civil forensic

Chapter 67

The beeping speedboat was driving hard on the Taihe River.

Two criminal policemen, with safety ropes buckled around their waists, held the speedboat in their hands, and searched the river surface as best they could visually.

The weather with thunderstorms makes the visibility very low. The distance of up to 20 meters is dangerous and inefficient.

But because I saw a corpse, and it was half a corpse, no matter how hard it was, I had to search Taihe again.

The worse the weather conditions were, the less the criminal police brigade dared to relax.When the weather is calm tomorrow, if the body is destroyed, or even cannot be found because of it, then what should be done.

And as long as this discovered murder case is not solved, for all members of the criminal police brigade, there is nothing to talk about about their work performance or political achievements this year.

Huang Qiangmin was standing on the bank by himself, 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 such a thing. You have done many things with a low probability of success, and it is the continuous superposition of these things that finally brings you success.

Regarding the murder case, what Huang Qiangmin can do, the only thing he can do, is to seize every opportunity and invest more.

Snapped!
A flash of lightning flashed across the sky, illuminating the turbulent river, and in an instant, the surroundings became darker and darker.

……

funeral parlor.

Jiang Yuan put on the gas mask before entering the dissection room.

Comrade Wu Jun, an old forensic doctor, does not have such high requirements. He still wears a mask and starts to work.

On the stainless steel dissecting table, the only half of the corpse was gray and white, as if the color of milk had been mixed with water.

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

Seeing Jiang Yuan entered, Wu Jun looked up and said, "Didn't you read medical anthropology a while ago? Now is the time to apply what you have learned."

Jiang Yuan acquired the skills of forensic anthropology (LV3) before, and he has not used them for the time being, but he 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. Standing opposite Wu Jun, he said, "Then I'll do the dissection?"

"Let me go first. Today's... the difficulty of this half corpse is still a bit high." Wu Jun looked at the half corpse in front of him, and was a little worried, so he was naturally worried about Jiang Yuan's direct operation.

Unlike ordinary autopsies, the knowledge of forensic pathology is used to solve the problem of "how to die".

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

To be honest, the problems to be solved in forensic anthropology are inherently more difficult than those in forensic pathology.

To put it in a nutshell, forensic pathology seems to be doing multiple-choice questions, while what forensic anthropology needs to do is to answer big questions.

The forensic doctor has to analyze the information of the corpse 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 (she)?

Many of these problems are not problems at all if they are faced with a living person.There are many ways to answer it.

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

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

"It looks like a relatively young man." Wu Jun inserted the X-ray into the light box in front of him, clicked on the position of the pelvis, sighed, and asked Jiang Yuan casually, saying, "If you only give this pelvis X-ray, how do you judge a man and a woman?"

"In terms of pelvis, the shape of the male pelvis is narrower and higher. The shape of the female pelvis is wider and shorter. The upper mouth of the male pelvis is heart-shaped, and the female 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 he said it with certainty.

The pelvis is the best way to judge men and women, and there are many judgment points. Speaking of it, it is simpler and more accurate than judging with the head—the professional term is called the skull.Of course, it is for forensic doctors.

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

"We only have the lower half of the corpse, so use the pelvic bones to judge. Use the long bones as an aid." Jiang Yuan has LV3 forensic anthropology skills, but let him preside over the autopsy to judge the age of the corpse and other information. Had to take X-rays too.Or just remove all the flesh from the corpse and observe the bones directly.

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

The only troublesome part was that only the lower half of the body was left, and the bones that best judged age were the wrist bones and metacarpal bones, followed by the clavicle and sternum, the pelvis, and finally the long bones of the limbs.

As for the nameless corpse in front of him, only the pelvis and lower limbs have been found so far, and the formula can only be set by the difference of the marrow cavity.

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

"Hmm..." Wu Jun was stunned for a moment, but silently bowed his head and made his own calculations.

After a while, Wu Jun raised his head and said without saying the result, "Let's count the height again."

Jiang Yuan pressed the calculator and said: "The total length of the femoral trochanter is 43, multiplied by a coefficient of 2.36 is 1015, plus 680, it is exactly 1.6 meters nine, and the height is 1.7 meters."

Using long bones to calculate height is more accurate and simple.

And after this step, plus the weight of half of the corpse, what can be directly inferred is basically the end of the inference—male, 23 to 25 years old, 170 cm tall, 130 catties in weight...

The above is not enough to draw the ultimate question: who is he (she).

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

"You young people are quick to learn." Wu Junchang sighed.

Jiang Yuan shyly said: "It also borrowed... the strength of various parties."

"Hey, when I was young, I wanted to learn, but I couldn't find a book, so I had to follow Master to dissect corpses everywhere. At that time, it was called learning from practice..." Wu Jun sighed, but handed the knife to Jiang Yuan , Said: "You come to dissect."

The initial apprehension had obviously dissipated.
