No matter if it's a dismemberment case, a cremation case, or a case of skeletal remains, the key to solving the case is to use forensic anthropology to find the source of the body.
The key question of "who is he" is the basis for solving such cases.
Ordinary grassroots forensic doctors, like doctors in grassroots hospitals, mainly rely on instruments and equipment for identification.
Of course, high-end forensic doctors don't just jump into action right away.
Normally, DNA is tested, fingerprints are attempted to be taken, and if those don't work, they look for special markings such as fingerprints, medical markings like steel plates and screws.
If a forensic doctor can impart relevant experience, it is generally believed that for ordinary people, getting steel plates and screws at a regular hospital is the most effective form of identification.
The damage from steel plates and screws is minimal, and they are highly concealable. After being killed, a forensic doctor can easily find the markings, and because the killer lacks equipment and there is flesh and bone in the way, it's easy to overlook.
The problem with steel plates and prosthetics is that they are less concealable, and the surgery is more extensive.
Tattoos or scars are even less concealable, and if the killer is careful, they will probably be removed. And they cannot be used for positive searches.
Dental records are very useful in the United States, but their effectiveness in China is average, mainly because there is no unified database for positive searches.
So, in China, dental records can be used for confirmation, but it's still quite difficult to use dental records to accomplish the task of identifying a person.
On the other hand, steel plates in the head usually have numbers and are not easily discovered. If you're lucky, they can even withstand a blunt weapon attack by the killer.
The risk is that the head is easily taken away, just like the first scattered body that was discovered, and no matter how hard you look, the skull can't be found. Most likely, the killer handled it separately.
--Dismemberers always like to handle the head separately, and some even bury it in their own homes, as if it's some kind of universal madness.
Overall, the main methods for grassroots forensic doctors to identify the source of the body are these three.
If you want to add an extra move, it's the things around the body.
The clothes the deceased was wearing, the items they used, and now, the trash dumped with the deceased.
If you look at it from the perspective of the current case, the value of this trash is very small.
But for cold cases, even the smallest information is still information.
The first things Jiang Yuan pulled out were some plastic bags and beverage bottles.
Wang Lan said, "I'll keep track of the time."
"Okay." Jiang Yuan handed these piles of trash with time markings to Wang Lan.
At the same time, he also separated some organic matter, and set aside some identifiable things like fish bones, pig bones, etc.
In theory, if there are uncooked bones, it's still possible to extract DNA. As for its usefulness, it depends on the situation, but at the very least, DNA is direct evidence, highly accurate, and still valuable.
In addition to these non-degradable trash items, some wet trash, textiles, and paper were also separately separated by Jiang Yuan.
These things can also be used to prove the origin of the body. Not necessarily the time, but perhaps the location.
If it can be determined which clothes or paper came from which trash can, then finding the missing or deceased people around it will become easier.
Of course, all of these premises are based on the trash and the body coming together.
If not...
Then you can only continue to analyze the body. Forensic anthropology is awesome!
The forensic doctors surrounding him usually do similar work to what Jiang Yuan is doing, but seeing Jiang Yuan work so quickly and efficiently, and with such clear categorization, it's as if he's an expert in trash classification, so everyone naturally starts to assist.
Anyway, it's just the business of sorting trash, and no one wants to take over that job.
As for how to analyze the trash specifically, everyone has their own insights.
In fact, most forensic doctors have some expertise outside of dealing with bodies.
For example, most forensic doctors have a bit of fashion sensitivity. Because you have to write reports, and in the reports, you have to describe the deceased's clothing in detail.
In the jurisdiction, there are not only laborers dressed plainly, but also laborers dressed in fashion. Like dark-colored round-necked shawls, sleeveless waist-cinching hooded dresses, and so on.
As long as enough fashionistas die, even the most straightforward forensic doctor can become a fashionista.
It's easy to imagine that forensic doctors in Paris and Milan must have strong insights into fashion.
If you do it long enough, you might even be able to write a book on fashionable deaths or something.
Niu, the forensic doctor, is very good at analyzing paper.
Using the word "good" isn't very accurate, a more accurate description would be that he is particularly familiar with the types and preparations of paper.The forensic doctor, Niu, is particularly familiar with daily paper products, such as tissues, napkins, facial tissues, and toilet paper.
This is mainly because he used to work in an area with weak public security and an industrial structure that was particularly biased towards offline entertainment. He would often fish out tissues from waste paper to inspect for bloodstains and the like.
After doing this for a long time, he could tell at a glance whether it was tissue paper according to GB/T20808-2011, or toilet paper according to GB/T20810-2018.
Common materials, such as virgin wood pulp, virgin pulp, pure wood pulp, and mixed pulp, or more special ones like bamboo pulp, were also easy to distinguish.
Niu, the forensic doctor, could also discern many common brands by touch and smell.
Of course, as an inevitable derivative knowledge, Niu, the forensic doctor, could also discern quite a bit of information based on the taste of rice water.
For example, the taste of the widely circulated stone nan flower or chestnut flower is superficial from the perspective of a forensic doctor.
Not to mention that these two kinds of flowers are not common, and the reality is that the taste of rice water is also different for different people in different states.
For example, if it has no taste, it indicates prostate function damage.
If the taste is particularly strong, it may not have been done for a long time.
A fishy smell may be caused by inflammation.
The smell of decay or fishy smell is also common, and it is probably due to dietary problems.
To describe its taste with common items, French perfume would probably be more appropriate, especially when the concentration is high. Many French perfumes have similar flavors.
At this moment, Niu, the forensic doctor, took the initiative to stand in front of the paper pile.
