Chapter 1020 Elements
Checking hotels, guest houses and homestays in six cities and multiple counties at once can be said to be a very large-scale investigation, but for Xu Taining, it is probably just a drop in the bucket.
Xu Taining already had work to do, and it was impossible for him to come here for such a small investigation - if he came, he would definitely be in charge of the overall investigation. There was really no need for Xu Taining just to check the suspect's accommodation.
Jiang Yuan divided the task among the criminal police teams of the six cities and counties. Involving two provinces and multiple cities, it was indeed difficult to coordinate the actions. Asking the provincial department to come forward could only help with communication, and a higher-level unit would be needed to coordinate the leadership.
At this time, it depends on the capabilities of the criminal police teams themselves.
To be honest, it is not reliable to expect six criminal police teams to be reliable. An organization is more complicated than a person. From a simple perspective, people have headaches and fevers, and organizations also have their periods of change. As for more complicated states, they will affect work efficiency.
So, why is it that Xu Taining's proposal always makes leaders donate generously? Even the most stingy leaders often can't help but be tempted when they hear Xu Taining's proposal.
For example, the current six-county plan does not actually require all six criminal police teams to be reliable.
If we follow Xu Taining's direction to investigate, we may end up with nothing - we are going in the wrong direction, and the criminal did not park the car in the nearest city or county, but always returned to a fixed lair, or he drove to the crime scene all night and did not arrive in advance, and ran away after snatching the child, or he simply slept in the car, and so on, and we may not be able to find him.
Otherwise, the human traffickers are not so frugal, in which case they would not just stay in one place, but would settle down in every place in advance, scout the area, and then carry out the task of stealing and snatching children, and then leave after the robbery.
The probability of the latter is obviously greater. Moreover, if this is the model, even if the criminal police teams in one or two places are not reliable enough, the criminal police teams in other places will provide answers.
In terms of fault tolerance, Xu Taining's plan has already reached the maximum. The cost of each item is actually not high.
The biggest expense for similar investigations is travel expenses. Because police officers do not receive overtime pay, in units with less money, criminal police officers have to pay for their own meals when they work overtime, while in units with more money, they are considered rich if they are provided with a meal and an extra bottle of salty soda.
Therefore, in summary, the investigation plan that Xu Taining came up with in a short time turned out to be the most reliable investigative direction in the entire case. Of course, it is also the most expensive of all the investigative directions currently.
But Jiang Yuan believed that if Director Xu were to take action personally, he would definitely be able to come up with a more expensive and better plan.
……
Jiang Yuan himself did not go with them to check the hotel. Whether it was done by criminal police or assisted by the public security brigade, or by the police station, this job was very tedious and did not require the skills of the criminal department. It was a traditional skill of the iron-footed people.
The other investigation directions are actually similar, including special intelligence, network security, or criminals with criminal records, etc., and Jiang Yuan is not needed.
Jiang Yuan chose to visit the crime scene in the nearest Qingshi City.
Although it was an outdated crime scene and there were no traces of blood or DNA, the first scene was always important. Moreover, without any modesty, Jiang Yuan's crime scene investigation ability was indeed at the top level in the country.
Another thing is that Jiang Yuan was also confused about why the surveillance camera failed to capture any useful information.
Today's Skynet can be said to be very mature. It cannot be said to be without omissions, but there are definitely many loopholes. After all, it is a government project.
However, generally speaking, the best efforts of criminals cannot cover up the deliberate stupidity of administrative personnel. This is the advanced experience of Chinese social governance since Emperor Taizong of Tang.
It is difficult to completely avoid surveillance, even if you have checked the route in advance. The point is, for a human trafficking gang that relies on stealing children to make money, they avoided surveillance six times in a row. Isn't 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 only took twenty minutes to leave Qingshi City, and forty to fifty minutes to enter Cuigang County, but it took a full hour to drive the thirty or forty kilometers from Cuigang County to Lanhua Township.
The crime scene was in Jide Village, south of Lanhua Township. Locally, it was a large village with a village primary school, a small supermarket and a sports field, and more than 200 elderly people and children living there. People from nearby villages also came to Jide Village's village primary school to study and buy things.
However, the village itself does not have any surveillance systems, including the small supermarket in the village, which deliberately does not have any surveillance systems installed.
The crime scene was 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, while the county road is a normal asphalt road that can accommodate two cars in parallel and looks a bit 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 also pass the vehicle checkpoint several kilometers away.
Now that he hasn't passed by, Jiang Yuan used the LV3 technical defense monitoring technology and the LV6 "Image Reconnaissance - Trajectory Analysis" to analyze the scene and found that the guy must have found other paths and bypassed the checkpoint.
There are many possibilities here.
One possibility is that the criminal was very smart and determined the location of the checkpoint, and found ways to bypass it without leaving any traces.
Another possibility is that the criminal was lucky and bypassed the checkpoint for some reason.
In addition, they may rely on locals or gang members who are familiar with the local area, or it may be due to time factors, entering and leaving late - the local surveillance is old, 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. See if there is any route you can take. One of you goes west and the other goes south."
Jiang Yuan selected Mu Zhiyang and Shen Yaowei, and asked each car to have an extra police officer take photos to see how difficult the detour route was.
The so-called Skynet is denser the closer to the central city, and becomes sparser the further outward it spreads.
As fixed monitoring points, it is unrealistic to expect them to form a tight and impenetrable network. They are mainly aimed at people who are not familiar with this system.
In short, Skynet also plays on information asymmetry.
If a person wants to avoid Skynet's surveillance, there are many ways and means. However, it is difficult to avoid it in daily activities, and deliberately avoiding it will distort the movements. This is the biggest deterrent of the whole system to professional criminals.
Of course, there are always ways, especially for organized crime, the strategies they can use are also difficult, but the police have more means than just surveillance.
It took Shen Yaowei and Mu Zhiyang less than half an hour to return.
"There are small roads that are easy to get around." 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 be used by cars. The checkpoint is a crossroads. The village in front is not only crowded with people, but also has big car businesses and farmhouses. The road is easy to use and we can get around it without much effort."
Mu Zhiyang waited for him to finish, then stepped forward and said, "I'll go west, so it's easier to get around. However, I only found one road, an old road, which is not easy to drive on. I have to drive slowly."
"In other words, detouring itself does not require locals. As long as you know the location of the surveillance, you can easily avoid it." Shen Yaowei summed up, knowing exactly what Jiang Yuan wanted.
Jiang Yuan just nodded slightly and asked, "Then how can we know the surveillance location?"
"Resources purchased 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 roads the whole way. The bad road I took should be quite long. Anyway, I'll just walk on it. There's no way there will be surveillance."
"It's not okay if the road is too bad." Shen Yaowei said.
Mu Zhiyang: "The county road we took here was pretty bad in many places."
"Whether you take the bad road all the way or not, if you want to avoid surveillance, you have to take at least a section of the bad road." Jiang Yuan turned to Wang Chuanxing and said, "Communicate with a few captains in the group, which can also be used as a factor in troubleshooting and questioning."
