After Cui Qishan agreed with Liu Jinghui's plan, he went directly to the person in charge of the office without reporting it to Tao Lu. He then visited several criminal police brigades one by one and made a few calls to colleagues in the security detachment and other units.
There is a clear distinction between police undercovers, special agents and eyes and ears. Among them, undercover agents are the most noble and are rarely seen in ordinary cases. There are differences between special agents and agents outside the establishment, and the use of the former is quite strict.
, so everyone doesn’t like to use it.
More often than not, because the police have been working for a long time, they naturally get to know some marginalized people, exchange some phone numbers, and ask questions when necessary.
Some police officers even skip the step of exchanging phone numbers. They will specially select some of the stupid ones. There is no doubt that such people do exist and they are quite easy to find. Then, you just need to pay close attention to them.
For example, a criminal police officer can select one or several stupid thieves. Because they are stupid thieves with poor personal abilities, they often like to form teams. Then it will take a little time to master the behavioral habits of the stupid thieves. For example
Some thieves like to post some blessing words or pictures on their WeChat Moments before committing a crime, and some even include their location. Once they are there, they can catch the person and not run away.
When arresting, you can deliberately miss the stupid thief, allowing him to escape "luckily", and then you can regroup after calming down.
For a particularly useful stupid thief, if you find it increasingly difficult to form a team, you can arrest him once and throw him to the detention center to expand your network of contacts.
All in all, different police officers have different working styles. Cui Qishan has worked in the criminal police detachment for so many years. Even if he doesn't know the specific details, he still has some understanding of the boundaries of his colleagues' capabilities.
He just talked about what he could talk about, and he didn't try to cover everything.
He just needs to let out the wind, not create a hurricane.
At the same time, Jiang Yuan made a special trip to the map reconnaissance detachment, but found nothing.
The larger the city and the larger the branch, the stronger the map detective force will be, the equipment will be updated, and the personnel will be more capable.
Jiang Yuan has LV6's map detective - trajectory analysis. In theory, it is possible to use existing city surveillance videos to track the location of the suspect. However, precisely because Jiang Yuan has this skill of LV6, he has been able to track the location of the suspect very early.
I am keenly aware that this trick is unlikely to be used this time.
At least it won't be used in the early stages of pursuit.
Because the suspect does not have any particularly strong anti-reconnaissance capabilities, nor does he have excellent anti-reconnaissance conditions. The suspect jumped out of the police station wall at two o'clock in the morning, unlocked a shared bicycle, and escaped. And to
In the early morning on the streets of Beijing, tracking a suspect riding a shared bicycle does not require LV2 level skills.
Even if the suspect walks around the streets and engages in some tricks, it is impossible to avoid the investigation of the picture detective in such an environment. Under these conditions, perhaps the AI function built into the software can target fugitives.
There is no shortage of talents in the Beijing Bureau, and there are also excellent picture investigators. Before Cui Qishan and Tao Zhi called Jiang Yuan, they would definitely find the most powerful picture investigators.
However, no matter how good the map detection expert is, he can't stop the suspect from running straight into the wild.
Without monitoring, a relatively short section is fine, but if it is too long, it will be difficult to judge the trajectory. If it is a vehicle, there may be hope, but if it is on foot, it will only be more difficult.
Jiang Yuan estimated that the suspect should have stayed in a park that night.
There is water and toilets in the park, and there are few surveillance cameras and even fewer Internet connections. Of course, if the suspect is more cruel to himself, there will be more ways to hide him. Stay like this for a night, and wait until the morning rush hour the next day.
There are still many ways to escape by changing your route.
As the saying goes, mice follow their own paths, and snakes follow their paths. Jiang Yuan is not sure what the situation is like in the capital, but in Qinghe City, local thieves who are familiar with the situation want to leave the city and just find a bus outside the bus station.
Just stop at the bus stop. This is one of the reasons why many bus stations emphasize that they do not allow outside solicitation.
Methods such as bypassing train stations are common secrets in small cities.
When Jiang Yuan came back from the map reconnaissance detachment, he saw that Cui Qishan and others were already making relevant arrangements.
Looking at the time, 12 hours have passed since the suspect escaped.
"If he keeps running, he might have left the city." Cui Qishan felt a little uneasy.
"As long as you haven't gone abroad, it's the same." Liu Jinghui waved his hand, giving Cui Qishan some emotional value, and then said to Jiang Yuan: "Jiang Yuan, have you been to the next province?"
Jiang Yuan shook his head: "I haven't been there."
"I've never been here before." Liu Jinghui looked at Cui Qishan again.
Cui Qishan smiled bitterly: "I know some of them, but they have all been offended."
"Nothing wrong." Liu Jinghui smiled and said, "Then continue to use Jiang Yuan's banner? Or is there someone else in your unit who can work with you?"
"If it's Captain Jiang, the effect will be better." Cui Qishan quickly explained to Jiang Yuan: "Captain Jiang, the database of our map detective here is not related to the one in the next province. You must be able to say hello.
If so, that would be the best.”
"Is it useful if I say hello?" Jiang Yuan knew what Cui Qishan meant, but he was a little hesitant.
"It must be useful to call you, it's so useful!" Cui Qishan said with a smile: "With your current reputation, everyone will definitely be willing to make it easier if they know it is your case."
Many databases in domestic systems, or high-tech applications, are based on provinces. There is historical evolution here, and it is also related to funding and management.
When we started construction back then, preparations were made at the provincial level or even lower levels, and there were very few national databases.
The result is that the data of Province A and the data of Province B are independent of each other. A few years ago, DNA and fingerprint data were independent of each province, and suspects with important cases were also submitted to the ministry.
Go and distribute it to various provinces.
Nowadays, some provinces are interconnected, but many provinces are still not fully connected to the grid. In this way, if someone goes to the next province and you want to check the data, you will not be able to find it directly. You have to find the corresponding data in the next province.
Let the department check.
Although the ministry can help with the drafting of documents and investigations, as long as they are not foreign guests, no, if they are the European Union or Americans, they should have a better understanding of the limitations of state rights.
All in all, even if the police encounter this kind of situation, communication between people is ten thousand times better than a cold official letter.
Jiang Yuan didn't mind using his personal influence. As an expert, reputation is also part of his strength, so he said: "It's okay to call me, but I don't know the person and I don't have a phone number."
"Don't worry, I will make arrangements later. When the phone is called, you can just say a few words. Don't worry, there are no other men in our Beijing Bureau who can do this." Cui Qishan said,
The whole person felt much more relaxed.
Anyone who has ever been a criminal police officer knows that there are two types of criminal police officers who are good at doing business. One is the iron-legged type, who relies on hard and outstanding efforts to bravely overcome all difficulties. The other is the relationship-based criminal police, most of whom have seniority.
The veteran criminal policeman has acquaintances outside the city and even the province.
The acquaintances here can't just be acquaintances, they must recognize each other and be able to finalize something with a phone call.
Compared with the former, relationship-based detectives are naturally more scarce. Many detective captains of criminal police teams are of this type.
Cui Qishan is neither an iron-clad nor a relational person, because he is not essentially a criminal policeman who is good at business.
But as long as Cui Qishan has Jiang Yuan by his side, that's enough.
