Chapter 86: Battle Results

Li Zemin clicked on the prompt of the new message, clicked another layer, and saw two fingerprints quietly appearing on the left and right sides of the screen.

However, unlike the fingerprints that Jiang Yuan "identified as the same" last time, the two fingerprints this time, the one on the left can be said to be blurry to the sky.

Li Zemin couldn't help rubbing his eyes and said in surprise: "It's all flowered like this?"

"The blur is actually mainly noise. After processing, it's not that exaggerated." Jiang Yuan said simply.

Li Zemin clicked his tongue twice, leaned against the left side of the screen, and looked carefully.

After a while, Li Zemin raised his head with a click of his tongue and clicked agree on the right side of the new message.

He also relied purely on lines and patterns to identify identity, but he hadn't used this method for a while.

Looking up again, Jiang Yuan's battle result quantity had already become "2", and 11 experts had already identified it as the same.

"Good fellow, good luck." Li Zemin muttered, and then continued to look at the fingerprints.

Li Zemin first saw the quadrilateral fingerprint structure. He couldn't help but smile, and then praised Jiang Yuan's luck.

However, when looking at the details of the feature points of the two fingerprints, Li Zemin's brows couldn't help but wrinkle.

Good fellow, good fellow...

Li Zemin couldn't help but turn his head, look at Jiang Yuan, and say: "The fingerprint match you made, isn't it chewed out by software?"

The matching of software systems has its rules. The most basic principle is the matching of how many feature points, and a more high-end one can be a scoring system, which is released when it reaches a certain score.

But Li Zemin looked at the two fingerprints, put them together, and couldn't even put together the feature points.

However, looking at it from the human standard, or not just comparing feature points, but comparing point-line-surface and other structures, it is indeed possible to identify identity.

This can be said to be a very honest way of fingerprint matching. In the era without computer system automatic matching, everyone used similar methods.

It's just rarer now.

Jiang Yuan's eyes stared at the screen, operating the mouse while saying: "It's when looking at other fingerprints, I suddenly saw it, pulled it over to compare, and it matched."

"Then your fingerprint memory is quite good." Li Zemin smiled. He understood what Jiang Yuan said, and it is normal thinking to encounter such a special fingerprint with a quadrilateral structure occasionally and compare it.

But if you really talk about fingerprint structure, in such a small fingerprint, a 1cm square area, besides the quadrilateral structure fingerprint, there may be pentagonal, hexagonal, circular, etc. structure fingerprints. You have to have a deep memory of fingerprints to do this.

"Good luck." Jiang Yuan responded, very perfunctory.

Li Zemin laughed, pointed at Jiang Yuan with his hand, and said: "This is good now. You are young and came to the fingerprint battle, and you already have a result. There is no pressure for the next step, and the pressure is all on us old guys."

He said while talking, and someone agreed to Jiang Yuan's "identify identity" again, and the "Cold Case Solving Ranking List" projected by the projector on the front wall of the office also made an update immediately.

Jiang Yuan's name rose more than 20 places in one breath and came to the middle position.

And on the right side of his battle results, a "1" appeared without a doubt.

Li Zemin's name still fell behind, and there was only a "0" in the battle results, but he was not in a hurry. From 0 to 1, it has never been difficult.

Li Zemin even had time to continue to look at the cases that had just been identified as the same.

"It's the rape case of a minor girl in Miaohe County. This person has committed crimes in three places, I said it was a bit familiar!" Li Zemin hissed and shouted.

Many people looked over, but most of them just heard the movement and were touched. There are many major and important cases in the cold cases accumulated by the Provincial Department, and human memory is limited after all.

However, there were trace inspectors from Miaohe County in the office, who stood up at this time and walked over directly to ask: "You broke 515?"

"Not me, Jiang Yuan matched it. Ningtai County Bureau's." Li Zemin let go and helped Jiang Yuan introduce: "Qian Mingyu is a fingerprint expert in Miaohe County and has 20 years of police experience."

"20 years is useless. I have been staring at the 515 case for several years. The three victims were all middle school students. After the case happened, the parents came to our bureau many times. Later, the victims couldn't stay in the county, and they moved away one after another, and occasionally called to ask..." Qian Mingyu was slightly younger than Li Zemin, and sighed at this time.

