Chapter 1003: Elements

Screening inns and hotels, plus homestays, etc., in 6 cities and multiple counties in one go can be said to be a very huge screening, but to Xu Taining, it's probably just a splash of water.

Xu Taining himself has work to do, and it's impossible for him to run over for such a small screening job—if he were to come, he would definitely have to preside over the overall screening work. Just screening the suspect's accommodation location really doesn't need Xu Taining.

Jiang Yuan broke down the task to the criminal police teams of the six cities and counties to do themselves. Involving two provinces and multiple cities, the difficulty of unified action is indeed a bit high. Asking the provincial department to come forward can only communicate, but unified leadership requires the appearance of higher-level units.

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

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

So, why is it said that Xu Taining's plan always makes leaders generous? Even the stingiest leader, upon hearing Xu Taining's plan, often can't help but be moved.

Like the six-county plan this time, it actually doesn't require all six criminal police teams to be very reliable.

According to Xu Taining's direction to screen, either it will be a walk in the air—the direction is wrong, and the criminal didn't park the car in the nearest county or city at all. Maybe they return to a fixed nest every time, or drive all night to the crime scene without arriving in advance, snatch the child and run, or just sleep in the car, etc., all of which might not be screened.

Or, the human traffickers aren't that hard-working and simple. Then they won't just stay in one place, but will stay in advance in each place, step on the spot, and then execute the work of abducting children, and leave after snatching.

The probability of the latter is obviously higher. Moreover, if it's this mode, even if one or two places' criminal police teams aren't reliable enough, other places' criminal police teams will give answers.

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

For similar screening, the biggest expense is travel expenses. Because police officers have no overtime pay, in units with less money, the meals criminal police officers eat when working overtime are bought with their own money. In units with more money, providing a meal and giving an extra bottle of salt soda water is considered a wealthy clan.

Therefore, comprehensively, the screening plan that Xu Taining thought of in a very short time turned out to be the most reliable investigation direction in the entire case. Of course, it is also the most expensive one among all current investigation directions.

But Jiang Yuan believes that if Division Chief Xu were to go out himself, he would definitely have more expensive and better plans to propose.

Jiang Yuan himself didn't follow to screen hotels. This work, whether done by criminal police or asking the public security detachment to assist, or asking the police station for help, is very cumbersome and doesn't need criminal science technology. It belongs to the traditional skills of the iron-footed ones.

Other investigation directions are actually about the same, including special intelligence, cyber security, or former criminal routes, etc., none of which need Jiang Yuan.

Jiang Yuan chose to go see the crime scene in Qingshi City, which was the closest.

Although it was an outdated crime scene and there were no traces like blood or DNA, the first crime scene is always important. Moreover, without being modest, Jiang Yuan's crime scene investigation ability is also truly at the top level in the country.

Another thing, Jiang Yuan was also suspicious that surveillance didn't capture any useful information.

The current Sky Net can be said to be very mature. It can't be said there are no omissions; the loopholes are definitely very many, after all, it is a government project.

However, usually, the wisdom of criminals trying their best still cannot cover the deliberate stupidity of administrative personnel. This is an advanced experience of Chinese social governance since Emperor Taizong of Tang.

Completely avoiding surveillance, even if they stepped on the spot in advance and checked the route, is quite difficult. The key is, a human trafficking gang relying on abducting children to make money, continuously avoiding surveillance six times—is this execution ability a bit too strong?

Jiang Yuan sat in the car for over two hours before arriving at Lanhuaxiang, Cuigang County, Qingshi City.

Leaving Qingshi City only took twenty minutes, and entering Cuigang County was only forty or fifty minutes, but the thirty or forty kilometers from Cuigang County to Lanhuaxiang took a full hour.

The crime scene is in Jide Village, south of Lanhuaxiang. Locally, this is a large village, with a village primary school, a small village supermarket and sports field, and more than two hundred elderly people and children living here. Nearby small villages also have people coming to Jide Village's primary school to study and buy things.

But the village itself has no surveillance, including the small supermarket in the village, which also deliberately has no surveillance installed.

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

This road is half county road and half village road. The village road is only a little over 3 meters wide and was built in the last 10 years. The county road is a normal asphalt road that can accommodate two cars side-by-side, looking slightly old and in disrepair.

And within two kilometers near Jide Village, there is also no surveillance. But if you look at the map, the criminal's gray van to reach Jide Village must pass through the county road and must pass through the vehicle checkpoint a few kilometers away.

Now that it didn't pass, Jiang Yuan used LV3 technical defense surveillance technology and LV6 "Image Investigation—Trajectory Analysis." On-site analysis shows that it must have found other small roads to bypass the checkpoint.

There are many possibilities here.

One possibility is that the criminal is very smart, determined the location of the checkpoint, and tried every means to bypass the checkpoint without leaving traces.

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

In addition, it may also rely on locals or gang members familiar with the area, or it may be a time factor—late entry and late exit—the local surveillance is old, the video resolution at night is extremely low, and the effect is very poor.

"Zhiyang, Yaowei, you two drive one car each, find a way to bypass the two surveillance cameras here, see what routes you can take, one goes west, one goes south."

Jiang Yuan picked Mu Zhiyang and Shen Yaowei, and let each car take an extra police officer to take photos, to see how difficult the bypassed routes are.

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

As a fixed surveillance point, expecting them to form a tight, impassable large net is unrealistic. It mainly targets people who are unfamiliar with this set of systems.

In short, Sky Net also plays on information gaps.

If a person wants to avoid Sky Net surveillance, there are many ways and means. However, daily activities are very difficult to avoid, and deliberate avoidance will make the actions deformed. This 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 just surveillance.

Shen Yaowei and Mu Zhiyang took less than half an hour to return one after another.

"There are small roads, very easy to bypass." After Shen Yaowei got out of the car, he consciously started drawing on paper and said: "There are at least two or three small roads that can pass cars. The checkpoint is a crossroads. The village nearby not only has many people living there, but also people doing big car business and people opening farmhouse restaurants. The road is very easy to walk, and you can bypass it without much effort."

Mu Zhiyang waited for him to finish and then stepped forward: "I walked west, and it was also easy to bypass. However, I only found one road, which is an old road, not easy to walk, have to drive slowly."

"In other words, bypassing itself doesn't need locals. As long as you know the location of the surveillance, you can easily avoid it." Shen Yaowei summarized, very understanding of what Jiang Yuan wanted.

Jiang Yuan just nodded slightly and asked: "Then how can you know the surveillance location?"

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

Jiang Yuan didn't commit: "It's possible."

Mu Zhiyang said at this time: "It's safer to walk the rotten road the whole way. The broken road I walked should be quite long. Anyway, just walk it. There's no way there could be surveillance."

"The road is too rotten, it won't work, right?" Shen Yaowei said.

Mu Zhiyang: "The county road we walked over, many places in the middle were also quite rotten."

"Regardless of whether you walk the rotten road the whole way, if you want to avoid surveillance, you have to walk a section of the rotten road at least." Jiang Yuan turned to Wang Chuanxing: "Communicate with several detachment captains in the group, it can also be used as an element of screening inquiry." ===== CHAPTER 1004 =====
