Twenty New Cases

These few days, there are no cases, so I can get off work on time.

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

The greening of Huayuan Community is well done, and Han Bin enjoys this comfortable walk.

Tired of walking, sitting in a chair, listening to a novel, occasionally giggling, attracting curious eyes from others.

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

The two people next to them, the man was wearing a white shirt and trousers, and the woman was wearing a professional dress with a work badge on his chest, which looked like people from an agency.

Han Bin got up and said, "Yo, isn't this Officer Li? Why did you come here?"

"Long time no see, why is Officer Han here?" Li Hui showed an exaggerated expression.

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

The intermediary salesman next to him was dumbfounded.

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

"I live in my house." Han Bin said.

"Damn, wouldn't that mean that I want to be your neighbor in the future?" Li Hui said in surprise.

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

"Just kidding, the price is so high, how can I afford it." Li Hui shook his head: "I'm going to rent a single room."

"The environment in this community is okay, I'll accompany you around." Han Bin said.

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

After entering the door, the salesperson of the agency introduced that there are two houses for rent, one is the master bedroom with bathroom, and the other is the side bedroom facing south. Their houses are the same.

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

"The master bedroom is seven hundred, and the second bedroom is five hundred." The female salesman said.

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

"This is already the lowest price." The saleswoman said.

Li Hui looked around the room and said, "Is there another room to live in?"

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

"Well, I understand the situation, and 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.

"Okay."

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

"Which room do you like?"

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

"Let's rent the master bedroom. It's convenient to have a bathroom, and it's more private." Han Bin said.

Li Hui nodded.

"It's fine to rent here, if you live close by, there will be someone to take care of." Han Bin said.

"I can still go to your house for a meal." Li Hui smiled.

...

Han Bin's house didn't open fire every day, sometimes in the morning, he would go to the cafeteria in the bureau to eat.

A xiao long bao, a tea egg, a carton of milk, the criminal police can't tell when the task will be released, don't eat more, 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 prepares to make a cup of tea.

Zeng Ping walked in quickly and clapped his hands: "Papapa..."

"Pack up and show up."

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

"Murder."

Since it was a murder case, it was definitely not a trivial matter. Everyone packed up and immediately got in the car and rushed to the scene.

Accompanying the technical team.

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

"Forensic doctor Chen went to the provincial office to study; the first team over there,

There was also a murder case. Forensic Wu appeared on the scene and has not returned. He will pass later. " Zeng Ping said.

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

"The reporter is Li Yu, a high-speed toll collector. He worked the night shift last night. After returning home in the morning, he saw her husband Xing Jianbin hanged." Zeng Ping said.

"Kill him? Or commit suicide?"

"I don't know." Zeng Ping said.

Hanging is an abnormal death, and it is necessary to report to the police.

...

The crime scene was in the suburbs, a village in the city.

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

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

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

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

On the sofa next to her, a woman in her thirties sat with her head lowered and her face sobbing.

"Team Zeng, can we put the body down? Let's take pictures and collect evidence." Lu Wen said.

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

Zhao Ming was daring, and volunteered with Lu Wen to lower the body and lay it flat on the ground.

Zeng Ping squatted aside and observed the corpse. Only after judging whether it was suicide or homicide can the criminal investigation team carry out the next step of investigation.

If it is suicide, then close the team and leave.

If it was homicide, follow up the clues.

Han Bin followed suit, squatted aside to observe, and then boldly touched the corpse with his fingers.

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

"How do you know?" Li Hui asked.

"People usually start to be stiff within half an hour to two hours after death, and the whole body will be stiff after 9-12 hours." 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 handy to use.

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

Han Bin carefully looked at the scar on his neck and said, "Kill him."

"How do you know?"

"There are two main points. The first point is the streak. The stranglehold of the hanging is about a 45-degree angle upwards, and the stranglehold of homicide is usually backwards." Han Bin said.

Everyone nodded, and they all understood this.

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

"The cause of death by hanging is not asphyxiation as we usually think, although the airway is indeed blocked during the hanging process, making the victim feel 'out of breath'; but in fact the real cause of death by hanging is the obstruction of the 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 one strangled?" Li Hui said.

"The hanging blood vessels are blocked and the head can't get enough blood, so people who hang themselves usually turn pale."

While speaking, Han Bin pointed to the face of the deceased and said, "For those who were strangled, the victim's face and neck would be heavily bruised and dark red."

"Really!" Zhao Ming said.

"The analysis is good." A man's voice sounded.

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