Chapter 19 Don’t be too idle

Jiang Yuan took out the first fingerprint. It was only the first half of the fingerprint, and the position was relatively blurry.

Faced with such a fingerprint, the first thing Jiang Yuan had to do was to determine which finger it belonged to.

After that, the fingerprint image is processed.

Finally, the feature points are marked.

After Jiang Yuan obtained the fingerprint skill, he used it a few times, and he felt a little familiar with it. Now he can operate it very smoothly.

The slightly blurry fingerprint image after enlargement was continuously enlarged and shrunk under Jiang Yuan's mouse, changing the color level, brightness and light and dark from time to time. At the same time, Jiang Yuan also continued to mark feature points.

Wang Zhong felt dazzled. After watching it for a while, he couldn't stand it anymore.

PS is a software with quite powerful built-in functions and a large number of shortcut keys to facilitate users to improve efficiency.

But for onlookers, if the person using it does not explain or explain, the onlookers will feel dizzy after pressing the shortcut keys.

Just like Wang Zhong's current state.

"Come on, I'm going back first." Yan Ge said hello and went back to his office to work.

Wu Jun naturally looked at Wang Zhong and said with a smile, "Won't Xiao Wang go back to work?"

"Do it... I'll watch it for a while, study, and then go back and do it." Wang Zhong didn't quite understand Jiang Yuan's operation, but he knew that Jiang Yuan was processing fingerprints now.

In fact, even if Jiang Yuan explained this operation to him in detail, he wouldn't be able to remember it. Even if he remembered it, he wouldn't be able to use it for a while.

Anyway, Wang Zhong just stared blankly, learning as much as he could.

At least, he can learn something now. In the past, when Wang Zhong followed Yan Ge, he had nothing to learn.

During the process of image processing, Jiang Yuan marked 4 feature points. After completing this step, he chose a direction from another corner, marked 5 feature points, and said: "Let's take a look at these first."

Wang Zhong felt dazed. Before he entered the state, he saw that Jiang Yuan had already made the software run.

After a while, 20 fingerprints appeared on the candidate list.

Jiang Yuan eliminated them one by one and marked them again.

Wang Zhong soon became tired of watching.

For fingerprint inspection, comparing fingerprints is extremely boring.

This process is like a person trying to find a twin for a hedgehog.

He can first pull out 8 thorns and compare them all over the world. If he fails, he can pull out a few more thorns, or mix them with some of the previous 8 thorns, or form an independent team and continue the comparison all over the world. Until the match is successful, check again whether all the thorns are the same.

There is an old saying: 8 roots after 8 roots, 8 roots after 8 roots, the roots are different, hard and slender.

Jiang Yuan took the trouble to compare for half an afternoon, and when it was time to get off work, he finally announced that the comparison of the first fingerprint had failed.

"Go home." Jiang Yuan packed his bags and prepared to get off work on time.

Wang Zhong is like a physics enthusiast who feels dazed and sleepy after listening to a lecture on theoretical physics for half an afternoon - he feels that he should like and be excited, but his body and brain think he is wrong, so that he Now I have doubts about my own existence.

Jiang Yuan didn't care so much. He went home to eat meat and shared his reward with his father.

"I won an award just after I started working. It's not bad." Jiang Fuzhen looked happy. He took out his mobile phone and called Aunt Hua, saying, "Do you know how much money young people earn now? More than 10,000 yuan." not much?"

"It should be quite a lot. The current rent for a two-bedroom apartment in our community is only one or two thousand. It depends on the decoration." Aunt Hua replied naturally: "The house I bought in the provincial capital a while ago only costs about one or two thousand a month." Renting for three to four thousand is actually not cost-effective..."

"Let me tell you, when we were farmers, ten thousand yuan was too much. Now I don't know. I just look at the money entering the account all day long and don't know how much is too much."

"You are a rich town, so there must be many."

"I heard from my son that he solved a case at work two days ago and was rewarded with 10,000 yuan. I thought, are the rewards from work units so much now? Hahaha, I guess it's quite a lot... "

Aunt Hua's tone changed when she heard this: "Is there such a high reward for being a police officer?"

