Chapter 478: Deceased

Jiang Yuan carefully took an impression of the fingerprint in the thread and took a photo of it.

For ordinary trace evidence examiners, fingerprints on circular objects are already relatively difficult to extract. It is equivalent to a process of turning a curved surface into a flat surface. One of the accumulated cases Jiang Yuan once did was the fingerprint on the middle beam of a bicycle. Because the extraction level was too poor, it caused identification difficulties.

And the difficulty of fingerprints in threads is even higher. Fortunately, the threads are very fine, and although it will cause the loss of key points, it will not turn the fingerprint into a 3D curved surface.

Jiang Yuan did it carefully, first taking photos, then sprinkling powder, taking an impression, and then taking photos. The process was complicated and time-consuming, but once extracted and entered into the system, it was an ordinary fingerprint, and normal comparison operations could be performed.

Jiang Yuan wasn't in a hurry to do other fingerprints. He beckoned Mu Mu Zhiyang, opened the laptop, logged into the background immediately, and compared this fingerprint.

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

Died quite well, just died quite uncooperatively.

Mu Mu Zhiyang squatted beside him holding the laptop, glanced at it, and said: "That means this drug manufacturing factory has been open for at least three years? Good guy, how much money did this earn?"

"The main reason why drug manufacturing factories cannot produce continuously is that raw materials cannot keep up." Jiang Yuan didn't understand anti-drug, and his knowledge of physical and chemical testing was just what he learned in school, but after cramming last night, he already had some understanding of the current situation of the domestic drug circle.

So-called new drugs are actually synthetic drugs, which are compounds produced industrially. The increase in production of these things compared to the original opium, heroin, or cocaine goes without saying. If there are no restrictions, after a series of reaction cycles, harvesting several tons in a few days belongs to low-end production capacity.

The Nazi Germany of nearly a hundred years ago could produce enough ice for millions of people to smoke. If large chemical enterprises were to open up production capacity, it shouldn't be difficult to use tons as a unit.

And the methaqualone production line in front of Jiang Yuan, in his opinion, is probably facing the same problem.

The drug-using group is not a firm category lover. They are not gourmets. They don't have to use drugs produced by a certain method in a certain place. Drug users have given all their love to drugs. As long as they can make their brains abnormal, they like them all.

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

In China, the production link of new drugs is very difficult to control. China is a world-class manufacturing power. Perhaps a small factory in a town has more than a country. They supply other industrial, chemical, and pharmaceutical companies. Its content is usually one or two intermediate products of chemical compounds. If you are not a professional, you will be annoyed by the name, and it is also very difficult to determine the nature of its products, synthesis pathways, or by-products and other related information.

From this perspective, foreigners like leaves so much, actually, it's not that they really like leaves, it's just that they, whose manufacturing industry is shrinking, are easier to get leaves. Especially after the development of hydroponic leaf technology, leaves have become rampant.

The Huang Li drug trafficking gang put the production equipment in the basement of the city, and this degree of secrecy is multiplied by 10. But as far as Jiang Yuan guesses, its initial form definitely wasn't like this. It must have made a lot of money before it had such an upgrade measure.

Even so, the engineer or worker responsible for the installation definitely clearly knew what they were doing... and the people around this person might also know something.

"Call Liu Chu and report the situation." Jiang Yuan didn't even feel the need to make a phone call.

He believed that with Liu Liu Jinghui's reasoning ability, he wouldn't even need his own explanation to think of these.

Jiang Yuan looked at the complete set of methaqualone production equipment again, quite a few large tanks, quite a few pipes, but the subsequent dryers, crushers, mixers, and tablet presses looked a bit technical...

Theoretically, you can buy very cheap chemical production equipment from the market and piece together such a production line...

What is really tested is the source of the previous sequence, as well as the disposal of subsequent waste, including production waste gas.

"Take photos first." Jiang Yuan knew that the previous crime scene investigation personnel must have taken countless photos, but this thing was still the most important evidence and clue, and his own work had to be done well.

