Chapter 236： Sort out the dossier

After leaving the red brick house, Chen Yan knew why Hu Xueying was so haggard.

The Yinglu City Detective Team has been investigating this case for nearly half a year. .

However, so far, there are still no clues.

The most important thing for murder in a secret room is to deduce the process of the murderer's murder, or how to do it in a secret room.

【Ding! The task of the strongest police training system is released. 】

[Detecting a murder case in a secret room, within a five-day period, completing the task and rewarding the parkour skill specialization, failure or overdue cancellation of the task reward. 】

Parkour?

Chen Yan was stunned for a moment, this skill was quite new, and it was indeed very useful.

When handling a case, it is inevitable to stage a pursuit battle.

Although Chen Yan relies on the genetic lock of system rewards, his physical fitness has long since changed.

However, if you master this skill, you will get twice the result with half the effort.

...

In the Yinglu City Detective Team, Chen Yan asked Hu Xueying to prepare an office.

All the evidence, files, and photos were sent to Chen Yan.

The deceased, Duan Zhongxin, male, 41 years old, was from Linshui Village, Panshan Town, Yinglu City. Before he was killed, he worked in Tongda Transportation Company as a truck driver, mainly responsible for delivering couriers.

According to the autopsy report, the direct cause of Duan Zhongxin's death was a severe blow to the back of the head with a blunt object.

Eventually lead to intracranial hemorrhage and death.

According to the analysis of the situation at the crime scene at that time, the murderer used a brick on the ground to kill Duan Zhongxin.

However, in addition to the fatal blunt force injury, Duan Zhongxin also had a smaller wound on the back of his head.

This wound was not formed by the blow of a brick.

It should be a kind of hammer blow.

The dossier records the speculations of the investigators at that time.

Duan Zhongxin should have been knocked on the back of the head by a hammer first, causing him to fall into a coma and transported to the red brick room of the warehouse.

Not only that, the detective in charge of the autopsy also detected the residual substance of ether in Duan Zhongxin's body.

This shows that the murderer once stunned Duan Zhongxin with ether.

This is a little strange.

Since Duan Zhongxin was knocked unconscious by a hammer, why did the murderer use ether?

Was it because he was worried that Duan Zhongxin would wake up in the middle?

Or is there another reason?

In addition to the deceased, there were two survivors at the scene.

Survivor No. 1, Yu Huihui, female, from Shanggang Village, 33 years old, works as a cashier at the Haolai Hotel in the logistics park.

this woman...

How should I put it, although she is already 33 years old, this Yu Huihui is very young.

The photos in the file were taken half a year ago.

The woman has a delicate face, a little baby fat, and looks like she is in her 20s.

Moreover, the woman's face is full of charm and looks very charming.

Although the eyes are not large, they seem to have hooks.

Even in the photos, there seems to be an illusion that the eyes speak.

Such a woman...

Ha ha.

Survivor No. 2, Tang Muqi, male, 56 years old, from a laid-off village, works as a security guard in the logistics park, and is a fellow villager of Zhang Baoshan, who reported the case.

This man has an ordinary face, nothing special.

The dossier is very detailed.

Moreover, when the detectives broke down the red brick house at that time, there was also a video shooting, but the video was blurred due to the light.

The specific time of the incident was 9:28 a.m. on July 28.

The detective who called the police at that time was called Li Tongyun. After hearing the sound of help in the red brick house, he immediately got pliers and cut the wire on the wooden door.

Yu Huihui and Tang Muqi were released.

At that time, Li Tongyun did not find the deceased Duan Zhongxin in the red brick house.

If it weren't for the blood splattered on Yu Huihui and Tang Muqi's bodies, the house would be rumbling in darkness, and maybe they wouldn't be able to find the deceased.

After that, Li Tongyun immediately reported to his superiors.

On the same day, the Yinglu City Detective Team started the interrogation of Huihui and Tang Muqi.

According to the confessions of Yu Huihui and Tang Muqi, both of them were dazed and knocked unconscious on the night of the 27th.

Yu Huihui got off work at around 11:30 p.m. on the 27th. Then, on the way home, she was restrained from behind and fainted with ether.

This should be true, because the detective detected ether residues in Yu Huihui's body.

Tang Muqi was in charge of patrolling the factory building in the adjacent area on the night of the 27th. According to his recollection, he was hit with a sap during the patrol, and then stunned with ether as well.

When you wake up again, you will be in darkness.

At that time, not only Yu Huihui and Tang Muqi, but the deceased Duan Zhongxin also woke up from a coma.

The three tried to find the exit together, but to no avail, because of exhaustion and fear, and the influence of the residual substances of the drug, several of them fainted again.

When he woke up, he was awakened by a knock on the door.

After that, it was Li Tongyun who interrupted the wire outside and rescued them.

