Chapter 236 Sort out the dossier
After leaving the red brick house, Chen Yan knew why Hu Xueying was so haggard.
This case, the Yinglu City Criminal Police Team, has been investigating for nearly half a year. .
However, so far, there are still no clues.
The most important thing about killing in a secret room is to deduce the process of the murderer's murder, or how to do it.
【Ding! The task of the strongest police training system is released. 】
[Detect the murder case in the secret room, within five days, complete the task, reward parkour skills specialization, fail or overdue to cancel the task reward. 】
Parkour?
Chen Yan was slightly taken aback, this skill was new and indeed very useful.
When handling a case, it is inevitable that there will be a chase.
Although Chen Yan relies on the gene lock rewarded by the system, his physical fitness is no longer what it used to be.
However, if you master this skill, you will get twice the result with half the effort.
...
For the Yinglu City Criminal Police 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 for Tongda Transportation Company as a truck driver and was mainly responsible for delivering express delivery.
According to the autopsy report, the direct cause of Duan Zhongxin's death was severe blunt impact on the back of the head.
Ultimately, death resulted from intracranial hemorrhage.
According to the analysis of the situation at the scene of the crime, the murderer beat Duan Zhongxin to death with bricks on the ground.
However, in addition to the fatal blunt trauma, Duan Zhongxin also had a small wound on the back of his head.
This wound was not formed by a brick blow.
It should be a hammer blow.
The dossier records the conjectures of the investigators at that time.
Duan Zhongxin should have been knocked on the back of the head with a hammer first, causing a coma, and then transported to the red brick room of the warehouse.
Not only that, but the detective in charge of the autopsy also detected the residue of ether in Duan Zhongxin's body.
This shows that the murderer also stunned Duan Zhongxin with ether.
This is a little strange.
Since Duan Zhongxin was knocked out with 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 dead, there were two survivors at the scene.
Survivor No. 1, Yu Huihui, female, from Shanggang Village, 33 years old, worked as a cashier in the Haozailai restaurant in the logistics park.
this woman...
How should I put it, although she is 33 years old, this Yu Huihui looks very young.
The photos in the dossier 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 obsequiousness and looks very charming.
Although the eyes are not big, they seem to have hooks.
Even in photographs, there is an illusion that the eyes can speak.
Such a woman...
hehe.
Survivor No. 2, Tang Muqi, male, 56 years old, a laid-off villager, 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, nothing special about him.
The files are organized in great detail.
Moreover, when the detectives at that time broke through the red brick house, there was also a video shooting, but because of the light, the video was blurry.
The specific time of the incident was 9:28 am on July 28.
The detective who was out at the time was called Li Tongyun. After hearing the cry of help in the red brick house, he immediately found pliers and cut the iron 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 splatters on Yu Huihui and Tang Muqi,
The house was so dark that the dead might not even be found.
After that, Li Tongyun immediately reported to his superiors.
On the same day, the Yinglu City Police Department began interrogating Huihui and Tang Muqi.
According to the confessions of Yu Huihui and Tang Muqi, both of them were stunned and knocked out on the night of the 27th.
Yu Huihui got off work around 11:30 p.m. on the 27th, and on the way home, she was controlled from behind by someone, and she was stunned with ether.
This should be true, because the detectives detected ether residues from Yu Huihui's body.
On the night of the 27th, Tang Muqi was in charge of patrolling the factory building in the neighboring area. According to his recollection, he was beaten with a sap during the patrol, and then also stunned with ether.
When he wakes up again, he will be in the dark.
At that time, not only Yu Huihui and Tang Muqi, but also the deceased Duan Zhongxin woke up from a coma.
The three of them fumbled for the exit together, but after no results, they passed out again because of exhaustion, fear, and the influence of the residual substance of the drug.
When he woke up, he was awakened by a knock on the door.
After that, it was Li Tongyun who broke the wire outside and rescued them.
However, at this time, Duan Zhongxin was already dead.
