Chapter 236 Sorting Out the Files

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, there is still no clue so far.

The most important thing about a closed room murder is to infer the murderer's process, or how to do the closed room murder.

[Ding! The strongest police training system task is released. ]

[Solve the closed room murder case, the deadline is five days, complete the task, and reward the parkour skill expertise, failure or overdue to cancel the task reward. ]

Parkour?

Chen Yan was slightly startled, this skill is fresh, and it is indeed very useful.

When handling a case, it is inevitable to stage a chase.

Although Chen Yan's physical fitness has long been different from the past with the gene lock rewarded by the system.

However, if you master this skill, it will definitely be 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 delivered to Chen Yan.

The deceased, Duan Zhongxin, male, 41 years old, from Linshui Village, Panshan Town, Yinglu City, worked at Tongda Transport Company as a truck driver before being killed, mainly responsible for delivering express delivery.

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

Eventually, he died of intracranial hemorrhage.

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

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

This wound was not caused by a brick.

It should be a hammer.

The file records the speculation of the case handlers at the time.

Duan Zhongxin should have been hit on the back of the head with a hammer, causing coma, and then transported to the red brick house in the warehouse.

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

This shows that the murderer had also used ether to knock Duan Zhongxin unconscious.

This is a bit strange.

Since Duan Zhongxin had been knocked unconscious by the hammer, why did the murderer use ether?

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

Or was 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, worked as a cashier at Hao Zai Lai Restaurant in the logistics park.

This woman...

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

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

The woman has a delicate face and 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 her eyes are not big, they seem to have hooks.

Even in the photo, it seems that there is an illusion that the eyes can speak.

Such a woman...

Haha.

Survivor No. 2, Tang Muqi, male, 56 years old, from Xiagang Village, works as a security guard in the logistics park, and is a fellow villager of the reporter Zhang Baoshan.

This man has an ordinary face and nothing special.

The files were organized in great detail.

Moreover, when the detectives broke into the red brick house, they also filmed a video, but the video was blurry due to the light.

The specific time of the crime was 9:28 am on July 28.

The detective who responded to the call was Li Tongyun. After hearing the cry for help from the red brick house, he immediately found 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 were not for the blood splatter on Yu Huihui and Tang Muqi, and the house was dark, the deceased might not have been found.

After that, Li Tongyun immediately reported to his superiors.

On the same day, the Yinglu City Detective Team interrogated Yu Huihui and Tang Muqi.

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

Yu Huihui got off work at around 11:30 pm on the 27th, and on the way home, she was controlled from behind and knocked out with ether.

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

Tang Muqi was responsible for patrolling the factory in the next area on the night of the 27th. According to his recollection, he was hit by a club during the patrol and then knocked out with ether.

When he woke up again, he was already in darkness.

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

The three of them groped for the exit together, but after failing, they fainted again due to fatigue, fear, and the residual substances of the drug.

When they woke up, they were awakened by the knock on the door.

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

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

Afterwards, Yu Huihui and Tang Muqi each identified the other as the murderer.

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

After the crime, the crime scene was not destroyed.

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

However, there were no fingerprints of Yu Huihui or Tang Muqi on the bricks used for the murder.

Both of them had blood sprays in the same direction.

This means that when Duan Zhongxin was killed, they should have been in a coma.

Moreover, they were all in the direction of the wooden door.

Because the blood sprays on the two people were continuous.

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

Or 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 not be a fourth person.

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

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

Duan Zhongxin suggested that since someone tied them in, they must have a purpose.

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

In other words, if someone came in from outside, it would be impossible to enter the secret room with the bolt intact unless the wooden door was damaged.

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

Why?

There were only three people in the room. Both Yu Huihui and Tang Muqi said that they did not 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.

There is iron wire wrapped around the outside.

There is a wooden bolt locked inside.

Chen Yan has seen this wooden bolt.

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

How did the murderer do all this?

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

Or, are both of them involved?

This possibility is not impossible.

If the two of them teamed up to kill Duan Zhongxin in the secret room, and then let a trusted person wrap the wooden door with iron wire to create the illusion of murder in the secret room.

After that, it is not impossible to bite the other party and deliberately make a soul bomb.

...

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

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

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

Good to come to the hotel again.

Chen Yan met this Yu Huihui.

The other party knew that Chen Yan was here to investigate Duan Zhongxin's case, and there was no resistance, and he cooperated very well.

"Officer Chen," Yu Huihui's voice was very warm and trembling: "There is no need to investigate this matter at all, it must be Tang Muqi who did it."

"There were only three of us in the house at that time."

"Then when we woke up, Duan Zhongxin suggested to plug the door bolt, and Tang Muqi and I also checked it, and there was absolutely no problem."

"Moreover, when we were rescued the next day, the wooden bolt was intact, which means that when we were unconscious for the second time, no one came in from outside."

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

...

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

"Officer, I tell you, there is no need to investigate this case. Yu Huihui killed the person."

"We locked the house with a wooden bolt."

"When we were rescued the next day, the wooden bolt was intact. Could someone have sneaked in?"

"It must be that woman who killed the person. She didn't run away!"

After 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."

"But the evidence at the scene shows that the two are unlikely to be the murderer..."

Huh...

After a long breath of turbid air, Chen Yan frowned.

To be honest, Chen Yan has no clue about this case now.

The tone of the two people's words is very certain, and their eyes are also very frank.

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

"Am I wrong?"

Did these two people really not conspire?

But if the two did not conspire, how did the murderer... do it?

Is it really like Tang Muqi said that the other party came out from the ground?

It's impossible.

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

There is no sign of damage.

The sky, the ground, the walls, the wooden doors...

Not only Chen Yan has studied it carefully, even Hu Xueying, they have checked almost every inch of the red brick house.

But there is no gain at all.

So, Yu Huihui and Tang Muqi...

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

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