Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 196 The Headless Case

There are 83 cases, excluding the case in Haizhou City and the case that Lu Chuan had won yesterday, there are more than 70 cases left.

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

The detection of any case not only represents the detection of the case of that year, but also represents the end of an era.

The murder of a miner in Meishan ten years ago was just one of them.

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

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

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

Complain.

Since Meishan Coal Mine was restructured and acquired by Meishan Mining Group ten years ago, Li Hong has changed from an ordinary safety supervisor to a thorn in the side who sues every day.

And Chen Hu, who used to be a colleague, has been promoted step by step from the safety officer to become the safety director with the most say in the coal mine.

In any coal mining industry, the most important position is neither working nor marketing.

Coal is not worried about selling.

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

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

Today, the entire Meishan Coal Mine is covered by a tense and confused atmosphere.

"Have you heard that Mr. Chen was arrested?"

"Last night, I took it away at the wine table where I had dinner with the boss."

"Say it's the same as the case ten years ago..."

"Ten years ago...then Li Hong..."

In the ten years since Li Hong filed the lawsuit, the main body of the lawsuit was the Meishan Mining Group. According to the people in the mine, it was eating other people's food and smashing other people's pots.

These years, if it wasn't for Chen Hu's care, Li Hong would have been fired long 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 complaints are all true. They did a lot of illegal things to embezzle assets back then. The people in the mine who were in league with them were all promoted. Those of us who are against the tune have become like me..."

Li Hong's notes provided an important basis for the investigation of the case.

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

"Back then, my superior asked me to forge a safety report. When I was talking in the mine, he overheard me, so I had no choice but to kill..."

Behind Chen Hu's murder was a hidden mine disaster.

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

Facing the death sentence, Chen Hu explained everything.

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

The Meishan Criminal Investigation Detachment is busy.

In the fingerprint meeting 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 with a muddy background.

Because of this kind of fingerprints, it is relatively easier to use mathematical methods to process them through computers.

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

When the corpse was discovered, it was already highly decomposed, showing a state of gigantism.

The giant view state is a late change of the corpse, a highly decomposed corpse, and it is difficult to accurately identify the relevant information of the deceased.

The identity of the deceased was not confirmed through fingerprint collection and DNA comparison.

However, the murder weapon used by the murderer to kill the deceased remained in the body. It was a fruit knife, and half a blood fingerprint was extracted from the handle of the knife.

The head was cut off by a sharp weapon, and it has not been found since the incident. 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 with clues and it's very direct, but after so many years, the case has not been solved.

After dragging the fingerprint into the PS software, Lu Chuan began to process it.

"Ms. Lu... you are?"

PS software is basically used by those who play fingerprints. Many of the experts present can even be said to be relatively proficient in PS software.

However, compared to Lu Chuan's operation, everyone's so-called proficiency seems to be just knowing how to use it?

What Lu Chuan is doing is image layering, but unlike general image layering, Lu Chuan uses binary image transformation.

By digitizing the fingerprint image and then using a formula to distinguish the data of different coatings, the effect of separating the coatings is achieved.

"The layering of the image in this way is more thorough. Starting from the root of the data is far better than the surface layering of the software itself, and the final image obtained is clearer."

"Oh……"

A few people behind him responded with half-understanding, and more people frowned.

What are data roots?

Lu Chuan did not hide his secrets, and while doing data layering, he explained to everyone: "Here we use a relatively simple sine function transformation, and then use Fourier transformation to connect..."

Therefore, with the in-depth explanation of Lu Chuan, fingerprint identification and analysis gradually evolved into a mathematics class.

"Is this transformation deterministic?"

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

Lu Chuan paused while typing on the keyboard.

"There are certain rules, but the main reason is that the user's mathematical foundation has higher requirements."

When Lu Chuan studied mathematics before, he was still relatively good.

But compared to the mathematics skills in the advanced fingerprint identification and analysis skills rewarded by the system, it is still nothing.

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

Moreover, the use here is not an ordinary test question, it needs to program the computer by itself, and then analyze the uncertain variables.

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

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

Academic and practical application are never the same thing.

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

Not so difficult.

Gradually, those who didn't understand went back.

Everyone has their own skills that they are good at, and others can't learn it by themselves, so let's study their own.

"Ding!"

The pleasant reminder sounded, and Lu Chuan was darkly excited.

The success of the comparison is displayed on the screen, which is the recognition of Lu Chuan's two hours of hard work.

The murderer of Yunfeng City's No Head case, the comparison was successful!

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

"Is this the match?"

Zhang Tao smacked his lips and poked at the colleague next to him: "Old Li, your unsuspecting case has been solved!"

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

I always feel that just a little bit can be won in one fell swoop.

As a result, Li Yunwei was stabbed at the moment when he thought he was about to ascend to the clouds.

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