Chapter 732

Zhan Kan assisted Jiang Yuan and carefully took the corpse out of the No. 1 grave.

The young forensic expert who came with him made a phone call and then whispered: "Team Jiang, Forensic Expert Zeng and the others will arrive soon; it's estimated it will take another half an hour."

"Good, after they arrive, start from No. 6." Jiang Yuan couldn't dig up six corpses alone. Even if his energy allowed it, it would be very difficult in terms of attention and time. Facing such a case, it's best not to let it go overnight. This is not only because it's not easy to defend the forest, but also because it's easy to rain in the morning and evening, and the danger of sudden temperature changes is a great enemy for open corpses.

Tao Lu held Huang Qiangmin with one hand and Qi Changye with the other, plus two semi-familiar faces, communicating in a low voice.

Jiang Yuan's attention was already focused on the corpse pit.

Jiang Yuan, Zhan Kan, and others continued the bone-picking work that the police officers hadn't finished before. At the same time, the police continued the task of collecting insects and soil that they had done before.

Bone by bone was put into the prepared box.

Zhan Kan took a section of bone, looked at it carefully, and whispered to Jiang Yuan: "The bones seem very clean. In this situation, is the time of death more than four or five years?"

On the bright white bones, there was not the slightest entanglement. The so-called entanglement refers to those tendons that are connected. In the later stage of corpse decay, tendons are the last body tissue to leave the bones.

Jiang Yuan had already looked at the bones just now. At this moment, he looked around and said: "You can be a little bolder."

"More than five years? Seven years?" Zhan Kan was surprised.

"More than eight years." Jiang Yuan said: "What do you think caused the decay rate of the corpse to slow down?"

For a corpse to decay to a completely clean degree, it really takes three to five years. Zhan Kan guessed four or five years, which was already guessing that the decay rate of the corpse at the scene was slow. But obviously, Jiang Yuan thought the decay rate of the corpse was far slower than Zhan Kan guessed.

Zhan Kan thought for a while: "I think the first is the cold climate, which will reduce the decay rate of the corpse. On the other hand, the environment in the forest will actually increase the decay degree... so I synthesized it."

"There is another reason, the wind is too strong." Jiang Yuan pursed his lips: "The wind in the capital is generally strong. Although the slope they chose has some ability to resist the wind, it is still not enough. Why does strong wind slow down the decay rate of the corpse?"

"Uh... because... the fly eggs were blown away?" Zhan Kan had almost forgotten all the books he read back then. At this moment, his brain felt like it was starting to grow again.

Jiang Yuan just nodded and said: "So, given the environment here, three or four years is likely not enough to form such clean bones; it must be at least 8 years."

"But there is water here, and the waterway is quite good, which should accelerate the formation of decay, right?"

"This is a hillside, water cannot stay, and insect eggs will be washed away instead." Jiang Yuan explained in a way that Zhan Kan could understand better.

Zhan Kan nodded repeatedly.

Several people continued to pick bones.

After picking almost enough, Jiang Yuan basically understood the situation in the grave, then got up and headed to the second grave.

Then it was the third and fourth graves, looking at them one by one.

Zeng Lianrong and the others were almost there, so Jiang Yuan had to look at the other corpses, and if he had any thoughts, it would be good to communicate in advance.

Although they were all on the same hillside, the distribution range was actually not small. There was always a distance of hundreds of meters from one grave to another. It was fast to fly with a drone, but it was a bit hard to walk with feet. The forest in the wild was not as easy as in a city park.

Almost when he walked to the sixth corpse burial site, Zeng Lianrong climbed up. He was old and carried a box himself, panting with exhaustion.

Seeing this, Jiang Yuan hurriedly let the old man rest first, then updated the news: "I just looked at the corpse at the No. 1 position. The time of death is about 8 years. The time of burying corpses in this area is longer than we expected."

"Brigade Qi and the others closed the case two or three years ago, right? That means the corpses have been buried for at least five years. Six corpses in five years is not much." Zeng Lianrong panted, but his brain was still clear, and he added: "Actually, there were many homicides in the early years, especially in the nineties, when it was just opened up. Ten billion people, nine billion were doing business, and one billion were looking for it. At that time, businessmen carried money with them when they went out..."

