Chapter 961

After Cui Cui Qishan approved Liu Liu Jinghui's plan, he did not report it to Tao Lu, but went directly to the person in charge of the office, then strolled through several criminal investigation brigades one by one, and took the opportunity to make a few calls to colleagues in units such as the Public Security Detachment.

The police distinguish very clearly between undercover agents, special informants, and ears/eyes. Among them, undercover agents are the most prestigious and are rarely seen in ordinary cases. Special informants and ears/eyes have a distinction between those within the establishment and those outside of it; the use of the former is still quite strict, so everyone does not like to use them.

More often, it is that after being a police officer for a long time, one naturally gets to know some marginal figures and exchanges some phone numbers, which can be asked about when needed.

There are also police officers who even skip the step of exchanging phone numbers; they will specifically select some of the stupider ones—do not doubt it, there really are such people, and they are quite easy to find—and then, you just need to keep a close eye on them.

For example, a criminal police officer can select one or several stupid thieves. Because they are stupid thieves, their personal abilities are relatively poor, and they often like to form teams, so one just needs to spend a little time to master the behavioral habits of these stupid thieves. For instance, some thieves like to post prayers or pictures on their social media circles before committing a crime, and some even include location tags; once you swipe to them, catching them is a sure thing.

When making an arrest, one can intentionally let the stupid thief slip away, allowing him to "luckily" escape, and after he calms down, he will form a team again.

For a particularly useful stupid thief, when you find that he is becoming increasingly difficult to form a team with, you can also arrest him once and throw him into the detention center to expand his network of contacts.

In short, different police officers have different working styles. Cui Cui Qishan has worked in the Criminal Investigation Detachment for so many years that even if he doesn't know the specific details, he still has some understanding of the capability boundaries of his colleagues.

He says what he can, without seeking to be exhaustive.

He only needs to release the wind; he doesn't need to create a hurricane.

At the same time, Jiang Yuan made a special trip to the Image Investigation Detachment, but returned empty-handed.

The larger the city and the larger the branch bureau, the stronger the image investigation power, the more updated the equipment, and the stronger the personnel's abilities.

Jiang Yuan has LV6 Image Investigation—Trajectory Analysis. Theoretically, he can use existing urban surveillance videos to track the suspect's location. However, precisely because Jiang Yuan has this skill at LV6, he keenly realized very early on that this trick would not be of much use this time.

At least it wouldn't be useful in the early stages of the pursuit.

Because the suspect does not have any particularly awesome anti-reconnaissance capabilities, nor does he have awesome anti-reconnaissance conditions. The suspect jumped over the police station wall at two o'clock in the morning and unlocked a shared bicycle to flee. And to keep an eye on a suspect riding a shared bicycle on the streets of the capital in the early morning hours, one does not need LV2-level skills.

Even if the suspect walks through streets and alleys and performs some flashy operations, it is impossible to avoid image investigation under such circumstances. With these conditions, perhaps the software's built-in AI function could lock onto the fugitive.

And the Beijing Bureau is not short of talent, nor is it short of awesome image investigators. Before Cui Cui Qishan and Branch Chief Tao called Jiang Yuan, they must have had the most awesome image investigation experts look at it.

However, no matter how awesome an image investigation expert is, they cannot stop a suspect from heading straight into the wilderness.

Without surveillance, a relatively short segment is fine, but if it's too long, the trajectory is very difficult to judge. If it were a vehicle, there might be hope; if on foot, the difficulty would only be greater.

Jiang Yuan estimates that the suspect should have spent the night in a park that evening.

Parks have water and toilets, and the number of surveillance cameras is small, with even fewer connected to the network. Of course, if the suspect were even more ruthless to himself, there would be many more ways to hide. After enduring the night like this, he could change his tracks and go out during the morning rush hour the next day; there are still quite a few ways to escape.

