Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 29 Dinner Together
About human bones, Lu Chuan had studied in college.

But just for general understanding.

This subject is a compulsory subject of forensic medicine, and the current investigation is only for general understanding.

This time, the information rewarded by the system gave Lu Chuan a deep understanding of the structure and characteristics of human bones.

Like the number of bones.

There are 206 bones in a normal adult, but what about children?
The number of bones in children is 217 or 218, and there are differences in the skull and sacrum.

A child's skull and sacrum gradually merge as they grow, growing from multiple pieces into one.

Even, some have differences in the finger bones.

This is related to the mechanism of human body growth.

Between the bones of children's limbs, there is a section of brittle bone in each joint.

This is the key to bone growth, but as we age, brittle bones slowly shrink until they disappear.

At this time, the height will stop growing.

But there are also some people whose brittle bones do not disappear, but calcify into ordinary bones.

This is equivalent to an extra bone.

There is even a saying that, in medicine, children are as different from adults as humans are from chimpanzees.

Even, the two are not the same species from a medical point of view.

In the identification and analysis of bones, it is not only the number of bones that is relevant.

The formation time, ossification speed and degree of different skeletons are different under different conditions.

How to judge the body characteristics of the deceased, the cause of death, etc. based on the hardness, bone density, and surface roughness of the bones.

They are all abilities in the intermediate bone identification and analysis skills.

It can be said that Lu Chuan, who has obtained intermediate bone identification and analysis, is already a forensic doctor to a certain extent.

Of course, there are many branches of forensic medicine.

Such as forensic pathology, forensic clinical science, forensic toxicology and so on.

There's even forensic entomology.

Normal people basically don't understand this. How can there be a branch of entomology in forensic medicine?

This involves determining the time of death of the corpse.

Generally speaking, the death time of the corpse can be judged by the degree of rigor and the color of the corpse spots.

But this is not accurate and can only be used for temporary judgment on the spot.

The forensic doctor should judge the death time of the corpse based on the surface condition of the corpse and the temperature of the internal organs, the degree of corruption, and the degree of blood coagulation after dissection.

But for highly decomposed corpses, the rigor has disappeared, the plaques have dissipated, and even venous corruption has appeared.

At this time, the corpse table can only be used to judge the approximate number of days since the corpse died, but the exact time cannot be obtained.

That's where forensic entomology comes in handy.

After the human body decays, various bacteria are nourished in the body, and maggots are slowly produced, and even hatch into corpse flies.

Forensic entomology can determine the time of death more accurately by studying the insect growth cycle in the corpse.

The identification and analysis of skeletal remains is a very partial discipline among them, usually included in forensic anthropology.

Thinking of this, a figure flashed in Lu Chuan's mind.

When the fingerprints of the deceased were taken in the forensic anatomy room yesterday, it was agreed that senior sister Shen Yan would be invited to dinner tonight.

Whether it is forensic medicine or field survey, basically all the work is preliminary work.

Regardless of whether the case is solved or not, the work pressure of the two cannot be said to be light, but compared with ordinary criminal police, it is still a little easier.

After all, if you're really busy, it's almost an overnight stay.

Just like an oiran and an ordinary girl, although the essence of the job they do is the same, the treatment and the degree of pretense are different.

But before the dinner appointment, Lu Chuan had to go home to catch up on sleep.

I stayed up all night yesterday and was a little tired.

As for the follow-up of the case, the person has already been arrested, and the rest is to fix the evidence and sort out the materials.

In Wang Song's case, there is a high probability that the death penalty will be imposed.

Therefore, every detail of the case must be carefully selected.

Lu Chuan has not been in the police for a long time, but he has also experienced the review of death penalty cases.

After the case of Zhang Wen's murder was solved, five or sixty people from three or four units came to talk to all the criminal police who were handling the case.

Lu Chuan, as the current detective who provided important clues, was naturally among them, and he was the focus of attention.

At that time, seven or eight waves of people bombarded Luchuan continuously for a day.

Lu Chuan has a headache thinking about it now.

But this is also a normal process.

In the review of death penalty cases, all participants must bear the responsibility.

If the problem is not found out during this process and rectified, then if it is discovered during the review ten years later, it may not be as simple as questioning.

All personnel in the entire chain will be punished, or even more severely punished.

After sweeping a shared bicycle, Lu Chuan left the Criminal Investigation Detachment leisurely.

Lu Chuan left, Yang Sen and Lao Bai also went back, but Liu Guodong was still suffering.

There is no way, he is the person in charge of the survey office, and he has to go to meetings and so on.

Lu Chuan wants to replace him, but he is not qualified enough.

As for the survey report, it was finished in the early morning.

In this case, compared with Zhang Wen's murder case, there are actually more details exposed.

Sun Jun in the action group and Ren Qiang in the second group have actually found some clues.

The murderer, Wang Song, was also within the scope of key observation personnel.

However, the footprints and fingerprints collected by Lu Chuan and the others on the electric car completely locked Wang Song.

With these two ironclad evidence, Wang Song has no room for sophistry.

In fact, it was true. After seeing his fingerprints, Wang Song completely collapsed.

What he couldn't understand was that the car had been soaked in water for three days, how could he still find his fingerprints?
Four twenty in the afternoon.

Lu Chuan came to the Criminal Investigation Detachment again.

After sending a WeChat message to Shen Yan, the other party replied in seconds.

"Detective Lu wants to treat guests, he must show face, where are you going?"

"Senior sister, don't make fun of me. What would senior sister want to eat tonight?"

Lu Chuan really didn't think he had any gods.

Without a system, he is just an ordinary graduate.

At most, they are reborn graduates with the memory of a lifetime.

"The summary meeting of the case was held this afternoon, and Team Qin has greatly praised you."

"Oh... I really don't know, I went home to catch up on sleep during the day..."

Shen Yan sent a sour emoji: "Murder case... you guys dare to go back to sleep now..."

Lu Chuan didn't think there was anything wrong with it. After the work was done, if he didn't go home to catch up on sleep, it would be of no use to work abroad in the unit.

"Senior sister, what do you want to eat tonight, it's time to get off work, let's go!"

"Don't call me senior sister, I feel like I'm old, just call me Shen Yan..."

"As for the food... I heard from Chen Lu from the agency that there is a new hot pot on Youyou Road, let's go and try it?"

Lu Chuan sent an OK gesture.

Hot pot is good, beauties can eat vegetables, and he can eat meat.

　Gentlemen, please vote, please recommend, please comment, please follow up...
