Chapter 29 Dinner Together
Lu Chuan studied the human skeleton when he was in college.
But just for general understanding.
This subject is a required subject for forensic medicine. The current investigation is just for a general understanding.
The information rewarded by the system this time gave Lu Chuan a deep understanding of the structure and characteristics of human bones.
Such as the number of bones.
A normal adult has 206 bones, 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.
Some even 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 brittle bone in each joint.
This is key to bone growth, but as we age, brittle bones will slowly become smaller and disappear.
At this time, height will stop growing.
But there are also people whose brittle bones have not disappeared, but have calcified into ordinary bones.
This is equivalent to having an extra bone.
There is even a saying that in medicine, the difference between children and adults is as big as the difference between humans and chimpanzees.
Even from a medical perspective, the two are not the same species.
In the identification and analysis of skeletons, it is not just the number of bones that is relevant.
Different skeletons have different formation times, skeletalization speeds, and degrees under different conditions.
How to determine the physical 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 within the intermediate skeleton identification and analysis skills.
It can be said that Lu Chuan, who has obtained the intermediate skeleton 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, etc.
There's even forensic entomology.
Normal people basically don’t understand this. Why does forensic medicine have a branch of entomology?
This involves the issue of determining the time of death of the corpse.
Generally speaking, the time of death of a corpse can be judged by the degree of rigor mortis and the color of the corpse spots.
But this is not accurate and can only be used for temporary judgment on site.
Forensic doctors must determine the time of death of a corpse based on the surface condition of the corpse and the temperature of the internal organs, degree of decay, degree of blood coagulation, etc. after autopsy.
But for highly decomposed corpses, rigor mortis has disappeared, body spots have dissipated, and venous corruption has even occurred.
At this time, the corpse table can only determine the approximate number of days since the corpse died, but cannot obtain the exact time.
That’s where forensic entomology comes in handy.
After the human body decays, various bacteria are nourished in the body, slowly producing maggots and even hatching into corpse flies.
Forensic entomology can more accurately determine the time of death by studying the growth cycles of insects in corpses.
Skeletal identification and analysis is a very partial subject, usually included in forensic anthropology.
Remembering this, a figure flashed in Lu Chuan's mind.
When we were extracting fingerprints from the deceased in the forensic autopsy room yesterday, we made an agreement to treat Senior Shen Yan to dinner tonight.
Whether it is forensic medicine or field investigation, what we basically do is preliminary work.
Regardless of whether the case is solved or not, the work pressure of the two cannot be said to be small, but it is still a little easier than ordinary criminal police officers.
After all, if you are really busy, an all-nighter is enough.
Just like an oiran and an ordinary girl, although the essence of the work they do is the same, the treatment and the degree of pretentiousness are different.
But before the dinner date, Lu Chuan had to go home and catch up on his sleep.
I stayed up all night yesterday and was a little tired.
As for the follow-up of the case, the person has been arrested, and all that is left is to fix the evidence and organize the materials. Wang Song's case will most likely result in the death penalty.
So every detail of the case must be taken care of very carefully.
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 Zhang Wen murder case was solved, fifty or sixty people from three or four units came to talk to all the criminal police officers handling the case.
Lu Chuan, as the investigating detective who provided important clues, was naturally among them and was the focus of attention.
At that time, seven or eight waves of people bombed Luchuan continuously for a day.
Lu Chuan gets a headache just thinking about it now.
But this is also a normal process.
In the review of death penalty cases, all participants must bear responsibility.
If problems are not discovered and rectified during this process, then if they are discovered during a review ten years later, it may not be as simple as cross-examination.
All personnel in the entire chain must be punished, and there may even be more serious punishments.
After scanning 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 struggling.
No way, he is the person in charge of the current survey office, so he has to go to all meetings.
Lu Chuan wanted to replace him, but he wasn't qualified enough.
As for the on-site survey report, it was completed in the early morning.
This case, compared to Zhang Wen’s murder case, actually has more details exposed.
Sun Jun from the first group and Ren Qiang from the second group have actually discovered some clues.
The murderer Wang Song was also among the people under focused observation.
However, the footprints and fingerprints extracted by Lu Chuan and the others on the electric car completely locked Wang Song.
With these two irrefutable evidences, Wang Song has no room for quibbles.
In fact, this was indeed the case. After seeing his fingerprints, Wang Song completely collapsed.
What he couldn’t understand was how his fingerprints could still be found when the car had been soaked in water for three days?
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 responded instantly.
"Detective Lu wants to treat us, so we must give him face. Where are we going?"
"Senior, please stop making fun of me. What do you want to eat tonight?"
Lu Chuan really didn't think he was any good.
Without the system, he is just an ordinary graduate.
At most, they are graduates who have a lifetime of memories and are reborn.
"The case summary meeting was held this afternoon, and Captain Qin greatly praised you."
"Oh... I really don't know about this. I went home to catch up on my sleep during the day... "
Shen Yan sent a sour emoticon: "A murder case... you are the only ones who dare to go back to sleep now..."
Lu Chuan didn't think there was anything wrong. The work was done. If he didn't go home to catch up on his sleep, what was the use of working as a foreigner in the workplace.
"Senior, what do you want to eat tonight? It's almost time to get off work, let's go!"
"Don't call me Senior, I feel like I'm old, just call me Shen Yan... "
"As for food... I heard from Chen Lu from the agency that a new health hot pot restaurant has opened on Youhao Road. Let's go try it?"
Lu Chuan made an OK gesture.
Hot pot is good, the beauty can eat vegetables, and he can eat meat.
Gentlemen, please vote, recommend, comment, and read...
