Chapter 30 Captain Wei Can Handle

Jiang Yuan first recorded the cases mentioned by Wei Zhenguo on paper, and then searched for them one by one in the computer.

As Wei Zhenguo said, there were a total of 3 cases. One involved forest land, which was a serious arson, but no fingerprints were recorded. Although fingerprints were recorded in the other two, one burned a tractor that was about to be scrapped, and the other burned an old house that was uninhabited.

The fingerprints found at the scene of the latter two were very poor, not to mention incomplete, and deformed.

Jiang Yuan estimated that the police who conducted the on-site investigation at the time might be the police from the local police station, and they did not consider the problem of fingerprints being burned, so they just used powder and tape to stick them...

The fingerprints were sent to the trace inspection of the Criminal Science Brigade. Regardless of whether they were taken seriously, Jiang Yuan's accurate judgment of the strength of Lao Yan and others showed that they could not handle such fingerprints.

Of course, there was nothing to blame. Just like most ordinary people cannot get into key universities, key middle schools, or key primary schools, their parents are not industry leaders, their families are not famous, they cannot become elites in their fields, and they do not have the luck to cheat...

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

Fingerprints that do not reach the level of major cases will not be taken seriously by experts and bosses.

Cases with a case value of only a few thousand yuan can only get conventional solutions.

However, if these three cases can be related to the previous greenhouse arson case, it will be different.

"Please sit down." Jiang Yuan returned to the office. Wei Zhenguo also came over.

As a criminal policeman, he is also a busy man, but he still wants to see Jiang Yuan's level - trace inspection is the most familiar technical part of ordinary police officers. He can basically do daily verification of fingerprints on fingerprint cards.

Jiang Yuan sat up straight and prepared to take a good look at these fingerprints.

He first downloaded the fingerprints of the case of burning tractors, and then looked at the image and fell into deep thought.

This fingerprint made Jiang Yuan feel familiar.

Jiang Yuan had been working on the fingerprint of the greenhouse arson case for a week. Now, when he looked at the newly downloaded fingerprint, the picture appeared in his mind.

The picture was not quite the same, but there was a certain degree of similarity. Considering the deformation of fingerprints and factors such as fire and sun exposure, what Wei Zhenguo said before was really possible.

Both of them were incomplete, and it might be difficult to prove that they were the same fingerprint. It was also very difficult to merge two fingerprints into one.

However, compared with the Wenxiang arson case, the case of burning tractors collected 3 fingerprints at the fire point, and the completeness was better than that of the Wenxiang case.

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

Adjust the color level, adjust the contrast, filter the background...

Jiang Yuan now does these things smoothly, like a fishmonger killing fish, an abalone seller peeling shells, and a smiler stripping clothes, which is dazzling.

Wei Zhenguo had also seen the trace examiners doing fingerprint matching before. The difficult and hesitant movements could easily make people think that the fish seller was selling abalone, the abalone seller was selling smiles, and the smiler was killing fish...

"This fingerprint has hope." Jiang Yuan quickly marked 10 feature points and sent it to automatic matching.

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

He put the two fingerprints on the same screen, tilted his hand to the left, and said slowly: "The direction is a bit problematic, but it can basically be identified as the same."

"Huh, did it match?" Xiao Wang jumped over to see first.

"This case of burning tractors should have matched." Jiang Yuan took another look, and his heart was instantly relieved.

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

But today's case instantly tore through the layers of veils in the middle.

The case that was matched was the case of burning tractors, but the case that was solved might be a series of cases.

Wei Zhenguo let out a "hiss" and came over to see, muttering: "So fast..."

He wanted to come and see how Jiang Yuan did the fingerprints, but he didn't expect that in just a short while, he could see Jiang Yuan directly match the fingerprints - he also looked at the relevant fingerprints with the familiar trace inspection in Qinghe City, but it was obvious that it was at least not easy for the trace inspection in the city to match fingerprints of this level.

"Does he have a criminal record of arson?" Wu Jun was also a little curious and wanted to see if this 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. The local police station collected his fingerprints when he reported the loss of his ID card. Later, he used this fingerprint to catch him stealing..."

Every police station has the task of collecting fingerprints, which is also reflected in the specific items in the "combat power ranking list" of police stations and county bureaus. When needed, no matter what business you come here for, we will collect your fingerprints first.

Wei Zhenguo nodded slightly, took out his mobile phone, and sent a message while saying: "I'll go meet this... Forensic Doctor Jiang, thank you for your hard work."

He is an old criminal policeman. He just said hello to the captain of his team and took two people with him.

As he spoke, Wei Zhenguo had walked to the door, waved his hand, and went out quickly.

Wang Zhong watched Wei Zhenguo leave, and his expression suddenly became deep: "Jiang Yuan, Captain Wei seems to like you very much."

Jiang Yuan: "How did you see that?"

"Captain Wei is always glaring at other people."

"This is like..."

"Captain Wei is someone you can get along with." 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 beautiful."
