Since then, the provincial bureau even organized a special training session on the matter.
However, no matter how many similar cases there have been or how many training sessions, a crime scene after a heavy rain has always been a difficulty in crime scene investigation.
But the case from three years ago made investigators more cautious when examining post-rain scenes.
After all, the handkerchief from that year actually left traces to follow.
According to the crime scene photos, there were clear signs of soil wash on the handkerchief.
There were also some dried grass adhered to it.
When it was discovered, half was in the pocket and half was outside.
If the handkerchief was initially in the pocket, the likelihood of soil wash and adhering dried grass would not be high.
But when handling a case, most people have an eager expectation to solve it quickly.
Having such a significant clue encourages the investigating detectives in ways difficult to express in words.
After all, whether it's dried grass or soil wash, after a storm, anything is possible.
The four put on police uniforms, donned raincoats, and set off quickly.
The Bailan River is the third largest river in Haizhou City, winding and turning through the city.
A dozen years ago, there were many light chemical factories along the banks of the Bailan River. During those years, the whole river was filled with a stench, and the river's color was sometimes white, sometimes black, sometimes red, never clear.
In recent years, Haizhou City's environmental remediation efforts have been very strong. All the light chemical factories along many rivers, including the Bailan River in Haizhou City, have been shut down and relocated.
Since then, the water quality of the Bailan River has gradually improved, becoming clearer.
Moreover, domestic sewage is no longer directly discharged into the river, and the stinking Bailan River no longer has strange colors.
In recent years, many small parks have been built around the Bailan River, and blue rubber walking paths have been paved along the river, making it a good place for citizens to walk and relax.
The place where the body was discovered is a small park under the jurisdiction of the Friendship Road police station.
The rain poured down as if a flood had broken out in the heavens, opening the sluice gates out of necessity.
As soon as Lu Chuan and his team got out of the car, the raincoats were blown up by the gale, the rain pouring in, drenching them thoroughly.
With the wind so fierce, it was impossible to use an umbrella, so the detectives who got out of the car were all soaked.
"Captain Qin!"
The chief of the Friendship Road police station came close to Qin Yong, loudly explaining the situation.
"The body was discovered by a flood patrol team member; it should have been washed ashore by the river water at that time."
The normally calm Bailan River was now turbulent, the water level already flush with the embankment.
In some distant places, it had even overflowed the embankment.
"Let's go, have a look!"
With the storm raging, naturally, there were no onlookers, so the police from the station did not put up a cordon.
The four of them donned gloves, with no need to wear masks in such a situation.
The body lay flat on the blue rubber walking path on the embankment, facedown, with aquatic plants wrapped around the waist.
Liu Guodong was the first to approach, loudly asking the chief of the Friendship Road police station, "Has anyone touched the body?"
The other man shook his head, "The patrol reported it right after they saw it, didn't touch it."
Good, it hadn't been touched.
Liu Guodong nodded to Lu Chuan, signaling to proceed.
Old Bai and Yang Sen circled the perimeter of the body, one moving clockwise, the other counterclockwise for examination.
It's a routine investigation protocol, but with this rain-soaked scene, probably nothing significant would be found.
Lu Chuan circled to one side of the body, and his expression suddenly changed.
Liu Guodong noticed the change in Lu Chuan's face, "What's wrong?"
"Master... it's a decaying corpse!"
Decaying corpse?
At this, Liu Guodong came around from the side.
Since the corpse was lying flat on the ground, with the back of the head facing everyone and the face towards the river surface, one could only see the face by moving to the side and leaning over.
Upon seeing it, he saw half of the corpse's exposed face crawling with maggots.
Large raindrops pounded on the face of the corpse, driving the maggots that had just emerged back down with the rainwater.
But after a breath, they crawled out again.
A decaying corpse, a torrential rain, Liu Guodong smiled wryly.
In his many years of service, Liu Guodong had encountered more than a few cases involving decomposing bodies.
Each one left a particularly profound impression on him.
It's hard not to be so impressed; anyone who sees a decayed corpse once will never forget it for the rest of their life.
"Let's take it back first, no way to conduct an examination in such heavy rain."
Liu Guodong could confirm this wasn't the primary crime scene, so there was no concern about moving the body.
"Old Wang, come over."
The Crime Scene Investigation team advanced first, followed closely by the forensic doctor.
As crime scene investigation detectives, Liu Guodong and his team were not skilled in handling bodies; besides some external examination, the rest was up to the forensic doctor.
Wang Changjiang brought Shen Yan into the scene.
"Come take a look over here."
Liu Guodong called Wang Changjiang to the side, glancing at the half-exposed face of the body.
"A decaying corpse?"
Wang Changjiang was slightly dazed, then gave a bitter smile.
Encountering a decayed corpse is least desired when performing an autopsy.
Not to mention, the smell is not something an ordinary person could endure.
The reason it's not noticeable now is due to the heavy rain covering it, and the body was just washed up from the river.
But once taken to the autopsy room, it would be fully exposed.
"Shen, put on the gas mask."
Shen Yan knew immediately what they might face next.
In forensic terms, the type of corpse dictates the level of protective gear required.
A gas mask is for the highest level of protection, used when dealing with decaying corpses.
Nevertheless, ordinary forensic doctors, or those less meticulous, or experienced ones, would just use a mask to deal with it.
In most cases, only female forensic doctors strictly follow protocols, unequivocally wearing a gas mask when needed.
"Let's first get the body onto the vehicle. We'll conduct a routine crime scene investigation of the surroundings, then proceed with an external examination first, and you carry out the autopsy afterward."
Wang Changjiang nodded, "Alright, we'll head back first, and once you're done, we'll start the autopsy."
When performing an autopsy, forensic doctors also conduct an external examination of the body.
But the focus of their examinations differs.
Forensic doctors focus on determining the cause and time of death; all checks serve this ultimate purpose.
The crime scene investigation external examination focuses more on clues.
Whether they're traces left by the perpetrator or by the deceased themselves.
The focus is on who caused the death.
Generally, transporting the body is not a task for the detectives.
"Old Bai, Old Yan, lend a hand!"
When the two were called over, Lu Chuan had already brought over the stretcher.
"Damn!"
"A decaying corpse?"
Yang Sen and Old Bai came over, helping Liu Guodong adjust the corpse, and were startled by the sight of maggots squirming on its face.
"It's fine, let's move it."
Old Bai reluctantly nodded, "Thankfully, it's raining hard, or we wouldn't be eating today..."
