Chapter 345: Propaganda
Old cases are something Jiang Yuan had done before.
Of course, doing cases doesn't seek novelty or strangeness. As long as the case can be solved, they are all good tricks. Who cares if they have been used before?
In fact, normal police doing cases use tricks that have been used before. Otherwise, for new, strange, and weird tricks, if you use them on major cases, it's quite handsome if you succeed, but what if you fail? The leaders of the criminal police scolding people can be really ruthless; it's dirty and ruthless.
Jiang Yuan's own skills update quickly, but he didn't have such conditions under his hands.
Like Wang Chuanxing and others, even when searching for old cases, they were trembling with fear, afraid that they would do something wrong or miss something, leading to problems with this ministry-supervised case.
However, after the first half of the night passed, by the second half of the night, Wang Chuanxing and the others became peaceful. Or rather, the chemical element of worry was used up, and only numbness and persistence remained.
Jiang Yuan was also looking stupidly at one case after another.
Doing criminal cases, the most tiring things are feet, hands, and eyes. It is to run endless roads, write endless reports, and look at endless case files.
Most cases can be done step by step, making criminal police look a bit like company sales, running business and writing things every day.
A very small number of cases, cases that truly need the brain, are very painful.
For example, the current case, it is still very difficult to find a similar child abduction case.
The simplest, what is the standard for similarity?
Actually, no one can give this definition. Because criminals are different, in the case of not being familiar with the perpetrator, one can only guess by the investigation personnel themselves.
Those who abduct children in the vegetable market are definitely A-level similarities. Unfortunately, there is no similar case.
Those who abduct children in very lively places and use non-violent means are about C-level. Unfortunately, the few cases found have obvious differences.
Those who abduct multiple children in multiple days in a short time should be considered B-level. Unfortunately, no similar case was found.
"No more cases." By the time the morning sunlight was slightly bright, the last case file had been read.
Gao Changjiang was also a bit disappointed, sighed, and said: "It seems this road is also impassable."
"Look for case files from a few more provinces." Jiang Yuan did not mean to give up.
Gao Changjiang frowned and said: "Is it necessary?"
"You can do other plans if you have them. I will take people to search for old cases." Jiang Yuan's confidence came from his comprehensive technology. For the case in Guqi City, he had already looked at the clues that could be found. Regardless of fingerprints, traces, or images, basically, there was no breakthrough.
Considering that Jiang Yuan mastered so many skills and had multiple LV3, LV4, and even LV6 skills, it was very unwise to continue to struggle with the clues of this case.
From Jiang Yuan's own point of view, he thought that finding old cases was a smarter approach, not a stupid method.
Or rather, in the absence of a smarter approach, the stupid method at least had the possibility of being passable.
Gao Changjiang did not possess Jiang Yuan's technical ability, and in his heart, he still had expectations for the experts—of course, experts in different fields might have other breakthrough means, but this was also something beyond Jiang Yuan's range.
With Jiang Yuan's ability and skill range, he considered that he had already chosen the most appropriate method, and he was still far from hitting the south wall. Gao Changjiang saw this, and could not forcibly command Jiang Yuan. Looking at him bringing 8 people, he just took it as him being habitually self-acting.
Thinking this way, Gao Changjiang had two more points of respect for Jiang Yuan. After all, no matter what, it could be considered an experienced team.
"Alright, you look at the case files yourself. As for us..." Gao Changjiang looked at other experts.
"If it really doesn't work, let's scan the images during the incident again." The suggestion made by the image expert was naturally about images.
"We can decompose the footprints again. Track the gait, but it's too messy..." The suggestion made by the footprint expert was also about footprints.
Jiang Yuan watched without speaking. To tell the truth, he knew a little about images, and he knew a little about footprints. Looking at the photos and the situation at the scene, he felt that there was no play.
This perpetrator chose the simplest and most effective road, which was to leave the traces to the children and the environment, and then find an environment that was not easy to track, and take the children away.
Such a mature criminal path not only requires the criminal to be experienced, but also requires adaptation to the environment, and also requires a certain proficiency. Therefore, Jiang Yuan placed the time and place of looking at the case files in the surrounding provinces and within two years.
From Jiang Yuan's current experience, these two judgments were about the same.
Jiang Yuan rubbed his head and returned to the room to continue looking at the case files.
This time, it didn't take too long.
An old case in a neighboring province caught Jiang Yuan's attention.
The location where the case occurred was a rural fair, which was somewhat similar to the nature of a vegetable market, but it couldn't explain much. The key was the way the child was taken away. The human trafficker actually found a child who had left the control of his parents, and then claimed to take them to find their mother.
The child followed as soon as he heard it was to find his mother. Then one walked out in front, and one walked out behind, without even needing to be held or coaxed.
However, this time, because the child being coaxed was slightly older, a six-year-old child, he called for his mother while walking, which attracted the attention of the surrounding crowd. But the abductor still decisively fled.
Jiang Yuan couldn't help but recall the four cases in Guqi City. Two cases mentioned that the children left control and sight, and the other two did not mention it.
Jiang Yuan immediately found Gao Changjiang and said: "Call the victim's family and ask if they have any hidden situations that they didn't say."
"You want them to admit that the child left control first and then was lost? This is a bit difficult." Gao Changjiang felt it was difficult as soon as he heard Jiang Yuan's request.
Jiang Yuan said: "This is the key factor affecting whether the cases can be combined. And it is not leaving control in the sense of criminal law. Not holding hands, leaving sight for a few seconds, ten seconds, is leaving control."
Gao Changjiang thought about it and couldn't help but sigh: "Alright, I'll go ask."
It must be said that the things Jiang Yuan brought out were still very interesting. Gao Changjiang stared at being scolded, and also called the two victim families separately, and successfully obtained the results.
"It actually really was leaving sight." Gao Changjiang finished the call, turned back, and asked with some strangeness: "This is equivalent to the human trafficker picking up children?"
"It is also filtering out the easiest to start with." Jiang Yuan paused and added: "In this case, we can solve the old case first."
Not being able to solve the new case, and searching for the old case, is a very normal line of thinking.
The key is also finding the old case and establishing a connection with the new case.
Gao Changjiang realized Jiang Yuan's toughness at this time, and without another word of nonsense, he followed Jiang Yuan's way of doing things.
