Chapter 200 Cyanide poisoning
Entering the scene, Chen Yan immediately began to survey the scene.
【Ding! The task of the strongest police training system is released. 】
[To solve the cyanide poisoning case, there is a deadline of two days. Complete the task and reward skill rock climbing technology specialization. If you fail or exceed the deadline, the task reward will be cancelled. 】
Climbing specialization?
The last reward was Swimming Skill Specialization.
This time it's rock climbing skills.
Moreover, Chen Yan discovered that his own system, except for the first activation.
Every subsequent activation will only be activated again when a homicide is encountered, and the task will be issued.
As for other cases, the system did not give task prompts.
For example, in this theft case, the front and the system were all calm.
Until now, when a homicide occurred, the task was not released.
Putting down his thoughts, Chen Yan immediately activated the olfactory gene lock and the vision gene lock.
Li Yun introduced to Chen Yan the information he had obtained so far: The identities of the four deceased have been preliminarily confirmed.
Decedent No. 1, Wang Tianzhi, male, 36 years old, from Danshi, married.
Decedent No. 2, Yu Lingfang, female, 32 years old, from Hulu City, married.
According to the current information, Wang Tianzhi and Yu Lingfang are husband and wife.
Decedent No. 3, Zhang Chuanmin, male, 40 years old, from Danshi, deaf-mute, married.
Dead No. 4, Yu Linghui, female, 32 years old, from Hulu City, dwarfism patient, married.
Dead No. 3 and No. 4 are husband and wife.
At the scene of the crime, four people sat around the dining table.
The detectives numbered the four deceased in clockwise order.
The four people, Wang Tianzhi, the deceased No. 1, were tilted under the seat, and the chair was lying on the ground, and their hands were facing the direction of the door, ruthlessly pawing at the cracks in the floor.
There is blood seeping through the nails.
The complexion is pale, and the subcutaneous mucous membrane is red.
A more obvious reaction to cyanide poisoning.
The deceased No. 2 was slumped on the chair, without any reaction of struggling, his legs were straightened, and his eyes were opened and closed.
The deceased No. 3 was under the table. He probably got off the chair and climbed about one meter away.
On the dining table, the tableware of the deceased No. 3 fell on the ground and was smashed into pieces.
His body was stained with hot pot soup, and there were broken porcelain bowls on the ground.
Dead person No. 4 was smaller in stature, also sitting on a chair with his hands folded and his back leaning against the seat.
According to the visual estimation, the height is only about one meter, the body shape on the chair, the calf is hanging in the air, and the face is flush with the table.
The skins of all four were bright red.
The signs of hyperemia in the subcutaneous tissue are very obvious.
Chen Yan sniffed lightly.
On the spot, there is a faint taste of bitter almonds.
The deceased should have died from cyanide poisoning.
Cyanide, lethal in very small amounts.
Cyanide the size of a grain of rice, about three to five grams, can kill an adult quickly.
The lethal principle of this poison is actually similar to carbon monoxide poisoning.
However, the speed of death after poisoning is faster, and rescue is more difficult.
As for the smell of cyanide, the so-called bitter almond smell, not everyone's nose can smell it.
For example, even if you put a bitter almond in front of you, some people may not be able to smell it.
However, for Chen Yan to describe this smell as the smell of swimming pool water, it might be more appropriate.
How did the landlord find out about the dead man?
Chen Yan knelt down and carefully checked the condition of each deceased.
The landlord has been back to his hometown in Tieshi for the past two days, and he only came back last night.
Li Yun introduced the situation on the side.
It turned out that after the landlord came back last night, he heard from the street office that the police had been investigating the dwarfs for the past two days, and they came to greet the resident in the morning.
As a result, after knocking on the door for a long time, the people inside did not open the door.
I called and only heard the ringing of the phone inside, but no one answered. The landlord realized that something might have happened.
Besides, the landlord was quite careful. He called the neighbors, opened the door together, and then called the police.
Chen Yan nodded.
The process is not complicated.
The landlord not only called neighbors, but also recorded video with his mobile phone.
Therefore, the entire site is very well preserved.
The cause of death of the four people has been determined, and the time of death is about 12 hours.
That is, last night, around 12 o'clock, he died.
...
Three hours later.
The conference room of the second detective team.
Chen Yan held the first case analysis meeting.
I have just reported to the Liancheng Criminal Police Team and the Provincial Criminal Police Team about the relevant situation.
According to the instructions of my superiors, I will still take over the relevant cases.
However, it was transferred to the serious crime team of the Provincial Criminal Police Brigade.
Captain Li, let everyone know about the on-site investigation.
Li Yun immediately stood up and saluted: Yes, Team Leader Chen.
At this time, Li Yun knew that Chen Yan's identity was no longer the captain of the grassroots detective team on the same level as him.
It's the leader of the Serious Case Team of the Liao Provincial Detective Brigade.
The title will naturally change.
Moreover, the four deaths occurred in his own jurisdiction, and Li Yun was the most stressed out of all of them.
Based on information provided by the landlord, the identities of the four deceased persons have been established.
