Chapter 505: Deceased

Jiang Yuan carefully rubbed the fingerprint in the thread and took a photo.

For ordinary trace detection, fingerprints on round objects are already difficult to extract. It is equivalent to a process of turning a curved surface into a flat surface. One of Jiang Yuan's previous projects was the fingerprint on the center beam of a bicycle. Because the extraction level was too poor, it was difficult to identify.

The fingerprint in the thread is more difficult. Fortunately, the thread is very fine. Although it will cause the loss of key points, it will not turn the fingerprint into a 3D curved surface.

Jiang Yuan was very careful. He first took a photo, sprinkled powder, took a rubbing, and then took a photo. The process was complicated and time-consuming, but once it was extracted and entered into the system, it was an ordinary fingerprint and could be compared normally.

Jiang Yuan was not in a hurry to do other fingerprints. He waved to Mu Zhiyang, opened his notebook, and immediately logged into the background to compare this fingerprint.

"Guo Baozhi, male... deceased... well, died 3 years ago..." Jiang Yuan read it out with a little regret.

It was a good death, but it was a very uncooperative death.

Mu Zhiyang squatted beside him holding a laptop and saw it at a glance. He said, "That means the drug factory here has been open for at least three years? My goodness, how much money can it make?"

"The main reason why the drug factory cannot produce continuously is that the raw materials can't keep up." Jiang Yuan didn't know how to fight drug trafficking, and his knowledge of physical and chemical testing was just the knowledge he learned in school, but after last night's cramming, he had some understanding of the current situation of the domestic drug circle.

The so-called new drugs are actually synthetic drugs, that is, industrially produced compounds. Compared with the original opium heroin or cocaine, the increase in production of these things is self-evident. If there is no restriction, a set of reaction cycles, harvesting a few tons in a few days is low-end production capacity.

Nearly a hundred years ago, Germany could produce enough ice to be smoked by millions of people. If large chemical companies were to open up production capacity, it should not be difficult to use hundreds of tons as units.

In Jiang Yuan's opinion, the production line of methaqualone in front of him is probably facing the same problem.

Drug users are not staunch lovers of certain categories. They are not gourmets who must use drugs produced by a certain method from a certain place of origin. Drug users give all their love to drugs. They like whatever makes their brains perverted.

Therefore, this underground production line may be used to produce methaqualone now, and before or after, it can also produce other things.

In China, the production process of new drugs is difficult to control. China is the world's top manufacturing power. There may be more small factories in a township than in a country. They supply other industrial, chemical and pharmaceutical companies, and their content is usually the intermediate products of one or two compounds. If you are not a professional, you will be annoyed by the names, and it is difficult to determine the properties of its products, synthetic pathways or associated products and other related information.

From this perspective, foreigners like leaves so much, but it is not that they really like leaves, but it is just that they can get leaves more easily with the shrinking manufacturing industry. Especially after the technology of hydroponic leaves was developed, leaves became rampant.

Huang Li's drug trafficking gang placed the production equipment in the basement of the city, and the degree of secrecy was multiplied by 10. But Jiang Yuan guessed that its initial form must not be like this. It must have made a lot of money to have such an upgrade.

Even so, the engineer or worker responsible for the installation absolutely knew what he was doing... and the people around this person might also know something.

"Call Director Liu and report the situation." Jiang Yuan roughly flipped through Guo Baozhi's information. There was not much in the background, but if he visited, he should still be able to get something.

He believed that with Liu Jinghui's reasoning ability, he should be able to think of these without having to explain it himself.

Jiang Yuan looked at the complete set of methaqualone production equipment in front of him, many large tanks, many pipes, but the subsequent dryers, crushers, mixers, and tablet presses looked a little more technical...

In theory, you can buy very cheap chemical production equipment from the market to assemble a set of such a production line...

The real test is the source of the previous sequence and the subsequent waste including the treatment of production waste gas.

"Take photos first." Jiang Yuan knew that countless photos must have been taken during the previous investigation, but this thing was still the most important evidence and clue, so he had to do his job well.

Lu Tongda carried a camera on his back and took photos quickly. Criminal police still prefer to use cameras. Special equipment is easier to organize later. In addition, you can take more photos.

Jiang Yuan then looked for fingerprints on the surrounding tables. Most of them looked very similar to the fingerprints in his memory. He took the PAD and compared several places, proving that this was indeed the case.

Jiang Yuan then set his sights on the feed inlet and other places.

