National Forensic Doctor

Jiang Yuan currently masters lv3 forensic anthropology and lv3 forensic clinical science.

Compared with forensic doctors of the same level, his ability has one advantage, that is, his knowledge system is extremely complete.

It's something within the scope of Forensic Anthropology lv3, he just knows it. It is knowledge within the scope of Forensic Clinical Science lv3, and he does not fall behind at all.

This is actually very buggy.

In other words, if a set of papers were issued based on the level of Forensic Anthropology lv3, Jiang Yuan could basically get 100 points in the answer.

But the reality is that most people, even expert forensic doctors, are actually a bit partial.

For example, Zhang Fengtian, Shannan Province's own 2nd level forensic doctor, may have a lv3 level of forensic anthropology, but if he is asked to take the lv2 paper, he will definitely get full marks. If he takes the lv3 paper, he may get 80 points, or Like 90 points.

There are always some special details, relatively unpopular or unpopular knowledge, which he has never studied or researched in detail.

This actually has no impact on daily work.

There is never only one path to criminal cases. In many cases, in the eyes of some people, there is only one clue, or there is no clue at all, but in the eyes of others, there may be multiple clues.

Just like an ordinary criminal policeman, when he arrives at a crime scene, he looks for DNA, fingerprints, surveillance cameras, and mobile phones. If that doesn't work, he looks for witnesses. Only a very small number of people can pay attention to the footprints and notice the shape of the blood instead of the blood. Blood itself is very rare in this era.

But for Jiang Yuan, these are all targets within his range. If he chooses any weak link, he can make a breakthrough.

In other words, the criminal suspect needs to pay attention to all these links and achieve a considerable degree of concealment to be able to escape punishment.

Similarly, for forensic doctor Zhang Fengtian of Shannan Province 2. He has many technical methods, but it does not mean that he needs to master all relevant knowledge - especially niche knowledge such as bone shrinkage rate, which has no clear conclusion. Even if he immediately starts to search papers and focus, call for consultation, etc. Wait, I don’t have a few days to figure it out.

As for which shrinkage rate is more suitable in the end, we can still only have a rough idea and cannot draw an accurate conclusion.

In other words, even if Zhang Fengtian started to make up for his shortcomings in knowledge based on the bone-burning shrinkage rate, first of all, he would be delayed for several days. Secondly, the conclusions he drew were still probabilistic, which meant that there was still the possibility of making mistakes.

Similar to Jiang Yuan, in this case, Yu Wenshu has to make the final decision and be the person in charge.

Even so, he could only finally give the victim's possible age, gender and height...

As a long-established forensic doctor, Zhang Fengtian is probably unwilling to take this path.

Jiang Yuan didn't care.

He is somewhat famous now, but he doesn't have the baggage of an idol yet, and he shouldn't have the baggage of an idol.

Sitting in the corner of the conference room, Jiang Yuan first measured each bone fragment with a ruler.

The shrinkage rate is just above one or two percentage points. It would be too bad if there was an error using the previously measured data.

Jiang Yuan measured it several times himself, recorded it, and then analyzed the degree of carbonization or porcelain of each bone fragment.

The carbonization temperature is 800 degrees and the porcelain temperature is 1000 degrees. However, these two values ​​​​are both higher than the level of existing literature and the level of ordinary civilian furnaces.

Jiang Yuan sketched on the straight surface for a moment and estimated a value of 17% for the porcelain bone fragment.

Then, a value of 15% was estimated for the carbonized bone fragments.

By doing this back calculation, you can get data such as the length and width of the fresh bone fragments.

Then apply the regression equation to get the height of the deceased.

As for gender, it depends on several characteristics.

To sum up, in this series of calculations, there must be three valuations. If it is slightly skewed, the final results may be very different.

Jiang Yuan understands Zhang Fengtian's conservatism more and more, but if you are afraid of making mistakes when doing a case, you can't do it.

Those who do criminal cases spend most of their time on trial and error, just like those who watch surveillance or check fingerprints. They always find mistakes and dead ends time and time again, and then they will choose other more difficult paths to go on.

The same goes for forensic anthropology.

If you make a mistake, try again.

Despite this, Jiang Yuan still worked very carefully to reduce errors as much as possible.

…

Everyone else in the conference room could see Jiang Yuan's working status.

At this time, the 513 case was basically over, and everyone had nothing else to do, so they had to study this current case individually.

Those who are good at making ppts will feel more comfortable. No matter how little evidence there is in the case, it will not affect their ability to make ppts.

The police officer who really had nothing to do went straight out to roll iron.

The conditions in Changyang City Bureau are better. There is a gym in the office building. Exercise and even personal training are free of charge, as long as people go there.

Jiang Yuan turned over the burned bone fragments and looked at them.

On his notebook, the values ​​were gradually listed:

Gender: Female.

Height: 165-172 cm.

Age: 22-25 years old.

By the time Jiang Yuan wrote the last item, there was almost no one in the conference room.

"Go back to the guest house and rest." Jiang Yuan edited a text message and sent it to the detachment leader Yu Wenshu. Call Wei Zhenguo again.

Wei Zhenguo rubbed his eyes, looked at his watch, and said with a smile: "It's past dinner time, I fell asleep?"

"I didn't snore." Jiang Yuan comforted him.

"Have you found out the bones?" Wei Zhenguo saw that Jiang Yuan had put away the evidence box.

Jiang Yuan nodded and said: "I don't know if it will be useful. Let's look back at the feedback from the front line."

"You don't like it?" Wei Zhenguo was so familiar with Jiang Yuan that he could easily guess part of his thoughts.

Jiang Yuan nodded slightly and said: "Although it is an active case, it has been 15 days since the case was discovered. It also takes time to burn the body. If it is burned to this level, it may take several days."

"So, you are looking for someone who disappeared 20 days ago?"

"Yeah. At least." Jiang Yuan nodded. This information is still too little, although it is extremely troublesome to obtain.

Jiang Yuan left the police station, and Yu Wenshu's text message was also returned. It was just a short "good" word, which was not redundant.

Jiang Yuan glanced at Wei Zhenguo and said, "Go back and rest. We'll see the results of the investigation tomorrow."

The next day.

Jiang Yuan, Wei Zhenguo and others returned to the unit after eating and drinking. They saw a group of people playing and playing in front of the detachment building, and there were things jumping around.

When we got closer, we were sure that the one jumping up and down was a lion dancing, and opposite the lion was Yu Wenshu.

"Jiang Yuan, come here." Yu Wenshu waved Jiang Yuan over.

Jiang Yuan: "What's the matter?"

"This is the lion dance dressed up by Ruan Sijing's family." Yu Wenshu said: "Every year during festivals, especially during the Spring Festival, his family would lead the lion dance team to perform everywhere. Ruan Sijing's case was solved, and he The family came directly with the lion head.”

Jiang Yuan hesitated for a moment and said, "The case has not been decided yet."

Yu Wen wrote: "For many people, knowing who it is is enough."

In a daze, the lion rushed forward and shook his head towards Jiang Yuan.

Jiang Yuan unconsciously reached out and touched the lion's head.

The lion's head stopped quietly and allowed Jiang Yuan to stroke it.
