Chapter 245: Eager to try

Whether it is a dismemberment case, a corpse burning case, or a skeleton case, all cases that use forensic anthropology require that the source of the corpse be found.

That is, the key question of "who is he" is the basis for solving such cases.

Ordinary grassroots forensic doctors, like doctors in grassroots hospitals, basically rely on instruments and equipment to make identifications.

Of course, high-end forensic doctors do not start boiling water right away.

Normally, DNA is run once, and fingerprints are tried. If there are none, look for special marks such as fingerprints, medical marks such as steel plates and nails, etc.

If there are forensic doctors who can impart relevant experience, it is generally believed that ordinary people getting steel nails in regular hospitals is the most effective proof of identity.

Steel nails cause little damage and are highly concealed. After being killed, forensic doctors can find the marks by just looking around, but the murderer is easily overlooked because of the lack of equipment and the separation of flesh and bones.

The problem with steel plates and prostheses is the same, with poor concealment and larger surgeries.

Tattoos or scars are even less concealed. If the murderer is more serious, he will probably cut them off separately. Moreover, they cannot be used for positive search.

Dental records are very useful in the United States, but the effect is average in China, because there is no unified database and it is impossible to search forward.

Therefore, in China, dental records can be used for confirmation, but it is still difficult to find someone through teeth and accomplish the task of who he is.

The steel plates on the head are usually numbered and not easy to be found. If you are lucky, they can also withstand a blunt attack from the killer.

The risk is that the head is easy to be taken away by someone, just like the first scattered body that was found. The skull cannot be found no matter how hard you look for it. Most of them were dealt with separately by the murderer.

——The dismemberer always likes to deal with the head separately, and some often bury it in their own home, like a kind of obsession common to the East and the West.

In general, grassroots forensic doctors mainly use these three tricks in the identification of corpse sources.

If you want to add an extra trick, it is the things around the corpse.

The clothes and objects that the deceased wore before his death, and now, the garbage dumped with the deceased.

If it is judged by the standards of current cases, the value of these garbage is very small.

But for the backlog of cases, the pitiful information is also information.

The first thing that Jiang Yuan pulled out was some packaging bags and beverage bottles.

Wang Lan said: "I'll record the time."

"Okay." Jiang Yuan handed these garbage piles that were easy to mark with time to Wang Lan.

At the same time, he also separated some organic matter and put some things that can still be distinguished, such as fish bones, pig bones, etc., aside.

Theoretically, if there are uncooked bones, it is possible to extract DNA. As for what use it has, it depends on the situation. At least, DNA is one-to-one evidence with high accuracy, and it is still very valuable.

In addition to these non-degradable garbage and some wet garbage, some textiles and paper were also separated by Jiang Yuan.

These things can also be used to prove the source of the body. Not necessarily time, maybe location.

If we can determine which clothes or papers came from which trash can, it will be easier to find the missing or dead people around.

Of course, all these premises are that the garbage and the corpse came in the same wave.

If not...

Then we can only continue to analyze the corpse. Forensic anthropology yyds!

The forensic doctors who were around would usually do similar work to Jiang Yuan, but seeing that Jiang Yuan did it quickly and well, and the classification was also very clear, like an old hand who had been doing garbage classification for many years, everyone naturally helped.

Anyway, it was about sorting garbage, and no one wanted to grab this job.

As for how to analyze garbage specifically, everyone also has some experience.

In fact, most forensic doctors have some expertise other than corpses.

For example, most forensic doctors have some fashion sensitivity. Because you have to write a report, and in the report, you have to describe the clothes of the corpse in detail.

The dead people in the jurisdiction include both working people who are dressed simply and working people who are dressed fashionably. Dark round-neck shawl, sleeveless, waisted, hooded hip skirt, and the like.

As long as enough fashion people die, even the most straightforward forensic doctor can become a little fashion expert.

It can be imagined that the forensic doctors in Paris and Milan must have strong insights into fashion.

If they work long enough, they may be able to write some works such as fashion death examination.

Niu Forensic Doctor is very good at analyzing paper.

The word "good" is not very accurate. The accurate description should be that he is particularly familiar with the types and preparation of paper.

Niu Forensic Doctor is particularly familiar with household paper, that is, paper towels, tissues, facial tissues, toilet paper and the like.

This is mainly because he used to work in an area with weak public security and an industrial structure that is particularly biased towards the offline entertainment industry. He often fished out paper towels from wastebaskets and examined semen stains.

He has done a lot. Whether it is GB/T 20808-2011 tissue paper or GB/T 20810-2018 toilet paper, you can tell at a glance.

Common materials, such as virgin wood pulp, virgin pulp, pure wood pulp and mixed pulp, or more special bamboo pulp, are also easy to distinguish.

For some common brands, Niu Forensic Doctor can tell a lot by touching and smelling.

Of course, as an inevitable derivative knowledge, Niu Forensic Doctor can also tell a lot of information based on the smell of rice green liquid.

For example, the smell of heather or chestnut flowers circulated in the market is superficial from the perspective of forensic medicine.

Not to mention that these two flowers are not common, it is the same as not saying anything. The reality is that the smell of rice green liquid is different for different people in different states.

For example, the smell is not, which belongs to impaired prostate function.

The smell is particularly strong, which may be caused by not having sex for a long time.

The fishy smell may be caused by inflammation.

Musky or fishy smell is also common, and it is likely to be a dietary problem.

If you want to use common items to describe its smell, French perfume is probably more appropriate, especially when the concentration is high. Many French perfumes have similar smells.

At this moment, Niu Forensic Doctor took the initiative to stand in front of the pile of papers.

