Gao Wenxiang was stunned. touched his mouth and looked at the people around him who went out to smoke together, as well as the deputy director Wang Kai who was standing in the middle of the conference room.

What's the situation? Isn't it just a few cigarettes smoked by myself, which is not considered fishing. Why is the director here?

"Wang Ju ......" Wang Kai crossed Gao Wenxiang and went straight to Lu Chuan behind him, his eyes seemed to be glowing. The fingerprint battle is held every year by the Haizhou City Public Security Bureau.

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

A group of experts from the sub-city bureau have no results in the fingerprint battle for a week, and it makes people laugh when they say it.

Therefore, later everyone came up with a way, and some cases with lower difficulty would be put in the fingerprint battle.

In this way, although it is difficult to make a breakthrough in the old case, the data is at least better.

There can be a few numbers in the work report to support the scene. Therefore, this time, Wang Kai did not have any illusions about the fingerprint battle.

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

"Lu Chuan, did you win the case seven years ago?" Wang Kai got the news as soon as possible because during the fingerprint battle, all the results would be reported as soon as possible.

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. Fill the number.

However, fifteen minutes ago, another message was automatically sent to Wang Kai's mobile phone by the system.

Seven years ago, there was a homicide in Haizhou High-tech Zone. In the Cultural Park, a woman was killed in the bushes after working a night shift in the early hours of the morning.

The murder weapon was left at the scene, an ordinary stone. Wang Kai was very impressed by 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. Every year, an analysis of the security case will be organized to sort out the clues found that year.

Unfortunately, at the time of the crime, there was no surveillance at the scene, and there were no eyewitnesses in the middle of the night.

The murderer was supposed to have committed the crime at random, and there were no clues except for a half-fingerprint collected on the stone that was twisted into a mess.

And this fingerprint, Wang Kai specially asked experts from the provincial department to do an identification and analysis. As a result, I did it two or three times, but the comparison was not successful.

Now, in the fingerprint battle conducted by the Haizhou Public Security Bureau, it was successfully compared! Wang Kai came to the battle conference room as soon as possible.

The case from seven years ago? Lu Chuan nodded: "You said the case of the Cultural Park of the High-tech Zone?" Matched? As soon as Wang Kai said the time of the crime, Lu Chuan knew that it was the fingerprint he had just processed.

"I just went out for a cigarette and the system is running on its own." While speaking, Lu Chuan walked to his computer, and there were four big scarlet characters on the screen.

Comparison success! Really!

"The king game is indeed a hit...... The other party is ...... Janitor...... Li Zhi? "Li Zhi? Wang Kai leaned in front of the computer and looked at the basic information of the successful target with his fingerprint: "Sure enough, it's him!" ”

"Lu Chuan, good job!"

"I'll arrange the arrest now, the case is solved, and you will be credited!" Wang Kai left in a hurry. The remaining seventeen or eight people stared, and Gao Wenxiang stammered: "Lu ...... Brothers...... You're more than a homicide?! Several other criminal policemen who had just met Lu Chuan also looked at Lu Chuan in surprise.

During the fingerprint battle, as long as the person is caught and the case is solved, the criminal police who compare the fingerprints will have at least a third-class merit!

Everyone came over and came to see Lu Chuan's fingerprint identification analysis. Seven years ago, there was no one here who didn't know about the case in the Cultural Park of the High-tech Zone.

Especially Gao Wenxiang, the case was brought out by their high-tech zone. He also participated in the detection of the case back then, so he knows better than anyone what kind of virtue the fingerprint involved in the case is.

It was in the fingerprint battle of the provincial department, and none of the fingerprints were compared. Lu...... Done in two hours?

Sun Hao also came over. There is no shortcut to fingerprint identification and analysis. If you hit, you won, and if you don't hit, you won't hit.

Seven years ago, he was familiar with the murder case in the Cultural Park of the High-tech Zone, and he had 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 there were fingerprints of the target person in the fingerprint library, there would be a problem if he didn't get it: "It's better luck." "You still can't be too high-profile, Lu Chuan said hello to a few policemen who were smoking together just now, and he didn't care that everyone was around him.

Of the remaining twelve homicides, one was chosen at random. Four years ago, there was a burglary in the new high-speed rail area.

The heads of the household were killed together. According to the situation at the time, it was basically determined that the other party was a wandering crime. On the door frame of the deceased's outer door, a bloody fingerprint was found.

Because of the blood stains and friction marks, the fingerprints did not show the common lines. Rather, it's a mark like a scratch.

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

Because of 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 in other places.

Drag the fingerprint into the snapseed retouching software, and Lu Chuan first edges the blood mark.

Then, using a software program that you have programmed yourself, you can convert the images. Once again, the crackling of keyboards was heard.

Gao Wenxiang once again saw the data flow on the screen that seemed to be the time of a hacker attack. The people behind Lu Chuan were also dumbfounded.

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

Is this a fingerprint analysis? The criminal police of the criminal investigation detachment, when processing images, there is nothing awesome, right?

Lu Chuan's processing of fingerprints has continued, and more and more people are looking behind him. More than a dozen people gradually ran behind Lu Chuan.

Especially Sun Hao, who was almost lying on Lu Chuan's back, his eyes staring at Lu Chuan's operation. Technically speaking, Sun Hao, as a policeman specializing in technical investigation in the technical appraisal center, must be more comprehensive than the people in the units below.

However, he himself knows that in terms of technical level, he is also one level above the others.

The fingerprint battle organized by his own city bureau is already the limit of being able to gain a little. But on the old murder case...... If he had that ability, the case would not have become a backlog.

Therefore, Lu Chuan's ability to compare the murder case shows that the other party's skills are not a little stronger than him and everyone else.

If you don't steal the teacher at this time, you will look down on yourself. This stop, almost two hours again.

More than a dozen people gathered behind Lu Chuan, watching the other party mark the fingerprint with the feature points, get the data, and drag it into the system to start comparison.

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