"That was really a golden age." Liu Jinghui also came over, listened to Zeng Lianrong's words, joined the chat, and sighed: "When I first started working, my master used robbery cases to train us. It's not like now, where encountering a violent crime makes people as nervous as anything."

"Indeed, I once dissected more than a dozen corpses in a week, and later I couldn't even move the corpses. However, it was different back then. Many family members were willing to help move the corpses. Once, I dissected in the victim's courtyard, and the neighbor's child was climbing the wall to watch..."

"Dissecting in the victim's home, can the victim's family stand it?" Zhan Kan worked in the clean and bright Beijing Dissection Center after graduation, with strict procedures and cumbersome formalities. He couldn't even imagine such a barbaric era.

Zeng Lianrong laughed, took a sip of water, stood up, and said: "Actually, it's only been twenty years."

"Actually, it hasn't been that long. We had this situation in Qinghe City a few years ago." Jiang Yuan also recalled and smiled: "Listening to my master, in relatively remote villages, the corpses were not necessarily moved back; they were dissected in a place found in the village."

Zhan Kan was surprised: "It wouldn't take a few hours to transport it back by car, right?"

"It might take a few hours to lift it onto the car." Jiang Yuan smiled and looked around: "It's impossible to have such good traffic as in Beijing."

"Indeed, as long as the corpse is on the car, it only takes a little time to drive here. Once here, it is sparsely populated. If there are two or three people to help, it is no problem to lift it for hundreds of meters. Instead, digging a pit is more tiring." Liu Jinghui was thinking on the way.

Jiang Yuan also nodded naturally: "This burial site is not suitable for single-person crimes."

This is the reason why he judged it to be organized crime.

If it were a lone serial killer, he would have to carry the corpse to the car alone, pay attention not to dirty the body, drive to this hillside, then carry the corpse up the mountain, climb hundreds of meters of difficult mountain roads, and then dig a deep pit that can bury people, and also have to shovel away other plants on it—anyone who is 35 years old and doesn't exercise all day wouldn't choose this plan.

But if three or four people work together, chatting and laughing, it is estimated that they can finish this work in an afternoon.

Two people are barely enough. Those who have carried drunks have experience. Carrying a corpse with two people is not much easier than carrying a corpse alone.

Liu Jinghui nodded and said: "So I have been thinking, how can a homicide case with several people cooperating, and with multiple victims, be silent? Not only did no one report it to make a contribution, but no one even reported the case."

"Isn't it because the situation of Brigade Qi is special?" Jiang Yuan had not had such an experience.

Liu Jinghui curled his lips: "How special can it be? It's even more impossible for spies to die quietly; it's just that there is no big investigation. Those peripheral members have a certain probability, but it's impossible for multiple people to be loners."

Jiang Yuan just nodded. He didn't think so much at all. Thinking must be after evidence. This is the way of thinking of forensic experts. As for Liu Jinghui's words, he was thinking from beginning to end.

"I'll go pick the corpses first." Zeng Lianrong had rested enough and took several forensic experts to get busy.

Jiang Yuan then came to the position of the No. 4 corpse to start digging.

No. 4 was a typical male corpse, and the time of death was also about six years.

No. 3 was a female corpse, and the time of death was also about six years. In fact, in Jiang Yuan's judgment, it was only two or three months apart from the time of death of No. 4.

Back to the No. 2 pit, the corpse dug out this time was male, and the time of death was about five years ago, but it was only a few months apart from the time of death of the No. 3 corpse.

"It seems that many things happened six years ago." Jiang Yuan could only draw a small amount of conclusions now and specially asked Zhan Kan to record them.

In the following time, Jiang Yuan also collected the dog's corpse in the No. 2 pit, and then went back to No. 5 and No. 6. The forensic experts brought by Zeng Lianrong had basically handled them clearly.

At this time, it was late, and everyone had no energy to socialize, so they took cars back to their homes.

Jiang Yuan followed back to the dissection center. At this time, the corpses of the non-mainstream religious case from the previous days had not been completely handled clearly.

"Zhan Kan, you find a corpse and do skull restoration." Jiang Yuan had not forgotten that he had this task.

Zhan Kan felt a bit guilty and asked: "Are you taking me to do it?"

"You do it yourself; I have other things to be busy with." Jiang Yuan said.

"Then you pick first; after you pick, I will pick."

"No need." Jiang Yuan said: "I'll take DNA from this dog first."