Everyone has been working as a forensic doctor in the local area for many years, and they are familiar with each other. Some forensic doctors are good at something, and they will ask for advice if they need it.

Naturally, no one will compete with the forensic doctor Niu for the right to use the paper.

What Jiang Yuan paid the most attention to were a few small jewelry.

They were not very valuable jewelry. Judging from the material, they were probably made of copper, glass, or colored glaze. There were a pair of earrings, a necklace, and a ring in total.

Based on Jiang Yuan's experience of rummaging through garbage just now, the owners of this wave of garbage had a conservative consumption pattern.

For example, the fish bones they ate were from hairtail, and the materials of the clothes they wore were mainly chemical fiber and cotton. Judging from the packaging bags of snacks and beverages, the prices were not very high, and many of them were products of unknown small factories.

In this case, the discarded jewelry in sets was a bit abrupt.

Of course, it is also possible that it has nothing to do with this case, but Jiang Yuan still paid more attention to it. After a brief inspection, it was packed in an evidence bag.

Several forensic doctors were at the scene, sorting out about two tons of garbage, which took several hours.

The excavation on the other side was also progressing rapidly, and the mine was dug nearly 10 meters deeper.

The light conditions at this time were already very poor, and everyone hurriedly transported the things that felt useful to the top of the mine, which almost ended today's excavation.

The mine had been dug quite deep, and it would be too dangerous to do the night shift excavation.

Xu Taining was in control of the situation at the scene. Jiang Yuan went to report and said, "I'm going to Qinghe City tonight to see the situation of the body."

Xu Taining nodded with some appreciation.

He stood on the top of the mine today, watching the work below. After all, no matter how complicated the surrounding search was, it was ultimately for clues.

The body was currently the "evidence" that could bring the most clues.

And Jiang Yuan's work attitude and ability also fell into Xu Taining's eyes.

Compared with other forensic doctors he had worked with, Xu Taining saw more advantages and stronger physical strength, which could be said to be a rare excellence.

Of course, Xu Taining would not say these words, but nodded warmly and said, "Take care of yourself and don't get too tired."

"Yes." Jiang Yuan didn't know if he heard it, and after getting permission, he immediately followed the car down the mountain.

It takes two hours to get from Zifeng Town to Qinghe City.

After taking a nap on the way, and then going to the funeral home in Qinghe City, after getting off the car, it felt like a lifetime ago.

The sound of the excavator was gone, the ubiquitous buzzing voices were gone, and the anxious mood seemed to be soothed by the tranquility of the funeral home.

At the tip of the nose, there was the smell of the mountains with a hint of fireworks, the fresh fragrance of pine trees, and the smell of burnt yellow paper.

The family members of the deceased who were quietly walking in the distance, each of them used different customs to pay tribute to the deceased, but only quietness and silence were the common standards.

Jiang Yuan suddenly felt comfortable all over, as if bathing in a hot spring, and the fatigue of the body was being eliminated.

"Let's go, finish looking at the bodies early and go back to rest early." Forensic Doctor Niu jumped out of the car.

He was also exhausted today. He followed Jiang Yuan out. Rather than coming to see the autopsy, it was better to say that he was sent here to rest.

Because of Xu Taining, forensic experts from the provincial department have come to Qinghe City to help. Forensic Doctor Niu and others have no intention of doing the autopsy themselves.

Jiang Yuan has LV3 forensic anthropology, which is also the level of provincial experts. He felt that he would be helpful, so he insisted on coming to see it.

Dissection room.

The smell filled the nasal cavity, and the ventilation fan was spinning desperately but it was useless.

The first two bodies were already on the dissection table.

The scattered limbs were pieced together as much as possible, but they still looked like broken toys.

However, thinking about the fact that they were human beings before they died, stomach acid was easy to surge.

Jiang Yuan changed into a white coat and went in. His eyes fell on the corpses that were waxed.

Corpses that were waxed usually only appear in water or moist soil. If the soil is too dry, it will form a mummy-like corpse.

Both belong to the category of preserved corpses, and they seem to have more flesh and skin than the final white bones.

But when you really see the corpse, you will feel that the skeletonized corpse is more friendly.

And the corpse wax corpse, or mummified corpse, is actually suitable for wrapping with cloth strips.

Corpse wax, as the name suggests, is the part of the corpse that becomes like wax.

The main thing that changed was the fat tissue of the corpse. It started to change from the limbs, face and buttocks.

However, compared with the wax figures in the wax museum, the grayish white color of corpse wax has a much higher horror index.

From another angle, after seeing the corpse wax and then looking at the wax figures in the wax museum, the horror index hit a new high.

"Forensic Doctor Zhai." Forensic Doctor Niu first greeted the forensic experts from the provincial department.

Forensic Doctor Zhai is a thin old man with a dull look in his eyes.

He is the provincial version of Wang Lan, and also the upgraded version of Wang Lan. However, unlike Wang Lan, who runs around the city as a forensic doctor of the municipal bureau, Forensic Doctor Zhai's work is more paper work, that is, reviewing forensic reports from various places, scar identification and other textual work.

Only for particularly large cases will Forensic Doctor Zhai come over.

When he saw Jiang Yuan and Forensic Doctor Niu, he didn't say anything and let the two of them look at it themselves.

Jiang Yuan was not polite either, so he started to check from top to bottom.

The broken bones of the corpse all have matching points, indicating that there is no missing bone.

In the few places where the knife was used, forensic doctor Zhai handled it neatly.

Forensic doctor Niu looked at it for a while and then lost interest.

Looking at this dissected corpse, it is a comprehensive crushing strength. He would rather read the autopsy report.

Jiang Yuan's emotions are similar to his, but he is eager to try.
