A street in the downtown area was completely cordoned off by the police because of a murder in a commissary.

The warm April sun was very comfortable on my body, but when I saw the scene of the murder, this comfortable feeling disappeared in an instant.

Lao Lu stood at the scene of the murder with a frown, and said to me in a low voice: "Ouyang, how much resentment do you think the murderer has with the deceased to be so cruel to her?" ”

I really can't explain Lao Lu's problem, because when human beings are cruel and ferocious, the kind of behavior that exterminates humanity is completely beyond any species on the earth. Hatred, psychopaths, and so on can all contribute to this kind of brutal killing.

Without further ado, I said to Lao Lu: "I'll go investigate the crime scene." ”

Lao Lu looked at me and nodded thoughtfully.

When you walk into the commissary, you can smell a disgusting smell of blood. The area of the commissary is not large, only about ten square meters, although there is no deceased in sight, but on the ground, there is a large reddish-brown bloodstain. Due to the heavy bleeding of the deceased, the blood had not completely dried up when I arrived at the scene.

Based on such a large amount of bleeding, I judged that the deceased must have been caused by the severance of arterial blood vessels. I suspect that the deceased must have had a punctured artery in the neck or femoral artery in the thigh.

In addition to the large pool of blood on the ground, there was a long trail of blood, which led all the way to the back room of the commissary.

But when I saw the deceased, I realized that the trail of blood on the ground was not left by dragging the corpse, but by the deceased crawling.

Seeing this, I frowned, and the pain and fear of this young woman's survival came to my mind.

She crawled to the back room with all her might, just to pick up the landline in the back room and call for help. But her bloodied right hand was hanging on the landline, and she didn't pick up the microphone. Apparently, the deceased was exhausted when he climbed to the landline phone and eventually died next to the phone due to his injuries and excessive blood loss.

The deceased was a woman of about 25 years old, who was wearing a white cardigan on her upper body, but the cardigan had long been stained brown with blood.

She was wearing a pair of light blue jeans, which were also covered in blood because of crawling.

A pair of white sneakers were also stained with blood.

I conducted a preliminary examination of the body and found that the deceased had a total of seven stab wounds on his body, including one stab wound to his right arm, four stab wounds to his abdomen, and two stab wounds to his left leg and thigh.

Based on the pallor of the body, I could determine that the deceased had died of blood loss. The cause of her massive blood loss was the severing of the femoral artery in her thigh. This is because if the femoral artery is damaged, 40% of the body's blood volume will be lost within five minutes.

Based on the temperature of the corpse and the presence of the corpse spots, I concluded that the time of death of the deceased was 3 hours ago. It was about two o'clock in the afternoon, so the time of death of the deceased was about 11 o'clock in the morning.

This made me wonder very much, because this commissary is located in the downtown area, what kind of person would choose to kill the dead in such a place and at such a time? What was his motive for committing the crime? I couldn't figure it out.

That's all there is to the results of a preliminary autopsy. I examined the crime scene again, hoping to find clues left by the murderer at the crime scene.

The first thing I did was to check the back room where the body was. It is smaller than the outhouse, about 8 square meters, and has a bed and a bedside table with a landline phone on it. The body was lying next to the bed and the bedside table.

Apart from these two pieces of furniture, there are no other furnishings. The rest were some groceries piled up in the back room, which apparently was the commissary's warehouse.

No evidence of the murderer was found in the back room, because the deceased climbed into the back room by himself before he died, so it can be seen that the murderer did not enter the back room.

When I got to the outhouse, I first looked at the vicinity of the blood stains on the ground. On the white tiled floor, you can faintly see a large number of footprints. But these footprints overlap with each other, and from what I have seen, there are more than 50 different footprints. So which one is the murderer's footprint? That's hard to determine.

In the outhouse, though, I found something extremely unusual. That is, on the shelf, there is a silver fruit knife with blood on the blade.

I looked at the fruit knife and said to Lao Lu: "Strange, is this knife a murder weapon?" ”

Lao Lu looked at me and said, "I also doubted, but how could the murder weapon be placed in this place?" ”

I looked at the knife, I frowned and said, "The blade of the knife has only one side, and the width of the blade matches the wound of the deceased, I can be sure that this is the murder weapon, at least the same knife as the murder weapon." As for why the murder weapon was placed in this position. I have a suspicion that it may have been the murderer who left the murder weapon here because of his high level of nervousness after stabbing the deceased, leaving his hands on the shelf to do other things. ”

Lao Lu nodded in agreement.

I examined the knife carefully. This is a pure steel fruit knife, and the blade and handle are integrated.

And on the hilt, I found a faint fingerprint. I suspect that the fingerprints were left by the murderer.

After that, I asked the investigating detective to keep the knife and asked for fingerprints to be taken as soon as possible and compared in the fingerprint database.

That's pretty much the case. After that, I walked out of the store and observed the situation around the store. Of course, the main thing I observe is the monitoring around the commissary.

The commissary itself is not equipped with monitoring equipment, but because it is located in the downtown area, there is a lot of monitoring around the commissary.

I made a preliminary observation and found that there was a surveillance probe in the Internet café opposite, and a bank not far from the commissary. There are also monitoring probes set up by the traffic department on the road. Of course, I won't list the number of surveillances in the surrounding shops and street intersections.

I didn't have much effort to extract these surveillance videos, because Lao Lu had already sent someone to extract these video materials.

In the office of the criminal investigation team, I was looking at the autopsy report. The autopsy report clearly stated that the cause of death of the deceased was that she died due to excessive blood loss, and although she was stabbed in the abdomen, none of them were fatal injuries. And the autopsy proved that the fruit knife found at the scene was the murder weapon.

The deceased's name is Wu Jiaxue, female, 26 years old this year, single and unmarried, and a native of Wanzhou. After graduating from high school, he ran the store with his mother.,Kind people.,Never got into a fight with people.。

In order to solve the case as soon as possible, Lao Lu divided the investigation team into two groups. One group is an investigation into the network of the deceased, while the other is a video analysis team. Of course, the investigation of the interpersonal relationship of the deceased will be handed over to the criminal police comrades, and I am more willing to look for clues in the video. This is already an effective method of solving cases in modern investigation.
