Criminal Investigation Notes

The body that had just been fished out of an abandoned oil drum was a young man.

The clothes on the corpse were still wearing, just an ordinary T-shirt and a pair of black trousers. The corpse's shoes were taken off, and one pair of feet was bare.

Su Hui couldn't see the body clearly, so he squinted and put on a mask and leaned over to see.

The flesh on the corpse's face seemed to have been dug from the inside, the eyeballs were sunken, the cheeks were sunken, the skin was a strange burnt yellow, and the soft tissue of the face had become a thin layer, like a layer The human skin was attached to the skull.

After being soaked for a period of time, the corpse became very soft, those joints seemed to slip out of the bone groove, and the flesh and blood had changed its state, like a puddle of soft butter.

The forensic doctor lifted the corner of the clothes, and Su Hui could see that the body was sunken below the sternum, and the front abdominal wall was almost against the spine, like a boat.

In medicine and forensics, this is called a navicular depression.

Under the rib of the corpse, many knife marks can be seen. Those knife marks are densely packed, there may be more than a dozen knives, and there may be more.

Su Hui squatted down and looked at the stab wounds. Many of the stab wounds were very close to each other. One could see the madness and irritability of the murderer.

Lu Junchi raised his head and asked the little forensic doctor, "Can you determine the time of death based on the degree of decay?"

In this chain of multiple-body cases, determining the time of death can help clarify the status of the case.

The little forensic doctor, who was probably an intern, said hesitantly, "The body is soaked in oil, and the usual way of measuring time is useless. Wait for Sister Jing, she should know."

At this moment, Xing Jing walked in from the outside and said, "Is this also done?"

Then she calmly looked at the corpse on the ground, stretched out her rubber-gloved hand and pressed the corpse's skin and abdomen, some gasoline seeped out of those knife edges. It appeared that gasoline had soaked the body from the inside out.

She judged for a while and said, "This one was killed before, and the soaking time was about two months. The other one is fresher, it should be more than a month. Therefore, whether it is from the time of discovery or the time of killing, The one in front of you is the No. 1 male corpse."

The little forensic doctor took a few pictures of the corpse and asked, "The abdomen is very sunken. Is this caused by the wound, or was the murderer dug out the internal organs?"

Xing Jing said: "Not necessarily, the oil will cause the atrophy of the organs, and his lungs may shrink to the size of a palm. The heart will also shrink sharply."

The little forensic doctor suddenly said: "The oil will cause such great damage to the corpse."

Xing Jing snorted: "Oil and water and other liquids have different properties. Oil-immersed corpses are not very common, and they are not written in textbooks. I have only encountered one before after working for so many years. At that time. The deepest memory is the brain tissue. These oils will turn the brain into mud. However, oil immersion is also good for us forensics, that is, the food in the stomach can be well preserved by the oil, even after a long time. It won't be bad either, and it can be used as a forensic reference."

The master and apprentice discussed as if no one else was around, and the Wujian next to him turned pale and nauseated.

Lu Junchi looked at Su Hui's indifferent expression. They had almost seen the scene. Lu Junchi suggested, "Let's go to the other side?"

Su Hui hummed.

The other site is 100 meters away from this one, which is an old farm. As soon as you enter, you can smell the smell of animal feces. There is a larger oil drum, and there are some traces of oil on the ground.

A slightly fat male body was fished out, and half a barrel of oil was put aside. The oil inside was cloudy.

In contrast, this No. 2 corpse is "fuller" than the other, and the wounds are two cuts in the chest.

"What kind of oil is this oil?" Lu Junchi asked. There was some gasoline smell in the air, but not too strong.

Wu Jian said: "It should be a mixture of edible oil and gasoline."

Su Hui looked at the corpse for a while, and suddenly asked the book of objects taken next to him: "What did this corpse look like when it was found?"

The Wujian hurriedly adjusted the photo and showed it to him. It was different from the previous corpse. This corpse was stuffed in an oil barrel. From the surface of the oil barrel, you could see some hairs floating around. You can vaguely see the raised feet.

Zheng Bo squatted aside and asked, "Are we looking for a serial killer targeting adult males in this case?"

Qiao Ze used what he knew and tried to analyze: "Serial killers have certain criteria for choosing victims. Most serial killers target women, a few target children, and some target the elderly. Serial crimes by men are less common, but there are, and many of them hunt men because of their sexual orientation..."

For those murderers, thin victims will satisfy their desire to bully, while strong victims, especially adult men, will bring many variables and dangers to the murder process.

Su Hui coughed a few times, but did not speak.

Lu Junchi looked at the scene and raised his head: "The murder knives in these two cases are similar, the method of storing the corpse is similar, but the person who abandoned the corpse may be different."

Qiao Ze, who was holding the small notebook, was a little stunned. The good student raised his face and asked diligently, "Captain Lu, what is the basis for your judgment?"

At two crime scenes less than 100 meters apart, two male corpses were soaked in oil barrels. big.

