Chapter 246 Low Temperature Burning

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

In terms of solving cases alone, Jiang Yuan has indeed solved a large number of cases recently.

Solving serious and major cases one after another is an experience that ordinary criminal investigators dream of, but it is difficult to experience.

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

Forensic doctor Zhai did not do it either.

He will work in the provincial department, not only because of his qualifications and education, but also because of 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 had graduated from a serious medical university and had experience.

On the other hand, in the era when Zhai's forensic medicine is full of fighting power, let alone surveillance video or DNA technology, fingerprints are checked with fingerprint cards, which is extremely inefficient.

Forensic medical appraisal was a technical strength that could be called forensic science at that time. While cooperating with the criminal police, forensic doctor Zhai solved many cases. On the other hand, he also taught himself a lot of skills.

Unlike today's forensic doctors, many people revolve around forensic clinical science. In Zhai's era, forensic anthropology was a part of daily life, and forensic toxicology and even forensic entomology were involved.

Because there is nowhere to turn for help.

Nowadays, when forensic doctors encounter some technologies that they don't understand, they just turn to other people for help.

This is the era of Zhai Forensic Medicine, a model that cannot be achieved or even imagined.

But on the other hand, Zhai's forensic skills are also very hard to learn.Unlike now, if you want to learn something, you can easily find learning resources.

Back then, even the senior technicians in the system could not get any information they wanted.

Despite this, Zhai Forensic Medicine's strength is still extremely strong.

In recent years, it is still a shot.

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

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

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

Forensic doctor Zhai was not surprised. After the corpse was delivered, he checked it carefully, but also couldn't come up with any valid conclusions.

It can only be said that ordinary corpses and superb techniques are definitely not done by novices.

"Do you want to start cooking the corpse?" Jiang Yuan looked at Zhai Forensic Doctor after reading the corpse.

"What do you think?" Forensic Zhai was also worried that Jiang Yuan was young and vigorous, so he set 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 to commit a crime." Forensic doctor Zhai immediately affirmed.

This idea is very close to him.

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

"Compared to the murderer in the reservoir case?" Forensic Niu was only on the sidelines as an assistant, but he immediately thought of Wang Guoshan.

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

Jiang Yuan said calmly: "It's definitely not alone. They are all skilled."

Zhai Forensic Doctor once again agreed with an "en" and said, "People who kill people still have relatively few opportunities to train. Those who kill a few people and those who kill more than a dozen people may not necessarily make much progress in their killing techniques. , mainly depends on talent."

Niu forensic doctor was taken aback, then shook his head and said, "You can say that."

"In the past, there were actually a lot of murderers, especially the gangsters before the liberation, and later they committed crimes." Forensic Zhai shook his head, not intending to continue the conversation, and said, "Then let's start cooking. "

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

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

However, compared with Zhai Fayi's qualifications, there is nothing to talk about.

Speaking of which, when Forensic Doctor Niu first joined the job, he also attended the training course of Forensic Doctor Zhai.

The dissecting room here is considered to be the territory of Niu forensic doctor. He called two other people and actively took out a pressure cooker and a steel pot. The former used electricity, while the latter used gas.

A normal person always weighs one hundred and ten catties. Although the corpse dug up this time is rotten and deteriorated, the skeleton is still there, and the small pot must not be able to cook it.

The electric pressure cooker is a commercial 16-liter one, which can barely cook the thigh bones of an ordinary person, but if the height is over 1.8 meters [-], like Jiang Yuan, you can only cook it in the steel pot next to it.

The volume of the latter is not large enough, but you can cook the other end after one end is cooked, and return slowly, and it can always be cooked to remove the bone.

Cooking two people at once is more work than cooking two or even four sheep.

Several forensic doctors got busy together, and it took a long time to straighten it out.

Forensic doctor Zhai also actively helped.

This is the case with forensic medicine, no matter how high the level is, they have to do things as usual.

Busily completing the preparations, watching the two pots boil, forensic doctor Zhai turned around again, and saw Jiang Yuan lifting the body bag to another autopsy table, looking serious.

Fayi 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?" Niu forensic doctor put down the clamp and walked over to look.

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

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

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

"Eh?" Fayi Zhai came over unexpectedly.

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

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

It certainly cannot be caused by pollution.

Forensic doctor Zhai thought carefully, and it really looked like a mark caused by burning.

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

"really."

Jiang Yuan also muttered.

Forensic doctor Niu watched the two of them contemplating, and suddenly felt too lazy to think about it.

Apart from the dead body, what he has studied a little bit is things like paper towels, plastic bags or rubber, which are still disgusting.

At this time, Jiang Yuan's mind suddenly flashed Da Zhuang's distaste for riding in a car, and then he went to the parking lot and scanned the scene. He couldn't help saying: "It's a motorcycle."

"what?"

"This travel bag and the red and blue grid bag cannot 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 there are many locals in Zifeng Town who have cars, most of the locals still ride motorcycles when they go up the mountain.

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

Jiang Yuan used the dissecting bed as a stool, turned the red and blue grid bag sideways, and let the heated end hang down, and said, "Look, if a motorcycle transports the corpse up the mountain, the end of the bag may touch the exhaust pipe. .”

"The temperature of the exhaust pipe is not very low." Forensic Zhai looked a little uncertain.

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

Forensic doctor Zhai looked at the two bags containing the corpses, and fiddled with the positions himself, and said a little uncertainly, "I don't know motorcycles either, who knows?"

The forensic doctors present shook their heads.

Forensic research on clothes or toilet paper is a job requirement, what about riding a motorcycle?
"Then find a few motorcycles and try it out." Jiang Yuan said.

"Do an experiment?" Forensic Zhai agreed.

When forensic doctors do this kind of analysis other than corpses, they often need to do experiments.For example, guessing that the murderer packed the body into a suitcase and transported it away, 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 saying, "It's best to ask the local leaders to see if they can find a second-hand motorcycle dealer, coordinate and try a few more cars."

Jiang Yuan was taken aback for a moment, and then agreed: "That's fine too. That's fine."

Forensic Zhai was surprised: "What did you want to try?"

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

Fayi Zhai laughed for a while, and seeing that Jiang Yuan didn't smile, he couldn't help saying, "Now the county bureau's funds are so sufficient?"

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