However, at this time, Duan Zhongxin was already dead.

After that, Yu Huihui and Tang Muqi respectively identified each other as the murderer.

However, the evidence at the scene was not enough to prove that one of the two people was the murderer.

After the incident, the crime scene was not destroyed.

Judging from the later investigation records, after Duan Zhongxin was killed, the red brick house was the first crime scene, judging from the traces of blood spray, the direction and the autopsy report.

However, there were no fingerprints of Yu Huihui or Tang Muqi on the killing brick.

Both of them had bloodstains sprayed in the same direction.

This shows that when Duan Zhongxin was killed, the two were still in a coma.

Moreover, they are all in the direction opposite the wooden door.

Because the bloodstains of the two people are continuous.

This means that there was either a fourth person at the scene, in front of Yu Huihui and Tang Muqi, who killed Duan Zhongxin.

Either Duan Zhongxin killed himself by hitting the back of his head with a brick.

However, both Yu Huihui and Tang Muqi insisted that there were only three of them at the time, and there could be no fourth person.

Because, after they woke up in the dark, they began to **** for the exit of the house.

However, although they found the wooden door, they could not open it.

And Duan Zhongxin suggested that since someone tied them in, there would definitely be plans.

In order to protect themselves, they locked the wooden bolt inside the wooden door.

That is to say, if someone comes in from outside, unless the wooden door is damaged, it is impossible to enter the secret room with the door bolt intact.

However, when he was rescued the next day, Duan Zhongxin was killed.

Why?

There were only three people in the room. Both Yu Huihui and Tang Muqi said that they didn't kill anyone, so the other party must have killed Duan Zhongxin.

Chen Yan frowned!

This secret room is not an ordinary secret room, but a double secret room.

Outside, there is wire wrapped around it.

There are wooden bolts inside to lock.

Chen Yan had seen this wooden bolt.

There are locks on both sides. Once the crossarm is locked, it cannot be opened from the outside without destroying the structure of the wooden door.

How the **** did the killer do all this.

Could it be that the murderer was really one of Yu Huihui and Tang Muqi?

Or, do both of them have a share?

This possibility is not impossible.

If the two of them join forces to kill Duan Zhongxin in the secret room, let someone they trust wrap the wooden door with iron wire, creating the illusion of murder in the secret room.

After that, it is not impossible to bite the other party and deliberately create ecstasy bombs.

...

Because there is no clear evidence to prove that Yu Huihui or Tang Muqi are the murderers, the two were not detained.

Soon after the case, the two returned to work in the hotel and the security team respectively.

However, they were asked not to leave Yinglu City, and to cooperate with detectives to investigate the progress of the case at any time.

Okay, come back to the hotel.

Chen Yan saw this Yu Huihui.

The other party knew that Chen Yan was here to investigate Duan Zhongxin's case, and there was no resistance, and they were very cooperative.

"Officer Chen," Yu Huihui's voice was very warm and trembling: "There is no need to investigate this matter, it must have been done by Tang Muqi."

"At that time, it was just the three of us in the house."

"Then when we woke up, Duan Zhongxin suggested that the door bolt be plugged in. Tang Muqi and I also checked, and there was absolutely no problem."

"And, when we were rescued the next day, the pegs were intact, which means that when we were unconscious for the second time, no one came in at all."

"I didn't kill Duan Zhongxin, so it can only be Tang Muqi."

...

In the security dormitory, Chen Yan also saw Tang Muqi.

"This police officer, let me tell you, this case doesn't need to be investigated at all, it's the person Yu Huihui killed."

"We locked the house with wooden bolts."

"When I was rescued the next day, the wooden bolt was intact. Did someone escape in?"

"It must be the woman who killed the person, didn't run!"

Leaving the security dormitory, Hu Xueying smiled bitterly: "Team Leader Chen, you saw it too."

"These two people are very sure that the other party killed Duan Zhongxin."

"However, the evidence at the scene shows that the two are unlikely to be the murderers..."

call……

He let out a long breath, and Chen Yan frowned.

In this case, to be honest, Chen Yan doesn't have any clues now.

The tone of the two's words was very certain, and their eyes were very magnanimous.

Both of them are very sure that the other party is the murderer.

"Am I guessing wrong?"

Are these two really not conspiring?

However, if the two did not conspire, the murderer... how did he do it.

Is it really like what Tang Muqi said, the other party drilled out of the ground.

impossible.

The floor of the factory building is cement, and the floor of the red brick house is red brick. ,

There are no signs of damage.

Sky, underground, walls, wooden doors...

Not only did Chen Yan study it carefully, even Hu Xueying, they searched almost every inch of the red brick house.

But nothing gained.

Therefore, Yu Huihui and Tang Muqi...

Chen Yan believes that there must be something wrong with these two!

It's just that Chen Yan has not found their flaws yet.
