"I don’t know Wang Chuanzhi, I’ve never heard of this name."
In response to Zhang Hui’s question, Chen Gang answered cooperatively.
"I maintain the information systems for the public security, so I travel a lot, practically all year round I’m out there running around."
Chen Gang’s family situation is also quite good. He’s a director at an information system maintenance company, and in recent years, their company has won some bids to maintain certain information systems for the public security bureau.
It’s precisely because of this that Chen Gang bought a house in the family area of the public security bureau.
Due to the nature of his job, he travels a lot, and he’s not at home for about half of the year.
"The two of us were college classmates. We got married after graduation, and since I’m quite busy with work, she later stopped working."
"It’s been about four years now."
"Haven’t you had children?"
"Because of my health, we haven’t been able to, and these past two years we’re trying in vitro fertilization..."
During the questioning of Chen Gang, Zhang Hui and the others found that the couple’s relationship seemed to be quite good.
At least when Chen Gang was at home, the couple got along well.
Within half a day, Zhang Hui had almost uncovered the couple’s family situation.
In Xu Qianqian, the wife of the deceased Wang Chuanzhi’s eyes, Wang Chuanzhi was a family-oriented man.
He treated her well and was good to the children.
He was willing to endure hardships and could earn money.
In Chen Gang’s eyes, the deceased Zhang Cuilian was also an understanding, gentle, and virtuous wife.
But these two seemingly family-loving people were secretly full of immoral conduct.
What Chen Gang didn’t know was that even when he wasn’t on a business trip, Zhang Cuilian was having an affair with Wang Chuanzhi.
She even once brought Wang Chuanzhi home after Chen Gang got drunk.
Right on the bed in the master bedroom with Chen Gang, the two engaged in an affair for half the night while Chen Gang was fast asleep in a drunken stupor beside them.
Moreover, Zhang Cuilian even recorded videos, stored on her phone.
What Xu Qianqian didn’t know was that nine out of ten times when Wang Chuanzhi said he was out socializing and dining, he was meeting with Zhang Cuilian.
Ever since they met a year ago, they had been meeting at least three to four times a week.
Their phones were filled with videos of their exploits.
Their chat records were even more outrageous.
Of course, Zhang Hui didn’t disclose these matters to either of the husbands and wives.
As it was still the criminal case-solving period, the phones, as involved evidence, had to be kept by the police.
Of course, since phones are relatively valuable property, they would be returned to the deceased’s families after the case is cracked.
Regarding what might be found within, that was their own business.
Criminal Investigation Team Meeting Room No. 1, midnight.
The Criminal Investigation Team at midnight didn’t have the slightest New Year atmosphere.
Everyone was busy running in circles.
As the information was summarized piece by piece, it seemed easy, but in reality, it was all the detectives running on foot to obtain it.
The first case analysis meeting was taking place.
Qin Yong chaired the meeting as usual.
"At 9:28 this morning, Lu Chuan, the head of the Crime Scene Investigation Office, discovered a suspected victim at the entrance of the City Public Security Bureau’s family area."
"At 9:42 a.m., it was confirmed that there were two deceased individuals inside a local Volkswagen sedan with license plate number 89345."
"Forensic Doctor, please report on the autopsy findings."
By procedure, not all bodies need an autopsy, like unexpected deaths or illnesses, which don’t require an autopsy.
However, most criminal cases’ bodies do undergo autopsy, and it’s not necessary to seek the family’s consent.
The autopsy mentioned here doesn’t merely involve surface examination to determine the cause of death.
It means dissecting the body, opening the three cavities, and when necessary, conducting toxicology tests.
Wang Changjiang habitually coughed twice and began to explain the autopsy findings.
"Both deceased individuals died around 3 a.m. on the 17th."
"The cause of death was carbon monoxide poisoning."
"The female victim showed no signs of assault, and there weren’t many clues from the autopsy."
The forensic autopsy process is quite complex, including height, weight, hair volume, age, among other important content.
Even things like skin color, whether there are old wounds, or other unique characteristics.
And both deceased did have some characteristics that were different from ordinary people.
For instance, the male victim Wang Chuanzhi had an old fracture in his left leg, dating back about 3 to 5 years.
For the female victim Zhang Cuilian, she had several abortion experiences, with a very thin uterine wall and almost no chance of pregnancy.
However, these weren’t the key points for solving the case.
Wang Changjiang’s report had all these details explained.
He didn’t emphasize these specifics in the meeting.
But from a judicial perspective, performing an autopsy to confirm the deceased’s time and cause of death was a necessary procedure.
"How’s the Crime Scene Investigation going?"
Qin Yong looked at Lu Chuan.
Lu Chuan, after returning, hadn’t stopped for a moment and was continuously performing crime scene analysis.
"The clues we’ve got here are quite scattered."
Lu Chuan’s leads were many but not systematic, so they could only be reported one by one.
"First, let’s talk about the cause of death."
"The Forensic Doctor here has already confirmed that the direct cause of death for the deceased is carbon monoxide poisoning."
"But we’ve conducted a careful examination of the vehicle. Although the black Volkswagen sedan driven by the deceased is quite old, its chassis is relatively well-sealed."
"This afternoon, Yang Lin specifically went to the vehicle inspection station and commissioned them to carry out an exhaust analysis of the vehicle."
Lu Chuan operated the projector to display a test report.
"This is the exhaust analysis conducted by the vehicle inspection company commissioned by the inspection station on this black Volkswagen sedan."
"We focused on testing the carbon monoxide concentration inside the vehicle when it was running."
"It was essentially unchanged from when the vehicle was off."
"I even personally sat in the car and couldn’t smell any gasoline combustion odor at all."
"Additionally, considering there’s still half of the fuel in the car, but the vehicle was already off when we found it, this indicates that either the deceased turned off the car before dying, or the killer staged a carbon monoxide poisoning scene and then turned off the car."
"In any case, from the Crime Scene Investigation perspective, the carbon monoxide that the deceased succumbed to wasn’t coming from the vehicle’s exhaust fumes."
"With this conclusion, we went back to thoroughly examine the vehicle again."
Lu Chuan continued the slideshow presentation.
There were five photographs.
"These five photos show the opening positions of the car’s four door handles and the trunk."
"We detected fingerprints on the driver’s door handle and on the two rear doors."
The projection showed numerous fingerprint photographs.
