Jiang Yuan finished dissecting the body and cleaned up before putting it into the freezer. The three of them had almost finished eating the fatty chicken and pig stomach.

Everyone worked together to clean up the instruments and dissecting table. After soaking and scrubbing them with cleaning agents, they washed their hands and cleaned up the pots and pans they had used.

The autopsy room became clean and tidy, even cleaner than a five-star hotel if one were to sleep in it.

Finally, Jiang Yuan held the clay pot of fatty chicken and pig stomach and asked, "Where should I put this?"

"Put it in the cabinet. We can use it to collect stomach fluid and such in the future," said Forensic Ye casually, deciding to keep the clay pot.

Jiang Yuan ordered a large pot of fatty chicken and pig stomach, which could hold up to 10 kilograms of food. It was no problem for an average person's stomach capacity.

As a female forensic, Wang Lan was disgusted by the other forensic's disregard for vegetarianism. She waved her hand in front of her nose and said, "Stop fooling around. The words 'fatty chicken and pig stomach' are still written on the clay pot."

Forensic Ye laughed, "What's the big deal?"

Wang Lan rolled her eyes, "This is a famous restaurant in Longli County. The leaders who come to your county might go there to eat. Then, when they come back and see your autopsy, they'll find you bringing a bowl of stomach contents using the pot from that restaurant..."

Wang Lan didn't finish her sentence before everyone burst into laughter.

"It would be great if it could really happen," Forensic Ye said with a regretful expression.

Everyone imagined that scene and daydreamed.

If the leaders vomited, they could just clean it up. Speaking of which, which profession is the least afraid of dirtying the workplace? Forensics would probably say it's them, and no one would dare to disagree.

Wang Lan also laughed along, her expression relaxing a bit. "So, let's not put the clay pot in the autopsy room."

"Okay," Forensic Ye sighed. "I didn't think of that earlier."

"Exactly."

Forensic Ye nodded. "The autopsy room is a public place. It's not appropriate for me to put my privately bought clay pot there. I'll bring it over when the leaders are done with it."

This time, all four of them burst into laughter.

Behind the quiet green path of the funeral home, the laughter of the four people echoed, full of joy.

...

Back at the arranged guesthouse, Jiang Yuan bid farewell to his master Wu Jun and went back to his room to sleep.

The advantage of a poor and run-down guesthouse in a county was that it didn't exceed the standard, so each person could have their own room to sleep in, which was more friendly to old men who snored, farted, and smoked.

If they were on a business trip to a big city, the criminal police would have to share a room. The quality of life would greatly decrease.

Only at times like this would you realize that the small leaders who usually looked dignified and the young colleagues who looked like jade crowns also snored and ground their teeth when they slept, becoming uglier the more you looked at them.

Only at times like this could you fully understand the dissatisfaction of women.

Jiang Yuan didn't set an alarm clock. He rinsed his mouth with mouthwash and went to sleep.

A day and a night of on-site investigation was not just a matter of not sleeping. Concentrating and making judgments was actually very tiring.

Jiang Yuan could be willful because he was young. But at this point, once his emotions were released a little, he couldn't hold on anymore.

At the same time, Longde Village was in chaos.

Longli County organized a team of about 300 people and entered Longde Village to conduct DNA testing on all residents.

DNA testing with blood scabs was the fastest way to get results, but if the results didn't match, it would be a headache.

Hou Lejia was decisive in this matter. He reported to the higher-ups immediately and then mobilized the largest possible team to surround Longde Village, where the scavenging yard was located, for DNA testing.

A small number of people wouldn't work. In places like Longde Village, which was a combination of urban and rural areas, not only were there mixed crowds, but there were also a large number of young people and industrial workers.

Taking history as a lesson, these young people who had a certain degree of organization, were used to discipline, and had a highly consistent goal, and who had no house, no car, no savings, and no family, were easily incited.

As a police officer, Hou Lejia knew the power of deterrence the best.

The number of police officers in China was around one per thousand people, which meant that the proportion of police officers to the population was about 0.02%. This included one-third traffic police and one-third armed police.

With this configuration, they could only rely on deterrence.

More than 300 police officers, most of them concentrated together, did have an imposing presence.

Hou Lejia personally commanded and led the team, checking one by one, afraid of missing anyone.

No matter how many perpetrators there were, there was only one person who left behind DNA information. If they missed this person, all their work would be in vain.

This task sounded difficult, and it was even more difficult to carry out.

Fortunately, Hou Lejia had experience and borrowed some police officers from the local police station. They were divided into regions and started the DNA testing one by one.

By the time Jiang Yuan woke up, it was already noon the next day.

In Longde Village, the local DNA testing was already halfway done.

Jiang Yuan quickly entered the crime scene. At the entrance, he heard the captain of the criminal police, Hou Lejia, making a phone call:

"It can be done in two days."

