National Forensic Doctor

Chapter 246 Low Temperature Burn

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

In terms of solving crimes alone, the number of cases Jiang Yuan has solved in recent times is indeed quite large.

Solving serious crimes one after another is an experience that ordinary criminal investigators dream of but is difficult to experience.

The third-class personal merit in the police system is relatively easy to obtain, but the difficulty of the second-class merit is quite high. Jiang Yuan has obtained two second-class merits in a row, which shows that what he has done is great. Something some police officers can’t do.

Forensic doctor Zhai didn't do it either.

He will serve in the provincial department not only because of his qualifications and academic qualifications, but also because of his relatively comprehensive technical mastery.

When he was transferred to the provincial department 30 years ago, Dr. Zhai was one of the few experienced forensic doctors in the province who graduated from a serious medical university.

On the other hand, in the era when Zhai's forensic capabilities were overwhelming, fingerprints were checked using fingerprint cards, let alone things like surveillance video or DNA technology, which was extremely inefficient.

Forensic identification was a technical force that could truly be called forensic science at that time. While forensic doctor Zhai cooperated with the criminal police to detect many cases, he also learned many skills on his own.

Unlike today's forensic doctors, many people focus on forensic clinical science. In Zhai's era, forensic anthropology was a daily routine, and forensic toxicology and even forensic entomology were all required to be involved.

Because there is nowhere to turn for help.

Nowadays, when forensic doctors encounter some technologies that they don’t understand well, they just turn to others for help.

This was Zhai's forensic era, and models were impossible or even unimaginable.

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

Back then, even senior technical personnel within the system could not get whatever information they wanted.

Despite this, Forensic Doctor Zhai is still extremely powerful.

In recent years, it is still a matter of taking action.

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

However, today's autopsy was extremely difficult, and his superiors deliberately asked him to wait for Jiang Yuan. Now that he saw someone, Forensic Doctor Zhai started to observe them carefully.

Jiang Yuan didn't expect it to be so spicy, so he operated step by step. There was nothing special about the autopsy process.

Forensic doctor Zhai was not surprised. After the body was delivered, he carefully examined it, but he could not come up with any valid conclusions.

It can only be said that an ordinary corpse with superb techniques is definitely not the work of a novice.

"Do you want to start cooking the corpse?" Jiang Yuan finished looking at the corpse and looked at forensic doctor Zhai.

"What are your thoughts?" Forensic Doctor Zhai was also worried about Jiang Yuan's youth and arrogance, so he put himself up.

Jiang Yuan shook his head and said: "I don't have any direct thoughts. The murderer's methods are very skillful."

"Well, this is not the first time a crime has been committed." Forensic Doctor Zhai immediately affirmed.

The idea was very close to him.

And people can't help but agree with the same views as themselves.

"Compared with the murderer in the reservoir case?" Forensic Niu was only assisting, but he still thought of Wang Guoshan immediately.

The two cases were not merged, but because of Liu Jinghui, everyone actually knew that the two cases were similar.

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

Forensic Doctor Zhai once again said "Yes" in agreement and said: "Those who kill people still have relatively few training opportunities. Those who kill a few people may not necessarily make much progress in their killing techniques compared to those who kill more than a dozen people." , it mainly depends on talent.”

Forensic Niu was stunned for a moment, then shook his head and said, "That's what you can say."

"In fact, there were a lot of murderers in the past, especially the gangsters before liberation, who later committed crimes." Forensic Doctor Zhai shook his head, not intending to talk any more, and said what he had said before, "Then let's start cooking. "

"I'll set up the pot for you. It's up to you to see if the bones are cooked later." Facing Forensic Doctor Zhai, Forensic Doctor Niu admitted his shortcomings without any shame.

His qualifications are much deeper than Jiang Yuan. Thinking back then, when he was still picking out green spots from rice in his jurisdiction, Jiang Yuan might not have had this function.

