Chapter 916

Rongyuan district.

Han Bin returns to the second floor underground again. In order to avoid hindering the site investigation, the onlookers have been dispersed.

The people of the technology department have already surveyed the scene and are packing up the toolbox. When Ma Xiwen sees Han Bin, he comes over, "team Han, the scene has been preliminarily surveyed."

"What do you find?"

Ma Xiwen replied, "the surroundings of the car are very clean. No suspicious objects are found. The ground is all concrete and there are no obvious traces. The crime scene should be in the car.

This is a great wall SUV with a wide body and enough space to commit crimes. No signs of moving the body were found. There were traces of ropes around the seat, but no ropes were found in the car.

At the same time, 46 cigarette butts of Yunyan were found in the car, and a lot of burning marks were also found. Blood and fingerprints were found at the scene, which need to be taken back for further identification.

In addition, the situation inside the car is more complicated. In order to better preserve the crime scene, we are going to take the car back to the Municipal Bureau for further investigation and testing. "

Han Bin asked, "did you find the dash cam?"

"The memory card of the dash cam has been removed. The mobile phone of the deceased was not found, but the driver's license and the driver's book were all there. It can be confirmed that it was the vehicle of the deceased. That's what we've seen so far. "

Han Bin nodded, "brother Ma, it's hard."

"Yes, we'll close the team first. I'll let you know when we have the further appraisal results."

"Good."

Zhao Ming tut tut said, "tut Tut, in such a large space of the car, 46 cigarette ends were found. The victim would not have been smoked to death."

Jiang Yang shakes his head, "you still think, I haven't heard of who will be smoked to death."

Zhao Ming said, "no fatal wound was found on him. How did he die?"

Jiang Yang said, "in my experience, it is very likely that the carbon monoxide content in the car is too high, causing the dead to suffocate."

In recent years, Jiang Yang has seen and heard many cases of death in the car from the police. Most of them are due to the high idle speed of the engine and the insufficient combustion of gasoline, which produces a lot of carbon monoxide. If the doors and windows in the car are closed, it is easy to cause carbon monoxide poisoning. Carbon monoxide is colorless and tasteless, which will be very dangerous.

Zhao Ming did not refute, because Jiang Yang said that the situation is indeed more likely.

However, the suspense did not remain for long, and the forensic department also completed the preliminary test.

Li can came over with a document, "Han team, has completed the preliminary autopsy, the victim's way of death is really very special."

Han Bin asked, "how did he die?"

"He inhaled a lot of nicotine, causing vasoconstriction, spasm, myocardial infarction and sudden death."

Zhao Ming surprised way, "my day, he is really smoked to death?"

Jiang Yang also surprised way, "by, smoking can really kill people, I have to quit in the future."

Li can said, "his situation is different from that of ordinary smokers. He inhaled a lot of nicotine in a short time. I found 19 cigarette butts in his mouth. According to my estimation, he may even eat some cigarette butts into his stomach. He smoked at least dozens of cigarettes in a short time. Quantitative change caused qualitative change, which led to his death."

"Mother of, this murderer is also too ruthless, incredibly use the cigarette to smoke to death, make me have the heart obstacle."

Zhao Ming took out a box of huazi from his pocket. "Brother bin, I don't think I will smoke any more recently. Please keep this box of cigarettes."

Han Bin some can't laugh or cry, "you talk much, listen to forensic Li well."

Li can continued, "there is a pattern similar to Z on the victim's neck. The wound is smooth and not deep. It should be scratched with sharp tools. Although there is some blood left in the wound, it doesn't scratch the artery. It's just skin injury.

In addition, I also found binding marks on the dead. The victim should have been bound before he died. The time of death was between 9:00 and 12:00 last night. "

With that, Li can handed the document to Han Bin, "there are still some information about the victim on it. You can have a look at it."

Han Bin swept one eye, above is some autopsy data.

The victim, Zhang Haonan

height, 181cm

time of death, December 26, between 9 pm and 12 pm.

Place of death, Rongyuan community, underground garage

way of death

After reading, Han Bin had a general understanding in his heart.

After the on-site investigation, Han Bin returned to the Municipal Bureau, and Zhang Haonan's car was also brought back.

Han Bin held a temporary case analysis meeting.

The meeting was attended by the second squadron of the municipal Criminal Investigation Brigade and the Criminal Investigation Brigade of Xinhua branch.

Han Bin sits on the main seat of the conference table, Liao Pingsi and Wang Xiao sit at the bottom of him, and the other members line up in turn.

Han Bin glanced at everyone and said in a loud voice, "we all know the situation of the on-site investigation. We can all say what we think about this case and the progress of the investigation.Liao said, "team Han, I visited some onlookers and found no witnesses to the case. But I know something about Zhang Haonan.

According to one of the residents, the car belonged to Zhang Haonan, but the parking space didn't belong to Zhang Haonan. Zhang Haonan often occupied other people's parking space. Once his parking space was occupied. What's more, Zhang Haonan didn't leave his mobile phone number. He didn't squat in Zhang Haonan until the next morning. The other side didn't think much of it and didn't feel guilty about it.

Another resident said that Zhang Haonan often takes a woman home with her. The woman is wearing a mask and can't see what she looks like, but she has a good figure and fashionable clothes. It looks like a relationship between two people. "

Han Bin asked, "is Zhang Haonan the owner of this community?"

"Yes."

"Are there any immediate family members connected?"

Liao Pingsi shook his head. "Not yet. I'll try to get in touch with my family as soon as possible. For the time being, that's all

Han Bin asked, "what other people have clues?"

Wang Xiao cleared his throat. "I took people to collect the monitoring of the community. The elevator and garage entrance and exit of the community are monitored. According to the monitoring, the suspect got out of the garage at 9:05 last night, which is basically consistent with the forensic judgment of the time of death.

More surveillance video, there is no time to view

Zhao Ming said curiously, "it's so late. It's time for most people to go home to sleep. What's he doing in the garage? Happened to meet the killer again? It can't be accidental. Can it be that the murderer asked him to the underground garage and made an acquaintance commit the crime? "

Liao Pingsi continued, "I also think it was an acquaintance who committed the crime. First of all, the murderer had a certain understanding of the victim. He knew that the deceased and Lin Hongguang had a conflict in the elevator because of smoking. Another, the relationship between them is likely to be different if they can make an appointment to the garage in the evening.

I suggest we check the way the victim communicates. Maybe we'll find out about the killer. "
