After the ordinary trace inspection for latent fingerprints is completed, the results are handed over to fingerprint experts for review. Some provinces and cities have specialized organizations such as "Fingerprint Expert Committees" for fingerprint review work, but most consider it a waste of expert manpower and instead use a model where a dedicated person collects the fingerprints and then assigns them to the experts for review, such as in the case of Shannan Province. However, during the fingerprint battle, there is no need to go through the trouble of finding other experts after skipping over these experts. This would raise questions about my expert qualifications, even though I actively participated in the provincial department's organized battle.

At the same time, it is also to increase everyone's work enjoyment and help everyone learn from each other. During the fingerprint battle, the fingerprint review is done by the experts present reviewing each other. As long as 11 experts complete the review and have a majority vote of "agreement and recognition," the fingerprint comparison for this time is considered successful. The provincial fingerprint post can send a letter to the local criminal investigation team to organize personnel for arrest.

However, even if 11 experts complete the review, the fingerprint match will still exist in the system, waiting for other experts to review it. If subsequent experts continue to choose "agreement and recognition" or the majority chooses "agreement and recognition," it will not affect the subsequent operation of the fingerprint match. However, if someone chooses "recognition exclusion," it may enter a new round of discussion and judgment in the entire process.

Because of this, the judgment of the "recognition exclusion" option must be very cautious and have strong confidence and judgment basis before someone chooses it.

The old man Li Zemin next to Jiang Yuan clicked on the system's message prompt for the first time. He usually enters the state later, also because he's older and can't keep up with the young people. So, in the first few days, he got used to slacking off and only slowly started to exert himself after three or four days of the fingerprint battle.

However, Li Zemin is still very concerned and curious about the identification of other fingerprint experts. In the target fingerprint database of the fingerprint battle, any fingerprint is not simple. Most fingerprints have been read and compared by experts. No county bureau will easily give the key fingerprints of a major case to the provincial department without trying them out multiple times.

And the experts in the fingerprint battle are naturally not easy to deal with either. As the leader of a province in the trace inspection position, they have accumulated a lot of experience and professional skills. They will first choose their most proficient method and select the fingerprints they are most likely to match successfully, then spend several hours or even days trying to match the fingerprints.

Most fingerprint experts can complete one or two such matches during the 14-day fingerprint battle, which is considered relatively successful. In order to complete such a match, fingerprint experts naturally have to use all their skills and abilities. Li Zemin's favorite thing to watch is these colleagues around him, using all their strength and pretending to be nonchalant.In the system message, there were a total of 12 prompts, representing 12 unsolved fingerprint cases.

Li Zemin had already agreed to the first 11 prompts. There was nothing to say about it. The first batch of fingerprints were carefully studied and self-checked by experts. Few people were willing to spend a long time to confirm someone else's exclusion.

As for the latest system message, Li Zemin was not surprised by the two fingerprints that appeared when he clicked on it. With a little judgment, he could determine that they were the same.

Positive comparison was relatively easy. It was like asking an ordinary person to find the two pigs that looked the most alike from a group of pigs. That was naturally difficult. But if you brought two pigs over and asked if they looked alike, most people could give a reliable answer.

Not to mention experts.

Li Zemin lightly operated the mouse and clicked "agree" on the latest system message.

Then, Li Zemin looked at the specific fingerprint information.

At this point, Li Zemin noticed that the person who signed the "identification as the same" of the fingerprint was Jiang Yuan, who was next to him.

"Wow, you're lucky," Li Zemin muttered, then continued to look at the fingerprint.

The first thing Li Zemin saw was the quadrilateral fingerprint structure. He couldn't help but smile, praising Jiang Yuan's luck.

However, when Li Zemin looked at the detailed feature points of the two fingerprints, his brow furrowed.

Wow, wow...

Li Zemin couldn't help turning his head to look at Jiang Yuan and said, "Did you match this fingerprint by software?"

The software system's matching had rules. The most basic principle was the matching of how many feature points, and the more advanced could be a scoring system that released the result when it reached a certain score.

However, Li Zemin looked at the two fingerprints, and they couldn't match the feature points together.

But in terms of human standards, or rather, not just comparing feature points, but comparing the structure of points, lines and surfaces, it could indeed be identified as the same.

This could be said to be a very honest way of fingerprint matching. In the era before computer systems automatically matched fingerprints, everyone used similar methods.

It's just that it's rarer now.

Jiang Yuan's eyes were fixed on the screen, operating the mouse while saying, "When I was looking at other fingerprints, I suddenly saw it and compared it, and it matched."

"Well, you remember fingerprints well," Li Zemin laughed. What Jiang Yuan said was quite understandable. It was normal thinking to occasionally compare such a special fingerprint with a quadrilateral structure.

But when it came to fingerprint structure, it was such a small area of one square centimeter. In addition to quadrilateral fingerprints, there may also be pentagonal, hexagonal, circular and other structured fingerprints. It was necessary to have a deep memory of fingerprints to achieve this point.

"Lucky," Jiang Yuan responded politely.Li Zemin laughed and pointed at Jiang Yuan with his hand, saying, "Well, you're in luck. You're so young and you've already made a contribution in the fingerprint battle. You won't have any pressure from now on. We old guys will take on the pressure."

As he spoke, someone else agreed with Jiang Yuan's "identification of the same". The "unsolved cases solved ranking list" on the wall in front of the office was immediately updated.

Jiang Yuan's name rose more than twenty places in one breath, coming to the middle position.

And on his right side, there was undoubtedly a "1" in the contribution section.

Li Zemin's name still lagged behind, with only a "0" in the contribution section, but he was not in a hurry. It was always easy to go from 0 to 1.

Li Zemin even had time to continue looking at the case he had just identified.

A quick look at "pawread.com" will leave you more fulfilled.

"It's the case of Qiang Duojian's rape of underage girls in Miaohe County. This person has committed three crimes, and I feel familiar with it!" Li Zemin took a deep breath and shouted.

Many people looked over, but most of them just heard the noise and were slightly moved. There were many major cases accumulated by the provincial department, and people's memories were always limited.

However, there were forensic experts from Miaohe County in the office, and they couldn't help standing up and coming over to ask: "Did you solve case 515?"

"It wasn't me, Jiang Yuan solved it. It was from the Ningtai County Bureau." Li Zemin stepped aside and introduced Jiang Yuan, "Qian Mingyu is a fingerprint expert from Miaohe County and has been in the police force for 20 years."

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

Jiang Yuan said straightforwardly, "I found a square fingerprint and identified it as the same after comparison."

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

Li Zemin gave up his position and took a look himself, saying, "It's from Wanxiang City, a bit far away."

Wanxiang City and Miaohe County were in the west and east respectively, and they could be considered as crossing the border of Shannan Province.

Qian Mingyu nodded heavily, then nodded to Jiang Yuan and took out his phone, saying, "I'll tell our team leader that this case has been bothering us in our county for a long time."