As the saying goes, rats have rat paths and snakes have snake ways. Jiang Yuan is not quite sure what the situation in the capital is like, but in Qinghe City, local thieves familiar with the situation who want to leave the city can just find a bus boarding point outside any bus station. This is also one of the reasons why many bus stations emphasize that soliciting passengers outside the station is not allowed.

Ways to bypass train stations and the like are an even more common secret in small cities.

When Jiang Yuan returned from the Image Investigation Detachment, he saw Cui Cui Qishan and the others already making relevant deployments.

Looking at the time, 12 hours had already passed since the suspect escaped.

"If he keeps running, he might have already left the city." Cui Cui Qishan was slightly uneasy.

"As long as he hasn't run out of the country, it's all the same." Liu Liu Jinghui waved his hand, providing Cui Cui Qishan with some emotional value, then said to Jiang Yuan: "Jiang Yuan, have you been to the neighboring province?"

Jiang Yuan shook his head: "I haven't been there."

"I haven't been here either." Liu Liu Jinghui looked at Cui Cui Qishan again.

Cui Cui Qishan gave a wry smile: "I have acquaintances. But I've offended them all."

"No problem." Liu Liu Jinghui smiled and let it pass, saying: "Then we'll continue to use Jiang Yuan's banner? Or does your unit have anyone else who is suitable?"

"If it's Team Leader Jiang, the effect would be better, right." Cui Cui Qishan hurriedly explained to Jiang Yuan: "Team Leader Jiang, our image investigation database and such here are not connected to the neighboring province. If you could put in a word, that would be the best."

"Is it useful for me to put in a word?" Jiang Yuan knew what Cui Cui Qishan meant, but was a bit hesitant.

"It's definitely useful for you to make the call, it's too useful!" Cui Cui Qishan said with a flattering smile: "With your current reputation, knowing it's your case, everyone will definitely be willing to make things convenient."

Many databases within the domestic system, or the application of high-tech, are based on the province as a unit. This has historical evolution and is also related to funding and management.

When everyone started construction back then, they were all prepared based on the provincial level or even lower levels; nationwide databases are few and far between.

The result is that the data in Province A and the data in Province B are independent of each other. Several years ago, even DNA and fingerprint data were independent in each province. Suspects in important cases were submitted to the Ministry, and then issued to each province.

Nowadays, some provinces are interconnected, but many provinces still have not fully merged into the network. In this way, if a person runs to the neighboring province, if you want to check the data, you cannot check it directly; you must find the corresponding department in the neighboring province to check.

Although the Ministry can help with official letters for investigation, anyone who is not a foreign guest knows—no, if it were the EU or Americans, they should understand the limitations of state power even more.

In short, even for police officers, encountering this situation, human-to-human communication is ten thousand times better than cold official letters.

Jiang Yuan doesn't mind using his personal influence. As an expert, reputation is also part of strength, so he said: "I have no problem making the call, but I don't know anyone, and I don't have their phone numbers."

"Don't worry, I'll arrange everything when I go back. When the call goes through, you just need to say a few words. Don't worry, our Beijing Bureau doesn't have anything else, but we have plenty of men who know how to handle this." As Cui Cui Qishan spoke, he felt much more relaxed.

Anyone who has been a criminal police officer knows that there are two types of criminal police officers who are good at business. One is the "iron-soled" type, who relies on arduous and excellent efforts to bravely overcome all difficulties. The other is the "relationship-based" criminal police officer, most of whom are old criminal police officers with long seniority who have acquaintances outside the city and even outside the province.

The acquaintances here cannot just be people you know; they must be people who mutually recognize each other, to the extent that one phone call can settle a matter.

Compared to the former, relationship-based criminal police officers are naturally scarcer. Many criminal police captains are of this type.

Cui Cui Qishan belongs to neither the iron-soled type nor the relationship-based type, because essentially, he is not a criminal police officer who is good at business.

But as long as Cui Cui Qishan has Jiang Yuan by his side, that is enough.