"If it can't be done, I'll come and see you."

"Old leader, the police in Beijing handle cases like this with over a thousand people. It's common for them to have two or three thousand people. How can we compare to them?"

"Yes, I'll try to save on the budget for the case."

After hanging up the phone, Hou Lejia complained to the people next to him, "They don't give us enough people, they say there's no money, but they keep urging us for results. Where am I supposed to find the results for them?"

Jiang Yuan quickly walked into the courtyard, with the image of the captain of the criminal police still vivid in his mind.

It was clear that he hadn't slept or eaten properly since being woken up. I guess Hou Lejia knew it would be like this, so he took advantage of the time when there was no major action to take a nap.

For the criminal police, it was common to go without sleep for 72 hours when dealing with a case where the suspect was unknown. Although the captain of the criminal police had the title of captain and seemed like a leader, he was still a criminal police officer.

Jiang Yuan looked at Hou Lejia and couldn't help but admire him. Organizing a large-scale operation sounded impressive, but it was difficult to execute.

If it were a cultural event, one could use eloquent words to describe it, and it would be considered successful as long as it ended in victory.

However, police operations were different. They had specific targets from the beginning. If the targets were not achieved, how could they be considered successful?

The courtyard of the scavenger.

The number of items didn't seem to have decreased much, but in terms of quantity, there might have been hundreds less.

Jiang Yuan didn't waste time talking. He changed his clothes, put on a mask and gloves, and quietly joined the others.

The day passed quickly.

The pressure on Hou Lejia was increasing, and his eyes were visibly red.

Fortunately, the DNA sampling was finally completed. The large team finally withdrew without causing any accidents, which made him feel a bit relieved.

But the relief only lasted a few hours.

In the evening, Hou Lejia found Jiang Yuan and said, "The DNA didn't match."

We are "pawread.co𝑚", find us on google.

Wu Jun seemed to have anticipated this. He had been waiting in the courtyard and stepped forward to say, "The DNA didn't match, possibly because the target is not in the samples."

He put it delicately, but what he meant was that the murderer was not among the sampled population.

If there was no oversight, it meant that the murderer did not live in Longde Village.

This wasn't surprising. People's range of activities was large, and when Longli County defined the scope, it was obviously too late.

However, for Hou Lejia, the psychological pressure was immense.

"Ah, we need to adjust our investigation direction now," Hou Lejia said, looking at Jiang Yuan and Wu Jun.

The forensic team of Longli County couldn't come up with any good ideas. Forensic Ye Xiaogroup seemed like a fool, only knowing how to say "oh oh oh". The crime scene investigators found nothing, and the trace examiners were all pretending to be dead.

Hou Lejia was looking at Jiang Yuan, hoping he could provide some new clues.

If not, this case would be in jeopardy.

In Jiang Yuan's mind, he recalled the appearance of the bloodstain analysis. Although he didn't have any ideas, it made him more certain that the bloodstain he found that day was very likely the murderer's.

"I see that there are surveillance cameras on the road to Longde Village," Jiang Yuan asked, "Can we check all the vehicles and people who entered and exited Longde Village that day?"

If they weren't in the village, they must have entered or exited the village.

Hou Lejia hesitated slightly and said, "We have discussed this. Longde Village is a border village. Many people come and go by bus or taxi..."

"The murderer might have his own transportation," Jiang Yuan refuted Hou Lejia's words, "And it's likely a private car."

"Why?"

"Because the murder weapon wasn't found. If he's not from Longde Village, he either discarded it, took it away, or burned it."

Hou Lejia suddenly realized, "That's true. The murder weapon would be covered in blood, and the smell would be strong. If he took a taxi, it would be noticed. I'll assign two people to follow this lead."

He was referring to public transportation like buses and taxis. If there was a smell of blood, someone would have noticed. Sending two people to ask around on the route wouldn't take much effort and would cover most of the bases.

As for the remaining manpower, it would naturally be invested in the conspicuous process of searching for cars to do DNA testing.

"Thank you, Forensic Jiang. You've worked hard." Hou Lejia thanked Jiang Yuan and hurriedly left with his phone.

Jiang Yuan just smiled. He knew very well that Hou Lejia was more worried about the car search.

Because the search was based on the blood drop he found. If the blood drop was wrong, and they continued to invest a large amount of resources, it would become a joke.

So, when he asked Jiang Yuan, he was also testing whether Jiang Yuan was confident.

Jiang Yuan confidently gave him an answer.

For such a thing, Jiang Yuan himself was not afraid.

Half of Longli County was turned upside down because of this.

At this time, a private car driver, during the DNA test, provided an important clue.

That day, when he picked up his car from a parking lot not far from the crime scene, he smelled a strong smell of blood nearby.
