Police Chen Shu

At night, an ordinary Satana 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 doesn't have a vehicle in his name. Well, Zheng Amei doesn't have one either." Huang Mao pointed out the police officer quickly, speaking without raising his head, with a slight hint of pride in his tone.

"Where are the traffic violation records?" Chen Shu added a search range.

Jiang Hai's eyes lit up and he thought this was a wonderful little investigative method. Unfortunately, he didn't have pen and paper to record, otherwise he would have carried forward the spirit of the top student in the police academy.

"Uh" Huang Mao paused. He could think of checking the vehicle in the suspect's name, but he didn't really go into detail enough to even go through the other party's traffic violation record.

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

"Yeah" Chen Shu thought about 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 followed them into the underground parking lot of the hotel where they were staying in a Mazda car.

Therefore, the hotel's surveillance video must contain records from that time, which can be traced back to their license plate numbers, and then the traffic police's vehicle tracking system can be used to trace the two people's traces to narrow the search scope.

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

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

Zheng Jie and his accomplice in the peaked hat were clearly photographed.

"The last place they appeared was on Lai Fu Road. This is a commercial street, and it will take a lot of time to find someone. Now that Zheng Amei has been arrested, and time is so tight, I'm afraid that if there is a slight delay, once they can't contact Zheng Amei, He ran 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 car, with a young man wearing a peaked cap sitting next to him.

Chen Shu's expression was calm. Since he could determine the general range, he was not worried about finding the person.

He drew a large rectangle with both hands and said: "Chen Chuan, I remember that your criminal technology has a machine that searches for specific mobile phone signals on site? Well, it's a pretty big iron box, put on headphones, and carry it I can find my mobile phone on the street.”

When Chen Shu said he was going to Burma to fish for people, Chen Chuan secretly took this mobile machine that could search for specific mobile phone signals at close range and followed him out of the country.

Although it is a piece of equipment that has been eliminated in the unit, it is really convenient for searching mobile phones.

The iron box is actually a radio transmitting device. The principle is to use the advantage of high local power to bypass the operator's official base station by disguising itself as a base station, thereby receiving specific mobile phone signals.

The technology is not very advanced, and it was widely used for fraud in the early years. For example, the overwhelming SMS fraud used this technology to achieve mass messaging.

At its peak, a criminal suspect only needed one person, walking around the streets with a big bag containing a fake base station, and could receive two thousand yuan an hour.

Note, it's one hour.

Why is it calculated by hours?

Not only to highlight the high salary of 2,000 yuan per hour, but more importantly, he may have to be knocked on the head by the police uncle in the second hour.

But having said that, in the first year after this technology came out, it really made a small fortune for those scumbags who took advantage of others and engaged in fraud.

There is nothing we can do about it. The lag in police handling of cases is like this. Similar to the later online loans, P2P, virtual currency, etc., before the Chinese government reacted and took action, it was indeed one of the ways for the people at the bottom to stand up.

Chen Chuan, who was sitting in the passenger seat, picked his nose and said nonchalantly: "The old technology from more than ten years ago is only effective for mobile phones with 2G networks and has been eliminated long ago. But after all, it still needs to be officially It can only be used with approval.”

As he said that, he turned his head with some difficulty, glanced at Huang Mao who was sitting in the back row, and said rudely: "Huang Mao may not have this authority, how about we go back to the unit to write an application report first, and then go through the process. ?”

The use of high-tech investigative methods like this usually has to be approved by the leaders of the brigade and detachment, as well as the famously strict legal officials who monitor the leaders.

After completing the above customs clearance, you still have to go in person to the leader on duty at the Municipal Bureau to explain the situation and obtain the other party's consent. Not only does it take a long time, but it is at least not short.

Chen Shu, who was sitting in the driver's seat, tapped the steering wheel with his knuckles and said slowly: "It's okay, I have the WeChat account of the cap."

In the underground parking lot of the hotel at that time, Chen Shu, in line with his usual thinking of not letting these swindlers go to waste, just added the WeChat account of the man wearing a peaked cap, and then transferred a few hundred dollars.

Chen Shu's approach does not mean that he is afraid of these social prostitutes, but it is a good deal to spend a few hundred yuan to eliminate unnecessary troubles that may occur during their vacation in Yun Province in the future.

After all, thieves don't get away with it, so it's easy to stop them by charging them a small amount of money.

There are also people who wander around the edges of crime, but they are the favorite source of indicators for the police investigating the case. This is how the so-called informants come, and they have to be maintained.

Among the methods used by the police to handle cases, bribery of informants is the most convenient method, bar none.

Lead fees can be reimbursed to the unit. According to the relationship between supply and demand, the standards vary every few years, but overall, they are still on the high side.

If the reimbursement is low, for example, drug abuse, one person can be reimbursed 1,000 yuan; if the reimbursement is high, for gun-related cases, the minimum reimbursement is 30,000 yuan, with no upper limit.

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

In this kind of place, drug-related crimes are much more abundant than in other parts of China. Even if some of them are leaked from their fingers, there will still be plenty of surplus.

In recent years, Dongzhou City's drug crackdown has become somewhat fierce. The most intuitive manifestation is that the price of powder has risen to 8,000 yuan, and demand exceeds supply.

From a side perspective, things are more valuable when they are scarce. There are fewer things, which means that the number of people doing this business is slowly decreasing, and the police in Dongzhou will not be able to meet the quota.

Out of desperation, some policemen go across cities or even provinces to catch drug addicts.

You know, taking drugs sounds like a vicious crime, but in fact it can only be regarded as an administrative violation, similar to drunken fights, prostitution and gambling.

Under such comparison, as the former number one person in the branch's security crackdown, it is not unusual for Chen Shu to subconsciously keep an informant across provinces in case of emergencies.