However, when compared with Dr. Zhai's qualifications, there is nothing to say.

Speaking of which, when Forensic Doctor Niu first joined the job, he also took a training class from Forensic Doctor Zhai.

The autopsy room here is regarded as the territory of Niu Forensic Doctor. He called the other two people and actively took out the pressure cooker and the steel pot. The former used electricity and the latter used gas. The two of them set up the stove and started a fire to boil water.

A normal person always weighs a hundred kilograms. Although the body dug out this time is extremely rotten and degenerated, the skeleton is there and the small pot will definitely not be able to cook it.

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

The capacity of the latter is not large enough, but you can cook one end and then the other, slowly and slowly, and you can always cook it to remove the bones.

The workload of cooking two people at one go is greater than cooking two or even four sheep.

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

Forensic doctor Zhai also actively helped.

That's what it's like to be a forensic doctor. No matter how high your rank is, you still have to do things as usual.

After busy completing the preparations and watching the two pots boiling, Forensic Doctor Zhai turned around and saw Jiang Yuan lifting the body bag to another autopsy table, looking like he was studying it seriously.

Forensic Doctor Zhai frowned, walked over and asked, "What did you find?"

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

"Has it been punctured?" Forensic Cow put down the clip and walked over to take a look.

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

"At that time, people packed the meat and put it in the refrigerator. That's how it was packed." Forensic Doctor Zhai explained with experience.

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

"Huh?" Forensic Doctor Zhai came over to take a look unexpectedly.

Sure enough, one corner of the red and blue plaid woven bag was discolored.

There are even red and blue markings on the outermost gray travel bag.

This certainly cannot be caused by pollution.

Forensic Doctor Zhai thought carefully and realized that this really looked like a mark caused by burning.

"Once the plastic bag is burned, it should be gone." Forensic Doctor Zhai muttered to himself.

"really."

Jiang Yuan also muttered.

Forensic Doctor Niu watched the two people thinking hard, and suddenly felt a little too lazy to think.

Apart from corpses, what he has done a little research on are paper towels, plastic bags or rubber, etc., which are still disgusting.

At this time, Jiang Yuan's mind suddenly flashed into the image of Da Zhuang hating riding in cars, and then the scene he went to the parking lot and scanned, and couldn't help but say: "It's a motorcycle."

"What?"

"Neither this travel bag nor the red and blue checkered bags can withstand high temperatures, that is, low-temperature burning. The exhaust pipe of a motorcycle!"

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

Although many locals in Zifeng Town have cars, most of them still ride motorcycles when going up the mountain.

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

Jiang Yuan used the anatomy table as a stool, turned the red and blue checkered bag sideways, and hung the heated end down, saying: "Look, if a motorcycle is transporting the body up the mountain, this end of the bag may touch the exhaust pipe. .”

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

"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 corpses, then adjusted the positions himself, and said a little uncertainly: "I don't understand motorcycles either, who does?"

The forensic doctors present shook their heads.

Forensic scientists study clothes or toilet paper. That's a job requirement. What's the point of riding a motorcycle?

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

"Do you want to do an experiment?" Forensic Doctor Zhai agreed.

When forensic doctors perform analyzes other than corpses, they often need to conduct experiments. For example, if it is speculated that the murderer packed the body into 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, forensic doctor Zhai thought about the origin of the motorcycle for a long time before he said: "It would be best to ask the local leaders to see if they can find a second-hand motorcycle dealer to coordinate and try out more vehicles."

Jiang Yuan was stunned for a moment, then agreed: "That's okay. That's fine."

Forensic Doctor Zhai felt strange: "How did you originally want to try?"

"Buy?" Jiang Yuandao: "A motorcycle shouldn't cost much."

Forensic Doctor Zhai was amused for a moment, and when he saw that Jiang Yuan was not smiling, he couldn't help but ask, "Is the county bureau's funds so sufficient now?"

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