Chapter 505
Jiang Yuan carefully rubbed the fingerprints in the thread and took another photo.

For ordinary trace inspection, fingerprints on circular objects are already difficult to extract.It is equivalent to a process of turning a curved surface into a flat surface.One of the accumulated cases that Jiang Yuan had done was the fingerprints on the center rail of the bicycle. Because the extraction level was too poor, it was difficult to identify them.

As for the fingerprints in the thread, the difficulty has increased a lot. Fortunately, the thread is very thin. 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 took pictures, then sprinkled powder, took rubbings, and then took pictures.The process is complicated and time-consuming. However, once it is extracted and entered into the system, it becomes an ordinary fingerprint and can be compared normally.

Jiang Yuan was not in a hurry to do other fingerprints, so he beckoned for Mu Zhiyang, unfolded his notebook, and immediately logged into the background to compare the fingerprints.

"Guo Baozhi, male...deceased...well, he died 3 years ago..." Jiang Yuan read out with a bit of regret.

It's good to die, but it's not cooperative.

Mu Zhiyang was squatting next to him holding up his laptop, and he saw it with a glance, and said, "That means the drug factory here has been open for at least three years? Good guy, how much does it cost?"

"The main reason why the drug factory can't continue to produce energy is that the raw materials can't keep up." Jiang Yuan doesn't know drug control, and the physical and chemical testing is just the knowledge he learned in school. There is already some understanding of the status quo of the drug circle.

The so-called new drugs are actually synthetic drugs, that is, industrially produced compounds.Compared with the original opium, heroin or cocaine, it goes without saying that the output of these things has increased.If there is no limit, after a set of reaction cycles, harvesting several tons in a few days is a low-end production capacity.

Nearly a hundred years ago, Japan and Germany could produce enough ice for millions of people to smoke. If large chemical companies open up their production capacity, it should not be difficult to use hundreds of tons as a unit.

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

Drug addicts are not staunch category lovers, they are not gourmets, they must use drugs produced by a certain method in a certain place of origin, drug addicts give all their love to drugs, do whatever they want, as long as they can make their brains Perverted, they all like it.

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

In China, the production process of new drugs is difficult to control.China is the world's top manufacturing country. There may be more small factories in a town than in a country.They supply to other industrial, chemical and pharmaceutical companies, and their content is usually the intermediate product of one or two compounds. For non-professionals, it is annoying to hear the name, and it is difficult to determine the nature of its product, synthetic route or partner. Biological and other related information.

From this point of view, foreigners like leaves so much, it’s not that they really like leaves, it’s just that they are more likely to get leaves because of the shrinking manufacturing industry.Especially after the technology of hydroponic leaves was developed, the leaves became flooded.

Huang Li's drug gang put their production equipment in the basement of the urban area, and the level of secrecy was multiplied by 10.But as far as Jiang Yuanlai guessed, its initial form was definitely not like this, and it had to make a lot of money to have such an upgrade.

Even so, the engineer or worker in charge of the installation knows exactly what he is doing... and the people around this person may also know something.

"Call Liu Chu and report the situation." Jiang Yuan roughly flipped through Guo Baozhi's information, and there wasn't much in the background, but if he visited, he should be able to get something.

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

Jiang Yuan looked at the complete set of methadrane production equipment in front of him. There were many large jars and several pipelines. Instead, there were subsequent dryers, pulverizers, mixers, and tablet presses. They looked a little technical...

Theoretically, by purchasing cheap chemical production equipment from the market, one can create a production line like this...

What is really tested is the source of the pre-order, and the treatment of subsequent waste including production waste gas.

"Take pictures first." Jiang Yuan knew that countless photos must have been taken in the previous survey, but this thing is still the most important evidence and clue, and he has to do his job well.

Lu Tongda carried the camera on his back and hurriedly took pictures.Criminal police still prefer to use cameras. Specialized equipment is easier to tidy up afterwards. In addition, you can also take more films.

