Detective from the future

Chapter 916 Cause of Death
Rongyuan District.

Han Bin returned to the second basement floor again. In order to avoid hindering the on-site investigation, the surrounding residents had been dispersed.

The people from the technical department had finished surveying the site and were packing up the toolbox. Ma Xiwen walked over after seeing Han Bin, "Team Han, the site has been preliminarily surveyed."

"What did you find?"

Ma Xiwen replied, "The surroundings of the car are very clean, nothing suspicious was found, the ground is all concrete, and there are no obvious traces, the crime scene should be inside the car.

This is a Great Wall SUV with a relatively large body and enough space for crimes.There were no traces of moving bodies, and there were rope marks around the seats, but no ropes were found in the car.

At the same time, 46 cigarette butts of Yunyan were found in the car, and many traces of being burned by the cigarette butts were also found. Blood stains and fingerprints were found at the scene, and they 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 plan to take the car back to the city bureau for further investigation and testing. "

Han Bin asked, "Did the driving recorder find anything?"

Ma Xiwen said, "The memory card of the driving recorder was taken away. The deceased's mobile phone was not found, but the driving license and driver's book are there, so it can be confirmed that it is the deceased's vehicle. These things have been discovered so far."

Han Bin nodded, "Brother Ma, you have worked hard."

"It should be, we will close the team first, and I will notify you when there are further identification results."

"it is good."

Zhao Ming was amazed, "Tsk tsk, 46 cigarette butts were found in such a large space in the car. The victim must have been smoked to death."

Jiang Yang shook his head, "You're pretty good at thinking, I haven't heard of anyone being smoked to death."

Zhao Mingdao, "No fatal wound was found on his body, so how did he die?"

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

Jiang Yang has seen and heard many cases of death in cars over the years in the police force. Most of them are caused by high engine idling speed and insufficient combustion of gasoline to produce a large amount of carbon monoxide. If the doors and windows in the car are closed, it will easily cause death. Carbon monoxide poisoning, carbon monoxide is colorless and odorless, this situation can be very dangerous.

Zhao Ming didn't refute it either, because what Jiang Yang said was indeed more likely.

However, this suspense did not last long, and the forensic doctor also completed a preliminary test.

Li Can came over with a document, "Captain Han, the preliminary autopsy has been completed, the way the victim died is quite special."

Han Bin asked, "How did he die?"

"He inhaled a large amount of nicotine, which caused vasoconstriction and spasm, causing myocardial infarction and sudden death."

Zhao Ming asked in surprise, "My god, did he really die from the smoke?"

Jiang Yang also said in surprise, "Damn it, 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 large amount of nicotine in a short period of time. I found 19 cigarette butts from his mouth. According to my estimation, he may have even eaten some cigarette butts into his stomach. , he smoked at least dozens of cigarettes in a short period of time, and the quantitative change caused the qualitative change, which led to his death."

"Damn, this murderer is too ruthless. He actually smoked people to death, which made me even have a mental block."

Zhao Ming took out a box of Huazi from his pocket, "Brother Bin, I don't think I will smoke in the near future, you should keep this box of cigarettes."

Han Bin didn't know whether to laugh or cry, "As long as you talk a lot, listen carefully to Forensic Li."

Li Can continued, "The victim's neck had a pattern similar to a Z. The wound was smooth and not deep. It should have been scratched with a sharp object. Although the wound left some blood, it did not scratch the artery, it was just a skin trauma.

In addition, I also found strangle marks on the body of the deceased. The victim should have been bound before his death, and the time of death was between nine o'clock and twelve o'clock last night. "

After speaking, Li Can handed the document to Han Bin, "There are some victims' information on it, you can take a look."

Han Bin glanced at it, and there were some autopsy data on it.

Victim, Zhang Haonan

Height, 181cm
The time of death was between 12:26pm and [-]:[-]pm on December [-]th.

The place of death, Rongyuan Community, underground garage
way of dying...

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

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

Han Bin held a temporary case analysis meeting.

Those who participated in the meeting were people from the Second Squadron of the Municipal Criminal Investigation Brigade and the Criminal Investigation Brigade of the Xinhua Branch.

Han Bin sat at the head of the conference table, Liao Pingsi and Wang Xiao sat at his lower head, and the other team members lined up in turn.

Han Bin glanced at everyone, and said loudly, "Everyone knows the situation of the on-site investigation. Everyone can talk about their thoughts on this case and the progress of the investigation.

Liao Pingsi said, "Team Han, I visited some onlookers, but I didn't find any witnesses to the case. But I did learn about Zhang Haonan's situation.

According to one of the residents, the car belonged to Zhang Haonan, but the parking space did not belong to Zhang Haonan. This Zhang Haonan often occupied other people's parking spaces. Once his family's parking space was taken, and what was even more annoying was that Zhang Haonan hadn't kept it yet. He didn't squat to Zhang Haonan until the next morning, and the other party still looked indifferent, without the slightest guilt about occupying the parking space.

Another resident said that Zhang Haonan often took a woman home. The woman was wearing a mask and couldn't see what she looked like, but she had a good figure and fashionable clothes. Judging by the behavior of the two, it seemed that they were in a relationship. "

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

"Yes."

"Has anyone in his immediate family been contacted?"

Liao Pingsi shook his head, "Not yet. I will find a way to contact the family members to identify the body as soon as possible. That's all for now."

Han Bin asked, "Any other clues?"

Wang Xiao cleared his throat, "I took people to collect the surveillance of the community. The elevators and garage entrances and exits in this community are all monitored. According to the surveillance, the suspect got off the garage at [-]:[-] last night, and the forensic doctor judged his death. The timing basically coincided.

For more surveillance videos, I haven't had time to view them yet. "

Zhao Ming asked curiously, "It's so late, most people should go home to sleep, what is he doing in the garage? And he happened to meet the murderer? After all, it couldn't be a coincidence. Could it be that the murderer invited him to the underground garage, an acquaintance crime."

Liao Pingsi went on to say, "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. Second, he was able to invite the deceased to the garage at night. The relationship between the two is likely to be unusual.

I suggest checking the communication method of the deceased, maybe you will find clues about the murderer. "
