National Forensic Doctor

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

For ordinary fingerprint inspection, 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 the fingerprints Jiang Yuan once made was the fingerprints on the center beam of the bicycle. Because the extraction level was too poor, identification was difficult.

As for fingerprints in the thread, the difficulty increases 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 surface.

Jiang Yuan did it very carefully, first taking pictures, then spreading powder, taking rubbings, and then taking pictures again. The process is complicated and time-consuming, but 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. He called over Mu Zhiyang, unfolded his notebook, immediately logged into the backend, and compared this fingerprint.

"Guo Baozhi, male... deceased... well, died three years ago..." Jiang Yuan read out with a little pity.

The death was good, but the death was quite uncooperative.

Mu Zhiyang squatted next to him and held up his laptop. He saw it at a glance and said, "Does that mean the drug manufacturing factory here has been open for at least three years? Good guy, how much money does this make?"

"The main reason why the narcotics factory cannot produce continuously is that the raw materials cannot keep up." Jiang Yuan doesn't know much about anti-narcotics, and the physical and chemical testing is just the knowledge he learned in school. But after last night's hard work, he has no idea about domestic drug detection. We already have some understanding of the current situation of the poisonous circle.

The so-called new drugs are actually synthetic drugs, which are chemical compounds produced by industry. Needless to say, the production of these products has been increased compared to the original opium, heroin or cocaine. If there are no restrictions, after a set of reaction cycles, a few tons can be harvested in a few days, which is considered low-end production capacity.

Nearly a hundred years ago, Germany was able to produce enough ice to be smoked by millions of people. If large chemical companies opened 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 methaqualone in front of him is probably facing the same problem.

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

Therefore, this underground production line may be used to produce methaqualone now, and it may also be used to produce other gadgets 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 one township than in the entire country. They supply to other industrial, chemical and pharmaceutical companies, and their content is usually the intermediate products of one or two compounds. For non-professionals, it is very annoying to hear the names, and it is also difficult to determine the nature of its products, synthesis routes or companions. Biological and other related information.

From this point of view, the fact that foreigners like leaves so much is not actually because they really like leaves. It’s just that the shrinking manufacturing industry makes it easier for them to obtain leaves. Especially after the technology of hydroponic leaves was developed, leaves became abundant.

The Huang Li drug gang placed its production equipment in the basement of the city. This level of secrecy was multiplied by 10. But Jiang Yuanlai guessed that its initial form was definitely not like this. It had to make a lot of money to make such an upgrade.

Even so, the engineer or worker responsible for the installation definitely knows what he is doing...and the people around him may also know something.

"Call Liu Chu and report the situation." Jiang Yuan briefly looked through Guo Baozhi's information. There wasn't 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 things without having to explain himself.

Jiang Yuan looked at the complete set of mezzanine production equipment in front of him. There were many large tanks and many pipes. Instead, there were dryers, crushers, mixers, and tablet presses that followed. They looked a little bit technical...

Theoretically, by purchasing very cheap chemical production equipment from the market, you can build a production line like this...

The real test is the source of the upstream process and the subsequent treatment of waste including production waste gas.

"Take photos first." Jiang Yuan knew that countless photos must have been taken during the previous site survey, but this was still the most important evidence and clue, and he had to do a good job on his side.

Lu Tongda carried a camera on his back and quickly took pictures. Criminal police still prefer to use cameras. Special equipment is easier to clean up afterward. In addition, they can also take more films.

Jiang Yuan then searched for fingerprints on the surrounding tables. At a glance, most of them were very similar to the fingerprints in his memory. He took the PAD and compared several places, which proved that this was indeed the case.

Jiang Yuan then set his target at the feed port and other places.

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

The reason why the inlet is disassembled is because it is easier to disassemble. It is also troublesome to disassemble large devices and not put them back. This destructive inspection should also be placed at the end.

I dismantled three feed inlets at once, and sure enough I found three more fingerprints.

I think the installers were not very careful when doing their work, or in other words, they no longer followed basic rules and regulations. They did not wear gloves when they should wear gloves, and they did not wipe and disinfect properly when they needed to be wiped and disinfected. Of course, their consumers don't care either.

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

Both of them worked for drug gangs, and they both died at a young age. Thinking about it, it had little to do with their deaths from illness.

"There is already a mature killing system." Jiang Yuan commented. This is the most worrying issue 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 based on such an unstable foundation.

The best way to protect them is to catch them all in one go. And, preferably, the death penalty.

Otherwise, there is actually the possibility of technology 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 feel the need to call.

Lu Tongda quickly complied, while Mu Zhiyang continued to carry the footprint lantern to help Jiang Yuan look for clues.

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

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

This persisted until the afternoon. Jiang Yuan saw that the cooling time in the system interface was over and decisively used the temporary +1 skill for crime scene investigation.

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

His attention and concentration were greatly improved, as was 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, obviously to facilitate repair, replacement and control.

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

The Huang Li drug gang probably considered many methods before finally choosing this method.

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

He took it over and scanned it carefully, and fingerprints appeared inside.

Jiang Yuan picked them up one by one, and this time, he made a fresh person.

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

Mu Zhiyang looked at Jiang Yuan getting better and better, and thought to himself: Could this be Dr. Jiang who has Wu Jun's support?

Since the crime scene investigation was temporarily upgraded to LV5, Jiang Yuan found four more fingerprints and footprints in succession, as well as 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 skills of forensic medicine, especially skills such as anthropology.

Therefore, in places like the Changyang City Criminal Police Detachment, or in institutions such as the Criminal Investigation Center, there are still many police officers working at crime scene investigation level 2 and above.

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

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

After being promoted to LV5, the results are completely different.

This is equivalent to the fact that in an exam with simpler questions, the proportion of students who get 60 points has greatly increased. When it reaches 70 points, the number of students who get 80 points has also increased a lot. But when it reaches 90 points, it is still very few. It will take 95 points. Well, the proportions are still sharp pyramidal.

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

Soon, various stories spread in various WeChat groups:

[I heard that Jiang Yuan started killing people again. 】

[The fierce flames are raging. If you don’t kill anyone for three days, you won’t be able to eat well. 】

[If I can catch all this drug gang this time, I won’t eat for three days. 】

[I heard that Jiang Yuan’s master came over to help, and then Jiang Yuan immediately discovered something. 】

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

[That’s for sure. Although the old experts in the past did not know as many new technologies as the young people today, and they may not have received systematic professional training, some of the things they figured out were truly amazing, and some are for us to see. It sounds like superstition, but when the results come out, you have to accept it. 】