"Pay attention to the oil stains on the ground here." Lu Junchi narrowed his long and narrow eyes slightly. He pointed to the messy oil stains on the ground. Some of the oil spots caused by the forensic handling were still wet. oil marks are distinguished.

"Those old oil marks are a relatively uniform circle, not like sporadically splattered when the oil was poured in. Then it is likely to be the oil splattered when the body was put in."

He pointed to the marks on the side of the barrel and continued.

"The oil barrel of the first corpse was clean, with only a few oil spots, but this barrel was messy with a lot of oil stains. I suspect that the first barrel was put into the corpse first, in order to prevent the corpse from rotting and attracting insects. It smelled, so it was filled with gasoline, and this second time, the murderer put more than half of the oil in the barrel first, and then threw the body in."

Zheng Bo was a little puzzled: "Why did you put the oil first and then put the body?"

Lu Junchi said: "We are not at the scene, it is difficult to judge. It may be that the murderer was in a hurry and made a wrong step, or it may be that the oil drum and oil have already been placed here, and the murderer just used it to throw the body."

All signs showed that the second time the body was thrown, it was much more panic than the first time.

Su Hui coughed a few times and gave Lu Junchi a look of approval, then he whispered: "I will add that these two corpses are not low in height. Especially the second corpse, except for the phenomenon caused by oil dissolution and so on. Destruction, the deceased should have been between 150 and 200 jin before his death. Even an adult man would be very difficult to carry such a weight. The height of the oil drum is about 1.3 meters, and the diameter is about that much. , although it looks big, it is still a bit small compared to the corpse, and it is basically impossible for the corpse to be turned inside. The first corpse was placed head down. This placement method is relatively simple and more common sense. The body is placed in a V shape, which is much more difficult."

When a normal corpse is put in, either the head rushes down and curls up, or the feet rush down and curl up, placing it with the buttocks as the bottom, it is very strange.

And this placement is much more difficult than the first placement, there is no reason why the second action is so inexperienced.

Qiao Ze remembered here, raised his head and asked, "Then how did this corpse go in?"

Zheng Bo lowered his head and thought for a while: "Either the princess is holding it, or..."

He was stuck here and couldn't think of any other possibility.

Zheng Bo thought for a moment and turned to Qiao Ze and said, "Just try this and you'll know." He hugged him without waiting for Qiao Ze to react.

Qiao Ze was suddenly picked up, and he was so frightened that he reached out and grabbed Zheng Bo's clothes, for fear of being thrown away.

Zheng Bai smiled wickedly and looked down at him: "What are you afraid of, I'm just making gestures, and I won't really throw you into the oil barrel."

After speaking, he swayed provocatively and walked to a place very close to the oil drum.

Qiao Ze tightened his grip, gritted his teeth and said, "Zheng Bo, if you dare to drop me, then all the records will be yours!"

Having said that, he was quite cooperative, trying to pose as the deceased was in the barrel when he was found, and instructing, "Oh, you're not using your strength, the body isn't sitting, it's a bit like V-shaped!"

Zheng Bai said: "If you move around again, you will really fall."

The more he talked, the more difficult it became to pose. In just a short time, Zheng Bo was sweating profusely.

Zheng Bai was nearly 1.9 meters tall and had muscles all over his body. Qiao Ze was only about 1.7 meters tall and thin. With such a difference in height and weight between the two, it would be difficult to put Qiao Ze into the bucket in that position.

Not to mention that the living can cooperate, but the dead are dead.

When Lu Junchi saw this, he felt that this method would not work: "The second corpse looks like a fat man with a height of nearly 1.8 meters, he must be heavier than Qiao Ze, your attempt like this just shows that the posture of the princess is not feasible. ."

Zheng Bai asked, "Isn't it possible that when the bucket was dumped, people were put in first?"

"There's oil in the bucket!" Qiao Ze pinched him, "Have you forgotten the splash marks on the ground?"

Su Hui looked at their movements but suddenly remembered something, and said, "Unless... two people are carrying it."

In that position, the deceased's hands were hanging down, rather like being held by two people, one with his armpits, the other with his feet, and put them into the bucket.

His words made everyone suddenly enlightened.

Lu Junchi carefully observed the splash marks next to the oil drum, and further concluded: "There are fewer splash marks on the position where I stand and the 180-degree opposite position, and these are exactly the two places where the head and feet of the corpse were originally placed. Orientation. This means that it happened that the bodies of the two people who abandoned the corpse blocked some of the oil spills."

The ground of this farm is full of broken soil. I tried to extract the footprints from the physical evidence just now. After searching for a long time, I couldn't find a complete one, but the oil marks revealed the number and location of the abandoned corpse.

Lu Junchi looked at it and said, "One of the people's feet is a little small...it may be a woman."

The two blanks are obviously slightly different. The area of ​​one is much smaller than the other, and it is located in the direction of the feet.

Qiao Ze asked: "Is it possible that it is a minor?"