Jiang Yuan then searched for fingerprints on the surrounding tables. Looking at them, most of them were very similar to the fingerprints in his memory. He took the PAD over and compared several places, proving that it was indeed the case.

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

He directed Mu Mu Zhiyang to remove a feed inlet, then checked it carefully. If he didn't find it, he would look for another one...

The reason for dismantling the feed inlet is because it is easier to dismantle. Dismantling large devices and not being able to install them back is also a trouble. This kind of destructive inspection should also be placed last.

Dismantling three feed inlets in one breath, sure enough, three more fingerprints were found.

It seems that the installation personnel were not very careful when doing things, or they no longer followed the basic rules and regulations. They didn't wear gloves when they should, and didn't wipe and disinfect properly when they should. Of course, their consumers didn't care either.

"One is Guo Guo Baozhi's, and the other two are Li Chunqiu... 34 years old, also deceased." Jiang Yuan read a piece of information on the computer, his face sinking slightly.

These two were working for the drug trafficking gang, and both died young. Thinking about it, it had little to do with illness.

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

And 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 arrest them all. And it's best to have the death penalty.

Otherwise, detention places actually have the possibility of technical diffusion, and the degree of freedom in domestic prisons is quite high.

"Send a message to Liu Chu." Jiang Yuan didn't even feel the need to make a phone call.

Lu Lu Tongda did it hurriedly, and Mu Mu Zhiyang continued to carry the footprint lamp to help Jiang Yuan find clues.

For the next few hours, Jiang Yuan just turned around this production line.

He also knew that this production line was the focus of the first investigation personnel, but Jiang Yuan couldn't let go just because of this.

Persisting like this until the afternoon, Jiang Yuan looked at the cooling time in the system interface, and decisively used the temporary +1 skill on crime scene investigation.

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

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

For example, the ventilation fan, the installation position is low, obviously for the convenience of repair, replacement, and control.

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

The Huang Li drug trafficking gang should have considered many ways before choosing this way.

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

Shining with a light, there was actually a fingerprint appearing vaguely inside.

Jiang Yuan collected them one by one. This time, he made a fresh person.

"Finally found one who is still alive for the time being." Jiang Yuan sighed and sent the clue to Liu Liu Jinghui again.

Mu Mu Zhiyang looked at Jiang Yuan's gradually entering the state, and thought: Could this be the Forensic Doctor Jiang supported by Wu Jun?

After the crime scene investigation was temporarily upgraded to LV5, Jiang Yuan found four more fingerprints and footprints in succession, and two other tool traces were also considered valuable by him.

Jiang Yuan's crime scene investigation began to attract attention again.

Regarding the professionalism and difficulty of crime scene investigation alone, it is much weaker than various skills of forensic medicine, especially skills like anthropology.

Therefore, in places like the Changyang City Criminal Police Detachment, or institutions like the Criminal Science Center, there are quite a few police officers who have mastered crime scene investigation above LV2.

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

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

After upgrading to LV5, the result was completely different.

This is equivalent to an exam where the questions become simpler, the proportion of students who get 60 points has greatly increased, and the number of students who get 70 or 80 points has also increased, but to get 90 points, it is still very rare, and to get 95 points, the proportion is still a sharp pyramid.

As Jiang Yuan sent information to Liu Liu Jinghui one by one, teams of criminal policemen were dispatched.

Soon, various stories spread in various WeChat groups:

【I heard Jiang Yuan started killing again.】

【Rumor has it that Jiang Yuan has started killing again.】

【If this drug trafficking gang can be caught clean this time, I won't eat for three days.】

【I heard Jiang Yuan's master came to help, and then Jiang Yuan suddenly investigated something.】

【Presumably he is also a very awesome expert.】

【That's for sure. Although the old experts in the past didn't understand as many new technologies as the young people today, and might not have received systematic professional training, some of the things they figured out were really god-like, and some made us look like superstition, but the results came out, and you had to be convinced.】

I wanted to take a nap after updating last night, but I slept until this morning and didn't wake up. Finally, I slept for 13 hours, sleepy~ meow~ ===== CHAPTER 479 =====
