Criminal Investigation Notes

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

The clothes on the corpse were still wearing, that is, an ordinary t-shirt and a pair of black trousers. The shoes of the corpse were taken off, and one pair of feet was bare.

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

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

After being soaked for a period of time, the corpse became very soft, the joints seemed to have slipped out of the bone groove, and the flesh and blood had changed, like a pool of soft butter.

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

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

Under the ribs of the corpse, many knife marks can be seen, and those knife marks are densely packed, there may be more than a dozen knife marks, and there may be more in detail.

Su Hui squatted down and looked at the knife wounds. Many of the knife wounds were very close to each other, and one could see the madness and rage of the murderer.

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

In a chain of cases like this with multiple bodies, determining the time of death can help clarify the status of the case.

The little forensic doctor was probably an intern, and said falteringly: "The corpse is soaked in oil, and the general method of measuring time is useless. Just wait for Sister Jing, she should know."

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

Then she looked at the corpse on the ground calmly, and stretched out her rubber-gloved hands to press the skin and abdomen of the corpse, and some gasoline seeped out of those incisions.It appeared that gasoline had soaked the body from the inside out.

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

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

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

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

Xing Jing hummed: "Oil and water and other liquids have different properties. Oil-soaked corpses are not very common, and they haven't been written about 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 forensic doctors, that is, the food in the stomach can be well preserved by the oil, even after a long time It's not bad either, it can be used as a forensic reference."

The two masters and apprentices discussed as if there was no one else present, and Wu Jian next to him turned pale and vomited again and again.

Lu Junchi looked at Su Hui's indifferent expression, they saw the scene almost, Lu Junchi suggested: "Let's go to the other side to see?"

Su hummed.

The other site was a hundred meters away from this one, and it was an old farm.As soon as you enter, you can smell the smell of animal feces. There is a bigger oil drum here, and there are some oil stains on the ground.

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

In comparison, this No. [-] corpse is "full" than the other one, with two stab wounds on the chest.

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

Wu Jian said: "It should be that cooking oil and gasoline have been mixed."

Su Hui looked at the corpse for a while, and then suddenly asked the photographer next to him, "What did this corpse look like when it was discovered?"

The Wujian hurriedly adjusted the photo and showed it to him. It was different from the last corpse. This corpse was stuffed in an oil drum. From the surface of the oil drum, some hairs could be seen floating, and Upturned feet can be vaguely seen.

Zheng Bai squatted aside and looked at it and asked, "In this case, are we looking for a serial murderer who targeted adult men?"

Based on what he knew, Qiao Ze tried to analyze: "Serial killers have certain criteria for choosing their victims. Most serial killers target women, a few target children, and some target the elderly. Men's serial crimes are relatively rare, but there are, and many of them hunt and kill men because of their sexual orientation..."

For those murderers, a thin victim will satisfy their desire to be weak, and a strong victim, especially an adult male, will bring many variables and dangers to the murder process.

Su Hui coughed a few times, but didn't speak.

Lu Junchi looked at the scene and raised his head, "The two murders have similar knives and similar storage methods, but the dumpers may be different."

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

At the two crime scenes less than a hundred meters apart, two male corpses soaked in oil drums, the wounds were also stab wounds. No matter from which angle you look at it, it is more likely that they are an abandoned corpse. big.

"Pay attention to the oil stains on the ground here." Lu Junchi narrowed his narrow eyes slightly, and he pointed to the messy oil stains on the ground. Some of the oil spots caused by forensic transport were still wet, and it was easy to get along with those old people. to distinguish the oil marks.

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

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

"The oil barrel next to the first corpse is very clean, with only a few oil spots, but the side of this barrel is very messy, with a lot of oil stains. I suspect that the first barrel was put in the corpse first, in order to prevent the corpse from decomposing and attracting insects. There was a smell, so gasoline was poured in, and this second time, the murderer first put more than half of the barrel of oil in the barrel, and then threw the body into it."

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

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

All indications indicated that this second throwing of the corpse was much more panicked than the first time.

Su Hui coughed a few times, gave Lu Junchi an approving look, and then said in a low voice: "Let me add one more thing, the height of these two corpses is not low. Especially the second corpse, which was caused by the phenomenon of oil melting, etc. Destroyed, the deceased should have weighed between 150 and 1.3 jins during his lifetime. Even a grown man would find it very difficult to carry such a weight. The height of the oil drum was about [-] meters, and the diameter was about the same. It's very big, but it's still a bit small compared to the corpse, and it's basically impossible for the corpse to turn over in it. The first corpse was placed head down, which is relatively simple and reasonable, but the second corpse is V It is much more difficult to put in the form.”

When a normal corpse is put in, it is either curled up with the head down, or curled up with the feet down, and the buttocks are put in, which is very weird.

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 this, raised his head and asked, "Then how did this corpse go in?"

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

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

Zheng Bai thought for a moment and turned to Qiao Ze, "Try it and you will know." He hugged Qiao Ze before he could react.

Qiao Ze was picked up suddenly, and he let out a cry of fright, and reached out to grab Zheng Bai's clothes, fearing that he would be thrown away.

