Chapter 234: Trash Sorting

Jiang Yuan automatically and consciously began to change into protective clothing, preparing to continue working.

Two corpses and one corpse were two concepts.

In the domestic environment, one corpse belonged to a normal homicide case. Taking Ningtai County as an example, if a corpse appeared, the first thing was the county bureau chief and the executive deputy chief in charge of criminal investigation appearing, the entire criminal police team dispatched, and reporting to the city bureau.

If the city bureau had resources, it would often give a certain amount of support, such as laboratory support, fingerprint support; if there were many forensic experts, it could also send a forensic expert over to help with the autopsy.

But if two corpses appeared, this case would directly rise to the level of the provincial department being informed.

If it went smoothly, that was fine; if it didn't go smoothly, the provincial department would soon dispatch a guidance group, or technical experts, to come and help.

Therefore, if a person accidentally killed another person, their technique of evading investigation might still play a role. But if they killed two people in one go, such as a young couple, a young husband and wife, etc., that case would directly receive the care of provincial-level experts.

By then, the fingerprints, footprints, bloodstains, and even image data at the scene would all likely receive the support of the provincial department's technical department.

To summarize, it was one sentence: killing one person, the investigation faced was worlds apart from two people.

And some killers, in a fit of rage, committed extermination cases, killing the victim's family of three; such killers faced the gaze of ministerial-level criminal investigation agencies and personnel.

Sometimes, fingerprints that couldn't be extracted at the grassroots level, when sent to the ministerial laboratory, could be easily extracted.

As for the special task force and police officers, facing cases of different levels, their attitudes were also completely different.

Not to mention anything else, if another corpse appeared now, Xu Taining wouldn't even need to consider going back; he would have to make something out of this case.

And judging from the current situation, the possibility of a third corpse appearing was extremely high.

The newly dug-out corpse bag was re-packed into a new corpse bag, and forensic expert Niu cushioned half his body in the basket, half-hugging the bag of corpse, and went up to the top of the mine tunnel.

The quality of the travel bag didn't feel particularly good either, plus it was unknown how long it had been buried under the water, so no one dared to pull the bag and lift it up.

And the bottom of the hanging basket wasn't a flat bottom; it was a steel grid with mesh eyes. The forensic experts were worried that the hanging basket would bump and damage the corpse as it stopped and started; even if it was already a dismembered corpse, at this time, the only clue everyone could look for was it.

When the hanging basket rose, several forensic experts swarmed up, hugged the corpse bag onto the flatbed cart, and then prepared to transport it directly to Qinghe City for autopsy.

As for forensic expert Niu, he was dirty all over, and only at the end was he pulled up.

Jiang Yuan was still hesitating whether to follow the corpse, but Wang Lan had already stopped him.

"Jiang Yuan, let's do the scene investigation first." Wang Lan said in front of the leaders: "Jiang Yuan's scene investigation is one of the best among forensic experts. Autopsy can be done by others first, and we can go see it later."

Forensic experts also needed to do scene investigation, especially in that kind of environment; the scene investigation done by forensic experts themselves and the scene investigation done by scene investigators were still not very different.

Jiang Yuan didn't have any opinions and nodded, saying: "I'll go up."

"Thank you for your hard work." Xu Taining rarely found time to say a word of comfort.

Ye Liang smiled and followed Wang Lan up to the bottom of the mine tunnel again.

After about 10 hours of work, the silt at the bottom of the mine tunnel had been cleared almost completely, and large concrete blocks had also been pulled up by equipment like hook machines.

That Komatsu micro-excavator, which was about the size of a donkey, was humming and digging trash downward at this time.

With dozens of meters of water pressing down above, the trash had become solid, and pieces were bonded into one body, which was also very laborious to dig.

Wang Lan saw Jiang Yuan come up, so she re-assigned him an area, and whispered: "Do you think the corpses here were done by Liu Jinghui?"

The killer of the reservoir corpse-disposal case, Liu Jinghui, had a confirmed number of murders exceeding 10, but he was very vague about the cases in the later period.

Regarding the case involving Zifeng Mountain, Ye Liangmei had been vague from beginning to end, which was also one of the reasons why Wang Guoshan thought it was necessary to continue the investigation.

Ye Liang was also very difficult to determine at this time, and could only say: "Regardless of whether it was done by Ye Liangmei, he is outside, and he must still have accomplices."

