Things that solve crimes

Qin Henian had already seen that the femoral head of corpse No. 4 had collapsed in this area.

Femoral head necrosis. Qin Henian looked closely for a quarter of an hour and finally came to this conclusion. What kind of occupation can cause femoral head necrosis?

After thinking about it over a cup of tea, he didn't come to a conclusion, so he called Jiang Buyan directly.

After receiving the call, Jiang Buyan rushed to the anatomy room quickly, taking a Liu Jianghe with him.

Qin Henian found a pair of protective clothing for them, handed it to them and said, "You don't have to come over. We can also discuss it on the phone."

Jiang Buyan shook his head, "You have to see things in person to understand clearly."

"Okay." Qin Henian took the person to the dissecting table No. 4, pointed at the femoral head of the corpse, and said, "See for yourself."

The femur is the thigh bone, the largest long bone in the human body, and above it is the femoral head.

Because of its strong strength and bending resistance, ancient people would choose it as the best material for daggers thousands of years ago.

Judging from the daggers that have been unearthed, it is still very good as a dagger material.

However, I couldn't find any clues on it.

"Tell me about it." Jiang Buyan sighed.

"Femoral head necrosis." Qin Henian pointed to the upper end of the femur.

Jiang Buyan touched his chin, "If you get this disease, you usually go to the hospital. You can check the hospital's medical records."

"The age of onset of this disease is usually between 30 and 50 years old. The deceased was very young. The disease is most likely caused by occupation, but special circumstances, such as alcoholism and the use of large amounts of hormones, cannot be ruled out." Qin Henian said.

Xu Xia looked away from the bones and looked at Qin Henian, "Divers, pilots, and fishermen with a history of working in decompression chambers are all prone to this disease."

Jiang Buyan nodded slightly, "Alcoholism and hormone use should be rare among young people."

"Some athletes may also suffer from this disease." Qin Henian added.

Xu Xia, “Gymnastics.”

Jiang Buyan said, "Acrobat."

……

The two then guessed several professions, and Jiang Buyan couldn't help but say with a headache, "This murderer kills people very casually!"

The deceased Yu Li was a student. There are some clues on the skeleton No. 4, but there is little hope.

Qin Henian looked at the other corpses and asked the two of them, "How is the task force doing?"

Jiang Buyan looked like he had a headache, "There are chicken feathers everywhere."

"The source of the murder weapon is unknown, the murderer's motive is unknown, and the source of the body is unknown. How to do it and how to do it are all a problem." Speaking of this, Xu Xia also felt his head hurt.

Qin Henian also understands that the case is now shrouded in fog, and those who can join the task force will definitely be strong. Just determining a general direction requires a lot of effort.

Both of them have big heads.

The task force is also overwhelmed.

In the case of the dismemberment of seven corpses, not a day went by without calls from the leaders of the provincial and municipal bureaus and the mayor.

If a few white shirts from Jinshi hadn't called the province in person, the order to solve the case within a time limit might have been issued.

At that time, no one needed to sleep.

The first two days were spent getting familiar with the case and collecting clues. On the fourth and fifth days, there was still no movement from the task force, and everyone knew what was going on.

No clue!

Having no clues is a big problem. No matter how well you do, it won't work if you don't solve the case.

For a moment, everyone on the task force looked sad and angry. The office was like a "wonderland" every day, and there was no shortage of coffee.
