Chapter 1162

Airport and high-speed rail station security is comprehensive, and they basically all have relatively independent branch bureaus or police stations with sufficient manpower available.

Jiang Yuan first called Wang Sheng, the detachment leader of the Meiyang City Criminal Police Detachment, and then contacted the command center to have both sides coordinate police forces and resources.

Neither Jiang Yuan nor Liu Jinghui felt that Ren Kuangshan would choose these two places. The risk was too high; since he even knew to prepare a motorcycle in advance to escape, why would he challenge such a high-difficulty task?

Whatever remains—be it ordinary train stations, bus stations, car rental agencies, ride-sharing services, or even buying a new car, or even stealing or robbing a car—is much easier than planes and high-speed rail.

And the resources required to investigate these places are not on the same order of magnitude.

On the command center side, the person responsible for contacting Jiang Yuan was Wang Chuanxing from the Changyang detention version; he was stunned upon hearing Jiang Yuan's request. Anyone who had coordinated related work for a few days would know how much workload and political resources were required by this request of Jiang Yuan's.

However, the benefit of just doing the work without being in charge is right here: you don't have to be responsible for asking for favors everywhere; you just open your mouth and ask.

Moreover, because Jiang Yuan's request was extremely reasonable, even if the command center had to grit its teeth, it could only find a way to get money for him.

Subsequently, Yu Wenshu called back to follow up and asked, "You've already checked all the surrounding gas stations; do you still need to check for cars? He has to refuel if he drives, right?"

Jiang Yuan smiled and said, "I had this thought before, but... the scope we investigated earlier was only gas stations within a 300 to 400-kilometer radius to the northeast, which was calculated based on the fuel tank of the motorcycle he was riding. But if he changes to another car, that fuel tank won't just run for 300 to 400 kilometers; there are plenty of cars that can run 700, 800, or 1,000 kilometers... Of course, if there's no reaction at the vehicle checkpoints, it's difficult for him to rent a car, but it's hard to say. I have to check it once to be at ease..."

"You're right, you're right." Yu Wenshu nodded repeatedly and added, "Then I'll ask all the people Ren Kuangshan knows, all his friends and relatives, to avoid him borrowing or buying a car or something."

"That's right, you're thinking thoroughly." Jiang Yuan agreed. These were investigation ideas that veteran criminal police had been using for decades, and he didn't need to teach people bit by bit. In fact, just using these old routines to catch people, any police officer with three beans could beat him.

Seeing Jiang Yuan follow advice, Yu Wenshu felt a bit more relaxed and added, "The car situation is more complicated. Although the probability is not high... I think we can do this: the command center can organize a team specifically for the investigation, especially the underground car market, second-hand car dealers, including repair shops. In addition, including ride-sharing, Huolala, and the nearby service areas and truck yards, we can screen them all. Ren Kuangshan should be someone who understands cars. Calculated this way, he might also buy smuggled cars, or even scrapped cars, cloned license plate cars, etc. One team is probably not enough, but if the Meiyang Municipal Bureau participates, we can start the work first and strengthen it while doing it..."

Smuggled cars are cars that are smuggled; scrapped cars just reached the age limit, it's not that they can't be driven, and cloning a plate makes it easier to hide. These all belong to illegal vehicles; not only will they not go through regular channels, but the sales locations and personnel will also stay out of sight, making it more convenient for fugitives.

For an ordinary person who has committed a crime, buying this kind of car temporarily is actually full of difficulties, but if prepared in advance, especially for an old driver like Ren Kuangshan, he is not easily cheated when buying a car, and even if the car has problems on the road, he can handle it temporarily, so there's no need to worry too much.

This is exactly the truth of what the ancients said about skills not being a burden; especially real, solid technology, even if not used when running away, is an advantage, and the police have to consume resources to guard against it.

Jiang Yuan agreed repeatedly. These were parts he hadn't considered carefully, and also parts he wasn't good at. If he were in charge himself, by this step, it would be about time to invite Xu Taining to appear.

