Searching for old cases is something Jiang Yuan had done before.

Of course, when doing a case, you don’t seek new things or strange things. As long as you can solve the case, it is a good trick. Who cares if you have used it before?

In fact, when normal policemen do cases, they only use tricks they have used again. Otherwise, if you use new, strange and strange tricks on major cases, you will be very handsome if you succeed, but what if you fail? The leaders of the criminal police are really cruel, dirty and ruthless.

Jiang Yuan's own skills are updated quickly, so there is no such condition under his command.

For example, Wang Chuanxing and others, even when searching for old cases, they were trembling, fearing that they would do something wrong or omit it, which would lead to problems in this case supervised by ministries and commissions.

However, in the first half of the night, Wang Chuanxing and others became peaceful. In other words, they used up all the chemicals of worry, and only numbness and persistence were left.

Jiang Yuan is also a fool of himself.

When doing criminal cases, the most tiring thing is the scaffolding and eye contact, which means running endless roads, writing endless reports, and reading endless files.

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

A very small number of cases, cases that really require brain-based use will be very painful.

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

What is the simplest, similar standard?

In fact, no one can give this definition. Because criminals are different, when they are not familiar with the criminal, they can only be the investigators themselves to guess.

Those who also abduct children in the vegetable market must be similar to A-level. Unfortunately, there is no same case.

Those who also abduct children in very lively places and use non-violent means are roughly C-level. Unfortunately, the cases found are obviously different.

Those who abducted and sold multiple children in a short period of time should be considered B-level, but unfortunately no similar case was found.

"There is no case." When the sun was shining in the morning, the last file was finished.

Gao Changjiang was also a little disappointed and sighed, "It seems that the road is not open."

"Look for more documents from a few provinces." Jiang Yuan had no intention of giving up.

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

"You can do other solutions, and I will take someone to search for old cases." Jiang Yuan's confidence comes from his comprehensive technology. He has seen all the clues that can be found in Guqi City's case, and no matter whether it is fingerprints, traces or images, it is basically impossible to break through.

Considering that Jiang Yuan has so many skills and multiple LV3, LV4 and even LV6 skills, it would be unwise to continue to fight the clues of this case.

From Jiang Yuan's own point of view, he believes that finding old cases is a smarter way, rather than a stupid way.

In other words, in the absence of a smarter approach, there is at least a possibility of being able to make it happen.

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

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

Seeing this, Gao Changjiang could not force Jiang Yuan. He took 8 people and just thought he was a habitual person and was a good person.

Thinking of this, Gao Changjiang has a little more respect for Jiang Yuan. After all, it can be considered an experienced team after all.

"Okay, you can read the file yourself, if we say it..." Gao Changjiang looked at other experts.

"If it really doesn't work, let's scan the images during the incident again." The suggestions put forward by the imaging expert are naturally based on the images.

"You can break down the footprints and track the gaits, but it's too messy..." The footprint experts also put forward the footprint suggestions.

Jiang Yuan looked at it and said nothing. To be honest, he understood the image and the footprints. Judging from the photos and the situation on the scene, he felt that there was no chance.

The criminal chose the easiest and most effective way, which is to leave all traces to children and the environment, and then find an environment that is difficult to track and take away the children.

Such a mature criminal path requires not only the criminals to be experienced, but also to adapt to the environment and have a certain degree of proficiency. Therefore, Jiang Yuan placed the time and place of 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 very different.

Jiang Yuan rubbed his head and went back to the room to continue reading the file.

This time, I didn't watch it for too long.

An old case from a neighboring province attracted Jiang Yuan's attention.

The case occurred in a rural market, which is somewhat similar to the nature of the vegetable market, but it does not explain much. The key is the way to take the children away. The traffickers actually found the children who were out of their parents' control before claiming to take them to their mothers.

When the child heard that he was going to find his mother, he followed him. Then one in front and the other in the back walked out, without even holding and coaxing him.

However, this time, the six-year-old child was a little older because of his deception. As he walked, he called his mother and attracted the attention of the people around him. But the kidnapped still ran away decisively.

Jiang Yuan couldn't help but recall four cases in Guqi City. Two cases mentioned that children were out of control and sight, while the other two were not mentioned.

Jiang Yuan immediately found Gao Changjiang and said, "Call the victim's family and ask if they have any hidden scenes but have not said it."

"Do you want them to admit that the children were out of control first and then lost? This is a bit difficult." Gao Changjiang felt it difficult when he heard Jiang Yuan's request.

Jiang Yuan said: "This is a key factor affecting whether the case can be merged. Moreover, it is not a criminal law that is out of control. Without being held, it is out of sight for a few seconds or ten seconds, even if it is out of control."

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

I have to say that the things Jiang Yuan took out were still very beautiful. Gao Changjiang stared at him and was scolded, and beaten them to the victims of the two families, and the results were successfully obtained.

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

"It is also the easiest to choose the one that can be used to." Jiang Yuan paused and said, "In this way, you can first tease the old case."

If you can't solve the new case, you can search for the old case. This is a very normal idea.

The key is to find old cases and establish connections with new cases.
