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

Chapter 138
Gao Wenxiang was stunned.

He touched his mouth, looked around at the people who went out to smoke together, and the deputy director Wang Kai standing in the middle of the conference room.

what's the situation?
Didn't the few of us just smoke two cigarettes, which is not considered fishing.

Why did the chief come here?
"The king's bureau..."

Wang Kai passed Gao Wenxiang and went straight to Lu Chuan behind him, his eyes seemed to be shining.

The fingerprint battle is held every year by the Haizhou Public Security Bureau.

But the results of the battle have not been ideal. A few years ago, when Wang Kai was still the captain of the criminal investigation detachment, he would shave his head occasionally in battles.

A group of experts from the City Bureau had no results in a week's fingerprint battle, and it was a joke to say it.

So, later everyone thought of a way to put some less difficult cases in the fingerprint battle.

In this case, although it is difficult to make breakthroughs in old cases, the data at least look better.

There can be a few figures in the work report to support the scene.

Therefore, Wang Kai did not have any illusions about this fingerprint battle.

But who would have thought that within two hours of the mobilization meeting, shocking news came from the scene of the battle.

"Lu Chuan, did you win the case seven years ago?"

Wang Kai got the news at the first time, because during the fingerprint battle, all the results of the battle will be reported at the first time.

When Sun Hao completed the first fingerprint comparison, the relevant information system was also sent to Wang Kai.

Of course, Sun Hao's successful fingerprint comparison is a small case deliberately put in.

For charging.

However, 15 minutes ago, another message about the match was automatically sent to Wang Kai's phone by the system.

Seven years ago, a murder case occurred in Haizhou High-tech Zone.

In the cultural park, a woman was killed in the bushes after working the night shift in the early morning.

The murder weapon was left at the scene, an ordinary stone.

Wang Kai was very impressed with the case at that time, which happened when he was the head of the criminal investigation detachment.

Later, although Wang Kai was promoted, he never let go of the case.

An analysis of An's case is organized every year to sort out the clues discovered that year.

It is a pity that when the crime happened that year, there was no surveillance at the scene, and there were no witnesses in the middle of the night.

The murderer should have committed the crime temporarily and randomly, and there were no clues except for a half-fingerprint collected on the stone that was twisted into a mess.

As for this fingerprint, Wang Kai specially invited experts from the provincial department to conduct an identification and analysis.

As a result, after two or three attempts, the comparison was not successful.

Now, in the fingerprint battle held by the Haizhou Public Security Bureau, it was successfully compared!
Wang Kai came to the meeting room immediately.

The case from seven years ago?

Lu Chuan nodded: "You said the case of the cultural park in the high-tech zone? Did you win the competition?"

As soon as Wang Kai mentioned the time of the incident, Lu Chuan knew it was the fingerprint he had just processed.

"I just went out to smoke a cigarette, and the system was running by itself."

While speaking, Lu Chuan walked to his computer, and there were four large characters in scarlet on the screen.

The comparison is successful!

really!

"Ju Wang, I really hit the match...the opponent is...the cleaner...Li Zhi?"

Li Zhi?

Wang Kai leaned in front of the computer and looked at the basic information of the successful target of the fingerprint comparison: "It really is him!"

"Lu Chuan, great job!"

"I'm arranging the arrest now, the case is solved, and I will credit you as the first credit!"

Wang Kai left in a hurry.

The remaining [-] or [-] people stared at each other, Gao Wenxiang stammered: "Lu... brother... did you win the murder case?!"

Several other detectives who had just met Lu Chuan also looked at Lu Chuan in surprise.

During the fingerprint battle, if the murder case is compared, as long as the person is caught and the case is solved, the criminal policeman who compares the fingerprints will at least be a third-class meritorious service!

Everyone rushed over to see Lu Chuan's fingerprint analysis.

Everyone here knows about the case of the Cultural Park in the High-tech Zone seven years ago.

Especially Gao Wenxiang, the case came from their high-tech zone.

He also participated in the detection of the case back then, so he knows better than anyone else what kind of virtue the fingerprint involved in the case is.

It was a fingerprint that was not compared in the provincial fingerprint competition.

Lu Chuan...can it be done in two hours?
Sun Hao also came over.

Fingerprint identification analysis, there is no shortcut.

A hit is a hit, and a hit is a miss.

He is also familiar with the fingerprint of the murder case in the Cultural Park of the High-tech Zone seven years ago, and has studied it more than once.

However, apparently there is no clue.

Lu Chuan didn't care too much. With his advanced fingerprint identification and analysis ability, as long as the target person's fingerprint is in the fingerprint library, there will be no problem with the comparison: "It's better luck."

It's better not to be too high-profile, Lu Chuan greeted the policemen who were smoking together just now, and didn't care if everyone surrounded him.

Of the remaining twelve murders, one was selected at random.

Four years ago, a robbery occurred in the high-speed rail new area.

The head of the household was silenced together.

According to the situation at the time, it was basically determined that the other party committed crimes on the run.

A blood fingerprint was found on the outside door frame of the deceased's house.

Because of blood stains and friction marks, the fingerprints did not show the usual texture.

It's a mark that resembles a scratch.

This is a common type of fingerprint at a murder scene, but it is also the most difficult type of fingerprint to identify and analyze.

Due to the influence of friction, the fingerprint has been completely deformed, except for some fingerprint lines at the beginning and end, there is no way to start at other places.

After dragging the fingerprints into the Snapseed photo editing software, Lu Chuan first processed the edges of the bloodstains.

Then use the software program compiled by yourself to convert the image.

Everyone heard the crackling sound of the keyboard again.

Gao Wenxiang once again saw the data flow on the screen as if it was a hacker attack.

The people behind Lu Chuan were also dumbfounded.

When they were processing the first fingerprint in Lu Chuan, they only heard the sound of keyboard tapping, but they did not see the data flow on Lu Chuan's computer screen like Gao Wenxiang.

Is this a fingerprinting analysis?

The criminal police of the criminal investigation detachment, when processing images, are not so awesome, right?

Lu Chuan continued to process the fingerprints, and more and more people were watching behind him.

A dozen or so people gradually ran behind Lu Chuan.

Especially Sun Hao, who was almost lying on Lu Chuan's back, his eyes fixed on Lu Chuan's operation.

Technically speaking, Sun Hao, as a police officer in the Technical Appraisal Center who specializes in technical investigations, must be more comprehensive than the people in the lower units.

However, he also knows that in terms of technical level, he is one level higher than others.

In the fingerprint battle organized by the city bureau, it is the limit to gain something.

But for the old murder case...

If he had that ability, the case would not be backlogged.

Therefore, Lu Chuan's ability to win the murder case means that the opponent's technology is better than him and everyone else.

If you don't steal your teacher at this time, you will look down on yourself.

This stop is almost another two hours.

A dozen or so people surrounded Lu Chuan, watching as the other party marked the fingerprints with feature points, finished the data, and dragged them into the system to start comparison.

Then, within a few minutes, the familiar, yet unfamiliar ding-dong sound sounded again!