The two couples, Yu Lingfang, the No. 2 deceased, and Yu Linghui, the No. 4 deceased, are biological sisters.
Dead No. 4, Yu Linghui, was a dwarfism patient.
The other two male deceased were fellow villagers.
Relevant basic information verification has been sent to the Dan City Criminal Police Team for coordination and investigation.
The four people died around 12 o'clock last night, and the cause of death was cyanide poisoning.
After preliminary inspection, it was found that cyanide was put into the hot pot ingredients and four people ate it, resulting in cyanide poisoning.
It took Li Yun ten minutes to report the basic situation of the deceased.
Next, I will make work arrangements.
First, after video comparison and the identification of the cleaners of the Emperor's Family Community, we can basically confirm these four people. That is, on the morning of the 25th, Hu Yuefei's home was stolen. A suspect in the theft.
Projected photo switching.
The left side is the basic information of the four people, and the right side is the photo of the four people's drug discovery scene.
We were at the residence of the four people and found the black tights they used to commit the crime.
Hoods, hydraulic pliers, lockpicking tools, and plans.
According to the landlord's statement, Zhang Chuanmin, the No. 3 deceased, worked in a lock-picking company.
These four people have been renting in his self-built house for five years.
Five years ago, Wang Tianzhi, Yu Lingfang and Yu Linghui rented together.
Four years ago, Wang Tianzhi introduced Yu Linghui to his fellow countryman, the deaf-mute Zhang Chuanmin, and the two got married.
All four of them came from other places to work in Liancheng.
Chen Yan pointed to the projected photo: Then here comes the problem.
Why did these four people who were supposed to live their lives steal and plan so carefully?
Second, Chen Yan switched the projection again: Everyone, look here.
On the projection screen was a planar photo of the crime scene of the deceased.
Everyone, pay attention to the placement of the tableware on the table.
Based on the location distribution of the deceased after death, it can be judged.
When four people were eating, dead No. 1 and dead No. 2 were next to each other, and dead No. 3 and dead No. 4 were next to each other.
However, the distance between deceased No. 1 and deceased No. 4 is a bit too large.
At this location, Chen Yan pointed to the location between Wang Tianzhi, the No. 1 deceased, and Yu Linghui, the No. 4 deceased: There should also be a set of tableware here.
That is to say, at the scene of the crime, there was a fifth person who ate together yesterday.
However, the tableware that this person was using at that time disappeared, and the chair he was sitting on was also put away.
So, it is very likely that this person is the murderer!
First, Chen Yan looked at Li Yun: Captain Li, you arrange someone to thoroughly check the surveillance video near the self-built house.
Simultaneously investigate the social relations of the four deceased.
Second, Chen Yan looked at Liu Qingshan: Captain Liu, although we were at the scene, we found some evidence of the theft by the four.
However, no stolen goods were found.
That means that either the four people hid the stolen goods after committing the theft, or they were transferred by the murderer.
In short, it is impossible to disappear out of thin air.
You cooperate with Captain Li and focus on investigating the trajectory of the four people's lives, the use of vehicles, or whether there is any other rental information.
...
After half an hour, all work arrangements are over.
Chen Yan called Zhang Chaoyang.
Chaoyang, come with me to Junfa Media Exhibition Company.
Junfa Media Exhibition?
Zhang Chaoyang was slightly taken aback, and didn't think of the name for a while.
Junfa Media Exhibition Company?
Captain Chen, what place is this, why does it sound familiar...
Of course it sounds familiar. This is the company Wu Kaiyue works for.
At the scene of the crime, Chen Yan not only discovered the existence of the fifth person.
It wasn't just the smell of cyanide that was found, either.
Not only were the tools used by the four of them discovered.
At the scene of the crime, Chen Yan even found a somewhat familiar smell.
It's just that the smell is very light.
It seems to belong to someone's personal belongings, as if it had appeared at the scene of the crime.
Not that the person has been there.
Of course, these clues, though not as evidence.
However, it can guide Chen Yan to solve the case.
Junfa Media Exhibition Company.
In Wu Kaiyue's office, Chen Yan and Zhang Chaoyang saw this well-dressed man with extraordinary temperament.
Regarding Wu Kaiyue, Chen Yan and Zhang Chaoyang didn't know much about him.
However, it depends on who you compare with.
For example, compared with Wu Kaiyue's wife Hu Yuefei, Chen Yan and the others may have more information.
After all, Wu Kaiyue's illegitimate son is already two years old.
However, Hu Yuefei didn't notice it at all.
What's more interesting is that the child and the child's mother lived in the house bought by Wu Kaiyue and Hu Yuefei.
What kind of simple character can a man who can let his mistress rent in the house he bought?
The point is, his wife doesn't know about it yet.
More importantly, it has been concealed for at least two years.
Hello, Mr. Wu, we meet again.
Chen Yan snorted slightly to confirm again.
At the scene where the four bandits died, there was indeed a smell belonging to Wu Kaiyue.
The truth, sometimes, is often right in front of your eyes.
Everything impossible is nothing but a fog that obscures the truth.
Once peeled off, it is clear at a glance whether it is a human or a ghost.
