National Forensic Doctor

Airports and high-speed rail stations have complete security checks and basically have relatively independent branches 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 headquarters to ask the two parties to coordinate police forces and resources.

Jiang Yuan and Liu Jinghui didn't think Ren Kuangshan would choose these two places. The risk was too high. He knew why someone who had prepared a motorcycle in advance would take on such a difficult challenge even if he wanted to escape.

The rest, whether it is an ordinary train station, a bus station, a car rental agency and a ride-hailing service, or even buying a new car, or even stealing a car or robbing a car, etc., are much easier than flying or high-speed rail.

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

On the command side, the person responsible for contacting Jiang Yuan was Wang Chuanxing, the Changyang retention version. He was stunned when he heard Jiang Yuan's request. Anyone who has coordinated the related work for several days knows how much work and effort Jiang Yuan's request requires. political resources.

However, the advantage of not being in charge and just working is that you don't have to be responsible for asking for help, you can just ask for it.

Moreover, because Jiang Yuan's request was extremely reasonable, even if the headquarters broke his teeth, they could only defraud the bailiff to get him money.

Later, Yu Wenshu called back for a return visit and asked: "You have already checked all the gas stations in the surrounding areas. Do you still need to check the car? He also needs to refuel when he drives."

Jiang Yuan smiled and said: "I had this idea before, but... the scope of our previous investigation was only gas stations within three to four hundred kilometers in the northeast. That was calculated based on the fuel tank of the motorcycle he was riding. Yes, but if he changes to another car, the fuel tank will not only have a range of three to four hundred kilometers, but also many cars with a range of seven to eight thousand kilometers... Of course, if the vehicle bayonet does not respond, it will be difficult for him to rent a car. But it’s hard to say, you have to check it before you feel at ease…”

"You're right, you're right." Yu Wenshu knocked his head repeatedly, and then said: "Then I will ask all the people Ren Kuangshan knows, including relatives and friends, to prevent him from borrowing a car or buying a car. ”

"That's right, you think carefully." Jiang Yuan agreed. These are the investigative ideas that veteran criminal police officers have used for decades, and there is no need for him to teach people a little bit. In fact, if you just use this old routine to arrest people, any policeman with three beans will beat him up.

Yu Wenshu felt a little more relaxed when he saw that Jiang Yuan was doing good things, and then said: "The situation with the car is more complicated, although the probability is not high... I think it can be done like this. The headquarters can organize a team of people to conduct special investigations, especially It is an underground car market, used car dealers, including repair shops, etc., in addition, including ride-hailing, cargo Lala, as well as the service area and truck yard in front of us, we can sift through it. Ren Kuangshan should be a person who knows a lot about cars. Calculating from this, he may also buy water trucks, even scrap cars, kit cars, etc. One team of people may not be enough, but with the participation of the Meiyang City Bureau, we can start the work first and strengthen it as we go..."

Water trucks are just smuggled cars. Scrapped cars are just old ones, not undriveable. They can be hidden better with a license plate. These are illegal vehicles. Not only will they not go through formal channels, but the sales locations and personnel will also be hidden, making it easier for escapees.

It is actually very difficult for ordinary people to buy such a car temporarily if they commit a crime. However, if they prepare in advance, especially an experienced driver like Ren Kuangshan, he will not be easily cheated when buying a car. Even if there is a problem with the car on the road, he will be able to solve it. It can be dealt with temporarily, so don’t worry too much.

This is exactly what the ancients said about art, especially when it comes to real technology. Even if it is not used, it is still an advantage, and the police have to spend resources to prevent it.

Jiang Yuan agreed repeatedly. These were the parts that he had not considered carefully and the parts that he was not good at. If he were in charge, at this point, it would be almost time to invite Xu Taining to appear.

However, the Changyang Municipal Bureau has set up a lot of stalls this time. Without a clear target, it cannot conduct a nationwide investigation. After all, to hunt down the two kings, more than 30,000 military and police personnel and more than 100,000 militiamen and civilians were mobilized. people, and a helicopter. That was in 1983, and the counterattack against Vietnam had just begun for more than three years. Calculated today, it is equivalent to dispatching the mobile police force of a province, plus a heavy-armored combined brigade, and a J-20.

"The situation at the bus station and train station is also very complicated. How are you going to investigate?" Yu Wenshu asked Jiang Yuan again.

Jiang Yuan smiled and said: "We only have these people in our backlog team... I plan to focus on investigating a few stations."

"Do you really have a clue?" Yu Wenshu suddenly became excited. Now, as long as we have a few clues, we can save a lot of manpower and money. At this time, the funds can be ignored for now, and every bit of police force saved can be used somewhere.

"I watched the surveillance before. Ren Kuangshan left the Shipozi gas station and disappeared after only passing a few surveillance points. At that time, I thought it was because the follow-up surveillance did not catch him, or he chose some remote route. Now think about it, if he abandons the car, the closest lines will be three counties, two train stations, and six bus stations. "

Jiang Yuan said it was easy, but it was not easy at all to make this judgment. This is what Liu Jinghui said. It was based on the conclusion given by the evidence. After watching a lot of surveillance, he came to the conclusion that the follow-up surveillance did not capture him, but that he abandoned the car. Then, based on the final appearance location, demarcated range.

Every level of judgment here is also probabilistic. With each additional level, the probability becomes much lower.

"Okay, okay, as long as you have an idea." Connecting the two points together and using this as a basis to search for nearby train stations is indeed a plan.

Although Yu Wenshu agreed with Jiang Yuan's idea, his excitement quickly cooled down because it was based on layers of assumptions.

