Processing a fingerprint is like performing a surgical operation.

Accurate identification of the lesion is only the first step, and it also requires superb surgical skills.

Peel off the cocoon, like stitching up a wound, stitch by stitch, without the slightest sloppiness.

As expected in advance, after this fingerprint was processed, Lu Chuan did not get a complete fingerprint.

It is less than 20% of the size of a normal fingerprint, less than a fifth, but more than a tenth.

It spreads outwards from the center point of the fingerprint, and becomes more blurred the edges the further you go.

This is already much better than Lu Chuan initially expected.

However, it still has not reached the most ideal state, if it can exceed 20%, then Lu Chuan is sure to mark enough feature points, so that the fingerprints identified and analyzed will have judicial effect.

Now, with the current size of this fingerprint, Lu Chuan can only mark nine feature points.

Although there are a lot of them, they cannot be used as evidence to lock up the suspect.

However, this does not mean that it is useless.

Lu Chuan can still use this mutilated fingerprint to compare the identity of the suspect in the fingerprint comparison system.

Then, through investigation and interrogation, it is necessary to determine whether the other party is the murderer and supplement the evidence.

Dragging the fingerprints into the fingerprint library, Lu Chuan waited for the result with some expectation.

Bite!

The System Comparison Result dialog box is displayed.

"Failed!"

Fail?

Lu Chuan frowned slightly.

Is there no target sample in the system at all, or is there a problem with the fingerprints that you have pre-processed?

If you want to verify this problem, it is not difficult.

As long as Lu Chuan changes the method, the fingerprint is preprocessed, and then compared with the original pretreatment results.

If the comparison between the two can be successful, then it is very likely that there is no target sample in the system.

On the contrary, it is Lu Chuan who has a problem with it.

Looking at the time, the afternoon was almost over.

At this time, the experts quickly entered the state because Lu Chuan was fingerprinted in two murders.

Many people have achieved results in the future.

Tian Rong, director of the Technical Appraisal Center of the Provincial Department, has even won four cases.

Although there is no backlog of homicides, it can be regarded as a major case, and in terms of accumulated scores, it has reached 18 points.

is two points away from Lu Chuan's total score of twenty points.

Two points, that is, a case of robbery or intentional wounding.

With Tian Rong's strength, if Lu Chuan doesn't gain anything next, then he will be able to catch up tomorrow.

Even, if you work extra today, it is possible to surpass it.

After Tian Rong, someone won two cases and ranked third.

The rest are all more than one case, and more than one case is not hit.

Zhao Zhigao, who was sitting next to Lu Chuan, finished a fingerprint at this moment, without exception, failed.

"Let's go, smoke one, spirit, come back and fight again!"

Lu Chuan looked at it, and many people went out to take a breather, so he answered and went out with him.

"Teacher Lu is here."

"Teacher Lu."

When Lu Chuan came out, many people took the initiative to say hello.

Even Tian Rong took the initiative to step forward: "Teacher Yuanchao has mentioned you to me more than once, saying that you are very good at bone identification and analysis."

"I didn't expect fingerprints to be so powerful."

Tian Rong is not the director of the technical appraisal center, but an expert who enjoys the treatment of the director.

In the provincial department, there is such a group of people, or a group of experts, who do not have real power, but the treatment they enjoy is not low.

"Director Tian has won the award, but he is a little luckier."

Lu Chuan responded politely, took the initiative to hand over a Huazi, and then sent one to several people around him.

Gradually, everyone gathered around

。

On the one hand, Tian Rong was originally the most skilled among all experts, and he was also an expert of the Provincial Technical Appraisal Center.

was originally the core character, and coming out to smoke is the core of everyone's chat.

After Lu Chuan came out, with his impressive record of winning two murders in one day, he must be the most influential figure in this gang.

"Haha, you're not lucky, you can enter the provincial department's fingerprint for the murder case, how can it be simple?"

Tian Rong took the cigarette, and the others echoed.

"That's it, the case of that high school student, I looked at that fingerprint the year before last, but it took two days to do it, and I didn't have a clue at all."

"Teacher Lu, don't be modest, young and promising, young and promising."

"By the way, Brother Zhao, what's going on over there in Tianzhou City?"

Chatting, Wang Youyou came over: "The case of the serial murder of the taxi started more than ten years ago, right?"

"In the provincial department's fingerprint battle library, this case seems to have been in place for more than ten years, has anyone caught it?"

Zhao Zhigao nodded heavily and spat out the last puff of smoke.

"If you are caught, the person is in Tianzhou City, and after Mr. Lu's appraisal and analysis report was transmitted, the detachment carried out the arrest."

"He can't run, even if he doesn't confess to other cases, he can't run away from the case where he left his fingerprints."

Several experts chatting together nodded, they had also heard about the serial murder of taxi drivers in Tianzhou City.

Even, a few people have studied the fingerprints of the case back then, but they have not gained anything.

But everyone also knows that this kind of case is too long and not easy to solve, especially since the murderer did not leave any clues at the scene of several other crimes.

If the other party does not admit it, it is really difficult to do.

"Okay, the boat will naturally go straight to the bridge, so we have to work harder!"

Tian Rong obviously knows the ins and outs of this case.

"Teacher Xiao Lu has solved two murders, so we can't be too far behind, haha."

"We can't compare this, Mr. Lu has solved two murder cases, but your Director Tian has won four cases, in terms of quantity, you have two more cases than Mr. Lu."

"It's all a small case, it's not worth mentioning, practice my hands today, and fight for a murder tomorrow."

Tian Rong's words are not bragging.

When he participated in the fingerprint battle before, he couldn't say that he solved the murder case every time, but it was no problem to be successful once every two years.

Tian Rong's highlight moment was six years ago, that is, the year he was transferred to the Technical Appraisal Center of the Provincial Department.

In the fingerprint battle that year, four murders were compared.

It has broken the record of a single battle than a homicide since the fingerprint battle in the province.

In that year, he won the first-class personal merit, and at the same time got the opportunity to transfer to the provincial department, and also received the expert allowance of the provincial department.

In terms of Fight to Fame, it is not an exaggeration at all.

In the conference room, all the experts who smoked a few cigarettes were alive again. Look at the book

All threw themselves into a new round of fighting.

I won't go to the cafeteria for dinner, Sun Bing asked everyone's opinions and directly asked the kitchen to deliver the food.

This will make the convention center taste a little wrong.

There is the smell of braised pork, the smell of sweaty feet of an unknown expert, and the smell of smoke left behind after smoking.

In the smell of chaos, more than a dozen experts were lying in front of the computer screen, their eyes blood-red.

Lu Chuan stopped typing on the keyboard anymore, and also lay on the computer screen, splitting the narrow original fingerprint into four parts.

Then one by one, it is broken down and enlarged, and finally put together.

Finally, more than four hours later, at nearly nine o'clock in the evening, the fingerprints were processed.

"I'll see how this time goes!"

Drag the fingerprint processed for the second time into the fingerprint comparison system.

It didn't take a few minutes for the sound of dinging to be heard.

Four large

The words appeared on the screen, reflected on Lu Chuan's tired face.
