to work, being an undercover agent, won the personal second-class merit.

Hu Xueying is much stronger than most men in the Liaoning Province Detective Brigade.

However, Chen Yan was slightly surprised when he saw the hero of the female middle school.

A few days ago, the two met in a meeting with the Liaoning Provincial Detective Brigade.

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

"Captain Hu, you are..."

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

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

"This time, I also ask Team Leader Chen to give more guidance."

Chen Yan waved his hand: "Captain Hu is being polite, so let's go. I have read the dossier, let's go directly to the scene."

"Okay," Hu Xueying nodded: "The scene has been closed and preserved, let's go now."

After half an hour.

Chen Yan came to the logistics park in the southern suburbs of Yinglu City.

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

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

"The warehouse where the incident occurred was built 20 years ago. At that time, the logistics company closed down, and the warehouse was idle."

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

The warehouses in this area are relatively old.

There are also no cameras installed nearby.

On the door, a new lock was changed: "The lock at the time of the crime has been collected in the evidence room. This lock was later changed by our detective team."

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

Entering the factory building, it is relatively dilapidated inside.

There is a broken hole in the top of the factory building, which is empty except for some broken bricks.

Entering the factory building, in the northeast corner, is the red brick house at the time of the incident.

"We checked the information of this factory building," Hu Xueying pointed to the red house in the corner: "That red brick house was an office back then, and it originally existed. When the factory building was built, it was expanded inside."

"This red brick house, we have carried out a very detailed inspection, and we can be sure that there is only one exit through the wooden door."

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

That's the weirdness of the case.

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

The case happened at the end of July last year.

According to the dossier, on the morning of July 28, Zhang Baoshan, the security captain in this area, called to report the case.

Said that while patrolling, I heard a cry for help.

Because he drank a little wine that night, he thought he had auditory hallucinations at first, so he didn't take it seriously.

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

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

The lock of the factory building does have traces of being opened.

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

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

Therefore, the murderer used wire entanglement to prevent the wooden door from being opened.

Scent of the place...

There is nothing special left.

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

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

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

This house has no windows.

Even though it was daytime, the house was still dark and the vision was not clear.

click.

"We installed a temporary light later."

When the lights are turned on, the situation in the room can be seen at a glance.

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

In the corner opposite the wooden door is a dilapidated bookcase.

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

Needless to say, brown marks are recorded on the photos of the dossier.

This is the blood spattered when the victim was killed.

The bricks on the ground are the murder weapons.

In the middle, is the outline of a human figure, near the bookcase.

"This human figure is the location of the victim at that time after his death."

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

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

Following Hu Xueying's introduction, Chen Yan kept combining the photos in the dossier in his mind.

According to the traces of the blood spray, the direction and distance, and the fallen position of the corpse, the murderer in Chen Yan's mind seems to have come to life.

The murderer rode on the deceased, picked up the bricks around him, and began to smash the back of the deceased's head.

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

Moreover, after the incident, the secret room was opened, and the two survivors also had bloodstains on them.

After all, it is a small place of only 30 square meters, with a length and width of only five or six meters.

When the murderer kills, it can be said that he committed the murder in front of the two survivors.

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

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

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

But the roof Hu Xueying and the others have already inspected it in detail.

"Although it has been a long time and has aged badly, there is no sign of damage or repair."

No……

The wooden door, Chen Yan just observed it carefully.

The door frame is made of old wood, and the inlaid between the red brick wall is not very tight, but the gap is densely covered with dust, and there are spider webs in the middle.

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

There is also the hinge between the door frame and the two wooden doors, which has long been rusted, and the screws on it have not been twisted at all.

Therefore, the possibility of the murderer doing things on the wooden door is basically ruled out.

On the roof, Hu Xueying's ability, Chen Yan can still trust.

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

However, the roof is no problem, the wooden door is no problem, how did the murderer kill the person?

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

Give me a break.

impossible.

Why?

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

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

Who was it that wrapped iron wire around the wooden door?

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

Rough friction feeling, very real.

After a circle, the red bricks are real red bricks.

No problem with wooden doors, no problems with roofs, no problems with red bricks.

so……

How did the murderer do it On the day of the 100th blind date, the blind date was arrested≈039;);
