Detective from the future

Chapter 20 New Cases

There have been no cases in the past few days, and the second group 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.

When he was tired from walking, he sat in a chair and listened to novels, occasionally giggling, attracting curious eyes from others.

Three people walked by not far away, and the man in the middle was very familiar. Han Bin looked closely, and 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 stood up: "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 neighborhood?"

"I live in my house."

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

"Are you going to buy a house here?"

"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's house lives in Building No. 801, and the house Li Hui is looking at is in Building No. [-]. The room number is [-], 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 them. There are two houses for rent, one is the master bedroom with bathroom, and the other is the side bedroom facing south. The house and the house are the same.

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

"The master bedroom has a bathroom of 1200, and the south-facing side bedroom is 1000." The saleswoman said.

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

"Mr. Li, this is already the lowest price."

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

"I live, it's a female tenant." The female salesman pointed to the direction of the second bedroom.

"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 was a little undecided.

"Okay."

"Then which room do you think is better to rent?" Li Hui touched his chin.

"Which room do you like?"

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

"Then rent the master bedroom. It is convenient and more private to have a bathroom."

Li Hui nodded, feeling a little pain in the flesh again, but it was 1200.

"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 of the branch to eat.

A roujiamo, a xiaolongbao, a box of milk, the criminal police can't tell when the task will be released, and I can't bear it if I don't eat much.

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; there was also a murder case in the first team. Forensic doctor Wu appeared on the scene and has not returned. He will pass later."

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

"The informant, Li Yu, was 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."

"Kill him? Or commit suicide?"

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

Hanging is an abnormal death and needs to be reported 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 camera.

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

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

On the sofa next to her, sat a woman in her 30s, sobbing with her head lowered and her face covered.

Lu Wen looked up: "Team Zeng, can we put the body down? We need to take pictures and collect evidence."

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

Zhao Ming was daring, he volunteered to put the corpse down with Lu Wen, and laid the corpse flat on the ground.

Zeng Ping squatted aside to observe 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 and squatted aside to observe, then boldly touched the corpse with his fingers.

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

"How do you know?" Li Hui leaned over.

"A person usually begins to be rigid within half an hour to two hours after death, and the whole body becomes rigid after 9-12 hours."

These case-solving knowledge points were 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 observed the scar on his neck: "Kill him."

"How did 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, while the stranglehold of homicide is usually backwards." Han Bin explained.

Everyone nodded, and they all understood this.

"What about the second point?"

"The cause of death by hanging is not asphyxiation as we usually think of it, although the airway is indeed blocked during the hanging process, making the victim feel 'out of breath'; 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 to death?" Li Hui still didn't understand.

"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 at the face of the deceased again and again: "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 that Zheng Kaixuan was watching with interest.
