Chapter 348 Searching for Old Cases

, the latest chapter is updated the fastest!

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

Of course, solving cases is not about seeking new or strange things. As long as it can solve the case, it is a good trick. Who cares whether it has been used before?

In fact, normal policemen will only use the tricks they have used before to solve cases. Otherwise, if you use new, strange and weird tricks on big cases, it will be very handsome if you succeed, but what if you fail? The leaders of criminal police scold people, some of them are really cruel, dirty and cruel.

Jiang Yuan's own skills are updated quickly, and he does not have such conditions under his hands.

For example, Wang Chuanxing and others, even when searching for old cases, are trembling, for fear that they will make mistakes and miss things, which will cause problems in this case supervised by the ministry.

However, after spending the first half of the night, Wang Chuanxing and others calmed down in the second half of the night. Or, the chemical element of worry has been used up, leaving only numbness and persistence.

Jiang Yuan was also a fool looking at each case.

The most tiring part of criminal investigation is the hands and eyes, which means running endless roads, writing endless reports, and reading endless files.

Most cases can be handled step by step, making criminal police become a bit like company sales, running business and writing things every day.

The very few cases that really require the use of brains are very painful.

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

The simplest thing is, what is the standard of similarity?

In fact, no one can give this definition. Because criminals are different, if they are not familiar with the case, the investigators can only guess by themselves.

Those who also trafficked children in the vegetable market must be similar to Class A. Unfortunately, there is no similar case.

Those who also trafficked children in a very busy place and used non-violent means are probably Class C. Unfortunately, the few cases found are obviously different.

Trafficking multiple children in a short period of time and for many days should be considered Class B, but unfortunately, no similar cases have been found.

"There are no more eucalyptus." When the morning sun was just beginning to shine, the last file was also finished.

Gao Changjiang was also somewhat disappointed, and sighed: "It seems that this road is not feasible."

"Find more files from a few provinces to see." Jiang Yuan did not mean to give up.

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

"You can do other plans, I will take people to search for old eucalyptus." Jiang Yuan's confidence comes from his comprehensive skills. He has seen all the clues that can be found in the eucalyptus in Guqi City. Whether it is fingerprints, traces or images, it is basically impossible to break through.

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

From Jiang Yuan's own point of view, he thinks that finding old eucalyptus is a smarter way, not a dumb way.

In other words, in the absence of a smarter way, the dumb way at least has the possibility of working.

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

With Jiang Yuan's ability and skill range, he believes that he has chosen the most appropriate way, and he is still far from hitting the wall.

Seeing this, Gao Changjiang cannot force Jiang Yuan to command. Seeing that he brought 8 people, he just thought that he was habitually self-willed.

Thinking of this, Gao Changjiang has more respect for Jiang Yuan. After all, it is an experienced team.

"Okay, you look at the files yourself, as for us..." Gao Changjiang looked at other experts.

"If it doesn't work, let's scan the images during the incident again." The suggestions made by the imaging expert are naturally about images.

"You can break down the footprints again. Track the gait, but it's too messy..." The footprint expert also made suggestions about footprints.

Jiang Yuan looked at it without saying anything. To be honest, he knows a little about images and footprints. Judging from the photos and the situation at the scene, he thinks there is no hope.

This criminal chose the simplest and most effective way, which was to leave all traces on the children and the environment, and then find an environment that is not easy to track and take the children away.

Such a mature criminal path requires not only the criminals to be experienced, but also to adapt to the environment, and also to have a certain degree of proficiency. Therefore, Jiang Yuan placed the time and place of reading the case files in the surrounding provinces and within two years.

Based on Jiang Yuan's current experience, these two judgments are almost the same.

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

This time, he didn't read it for too long.

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

The location of the case was a rural market, which was somewhat similar to the nature of a vegetable market, but it didn't explain much. The key was the way of taking the children away. The traffickers actually found the children who were out of the control of their parents first, and then claimed to take them to their mothers.

When the children heard that they were going to find their mothers, they followed. Then one walked out in front and the other in the back, without even holding and coaxing.

However, this time, because the child was a little older, the six-year-old child called for his mother while walking, which attracted the attention of the people around him. But the kidnapper still ran away decisively.

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

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

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

Jiang Yuan said, "This is a key factor that affects whether the case can be combined. Moreover, it is not out of control in the sense of criminal law. If the child is not held and out of sight for a few seconds or more than ten seconds, it is considered out of control."

Gao Changjiang thought about it and sighed, "Okay, I'll go ask."

It must be said that what Jiang Yuan took out was still very fancy. Gao Changjiang stared at it and was scolded, and he also called the two victims separately and got the result smoothly.

"They are all out of sight." Gao Changjiang finished the call, turned around, and asked in a strange way: "Is this equivalent to human traffickers picking up children?"

"They are also selecting the easiest ones to attack." Jiang Yuan paused, and then said: "In this case, we can solve the old case first."

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

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

At this time, Gao Changjiang realized Jiang Yuan's strength, and without saying a word, he followed Jiang Yuan's instructions.
