Chapter 229: Time of Death
What Shen Yan said makes a lot of sense.
Most people wear clothes, and the price of inner and outer clothes should be about the same level.
Or, people who value the outer senses more than the inner senses.
The level of the outer garment is the same as the level of the underwear, or higher is in line with the thinking logic of most people.
The clothes on the deceased were somewhat special.
"Of course, some people pay special attention to the quality of their underwear, and it's possible that they don't care about their outer clothes, but I don't think that's how the dead are."
Shen Yan approached the chest of the corpse and gestured to the size of the deceased's bust.
"Although the corpse has begun to decompose to a high degree, it has also happened to pass the process of the giant view, and the size of the corpse is now relatively close to the real body of the deceased before his death."
"The underwear on the deceased's body is the size of a D cup, but the size of the corpse is ...... It should be a B cup, and to be more precise, you need to measure the data, but it will definitely not exceed C, and it will not be D."
Not to mention the level of underwear price, the size is not appropriate, this possibility is indeed not large.
Therefore, Shen Yan felt that the clothes on the corpse, or at least the underwear, were not the deceased.
This is the benefit of a combination of in-situ and forensic examinations.
The complementarity between different majors often has unexpected effects.
Liu Guodong is preparing the relevant survey records, and they will be sent to Qin Yong next.
Of course, whether it is an on-site investigation or a forensic doctor, what is provided is only a judgment based on reality, and does not carry the speculation that was discussed by a few people just now.
This is followed by an autopsy to determine the exact time of death of the deceased.
The cause of death, from the current point of view, should be the puncture of the left chest, resulting in heart damage and death from excessive blood loss.
But this is only a first judgment based on the superficial scars of the corpse.
The determination of the final cause of death of the corpse depends on the autopsy.
For example, the deceased was strangled to death, but the murderer may also falsify the wounds in order to cover up the true cause of the deceased's death.
In most cases, if the victim has just died, such forged injuries are relatively easy to judge in the eyes of the forensic doctor and the insect.
But the current corpse has reached the stage of active decaying corpse.
The zombie has long since disappeared, and the corpse spots don't know when they have already dissipated.
The surface skin of the corpse is now almost completely broken, and the internal organs are supposed to be in a state of high decay.
Coupled with the soaking of the river and the washing of the rain, many traces are no longer recognizable to the naked eye.
"Time of Death...... It's not easy."
Shen Yan was in charge of the autopsy this time, and Wang Changjiang was in charge of recording.
Shen Yan nodded: "The corpse is highly decomposed, and it has been soaked in the river again...... Combined with the current temperature in Haizhou City...... A month?"
"Let's cut it first, and then see how rotten the entrails are."
Forensic medicine is very different from a normal doctor.
When the surgeon performs the surgery, he or she must make sure that the incision can be sutured again and that there is no damage.
But forensics are different.
After the incision, it is sewn together, but the contents do not have to be left intact.
Comparatively speaking, it is still much worse in terms of finesse.
When Shen Yan was about to use the knife, Wang Changjiang looked at Liu Guodong, who was about to close the stall.
"Lao Liu, do you want to stay for a while?"
Wang Changjiang's words were obviously a joke, and the examination of the surface of the corpse just now included a part of the forensic examination and a part of the current investigation.
But the follow-up dissection has nothing to do with the current survey.
According to the normal process, the physical evidence collected should be analyzed.
It's just that this time it's more fortunate that the crime scene can be determined to be definitely not the first crime scene.
So, except for the sharp knife with a scabbard inside the black plastic bag found by Janssen, the rest was the clothes on the deceased's body.
Some physical evidence such as strangled fingerprints, hair, or dander, which could normally be collected at the scene of the crime, was not available this time.
"The rest of you are busy, I don't want to stay here any longer."
After all, it doesn't smell good.
He and Wang Changjiang have their own experience, and they don't wear gas masks like Lu Chuan and Shen Yan at all.
"Master, I want to stay for a while."
Liu Guodong was about to turn around and leave, but Lu Chuan did not turn around, but stared at the corpse on the dissection table, slightly distracted.
"Huh?"
The back is the autopsy, Lu Chuan still wants to see it?
Liu Guodong knew that Lu Chuan was proficient in the identification and analysis of bones that only forensic doctors would normally have, but this corpse was still far from the definition of bones.
Lu Chuan followed Liu Guodong for more than half a year, so that Liu Guodong had a deeper understanding of his apprentices.
Usually deal with people and things, not informal, but steady and thoughtful in work.
Lu Chuan had also inspected the corpse with Shen Yan before, so it was definitely not for Shen Yan to stay.
As for watching the lively......
What is there to see in the dissection of a cadaver.
Unless you don't want to eat.
Besides, Lu Chuan is not this character.
So, he said that he wanted to stay, there must be something.
With a slight turn in his mind, Liu Guodong figured it out.
"Xiao Lu, is there something wrong?"
Lu Chuan nodded.
Since he obtained the intermediate corpse insect egg identification and analysis ability rewarded by the system, Lu Chuan has not had the opportunity to verify this skill.
Now that I finally have a carrion corpse, I should be able to help somewhat.
At the very least, it shouldn't be too difficult to determine the time of death of the corpse.
But Lu Chuan naturally doesn't say anything about the system.
Lu Chuan walked up to Shen Yan and picked up a chubby maggot that had fallen on the dissecting table.
"When I was in college, I did some research on parasitic eggs."
The maggot in Lu Chuan's hand was a fly maggot.
In general, the common maggot is the larval state of a fly.
Flies lay eggs on decaying corpses, and after the eggs have developed, they are the maggots we commonly see.
Of course, there are many species of maggots, a headless larva to be exact.
In addition to flies, there are many species of Diptera insects whose larvae are in the state of maggots.
It's just that, in everyday life, the larvae of flies are the most common.
The maggot larvae in Lu Chuan's hand are about three millimeters, which is already close to the state of an adult.
"Ordinary corpse fly larvae can grow up to about two centimeters, and then turn into pupae and hatch into flies."
"The larva in my hand, about 1.5 centimeters, is still two or three days away from maturity."
"Most fly larvae should take 2 to 3 weeks from egg laying to emergence, depending on the outside temperature and humidity."
"But it's uncertain whether this larva is the first generation of larvae produced by the decomposition of corpses."
"However, it can be verified by experiments, so that the time of death can be determined by the growth cycle of the larvae."
Lu Chuan probably explained the reason why he stayed.
