Of the 83 cases, excluding the case in Haizhou City and the case in which Lu Chuan had already been selected yesterday, there are still more than 70 left.

Every case can be said to be a sensational case in the year of the crime.

Any case is solved, which not only represents the detection of the case of the year, but also the end of an era.

The murder of a miner in Meishan ten years ago is only one of them.

Li Hong was an ordinary employee of the mine back then, but he was not ordinary.

Li Hong's life is full of challenges, doubts, and incomprehension.

Since 10 years ago, Li Hong has embarked on a road of no return in the eyes of everyone in Meishan Coal Mine, including his family.

Complain.

Since the restructuring of the Meishan Coal Mine was acquired by the Meishan Mining Group ten years ago, Li Hong has gone from an ordinary safety supervisor to a thorn in the coffin every day.

Chen Hu, who used to be a colleague, rose step by step from safety officer to become the most influential safety director in the coal mine.

In any coal mining industry, the most important position is not work, nor is it marketing.

Coal is not worried.

The most important positions in coal mines are those related to safety supervision.

Chen Hu is now the most vocal safety director in the coal mine.

And today, the entire Meishan coal mine is covered in a tense and confused atmosphere.

"Did you hear that Mr. Chen was arrested?"

"Last night, I took it away from the wine table where I was having dinner with the boss."

"It is said to be the same as the case of 10 years ago......

"Ten years ago...... That Li Hong......"

In the 10 years since Li Hong filed a lawsuit, the main body of the lawsuit was the Meishan Mining Group, which, in the words of the people in the mine, was to eat other people's food and smash other people's pots.

Over the years, if it weren't for Chen Huzhao, Li Hong would have been fired a long time ago.

Now, Chen Hu has been arrested, and Li Hong has also been taken for questioning.

The interrogation room of the Meishan Criminal Investigation Detachment.

"My complaint is true, they did a lot of illegal things in order to embezzle assets, and the people in the mine were promoted to join them, and those of us who sang the opposite tune have become like me......

Li Hong's record has provided a very important basis for cracking the case.

The evidence of Chen Hu's murder is conclusive, but he did not kill for personal vendettas.

"Back then, my superiors asked me to forge a safety report, and when I was talking in the mine, he heard it and had to kill ......

Behind Chen Hu's murder was a hidden mining accident back then.

"The purpose is to facilitate the smooth acquisition of Meishan Mining Group......

Faced with the verdict of death, Chen Hu confessed everything.

Some of the people involved in the case have retired, and some are now in high positions.

Some of the Meishan Criminal Investigation Detachment are busy.

In the fingerprint battle conference room, Lu Chuan naturally didn't know that the Meishan Criminal Investigation Detachment hadn't slept all night, and now Lu Chuan was picking the fifth case.

In fact, the so-called selection is nothing special, Lu Chuan still chose the fingerprints of the paste. ap.

Because this kind of fingerprint is relatively easy to process through a computer using mathematical methods.

Eight years ago, there was a headless corpse case in Yunfeng City.

When the corpse was found, it was highly decomposed, showing the state of a giant.

The state of the Giant's view is a late change in the corpse, a highly decomposed corpse, and it is difficult to accurately identify the information about the deceased.

At that time, the identity of the deceased was not confirmed through fingerprint collection and DNA comparison.

However, the murder weapon of the murderer who killed the deceased was left in the body, which was a fruit knife, and half a blood fingerprint was extracted from the handle.

The head was cut with a sharp weapon, and it has not been found since the incident, and the scene where the body was found was not the first scene, but the murder weapon was left in the body of the deceased.

It's a very strange scene, there are clues, and it's very direct, but after so many years, it just hasn't broke

Table.

Drag the fingerprint into the PS software, and Lu Chuan began to process it.

"Teacher Lu...... Who are you?"

PS software, basically used to play fingerprints, these experts present, many people can even be said to be proficient in PS software.

However, compared to Lu Chuan's operation, everyone's so-called mastery seems to only be able to use?

What Lu Chuan is doing is image layering, but unlike ordinary image layering, Lu Chuan uses two-digit image number transformation.

By digitizing the fingerprint image and then distinguishing the data of different coatings with formulas, the effect of separating the coatings is achieved.

"In this way, the layering of the image is more thorough, starting from the root of the data, which is far better than the surface layering of the software itself, and the final image is much clearer."

"Oh......"

A few people behind him responded twice as if they didn't understand, and more people frowned.

What is Data Roots?

Lu Chuan did not hide his secrets, and while doing data stratification, he explained to everyone: "The relatively simple sine function transformation used here is connected by the Fourier transform......

As a result, with the deepening of Lu Chuan's explanation, fingerprint identification analysis gradually evolved into a mathematics lesson.

"Is this transformation certain?"

Zhao Zhigao asked the voice of most people: "Is there a pattern?"

Lu Chuan's hands tapping on the keyboard paused.

"There are certain rules, but the main thing is that the user's mathematical foundation needs to be higher."

When Lu Chuan used to study mathematics, he was still relatively good.

However, it is still a drop in the bucket compared to the math skills in the advanced fingerprinting analysis skills that the system rewards.

Ordinary people can't remember a few changed names, let alone use them.

Moreover, the use here is not an ordinary test question, but you need to program the computer yourself and then analyze the uncertain variables.

This is a shift from the test-taking stage to practical application.

Not to mention ordinary people, even experts who specialize in playing mathematics may not be able to do it.

Academic and practical applications are never the same thing.

What's more, among the fingerprint identification and analysis experts present, many of them couldn't even remember where the keys on the keyboard were, and wanted to be like Lu Chuan......

It's not your average difficulty.

Gradually, those who didn't understand went back.

Everyone has their own skills, and if others can't learn them, then study your own.

"Ding!"

The pleasant prompt sounded, and Lu Chuan was dark and excited.

The successful comparison on the screen is a recognition of Lu Chuan's more than two hours of labor.

The murderer of the headless case in Yunfeng City, the comparison is successful!

The number of points on the hero list and the number of cases solved are updated accordingly.

"Is that a match?"

Zhang Tao smacked his lips and stabbed his colleague next to him: "Lao Li, your headless case has been solved!"

Li Yunwei is studying a fingerprint that is missing about a third, and he is now working hard.

It always feels like just a little bit, and you can win it in one fell swoop.

As a result, at the moment when Li Yunwei felt that he was going to go to the clouds, he was stabbed.

glared at Zhang Tao: "I almost came out!" What are you doing?"
