Chapter 245 Low Temperature Burning

Chapter 246 Low-temperature burn

When Forensic Doctor Zhai came to Qinghe City, he kept hearing Jiang Yuan's name.

In terms of solving cases alone, Jiang Yuan has solved a lot of cases in recent times.

Solving major cases in succession is an experience that ordinary criminal investigators dream of, but it is difficult to experience.

The third-class merit of the police system is relatively easy to get, but the difficulty of the second-class merit is quite high. Jiang Yuan has won two second-class merits, which shows that what he did is something that most police officers cannot do.

Forensic Doctor Zhai did not do it either.

He will serve in the provincial department because of his qualifications and academic qualifications, as well as his comprehensive technical mastery.

When he was transferred to the provincial department 30 years ago, Forensic Doctor Zhai was one of the few professional forensic doctors in the province who graduated from a regular medical university and had experience.

On the other hand, in the era when Forensic Doctor Zhai was extremely powerful, let alone surveillance videos or DNA technology, fingerprints were checked with fingerprint cards, which was extremely inefficient.

Forensic identification was the technical force of forensic science at that time. While cooperating with criminal police, forensic doctor Zhai solved many cases, and on the other hand, he also learned a lot of skills by himself.

Unlike today's forensic doctors, many people are focusing on forensic clinical medicine. In the era of forensic doctor Zhai, forensic anthropology was part of daily life, and forensic toxicology and even forensic entomology were all required.

Because there was nowhere to ask for help.

When forensic doctors today encounter some technologies that they don't understand, they directly ask for help from others.

This was the era of forensic doctor Zhai, a model that could not be done or even thought of.

But on the other hand, forensic doctor Zhai's technical learning was also very hard. It's not like now that you can easily find learning resources if you want to learn something.

In those days, even senior technicians in the system could not get any information they wanted.

Despite this, forensic doctor Zhai's strength is still very strong.

In recent years, he still gets what he wants.

Thirty years of high-level experience can be said to be a dimensionality reduction strike for the murderers who are mainly novices.

However, today's autopsy was extremely difficult, and the higher-ups wanted him to wait for Jiang Yuan. Now that he saw him, Forensic Doctor Zhai began to observe him.

Jiang Yuan didn't expect so much, so he followed the procedure step by step. The autopsy process did not show anything special.

Forensic Doctor Zhai was not surprised. After the body was delivered, he carefully checked it once, and he also couldn't come up with any effective conclusion.

It can only be said that the ordinary body and superb technique are definitely not the work of a novice.

"Do you want to start cooking the body?" Jiang Yuan looked at the body and looked at Forensic Doctor Zhai.

"What do you think?" Forensic Doctor Zhai was also worried that Jiang Yuan was young and energetic and would put himself on the line.

Jiang Yuan shook his head and said, "I don't have a direct idea. As for the murderer, his technique is very sophisticated."

"Well, it's not the first time he committed a crime." Forensic Doctor Zhai immediately affirmed.

This idea is very close to his.

And people always can't help but agree with the same point of view as themselves.

"Compared with the murderer in the reservoir case?" Forensic Doctor Niu was only assisting at the side, but he still thought of Wang Guoshan at the first time.

The two cases were not combined, but because of Liu Jinghui, everyone actually knew that the two cases had something in common.

Jiang Yuan said calmly: "It's definitely not the same person. They are all very skilled."

Forensic Doctor Zhai agreed again and said, "People who kill people have relatively few opportunities to train. Those who kill a few people and those who kill more than ten people may not be able to make much progress in their killing methods. It mainly depends on talent."

Forensic Doctor Niu was stunned, then shook his head and said, "Only you can say this."

"In fact, there were many murderers in the past, especially the violent bandits before liberation, who committed crimes later." Forensic Doctor Zhai shook his head and didn't want to talk more. He brought up the previous words and said, "Then start cooking."

"I'll set up the pot for you. When the bones are cooked, you will have to watch it." Facing Forensic Doctor Zhai, Forensic Doctor Niu admitted his shortcomings without any shyness.

His qualifications are much deeper than Jiang Yuan. Back then, when he was still picking rice and green spots in the jurisdiction, Jiang Yuan might not have this ability.

However, there is nothing to say about his qualifications compared to that of Forensic Doctor Zhai.

In fact, when Forensic Doctor Niu first joined the company, he also took Forensic Doctor Zhai's training course.

The autopsy room here is considered to be Forensic Doctor Niu's territory. He called the other two people and actively took out the pressure cooker and steel pot. The former is electric and the latter is gas. The two of them put up the stove and started a fire to boil water.

A normal person always weighs more than 100 kilograms. Although the corpse dug out this time is rotten and deteriorated, the skeleton is there, and the small pot is definitely not enough to cook it.

