Chapter 227 Black Plastic Bag
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 period of active decay and has a tendency to develop into later stages of decay."
The corpse has been arranged in a large shape on the autopsy table. Wang Changjiang is checking the decay of the corpse. Shen Yan was taking notes on the side.
The heavy rain outside showed no sign of stopping, but instead became heavier and heavier.
With the efforts of everyone, 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 are still conducting final inspections on the bank of Bailan River, while Wang Changjiang and Shen Yan are doing preliminary body inspections.
The first judgment 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 begins with the initial fresh corpse. As time goes by, the external environment changes, and the internal environment of the corpse is also constantly changing.
Fresh corpse is 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 other strange species that can reproduce in corpses to the point of being visible to the naked eye.
For corpses in this time 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 the body when it died may be preserved forever.
In deserts and Gobi areas where the temperature is high and the climate is extremely dry and rainless, corpses may gradually dry out and form mummies.
This has nothing to do with the condition of the corpse, it is mainly due to the influence of the external environment.
The target corpse is currently in the third stage of corpse decomposition.
The two important stages of fresh corpse and expanded corpse have been passed.
Active decay has appeared directly, and the body has entered the advanced stage of active decay.
The so-called active decay does not mean that the corpse has become active again or can move.
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 corpse stains on the exposed arms or face."
Wang Changjiang continued to inspect, and Shen Yan carefully recorded the autopsy.
Wang Changjiang did not conduct further inspection of the body for the time being. He only made a judgment on the general condition of the body 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 your height, arm length and other basic data."
"Okay."
While Wang Changjiang was taking Shen Yanzi to do a basic surface examination of the body, Liu Guodong and Lu Chuan were still soaking in the rain outside 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 point where the body was found, and radiated to the three surrounding areas to conduct surveys.
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 in charge of the direction to the west, which was already more than a hundred meters away.
With such a long distance, we can only use walkie-talkies to communicate in heavy rain.
Wow, wow, wow.
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 the search to the west of the body, Liu Guodong was responsible for the search to the east of the body, and Yang Sen and Lao Bai were responsible for the search to the south of the body, in a fan pattern. search. The two cooperated because their search area was larger than that of Lu Chuan and Liu Guodong.
“Not found.”
It was 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.
Bang!
The plastic bag was rolled up and fell far away.
Huh?
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 curtain. .
“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 although 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, a black plastic bag was touched casually 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 people’s 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 it possible that he could destroy the evidence?
People in the investigation office where he works and even the criminal police detachment where he works believe in 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 grabbed it casually with my hand. As a result, my glove was pierced by the sharp object inside, 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.
So, when Yang Sen discovered the black plastic bag for the first time, he kicked it with his toes instead of touching it with his hands.
The shoes Yang Sen wore were explosion-proof shoes issued by criminal police. They were of very good quality and could not be penetrated by ordinary punctures.
Carefully breaking a branch, Yang Sen punctured the black plastic bag.
Paji.
Objects in plastic bags fell into standing water.
Yang Sen took a closer look and his pupils dilated!
"Old Bai! Come quickly!"