But the stall laid out by the Changyang Municipal Bureau this time is much larger. Without a clear target, one cannot conduct screening on a national scale. After all, the pursuit of the Two Wangs back then mobilized more than 30,000 military and police, more than 100,000 militiamen and masses, and one helicopter. That was in '83, just over three years after the counterattack against Vietnam. Converted to today, it would be equivalent to mobilizing a province's mobile police force, plus a heavy combined arms brigade, and one J-20.

"The situation at bus stations and train stations is also very complicated. How do you plan to check?" Yu Wenshu asked Jiang Yuan again.

Jiang Yuan smiled and said, "Our cold case task force only has these few people... I plan to focus on screening a few stations."

"You really have clues?" Yu Wenshu became excited all of a sudden. Now, as long as there is a tiny clue, a large amount of manpower and funds can be saved. At this time, funds can be ignored for now, and every bit of police force saved can be used somewhere.

"I watched the surveillance before. After Ren Kuangshan left the Shipopo gas station, he disappeared after passing only a few surveillance points. At the time, I thought the subsequent surveillance didn't scan him, or he chose some remote route. Now considering, if he abandoned the car, connecting several lines, the closest are 3 counties, two train stations, and 6 bus stations."

Jiang Yuan said it easily, but to give this judgment was not easy at all. This is what Liu Jinghui said, it is a conclusion based on proof of absence, it is a conclusion reached after watching a large amount of surveillance that the subsequent surveillance didn't miss him, but that he abandoned the car, and then, based on the last location where he appeared, the scope was delineated.

Every layer of judgment in this is also probabilistic. For every extra layer, the probability is much lower.

"Good, good, good. As long as you have a train of thought, it's fine." Connecting two points into a line and using this as a basis to search nearby train stations is indeed a plan.

Yu Wenshu certainly approved of Jiang Yuan's idea, but the excitement cooled down quickly because this was a train of thought based on layers of assumptions.

Yu Wenshu sighed inwardly, thinking that even for Jiang Yuan, reaching this step was very difficult.

Yu Wenshu looked up at the time again; it had been over 100 hours since the case occurred, and under such large-scale mobilization, if no results were produced within two days of persisting for seven days, the resources of the special task force would plummet, and the pressure would only increase.

Jiang Yuan ended the call, but his excitement value was slowly increasing.

"Regarding the car, Detachment Leader Yu took it over proactively." Jiang Yuan turned his head and said to Liu Jinghui, "We will focus on checking the train stations and bus stations in these three counties."

"I'll go find the surveillance!" The one who answered was Wang Chuanxing.

"Wait a moment." Liu Jinghui called him to stop and said, "For train stations and bus stations, you can't just check inside the station. Ren Kuangshan has a certain ability to counter-reconnaissance. He mostly understands the situation inside train stations and bus stations, and it's very likely he will find a way to bypass and get in. The management of small train stations in these counties is not strict, especially bus stations. There are many situations where people get on the bus outside the station, so you have to guard against it."

The conductors on green-skinned trains are busy supplementing tickets for passengers all day long, so you can know how many people are getting on the train by bluffing. This is just for ordinary people who want to save money; slightly experienced criminals are even more aware of the loopholes in this area. In fact, the train police on trains have always been strong contenders for catching fugitives, and some have caught hundreds of people in a year, thus winning the title of Second-Class Hero.

Wang Chuanxing waited a bit longer, and seeing that Jiang Yuan had no other orders, he immediately went to make a call.

He had to contact the command center first, then contact the criminal police brigades of the three counties, and maybe even contact the local train police brigade or the station police station. Just like before, in addition to official surveillance, the local criminal police had to collect surveillance videos around the station.

The police officers of Jiang Yuan's cold case task force were also scattered. Two train stations, six bus stations, sending 4 people to each side would require 32 people. 4 people are actually not enough; a station has many doors, and there is such a large area, all kinds of corners and edges. The police officers sent must at least walk through them, otherwise, a supermarket directly connected to the station, or an open fence, could make everyone's work go to waste.

