Chapter 702: Clues of on-the-spot analysis
“I don’t know Wang Chuanzhi, and I have never heard of this name.”
Faced with Zhang Hui’s question, Chen Gang responded cooperatively.
“I do maintenance for the public security information system. I usually travel a lot and I am out all year round.”
Chen Gang’s family conditions are also good. He himself is an information system maintainer. In recent years, their company has won the bid to maintain certain information systems of the Public Security Bureau.
It is for this reason that Chen just bought a house in the Family Courtyard of the Public Security Bureau.
Due to the nature of his work, he travels a lot and is away from home for almost half of a year.
"We were college classmates and got married after graduation. Because I was busy at work, she stopped working."
"It took about four years."
“Don’t you want a child?”
"Due to my health, I have never wanted to have sex. I have been undergoing in vitro fertilization for the past two years..."
During the questioning of Chen Gang, Zhang Hui and others found that the relationship between the two of them as husband and wife should be relatively good.
At least when Chen Gang was at home, the relationship between the two of them was relatively good.
In less than half a day, Zhang Hui had almost figured out the family situation of the two of them.
In the eyes of Xu Qianqian, wife of the deceased Wang Chuanzhi, Wang Chuanzhi was a more family-oriented person.
It's good for her and good for the kids.
You can make money if you are willing to endure hardship.
In the eyes of Chen Gang, the husband of the deceased Zhang Cuilian, Zhang Cuilian was also a considerate, gentle and virtuous wife.
But two people who seem to love their families are actually male thieves and female prostitutes secretly.
What Chen Gang didn't know was that even when he was not on a business trip, Zhang Cuilian was still trying to make do with Wang Chuanzhi.
Even once, Zhang Cuilian took Wang Chuanzhi home after Chen Gang was drunk.
On the bed between him and Chen Gang in the master bedroom, while Chen Gang was drunk and sleeping next to him, the two of them stayed together for half the night.
And Zhang Cuilian even recorded the video and saved it on her mobile phone.
What Xu Qianqian didn’t know was that 9 out of 10 times Wang Chuanzhi mentioned socializing and dining, she went to see Zhang Cuilian.
Since the two met a year ago, they have been seeing each other at least 3 to 4 times a week.
There are videos on the phone of two people fighting.
The chat history is even more unsightly.
Of course, Zhang Hui did not tell the husband and wife of both parties about these things.
This is during the period of criminal investigation, and mobile phones must be kept by the police as evidence involved.
Of course, because the mobile phone is a relatively valuable property, it will be returned to the family of the deceased after the case is solved.
As for what's inside, whether they can discover it or not is their own business.
Conference Room No. 1 of the Criminal Investigation Detachment, twelve o'clock in the evening.
The criminal investigation detachment at midnight has no New Year atmosphere at all.
Everyone was busy running around in circles.
It may seem easy to put together the information one by one, but in fact, each detective ran out with his legs.
The first case analysis meeting is currently being held.
Qin Yong presided over the meeting as usual.
“At 9:28 this morning, Lu Chuan, director of the Investigation Office of the Criminal Investigation Detachment, found the suspected victim at the gate of the Family Courtyard of the Municipal Public Security Bureau.”
“At 9:42 am, the license plate was confirmed There were two deceased persons in the local Volkswagen car numbered 89345."
"Forensic doctor, please report the autopsy first."
Procedurally speaking, not all corpses require an autopsy. For example, accidental death or death due to illness do not require an autopsy.
But in most criminal cases, autopsies are performed on the bodies, and the family members do not have to be consulted. The autopsy mentioned here is not a superficial examination, just to find out the cause of death.
Instead, an autopsy must be performed on the corpse, three chambers must be opened, and if necessary, toxicological testing must even be conducted.
Wang Changjiang coughed twice as he was accustomed to and began to introduce the corpse examination situation.
"The time of death of both victims was around 3 a.m. on the 17th."
"The cause of death was carbon monoxide poisoning."
"The female victim showed no signs of being violated. So far, according to the autopsy, Judging from the clues obtained, there are not many. "
The process of forensic autopsy is relatively complicated. Height, weight, hair volume, age, etc. are all important contents of the autopsy.
Even including the depth of skin color, whether there are old trauma, or other specific characteristics.
And the two deceased people did have some characteristics that were different from ordinary people.
For example, the male deceased Wang Chuanzhi had an old fracture in his left leg for about 3 to 5 years.
For another example, the female deceased Zhang Cuilian had multiple abortions. Her uterine wall was very thin and her chances of pregnancy were basically non-existent.
However, these are not the key points in solving the case.
The report issued by Wang Changjiang has detailed explanations.
At this meeting, he did not emphasize it.
However, from a judicial perspective, an autopsy was performed and the time and cause of death of the deceased was confirmed.
This is a necessary process.
"How about the current survey here?"
Qin Yong looked at Lu Chuan.
After Lu Chuan came back, he was not idle for a moment and kept doing on-the-spot analysis.
“The clues on our side are relatively mixed.”
Lu Chuan has many clues, but they are not systematic and can only be reported one by one.
“Let’s talk about the cause of death of the deceased first.”
“The forensic doctor has confirmed that the direct cause of death of the two deceased was carbon monoxide poisoning.”
"But we carefully inspected the vehicle. Although the black Volkswagen sedan driven by the deceased was relatively old, the chassis of the vehicle was still relatively airtight."
"This afternoon, Yang Lin I went to the vehicle inspection office specifically and asked them to conduct an exhaust gas test on the vehicle.”
What appeared on Lu Chuan’s control projector was a test report.
“This is the vehicle inspection company entrusted by the vehicle inspection agency to conduct an exhaust gas test on this black Volkswagen sedan.”
“We focused on testing the vehicle’s emissions when it is started. The content of carbon monoxide concentration inside.”
“Basically there is no change from the state when the vehicle is turned off.”
“Even when I was riding in the car, I couldn’t smell the smell of burning gasoline at all.”
“In addition, There was still half of the fuel in the car, but the vehicle was already extinguished when we found it. This means that either the deceased's car was extinguished before death, or the car was extinguished after the murderer faked the scene of carbon monoxide poisoning."
< br>“In either case, from the perspective of the on-site investigation, the carbon monoxide gas in which the deceased died did not come from the combustion of vehicle exhaust.”
“After reaching this conclusion, we once again examined the vehicle A detailed inspection was carried out ”
Lu Chuan continued to play the projection.
It is five photos.
“These 5 photos are of the door handles of the four doors of the vehicle and the open position of the trunk.”
“Among them, we have the driver’s door handle and the two rear seats. Fingerprints were detected on every door.”
Many fingerprint photos appeared on the projection.
