Chapter 30 Wei team can handle
Jiang Yuan first recorded the several cases that Wei Zhenguo mentioned on paper, and then searched for them one by one on the computer.

As Wei Zhenguo said, of the three cases in total, one involved forest land, which was serious arson, but no fingerprints were recorded.Although the fingerprints of the other two were recorded, one burned a tractor that was about to be scrapped, and the other burned an old house that no one lived in.

The fingerprints found by the latter two at the scene are very stretchy, not to mention incomplete, and deformed.

Jiang Yuan reckoned that the policemen from the local police station who did the on-site investigation at that time did not consider the problem of fingerprints going too far, so they just used powder and tape to stick it...

The fingerprints were sent to the trace inspection of the Criminal Division Brigade, not to mention whether they were taken seriously, but based on Jiang Yuan's accurate judgment of the strength of Lao Yan and others, they couldn't handle such fingerprints.

Of course, there is nothing to blame for this.Just like most ordinary people can't get into key universities, key middle schools, or key primary schools, their parents are not industry leaders, their families are not famous, they can't become elites in their fields, and they don't have the luck to lie down and hang out. ...

The county bureau's requirements for technical police officers must not be at the level of TV dramas.

Fingerprints that do not reach the level of major cases are not valued by experts.

Cases with a value of only a few thousand yuan can only be dealt with conventionally.

However, it would be different if these three cases were involved in the arson case in front of the greenhouse.

"Sit down." Jiang Yuan returned to the office.Wei Zhenguo also followed.

As a criminal policeman, he is also a very busy person, but he still wants to see Jiang Yuan's level - trace inspection is the most familiar technical part of ordinary policemen, and he can basically check the fingerprints on the fingerprint card every day. do it.

Jiang Yuan sat up straight, ready to take a good look at these fingerprints.

He first downloaded the fingerprints of the tractor burning case, then stared at the image, lost in thought.

When this fingerprint caught his eyes, Jiang Yuan felt familiar.

Jiang Yuan made the fingerprints of the greenhouse arson case over and over again for a week. Now when he saw the newly downloaded fingerprints, a picture appeared in his mind.

The pictures are not the same, but there is a certain degree of similarity. Considering factors such as the deformation of the fingerprints and the sun exposure, Wei Zhenguo said earlier, it is really possible.

Both have their own flaws. It may be difficult to prove that they are the same fingerprint. Merging two fingerprints into one fingerprint is also a very difficult operation.

However, compared with the Wenxiang arson case, in the tractor burning case, three fingerprints were collected at the fire site, and the completeness is stronger than that of the Wenxiang case.

Jiang Yuan shook his head, rubbed his fingers again, picked up the mouse, and skillfully dragged the fingerprint into Photoshop.

Color scale, adjust contrast, filter background...

Jiang Yuan is doing these things now, like killing fish for selling fish, shelling for selling abalone, and stripping for laughing, which is dizzying.

Wei Zhenguo has also seen trace inspectors do fingerprint matching before. The difficult and hesitant actions make people think that the fish seller is selling abalone, the abalone seller is selling laughter, and the laughing seller is killing fish...

"This fingerprint is promising." Jiang Yuan quickly marked 10 feature points, and then threw them for automatic matching.

A row of 20 fingerprints was released, Jiang Yuan only looked at a few, and then stopped.

He put the two fingerprints on the same screen, made a gesture of tilting his hand to the left, and said slowly: "There is a problem with the direction, but basically the same can be identified."

"Hey, did you win the competition?" Xiao Wang jumped over to look at it first.

"This case of burning the tractor should have won the competition." Jiang Yuan took another look, and his heart felt much better in an instant.

The fingerprints of the greenhouse arson case were compared for a long time, but they failed to match. Jiang Yuan once thought that the corresponding fingerprints were not included in the fingerprint database.

But today's case tore through layers of veil in an instant.

Compared to the case of burning tractors, it is possible to solve a series of cases.

Wei Zhenguo let out a "hiss", and leaned over to look at it, muttering, "So fast..."

He wanted to come over to see how Jiang Yuan made his fingerprints, but he didn't expect that in just a short while, he could see that Jiang Yuan had directly compared his fingerprints—he also found the relevant fingerprints from someone familiar with Qinghe City. I have seen the trace inspection, but it is obvious that the trace inspection in the city is at least not easy to compare fingerprints of this level.

"Do you have any previous convictions for arson?" Wu Jun was also a little curious, wanting to see if the case was really committed by the same person as Wei Zhenguo said.

Jiang Yuan clicked on the detailed information, but shook his head and said, "No. It was the fingerprint collected by the local police station when reporting the loss of his ID card. Later, he was caught stealing with this fingerprint..."

Each police station has a task of collecting fingerprints, which is also a specific item reflected in the "combat power ranking list" of the police station and the county bureau.When necessary, no matter what business you are here for, I will ask you to collect fingerprints first.

Wei Zhenguo nodded lightly, took out his mobile phone, and sent a message while saying, "I'm going to meet this...Jiang Forensic Doctor, thank you for your hard work."

He is an old criminal police officer. Say hello to the captain of the team, and he can go into battle with two people.

While speaking, Wei Zhenguo had already walked to the door, waved his hand, and went out quickly.

Wang Zhong watched Wei Zhenguo leave, his expression suddenly became serious: "Jiang Yuan, Team Wei seems to like you quite a bit."

Jiang Yuan: "How can you tell?"

"Wei team blows beard and stares at other people."

"in this way……"

"Wei team can deal with this person." Wang Zhong sighed and said, "Jiang Yuan, you should seize the opportunity."

"What's the point?" Jiang Yuan looked at Wang Zhong in confusion.

Wang Zhong sighed deeply again: "Captain Wei...Captain Wei's daughter is so pretty."
