National Forensic Doctor

The beeping speedboat was driving hard on the Taihe River. Google search reading

The two detectives, with safety ropes on their waists and speedboats in their hands, searched the river as visually as possible.

The weather with thunderstorms makes the visibility very low. The distance of up to twenty meters is dangerous and inefficient.

But because we saw a corpse, and it was half a corpse, no matter how difficult or painful it was, we had to search the Taihe River.

The worse the weather conditions are, the less the criminal police team dares to relax. When the weather calms down tomorrow, what if the body is destroyed or even cannot be found because of it?

As long as this murder case remains unsolved, there will be nothing to talk about this year's work performance or political achievements for all members of the criminal police brigade.

Huang Qiangmin himself stood on the shore, with an obviously useless telescope hanging around his neck, staring at the river with all his eyesight.

He also knows that the probability of successful search is very low now, but solving a case is like this. You do a lot of things with a very low probability of success, and it is the continuous superposition of these things that finally brings you success.

Regarding the murder case, the only thing Huang Qiangmin can do is to seize every opportunity and make additional investment.

Snapped!

A bolt of lightning flashed across the horizon, illuminating the raging river. In an instant, the surrounding area became darker and darker.

…

funeral parlor.

Jiang Yuan put on a gas mask before walking into the anatomy room.

Comrade Wu Jun, the old forensic doctor, did not have such high requirements. He still wore a mask and started working.

On the stainless steel autopsy table, there was only half a corpse, which was gray and white, like the color of milk mixed with water.

The skin of the corpse was wrinkled, the broken part of the waist was pale white, and the opened flesh gave off a special reflection.

Seeing Jiang Yuan entering, Wu Jun raised his head and said, "Weren't you doing medical anthropology some time ago? Now it's time to apply what you have learned."

Jiang Yuan had previously acquired the skill of Forensic Anthropology (LV3), which he did not use for the time being, but it did urge him to read a lot of books.

Compared with his ability in forensic pathology, Jiang Yuan already had some confidence in forensic anthropology. He stood opposite Wu Jun and said, "Then I will do the autopsy?"

"I'll do it first. Today's...this half corpse is still a bit difficult." Wu Jun looked at the half corpse in front of him and was a little worried. Naturally, he didn't trust Jiang Yuan to directly operate it.

Unlike ordinary autopsy, the problem of "how to die" is solved through the knowledge of forensic pathology.

What forensic anthropology needs to do is to first find out "who is this".

To be honest, the problems that forensic anthropology has to solve are inherently more difficult than those of forensic pathology.

To describe it, forensic pathology is like doing multiple-choice questions, while forensic anthropology is about answering big questions.

Forensic doctors must analyze the corpse's information step by step, and then answer the following basic questions:

Are you a human?

Man or woman?

What race or ethnicity?

How old are you?

What is your height, weight, and appearance?

What are the characteristics?

Who is he or she?

Many of these questions would not be a problem at all if faced with a living person. There are many ways to answer this question.

But when facing a corpse, it's not that simple.

Wu Jun still cleaned the body step by step and made records. Finally, he brought a portable X-ray machine over and took X-rays of the lower half of the body.

"It looks like he is a relatively young man." Wu Jun inserted the X-ray film into the light box in front of him, clicked on the position of the pelvis, sighed again, and asked Jiang Yuan casually, "If I only gave you this pelvis X-rays, how do you tell whether they are male or female?”

"As for the pelvis, the male's pelvis is narrower and taller. The female's is wider and shorter. The upper opening of the male's pelvis is heart-shaped, while the female's is round or oval. In addition, the angle of the pubic arch , the male angle is relatively small, maybe 70 degrees, and the female angle is 90 to 100 degrees..." Jiang Yuan said quickly and with certainty.

The pelvis is the best way to judge men and women, and there are many judgment points. To put it bluntly, it is simpler and more accurate than using the head—the professional term is called the skull. Of course, for forensic scientists.

Wu Jun was quite satisfied with Jiang Yuan's answer and continued: "Next, let's use bone age to determine age. Do you know how to do this?"

"We only have the lower half of the corpse, so let's use the pelvic bones to judge. The long bones are supplemented." Jiang Yuan has LV3 forensic anthropology skills. However, if he is asked to preside over this autopsy, he must determine the age of the corpse and other information. You also need to take X-rays. Or just remove all the meat from the corpse and look directly at the bones.

As far as the current situation is concerned, it is obvious that the former is less destructive and more practical.

The only troublesome part is that only the lower half of the body is left. The best bones to judge the age are the wrist bones and metacarpal bones, followed by the clavicle and sternum, then the pelvis, and finally the long bones of the limbs.

As for the nameless corpse in front of us, only the pelvis and limbs have been found so far, and the formula can only be established based on the difference in the medullary cavity.

"23 to 25?" Jiang Yuan pressed the calculator and gave the result directly.

"Well..." Wu Jun was stunned and said nothing, silently lowering his head and doing his own calculations.

After a while, Wu Jun raised his head, without saying the result, and said again: "Calculate the height again."

Jiang Yuan pressed the calculator and said: "The total length of the femoral trochanter is 43, multiplied by a coefficient of 36 is 1015, plus 680, it is exactly 1.69 meters, and the height is 1.7 meters."

Calculating height using long bones is more accurate and simple.

And after achieving this step, plus the weight of half the corpse, what can be directly inferred is basically complete - male, 23 to 25 years old, 170 centimeters tall, 130 kilograms in weight...

The above is not enough to arrive at the ultimate question: Who is he or she?

However, it was enough for Wu Jun to look at Jiang Yuan with admiration.

"You young people learn things quickly." Wu Jun sighed.

Jiang Yuan said shyly: "I also borrowed... all kinds of power."

"Hey, when I was young, I wanted to learn, but I couldn't find a book, so I had to follow my master everywhere to dissect corpses. At that time, it was called learning through practice..." Wu Jun sighed with emotion, but handed the knife to Jiang Yuan. , said: "You come and do the dissection."

The initial worry has obviously disappeared.