Jiang Yuan then searched for fingerprints on the surrounding tables. Looking around, most of them were very similar to the fingerprints in memory. He took the PAD and compared a few places to prove that it was indeed the case.

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

Commanded Mu Zhiyang to remove a piece of the feed inlet, and then checked it carefully, and found another one if he didn't find it...

The reason why the feed inlet is disassembled is because it is relatively easy to disassemble here, and it is also a trouble if the large device is disassembled and cannot be installed back.This kind of destructive inspection should also be placed at the end.

After dismantling the three feed ports in one go, three more fingerprints were found.

I think the installers are not very attentive when doing things, or they no longer abide by the basic rules and regulations. They don’t wear gloves when they should wear gloves, and they don’t wipe and disinfect properly when they should wipe and disinfect.Of course, their consumers don't care.

"One belongs to Guo Baozhi, and the other two belong to Li Chunqiu...34 years old, also deceased." Jiang Yuan read a message on the computer, his face darkened.

Both of these two worked for drug gangs, and both died at a young age. Thinking about it, the relationship with the death of illness is not too big.

"There is already a mature killing system." Jiang Yuan commented.This is the most worrying problem for criminal groups. The way they disrupt 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 go.And, preferably, the death penalty.

Otherwise, there is actually the possibility of technological proliferation in places of detention, 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 call.

Lu Tongda hurriedly followed suit, 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 surveyors, but it was impossible for Jiang Yuan to let it go because of this.

Persisting in this way until the afternoon, Jiang Yuan saw that the cooling time in the system interface was over, and decisively used the temporary +1 skill to investigate the crime scene.

The skills of LV4 climbed up to LV5 in one breath, and Jiang Yuan's eyes almost burst into light.

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

For example, the ventilation fan is installed at a low position, which is obviously for the convenience of repair, replacement and control.

The process of making medicines has a taste, and the taste can be very strong.

Huang Li's drug gang must have considered many methods before choosing this method in the end.

Jiang Yuan asked for a stool, climbed up by himself, looked at it for half a minute, and then took off the ventilation fan.

Take it over and scan it carefully, and there are fingerprints in it.

Jiang Yuan picked one of them one by one, but this time, he made a new one.

"Finally found one who is still alive for the time being." Jiang Yuan heaved a sigh of relief, and still sent clues to Liu Jinghui.

Mu Zhiyang looked at Jiang Yuan's getting better and better, and thought, "Could this be Jiang Forensic Doctor with Wu Jun's support?"
Since the crime scene investigation was temporarily upgraded to LV5, Jiang Yuan found four fingerprints and footprints in a row, and two tool traces, 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 medicine, especially skills such as anthropology.

Therefore, in places like the Criminal Police Detachment of Changyang City, or in institutions such as the Criminal Investigation Center, there are still quite a few police officers from Level 2 and above for crime scene investigation.

Even the 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 relatively high.

After upgrading to LV5, the result is completely different.

This is equivalent to the fact that the proportion of students who scored 60 points in the test with simpler questions has greatly increased. When it reaches 70 points, the number of students who score 80 points has also increased a lot, but when it reaches 90 points, it is still very small, and it takes 95 points. If so, the proportions are still sharply pyramidal.

Following Jiang Yuan's messages to Liu Jinghui, teams of criminal police were also dispatched.

Soon, various stories spread in various WeChat groups:
[I heard that Jiang Yuan started killing people again. 】

[The fierce flame is surging, the kind that doesn't kill people for three days and doesn't eat well. 】

[This time, if the drug gang can be caught, I won't eat for three days. 】

[I heard that Jiang Yuan's master came to help, and then Jiang Yuan immediately found something. 】

[Probably also a very powerful expert. 】

[That’s for sure. Although the old experts in the past are not as familiar with so many new technologies as today’s young people, and may not have received systematic professional training, some of the things they figured out are really amazing, and some of them are for us to see. It sounds like a superstition, but when the result comes out, you have to accept it. 】

　After the update last night, I wanted to take a nap, but I didn’t wake up until this morning, and finally slept for 13 hours, sleepy~meow~
