Chapter 67: Worried

The speedboat was driving laboriously on the Taihe River. Google Search Reading

Two criminal police officers, with safety ropes buckled around their waists and holding the speedboat, searched the river surface visually as much as they could.

The thunderstorm made visibility very low, with a maximum distance of 20 meters, which was dangerous and inefficient.

But because they saw a body, and it was half a body, they had to search the Taihe River no matter how difficult or hard it was.

The worse the weather conditions were, the more the criminal police team dared not relax. When the wind and sea were calm tomorrow, what would happen if the body was damaged or even lost?

As long as this murder case was not solved, there would be nothing to talk about for all members of the criminal police team in terms of work performance or political achievements this year.

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

He also knew that the probability of success in the search was very low, but solving a case was like this. You did a lot of things with a low probability of success, and it was the continuous accumulation of these things that eventually brought you success.

For the murder case, the only thing Huang Qiangmin could do was to seize every opportunity and make additional investments.

Snap!

A flash of lightning flashed across the sky, illuminating the surging river, and in an instant, the surroundings became increasingly dark.

…

Funeral home.

Jiang Yuan put on a gas mask before entering the autopsy 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, the only half corpse was gray and white, like the color of water mixed with milk.

The skin of the corpse was wrinkled, and the broken part of the waist was pale white, and the turned flesh emitted a special reflection.

Seeing Jiang Yuan coming in, Wu Jun looked up and said, "Didn't you study forensic anthropology some time ago? Now it's time to put your knowledge into practice."

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

Compared to his ability in forensic pathology, Jiang Yuan was already somewhat confident in forensic anthropology. He stood opposite Wu Jun and said, "Then I will do the dissection?"

"Let me do it first. Today's... this half corpse is still a bit difficult." Wu Jun himself was a little worried when looking at the half corpse in front of him, and naturally he was not confident that Jiang Yuan would do it directly.

It's not like an ordinary autopsy, where the knowledge of forensic pathology is used to solve the problem of "how did he die".

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

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 answering multiple-choice questions, while forensic anthropology is about answering big questions.

Forensic doctors have to analyze the information of the corpse step by step, and then answer the following basic questions:

Is this a person?

Man or woman?

What race or ethnicity?

How old is he?

What is his height, weight, and appearance?

What are his characteristics?

Who is he (she)?

If you are facing a living person, many of these questions are not problems at all. There are many ways to answer them.

But when facing a corpse, it is not that simple.

Wu Jun still cleaned the corpse step by step, made records, and finally pushed the portable X-ray machine over to take an X-ray of the lower half of the corpse.

"Looks like a relatively young male." Wu Jun inserted the X-ray into the light box in front of him, pointed at the position of the pelvis, sighed, and asked Jiang Yuan casually, "If you are only given this X-ray of the pelvis, how do you judge the gender?"

"As for the pelvis, the male pelvis is narrower and higher. The female pelvis is wider and shorter. The upper opening of the male pelvis is heart-shaped, while the female one is round or oval. In addition, the angle of the pubic arch is relatively small in males, perhaps up to 70 degrees, while the female one is 90 to 100 degrees..." Jiang Yuan spoke quickly and confidently.

The pelvis is the easiest way to judge the gender, and there are many points for judgment. To be honest, it is simpler and more accurate than using the head - the professional term is called skull judgment. Of course, this is for forensic doctors.

Wu Jun was quite satisfied with Jiang Yuan's answer, and then 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 body, so we use the pelvic bones to determine it. Assisted by long bones." Jiang Yuan has the skill of LV3 forensic anthropology, but if he is asked to preside over this autopsy, to determine the age of the body and other information, he must also take an X-ray. Or just take off all the meat on the body 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 is that only the lower half of the body is left, and the best bones to determine age are wrist bones and metacarpal bones, followed by clavicle and sternum, then pelvis, and finally long bones of limbs.

As for the nameless body in front of him, only the pelvis and limbs have been found, and the formula can only be applied by the difference in the medullary cavity.

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

"Hmm..." Wu Jun was stunned, did not say anything, and silently lowered his head to calculate by himself.

After a long while, Wu Jun raised his head, but did not tell the result. He said, "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, which is exactly 1.69 meters, 1.7 meters tall."

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

After doing this, plus the weight of half of the body, the things that can be directly inferred are basically inferred - male, 23 to 25 years old, height 170 cm, weight 130 catties...

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

However, it is enough for Wu Jun to look at Jiang Yuan with new eyes.

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

Jiang Yuan said shyly: "It is also borrowed... from various forces."

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

The initial worry has obviously disappeared.