Jiang Yuan said plainly: "I encountered a quadrilateral fingerprint, compared it, and identified it as the same."

"Let me see, where is the person?" Qian Mingyu was more familiar with Li Zemin and looked directly at his computer.

Li Zemin gave up the position, took a look at himself, and said: "Wanxiang City's, it's a bit far."

Wanxiang City and Miaohe County, one west and one east, can be considered to span the boundary of Shannan Province.

Qian Mingyu gave a heavy "mm," nodded to Jiang Yuan, took out his mobile phone, and said: "I'll tell our brigade captain, this case has been troublesome in our county for a long time." ===== CHAPTER 87 =====

Seeing Jiang Yuan's attitude, Li Zemin felt he probably didn't care much about this matter. Come to think of it, everyone was here to serve the people; if the machine was exhausted, didn't that just show the person's own level of effort was deeper? As long as results could be produced, it might even be better to call the Department Director over to witness it.

Just as he was thinking this, he saw Yang Ling, the section chief of the fingerprint post, arriving in the office.

The provincial bureau's fingerprint post was a section-level establishment with only single-digit personnel, mainly serving to transmit information from above and below. Activities like the fingerprint battle were also organized and arranged by the fingerprint post.

Yang Ling, the section chief of the fingerprint post at the Shannan Provincial Bureau, was in her thirties. She was a top student who had graduated from the Criminal Police Academy, possessing both technical skills and ability, and her social skills were also up to par. She easily commanded a group of middle-aged and elderly trace evidence examiners with high myopia to get things done.

Upon entering the office, Yang Ling was all smiles. When she reached Jiang Yuan, she whispered, "Teacher Jiang, do you have a moment?"

Using the title "Teacher" was extremely polite.

Jiang Yuan looked up and saw it was Yang Ling. He returned the smile, though he hesitated slightly and said, "I'm really sorry, could you wait a minute? This one looks like it has some promise."

"Understood, understood." Yang Ling nodded immediately. During the fingerprint battle, reading fingerprints was the most important thing; she had no need to race against time.

Out of politeness, Yang Ling simply walked around the front of the desk and stood by Jiang Yuan's side.

From her position, she could also see the fingerprint image on Jiang Yuan's screen.

The two images on the left and right indeed had quite a few similarities.

Yang Ling's expression immediately became much more serious.

The cases here, if placed outside, were each cases that would tug at many people's heartstrings. Even working at the provincial bureau and seeing various cases every day, Yang Ling did not dare to have the slightest bit of contempt.

Moreover, don't look at the fact that the provincial bureau held a fingerprint battle every few months, gathering dozens of fingerprint experts to work their fingers to the bone for half a month; if they could eventually solve more than 50 cases, they would dare to boast about it extensively.

Averaged out per fingerprint expert, it was only about one case per person.

And everyone whose salary has been averaged out should know that an average of one case per person means that many experts go home with a goose egg.

A goose egg is nothing; if an expert could definitely have results after working hard for 14 days, there wouldn't be so many cases accumulated at the provincial bureau.

Correspondingly, since the fingerprint Jiang Yuan was working on now had promise, Yang Ling dared not and was unwilling to influence him no matter what.

"Control Guard is Here"

Jiang Yuan checked left and right, and in the end, he even opened the original blood fingerprint to look closely.

About two or three minutes later, Jiang Yuan submitted the "Identity Confirmation," let out a sigh, looked at Yang Ling, and said, "Sorry, I just happened to be at the final step."

"It's okay, it's okay." Yang Ling waved her hands repeatedly, her eyes darting to Jiang Yuan's screen again.

At this moment, she saw the number of experts "agreeing" with his "identity confirmation" on the bottom right of Jiang Yuan's screen growing rapidly.

Many people had noticed that Section Chief Yang of the fingerprint post had arrived, and it was only natural for them to take a look at the newly updated news.

And after seeing the new news, agreeing with Jiang Yuan's "identity confirmation" was a matter of course.

On the wall in front of the office, the battle results ranking projected by the projector showed Jiang Yuan leaping to second place, trailing only Zhu Huanguang, who was in first place, by one result.

"You were looking for me just now, is there something?" Jiang Yuan looked at Yang Ling.