All the forensic doctors had been working in the local area for many years, and they were familiar with each other to a certain extent. Some forensic doctors had specific specialties and would consult others when needed.
Naturally, no one would argue with Niu, the forensic doctor, over the right to the paper.
What caught Jiang Yuan's attention the most were several small pieces of jewelry.
They were not very valuable jewelry. Judging by the material, they were probably copper or glass, or something similar. There was a pair of earrings, a necklace, and a ring in total.
Based on Jiang Yuan's experience of just searching through the garbage, the owners of this wave of garbage had a conservative consumption pattern.
For example, the fish bones they ate were from hairtail, and the clothes they wore were mainly made of chemical fiber and cotton. Judging from the packaging of snacks and drinks, the prices were not very high, and many of them were products from unknown small factories.
In this situation, the complete set of discarded jewelry seemed a bit out of place.
Of course, it was also possible that it had nothing to do with this case, but Jiang Yuan still paid more attention to it. After a brief inspection, he put them in an evidence bag.
Several forensic doctors at the scene had classified about two tons of garbage, which took several hours.
On the other side, the excavation was also progressing rapidly, and the mine had been re-excavated to nearly 10 meters.
The lighting conditions at this time were already very poor, and everyone hurriedly transported the things that seemed useful to the top of the mine, and it was almost the end of today's excavation.
The mine had been dug quite deep, and it would be too dangerous to continue the night shift excavation.
The situation at the scene was under Xu Taining's control. Jiang Yuan reported and said, "I'm going to Qinghe City tonight to see the situation of the body."
Xu Taining nodded slightly in appreciation.
He was standing at the top of the mine today, watching the work below. After all, no matter how complicated the search around was, it was ultimately for the purpose of obtaining clues.
The body was currently the "physical evidence" that could bring the most clues.
Xu Taining also observed Jiang Yuan's work attitude and ability.
Compared to other forensic doctors he had worked with, Xu Taining saw more advantages and stronger physical strength in Jiang Yuan, which could be said to be exceptionally outstanding.
Of course, Xu Taining would not say these things, he just nodded warmly and said, "Take care of yourself and don't overwork."
"Yes." Jiang Yuan didn't know if he had heard correctly, but he got permission and immediately followed the car down the mountain.
It takes two hours from Zifeng Town to Qinghe City.
After sleeping on the way, Jiang Yuan arrived at the funeral home in Qinghe City. After getting off the car, he suddenly felt as if he had traveled to another world.
The sound of the excavator was gone, the ubiquitous chattering was gone, and the restless emotions seemed to have been smoothed out by the tranquility of the funeral home.
There was a slightly smoky rural smell and the fresh scent of pine trees, as well as the burnt smell of yellow paper.
The relatives of the deceased who were quietly approaching from a distance were each performing different customs to mourn the deceased, but quiet and silence were the common standards.
Jiang Yuan suddenly felt comfortable all over, as if bathing in a hot spring, and all the fatigue in his body was being eliminated.
"Let's go. The sooner we finish looking at the body, the sooner we can go back and rest," Niu, the forensic doctor, jumped out of the car.He was exhausted today, following Jiang Yuan out not so much to observe the autopsy of the body, but rather to take a rest.
Due to Xu Taining's involvement, forensic experts from the provincial department had already come to assist in Qinghe City. Forensic experts like Niu and others no longer had the desire to perform the autopsy themselves.
Jiang Yuan, with his LV3 forensic anthropology and being at the level of a provincial expert, insisted on coming over because he felt he could contribute.
Autopsy room.
The smell filled the nostrils, and the ventilation fan's frantic spinning was futile.
The first two bodies had already been laid out on the autopsy table.
Scattered limbs were pieced together as best as possible, but they still looked like broken toys.
However, thinking about what kind of people they were in life made one's stomach acid churn easily.
Jiang Yuan changed into his white lab coat and entered, his gaze immediately falling upon the body that had undergone saponification.
Bodies that undergo saponification usually appear in water or in moist soil. If the soil is too dry, it will form a mummified dry corpse instead.
Both are types of preserved bodies, and compared to the eventual bare white bones, they seem to retain more of a fleshly feel.
But it's only upon seeing the bodies that one realizes that skeletal remains are more pleasant.
Saponified bodies or mummies are actually better wrapped in cloth.
Saponification, as the name implies, is when parts of the body become wax-like.
The change primarily affects the body's fatty tissues, starting from the limbs, face, and arms.

But compared to the wax figures in a wax museum, the common gray-white color of saponification is much more terrifying.
From another perspective, after seeing saponification, the wax figures in a wax museum become even more horrifying.
"Dr. Zhai," Niu, the forensic expert, greeted the expert from the provincial department first.
Dr. Zhai was a gaunt little old man with a somewhat dull look in his eyes.
He was the provincial department's version of Wang Lan, and an upgraded version at that. However, unlike Wang Lan, who as a city bureau forensic expert had to run around the city, Dr. Zhai's work was more on paper, such as reviewing forensic reports from various places, and doing textual work like injury identification.
Only for particularly big cases would Dr. Zhai be called over.
Upon seeing Jiang Yuan and Niu, he didn't speak, just letting the two of them look for themselves.
Jiang Yuan didn't stand on ceremony and started examining from top to bottom on his own.
The broken bones of the body all had matching points, indicating that no bones were missing.
The few cuts made by Dr. Zhai were also clean and precise.
Niu lost interest after watching for a while.
Seeing such autopsied bodies, with an overwhelming display of skill, he would rather go read the autopsy report.
Jiang Yuan's mood had something in common with his, but he was eager to try.
