civil forensic

Chapter 670
With Liu Jinghui in charge of arranging the direction of the investigation, Jiang Yuan returned to the dissection room.

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

First of all, skull restoration is still a forensic technology at the supermodel level. Of course, its technical requirements and difficulty are also supermodel, especially the time it takes.Not to mention performing skull restoration surgery on three corpses, it would take a month or two even to do only one corpse.

Two months is the normal time, and one month or less will require overtime work, and temporary skills will be developed continuously during critical stages.

As far as this case is concerned, Jiang Yuan has also started to do skull restoration surgery, but he did not say it out loudly. The current size of the task force has risen to almost three brigades, with 300 people or more. Well, with so many people, they can't all wait for their own skull restoration surgery to be done.

In addition to skull restoration, anthropology has always been a high-end killer skill. Jiang Yuan also wants to make a breakthrough with this, but one thing to say, the four corpses discovered so far are all young people, which means, The traces of time left on their bones are very shallow, so shallow that no occupational diseases have ever caught their bodies.

If a person does not have genetic diseases, does not encounter huge traumas such as car accidents during his growth, and is young and has not worked and tends to lie flat, then his bones will be white and brand new, as if he just left the factory At that time, it was ordinary and ordinary, new and beautiful, and it was difficult to find traces of breakthrough.

This is the same as lamb bones. If you cook two lambs at a time, the bones after eating will be mixed together, and it will be difficult to tell which is which.

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

Corpse No. [-] was still a man, so the victims now became two men and two women, and even the murderer's sexual orientation could not be guessed.

Or, the murderer didn't kill for sexual purposes at all, and the use of social software to date was just a scam?The purpose is to pick the right victim?
From this point of view, if you change to a psychoanalyst, you should guess at this time that the murderer's sexual function was damaged, or when and what kind of blow he received...

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

The four victims were all young, all under the age of 30. Corpse No. [-] had broken bones and worn knees, but none of them were serious enough to be named.

A huge problem here is that they are all from other places, maybe even 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 is arguably the limitation of forensic anthropology.It's a collection of conditions, but it's not like a fingerprint or DNA that points to a single person.

"Let's do it again." Jiang Yuan jumped off the chair and decided to start over and study the bones again.

In case of indecision, redrawing the picture is also a solution.

This look is another two days.

afternoon.

Liu Jinghui came to the anatomy 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 looking forward to it.

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

That's what he thought about, but he didn't get any clues for the time being.

"What about you? What's new?" Jiang Yuan asked.

Liu Jinghui smiled and said, "Didn't we send someone to look at the victim's house two days ago? The one in the Shanghai stock market has a few things, but not many."

"Oh, what did you find?" Jiang Yuan didn't follow to see, mainly because the criminal investigation center of the Zhengguang Bureau has a very high level of on-site investigation, at least LV3 level, if it is not complete, there will be LV4, then it will be on the same level as Jiang Yuan , in this case, there is no need for him to force himself to go out.

Liu Jinghui said: "The victim's house is rented in Wutong District, which is the best part of Shanghai Puxi. The rent is very expensive, 6 yuan a month, and the decoration is very good. He has been missing for more than two years. Pay the rent, even though it’s the company’s money.”

"The benefits of the world's top [-]?"

"The personal benefits of the top [-] executives in the world." Liu Jinghui did not go further on this topic, and continued: "Many people's DNA was obtained at the scene, and he also stocked up a large number of condoms and other adult products at home. According to interviews and videos, this Li Mai should be a playboy, moreover, it’s a two-way plug, hey...he’s 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 clues of the investigation have returned to the original point.

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

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

"I haven't figured it out yet, but it's probably the trauma of my childhood, the bed-wetting thing." Although Liu Jinghui is good at reasoning, he doesn't really believe in psychological profiling, and he doesn't give much respect in his words.

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

In other words, after two days of investigation, there were still no clues.

"The technical investigation is also conducting investigations, and the cost is also very high. I hope to find out the identities of the other two victims."

Of the four victims, two are now identified, one male and one female, but there are not many similarities that can be found from the two, let alone involving the murderer.

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

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

"It's not that serious." Jiang Yuan waved his hand and said, "When I checked the death time of the corpses, I found that the death times of the three corpses were obviously different, especially the No. [-] and No. [-] bodies. Although they are all skeletalized, it can still be seen that there is a certain difference in the degree of weathering of their bones, if the time of death is not far apart, there will not be such an obvious difference."

Liu Jinghui was shocked when he heard this: "Is there a significant difference in the death time of the three corpses? How big is the difference?"

"No. [-] died first, about two weeks after death, No. [-] died again, and then No. [-], about two weeks after No. [-] died." Jiang Yuan paused, and said: "There is also a problem with the generation of insects. I actually found the reason in reverse from the anomaly of the insect's generation line."

"That is to say, after the murderer killed No. [-], he hadn't dug a pit to bury him. He waited for about two weeks, and when No. [-] came, he shot again, but he still didn't dig a pit to bury him. He waited until No. [-] came, and killed him again." , and then buried together? Then where is his body placed?"

"I can't be sure, it's very likely that the corpses were exposed in the wilderness." Jiang Yuan didn't want to understand, but said: "The eggs, maggots, and adult stages of some insects require an above-ground environment. The insect systems of the three corpses are very chaotic. If you look at it carefully, at least it shows that they were not buried at the same time and in the same place.”

"Throw it on the ground first, and then bury the bones and the like in the soil together?" Liu Jinghui couldn't help shaking his head: "Isn't this a lot of work, won't it leave traces on the ground?"

"Maybe it's left, but it won't be obvious after more than two years." Jiang Yuan also introduced: "Put it in the hot surface environment, and a corpse can be skeletalized in 14 days."

Liu Jinghui asked: "What about the taste? It might be seen by others."

"Maybe." Jiang Yuan shook his head. He still hasn't figured out this part, or in other words, there are other strange things.

"In this way, we still need to find the first scene where the corpse was abandoned?" Liu Jinghui believed Jiang Yuan's conclusion on the spot. If it was someone else, it would take some time to argue for such an outrageous technical conclusion.

Liu Jinghui omitted this step, and directly thought on this basis.

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

Looking at it, Liu Jinghui's gaze stayed on a photo of a sewage pool, and said: "We have searched this wasteland several times with a carpet search, but these sewage pits have not been carefully searched from beginning to end. explored."
