National Forensic Doctor

Chapter 666 Mixed race

Different races have different physical characteristics. This is absolutely correct knowledge until the wind of political correctness blows.

A very typical example is "Carabelli's tubercle", which refers to the common enamel tubercle on the lingual surface of the first molar near the neck of the maxilla of Caucasians. The Karabelli tubercle is actually the accessory tooth of the molar. Pointed, the second and third molars of some white people are also distributed, but it is extremely rare for people of color.

The unique tooth shape of yellow people is the spade-shaped incisor, which has a 90% occurrence rate. Similarly, among white and black people, the occurrence probability of this tooth shape is extremely low.

Many people go to the hospital for bone grinding, cheekbone reduction surgery, etc. In fact, the purpose is to make differences in facial features through bone changes.

The so-called advanced face's wide eye distance, high cheekbones, square chin, prominent brow peaks, etc. are also reflected in the bones.

Jiang Yuan only gained some understanding in this aspect after mastering LV3's skull restoration technique. After all, the coverage of this skill is not limited to domestic countries. Many countries in the world, especially immigrant countries like the United States, actively or passively study the racial characteristics of different races and mixed-race people.

In contrast, even if domestic forensic doctors have studied the racial characteristics of human races, they have rarely dealt with the characteristics of mixed races. Even the forensic doctors in the capital, such as the old comrade Zeng Lianrong, are half-informed and very confused. I do not understand.

"Mixed blood, what kind of mixed blood is it?" Zeng Lianrong couldn't help but asked curiously.

"Mixed Asian and European." Jiang Yuan could only give a rough idea.

However, one has probably greatly narrowed the scope, which can be said to be a major breakthrough. There are a lot of foreigners in the capital, and there are also a lot of mixed-race people, but if you count Asian-European mixed-races alone, the total number will definitely be small. The most important thing is that the police don't need to find all the Asian-European mixed-races, they only need to find the missing persons. .

As for the fact that the victim's family did not report the crime, the problem is even greater. If no corresponding missing person can be found, this itself is actually another clue.

No matter how calm Zeng Lianrong was, he couldn't delay at this time. He took off his gloves first, then changed them again, and asked: "Forensic Doctor Jiang, could you please tell me."

He believed that he was responsible for this time's anatomy and conclusion, and if there was a major breakthrough, he should report it as soon as possible. But before that, he had to make sure that Jiang Yuan's judgment was correct, or at least reasonable.

Zeng Lianrong felt a little strange. Normally, he wouldn't have such a problem. If his subordinates discovered any details or had any conclusive evidence, Zeng Lianrong would go over and take a look and he would know whether their judgment was correct or whether it was true or biased.

But today’s situation is completely different. He’s okay with mixed race, and he’s okay with forensic anthropology, but does mixed-race forensic anthropology go beyond the scope?

However, Jiang Yuan was very familiar with Zeng Lianrong's problem. He had encountered it countless times.

Jiang Yuan turned around.

He put on a smile that convinced all sentient beings and said: "There are many ways to judge. I use the skull as the main basis, mainly the following three points, the canine tooth fossa, the zygomatic bone marginal process, and the lateral swelling of the piriform foramen."

The three positions Jiang Yuan mentioned are basically on the front face, and they are all standard academic terms.

Zeng Lianrong was stunned and quickly entered the role. He picked up the skull on the dissecting table and said while looking at it: "If I remember correctly, these three positions are all non-measurable traits."

Jiang Yuan nodded and said: "Yes, but there are also some indicators that can be used, or just use them like this."

The so-called non-measured shape is described through anthropological observation and is also an important means of anthropological research. Simply put, it is based on seeing. Qualitative but not quantitative.

This is actually very easy to understand. Anyone does not need to receive any theoretical knowledge or anthropological explanations. If you put a white person and a yellow person in front of you, you can easily distinguish the difference between the two.

In fact, if the person is still alive, if a mixed-race person stands in front of ordinary people, it is not certain that he can be distinguished, but there is still a high possibility.