The electric pressure cooker used is a commercial 16-liter one, which can barely cook the thigh bone of an ordinary person, but if the height is over 1.85 meters, like Jiang Yuan, you can only use the steel pot next to it to cook it.

The volume of the latter is not large enough, but you can cook one end after finishing the other end. Although it is slow, it can always be cooked to remove the bones.

Cooking two people at a time is a greater workload than cooking two or even four sheep.

Several forensic doctors worked together and it took a long time to sort out the situation.

Forensic doctor Zhai also actively helped.

Being a forensic doctor is like this. No matter how high your rank is, you have to do your job as usual.

Busy to complete the preparations, watching the two pots boiling, forensic doctor Zhai turned around and saw Jiang Yuan put the body bag on another dissection table, looking like he was studying it seriously.

Forensic doctor Zhai frowned and walked over to ask: "What did you find?"

"These body bags seem to have changed color." Jiang Yuan was looking through the outermost travel bag.

"Is it punctured?" Forensic doctor Niu put down the clamp and walked over to see.

"There are some puncture marks on the outer layer, but it's not mainly here." Jiang Yuan turned up the inside of the two layers of body bags and said: "You see, in order to move the body, the murderer first dismembered the body, cut it into plastic bags, then put the plastic bags into red and blue checkered bags, and finally put the red and blue checkered bags into gray travel bags."

"At that time, people put meat in refrigerators, that's how it was packed." Forensic doctor Zhai explained with experience.

Jiang Yuan nodded and said, "But the discoloration of this bag is more likely caused by burning."

"Huh?" Forensic Doctor Zhai came to see unexpectedly.

Sure enough, one corner of the red and blue checkered woven bag did change color.

Even in the outermost gray travel bag, there were red and blue marks.

This definitely cannot be caused by pollution.

Forensic Doctor Zhai thought carefully, this really looks a bit like a trace caused by burning.

"The plastic bag should be gone once it is burned." Forensic Doctor Zhai muttered to himself.

"Indeed."

Jiang Yuan also muttered.

Forensic Doctor Niu watched the two people pondering and suddenly felt a little lazy to think.

Apart from corpses, he had done a little research on things like paper towels, and plastic bags or rubber were still disgusting.

At this moment, Jiang Yuan suddenly thought of Da Zhuang's dislike of riding in a car, and then he went to the parking lot and saw the scene. He couldn't help but say, "It's a motorcycle."

"What?"

"This travel bag and the red and blue checkered bag can't withstand high temperatures, that is, low-temperature burning. The exhaust pipe of the motorcycle!"

There is a big reason why Jiang Yuan said this, that is, there are some traces of motorcycles in the parking lot near the mine, but few traces of cars.

Although many locals in Zifeng Town have cars, the locals still ride motorcycles to go up the mountain.

Motorcycles are also a more popular means of transportation than private cars.

Jiang Yuan used the dissection bed as a stool, turned the red and blue checkered bag horizontally, and let the heated end hang down, saying, "Look, if the body was carried up the mountain by a motorcycle, this end of the bag might touch the exhaust pipe."

"The temperature of the exhaust pipe won't be very low." Forensic Doctor Zhai looked a little uncertain.

"Hmm... some kind of motorcycle with a relatively low exhaust pipe temperature?" Jiang Yuan was not too familiar with this aspect.

Forensic doctor Zhai looked at the two bags containing the bodies, and fiddled with their positions. He said uncertainly, "I don't know anything about motorcycles either. Does anyone know?"

The forensic doctors present shook their heads.

Forensic doctors study clothes or toilet paper, which is a job requirement. Riding a motorcycle is nothing?

"Then let's find a few motorcycles to try." Jiang Yuan said.

"Do an experiment?" Forensic doctor Zhai agreed.

When forensic doctors do this kind of analysis other than corpses, they often need to do experiments. For example, if it is speculated that the murderer put the body in a suitcase and transported it away, then it is necessary to find a colleague who is slightly taller and heavier to sleep in the suitcase.

However, the source of the motorcycle made Forensic Doctor Zhai think for a long time before he said: "It's best to ask the local leaders to see if we can find a second-hand motorcycle dealer to coordinate and try a few more vehicles."

Jiang Yuan was stunned when he heard it, and then agreed: "That's fine. That's good."

Forensic Doctor Zhai was surprised: "How did you want to try it?"

"Buy?" Jiang Yuan said: "The motorcycle shouldn't cost much."

Forensic Doctor Zhai laughed for a while, and then saw that Jiang Yuan didn't laugh, and couldn't help but say: "Is the county bureau's funding so sufficient now?"

"Let the bureau buy it?" Jiang Yuan couldn't help but nodded: "That's fine. That's good."
