Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 702: Clues from on-site exploration 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'm out there all year round."

Chen Gang's family situation is also good. He is the director of an information system maintenance company. In recent years, his 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 the year.

"We were college classmates and got married after graduation. Because I was busy at work, she stopped working later."

"About four years."

"Don't you want a child?"

What Xu Qianqian didn't know was that 10 out of 9 times when Wang Chuanzhi mentioned socializing and dining, she went to see Zhang Cuilian.

Even once, Zhang Cuilian took Wang Chuanzhi home after Chen Gang was drunk.

You can make money if you are willing to endure hardship.

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.

He and Chen Gang were on the bed in the master bedroom, while Chen Gang was sleeping drunk next to them, and the two of them had sex for half a night.

During the current criminal investigation period, mobile phones must be kept by the police as evidence involved.

"Due to my health, I have never wanted to undergo in vitro fertilization. I have been undergoing in vitro fertilization for the past two years..."

But these two people who seem to love their families are actually male thieves and female prostitutes behind their backs.

In the eyes of Xu Qianqian, wife of the deceased Wang Chuanzhi, Wang Chuanzhi was a family-oriented person.

Since the two met a year ago, they have been seeing each other at least 3 to 4 times a week.

Moreover, Zhang Cuilian even recorded the video and saved it on her mobile phone.

What Chen Gang didn't know was that even when he wasn't on a business trip, Zhang Cuilian was still trying to make ends meet with Wang Chuanzhi.

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.

It's good for her and good for the kids.

Of course, Zhang Hui did not tell the husband and wife about these things.

Regarding the family situation of the two of them, Zhang Hui had almost figured it out in less than half a day.

In the eyes of the deceased Zhang Cuilian's husband, Chen Gang, Zhang Cuilian was also a considerate, gentle and virtuous wife.

The chat history is even more unsightly.

There are videos on the phone of two people fighting.

As for what's inside, whether they can discover it or not is their own business.

Criminal Investigation Detachment No. 1 Conference Room, twelve o'clock in the evening.

The criminal investigation detachment at midnight had no New Year atmosphere at all.

Everyone was busy running around in circles.

It seems 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 a.m., it was confirmed that there were two deceased persons in a local Volkswagen sedan with license plate number 89345."

"Forensic doctor, please report on 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 bodies without consulting the families. The autopsy mentioned here is not a superficial examination, just to find out the cause of death.

Instead, the body must be dissected, three chambers opened, and if necessary, even toxicology testing must be performed.

Wang Changjiang coughed twice as he was accustomed to and began to introduce the corpse examination situation.

"The time of death of both deceased persons was around 17 a.m. on the 3th."

"The cause of death was carbon monoxide poisoning."

"The female victim showed no signs of being violated. Judging from the clues obtained from the autopsy, there are not many."

The process of autopsy performed by a forensic doctor is relatively complicated. Height, weight, hair volume, age, etc. are all important contents of the autopsy.

This may even include skin color, whether there are old traumas, 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.

Another example is the female deceased Zhang Cuilian. She had multiple abortions and her uterine wall was very thin, so her chances of becoming pregnant 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 conducted to confirm the time and cause of death of the deceased.

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 quite 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 medical examiner has confirmed that the direct cause of death of the two deceased persons 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 went to the vehicle inspection office and commissioned them to conduct an exhaust gas test on the vehicle."

Lu Chuan controlled the projector and what appeared on it was a test report.

"This is the vehicle inspection company commissioned by the vehicle inspection agency to conduct an exhaust gas test on this black Volkswagen sedan."

"We focused on testing the carbon monoxide concentration in the vehicle when the vehicle was started."

"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, which 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. "

"In either case, from the perspective of current investigation, the carbon monoxide gas in which the deceased died did not come from vehicle exhaust combustion."

"After reaching this conclusion, we conducted a detailed inspection of the vehicle again."

Lu Chuan continued to play the projection.

It's five photos.

"These five photos show the door handles of the four doors of the vehicle and the open positions of the trunk."

"We detected fingerprints on the driver's door handle and both rear seats."

What appears on the projection are many fingerprint photos.
