Chapter 1020 Elements

Investigating hotels and guesthouses in six cities and counties at once, as well as homestays, can be said to be a very large investigation, but for Xu Taining, it is probably just a trickle.

Xu Taining himself has work to do, and it is impossible for him to come here for such a small investigation - if he comes, he must be in charge of the overall investigation. Just investigating the suspect's accommodation location does not really need Xu Taining.

Jiang Yuan disassembled the task to the criminal police teams of the six cities and counties to do it themselves. Involving two provinces and multiple cities, the difficulty of unified action is indeed a bit large. Asking the provincial department to come forward can only communicate, and unified leadership requires a higher-level unit to appear.

At this time, it depends on the capabilities of the criminal police teams themselves.

To be honest, it is actually a very unreliable thing to expect six criminal police teams to be very reliable. An organization is more complicated than a person. From a simple perspective, people will have headaches and fevers, and organizations will also have their change period. As for more complicated states, it will affect work efficiency.

So why is it said that Xu Taining's plan always makes leaders generous? Even the most stingy leaders can't help but be tempted when they hear Xu Taining's plan.

For example, the six-county plan this time does not actually require all six criminal police teams to be reliable.

According to Xu Taining's direction, either the investigation will be empty-the direction is wrong, the criminals did not park their cars in the nearest county or city, they just go back to a fixed nest every time, or drive to the crime scene all night, do not arrive in advance, run away after snatching the children, or sleep directly in the car, etc., and they may not be investigated.

Or, the human traffickers are not so hardworking and simple, then they will not only stay in one place, but will stay in every place in advance, after checking the location, they will carry out the work of stealing and snatching children, and then leave after snatching.

The probability of the latter is obviously higher, and if it is this model, even if the criminal police teams in one or two places are not reliable, the criminal police teams in other places will give answers.

In terms of fault tolerance, Xu Taining's plan is already full. The cost of a single item is not high.

For similar investigations, the biggest expense is travel expenses. Because police do not have overtime pay, units with less money have to pay for their overtime meals. Units with more money only provide one meal, and giving an extra bottle of salty soda is considered a luxury.

Therefore, in summary, the investigation plan that Xu Taining came up with in a short time turned out to be the most reliable investigation direction in the entire case. Of course, it is also the most expensive of all the investigation directions currently.

But Jiang Yuan believes that if Director Xu personally takes action, he must have a more expensive and better plan to propose.

…

Jiang Yuan himself did not go to investigate the hotel. Whether the criminal police do this work or ask the public security brigade for assistance, or ask the police station for help, it is very cumbersome and does not require the technology of the criminal department. It is a traditional skill of the iron-footed.

The other investigation directions are actually similar, including special information, network security or the route of criminals with previous criminal records, etc., and Jiang Yuan is not needed.

Jiang Yuan chose the crime scene in the nearest Qingshi City to see.

Although it was an outdated crime scene and there were no traces of blood or DNA, the first scene is always important. Moreover, Jiang Yuan's crime scene investigation ability is indeed at the top level in China.

Another thing is that Jiang Yuan was also puzzled by the fact that the surveillance did not capture any useful information.

The current Skynet can be said to be very mature. It cannot be said that there are no omissions. There must be a lot of loopholes. After all, it is a government project.

However, generally speaking, the wisdom of criminals who try their best cannot cover the deliberate stupidity of administrative personnel. This is the advanced experience of Chinese social governance since Emperor Taizong of Tang.

It is quite difficult to completely avoid surveillance, even if you have stepped on the point and checked the route in advance. The key is that a human traffickers gang that relies on stealing children to make money has avoided surveillance for six consecutive times. Is this execution ability a bit too strong?

Jiang Yuan took a car for more than two hours before arriving at Lanhua Township, Cuigang County, Qingshi City.

It took only 20 minutes to leave Qingshi City, and only 40 to 50 minutes to enter Cuigang County, but it took a full hour to drive the 30 to 40 kilometers from Cuigang County to Lanhua Township.

