National Forensic Doctor

Jiang Yuan read the file on the counterfeit currency case himself, and checked the recent reports from several other places, and then went to find Huang Qiangmin.

"Bureau Huang." Jiang Yuan entered Huang Qiangmin's new office, said hello, and began to report the situation.

Huang Qiangmin felt comfortable just hearing Jiang Yuan call "Huang Bureau". After listening to Jiang Yuan's report, he thought about it and said: "It's not impossible to do economic investigation cases, but "Counterfeit currency cases usually involve a lot of people." Guang is not easy to crack. Not only is it difficult to solve the case, but it also requires traveling to a lot of places to handle the case. "

Jiang Yuan nodded. He didn't think much about this aspect. He thought about it and said, "The people in my team have been quite idle recently."

"Yes, they are all borrowed anyway." Huang Qiangmin's brain was instantly connected to a new channel. Think about it, Jiang Yuan's men are basically borrowed people, whether they are from Changyang City or the newly arrived Guqi City, they don't feel like they can do it for a long time. In this case, they must be used at full capacity. .

Jiang Yuan didn't know where Huang Qiangmin was thinking, so he said about the case: "I want to ask the provincial department to get involved."

"Hey, this is the right idea." Huang Qiangmin slapped his thigh.

The core problem of the counterfeit banknote case is that it involves a huge scope. Although the core of counterfeit banknotes is the counterfeiter, in the early stages of investigation, the counterfeiters are usually not contacted. We can only focus on peripheral cases to arrest some users and counterfeit banknotes. Transporters, trying to reach counterfeiters.

And these users and transporters are obviously circulating throughout the province and even the country.

No counterfeiter would create fake banknotes and sell or use them around his home.

For a small county bureau like Ningtai County, if nothing else, the travel expenses for doing these small cases are a huge expense.

But if the provincial department is asked to take action, no matter what, the provincial department will always provide some funds and resources. Although it may be a drizzle for the provincial department, it is comfortable enough for the county bureau.

Of course, ordinary county bureaus cannot hire the true god of the provincial department. Provincial departments in each province have different work styles. Some focus on public security, some focus on anti-smuggling or anti-drugs, and some focus on maintaining stability... In short, in the eyes of provincial departments, criminal investigation is just a piece of the business puzzle. It's also important, but not the most important.

Speaking of which, even if Huang Qiangmin became Huang Bureau, he would not be able to invite the Shannan Provincial Department, but there would be no problem if he spoke with Jiang Yuan.

That afternoon, Liu Jinghui rushed from Changyang City to Ningtai County.

Working on cases with Jiang Yuan is much more interesting than his usual cases.

Liu Jinghui's rank was too high and he was part of the provincial department. Otherwise, he would rather spend his days working on cases in Jiang Yuan's team.

To be honest, a fourth-level senior sergeant like Liu Jinghui has little potential for promotion. Even if he is promoted to a first-level senior sergeant, as long as he does not have a leadership position, it is actually a false title. The driving force behind Liu Jinghui's meticulous work is the job itself.

If he could... take Jiang Yuan to work together, Liu Jinghui thought he would be very efficient.

As usual, Liu Jinghui was still alone. When he arrived at the Ningtai County Bureau, he met Huang Qiangmin and others, then sat in the conference room with Jiang Yuan and started grading papers.

Liu Jinghui, who is in his forties, has tidied up neatly, and his police uniform is neatly ironed. He is sitting alone at the other end of the conference table. He looks very stylish, and there is no trace of his former glory. Willow's appearance.

Anyone doesn't need to know who Liu Jinghui is, just by looking at the scene in the conference room, they can know that this man is quite extraordinary.

Opposite Liu Jinghui, Jiang Yuan also had a file in front of him. He was teasing the green radish on the table with his hands while looking at it casually.

When Liu Jinghui came over, he had already seen these cases, but he didn't expect Liu Jinghui to come so quickly. In order to facilitate the discussion of the case, everyone simply waited for him.

Liu Jinghui also knew this and turned the pages much faster. Despite this, Liu Jinghui still looked carefully at the places that should be looked at.

Working under pressure is a basic skill in this industry, and there is nothing to dream about.

"Huh... if you look at it this way, the dozen or so counterfeit currency cases that have been reported to the police recently should all be considered a series.

case. "Liu Jinghui closed the last file: "However, not a single case has been closed, which means that not a single criminal suspect has been caught. "

"The people who called the police were all the owners of small restaurants and supermarkets. They were upset after receiving counterfeit money, so they called the police. Not many people really took the 20 yuan seriously. But when the police received the report and went to look for people, they all found them. No, from the monitoring and time point of view, there should be more than one group of people using counterfeit currency. In addition, the counterfeit 20 yuan currency they used seems to have a total of 5 titles... Tang Jia has worked with Liu Jinghui before, The speech is very positive at the moment.

