Chapter 140: Is Human Nature Good or Evil?
The area of the crime scene.
Chen Yan, Qin Chuan, Huang Guojun, and the task force were basically all present.
The outermost layer of the smoke exhaust hole is a protective cover to prevent cold wind from pouring back and waterproof.
After the protective cover is taken off, it is an iron piece for one-way locking.
Everyone look here. Chen Yan pointed to the one-way locking iron plate: Everyone knows the function of the locking iron plate.
Chen Yan raised the iron sheet with a little force with his fingers: Everyone, look, there is a faint half-moon-shaped scratch on the surface of the iron sheet.
Qin Chuan stepped forward to check in person.
Scratch marks are very faint and barely noticeable.
If it weren't for Chen Yan's reminder, Qin Chuan would have hardly noticed it if he watched carefully.
Huang Guojun also stepped forward to take a look, and asked suspiciously: Zu Chen, this scratch...was left by the murderer?
But how did he let the exhaust gas from the water heater flow back?
Huang Guojun completely blocked the iron piece: If the iron piece is completely blocked, oxygen-containing air cannot enter, and the water heater will automatically turn off.
Chen Yan nodded: That's true, but what if the murderer can make the iron plate open and close in one direction?
Look, everyone, under normal circumstances, this piece of iron can be pushed away by the exhaust gas from the water heater.
However, if the weight of the iron sheet is increased, such as this...
Chen Yan took out a small semi-circular black block and motioned for everyone to see it.
magnet?
Liyang was surprised.
Yes, it's a magnet!
After Chen Yan attached the magnet to the iron sheet: Liyang, go to the room, turn on the hot water faucet, and let the water heater work.
At the same time, close the doors and windows, and use instruments to detect the concentration of carbon monoxide in the room.
...
After a while.
The water heater starts.
The iron piece, which should normally be opened smoothly, has increased in weight due to the adhesion of the magnet, and now it cannot be pushed open by the exhaust gas exhausted by the water heater.
Chen Yan took off the magnet, and the weight of the iron piece was reduced, and it was suddenly pushed away by the exhaust gas.
Chen Yan knocked the magnet against the wall, took off half of it, and put the iron piece on it again.
At this time, although the iron sheet can still be pushed back by the exhaust gas again, the pushing range is obviously much smaller.
Probably only one-fifth of the original level.
In a quarter of an hour.
Liyang ran out of the room, and looked at Chen Yan with surprise on his face: Group Chen, the concentration of carbon monoxide in the room is rising!
The root cause of carbon monoxide poisoning has been found!
The murderer used a very simple device to achieve the intended purpose.
A small piece of magnet.
The opening and closing degree of the one-way iron sheet becomes smaller, which can not only block the exhaust gas and discharge it into the room, but also ensure that a certain amount of aerobic air enters the water heater.
Leave the water heater running all the time.
wonderful!
If it weren't for the scratches left by the magnets on the one-way locking iron plate, Chen Yan would never have thought of this.
But don't underestimate this.
The direct cause of death of the deceased was carbon monoxide poisoning.
But how did the four dead people get poisoned?
Regardless of whether the murderer can be caught or the case can be solved, these are puzzles that must be solved.
Even if the murderer is caught, if the other party doesn't tell him, the investigators will not be able to figure out what the murderer did, and you will have no way to decide on him.
Why?
The immediate cause of death should be carbon monoxide poisoning.
To put it simply, the murderer broadcast live in the WeChat group later.
It was to change the clothes of the corpses, to arrange the shapes, to arrange the last supper, and finally to make four corpses into dolls.
In fact, it is an insult to the corpse.
According to the time of the video and the time of the deceased's death.
The person who plays with the dead body and starts the doll live broadcast is not necessarily the murderer.
Because, the cause of death of the deceased was carbon monoxide poisoning.
Poisoning is the root cause.
The others are the clues of the detectives, the clues to find the murderer.
And now, the most important link in the chain of evidence has been cracked.
Return to Calabash City Detective Team.
It was 6 pm on the 12th.
Qi Yuansheng brought further clues.
All 32 group members who watched the video were contacted.
Among them, one happened to be in Hulu City.
interrogation room.
I really didn't know it was a corpse...
In the monitoring room, Qi Yuansheng was introducing Chen Yan and Qin Chuan.
This person's name is Yang Qi, 24 years old, and he's a delivery man from Hungry or Hungry.