Lu Junchi carefully observed the oil stains and said, "The shoes may be pointed, and they look a bit like small high heels, not like minors."

The corpse dumper must have been aware of the murderer's murder, and the number of people involved is increasing...

Only then did Zheng Bai put Qiao Ze down: "Is that a serial killer? But many people are involved in throwing corpses? For example, parents help?"

"There are many other possibilities..." The smell inside was so unpleasant that the smell of gasoline made people's minds not turn their heads. Su Hui coughed repeatedly when he said this.

Several people analyzed the traces at the scene of the corpse throwing, so it sounds like the case is more complicated.

Lu Jun said lately: "We still wait for the results of the physical examination and forensic medicine, compare the disappearance records, and determine the identities of the two victims first."

He looked at the time and said to the two subordinates, "Let's do a search in the neighborhood first."

After leaving the scene of the corpse throwing, Su Hui felt that his breathing was smoother. In addition to collecting physical evidence, the forensic doctor had to take the corpse away for autopsy, and the criminal police also needed to visit the nearby people.

Zheng Bo and Qiao Ze went with a tacit understanding. Lu Junchi also found a police assistant and asked the person who found the body in the first place.

Su Hui watched Wu Jian busy for a while, then sat aside to rest.

There are no villages in front of this place, no shops in the back, and neither has been demolished nor sold. It is sparsely populated and there are not many nearby residents.

After eleven o'clock, the weather warmed up a little, Su Hui was in a daze, and suddenly saw a bottle of mineral water swaying in front of him.

He looked up and saw Lu Junchi looking at him.

Su Hui took it and found that the water was still warm. He was curious, "Where did you buy this? It's still hot."

Lu Junchi sat next to him and said, "I brought it myself. I put two bottles on the back seat when I locked the car, and it was warmed up after a while, just to drink."

Lu Junchi felt that it was inconvenient to hold the thermos cup. They often appeared on the scene, and they always carried a box of mineral water in the car. When the temperature in the car was hot in spring and summer, the temperature in the car could reach 50 degrees. In winter, it was stuffed in the engine compartment for a while. . Food-grade plastic can withstand 70 degrees of temperature and will not be scalded.

He didn't think that being a criminal policeman must mean the wind, the sun and the rain. Lu Junchi was used to taking care of his younger brother since he was a child, and he was used to taking care of his colleagues after work.

In the past, Su Hui always thought that the criminal police was a chore, and being a serious crime team was even more stressful and fast-paced, but Lu Junchi always had the ability to arrange everything in an orderly manner without any chaos. He never let himself feel wronged. Embarrassed, even with someone who can take good care of him and the people around him.

Su Hui drank the water and lowered his head, thinking that Lu Junchi took care of people meticulously, and his care would not cause any burden to people.

It's like after he came here, Su Hui found that the house became clean, neat, warm, organized, and he would make all kinds of tricks for three meals a day.

Sometimes Su Hui frowned, and Lu Junchi knew what he wanted and what he wanted to do.

He would remind him to get up early and remind him to bring an umbrella.

His office is always stocked with all kinds of things, standing medicines, stationery and tools that will be used, neatly lined up like a treasure chest.

Such a friend, or a colleague, it is difficult for you not to have a good impression of him. Even with the two cats at home, they like him very much, and sometimes lie down and show their belly to touch him.

Su Hui had almost no resistance to his gentleness.

When getting along with him, he sometimes forgets that this person is a little younger than him.

It was difficult for him to describe whether Bureau Tan sent him a bodyguard or a nanny.

Not to mention that Lu Junchi is still handsome, reliable, and able to give people a sense of security...

Thinking about it, Su Hui felt a little hot on his face.

He put the water bottle on his cheek, trying to cool down, but remembering that the water was warm, made his cheek even hotter.

At this moment, Qiao Ze and Zheng Bai had already returned, sweating on their heads. Lu Jun threw two bottles of water over, and the two took it. They drank a few mouthfuls before speaking.

Zheng Bai: "We have found the source of the oil drum. There is an abandoned small private oil station nearby. No one has done it for a long time. There are some empty oil drums there, and there is some gasoline at the bottom of the barrel. The forensic doctor said that the body was soaked. The oil is a mixture of gasoline and cooking oil, which may have been purchased by the murderer."

Lu Junchi thought for a moment and said, "Go back and ask the nearby merchants to see if there are any unusual purchase records. Is there any other valid information?"

Zheng Bai added: "A nearby household said that one night a month ago, they saw a car parked in an open space."

A month ago, that was probably the time when the second body was thrown away.

"Can they recall a specific time?"

"It's just that I remember it was a Friday. I think it's better to push the time together with the forensic report."

The words of several people were here, when Wu Jian He Wei ran over, his face full of excitement: "Marine Corps, we have scanned several sets of clear fingerprints on the barrel of No. 1."

Hearing this news, everyone's spirits were a little excited for a while, and having fingerprints meant that they were one step closer to finding the murderer.
