Chapter 641: Successive Deaths

With Liu Jinghui responsible for arranging the investigation direction, Jiang Yuan returned to the autopsy room.

There are still many things he can do now, but time is a bit insufficient.

First of all, Skull Reconstruction is still a super-model level forensic technology. Of course, its technical requirements and difficulty are also super-model, and the time it takes is even more so. Not to mention doing Skull Reconstruction for three corpses, even if it's just for one corpse, it would take one or two months.

Two months is the normal time. One month or less means working overtime, and constantly opening temporary skills during key stages.

As for this case, Jiang Yuan has also started to do Skull Reconstruction, but he didn't say it with great fanfare. The current scale of the special task force has risen to almost three detachments, with a scale of over three hundred people. With so many people, they can't all wait for his Skull Reconstruction to be done.

In addition to Skull Reconstruction, anthropology has always been a high-end killer skill. Jiang Yuan also wants to use this to break through, but one has to say, the four corpses discovered so far are all young people, which means that the traces of time left on their bones are very shallow, so shallow that occupational diseases haven't even come to the body.

If a person has no genetic diseases and hasn't encountered huge trauma like a car accident during the growth process, and is young and hasn't worked yet and tends to lie flat, then his bones will be white and bright, brand new, as ordinary and ordinary as when they just left the factory, new and beautiful, and it is difficult to find traces of breakthrough.

This is like sheep bones. If you boil two small sheep at a time, and the bones after eating are mixed together, it is very difficult to distinguish which is which.

Jiang Yuan moved a chair, sat at the front of the autopsy table, looked at the four corpses in front of him, and fell into deep thought.

The fourth corpse is still a male, so the victim has become two men and two women, and even the murderer's sexual orientation cannot be guessed.

Or, is the murderer not killing for the purpose of sex at all, and using social software to hook up is just a scam? The purpose is to select suitable victims?

If it is from this angle, another psychological analyst should speculate on the murderer's sexual dysfunction, or what kind of blow he received at that time...

Jiang Yuan shook his head. His experience is not enough to deal with this proposition, so he should focus his attention on the corpse itself.

The ages of the four victims are not large, all under 30 years old. The second corpse has fractures, and the knees also have wear, but none of them are serious enough to be called by name.

There is a huge problem here, which is that they all come from other places, and it is even possible that they come from foreign countries, like Mike. If the scope cannot be delineated, even if some anthropological characteristics are determined, it is still difficult to find the specific identity of the corpse.

This can be said to be the limitation of forensic anthropology. It is a collection of various conditions, but it is not like fingerprints or DNA, which can point to a unique person.

"Let's re-sort it out." Jiang Yuan jumped off the chair and decided to start again, studying the bones again.

When in doubt, redrawing is also a solution.

This look was another two days.

Afternoon.

Liu Jinghui came to the autopsy center to communicate with Jiang Yuan, and saw that Jiang Yuan was already studying insects.

"How is it? Any new discoveries?" Liu Jinghui was still a bit expectant.

"Not yet. I want to re-determine the time of death to see if I can get more clues." Jiang Yuan's skill in identifying the time of death is extremely high, and with a temporary +1 skill, maybe there will be a breakthrough.

He considered it this way, but as for clues, he didn't get any for the time being.

"What about you? Any new news?" Jiang Yuan asked.

Liu Jinghui smiled and said, "Didn't we send people to the victim's residence to see two days ago? The one in Shanghai, there is something, but not much."

"Oh, what did you find?" Jiang Yuan didn't go to see it, mainly because the criminal science center of the Zhengguang Bureau has on-site investigation with a very high technical level, at least at the LV3 level, and it is not guaranteed that there will be LV4, then it will be on par with Jiang Yuan. In this case, he doesn't need to force himself to go out in person.

Liu Jinghui said: "The victim's house is rented in Wutong District, which is the essence of Puxi, Shanghai. The rent is very expensive, 60,000 yuan a month, and the decoration is very good. During the two years or more that he has been missing, his parents have been paying the rent, although they used the company's money."