Jiang Yuan stayed in the image investigation department, first watching the previous surveillance videos again to confirm his judgment.

After finding Ren Kuangshan at the Shipopo gas station, one could see the footage of him leaving the gas station and crossing two intersections, but after being filmed for the last time at an intersection a few kilometers away, Ren Kuangshan disappeared.

Obviously, he should have entered the mountains after passing this intersection, but in terms of the surrounding environment, there are many roads that mountain motorcycles can take. Who knows when he went down the mountain and then took a normal route; even if surveillance filmed him, it couldn't be checked.

But if starting from here, judging that he was preparing to abandon the car and change to other means of transportation, there were actually not many routes to choose from.

Theoretically, one could collect surveillance from all these directions and then investigate, but it is actually limited to theory. This volume is too large, and some routes also involve crossing cities and provinces. Even if the ministries come forward to coordinate, the various procedures will take a lot of time.

Just during the time of re-watching, some surveillance videos from Zhuyuan County, which is the closest, had already been sent back.

Jiang Yuan opened his paper notebook, recorded a bit, then opened the software and started watching.

Work such as surveillance video format conversion, sorting, etc., naturally had people helping to do it.

This look lasted directly until late at night.

When Jiang Yuan felt hungry, he looked up again, and the computers in the room were still half-lit.

"If there's nothing, go rest." Jiang Yuan stood up and said, "It won't be finished today either."

After a while, someone said, "Not going back. The wife is asleep. Going back to the house now is just looking for a scolding."

"No wife."

"No house."

Everyone gave simple answers one after another.

Jiang Yuan couldn't help but look at Liu Jinghui next to him: "You're not going back either?"

"I'm also thinking." Liu Jinghui tapped the table with a pen.

Jiang Yuan touched his stomach, suddenly missing Wu Junhao a bit. He went on a mission, and even the meat sandwich was gone.

"Get some hot pot." Jiang Yuan said to Wang Chuanxing, and prepared to sit down and continue watching the video.

"Ready, can eat anytime." Wang Chuanxing touching Jiang Yuan was more familiar than touching a police dog.

"Then let's eat." Jiang Yuan thought about it, and simply asked people to move the hot pot in, placing it in the hall of the image investigation department, eating hot pot while watching the big screen.

The steaming hot pot lingered in the carefully maintained information research and judgment center of the Meiyang City Image Investigation Detachment, expressing the homesickness of all police personnel.

On the wall opposite the hot pot, several screens were playing videos at normal speed.

Jiang Yuan watched the screen, and Wang Chuanxing was responsible for blanching the vegetables.

He first blanched some lettuce produced by the Jiang family ranch, then blanched the beef from the Jiang family ranch, focusing on health.

Jiang Yuan ate while watching, his brain still turning non-stop.

Liu Jinghui couldn't watch it anymore and said, "How about resting for a while, and watch after eating."

"Should sleep after eating." Jiang Yuan glanced at Liu Jinghui: "You are a bit too ruthless."

Mu Zhiyang also persuaded from the side: "Actually, it's not that much time, how about first..."

"Stop for a moment." Jiang Yuan reached out and shouted.

Wang Chuanxing, who was blanching meat, stopped and asked, "Not eating the beef?"

"I mean the video, the position just now." Jiang Yuan stood up and pointed at the big screen.

The image investigation police officers who were eating hot pot were stunned, followed by a burst of chaos.

"It's right here." Jiang Yuan pointed at a group of people crossing the road, watched it repeatedly three times, then tapped with his hand: "This one in black clothes and black pants, sneakers, wearing a mask, is Ren Kuangshan. He left by train. Check the train schedule."

Beyond everyone's surprise, Mu Zhiyang was dumbfounded. Was it really just that little bit off? Did I miss many opportunities?