Yu Wenshu sighed secretly, thinking that even Jiang Yuan would find it very difficult to achieve this step.

Yu Wenshu looked up at the time and saw that it had been more than 100 hours since the incident. With such a large-scale mobilization, if no results were produced within seven days, that is, within two days, the resources of the task force would plummet. decrease, and the stress will only increase.

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

"Yu Zhi took the initiative to take the car." Jiang Yuan turned to Liu Jinghui and said, "We will focus on checking the train stations and bus stations in these three counties."

"I'll go find the surveillance camera!" Wang Chuanxing answered.

"Wait a minute." Liu Jinghui stopped him and said: "Train stations and bus stations, you can't just check the inside of the station. Ren Kuangshan has certain counter-reconnaissance capabilities, and he knows most of the conditions inside the train stations and bus stations. He is very knowledgeable." You may find a way to get in. The management of small train stations in this county is not strict, especially at bus stations. There are many cases of boarding outside the station, so be careful. "

The stewards on the green trains are always giving passengers extra tickets all day long, so you can know how many people got on the train in disguise. This is just ordinary people who want to save money. Criminals with a little experience know more about this vulnerability. In fact, the policemen on the train have always been strong contenders for the championship of catching fugitives. Some people arrested hundreds of people in a year, and thus won the title of Level 2 Heroic Model.

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

He needs to contact the headquarters first, and then contact the criminal police brigades of the three counties. He may also contact the local police brigade or the station police station. As before, in addition to official surveillance, the local criminal police also need to collect information around the station. surveillance video.

The policemen from Jiangyuan's special case backlog team also dispersed. There are two train stations and six bus stations. If we send 4 people to each side, it will take 32 people. In fact, 4 people are not enough. There are many of them just at the entrance of a station. There is such a large area and all kinds of corners and corners. , the police officers dispatched must at least walk there, otherwise, a supermarket that leads directly to the station or an open fence may ruin everyone's work.

Jiang Yuan stayed on the map and watched the previous surveillance video again to confirm his judgment.

After finding Ren Kuangshan at the Shipozi gas station, you can see the video of him leaving the gas station and crossing two intersections. However, after he was finally photographed at an intersection a few kilometers away, Ren Kuangshan disappeared.

Obviously, he should have entered the mountain after passing this intersection, but considering the nearby environment, there are many roads that mountain bikes can take. He might not know when he would go down the mountain and take the normal route again, and the surveillance camera would capture him. I couldn't find it when I arrived.

But if from here, it is judged that he is planning to abandon the car and switch to other means of transportation, there will not be many routes to choose from.

Theoretically, it is possible to collect all the surveillance in these directions and then investigate, but in fact it is just a theory, the amount is too large, and some lines also involve cross-city and cross-province, even if the ministries and commissions come forward to coordinate, there are all kinds of procedures It also takes a lot of time.

Just during the period of re-watching, some surveillance videos from the nearest Zhuyuan County have been sent back.

Jiang Yuan opened the paper notebook, recorded it, then opened the software and started reading.

For format conversion, sorting, etc. of surveillance videos, there are people who can help you.

At this glance, it was already late at night.

When Jiang Yuan felt hungry, he looked up again and saw that the computer in the room was still half on.

"If you have nothing to do, go and rest." Jiang Yuan stood up and said, "I won't finish watching it today."

After a while, someone said: "I'm not going back. My wife is asleep. Now I'm going back to the house just to scold me."

"No wife."

"No house."

Everyone gave simple answers one after another.

Jiang Yuan couldn't help but glance at Liu Jinghui next to him: "You won't go back either?"

"I'm thinking too." Liu Jinghui tapped the table with his pen.

Jiang Yuan touched his belly and suddenly missed Wu Junhao. He went on a mission and didn't even have to eat the meat buns.

"Let's make some hot pot." Jiang Yuan said to Wang Chuanxing and prepared to sit down and continue watching the video.

"It's ready, you can eat it at any time." Wang Chuanxing touched Jiang Yuan more familiarly than touching a police dog.

"Then let's eat." Jiang Yuan thought about it and simply asked someone to bring the hot pot in and put it in the hall of the picture detective, eating the hot pot while watching the big screen.

The steaming hot pot lingering in the carefully maintained information research and judgment center of the Meiyang City Map Investigation Detachment expresses the homesickness of all police officers.

On the wall opposite the hot pot, several screens displayed videos at normal double speed.

Jiang Yuan looked at the screen, while Wang Chuanxing was in charge of cooking the dishes.

He first rinsed some lettuce from Jiangjia Ranch, and then rinsed beef from Jiangjia Ranch, focusing on health.

Jiang Yuan was eating and watching, his mind still spinning.

Liu Jinghui couldn't stand it anymore and said, "Why don't you take a break and watch again after eating."

"It's time to go to bed after eating." Jiang Yuan glanced at Liu Jinghui: "You are a bit too cruel."

Mu Zhiyang was also advising from the side: "Actually, it's not so short of time, why not..."

"Stop." Jiang Yuan stretched out his hand and shouted.

Wang Chuanxing stopped rinsing the meat and asked, "You don't want to eat Diaolong anymore?"

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

The police officers who were eating hot pot were stunned for a moment, and then there was a commotion.

"It's here." Jiang Yuan pointed at a group of people crossing the road, looked at it three times, and then pointed with his hand: "The one wearing black clothes and black pants, sneakers, and a mask is Ren Kuangshan. He left by train, check the train timetable."

In addition to everyone's surprise, Mu Zhiyang was stunned. It was really just this short? Did I miss a lot of opportunities?