Of course, this assumption does not make much sense. It is like judging men and women by the pelvis. If people are still alive, this thing should not be a subject at all. There are many people who can make more detailed classifications.

However, in the final analysis, practice makes perfect.

Zeng Lianrong frowned and said: "In terms of non-measurement traits, how accurate is it? I mean, how can you tell that you are a mixed race?"

Jiang Yuan thought about this question for a while, and then said: "If you look at it a lot, it is relatively easy to see. For example, the lateral part of the piriform foramen is swollen. Europeans will be taller. The same is true for skull No. 3, but its other These two features are more inclined to the Asian face shape. If you make a Frankfurt plane, it will probably be easier to see."

In fact, as soon as the words "non-measured traits" came out, the topic changed from scientific to authoritative.

Indicators that cannot be quantified are just like antique appraisals. Whoever is the best has the final say.

But from another perspective, if no one messes up, the accuracy of this thing is guaranteed, and there is room for discussion among peers. Generally speaking, it is difficult to deceive people.

As for the Frankfurt plane, if this word appears in the forensic community, it is high-end.

Zeng Lianrong frowned again: "Have you ever studied skull reconstruction?"

The young man from the Beijing Bureau next to him quickly said: "Team Jiang has used restored skulls to solve cases before."

Everyone's eyes changed.

Zeng Lianrong had to show a surprised expression, and quickly recalled the knowledge he had learned. When he found that it was not correct, he said: "I didn't expect... Since you know about skull recovery, then I will do what you said." Report."

Skull Restoration Technique is an amazing technique that can restore the appearance of the deceased using a skull. Zeng Lianrong didn't know it, but he knew he couldn't learn it. In this case, when it came to looking at the face of the corpse, Obviously we need to listen to Jiang Yuan's opinion.

Moreover, speaking at the high end, judging a detailed race through a skull is originally a special skill of anthropological observation. This thing was not invented to solve crimes. From its inception to its current position, its main application field is paleoanthropology.

Most of the human fossils dug out from the ground are incomplete, and the complete ones will basically be shown on TV. Therefore, anthropology experts can only rely on non-measured trait observation methods for research and screening. Their daily life is often to hold a skull, see the eternity, and then write an entire doctoral thesis.

Jiang Yuan and Zeng Lianrong understood, but nodded politely, and briefly explained a few words, saying: "You can report it first and see what Team Tao has to say."

Zeng Lianrong took off his gloves again and went out to make a phone call.

Jiang Yuan resumed work, and everyone else lowered their heads, working silently while communicating crazily with their eyes.

Tao Lu was speechless when he received the call.

He found three corpses at once. He couldn't tolerate such a big case. But one of the three corpses was a mixed race, and he really couldn't stand it.

This case was already very sensitive, and Tao Lu and Bureau Fan handled it very hard, but because of the victim's racial status, the case was probably going to be a big deal.

Tao Lu had nothing to say, so he continued to report. The specific business must still be his, but the superiors must be informed of the situation.

Reporting all the way, and searching through the missing people, according to more information given by Jiang Yuan and Zeng Lianrong, they quickly identified one person - Mike, Chinese name Li Mai, American nationality, both parents are in China Executives working in foreign-owned enterprises.

When this set of information came out, Director Fan felt it was a bit troublesome. It's nothing else, just solve the case that needs to be solved, but if you want to block the news, it becomes difficult.

Tao Lu could only dispatch manpower and ask himself immediately to prepare to solve the case within a time limit.

At this time, all the brigades scattered outside were about to be recalled, and Tao Lu called each one to inform and persuade.

When Cui Lu called Cui Qishan, Cui Lu had not yet spoken. Cui Qishan said tiredly: "Tao Zhi, have you received the news now?"

"Nonsense, of course I received it... No, what news do you have over there?" Tao Lu felt something was wrong.

Cui Qishan said: "We just found another body."

I'm going to the outpatient clinic tomorrow morning for a review of my endocrine system. I hope it's OK... You can express your emotions with monthly tickets!
