National Forensic Doctor

The first people to be caught were Zhang Jing's family, who were traveling as a family of four.

As a clerk, he heard from a certain channel that he could buy counterfeit 20-yuan notes at a 20% discount that looked like real ones, and he never forgot about it. When his boss went bankrupt, he took his wife, mother, and mother-in-law with him on a trip.

Zhang Jing himself owns a small mobility car, which cannot be sold for much money, but it can be used for self-driving trips without any problem. In fact, for so many years, he and his wife have always planned to travel and tried to do the things they did in various short videos, but they always failed to make the trip.

The main obstacle is of course money. Zhang Jing's monthly income is only three to four thousand yuan, and his wife always stops working after a period of time. It is common to fire the boss, but it is rare to bring money home.

The collision between the tight economic situation and the dream was easily solved after getting the counterfeit currency.

Zhang Jing doesn’t think there’s anything wrong with using counterfeit money. He had received counterfeit money before, so he couldn't actually hand it over to the bank. He always found some nooks and crannies to spend it.

This time I got a large amount of counterfeit money. According to Zhang Jing's thinking, he could use the same approach to deal with it. However, the face value of 20 yuan was relatively low, and he had to drive all the way, so Zhang Jing simply went to town on his mother and mother-in-law.

The two old ladies are usually good at the vegetable market. They never suffer losses and have some experience in using counterfeit money. They have no psychological barriers to using counterfeit money. On the contrary, they feel that it is very good to travel for free and eat and drink at discounts.

Similarly, Zhang Jing's wife did not express any objection. Generally speaking, this is a family with very little legal knowledge.

It may sound a bit unbelievable to many people, but in the huge China, there are so many similar families, including those who spend money to buy their children and wives from traffickers. There may be some respect for the law, but definitely not many.

In just two days, Liu Jinghui found 12 families like Zhang Jing and arrested them all.

It took the entire Ningtai County Bureau to escort everyone back, and Liu Jinghui's coordination was indispensable during this process.

There are a total of 33 suspects, none of whom are career criminals, and none of them even has a criminal record.

Of course, if any of them had received corrections from prison college, they would definitely not commit such a stupid crime.

However, arresting these peripheral gangsters is not the goal of Jiang Yuan's special case team.

After Liu Jinghui actively participated in the interrogation for a day, he began to list more targets on the whiteboard:

"All the counterfeit banknotes were obtained through express packages. The package was delivered to Chiyong City... We can check these express packages, but Chiyong is also very big..."

"These people are mainly connected through social media, especially software for making friends with strangers. In this regard... I will contact the Internet Security Brigade_"

"The money...the money paid by these people has probably been washed away, but it still needs to be traced..."

When Liu Jinghui finished summarizing some key points, his frown became even heavier.

Except for the first one, which was to follow the express delivery and then check the surveillance, maybe he could get something, the other two crimes were committed through the Internet, and his reasoning skills had almost no effect.

This is why the number of telecom fraud cases has increased rapidly, accounting for more than half of all cases.

When the police use high-tech means, criminals in real society feel very uncomfortable, but when criminals also use high-tech means, the police also feel uncomfortable.

The two sides seemed to be trying to kill each other across a layer of net made by programmers, so the fangs and claws were no longer needed.

"I'll go to Chiyong City." Wang Chuanxing felt that this thread was still within his control.

Originally, it was to chase the courier's order number, then find the courier and ask the order taker, and then find the appropriate surveillance to find the suspect. It is basically the simplest criminal police method, applicable to all ages and all ages. Police participants with IQ levels, including agencies and leaders.

And this kind of injury mode without any sense of beauty is exactly what Liu

Jinghui is not really the original spring. However, this case is all about this kind of head-on approach.

"Chiyong is quite far away. Of course you are willing to go on a business trip." Liu Jinghui also wants to solve cases, but at his age, he has solved so many cases, and just solving one case after another is really not exciting at all. .

Work also needs some beauty and relaxation. Unfortunately, this case is a rare one. Liu Jinglian sat down and shook his head.

Wang Chuanxing is still young and cannot understand Liu Jinghui's pursuit, but he can still bear to solve the case in such an ugly way...

"Take a few more people to the Chiyong Bar. When you get there, check out the local printing shops and companies that do advertising. In short, this counterfeiter first created the software, and secondly, he should have a certain amount of knowledge. Operational experience." Jiang Yuan has also been busy with this case these two days. Although there is no decisive conclusion, the information given at this time has suddenly narrowed the scope.

Gu Zhanhui couldn't help but ask: "What did you see?"

Jiang Yuandao; "From the analysis of counterfeit currency, this counterfeiter still uses the printing method. The printer is an Epson R330 printer. It has a hot stamping machine and a paper cutting machine. It requires a certain space, professional technology, and It’s professional paper and ink…”

He has the skill of Document Inspection LV3. He didn’t have much chance to use it before, but now it’s very easy to take it over and see how it is produced.

Liu Jinghui was doing fewer economic investigation cases. He scratched his head and said, "Can't the printer print banknotes?"

"There is such a threshold in the program, and several Epson series have been cracked."

"Cracked?"

"Well, including the electronic version of 20 yuan, they are everywhere on the dark web. If you buy a counterfeit currency template, it comes with a complete set of counterfeiting procedures. If you don't need a few banknotes, there are not many people who dare to follow it."

Liu Jinghui was surprised: "The counterfeit currency template you mentioned is like the reason why the protagonist in the old police movies was often hunted all over the world..."

"That's pretty much it."

"The black market really has everything." Liu Jinghui didn't have much emotion. Domestic regulations are already very strict. If you go abroad, not to mention the sale of people, arms and drugs on the dark web, just counterfeit currency. One piece, they sell it directly, and there must be semi-finished products and raw materials.

Liu Jinghui quickly accepted the setting given by Jiang Yuan, and the reasoning followed: "The counterfeiter has certain technical ability, but it should not be very strong. He should be relatively young and impulsive. In addition, he must have a separate room. and factory buildings displaying machines, raw materials, and especially counterfeit coins for finished products..."

Liu Jinghui made a brief analysis and continued: "The printing shop mentioned by Jiang Yuan should really be considered. In addition, following the Epson printer mentioned by Jiang Yuan, the total number of units and individuals with these printers should not be many…"

Wang Chuanxing obediently took notes while listening. These were things he went to the local area on a business trip to track down and investigate.

Like an old father, Liu Jinghui warned earnestly, turned around, and said to Jiang Yuan: "Actually, if you are not in a hurry, you can also use an undercover agent. Young people like Wang Chuanxing also know how to use the Internet to contact the other party for a while, and then If you have been undercover for a year and a half, it is still possible to figure out the other party's entire network."

Wang Chuanxing trembled when he heard this, and said hurriedly: "Liu Chu, I will do a thorough investigation when I go to Chiyong. There is no need for an undercover agent..."

"If the criminal you are tracking is indeed a purchased electronic template, it means there is someone behind him, but it is difficult to continue arresting him." Liu Jinghui expressed deep regret.

"No, no, I'll try my best to squeeze him out," Wang Chuanxing's vest had begun to sweat.

It is indeed risky to volunteer. Looking at the conference room, there are already 21 members of the Jiang Yuanzhi case team. It is indeed a scale where one or two can be released as undercover agents.