Afterwards, 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 was the murderer.
After the incident, the crime scene was not destroyed.
According to the later investigation records, after Duan Zhongxin was killed, the red brick house was the first crime scene from the traces of blood spurting, the direction and the autopsy report.
However, there were no fingerprints of Yu Huihui or Tang Muqi on the brick used for murder.
Both of them had blood sprayed from the same direction.
This means that when Duan Zhongxin was killed, the two should still be in a coma.
Moreover, they are all in the direction facing the wooden door.
Because the spurts of blood on the two of them were continuous.
This means that there must be 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 that time, and there could be no 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 were unable to open it.
And Duan Zhongxin suggested that since someone tied them in, there must be something for them.
In order to protect themselves, they locked the wooden bolts inside the wooden door.
In other words, if someone came in from outside, unless the wooden door was damaged, it would be 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, and both Yu Huihui and Tang Muqi said that they did not kill anyone, so it must be the other party who killed Duan Zhongxin.
Chen Yan frowned!
This secret room is not an ordinary secret room, but a double secret room.
Outside, there is wire winding.
There is a wooden bolt inside to lock it.
Chen Yan has seen this peg.
There are locks on both sides. Once the cross-arm is locked, it cannot be opened from the outside without destroying the structure of the wooden door.
How on earth did the murderer do all this.
Could it be that the murderer is really one of Yu Huihui and Tang Muqi?
Or, do both of them have a share?
This possibility is not impossible.
If the two teamed up to kill Duan Zhongxin in the secret room, and then asked someone trustworthy to wrap the wooden door with wire, creating the illusion of a murder in the secret room.
After that, it is not impossible to bite the opponent back and deliberately create a ecstasy bomb.
...
Because there was no clear evidence that Yu Huihui or Tang Muqi was the murderer, they were not detained.
Not long after the case happened, 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 the detectives to investigate the progress of the case at any time.
Come to the hotel again.
Chen Yan saw this Yu Huihui.
The other party knew that Chen Yan was here to investigate Duan Zhongxin's case, so he didn't have any resistance and cooperated very well.
Officer Chen, Yu Huihui's voice was very warm and waxy, with a hint of trill: There is no need to investigate this matter, Tang Muqi must have done it.
At that time, there were only three of us in the house.
Then when we woke up, Duan Zhongxin proposed to put the bolt on. Tang Muqi and I also checked it. There is absolutely no problem.
Moreover, when we were rescued the next day, the peg was intact, which means that when we were unconscious for the second time, no one came in at all from outside.
I didn't kill Duan Zhongxin, so Tang Muqi could only kill him.
...
In the security dormitory, Chen Yan also met Tang Muqi.
This police officer, let me tell you, there is no need to investigate this case at all. Yu Huihui killed the person.
In the house we locked it with a wooden bolt.
When I was rescued the next day, the peg was intact. Could it be that someone sneaked in?
That woman must have killed him, he didn't run away!
After leaving the security dormitory, Hu Xueying smiled wryly: Team Leader Chen, you also saw it.
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 murderer...
call……
Letting out a long breath of foul air, Chen Yan frowned.
To be honest, Chen Yan has no clue about this case.
The tone of the two people's words was very positive, and their eyes were also very frank.
Both of them are very sure that the other party is the murderer.
Did I guess wrong?
The two really didn't conspire?
However, if the two hadn't conspired, the murderer... how did he do it.
Is it really like what Tang Muqi said, the other party came out of the ground.
impossible.
The floor of the factory building is made of cement, while the floor of the red brick building is made of red brick. ,
No signs of damage.
The sky, the ground, the wall, the wooden door...
Not only Chen Yan studied it carefully, even Hu Xueying, they searched almost every inch of the red brick house.
But nothing was gained.
Therefore, Yu Huihui and Tang Muqi...
Chen Yan thought that there must be something wrong with these two!
It's just that Chen Yan hasn't discovered their flaws yet.
