Chapter 83: Identification

Changyang City.

The sun was blazing, traffic was rolling, smooth black silk was everywhere, and long white legs were swinging.

Jiang Yuan opened his eyes, climbed up from the hard bed, and waited for a few seconds before realizing that he had moved into the guesthouse of the provincial department.

Pulling open the curtains, there was a lush green plant outside, showing a beautiful picture of watering.

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

After coming to Changyang City and participating in the "Provincial Fingerprint Information Case Solving Campaign" for two days, Jiang Yuan already knew that the laziness in the morning was the most relaxing moment of the day, and almost the only relaxing moment.

When he got out of this door, he had to hold his head high and maintain his police appearance and discipline. As for the office, it was another kind of terrifying casualness.

You can eat, drink, wear and shout at will, as long as you can be more casual than the fingerprint.

More than 30 trace inspectors from all over the province gathered together and worked hard. Each person looked at 3,000 fingerprints a day to reach the average.

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

In fact, Zhu Huanguang can look at fingerprints for 14 hours a day, an average of 500 fingerprints per hour, equivalent to 8 fingerprints per minute, and each fingerprint is only observed for about 8 seconds.

And at this intensity, he has solved 4 cases in other cities and counties.

According to tradition, or according to the normal development law of fingerprint case-solving battles, the number of cases solved must increase with the passage of time. Because fingerprint experts will gradually become more familiar with fingerprints, the more cases they will solve in the future.

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

In the past, fingerprint experts worked independently in various units, and from time to time they had to do some chores that ordinary colleagues in the unit could do - such as meetings. They can't concentrate on fingerprint matching.

Fingerprint battles are different.

During fingerprint battles, the provincial department or ministry provides food and accommodation, round-trip travel expenses, and business trip subsidies, and pulls fingerprint experts from all over the country. There is nothing to do, just constantly matching fingerprints every day, so as to concentrate on accumulating familiarity with fingerprints and continuously increasing the probability of solving cases...

The fingerprint experts are also very happy. They are all people in their thirties or forties. They sleep in dormitories and eat in canteens. They don't have to worry about whether their wives are happy or not, whether their children have done their homework, whether their parents quarrel, and even less about the faces of their leaders and the thoughts of their colleagues. What they have to face every day are dozens of familiar and unfamiliar faces, hundreds of familiar and unfamiliar fingerprints, and the "backlog case solving rankings" on the wall. I don't know how comfortable their lives are.

And the reason why there is a time limit for such a good thing is mainly because the provincial department is worried that the experts will be really exhausted.

Of course, the status and efficiency of solving cases of experts are also different. For example, Jiang Yuan, on the "Ranking List of Backlog Cases Solved" hanging in the office, the number of backlog cases solved behind Jiang Yuan's name is clearly 0, and he ranks last with more than ten other trace inspectors.

However, Jiang Yuan does not seem to be in a hurry. When he arrives at the office, he first makes himself a cup of tea and then looks around.

Comrade Zhu Huanguang is filing, and the fingerprints on the computer screen are brushing. The female comrade next to him is putting eye drops on herself. The fat colleague next to him is eating pancakes, and the screen in front of him is also brushing fingerprints.

To be honest, the state of this office looks like a college entrance examination study room, the kind that is super old.

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

He bought half a box of Zhonghua from Jiang Yuan yesterday, and they became close friends.

Jiang Yuan smiled and turned around and said, "You haven't broken zero either?"

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

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

Soon, in the study room... no, in the office of the "Provincial Fingerprint Information Case Solving Campaign", there was only the sound of typing and mouse.

Jiang Yuan leaned back in his chair and stared at the computer screen. He drew a feature point once and looked at many pairs 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, with a limited number, a limited number of places, and an entry and exit mechanism.

In short, small cases are not accepted, those that have not been settled for a long time are not accepted, and those that have not been matched many times by their own trace examinations are not accepted.

Therefore, the fingerprints that enter the fingerprint battle are either fingerprints of major cases or difficult fingerprints with high difficulty. Some fingerprints may have only one-fifth or even one-sixth of the normal fingerprints, and they still need to be matched.

For these difficult fingerprints, I believe that the fingerprint matching system is meaningless.

This kind of ordinary trace detection will do, and there is no need to fill out various report forms and submit them to experts for processing.

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

This is equivalent to maximizing the role of people, or the workload of people.

The fingerprints that the experts snapped and snapped, which might have been screened out by software in the past, are now all screened by manpower, and the manpower must be the most advanced in trace identification.

But it is not as good as using the software system normally, most of the backlog cases are impossible to match.

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

Criminal investigation technology also requires cost and input-output, but sometimes, criminal investigation would rather spend millions to solve the case at any cost.

This logical conflict has troubled the experts from the beginning.

However, this trouble did not affect Jiang Yuan.

He just wanted to simply match the fingerprints, and he did so.

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

In Jiang Yuan's mind, a fingerprint he had seen yesterday immediately emerged.

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

Although the fingerprint that was just swiped had no connection with the fingerprint I saw yesterday in the software system - it appeared because Jiang Yuan compared it with a robbery case.

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

Both fingerprints were very blurry.

Although both have a very obvious parallelogram shape structure to the human eye, 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 consistent.

This means that one of the fingerprints is blurred at the key point and may be seriously deformed. At the same time, the other fingerprint may be the same.

Jiang Yuan thought and compared while he was thinking. After confirming again and again, he lightly clicked the right mouse button on the right side to mark it: confirm the same.

In every corner of the office, the sound of "ding dong" suddenly rang.

The experts present who did not turn off the reminder all learned a new piece of information: someone had identified a certain fingerprint as identical.