"Benefits of a Fortune 500 company?"

"Personal benefits of a Fortune 500 executive, I guess." Liu Jinghui didn't go deep into this topic and continued: "A lot of people's DNA was taken at the scene. His home also hoarded a large number of condoms and other adult products. Looking at the visits and videos, this Li Mai should be a playboy, and, he is a two-way plug, hey... back again."

Jiang Yuan knew what he meant. Since Li Mai is a two-way plug, it means that the murderer may still be a sex-oriented murder, and the investigation clues have returned to the starting point.

"Li Haochen is already pondering writing a psychological profile of the murderer." Liu Jinghui said the main reason for coming today.

Jiang Yuan couldn't help but look at Liu Jinghui and asked, "Is it effective?"

"It's not out yet, but it's basically the set of childhood trauma and bedwetting since childhood." Although Liu Jinghui is good at reasoning, he doesn't believe in psychological profiling much, and he didn't give too much respect in his words.

Jiang Yuan recalled Li Haochen's state, smiled, and gradually restrained his smile.

In other words, the investigation in the past two days still has no clues.

"The technical investigation side is also doing screening. This cost is also very high. I hope to find the identities of the other two victims."

Four victims, now it is determined that there are two, one man and one woman, but there are not many commonalities that can be found from the two, let alone involving the murderer.

"I have a discovery here, which can be used as a reference." Jiang Yuan took a notebook out of the drawer.

Liu Jinghui took out his notebook and pen directly and said, "You say, I'll write it down."

"It's not that serious." Jiang Yuan waved his hand and said, "I found it when identifying the time of death of the corpse. The time of death of these three corpses is obviously different, especially the second corpse and the third corpse. Although they have already become bones, it can still be seen that the degree of weathering of their bones has a certain difference. If the time of death is not far apart, there will not be such an obvious difference."

Liu Jinghui was refreshed: "The time of death of the three corpses is obviously different? How big is the difference?"

"The second one died first. About two weeks after death, the first one died, and then the third one, about two weeks after the first one died." Jiang Yuan paused and said, "The generation of insects also has problems. I actually found the reason from the abnormal generation of insects."

"In other words, after the murderer killed the second one, he didn't dig a pit to bury it, waited for about two weeks, waited for the first one, killed again, still didn't dig a pit to bury it, waited for the third one to come, killed it, and then buried them together? Where did he put the corpses?"

"Cannot be determined. It is very likely that they were exposed in the wilderness." Jiang Yuan didn't figure it out either, only saying, "Some insect eggs and maggots, as well as the adult stage, need a ground environment. The insect system of the three corpses is very chaotic. Looking at it carefully, it at least shows that they were not buried together at the same time and in the same place."

"Throw them on the ground first, and then bury the bones and other things together in the soil later?" Liu Jinghui couldn't help shaking his head: "This workload is very large, right? Won't it leave traces on the ground?"

"Maybe it left, but after more than two years, it can't be seen." Jiang Yuan introduced at the same time: "Placed in a hot surface environment, a corpse can become bones in 14 days."

Liu Jinghui asked: "What about the smell? And it might be seen by people."

"Maybe." Jiang Yuan shook his head. Regarding this part, he hadn't figured it out yet, or rather, there were other oddities.

"In this way, we still have to find a first scene of corpse abandonment?" Liu Jinghui believed Jiang Yuan's judgment on the spot. If it were someone else, hearing such an outrageous technical conclusion, he would have to argue for a period of time.

Liu Jinghui skipped this step and thought directly based on this.

This time, Liu Jinghui thought for a long time and took out his portable tablet computer, constantly flipping through the photos of the scene.

Watching and watching, Liu Jinghui's eyes stayed on a photo of a sewage pond and said: "We have carpet-searched this wasteland many times, but only these few sewage pits have never been carefully explored from beginning to end." ===== CHAPTER 642 =====
