The decomposition of the corpse begins the moment the heart stops beating.

In the eyes of forensic doctors, the decomposed corpse can be divided into more detailed stages.

"The corpse is in a period of active decay and has a tendency to develop into later decay."

The corpse on the autopsy table had been arranged in a large font, Wang Changjiang was checking the decomposition of the corpse, and Shen Yan was taking notes.

The heavy rain outside had no intention of stopping, but was getting heavier and heavier.

With the efforts of everyone, the corpse has also been placed on the autopsy table of the criminal investigation detachment from the bank of the Bailan River.

As Lao Bai and Yang Sen said, out of the heavy rain, the smell of decomposing corpses is indeed very aggressive.

Lu Chuan and Liu Guodong were also conducting a final survey on the bank of the Bailan River, where Wang Changjiang and Shen Yan were doing a preliminary autopsy.

The first thing to judge is the degree of decomposition of the corpse.

If Lu Chuan was in the dissection room, he would be able to come to the same conclusion as Wang Changjiang.

The decomposition of the corpse begins with the initial fresh decaying corpse, and as time goes by, the external environment changes, and the internal environment of the corpse is constantly changing.

Fresh corpses are the first stage of corpse decomposition.

The concepts of freshness here are different from what we usually call fresh vegetables, fresh air, fresh pork, etc.

This freshness is similar to steaming cow dung, the kind of alternative freshness.

Generally speaking, whether it is an on-site investigation or a forensic doctor, it is this kind of corpse that you most hope to encounter.

Fresh corpses, generally do not have any weird taste.

There are no other strange species that are able to reproduce inside carcasses to the point where they are visible to the naked eye.

The corpse of this time period is easier to determine the time of death because of the presence of corpse mortis.

There is no fixed standard for judging how long the corpses were preserved in the first stage.

This is determined by the external environment in which the body is located.

In the wild, where the temperature is higher and the humidity is high, fresh carcasses will not be kept for more than 48 hours.

But in places with extremely low temperatures, such as the polar regions, it is possible that the corpse will be preserved forever as it was when it died.

In deserts and Gobi areas with high temperatures and extremely dry climates and little rainfall, corpses may gradually dry and form dry corpses.

This has nothing to do with the condition of the body, but mainly external environmental influences.

The stage the target corpse is now in is the third stage of corpse decay.

It has passed the two important stages of fresh corpse and inflated corpse.

Active decomposition is a direct occurrence, and it has entered the advanced stage of active decomposing corpses.

Active decomposition does not mean that the corpse is reactivated or able to move.

Rather, it means that the parasitic flies in the corpse have been able to move freely, break through the shackles of the skin, and can be observed by the naked eye.

"The corpse is badly decomposed, and there are no corpse spots left on ***'s arms and face."

Wang Changjiang continued to check, and Shen Yan carefully made autopsy records.

Wang Changjiang did not conduct further examination of the corpse for the time being, but only made a judgment on the general condition of the corpse through visual observation.

Liu Guodong had already said hello and wanted to wait for them to come back from the Bailan River and inspect the surface of the corpse together.

"Xiao Shen, you can measure basic data such as height and arm length."

"Okay."

When Wang Changjiang took Shen Yanzi to do a surface examination of the basic corpse, Liu Guodong and Lu Chuan were still drenched in the rain outside the Bailan River.

The rain was getting heavier and heavier, and the two of them were already drenched.

"Master, I haven't found anything here."

Lu Chuan's four people, starting from the center point where the body was found, radiated to three aspects around to investigate.

The direction of the river is the rushing Bailan River, which is so white that there can be no thing.

Lu Chuan is in charge of the direction of the west, which will have gone out one

More than 100 meters.

At such a long distance, in the heavy rain can only be contacted by walkie-talkie.

Whoa, whoa, whoa.

After the faint noise of electricity, Liu Guodong's voice came from the walkie-talkie: "I haven't found it in the east."

"Lao Bai, Yang Sen, what about your side?"

At the scene, Lu Chuan was responsible for the search in the west direction of the body, Liu Guodong was in charge of the search in the east direction of the body, and Yang Sen and Lao Bai were in charge of the south direction of the body, which was searched in a fan area.

The two cooperated, because their search area was larger than that of Lu Chuan and Liu Guodong.

"Didn't find it."

It's Lao Bai's voice.

"It's raining so hard that everything is gone."

Janssen's shoes were filled with water, and he kicked a black plastic bag on the ground wetly.

Bang!

The plastic bag was rolled up and fell into the distance.

Well?

Something's here?

Yang Sen trotted over and looked at the distance from the river, which was about fifty meters away.

"What's wrong? Old Yang? Did you find anything?"

Lao Bai was more than thirty meters away from Yang Sen, and when he saw the black plastic bag rolled up under Yang Sen's feet, he shouted loudly through the rain curtain.

"Something seems to be there, I'll take a look!"

Yang Sen shouted through the heavy rain, crouched down to inspect the black plastic bag he had just kicked away.

Although it was raining heavily and his whole body was soaked, Yang Sen, who had been dry for more than ten years, still had a more cautious behavior habit.

This is also a lesson of blood and fire.

Three years ago, a young man from a criminal investigation detachment in another province was also engaged in field investigation.

At the scene of the homicide, he did not wear gloves and casually touched a black plastic bag.

The young man thought it was just an ordinary black plastic bag, and it would not have much to do with the crime scene.

It's just looking at the way of yourself, picking it up at random and wanting to throw it away.

As a result, a sharp knife fell out of it when he picked it up.

The other party was excited, and actually picked up the sharp knife, shouting that he had found a key clue.

The clue is indeed quite crucial, and the sharp knife in the black plastic bag is the murder weapon.

However, the lad also made a fatal mistake.

Since he was not wearing gloves at the time, his fingerprints naturally remained on the handle of the sharp knife.

What's more coincidental is that there are no other people's fingerprints on the murder weapon except his fingerprints.

How to explain it?

The young man did not wear gloves in accordance with the current investigation procedures in a hurry, and inadvertently left fingerprints on the murder weapon?

Or does he have anything to do with the case, deliberately using this way to erase his careless handling of the murder weapon?

In other words, is it possible for him to know the murderer, and there is a possibility of destroying the evidence?

The 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?

In similar cases, the ministry has made a special report.

Five years ago, there was another case.

If the case of three years ago only involved the detection of the case, the case of five years ago was a living life.

Five years ago, he was also an incendiary criminal police officer from another province, and a plastic bag was also found at the scene of the crime.

Looking at the bulging bag, he grabbed it with his hand at random, and as a result, the gloves were pierced by the sharp object inside, and the bleeding caused severe exposure.

Later, it was found out that inside the black plastic bag were the discarded needles used by the deceased for intravenous injection.

The cause of the other party's death was also due to a large amount of drug abuse, and he was also a carrier of a highly infectious virus.

Unfortunately, the current investigation police were eventually infected with the virus because of that exposure.

It's ruined for a lifetime.

So, just now Janssen kicked it with his toes after he first found the black plastic bag, and

It's not touching with your hands.

The shoes worn by Yang Sen are explosion-proof shoes issued by the criminal police, and the quality is very good, and ordinary punctures cannot penetrate the shoes.

Carefully breaking off a branch, Janssen stabbed the black plastic bag.

Smack.

Objects in plastic bags fell into standing water.

Yang Sen looked at it, and his pupils dilated!

"Old white! Come on!"
