The decay of a corpse begins the moment the heart stops beating.
In the eyes of forensic doctors, decomposed corpses can be divided into several more detailed stages.
"The corpse is in a stage of active decay and has a tendency to develop into later stages of decay."
The corpse has been arranged in a large format on the autopsy table. Wang Changjiang is checking the decomposition of the corpse, while Shen Yan is taking notes.
The heavy rain outside showed no sign of stopping, but instead became heavier and heavier.
Thanks to everyone's efforts, the body has been placed on the autopsy table of the Criminal Investigation Detachment from the bank of Bailan River.
As Lao Bai and Yang Sen said, apart from the heavy rain, the smell of rotting corpses is indeed very offensive.
Lu Chuan and Liu Guodong were still conducting final inspections on the bank of Bailan River, while Wang Changjiang and Shen Yan were doing preliminary body surface examinations.
The first thing to judge is the degree of decomposition of the body.
If Lu Chuan was in the autopsy room, he could come to the same conclusion as Wang Changjiang.
The decomposition of a corpse starts from the initial fresh corpse. As time goes by, the external environment changes, and the internal environment of the corpse is also constantly changing.
Fresh corpses are the first stage of corpse decomposition.
The freshness mentioned here is different from what we usually call fresh vegetables, fresh air, fresh pork, etc.
This kind of freshness is similar to steaming cow dung, that kind of freshness.
Generally speaking, whether it is a current investigation or a forensic doctor, what they most hope to encounter is this kind of corpse.
Fresh corpses generally don't have any weird smell.
There are no strange other species that can reproduce in corpses to the point where they can be seen by the naked eye.
For corpses in this period, it is easier to determine the time of death due to the presence of rigor mortis.
There is no fixed standard for how long the corpse should be preserved in the first stage.
This is determined by the external environment in which the body is located.
In the wild with higher temperatures and greater humidity, fresh corpses will not be stored for more than 48 hours.
But in places with extremely low temperatures, such as the polar regions, the appearance of a body when it died may be preserved forever.
In deserts and Gobi areas with high temperatures and extremely dry climate and little rain, corpses may gradually dry out and form mummies.
This has nothing to do with the condition of the corpse, but mainly the influence of the external environment.
The target corpse is currently in the third stage of corpse decomposition.
It has passed the two important stages of fresh corpse and expanded corpse.
Active decay appeared directly, and the corpse had entered the advanced stage of active decay.
The so-called active decay does not mean that the corpse becomes active again or can move.
Rather, it means that the parasitic corpse flies in the corpse have been able to move freely, break through the constraints of the skin, and can be observed by the naked eye.
"The corpse was severely decomposed, and there were no remains of corpse stains on ***'s arms and face."
Wang Changjiang continued the examination, and Shen Yan carefully made autopsy records.
Wang Changjiang did not conduct further inspection of the corpse for the time being. He only made a judgment on the general condition of the corpse through naked eye observation.
Liu Guodong had already said hello that he would wait for them to come back from Bailan River and inspect the surface of the body together.
"Xiao Shen, please measure the height, arm length and other basic data."
"OK."
While Wang Changjiang was taking Shen Yanzi to do a basic superficial examination of the corpse, Liu Guodong and Lu Chuan were still soaking in the rain outside the Bailan River.
The heavy rain became heavier and heavier, and the two of them were already soaked through.
"Master, I didn't find anything here."
The four of them, Lu Chuan, started from the center where the body was found and radiated to the three surrounding areas to investigate.
The direction of the river was the surging Bailan River. It was a vast expanse of white and there could not be anything there.
Lu Chuan was responsible for the direction to the west, and he had already walked out for a while.
More than 100 meters.
At such a long distance, communication can only be made through walkie-talkies in heavy rain.
Hua Hua Hua.
After the weak current noise passed, Liu Guodong's voice came from the intercom: "Nothing was found in the east."
"Lao Bai, Yang Sen, where are you?"
At the scene, Lu Chuan was responsible for searching the west side of the body, Liu Guodong was responsible for searching the east side of the body, and Yang Sen and Lao Bai were responsible for searching the south side of the body in a fan-shaped manner.
The two cooperated because their search area was larger than that of Lu Chuan and Liu Guodong.
"not found."
It's Lao Bai's voice.
"It rained so hard that everything was washed away."
Yang Sen's shoes were filled with water, and he kicked a black plastic bag on the ground.
boom!
The plastic bag was rolled up and thrown far away.
Um?
Is there something in here?
Yang Sen trotted over and looked at the distance to the river. It was about fifty meters away.
"What's wrong? Lao Yang? Did you find anything?"
Lao Bai was more than thirty meters away from Yang Sen. He saw the black plastic bag rolled up at Yang Sen's feet and shouted loudly through the rain.
"There seems to be something, let me take a look!"
Yang Sen shouted through the heavy rain and squatted down to check the black plastic bag that had just been kicked away by him.
Although it was raining heavily and even though his whole body was soaked, Yang Sen, who had been doing field survey for more than ten years, still had a more cautious behavior.
This can be regarded as a lesson of blood and fire.
Three years ago, a new young man from a criminal investigation detachment from another province also engaged in spot investigation.
At the murder scene, he casually touched a black plastic bag without wearing gloves.
The young man thought it was just an ordinary black plastic bag and would have nothing to do with the crime scene.
Just looking at it blocking my way, I picked it up casually and wanted to throw it away.
As a result, when I picked it up, a sharp knife fell out.
The other party was so excited that he picked up the sharp knife and shouted that he had found the key clue.
The clue is indeed crucial. The sharp knife in the black plastic bag is the murder weapon.
However, the young man also made a fatal mistake.
Since he was not wearing gloves at the time, his fingerprints were naturally left on the handle of the sharp knife.
What's even more coincidental is that except for his fingerprints, there are no other fingerprints on the murder weapon.
how to explain?
In desperation, the young man did not wear gloves according to the on-site inspection regulations and accidentally left fingerprints on the murder weapon?
Or does he have anything to do with the case and deliberately used this method to erase his careless omissions in handling the murder weapon?
In other words, is it possible that he knows the murderer and is there a possibility of destroying evidence?
People in the investigation office where he works and even the criminal police detachment where he works believe him, but will the judge believe him?
For similar cases, ministries and commissions have made special notifications.
Five years ago, there was another case.
If the case three years ago only involved the detection of a case, the case five years ago was a living life.
Five years ago, a criminal police officer from another province also found a plastic bag at the crime scene.
Looking at the bulging bag, I casually grabbed it with my hand, but the sharp object inside pierced my glove, causing serious exposure after bleeding.
It was later discovered that inside the black plastic bag were discarded needles used by the deceased for intravenous injection.
The cause of death of the other party was also due to extensive drug abuse, and he was also a carrier of a highly infectious virus.
Unfortunately, the investigating detective was eventually infected with the virus because of that exposure.
My whole life is ruined.
Therefore, when Yang Sen discovered the black plastic bag for the first time, he kicked it with his toes.
Not touching with hands.
The shoes Yang Sen wore were explosion-proof shoes issued by criminal police. They were of good quality and could not be penetrated by ordinary punctures.
Carefully breaking off a branch, Yang Sen punctured the black plastic bag.
Paji.
Objects in plastic bags dropped into standing water.
Yang Sen took a closer look and his pupils dilated!
"Old Bai! Come on!"