"I told you, I've never heard of it. However, he solved a case that happened 20 years ago. It's called a cold case on TV."

"Hey, that's awesome."

"Well, their leaders also praised him. I just wanted to ask, don't worry about the depreciation of money in the past two years..." Jiang Fuzhen laughed a few times and hung up the phone.

Jiang Yuan looked up at his father and said, "Don't you go to the vegetable market every day?"

"Just to confirm. You don't know how bad inflation is. By the way, I forgot to ask..." Jiang Fuzhen picked up his phone on the spot and replayed it.

After a short pause, you hear a mechanical tone from your phone: The number you dialed is currently on a call...

Jiang Fuzhen showed a rich smile.

…

the next day.

When Jiang Yuan arrived at the unit, he launched an attack on the second fingerprint.

To no avail.

The third day.

Continuing from yesterday, to no avail.

The fourth day.

Jiang Yuan gave up on the second fingerprint and started comparing the third fingerprint.

Compared with the previous two fingerprints, although this fingerprint is also incomplete, the details of the residual pattern are relatively rich. It is equivalent to a hedgehog with muscular fur and plump skin spines.

Jiang Yuan then compared more details.

Starting point, divergence point, small eye, small hook, connection point...

Jiang Yuan made the fingerprint image very large, and only part of it was displayed on a screen. He moved the mouse gently and outlined it carefully.

Wang Zhong finished his daily work and ran over to take a look as usual.

He stared at Jiang Yuan's operations, feeling that he could do it, but also that he couldn't.

It's like facing a physics problem. You know all the formulas, and it feels like what he wrote is reasonable, but if you want to think about it yourself, it feels like your head is caught in the door.

Wang Zhong looked at it and fell asleep again.

Hearing Jiang Yuan say "win", Wang Zhongcai opened his eyes like a magic toad and asked: "Did you win?"

"It should be this one." Jiang Yuanxu pointed at the screen.

Wang Zhong leaned over in surprise and compared nervously while Jiang Yuan was checking again.

"How is it?" Jiang Yuan asked politely.

"It seems... you won the competition?" Wang Zhong didn't know how to answer. For him, it is very common to find fingerprints in a new case, but it is unusual to find fingerprints in an old case, even if it is an existing case.

If Wang Zhong had won the competition himself, he would probably jump up and shout twice now.

But Jiang Yuan obviously had no intention of celebrating.

For him, the fingerprints in this case cannot be said to be simple, but they are not difficult either.

This is actually normal. Regardless of what Wang Zhong said about the series of thefts, a series of thefts still cannot be compared with the "Liu Yu Injury Case", a serious injury case with great social impact. The fingerprints involved were at least carefully screened by experts from Qinghe City.

This "series of oil theft cases in high-speed service areas" does not sound high-level at first glance. Although it involves a slightly wider area, the trace inspections involved in the investigation were mainly trace inspections by the county bureau. Although a certain county bureau may also have experts, cases may not necessarily be assigned to the hands of experts.

For example, in Ningtai County, Wang Zhong is doing it. If it can't be done, it just can't be done.

"This person seems to be in prison." Jiang Yuan opened the information of the suspect and saw a traditional prison photo with small eyes, a flat nose, a lean mouth, and slanted eyebrows.

"I was imprisoned a month ago. There is no conflict in time." Wang Zhong took a quick look, breathed a sigh of relief, then looked at the cause of the case and said: "Look, he fought with someone in a nightclub and caused minor injuries. He was in the nightclub The money spent was probably earned from stolen oil.”

Jiang Yuan asked: "What about now?"

"You call Team Huang. With the improved evidence, I think we can bring out a few gang members." Wang Zhong said flatly: "If Team Huang hears that you have solved another case, he will be very happy."

Jiang Yuan smiled: "I've been a little busy lately, and I don't have any other cases..."

"You can't say this." Wu Jun, who was originally carefree, suddenly changed his face when he heard Jiang Yuan's words.

Jiang Yuan was stunned for a moment, then smiled sheepishly: "I forgot, you can't say you are too busy, right?"

"Don't say this word..." Wu Jun lamented, lowered his head and glanced at his phone unconsciously, as if it would ring at any time.
