Rongyuan Community.

Han Bin returned to the second basement floor again, and in order to avoid obstructing the on-site investigation, the onlookers had already dispersed.

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

"What did you find?"

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

This is a Great Wall SUV with a relatively wide body and plenty of room for crime. No signs of moving bodies were found, and there were strangulation marks of ropes around the seats, but no ropes were found inside the car.

At the same time, 46 cigarette butts were found in the car, and many traces of burning by cigarette butts were also found.

In addition, the situation in the car is more complicated, in order to better preserve the crime scene, we are going to bring the car back to the city bureau for further investigation and testing. ”

Han Bin asked, "Did you find anything in the dash cam?"

"The dashcam's memory card was removed. The deceased's mobile phone was not found, but the driving license and driving book were there, and it was confirmed that it was the deceased's vehicle. These are the cases that have been discovered so far. ”

Han Bin nodded, "Brother Ma, it's hard work." ”

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

"Good. ”

Zhao Ming was surprised, "Tut, in such a large space as a car, 46 cigarette butts were found, the victim would not have been smoked to death." ”

Jiang Yang shook his head, "You're quite good at thinking, I haven't heard of anyone who will be smoked to death." ”

Zhao Ming said, "There were no fatal wounds found on his body, so how did he die?"

"In 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 been a police officer for many years, and has seen and heard many cases of death in the car, most of which are due to the high idle speed of the engine, and the insufficient combustion of gasoline produces a large amount of carbon monoxide.

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

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

Li Can walked over with a document, "Team Han, the preliminary autopsy has been completed, and the way this victim died is really special." ”

Han Bin asked, "How did he die?"

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

Zhao Ming was surprised, "My day, he was really smoked to death?"

Jiang Yang was also surprised, "Damn, smoking can really kill people, I have to quit in the future." ”

Li Can said, "His situation is different from 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 estimates, he may even have 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 with cigarettes, which made me feel hindered. ”

Zhao Ming took out a box of Huazi from his pocket, "Brother Bin, it is estimated that I won't smoke for a while now, you can keep this box of cigarettes for smoking." ”

Han Bin couldn't laugh or cry a little, "As long as you talk a lot, listen to Forensic Doctor Li carefully." ”

Li Can continued, "The victim's neck has a pattern similar to Z, the wound is smooth and not deep, it should be scratched with a sharp weapon, although the wound left some blood, it did not scratch the artery, it was only a skin trauma.

In addition, I also found strangulation marks on the deceased's body, the victim must have been bound before his death, and the time of death was between 9 and 12 o'clock last night. ”

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

Han Bin glanced at it, and it was all some autopsy data.

The victim, Zhang Haonan

Height, 181cm

Time of death, between 9 and 12 p.m. on December 26.

Place of death, Rongyuan Community, underground garage

How to die......

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

After the on-site investigation, Han Bin led people back to the city bureau, and Zhang Haonan's car was also brought back.

Han Bin convened an ad hoc case analysis meeting.

Participating 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 the bottom of him, 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. What thoughts are on this case and the progress of the investigation, everyone can say.

Liao Pingsi said, "Team Han, I interviewed some onlookers, but I did not find any eyewitnesses to the case. However, I learned some 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 parking space was occupied, and what was even more infuriating was that Zhang Haonan did not leave a mobile phone number, until the next morning he squatted to Zhang Haonan, the other party still looked unimpressed, and did not have the slightest guilt about occupying the parking space.

Another resident said that Zhang Haonan often takes a woman home, the woman is wearing a mask, and she can't see what she looks like, but she has a good figure and is very fashionable. ”

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

"Yes. ”

"Has his immediate family been contacted?"

Liao Pingsi shook his head, "Not yet." I will find a way to contact the family to identify the body as soon as possible. That's all there is to it for the time being. ”

Han Bin asked, "What other clues do the others have?"

Wang Xiao cleared his throat, "I took someone to collect the surveillance of the community, the elevator and the entrance and exit of the garage in this community are monitored, according to the surveillance, the suspect got out of the garage at 9:5 last night, which is basically consistent with the time of death judged by the forensic doctor."

More surveillance videos, for the time being, have not had time to view. ”

Zhao Ming said curiously, "It's so late, it's time for most people to go home and sleep, what is he doing in the garage? and he happened to meet the murderer? It can't be an accident after all." Could it be that the murderer invited him to the underground garage and an acquaintance committed the crime. ”

Liao Pingsi continued, "I also think that it was an acquaintance who committed the crime, first of all, the murderer had a certain understanding of the victim, and he knew that the deceased and Lin Hongguang had a conflict in the elevator because of smoking. Another one, can make an appointment with the deceased to the garage at night, and the relationship between the two is likely to be unusual.

I suggest checking the deceased's means of communication, and you may find clues about the murderer. ”
