This is a murder case, and we found four bodies on the first floor, so the remaining three must be on the second floor.

Li Meng and I glanced at each other and immediately walked towards the second floor.

On the first floor there are three bedrooms in total and a bathroom, each room is brightly lit.

Pools of blood had formed in the hallway, and blood was flowing from the first and second bedrooms.

Gently pushing open the door to the first bedroom, an even stronger smell of blood came.

The sight was shocking, and our hearts were beating when we saw it.

There was blood stains everywhere in the room, not on the walls, on the floor, on the windows, and even on the ceiling.

It was a bedroom, and by the door was a double bed, and on the bed lay a man, blood staining the sheets.

The deceased, a woman who appeared to be an elderly man, was lying on her back on the bed with her calves hanging from the edge of the bed, and it appears that she was sitting on the edge of the bed at the time of the attack.

Under the bedroom window, a little girl was lying.

The little girl, who looked to be two or three years old, curled up on the ground, covered in blood, had stopped breathing.

"Don't even let the children go......"

Li Meng was deeply stimulated by the sight in front of her, and she almost squeezed this sentence out of her teeth.

I was also shocked by what I saw, and hurriedly settled down and walked towards the second bedroom next door.

This bedroom has an open door, still a double bed, and the room is furnished in the same way as the first bedroom.

The difference is that there is a computer desk in this bedroom.

And in front of the computer desk, there was a person lying on his stomach.

The blood stains in this bedroom were not very scattered, and they were all concentrated near the computer desk.

The deceased was a male, teenager, who looked to be in his teens, and had his throat slit.

He wears headphones on his head, one hand on the keyboard, and the other holds the mouse.

Due to the splash of blood, the computer crashes due to entering the blood water, and the computer screen is pitch black.

However, it is not difficult to know from the scene in the house that the teenager was sitting in front of the computer playing a game when he was killed.

With headphones on, he didn't know anything about what was coming, even if the killer had already walked behind him.

So far, we have found a total of four bodies on the first floor and three bodies on the second floor.

This single-surname family, a total of seven people, was not spared, and all of them were killed.

This is a tragic case that occurred on the 30th day of the Chinese New Year's Eve and on the eve of Chinese New Year's Eve.

"How?"

Li Meng and I had just walked down the stairs when Officer Wang, the captain of the criminal police team, who was leading the technical team to investigate the scene on the first floor, hurriedly asked me.

I looked at him and shook my head helplessly.

Officer Wang took a deep breath, clasped his hands on his waist, and didn't know what to say for a while.

"I'm sorry, I'm late."

Just then, a woman's voice came from the door.

We all cast our eyes on her, it was Zeng Lan from the forensic department.

She was standing in the doorway panting with a forensic field investigation toolbox in her hand. It seems that she has just received the task and hurried over.

Looking at her appearance, I inexplicably felt a feeling of pity in my heart.

We are all ordinary people, and we all have families, and we should have sat with our families at this time, but with an order, we had to drop everything and rush to the scene of the crime.

Because that's what we eat, and that's our duty.

Ren Qiushi was doing an on-site autopsy for the male deceased at the door, he turned his head to look at Zeng Lan, and said coldly: "Why are you still stunned, hurry up and work." ”

"Yes!"

Zeng Lan hurriedly stepped forward with the forensic scene investigation toolbox, she had just taken a few steps, Ren Qiushi suddenly made a stop gesture to her, and then said slowly: "Come over again after panting." ”

Zeng Lan was stunned and stayed in place.

Immediately after, she took a few big breaths and walked quickly to Ren Qiushi's side.

It can be seen that she came in a very hurry and was also very tired. And she deliberately restrained her breathing and carried out the autopsy.

This case of destroying the door is, to a certain extent, a serious case, especially when it occurs today in the thirtieth year of the Chinese New Year's Eve, and the social impact is extremely bad.

The cases of the serious crime team are all assigned by the Provincial Public Security Department and ordered by Shen Ruoshan, the leader of the serious crime team. But this case was extraordinary, and I informed the other members of the Serious Crime Unit about the case.

Although the case is not under the jurisdiction of the Serious Crime Unit, I believe that my colleagues in the Serious Crime Unit must be on their way to the case.

According to the introduction of the neighbors of this single-surname family, there are seven people in this family, namely the single-surnamed male owner and the female owner surnamed Liao, and their two children, the eldest son and the younger girl. In addition, there are also the parents of the single male host, and the mother of the female owner surnamed Liao.

Therefore, it is not difficult to judge from the gender and age that the male deceased at the door of the first floor is the single male owner of the family.

He collapsed in a prone position in a pool of blood, with a large pool of blood beneath him, and the blood had a tendency to clot.

The approximate clotting time of blood is about 5 to 6 minutes, and the clotting time of blood at room temperature of 25 degrees Celsius outside the body is normally 2 seconds to 5 seconds, and the lower the temperature, the faster the clotting time. In general, the blood will clot within 5 to 6 minutes, and by 24 hours, the clot will completely shrink and the serum will be excreted. The color of the blood clot will also change from dark red to reddish brown and then brown over time.

Of course, at the scene of a homicide, it is also necessary to analyze the scene, just as a drop of water dries up very quickly, but a basin of water takes a long time.

A large pool of blood had formed at the scene, and blood was flowing from the wound of the deceased, so it took longer for the blood to coagulate.

However, as long as the autopsy is performed, the time of death can be definitively determined.

After the technical team investigated the scene of the deceased's crime, forensic doctors Ren Qiushi and Zeng Lan moved the body to the asana of facing up.

The deceased had a hideous face and seemed to have suffered great pain during his lifetime.

His clothes were stained red with blood, and his clothes were damaged in many places.

"There was a wound on the left front chest of the deceased, and the wound was narrow and long, which was a stab wound from a dagger." Ren Qiushi said slowly.

Then he added: "This is the only wound on the body of the deceased, a fatal wound and an absolutely fatal wound." ”

Zeng Lan carefully observed the wound of the deceased, a blunt angle was flat, and there was a slight tear on one side of the obtuse angle.

"It's a single-edged dagger." Zeng Lan said slowly.

"There were no signs of a fight at the scene, and the deceased's hands were covered with flour, which shows that the murderer acted very quickly, and the deceased was not aware of it at all, nor did he have any defense." Ren Qiushi froze and said in a deep voice.

"Acquaintances commit crimes."
