Chapter 768: Raising an Informant Across Provinces

At night, an ordinary Sartana car blended into the night, slightly hazy under the dim street lights.

"License plate." Chen Shu sat in the driver's seat, his voice as calm as water.

"Zheng Jie has no vehicles under his name. Well, Zheng Amei doesn't have one either." Huang Mao quickly clicked on the police communication, speaking without raising his head, with a slight pride in his tone.

"What about traffic violation records?" Chen Shu added a search range.

Jiang Hai's eyes lit up, thinking that this was a wonderful little investigation trick, but it was a pity that he didn't have paper and pen to record, otherwise he would definitely carry forward the spirit of the police academy's academic bully.

"Uh" Huang Mao paused, he could think of checking the vehicles under the name of the criminal suspect, but he didn't really go into it so much that he had to look through the other party's traffic violation records.

After searching for the software entrance in the application menu of the police communication for a long time, he finally clicked on the right place, and Huang Mao said: "There is a driver's license, but there is no penalty record, and there is no related car."

"Well" Chen Shu recalled what happened in the middle of the night a few days ago.

When Zheng Jie and another man blackmailed Zhu Yiba and Chen Chuan that day, they drove a Mazda sedan and followed them into the underground parking lot of the hotel where they were staying.

Therefore, the hotel's surveillance video must have records of the time, from which their license plate numbers can be traced back, and then the two people's whereabouts can be traced back through the traffic police's vehicle tracking system to narrow the search scope.

Chen Shu asked Huang Mao to contact Ma Rongcheng, who was on standby in the brigade, and asked him to go to the hotel to retrieve the license plate of the vehicle driven by Zheng Jie that night.

About an hour later, Ma Rongcheng successfully obtained the license plate, and then used WeChat to send back the driving trajectory of the Mazda and the high-definition photos taken by the checkpoint.

Zheng Jie and his accomplice were clearly photographed.

"The last place they appeared was Laifu Road. This is a commercial street, and it will take a lot of time to find someone. Now Zheng Amei has been arrested, and time is so tight. I am afraid that if there is a slight delay, once they can't contact Zheng Amei, they will run away." Huang Mao glanced at the phone, then turned the screen upside down and handed it to Chen Shu.

Chen Shu glanced at his phone. On the screen, Zheng Jie was still driving the old black Mazda sedan, and a young man wearing a peaked cap was sitting next to him.

Chen Shu's expression was calm. Since he could determine the approximate range, he was not afraid of not finding the person.

He gestured with his hands to form a large rectangle and said, "Chen Chuan, I remember that your criminal technology department has a machine that can search for specific mobile phone signals on the spot? Well, it's a big iron box. Put on headphones and carry it to the road to find the phone."

When Chen Shu said he was going to Myanmar to rescue someone, Chen Chuan secretly took this mobile machine that could search for specific mobile phone signals at close range with him on a trip abroad.

Although it was an obsolete equipment in the unit, it was really convenient for searching mobile phones.

The iron box is actually a radio transmitter. The principle is to use the advantage of high local power to disguise itself as a base station to bypass the official base station of the operator and receive specific mobile phone signals.

The technology is not very advanced. It was widely used for fraud in the early years. For example, the overwhelming SMS fraud was achieved through this technology.

At its peak, the criminal suspect only needed one person to walk around the street with a big backpack containing a fake base station, and he could earn 2,000 yuan in one hour.

Note, it was one hour.

Why is it calculated by the hour?

It is not just to highlight the high salary of 2,000 yuan per hour, but more importantly, he might be arrested by the police in the second hour.

However, in the first year after this technology came out, it really made those scumbags who made money by cheating and fraudulently made a small fortune.

There is no way around it. The lag in police handling cases is like this. Similar to the later online loans, P2P, virtual currencies, etc., before the Chinese government reacted and took action, it was indeed one of the ways for the lower-class people to turn over.

Chen Chuan, who was sitting in the passenger seat, picked his nose and said indifferently: "This old technology from more than ten years ago is only better for mobile phones with 2G networks and has been eliminated long ago. But no matter what, it still needs formal approval before it can be used."

As he said this, he turned his head with some effort, glanced at Huangmao who was sitting obediently in the back seat, and said bluntly: "Huangmao may not have this authority, otherwise we should go back to the unit to apply for a report and go through the procedures?"

Such high-tech investigative methods generally have to be approved by the leaders of the brigade and detachment, as well as the legal officers who are known for their strictness to check for the leaders.

After passing the above customs, you have to go to the on-duty leader of the Municipal Bureau in person to explain the situation and obtain the other party's consent. It takes a long time, but at least it is not short.

Sitting in the driver's seat, Chen Shu tapped the steering wheel with his knuckles and said slowly, "It's okay, I have the WeChat of the man in the baseball cap."

At that time, in the underground parking lot of the hotel, Chen Shu, based on the usual idea that these guys who make money by illegal means should not make a wasted trip, insisted on adding the WeChat of the man in the baseball cap and then transferred a few hundred yuan to him.

Chen Shu's approach was not to say that he was afraid of these social scoundrels, but it was a good deal to use a few hundred yuan to eliminate unnecessary troubles that might occur during their vacation in Yun Province in the future.

After all, thieves never leave empty-handed, so it is easier to let them calm down by collecting a little money.

Also, people who wander around the edge of crime are the favorite indicators of police officers in handling cases. This is how the so-called informants come from, and they have to be kept.

Among the police's methods of handling cases, buying off informants is the most convenient way, no doubt about it.

The clue fee can be reimbursed to the unit. According to the supply and demand relationship, the standard is different every few years, but in general, it is still relatively high.

For example, drug abuse can be reimbursed for one thousand yuan per person; for gun-related cases, the minimum is 30,000 yuan, with no upper limit.

As for the peaked cap, Chen Shu was attracted by the fact that he was from Yunnan Province.

In places like this, drug-related crimes are much richer than other places in China. Even if they are given some from the gaps between their fingers, it is still a surplus.

In recent years, Dongzhou City has been quite fierce in its drug crackdown. The most intuitive manifestation is that the price of powder has risen to 8,000 yuan, and it is still in short supply.

From the side, things are precious because they are scarce. If there are fewer things, it means that the number of people doing this business is also slowly decreasing, and the police in Dongzhou will not be able to meet the target.

Under desperation, some police officers cross cities and even cross provinces to catch drug users.

You know, drug use sounds like a serious crime, but in fact it can only be considered an administrative violation, similar to people's drunken fights, prostitution and gambling.

In this comparison, as the former first person in the branch's public security crackdown, it is not uncommon for Chen Shu to subconsciously raise an informant across provinces in case of emergency.
