Chapter 230 Time of Death
What Shen Yan said makes sense.
For most people, the price of inner and outer clothing should be about the same.
Or, there are more people who value external senses than inner senses.
The level of outerwear should be the same as that of underwear, or higher, which is in line with most people’s thinking logic.
The clothes of the deceased were somewhat special.
"Of course, some people pay special attention to the quality of their underwear, and it is possible that they don't care about their outerwear, but I don't think the deceased is like this."
Shen Yan approached the corpse's chest and gestured. The size of the deceased's chest.
"Although the corpse has begun to decay to a high degree, it has also gone through the process of giant viewing. The current size of the corpse is relatively close to the true size of the deceased during his lifetime."
"The body of the deceased The bra size is D cup, but the size of the body... should be B cup. To be more precise, you need to measure the data, but it will definitely not exceed C, let alone D. "
Let’s not talk about the price level of the underwear. The possibility that the size is not suitable is indeed very unlikely.
So, Shen Yan felt that the clothes on the corpse, or at least the underwear, did not belong to the deceased.
This is the benefit of joint inspections by current investigators and forensic doctors.
The complementarity between different majors often produces unexpected results.
Liu Guodong is preparing the relevant live survey records and will send them to Qin Yong next.
Of course, whether it is on-site investigation or forensic medicine, they only provide judgments based on reality, and will not contain the speculations made during the discussion by a few people.
The next step is to conduct an autopsy on the corpse to determine the specific time of death of the deceased.
The cause of death, from the current point of view, should be puncture of the left chest with a sharp instrument, resulting in heart damage and death from excessive blood loss.
But this is only the first judgment based on the injuries on the surface of the corpse.
The final cause of death of a corpse depends on the autopsy.
For example, the deceased was strangled, but the murderer may also have faked the injuries in order to conceal the true cause of death.
In most cases, if the victim has just died, such fake injuries are easier to judge by forensic doctors and investigators.
But the current corpse has reached the stage of active decay.
rigor mortis has long since disappeared, and the corpse spots have long since dissipated.
Now the surface skin of the corpse has been basically damaged, and the internal organs should also be in a highly decayed state.
Coupled with being soaked by river water and washed away by rain, many traces are no longer discernible to the naked eye.
"The time of death... is not easy to figure out."
Shen Yan was responsible for performing the dissection this time, and Wang Changjiang was responsible for recording.
Shen Yan nodded: "The corpse was highly decomposed and soaked in the river... combined with the current temperature in Haizhou City... a month?"
"Let's cut it first, Then look at the corruption of the internal organs.”
The profession of forensic medicine is very different from that of normal doctors.
When the doctor performs an operation, he must make sure that the suturing can be done again after the incision without causing any damage.
But forensics is different.
After incision, although it needs to be sutured, the contents inside do not need to remain intact.
In comparison, the level of precision is still much worse.
When Shen Yan was about to use the knife, Wang Changjiang looked at Liu Guodong who was about to close the stall.
"Old Liu, do you want to stay for a while?"
Wang Changjiang's words were obviously a joke. The surface examination of the body just now was part forensic and part investigation.
But the subsequent anatomy has nothing to do with the current investigation.
According to normal procedures, the physical evidence collected must be analyzed during the current investigation.
However, this time, luckily, the crime scene was definitely not the first crime scene.
So, except for the sharp knife with a scabbard in the black plastic bag that Yang Sen found, the rest were the clothes on the deceased. Some of the physical evidence of strangulation, such as fingerprints, hair or dander that can usually be collected at crime scenes, was not available this time.
"You can do the rest, I don't want to stay here any longer."
After all, the smell here is really not very good.
He and Wang Changjiang had their own experience and were not like Lu Chuan and Shen Yan who wore gas masks.
"Master, I want to stay for a while."
Liu Guodong was about to turn around and leave, but Lu Chuan did not turn around. Instead, he stared at the corpse on the autopsy table, slightly lost in thought.
“Huh?”
The dissection is coming later. Lu Chuan still wants to see it?
Liu Guodong knew that Lu Chuan was proficient in the identification and analysis of skeletons that only forensic doctors could do, but this corpse was still far from the definition of a skeleton.
Lu Chuan has followed Liu Guodong for more than half a year, allowing Liu Guodong to have a deeper understanding of his apprentice.
Normally, he is informal in dealing with people, but he is steady and thoughtful at work.
Lu Chuan had looked at and inspected the corpse with Shen Yan before, so it was definitely not because of Shen Yan that he wanted to stay.
As for watching the fun...
What's there to see in an autopsy?
Unless you don’t want to eat.
Besides, Lu Chuan is not of this character.
So, there must be something going on when he said he wanted to stay.
With a slight thought, Liu Guodong figured it out.
"Xiao Lu, is something wrong?"
Lu Chuan nodded.
Since receiving the intermediate corpse egg identification and analysis ability rewarded by the system, Lu Chuan has not had the opportunity to verify this skill.
Now we finally have a rotting corpse, which should be of some help.
At the very least, it shouldn’t be too difficult to determine the time of death of the body.
But Lu Chuan naturally wouldn't talk about the system.
Lu Chuan walked to Shen Yan and picked up a chubby maggot that splashed 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.
Generally speaking, common maggots are the larval state of flies.
Flies lay eggs on decaying corpses, and when the eggs develop, they become maggots.
Of course, there are many kinds of maggots, to be precise, they are headless larvae.
In addition to flies, there are many kinds of dipteran insects whose larvae are in the state of maggots.
However, in daily life, fly larvae are the most common.
The maggot larvae in Lu Chuan's hand were about three millimeters in size and were already close to adult status.
"General corpse fly larvae can grow up to about two centimeters, then turn into pupae and hatch into flies."
"The larvae in my hand is about 1.5 centimeters, and it is still two or three days away from maturity. "The time from egg laying to emergence of most fly larvae should vary depending on the outside temperature and humidity."
"But it is still uncertain whether the current larvae is the first generation larvae produced after the corpse decayed."
"However, it can be verified through experiments. In this case, the growth of the larvae can be analyzed cycle to determine the time of death.”
Lu Chuan finally explained the reason why he stayed.