I liked dolls since I was a child. Two years ago, when I was watching the live broadcast at night, I saw a video of Zhao Mingwei playing with dolls. I am a fan of Zhao Mingwei.
Two years ago, I joined the WeChat group organized by Zhao Mingwei.
Ask about the interior.
We are just looking for you to understand the situation. As for the live broadcaster, have you seen him in person before?
Really not, Chen Qi cried, his body trembling slightly: We are a group with common hobbies.
Everyone usually shares their dolls in the group.
We haven't met each other, and during the live broadcast, we all wear masks and don't show our faces.
Ask him, why didn't he show his face in the live broadcast?
In the monitoring room, Chen Yan instructed the detectives in the interrogation room through the wireless microphone.
There are very few people who don't show their faces live.
Why Live?
Don't you just want to be famous?
Don't show your face, what's the live broadcast?
Of course, some podcasters create personalities that are private, but Zhao Mingwei just plays with dolls, so that's not the case.
Why don't you show your face in the live broadcast?
As a result, as soon as the detective finished asking, Chen Qi's eyes dodged a little, and he hesitated in speaking.
This this……
The detective who inquired was also a veteran of Jianghu, so he naturally saw that something was wrong with Chen Qi.
Chen Qi, I think you need to understand a little bit.
The live broadcast you watched on August 9th was not an ordinary doll changing clothes, but a major live broadcast murder with particularly bad influence!
As a witness, you didn't discover it, didn't stop it, and were even willing to watch!
Chen Qi, until now, are you still hiding it?
No, no! Chen Qi was obviously frightened.
I'm not hiding it, it's just... I'm just not ashamed to say...
half an hour later.
Chen Qi was all down.
how to say.
This group of them...
Not very serious.
The reason why there are fewer people in this group is because they share similar tastes.
When we were live broadcasting, sometimes we would interact with dolls...
You know, I'm single...
Many of the dolls we buy are physical dolls that emulate human beings...
Besides, the group owner is more fun.
That woman that day, the young one...
The group leader gave medicine before and showed us...
So, we didn't pay attention that day, thinking that the group leader came to play that game again...
By the way, he also messed with his brother...
His brother?
The detective who questioned Chen Qi's expression changed from surprise to shock.
It's his brother, you don't know, his brother doesn't look like a man, he looks very beautiful...
However, that one doesn't seem to be his own brother. During the voice chat, I heard that he seemed to be adopted by his parents, just like a dog raised by his family...
By the way, a few months ago, the group leader once drank too much and said that his girlfriend turned out to be his sister-in-law, and that he played with two sister-in-laws or something.
However, none of us believed it. He should be bragging...
Monitoring room.
Everyone was silent for a while.
Both Qin Chuan and Huang Guojun are old detectives.
The strange things I have seen, there are too many strange people.
However, this kind of today is really the first contact.
Hearing this, he couldn't help being a little silent.
Although Chen Yan has been in the police for a short time, he has experienced many cases.
For human nature, Chen Yan's understanding is not necessarily lower than that of Qin Chuan or Huang Guojun.
Why did Liang Wenyuan, the murderer in the case of dismembering his wife and killing his wife, commit murder?
Professor Yang Chenghan in the Scarlet Cross case, why did he kill someone?
It's just three words, it's hard to understand!
Good guys can sometimes be bad guys.
Bad guys, sometimes not necessarily just bad guys.
Let alone who killed Zhao Mingwei.
As far as what Zhao Mingwei did, it might be difficult to associate with good people.
Is human nature good or evil?
At this moment, Chen Yan suddenly thought of Zhao Danyang.
That man with narrow eyes, slender eyebrows, and a feminine face.
Suddenly, Chen Yan understood why he was hysterical and why he was crying bitterly.
On the one hand, it is the grace of nurturing, and on the other hand, it is the bullying of more than 20 years.
How to do?
However, no matter what to do, Chen Yan now wants to meet this Zhao Danyang again.
He had to verify some of the things Chen Qi said.
Although, Chen Yan knew that his departure would heal Zhao Danyang's scar again.
However, the case is still to be solved.
In particular, what Chen Qi mentioned was the information that Zhao Mingwei once mentioned when he was drunk.
Ding Suxi...
Does it really have something to do with Zhao Danyang?
Also, the two sisters-in-law... what's going on?
