These days, there are no cases, and I can leave work on time.

Han Bin had dinner with his parents, put on headphones, listened to novels, and walked around the community.

The greening of the Huayuan community is good, and Han Bin enjoys this comfortable walk.

When I was tired of walking, I sat in a chair, listened to a novel, and occasionally smirked, attracting the curious eyes of others.

Not far away, three people walked in, and a man in the middle was very familiar, and Han Bin fixed his eyes and saw that it was his colleague Li Hui.

The two people next to him, the man was wearing a white shirt and trousers, and the woman was wearing a professional skirt with a badge on her chest, and she looked like people from an intermediary company.

Han Bin got up and said, "Yo, isn't this Officer Li?

"It's been a long time, why is Officer Han here?" Li Hui showed an exaggerated expression.

Han Bin lowered his head and glanced at his watch: "It's been quite a long time, it's been almost two hours." ”

The intermediary salesman next to him was a little crying and laughing.

"Binzi, why are you in this community?" Li Hui said.

"That's where I live. Han Bin said.

"Damn, isn't that supposed to be your neighbor in the future?" Li Hui said in surprise.

"You want to buy a house here?" Han Bin said.

"Just kidding, the housing prices are so high, how can I afford them. Li Hui shook his head: "I'm going to rent a single room." ”

"The environment of this community is okay, I will accompany you around. Han Bin said.

Han Bin's family lives in Building No. 6, and the house Li Hui looks at is in Building No. 9, and the room number is 801, which is similar to the house type of Han Bin's house, with three bedrooms, two living rooms, and two bathrooms.

After entering the door, the female saleswoman of the intermediary introduced that there are two houses for rent, one is the master bedroom with bathroom, and the other is the south-facing side bedroom, Han Bin just glanced at it, and he was not interested in looking at it, it was the same as their house.

"How much is the rent for these two houses?" asked Li Hui.

"Seven hundred for the master bedroom and five hundred for the second bedroom. The saleswoman said.

"Can it still be cheap?" Li Hui said.

"That's already the lowest price. The saleswoman said.

Li Hui looked in the room and said, "Is there another room where people live?"

"Stayed, it's a female tenant. The saleswoman said.

"Well, I probably understand the situation, think about it again. Li Hui said.

After going downstairs, the salesmen of the two intermediary companies left, and Han Bin and Li Hui stayed to chat.

"Binzi, do you think it's expensive?" Li Hui said.

"It's okay. ”

"Then which room do you think I should rent?" Li Hui said.

"Which room do you prefer?"

"Of course it's the master bedroom, but it's more expensive. Li Hui said.

"Then rent the master bedroom, it is also convenient to have a bathroom, and it is more private. Han Bin said.

Li Hui nodded.

"It's good to rent this, live close to have a care. Han Bin said.

"I can also go to your house to eat. Li Hui said with a smile.

......

Han Bin's house doesn't fire every day, and sometimes in the morning, he will go to the bureau's canteen to eat.

A xiaolongbao, a tea egg, and a carton of milk, the criminal police can't say who will go out on a mission, don't eat more, and can't bear it.

After Han Bin finished eating, he went to the office and saw that Li Hui, Tian Li, and Zhao Ming had already arrived.

After saying hello, Han Bin was ready to make a cup of tea.

Zeng Ping walked in quickly and slapped his face: "Papapa......"

"Pack up and get out of the scene. ”

"Team Zeng, what's the case?" asked Han Bin.

"Homicide. ”

Since it was a homicide, it was definitely not a trivial matter, so everyone packed up and immediately got in the car and rushed to the scene.

He was accompanied by a technical team.

"Team Zeng, why didn't the people from the forensic department come?" Tian Li said.

"Forensic Doctor Chen went to the provincial hall to study, and there was also a murder case on the side of the first team, and Forensic Doctor Wu has not returned from the scene yet, and he will go there later. Zeng Ping said.

"Team Zeng, what's the specific situation?" Han Bin said.

"The informant's name is Li Yu, a high-speed toll collector, who worked the night shift last night, and when he returned home in the morning, he saw her husband Xing Jianbin hanged. Zeng Ping said.

"Did he kill or kill himself?"

"I don't know. Zeng Ping said.

Hanging is an unnatural death, and it is necessary to report to the police, and the criminal case can only be dealt with after the police investigation excludes the criminal case.

......

The crime scene was in the suburbs, in an urban village.

The police at the police station have already set up a cordon, and there are many onlookers around, pointing at a small three-story building.

Han Bin got out of the car, looked around, and found no camera.

Entering the gate, there is a small courtyard inside, and in the middle of the courtyard is a small three-story building, which is beautifully built.

Han Bin put on shoe covers and gloves, and when he entered the hall on the first floor, he saw a rope tied to the electric fan, and a short man with short hair was hanging from it.

On the sofa next to her, there was a woman in her thirties, with her head bowed, hiding her face and sobbing.

"Team Zeng, can you put the body down, let's take pictures and collect evidence. Lu Wendao.

Team Zeng nodded: "Put it down, try not to destroy the corpse." ”

Zhao Ming was a bold man, and volunteered to work with Lu Wen to put the body down and lay it flat on the ground.

Zeng Ping squatted aside, observing the corpse, and only when it was judged whether it was suicide or homicide, the criminal investigation team could carry out the next step of investigation.

If it's suicide, then take it and leave.

If it's him, follow the lead.

Han Bin did the same, squatting aside to observe, and then boldly touched the corpse with his fingers.

"I think the time of death of the deceased should be more than nine hours. Han Bin said.

"How do you know?" asked Li Hui.

"People usually start to stiffen within half an hour to two hours after death, and after 9-12 hours, the whole body stiffens. Han Bin said.

These case-solving knowledge points were all exchanged by Han Bin from the criminal investigation knowledge base with merit points, as if engraved in his mind, and they were easy to use.

"Then did he commit suicide or did he kill him?" Tian Li said.

Han Bin looked at the scar on his neck carefully, and said, "He killed." ”

"How do you know?"

"There are two main points, the first point is the strangulation marks, the strangulation marks of the hanging are about 45 degrees inclined upwards, and the strangulation marks are usually backwards. Han Bin said.

Everyone nodded, they could all understand this.

"What about the second point?" Tian Li said.

"The cause of death by hanging is not what we usually think of as suffocation, although the airway is indeed blocked during the hanging process, which will make the victim feel "out of breath", but in fact, the real cause of death of hanging suicide is the obstruction of blood vessels in the neck, so that the brain cannot obtain oxygen and blood supply from the lungs, resulting in cerebral ischemia. Han Bin said.

"What's the difference between this strangulation?" Li Hui said.

"The blood vessels of the hanged are blocked, and the head cannot get enough blood, so the face of the person who hangs himself usually turns pale. ”

Han Bin pointed to the deceased's face over and over again, and said, "For those who are strangled to death, there will be a lot of bruises on the victim's face and neck, and it will be dark red. ”

"Really!" Zhao Ming said.

"Good analysis. A man's voice rang out.

Everyone turned their heads to look and found Zheng Kaixuan standing aside, watching with interest.