Zheng Bo looked down at him with a smirk: "What are you afraid of, I'm just making gestures, and I won't really throw you into the oil drum."

After speaking, he turned provocatively and walked to a place very close to the oil barrel.

Qiao Ze grasped it tightly, gritted his teeth and said, "Zheng Bai, if you dare to throw me, all the records will be yours later!"

Having said that, he was quite cooperative, trying to assume the posture of the deceased in the bucket when he was discovered, and also instructed, "Oh, you are not using the right strength, and the corpse is not sitting, it is a bit like V-shaped!"

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

The more he talked, the more difficult it was to pose. In just a short time, Zheng Bai broke out in sweat.

Zheng Bai was nearly 1.9 meters tall and muscular, while Qiao Ze was only 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 still cooperate, but the dead are dead.

When Lu Junchi saw it, he felt that this method would not work: "The No. 1.8 corpse looks like a fat man with a height of nearly [-] meters, and must be heavier than Qiao Ze. Your attempt just shows that the princess hug is not feasible. "

Zheng Bo asked: "Is it possible that when the bucket was tipped over, people were stuffed in first?"

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

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

In that posture, the deceased's hands were hanging down, as if he was supported by two people, one lifted his armpits and the other lifted his feet, and put them into the bucket.

His words made everyone suddenly enlightened.

Lu Junchi took a closer look at the splash marks beside the oil barrel, and concluded even more: "The position where I stand is 180 degrees opposite to the position where there are fewer splash marks, and this happens to be where the head and feet of the original corpse were placed. This shows that the bodies of the two people who abandoned the corpses happened to block part of the splashed oil spots."

The ground of this farm is covered with broken soil. I tried to extract the footprints for physical evidence just now, but I couldn't find a complete one after searching for a long time, but the oil marks revealed the number of people who abandoned the corpses and where they were located.

Lu Junchi looked at it and said, "One of them has small feet...maybe it's a woman."

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

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

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

The person who abandoned the corpse must have known about the murderer's murder, and the number of people involved in this matter has increased...

Only then did Zheng Bai put Qiao Ze down: "Is that a serial killer killing people? But many people participated in the body throwing? Like parents helping?"

"There are many other possibilities..." The smell inside was too bad, and the smell of gasoline made people's brains not quite turn. Su Hui coughed repeatedly when he said this.

Several people analyzed the traces that appeared at the scene of the corpse throwing. It sounds like this case is more complicated.

Lu Junchi said: "We'll wait for the results of the physical examination and forensic examination, compare the disappearance records, and first determine the identities of the two victims."

He looked at the time and said to his two subordinates, "You should search nearby first."

After leaving the corpse dumping scene, Su Hui felt that his breathing became easier. 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 Bai and Qiao Ze went together tacitly, and Lu Junchi also found an assistant policeman to ask the person who found the body first.

Su Hui looked at Wu Jian and was busy for a while, then sat aside to rest.

There is no village in front of this area, no shops in the back, it has not been demolished, it has not been sold, it is sparsely populated, and there are not many nearby residents.

It was past eleven o'clock, and the weather had warmed up a little. Su Hui was in a daze when he suddenly saw a bottle of mineral water dangling 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 it? It's still hot."

Lu Junchi sat beside him and said, "I brought it myself. When I locked the car, I put two bottles on the rear seat. After drying for a while, it warmed up and was ready to drink."

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

He didn't think that being a criminal policeman necessarily meant being exposed to wind and 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 felt that criminal police was a hard job, and being in the 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, Embarrassment, even being able to take good care of him and the people around him.

Su Hui lowered his head while drinking water and thought, Lu Junchi takes care of people meticulously, and his care will not cause any burden to people.

It's like after he moved in, Su Hui found that the house became clean, tidy, warm and organized, and he could make all kinds of tricks for his three meals a day.

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

He would remind him to get up early, to bring his umbrella.

There are always various things in his office, such as regular medicines, stationery and tools that will be used, all neatly stacked, like a treasure chest.

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

Su Hui had almost no resistance to his tenderness.

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

He couldn't 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 pressed the water bottle to his cheek, trying to cool down, only to remember that the water was warm, making his cheek even hotter.

At this moment, Qiao Ze and Zheng Bai had already returned, their heads were sweating from the heat, Lu Junchi threw two bottles of water over, the two took a few sips before talking.

Zheng Bo: "We have found the source of the oil barrels. There is a small abandoned private oil station nearby. No one has done it for a long time. There are some empty oil barrels over there, and there is still some gasoline at the bottom of the barrels. The forensic doctor said that the corpses were soaked. The oil is a mixture of gasoline and cooking oil, and maybe the cooking oil was purchased by the murderer and brought over."

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

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

A month ago, that might have been the time for body number two to be dumped.

"Can they recall a specific time?"

"It's just that I remember it was a Friday. I think it's time to push it back based on the forensic report."

Just as the few people were talking, He Wei, Wu Jian, ran over with excitement on his face: "Lu Corps Lu Corps, we have scanned several sets of clear fingerprints on the No. [-] bucket."

Hearing this news, everyone's spirits were a little lifted for a moment. With fingerprints, it meant that they were one step closer to finding the murderer.