After all, two female police officers were added to Jiang Yuan's backlog of cases. Tang Jia felt that someone was targeting him and was worried that Jiang Yuan was being incited.

Liu Jinghui had just finished reading the dossier, and he also had a strong desire to talk. He nodded slightly and said: "These groups of people should have obtained these counterfeit coins at about the same time. They themselves should be very peripheral members, and they may even be pure consumers. .

Tang Jia: “Are there still consumers for counterfeit currency?

Dong Bing was also familiar with the environment and the colleague Jia Ziyin in front of him, so he asked: "How do you know it was a counterfeit currency obtained at about the same time?"

Liu Jinghui was questioned by two female police officers at the same time, which was equivalent to being courted by 200 male police officers. He patted his belly with satisfaction and said, "Tell each question one question at a time."

Liu Jinghui glanced at Jiang Yuan and saw that he seemed to be listening, and said even more happily: "The judgment at the same time is based on their traveling route. Because not all bosses who received counterfeit money have called the police, and some may We haven’t discovered that there is an element of prejudgment in this, but we may confirm it later.”

Liu Jinghui paused and continued: "Consumers of counterfeit currency should say that counterfeit 20 yuan bills are originally consumer grade. Of course, this is my opinion."

Tang Jia was very cooperative at this time and asked: "Why is it consumer grade?"

"This is the difference between counterfeit 20-yuan notes and counterfeit 100-yuan notes. Users of counterfeit 100-yuan notes tend to spend less money and get change at the same time as payment. This part of the change is his profit. . As for the counterfeit 20-yuan notes, people who use them generally use them directly. After spending dozens of dollars, they give out one or two counterfeit notes, or mix them with real coins and use them. Because the denomination is relatively small, many people will not notice it. ."

“But now very few people use cash.”

Liu Jinghui nodded: "There are still a lot of things to use on the road. Such as gas stations, small restaurants on the roadside, supermarkets, and some small towns. The worse the network, the more elderly people, use cash. The more I see these people, they tend to do this."

Liu Jinghui has multiple reasonings brewing in his mind, and they are all very executable.

At this time, I heard Jiang Yuandao: "Let's take a look at the surveillance."

Liu Jinghui was stunned for a moment, then laughed and said: "These are transactions that occurred in remote areas, and the monitoring was not complete. Moreover, these cases were distributed to several provinces, and the reports in several places were not properly handled..."

"It depends on how many you have." Jiang Yuan smiled and said, "There is always something useful."

"This is too vulgar." Liu Jinghui looked at Jiang Yuan speechlessly and thought to himself, if the case is solved in such a boring way, why should I come all the way here?

The eyes of the two bosses collided, and the younger brothers didn't dare to yell, and they all did their work with low eyebrows.

Soon, several collected surveillance videos were released.

Jiang Yuan and others all focused on the surveillance video.

Liu Jinghui has just arrived, so Wang Chuanxing and others have already seen and screened the surveillance videos here.

At this moment, four videos were also played on the big screen at once, creating a contrast.

"It's one person every time." Tang Jia first pointed out.

"I only use one or two dollars at a time, but the total cost is also very low." Dong Bing was not to be outdone.

"They all wore masks and hats, so they were prepared and knowingly committed the crime."

"If they only use one or two counterfeit coins at a time, wouldn't it be cost-effective to travel to many places a day? The number of police calls seems to be a little less."

Liu Jinghui sighed and said: "So these are the final consumers. Even if they are caught, they probably won't know anything. The core is to find their pattern in order to outline the whole picture."

"What Liu Chu means is that he wants to find more such consumers and then analyze the patterns?" Jiang Yuan summarized briefly.

"It's not entirely dependent on analysis, but there will definitely be more clues and it will be easier to find the counterfeiters. These guys are usually hidden deeper." Liu Jinghui pointed at the video and said: "These guys are constantly scurrying around. , and it’s self-driving, so it’s not easy to find.”

"Use your mobile phone to locate it." Jiang Yuan suggested.

"Where's the mobile phone number?" Liu Jinghui said, asking and answering: "Do you want to find it through the bayonet? It's a bit troublesome. I think I just saw a car with a license plate that was photographed?"

The policeman next to him immediately stood down.

"Here." Liu Jinghui pointed to a corner and said, "I think it's good to locate the phone through the vehicle."

"Okay." Jiang Yuan didn't care which method he used to solve the case. Seeing Liu Chu's active participation, he simply didn't have to worry about it.