"Are you talking about the one who punctured the tires?" Wang Lan thought of it all of a sudden.

"Yes."

"The one who punctured the tires might only be an accomplice in one or two cases?" Wang Lan had encountered similar cases.

Serial killers and the serial killers described in Europe and America still had essential differences. Many killers killed due to some kind of interest relationship.

In that situation, the killer would have the possibility of temporarily finding accomplices. It was almost similar to the concept that an enemy's enemy is your friend.

But when the temporary union ended, some killers would continue to kill, while others would struggle for a lifetime to keep the secret.

By comparison, such cases were naturally easier to solve.

Jiang Yuan knew what Wang Lan meant, and also knew what answer she was looking forward to hearing.

But Jiang Yuan still shook his head and said: "It won't be a novice. I have carefully studied the case where Liu Chu had his tires punctured; the criminal acted very decisively, which could be called bold and careful. If it weren't for bad luck, Liu Chu might have died in a car accident at that time."

Pausing for a moment, Ye Liang added: "If the car accident caused a fire, or the location of the car accident was more in line with the killer's expectations, and he set another fire, the tire case might not even exist."

Wang Lan nodded slowly: "So, the other killer is still the main culprit?"

"Liu Jinghui is still locked up in prison; he can't independently or gather others to commit crimes again." Jiang Yuan said to this point, and added: "But if I were to do this case, I wouldn't link it to Ye Liangmei."

"Oh? Why?" Wang Lan was very surprised; merging cases was often the best way to solve a case.

"Liu Chu should have considered the issue of merging cases. He also didn't solve the case in a short time." Jiang Yuan's answer was also very reasonable.

Since coming to Zifeng Town, Jiang Yuan had consciously chosen a different perspective from Wang Guoshan.

In Jiang Yuan's impression, Wang Guoshan's reasoning ability was extremely strong.

A case he hadn't figured out after a month, if he followed his path again, even without considering the killer secretly destroying or being reminded and self-correcting, Wang Guoshan couldn't wait for another month.

If it was just to solve this case, then Jiang Yuan felt it could be completely waited for a few months later, and it wouldn't be too late to do this case.

And the most urgent thing at present was to find Wang Guoshan's whereabouts.

Seeing a person, or seeing a corpse, was always better than being missing.

Furthermore, Jiang Yuan's path was different from Wang Guoshan's; he just needed to follow the evidence.

Merging cases tested exactly the ability of reasoning and analysis.

That itself wasn't what Jiang Yuan was good at.

Wang Lan partially understood Ye Liang's train of thought, but didn't completely agree.

However, the person in charge of this case was Xu Taining, and it wasn't the turn of two forensic experts to direct the direction of the case.

The two ended the conversation and continued to create the mine tunnel.

More and more trash and construction waste were dug out.

By the time it was evening, another micro-excavator was sent down, and the speed slowed down slightly.

Then, another gray plastic bag was dug out.

"Wait a moment. Don't take it out." Jiang Yuan saw it from afar and walked over quickly.

When the previous corpse bag was dug out, everyone was still unsure if it contained a corpse, but this time, without saying, everyone could guess it.

Someone took photos, and Jiang Yuan looked at the corpse bag and the surrounding trash, analyzing calmly, saying: "Take photos of the trash too, and determine the location."

Wang Lan quickly realized and said busily: "Right, the trash should have been dumped in the same batch, which can also help analyze the source of the corpse."

We haven't seen the corpse yet, but from the news coming from the front, although the corpse provided a lot of information, it wasn't necessarily helpful for determining the source of the corpse.

In fact, for a corpse that had been dead for many years, identifying the source itself was very, very difficult. And the corpses whose sources could be identified accounted for a very large proportion of the total.

There was no data on the identification rate of criminal cases, but from another side, one could see the difficulty of identifying the source of a corpse--some famous mass graves in some areas, where extremely strong human anthropologists were dispatched to enter to identify the source of the corpse, facing a specific population in a known area, the identification rate was still not high.

For the forensic experts on the scene, any little thing that could improve the identification rate was helpful.

Jiang Yuan changed his gloves on the spot, added two more layers, and began to distinguish the trash on the spot.

Previously, doing the case of the scavenger old man had given him trash sorting (lv4), and at this time, applying it, the efficiency was also quite high.

The forensic experts beside him, although they also had a certain ability to identify evidence, seeing Jiang Yuan's actions, gradually waited in front of him. ===== CHAPTER 235 =====
