As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

Niu Xiaowei gradually regained consciousness. He felt pain all over his body, including in his head and stomach. He felt a little cold and had no strength at all.

He struggled to open his eyes. It was already dawn and he found himself lying on the floor of his home. It was all red, with lots of blood on the floor.

He wanted to scream out in fear, but no sound came out.

He moved and felt a piercing pain in his stomach. He looked down and saw a dagger stuck in his stomach.

An extreme feeling of fear spread throughout his body, and he shouted with all his might, "Dad, Mom!"

But no one paid any attention to him. He looked at the dagger that was still half exposed and wanted to pull it out, but he didn't dare. He stretched out his hand that was stained with blood from somewhere and took out his cell phone.

I pressed those three numbers: 110, "Hey, there's a knife in my stomach, I..."

Niu Xiaowei's voice suddenly stopped and his eyes looked to the other side of the floor.

"Hello, are you still there? Please tell me your address." The operator's anxious voice came from the other end of the phone.

"Murder, murder, my parents are dead, my parents were murdered." Niu Xiaowei shouted excitedly.

On the other side of the floor, there were two bodies lying in a pool of blood. They were the parents who had just quarreled with Niu Xiaowei yesterday afternoon.

"Sir, calm down and tell me the address."

"Room 7, Unit 1, Building 402, Lanyuan District , please save me, and save my parents."

......

Early in the morning, Ye Lin had just arrived at the office and was about to ask Sun Jinghua and others to invite Meng Xianmin back to record his statement when his cell phone rang.

He looked down and saw it was Li Suo.

"Chief Officer Li, do you have any good news so early in the morning?" Having worked on a case together for a day, Ye Lin had become familiar with Chief Officer Li, so he started joking.

A bitter laugh came from the phone: "Good news, more deaths, two dead and one injured, Lanyuan District 2, please bring someone over quickly."

Eh...

Ye Lin couldn't help but curse as he held the beeping phone, what a world.

"Xiao Sun, Sister Shanshan, let's go. There is work to do."

At 6 am on June 16, Ye Lin arrived at the scene.

"Captain Li, what's going on with you? It's happened twice in a row." Ye Lin complained.

Chief Li also had a look of helplessness and bitterness on his face. After two consecutive cases, the police station’s ranking would be lower this year, and it would definitely lose the advanced title.

"No need to talk about it anymore. Let me tell you about the case first."

"The deceased were an elderly couple, both retired, who were stabbed to death. Their son was also stabbed, but luckily he survived and has been sent to the hospital."

"Look, there's blood all over the floor, more than Zhang Liqin's blood." Chief Li pointed inside the room.

Ye Lin leaned over to take a few looks. The floor was covered with blood. Some of it was splattered, and some of it was in pools. Considering the amount of bleeding, it would be hard to survive.

"Two people were killed in the living room, but didn't anyone hear anything from next door?" Ye Lin asked curiously.

"It really happened. There was a young couple upstairs who went to bed late. They heard an argument in the middle of the night and the sound of something falling, but it died down quickly."

"How did the murderer get in? Through the door or the window?" Ye Lin looked around. This was the 4th floor, so there was a certain possibility that he got in through the window.

"We checked and the door lock was not broken. This community is equipped with anti-theft windows, so the window is impossible. Either they have a key, or the door was opened from the inside."

Chief Li gave a brief introduction. Ye Lin's heart sank. He was the one who opened the door again and then was killed. Why are doors so easy to open nowadays?

Ye Lin put on shoe covers and walked in. On-site investigation is a must. No matter how much information you read, it will not be as intuitive as seeing the scene in person.

This is a large two-bedroom apartment, estimated to be 70 square meters, which is quite suitable for two elderly people to live in.

There was blood all over the floor of the living room. Relatively speaking, the place where the old couple was killed was close to the bedroom, and the place where their son was lying was close to the door.

Judging from the shape of the blood on the ground, there are mainly two types: one is the splashing particles turning into blood, and the other is a pool of blood.

The splatter should be formed by the blood spurting out under the action of blood pressure when the knife was stabbed. There was such a thing around the old couple, and then after the two people lay down, they flowed out of their bodies to form a large trace of blood.

Ye Lin spread his legs and stood roughly in the position of the two men. He looked at the blood distribution around him. He should have been stabbed more than once, and the old man was stabbed first, and then his wife came out and was also killed, because his wife was closer to the bedroom.

The blood on the ground had been stepped on in some places, but there was no complete shoe print.

There is a window in the living room with an anti-theft window, so no one can get in.

There is a dining table against the wall, and opposite it is a fish tank with water plants and rockery, but no fish can be seen. Ye Lin guessed that it was for landscape purposes.

There is also an old-fashioned cabinet in the living room, with some ornaments and sundries on it, and there should be some things stored underneath as well.

There are two bedrooms in the house. One belongs to an elderly couple. The things there are quite old and the quilt on the bed is in a mess. It seems that the elderly couple just climbed out of the bed and were killed.

The other room should be their son's room, the adult room, with a computer, stereo and other things, but the quilt is still folded on the bed and no one has slept in it.

Ye Lin couldn't see anything else either, so he would wait until the technical department came to collect traces before deciding.

Ye Lin came out, looked at Li Suo and asked, "You said his son is still alive?"

"Well, the hospital called just now. He was stabbed in the abdomen and the bleeding was heavy. If we had come an hour later, he would have died. He is now past the critical stage, but still very weak."

"Xiao Sun, Qi Shan, you guys stay at the scene and cooperate with the work. Li and I will go to the hospital." Ye Lin wanted to know the situation from the survivors as soon as possible.

"Okay, let's go."

......

Niu Xiaowei is now living in the intensive care unit. He had just undergone surgery and was still plugged into various monitoring devices. His stomach and head were wrapped in large circles of bandages. He looked completely bloodless, and even his lips were white.

Ye Lin studied medicine, and he couldn't help but sigh that this kid was lucky enough not to die.

Seeing the police coming in, Niu Xiaowei moved his body and asked softly: "Comrade police, my parents?"

He didn't dare speak loudly for fear of causing the wound on his stomach.

"Your parents had already been killed. They were too late to save them when we arrived." Li Suo said with a hint of apology.

Niu Xiaowei's expression darkened. He still couldn't accept that both his parents had died just like that.
