Processing a fingerprint is like performing a surgical operation.
Accurately identifying the lesion is only the first step, and requires superb surgical skills.
Peeling off the cocoon is like sewing up a wound, stitch by stitch, without any carelessness.
As expected, Lu Chuan did not get a complete fingerprint after processing the fingerprint.
It's less than 20% of the size of a normal fingerprint, less than one-fifth, but more than one-tenth.
It starts from the center of the fingerprint and spreads outward, becoming blurry toward the edges.
This is much better than Lu Chuan initially expected.
But it still has not reached the ideal state. If it can exceed 20%, then Lu Chuan will be sure to mark enough characteristic points, so that the fingerprints analyzed will have judicial effect.
Now, with the current size of this fingerprint, Lu Chuan can only mark nine feature points.
Although the number is large, it cannot be used as evidence to identify the suspect.
However, that doesn't mean it's useless.
Lu Chuan could still use this incomplete fingerprint to compare the suspect's identity in the fingerprint comparison system.
Then, through investigation and interrogation, we can determine whether the other party is the murderer and supplement the evidence.
Dragging the fingerprint into the fingerprint database, Lu Chuan waited expectantly for the result.
Ding!
The system comparison results dialog box pops up.
"Comparison failed!"
fail?
Lu Chuan frowned slightly.
Is there no target sample in the system at all, or is there something wrong with the fingerprints I preprocessed?
It is not difficult to verify this issue.
As long as Lu Chuan uses another method to preprocess the fingerprints, and then compares it with the original preprocessing 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, there was something wrong with Lu Chuan's handling.
I looked at the time and saw that the afternoon had almost passed.
At this time, the experts quickly entered the state because Lu Chuan had matched the fingerprints of two murder cases.
Many people have achieved results one after another.
Director Tian Rong of the Provincial Technical Appraisal Center has even won four cases.
Although there is no backlog of murder cases, it can still be considered a major case. In terms of accumulated points, it has reached 18 points.
It was only two points away from Lu Chuan's total score of twenty points.
Two points, which is a robbery or intentional assault case.
With Tian Rong's strength, if Lu Chuan doesn't gain anything next, he will be able to catch up tomorrow.
Even if you work overtime today, you may exceed it.
After Tian Rong, someone won two cases and ranked third.
The rest were successful in one case, and more often were not successful in any case.
Zhao Zhigao, who was sitting next to Lu Chuan, had completed a fingerprint at this moment. Without exception, he failed.
"Let's go, smoke one, be refreshed, come back and fight again!"
Lu Chuan looked at it and saw that many people had gone out to get some fresh air. He responded and followed them out.
"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 Yuan Chao has mentioned you to me more than once, saying that you are very good at skeletal 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 a director.
In the provincial department, there is 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, thank you. You just have better luck."
Lu Chuan responded politely, took the initiative to hand over a Huazi, and then gave one to several people around him.
Gradually, everyone gathered around
.
On the one hand, Tian Rong has the highest technical level among all experts, and he is also an expert at the Provincial Technical Appraisal Center.
He was originally a central figure, and when he came out to smoke, he was the core of everyone's chat.
After Lu Chuan came out, with his impressive record of killing two murders in one day, he must be a famous figure among this group of people.
"Haha, you are not lucky enough to be able to enter the provincial fingerprint competition for murder fingerprints. How can it be easy?"
Tian Rong took the cigarette and others agreed.
"That's right, in the case of the high school student, I saw the fingerprints the year before last, but after two days of working on it, I didn't have any clue."
"Teacher Lu, don't be modest. You are young and you are promising. You are young and you are promising."
"By the way, Brother Zhao, how's it going in Tianzhou City?"
While chatting, Wang Youyou came over and said, "The taxi serial murder case started more than ten years ago, right?"
"In the provincial department's fingerprint database, this case seems to have been pending for more than ten years. Has anyone been caught?"
Zhao Zhigao nodded heavily and blew out the last puff of smoke.
"We caught him. He is in Tianzhou City. After Teacher Lu's identification and analysis report was passed on, the detachment carried out the arrest."
"He can't run away. Even if he doesn't confess in other cases, he can't run away in the case where the fingerprints were left."
Several experts chatting together nodded. They had also heard about the serial murders of taxi drivers in Tianzhou City.
There were even several people who had studied the fingerprints from that year's case, but they had gained nothing.
But everyone also knows that this kind of case takes too long and is not easy to solve, especially since the murderer left no clues at the scenes of other crimes.
If the other party refuses to admit it, it will really be difficult to handle.
"Okay, the boat will straighten out when it reaches the bridge, so we have to work harder!"
Tian Rong obviously also knows the ins and outs of this case.
"Teacher Xiao Lu has solved two murder cases, we can't be too far behind, haha."
"We can't compare. Teacher Lu has solved two murder cases, but you, Director Tian, have solved four cases. In terms of quantity, you have two more cases than Teacher Lu."
"My cases are all small, not worth mentioning. Let's practice today and try to attack the murder case tomorrow."
Tian Rong's words were not bragging.
When he participated in the fingerprint competition before, he could not say that he could solve the murder case every time, but it was no problem to solve the murder case once every two years.
Tian Rong’s highlight moment was six years ago, the year he was transferred to the provincial technical appraisal center.
In the fingerprint battle that year, four murders were detected.
It broke the record of more homicides in a single battle since the province began to have fingerprint battles.
That year, I won the first-class personal merit, and also got the opportunity to be transferred to the provincial department, and also received the expert allowance from the provincial department.
To say he became famous in one battle is no exaggeration at all.
In the conference room, all the experts who had smoked a few cigarettes became lively again. Read the book
Everyone has entered a new round of fighting.
He won't go to the canteen for dinner. Sun Bing asked everyone for their opinions and asked the kitchen to deliver the food directly.
Now, the smell of the conference center is a bit off.
There is the smell of braised pork, the sweaty feet of some unknown expert, and the smell of smoke left behind after smoking.
Amid the messy smell, a dozen experts were lying in front of the computer screen, their eyes bloodshot.
Lu Chuan stopped typing on the keyboard. He also leaned on the computer screen and divided the narrow original fingerprint into four parts.
Then break it down and enlarge it piece by piece, and finally put it together.
Finally, more than four hours later, at nearly nine o'clock in the evening, the fingerprints were processed.
"Let's see how it goes this time!"
Drag the fingerprint processed for the second time into the fingerprint comparison system.
Within a few minutes, a dinging sound came.
four big
The words appeared on the screen, reflecting on Lu Chuan's tired face.
