Since then, the provincial department has even organized a special training on the subject.

However, no matter how many similar cases there have been and how many times of training have been held, the crime scene after the heavy rain has always been a difficult point in the field investigation work.

It's just that the case three years ago made the current investigation more cautious when surveying the scene after the rain.

After all, there are still traces of the handkerchief back then.

According to the survey photos, there are obvious traces of soil erosion on the handkerchief.

There is also some dead grass sticking to it.

When it was found, half in its pocket, half outside.

If the handkerchief is in the pocket at the beginning, there is not much chance of mud washing and sticking to the dead grass.

But when handling a case, most people will have an expectation of being in a hurry to solve the case.

With such a big clue, it is difficult to express the encouragement of the exhilarating criminal police who handle the case in words and words.

After all, anything can happen after a rainstorm, whether it's dead grass or mud washing.

The four of them put on police uniforms and raincoats and set off quickly.

The Bailan River, the third largest river in Haizhou City, meanders through the city.

More than ten years ago, there were many light chemical factories along the Bailan River, and the whole Bailan River was stinking in those years, and the color of the river water was sometimes white, sometimes black, sometimes red, but it was not clear.

In recent years, Haizhou City's environmental remediation work has been very vigorous, including the Bailan River, and many light chemical plants along the rivers in Haizhou City have been shut down and relocated.

Since then, the water quality of the Bailan River has gradually improved, and it has become clearer and clearer.

In addition, domestic sewage is not directly discharged into the river, and the stinking Bailan River no longer has a strange color.

In recent years, many small amusement parks have been built around the Bailan River, and blue rubber hiking trails have been paved along the river, which has become a good place for citizens to take a walk and enjoy the cool air.

The place where the body was found was a small amusement park located within the jurisdiction of the Youyi Road Police Station.

The rain was pouring down, as if there was a flood in the Heavenly Palace, and the sluice gate had to be opened.

As soon as Lu Chuan and the others got out of the car, the raincoat was lifted by the strong wind, and the rain poured back and drenched through.

Because the wind was too strong, there was no way to open an umbrella, and the criminal policemen who got out of the car were all wet.

"Team Qin!"

The director of the Youyi Road Police Station approached Qin Yong and loudly introduced the situation.

"The body was found by a flood patrol officer, and it should have been swept ashore by the river."

The Bailan River, which is usually calm and waveless, is now undulating, and the water surface is already flush with the river embankment.

Even in the distance, the embankment has overflowed.

"Let's go, let's take a look!"

Wind and rain, naturally there were no onlookers, and the police at the police station did not pull up the cordon.

Lu Chuan and the four of them put on gloves, so there was no need to wear masks at this time.

The body lay flat on the blue rubber hiking trail of the riverbank, face down, with aquatic plants wrapped around its waist.

Liu Guodong stepped forward first and asked the director of the Youyi Road Police Station loudly, "Has anyone touched the body?"

The other party waved his hand: "When the patrolman saw it, he called the police directly and did not move."

It's good that I haven't touched it.

Liu Guodong nodded towards Lu Chuan and motioned to step forward.

Lao Bai and Yang Sen surrounded the periphery of the corpse, one clockwise and the other counterclockwise to investigate.

This is a routine survey rule, but in this situation at the scene, the heavy rain washed everything, and it is estimated that nothing will be found.

Lu Chuan walked around the side of the corpse, his face shocked.

Liu Guodong noticed the change in Lu Chuan's face: "What's wrong?"

"Master...... It's a carrion!"

Carrion?

Liu Guodong came around from the side when he heard this.

Because the corpse was lying flat on the ground, facing the side of the crowd was the back of the head, and the face was facing the river, so it had to go to the side

Stick your head out to see your face.

At this glance, I saw that half of the corpse's face was full of maggots crawling.

The raindrops the size of beans snapped on the corpse's face, and the maggots that were about to emerge were beaten back by the rain.

After a breath, he came out again.

Rotting corpses, heavy rain, Liu Guodong smiled bitterly.

After so many years as a police officer, Liu Guodong has encountered rotting corpse cases, not one or two.

Each one of them made him extremely impressed.

There is really no way not to be profound, and anyone who takes a look at the decomposed corpse will never forget it in this life.

"Let's get it back first, it's raining so hard that there's no way to conduct a survey."

Liu Guodong can be sure that this is not the first scene, so there is no need to worry about moving the body.

"Wang, come here."

The current survey is the first scene, followed by the forensic doctor.

Liu Guodong and their fellow investigators, they are not good at dealing with corpses, except for some physical surface investigations, others have to be forensic.

Wang Changjiang took Shen Yan and entered the scene.

"Take a look here."

Liu Guodong called Wang Changjiang to the side and glanced at half of the corpse's face.

"Rotting corpses?"

Wang Changjiang was slightly stunned, and then smiled bitterly.

Dissecting corpses, the last thing you want to encounter is a rotting corpse.

If nothing else, the taste is not something that ordinary people can resist.

The reason why it is not smelling now is because there is heavy rain cover, and the body has washed up from the river again.

But once it is sent to the dissection room, it is completely exposed.

"Xiao Shen, put on your gas mask."

As soon as Shen Yan heard it, she knew what she might have to face next.

What kind of corpse to encounter and what level of protective gear to wear are actually prescribed in forensics.

Gas masks are the highest level, and only when facing rotting corpses.

Of course, the general forensic doctor, or the forensic doctor who doesn't care too much, the experienced forensic doctor, can be solved with a mask.

In most cases, only female forensic doctors follow the protocol strictly, and when it is time to wear a gas mask, there is no ambiguity.

"Get the corpse in the car first, we'll do a routine survey of the surrounding area, go back and do a corpse examination first, and then you will dissect it."

Wang Changjiang nodded: "Okay, then let's go back first, and we'll do it when you're done."

When the medical examiner performs an autopsy, he will also do an autopsy.

However, the focus of the two inspections is different.

Forensic medicine focuses on determining the cause of death of the deceased, the time of death, and all examinations serve the ultimate purpose.

The autopsy is more focused on clues.

Whether it's the clues left by the murderer, or the clues left by the deceased themselves.

The point is who caused the death of the body.

Ordinary criminal police officers are not involved in the removal of corpses.

"Lao Bai, Lao Yan, take a hand!"

After calling the two of them, Lu Chuan had already moved the stretcher over.

「***！」

"Rotting corpses?"

Yang Sen and Lao Bai came over and accompanied Liu Guodong to straighten the corpse, and were startled when they saw the maggots on the corpse's face.

"It's okay, let's move."

Lao Bai nodded helplessly: "Fortunately, it rained heavily, otherwise I wouldn't have to eat today......
