Chapter 349 Searching for Old Cases
Searching for old cases was something Jiang Yuan had done before.

Of course, there is no need to seek novelty or strangeness when doing a case. As long as it can solve the case, it is a good trick. Who cares whether it has been used before.

In fact, when normal police officers handle cases, they only use the tricks they have used before.Otherwise, if you use new, strange and weird tricks on important cases, it will be cool if you succeed, but what about failure?The leaders of the criminal police swear, some are really cruel, dirty and cruel.

Jiang Yuan's own skills are updated quickly, and his subordinates don't have such conditions.

For example, Wang Chuanxing and others, even when searching for old cases, were trembling, for fear that they would make mistakes or make mistakes, which would lead to problems in this case listed and supervised by the ministry.

However, the first half of the night passed, and by the second half of the night, Wang Chuanxing and others became peaceful.In other words, the chemical element of worry is used up, leaving numbness and persistence.

Jiang Yuan is also a case-by-case fool.

When doing criminal cases, the most tiring thing is the hands and eyes. You have to run endless roads, write endless reports, and read endless files.

Most of the cases can be handled step by step, making the criminal police look a bit like a company salesman, running around the business every day, and writing about things.

The very few cases, the cases that really need to use the brain, are very painful.

For example, in the current case, it is still very difficult to find a similar child abduction case.

What is the simplest, similar standard?
In fact, no one can give this definition.Because criminals are different, investigators can only guess by themselves if they are not familiar with the criminal.

Those who also trafficked children in the vegetable market must be A-level similar.Too bad there is no such case.

Those who kidnap and traffic children in very lively places and use non-violent means are about C grade.It is a pity that the few cases found are obviously different.

Abducting and trafficking multiple children in a short period of time should be considered a B-level case, but unfortunately no similar cases have been found.

"There are no more cases." By the time the sun was dim in the morning, the last file had been read.

Gao Changjiang was also a little disappointed, and sighed: "It seems that this road is not going to work."

"Look for a few more provincial dossiers." Jiang Yuan has no intention of giving up.

Gao Changjiang frowned and said, "Is it necessary?"

"If you have other plans, you can also do it. I will lead people to search for old cases." Jiang Yuan's self-confidence comes from his comprehensive skills.In the case of Guqi City, he has seen all the clues that can be found, whether it is fingerprints, traces or images, basically he can't break through.

Considering that Jiang Yuan has mastered so many skills, and has multiple LV3, LV4 and even LV6 skills, it is very unwise to continue to study the clues of this case.

From Jiang Yuan's own point of view, he thinks it's a smarter way to find an old case, not a stupid way.

In other words, in the absence of a smarter approach, at least the stupid way may work.

Gao Changjiang does not have Jiang Yuan's technical ability, and he still has expectations for experts in his heart-of course, experts in different fields may have other breakthrough methods, but this is beyond Jiang Yuan's range.

With Jiang Yuan's ability and skill range, he thought he had chosen the most appropriate way, and he was still far away from hitting the south wall.

Seeing this, Gao Changjiang could not force Jiang Yuan to command.Look at him bringing 8 people, just think he is a habitual self-made type.

Thinking about it this way, Gao Changjiang respected Jiang Yuan a little more. After all, he was an experienced team anyway.

"That's fine, you read the file yourself, what we say..." Gao Changjiang looked at the other experts.

"If it really doesn't work, let's scan the video during the incident again." The suggestion made by the video expert is naturally video.

"You can decompose the footprints. Track the gait, but it's too messy..." The footprint experts also suggested the footprints.

Jiang Yuan looked at it and said nothing. To be honest, he knew a little about images and footprints. Judging from the photos and the situation on the scene, he thought it was useless.

The criminal chose the simplest and most effective way, which is to leave traces to the children and the environment, then find an environment that is not easy to trace, and take the children away.

Such a mature criminal path requires not only rich experience, but also adaptation to the environment, and a certain degree of proficiency.That's why Jiang Yuan put the time and place of reading the case file in the surrounding provinces and within two years.

As far as Jiang Yuan's current experience is concerned, these two judgments are not bad.

Jiang Yuan rubbed his head, went back to his room and continued to read the files.

This time, it didn't take too long to watch.

An old case in a neighboring province caught Jiang Yuan's attention.

The place where the case happened is Daji in the countryside, which is somewhat similar in nature to the vegetable market, but it doesn't explain much of the problem. The key lies in the way the children were taken away. The traffickers first found the children who had escaped the control of their parents, and then claimed to take them to their mothers. .

As soon as the child heard that he was looking for his mother, he followed him.Then, one in front and the other in the back walked out, without even hugging and coaxing.

However, this time, the child who was coaxed was a little older. The six-year-old child called his mother while walking, which attracted the attention of the surrounding people.But the kidnapper still ran away decisively.

Jiang Yuan couldn't help recalling the four cases in Guqi City.Children out of control and out of sight were mentioned in two cases and not in the other two.

Jiang Yuan immediately found Gao Changjiang and said, "Call the victim's family and ask if they have something to hide."

"You want them to admit that the child was first out of control and then lost? This is a bit difficult." Gao Changjiang found it difficult when he heard Jiang Yuan's request.

Jiang Yuandao: "This is the key factor that affects whether the case can be merged. Moreover, it is not out of control in the sense of the criminal law. If you are not leading, if you leave your sight for a few seconds or more than ten seconds, it is considered out of control."

Gao Changjiang thought about it, and couldn't help but sigh: "All right, I'll ask."

It has to be said that the things Jiang Yuan took out were very fancy. Gao Changjiang stared at the scolding, and also called the two victims separately, and got the results smoothly.

"It's really out of sight." Gao Changjiang finished the phone call, turned around, and asked a little strangely: "Is this equivalent to human traffickers picking up children?"

"It's also the one that is the easiest to attack." Jiang Yuan paused, and then said: "In this case, we can break the old case first."

If you can't solve the new case, you will search the old case. This is a normal way of thinking.

The key is to find the old case and establish a connection with the new case.

At this time, Gao Changjiang was a little aware of Jiang Yuan's toughness, and he didn't say a word, so he followed Jiang Yuan's actions.
