National Forensic Doctor

Changyang City.

The scorching sun was in the sky, the traffic was rolling, the smooth black silk stockings were wandering all over the street, and the long white legs were swinging back and forth.

Jiang Yuan opened his eyes and got up from the hard bed. After waiting for a few seconds, he realized that he was staying in the guest house of the provincial government.

Open the curtains, and there is a lush green plant outside, showing a beautiful picture of being willing to water.

Jiang Yuan stretched out, slowly folded the quilt, and then washed and dressed at an even slower speed.

Two days after arriving in Changyang City to participate in the "Provincial Fingerprint Information Solving Crime Battle", Jiang Yuan already knew that laziness in the morning was the most relaxing moment of the day, and almost the only relaxing moment.

When he leaves this door, he will hold his chest and head high and maintain his police appearance and discipline. As for the office, it's another kind of terrifying casualness.

You can eat as much as you like, drink as much as you like, dress as you like and shout as you like, as long as you can match the casualness of fingerprints.

More than 30 trace inspectors from all over the province gathered together to examine the matter to the death. Only by reading 3,000 fingerprints per person per day can we reach the average level.

Zhu Huanguang, a policeman from Changyang City, is the king of fingerprints in this province. He sees more than 6,000 fingerprints every day, which is incredible to laymen.

In fact, Zhu Huanguang can read fingerprints 14 hours a day, averaging 500 fingerprints per hour, which is equivalent to reading 8 fingerprints per minute. Each fingerprint is only observed for about 8 seconds.

With this intensity, he has solved 4 cases from other cities and counties.

According to tradition, or in other words, according to the development rules of normal fingerprint solving battles, as time goes by, the number of solved cases must be more and more. Because fingerprint experts' familiarity with fingerprints will gradually increase, more and more cases will be solved as time goes by.

This is also the reason why fingerprint crime solving battles are constantly promoted.

In the past, fingerprint experts worked independently in various units. From time to time, they also had to do chores that ordinary colleagues in the unit could do - such as holding meetings. I couldn't concentrate on fingerprint comparison.

The fingerprint battle is different.

During the fingerprint competition, the provincial departments or ministries will provide food, accommodation, round trip expenses, and business trip subsidies. Fingerprint experts from all over the country will be invited to come over. If nothing happens, they will continue to compare fingerprints every day, thus concentrating on accumulating familiarity with fingerprints. , constantly increasing the probability of solving the case...

The fingerprint experts are also very happy. They are all in their thirties or forties. They sleep in dormitories and eat in the cafeteria. They don’t have to worry about whether their wives are happy or not, whether their children’s homework is done, or whether their parents are arguing. When quarreling, let alone looking at the boss’s face and colleagues’ thoughts, what we have to face every day are dozens of familiar and unfamiliar faces, hundreds of familiar and unfamiliar fingerprints, and the “ranking list of solved cases” on the wall. I don’t know how comfortable life is.

The reason why there is a time limit for such a mutually beneficial thing is that the provincial department is worried that it will really exhaust the experts.

Of course, the status and efficiency of solving crimes among experts are also different. For example, Jiang Yuan, on the "ranking list of backlogged cases solved" hanging in the office, after Jiang Yuan's name, the number of solved backlogged cases is clearly 0, which is tied for last place with more than a dozen other trace inspectors.

However, Jiang Yuan didn't seem to be in a hurry. When he got to the office, he made himself a cup of tea first and then looked around.

Comrade Zhu Huanguang was scrolling, and the fingerprints on the computer screen were swiping. The lesbian next to me is taking eye drops for herself. The fat colleague next to me was eating pie, and the screen in front of him was getting fingerprints.

To be honest, the state of this office looks like a college entrance examination study room, the kind for those who are very old.

"Xiao Jiang, you haven't broken zero yet, aren't you in a hurry?" The uncle at the next station looked over with a smile.

Yesterday, he drank half a box of Jiang Yuan's Chinese food and became irresistible.

Jiang Yuan smiled, turned around and said, "Don't you also have broken zero?"

"I'm used to it." The uncle smiled and said, "Wait for you."

"Then I'll catch up quickly." Jiang Yuan finished his daily polite work, turned around and stared at the screen.

Soon, in the study room... no, in the "Provincial Fingerprint Information Solving Crime Battle" office, there were only the sounds of typing on the keyboard and the mouse.

Jiang Yuan leaned back on the chair and stared at the computer screen, drawing feature points once and looking at many sets of fingerprints.

The fingerprint comparison during the fingerprint battle is completely different from the daily fingerprint comparison. First of all, the fingerprints that can be selected for the fingerprint battle are all selected from various places. There are limits on quantity, quotas, and entry and exit mechanisms.

To put it simply, we don’t want small cases, things that haven’t settled over time, and things that have been matched multiple times through their own trace inspections.

Therefore, the fingerprints that enter the fingerprint battle are either the fingerprints of major cases or the more difficult and difficult fingerprints. Some fingerprints may be one-fifth or even one-sixth of a normal fingerprint, and you still have to try to match them.

For these difficult fingerprints, it makes no sense to trust the fingerprint matching system.

This kind of thing that ordinary trace inspections can do, there is no need to fill out various report forms and then submit them to experts for processing.

Because of this, when fingerprint experts in the office face difficult fingerprints, the number of candidate fingerprints is directly above 200 or even 300.

It is equivalent to maximizing the role of people, or in other words, the workload of people.

Experts took pictures of fingerprints. In the past, they might have screened them away with software, but now they have to go through them all again manually, and they have to be the most advanced human resources in trace identification.

But it is not as good as using the software system normally. Most of the backlog cases are impossible to win.

This is also one of the great differences between criminal investigation technology and ordinary technology. Ordinary technology may be more cost-effective and willing to give up some functionality to ensure cost and effectiveness.

Criminal investigation technology also requires cost and input and output, but at some point, criminal investigation would rather spend tens of thousands of dollars to solve the case regardless of the cost.

This logical conflict has troubled experts from the beginning.

However, this trouble did not affect Jiang Yuan.

He just wanted to simply match the fingerprints, and that's exactly what he did.

At this time, a fingerprint that looked like a parallelogram crossed Jiang Yuan's eyes.

In Jiang Yuan's mind, a fingerprint he saw yesterday immediately appeared.

The fingerprint I saw yesterday had a similar parallelogram shape, which is also a very rare fingerprint shape. It was owned by a very rare perverted rapist.

Although the fingerprint just swiped has no connection with the fingerprint seen yesterday in the software system - it appeared because Jiang Yuan compared a robbery case.

However, Jiang Yuan's first thought was to combine the two together and compare them manually.

The two fingerprints were both very blurry.

Although to the human eye, both have a very obvious parallelogram shape structure, the software system obviously does not think so. Just looking at the grooves, points, and warps inside, the overlap between the two is less than 30%.

But the trend of the lines is the same.

It means that one of the fingerprints is blurred to a critical point and may be severely deformed. At the same time, the same may be true for the other fingerprint.

Jiang Yuan thought and compared. After confirming again and again, he right-clicked the mouse on the right side and made a mark: identified as the same.

A loud "ding-dong" sound suddenly sounded from every corner of the office.

The experts present who had not turned off the reminder learned a new piece of news. Someone identified a certain fingerprint as the same.