He directed Mu Zhiyang to remove a piece of the feed inlet and check it carefully. If nothing was found, he would find another one...

The reason for dismantling the feed inlet was that it was easier to dismantle here. It would be troublesome if a large device was dismantled and could not be put back. This kind of destructive inspection should also be put last.

Three feed inlets were dismantled in one breath, and three more fingerprints were found.

It seems that the installers were not very careful when doing their work, or that they no longer abide by the basic rules and regulations. They did not wear gloves when they should, and did not wipe and disinfect properly when they should. Of course, their consumers do not care.

"One is Guo Baozhi, and the other two are Li Chunqiu... 34 years old, also deceased." Jiang Yuan read the information on the computer, his face darkened.

Both of them worked for drug trafficking gangs and died at a young age. I think it is not related to death by illness.

"There is already a mature killing system." Jiang Yuan commented. This is the most worrying problem of criminal groups. The way they destroy social order will continue to deepen and expand.

The stable order and safe environment of today's society are built on such an unstable foundation.

The best way to maintain them is to catch them all in one fell swoop. Moreover, the death penalty is best.

Otherwise, there is actually a possibility of technology diffusion in detention places, and the degree of freedom in domestic prisons is quite high.

"Send a message to Director Liu." Jiang Yuan did not even think it was necessary to call.

Lu Tongda did as he was told, and Mu Zhiyang continued to carry the footprint light to help Jiang Yuan find clues.

For the next few hours, Jiang Yuan wandered around the production line.

He also knew that this production line was the focus of the first survey, but Jiang Yuan could not let it go.

This lasted until the afternoon. Jiang Yuan saw that the cooldown time in the system interface had ended, and decisively used the temporary +1 skill on the crime scene investigation.

The LV4 skill climbed to LV5 in one breath, and Jiang Yuan's eyes almost glowed.

His attention and concentration were greatly improved, as was his judgment, and Jiang Yuan began to have some ideas about the overall layout of the scene.

For example, the ventilation fan was installed at a low position, which was obviously to facilitate repair, replacement and control.

The production process of drugs has a smell, and the smell can be very strong.

Huang Li's drug trafficking gang should have considered many ways before finally choosing this method.

Jiang Yuan asked for a stool, climbed up by himself, looked carefully for half a minute, and then removed the ventilation fan.

After taking it and scanning it carefully, fingerprints also appeared inside.

Jiang Yuan collected them one by one, and this time, he found a new person.

"Finally found a living person for the time being." Jiang Yuan breathed a sigh of relief and continued to send clues to Liu Jinghui.

Mu Zhiyang looked at Jiang Yuan's gradually getting better and thought: Could this be the forensic doctor Jiang supported by Wu Jun?

Since the crime scene investigation was temporarily upgraded to LV5, Jiang Yuan has found four fingerprints and footprints in succession, and two traces of tools, which he also considered valuable.

Jiang Yuan's on-site investigation began to attract attention again at this time.

In terms of the professionalism and difficulty of crime scene investigation alone, it is still much weaker than the various skills of forensic doctors, especially skills such as anthropology.

Therefore, in places like the Changyang City Criminal Police Detachment, or institutions such as the Criminal Science Center, there are still many police officers with L crime scene investigation LV2 and above.

Even LV3 crime scene investigation technology should be mastered by someone.

Therefore, when Jiang Yuan used the LV4 crime scene investigation to scan the second time, the difficulty was still relatively high.

After upgrading to LV5, the results were completely different.

This is equivalent to the proportion of students who scored 60 points in an exam with simpler questions. The number of students who scored 70 points and 80 points also increased a lot, but when it came to 90 points, it was still very small. If it reached 95 points, the proportion would still be a sharp pyramid.

As Jiang Yuan sent messages to Liu Jinghui one by one, teams of criminal police were also dispatched.

Soon, various stories were spread in various WeChat groups:

[I heard that Jiang Yuan started killing again. ]

[He is so fierce that he can't eat without killing for three days. ]

[If I can catch all the drug trafficking gangs this time, I won't eat for three days. ]

[I heard that Jiang Yuan's master came to help, and then Jiang Yuan found something in a flash. ]

[I guess he is also a very powerful expert. 】

【Of course, the old experts in the past didn’t know as many new technologies as the young people today, and they may not have received systematic professional training, but some of the things they figured out were really amazing, and some of them seemed like superstition to us, but when the results came out, you had to admit it. 】