The crime scene was in Jide Village, south of Lanhua Township. Locally, this is a large village with a village primary school, a small supermarket and a sports field, and more than 200 elderly people and children living here. People from nearby small villages also come to Jide Village to study and buy things.

But the village itself has no surveillance, including the small supermarket in the village, which deliberately does not have surveillance installed.

The crime scene is on the road between the village primary school and the small supermarket.

Half of this road is a county road and the other half is a village road. The village road is only a little over 3 meters wide and was only repaired in the past 10 years. The county road is a normal asphalt road that can accommodate two cars in parallel, and it looks a little dilapidated.

There is no surveillance within two kilometers of Jide Village, but if you look at the map, the criminal's gray van must pass through the county road to reach Jide Village, and must pass through the vehicle checkpoint several kilometers away.

Now it has not passed, so Jiang Yuan uses LV3 technical defense monitoring technology and LV6 "Image Detection-Trajectory Analysis" to analyze the scene and know that the guy must have found other small roads and bypassed the checkpoint.

There are many possibilities here.

One possibility is that the criminal is very smart, determined the location of the checkpoint, and found ways to bypass the checkpoint without leaving any trace.

Another possibility is that the criminal was lucky and bypassed the checkpoint for some reason.

In addition, it may be relying on locals or gang members familiar with the local area, or it may be time factors, entering and leaving late - the local surveillance is old, and the video resolution at night is extremely low, and the effect is very poor.

"Zhiyang, Yaowei, each of you drives a car and find a way to bypass the two surveillance cameras here and see if there are any routes to take, one to the west and the other to the south."

Jiang Yuan pointed to Mu Zhiyang and Shen Yaowei, and asked each car to take an extra police officer to take photos to see how difficult the bypass route is.

The so-called Skynet is also denser the closer to the central city, and sparser the further it spreads out.

As fixed surveillance points, it is unrealistic to expect them to form a tight and insurmountable large network. It is mainly aimed at people who are not familiar with this system.

In short, Skynet also plays with information gaps.

If a person wants to avoid Skynet's surveillance, there are many ways and means. However, it is difficult to avoid daily activities, and deliberately avoiding will deform the movements, which is the biggest deterrent of the whole system to professional criminals.

Of course, there are always ways, especially for organized crime, the strategies that can be used are also difficult, but the police's means are not limited to surveillance.

Shen Yaowei and Mu Zhiyang returned one after another in less than half an hour.

"There are small roads, which are easy to bypass." After getting off the car, Shen Yaowei began to draw on paper and said, "There are at least two or three small roads that can pass the car. The checkpoint is a crossroads. The village in front is not only populated by people, but also has big car businesses and farmhouses. The road is easy to walk on and you can bypass it without much effort."

Mu Zhiyang waited for him to finish, then stepped forward and said, "I took the west side, which is also easy to bypass. However, I only found one road, which is an old road and difficult to walk on. I have to drive slowly."

"In other words, bypassing itself does not require locals. As long as you know the location of the surveillance, you can easily avoid it." Shen Yaowei summed up, and he understood what Jiang Yuan wanted.

Jiang Yuan only nodded slightly and asked, "How can you know the location of the surveillance?"

"Resources bought on the dark web?" Shen Yaowei is still very trendy.

Jiang Yuan did not comment: "It's possible."

Mu Zhiyang said at this time: "It's safer to take the bad road all the way. The bad road I took should be quite long. Anyway, just walk, there is no way there will be surveillance."

"It's not good if the road is too bad." Shen Yaowei said.

Mu Zhiyang: "The county road we took here is also quite bad in many places in the middle."

"Whether it's a bad road or not, if you want to avoid surveillance, you have to take at least a bad road." Jiang Yuan turned to Wang Chuanxing and said: "Communicate with several captains in the group, and it can also be used as a factor in investigation and inquiry."
