"Any other clues?" Wang Song shook his head: "Basically, there is no more, the crime scene is in the deep mountains and old forests, and the corpse has been gnawed by wild beasts, leaving no traces." ”

"If it weren't for a traveler who went into the mountain and accidentally found the body, no one would have been able to find it." Compared to death, disappearance is the most difficult case to deal with.

When you die, at least you know that people are dead. Missing, no one knows what happened to the person. The fingerprints extracted from Zheng Bin's field dagger are not just as simple as blurring.

After Lu Chuan magnified his fingerprint, he could obviously find that this was a composite fingerprint after the superposition of multiple layers of fingerprints. And there are traces of blood on it, as well as vaguely recognizable incomplete scratches.

"After using the dagger, the murderer should have wiped the fingerprints on the handle with something." Wang Song nodded: "Well, the experts of the provincial department said the same thing. ”

"But when I processed it again, I wasn't particularly careful, and I still left some residual scratch fingerprints." Such a fingerprint is, in Mandarin, a slippery hand.

Not only that, but after the murderer wiped the handle of the knife, he should have covered it with a layer of other fingerprints. No need to ask, the murderer must have re-handed the handle of the knife to Zheng Bin.

is worthy of being able to identify and analyze the fingerprints of the two successful murders, Wang Song nodded while listening: "That's it, what did the experts from the provincial department say." Lu Chuan nodded, he could see these details, and he could do it when Lu Chuan mastered the intermediate fingerprint identification and analysis skills.

However, if you want to identify and analyze fingerprints at that time, you will not be able to do it.

"Brother Wang, you wait a minute, it may take a little longer on my side." The processing of this fingerprint is obviously not something that can be completed in a while.

This is also the most difficult fingerprint to identify and analyze that Lu Chuan has encountered so far. In the end, whether the appraisal can be successful, Lu Chuan does not dare to guarantee.

The first is to digitize the fingerprint and complete the data stratification through two-dimensional transformation. Compared with the stacking of fingerprint lines seen by the naked eye, after the data is layered, the upper and lower layers of the fingerprint image will be easier to process.

On this side, it is easy to say, but it is troublesome to deal with. Lu Chuan had to manually filter the data, and it took more than an hour to complete this step.

In the conference room, the silence was a little scary. Except for the sound of Lu Chuan tapping on the keyboard, everyone else was breathless.

Although nine years have passed since the murder of Zheng Bin, there has been no conclusion. Was it because the case in Zheng Bin's hands was killed, or because he was killed by something in the mountains.

And because people are on vacation, death is not even a work-related death. Not to mention sacrifices and the like. Regardless of the identity of the police, this is a simple, leadless homicide.

Therefore, even back then, the investigation and handling of the case was not as strong as the power invested by Song Kun's murder. It's just that Zheng Bin's wife who was just pregnant was bitter.

And there are sons who have not been born and have no father. Over the years, Zheng Bin's wife has not remarried, and the Water District Criminal Police Brigade has arranged an auxiliary police job for internal service, which can be regarded as helping orphans and widows in disguise.

After the fingerprint is layered, it is the main thing. Because the fingerprints are scratched and wiped by the murderer, there are no fingerprint lines at the beginning and end of the front and back ends.

What Lu Chuan needs to do is to restore the multiple lines of friction into long lines into the shape of fingerprints. This afternoon, no one bothered Lu Chuan.

When Gao Wenxiang and others were smoking, the topic also revolved around Lu Chuan's fingerprints identified and analyzed: "Lao Sun, in our wave, you are the strongest, do you feel like there is any drama?" Sun Hao exhaled a puff of smoke: "I also read Zheng Bin's case back then." ”

"Just that fingerprint, don't talk about me, the experts from the provincial department have studied it for more than ten days, and they haven't done it."

"Lu Chuan......" The others also sighed. Obviously, although everyone knows that Lu Chuan is powerful, at least he is a lot better than everyone, and he can compare the two murder cases that have entered the fingerprint battle of the provincial department in a row, of course, it is powerful.

This shows that Lu Chuan has been able to reach the level of top experts in the provincial department in terms of fingerprint identification and analysis. However, even so, the experts of the provincial department did not get this fingerprint back then.

When everyone was smoking, Lu Chuan's pretreatment of fingerprints also entered the most critical time. Wang Song has been sitting beside Lu Chuan, watching with his own eyes and the whole process how Lu Chuan took out his fingerprints little by little.

Regarding Lu Chuan's operation, Wang Song basically has nothing that he can understand. If I had to describe it, I could only be unconscious.

"It's finally almost!" 4:28 p.m. After four hours of fighting, this blurred fingerprint finally turned into a one-third fingerprint with clear lines and normal lines in Lu Chuan's hands.

Next, as long as the feature points are marked and some data is calculated, it can be compared in the system.

A lot of hard work, the last wordy.

"Can it be done?" Wang Song looked even more nervous than Lu Chuan, and his forehead was soaked with fine beads of sweat. Lu Chuan smiled bitterly: "This fingerprint is too badly damaged, and the degree of deformation is so strong that the original fingerprint can no longer be seen." ”

"I used the method of probability analysis to find out the possibility of the most likely fingerprint extension, as for whether it can be successful...... No one can say. ”

"Let's put it in the system and run aside, why don't we smoke a cigarette." Wang Song watched Lu Chuan drag his fingerprints into the system comparison interface, and then got up and went to the smoking room outside the building with Lu Chuan.

At half-past four, it was already dark. But none of the criminal policemen who participated in the fingerprint battle left, and they all waited for the results of Lu Chuan's identification and analysis.

"Done?" In the smoking room, everyone was there, and Gao Wenxiang saw Lu Chuan and Wang Song coming out, so he asked first.

"Running in the system, smoking a cigarette." In fact, everyone really hopes that Lu Chuan will come out to smoke.

After all, the taste of China is indeed much better than that of red plums. Lu Chuan scattered cigarettes for everyone as usual, and lit one himself.

Although Lu Chuan has no addiction to smoking, as Lu Chuan's father said, cigarettes are the best social props between men.

With this, there is a common topic.

"How's the royal bureau going?" In the afternoon, Lu Chuan had been busy identifying and analyzing fingerprints, and he didn't bother to inquire about the two cases in the morning.

I asked casually.

"Haha, we just talked about that." Sun Miao leaned over: "Wang Ju has just come back, and the two cases you identified and analyzed in the morning have been caught. ”

"I heard that I didn't have much trial, and on the way back from the detention, I put the matter aside." Gao Wenxiang Xu felt more familiar with Lu Chuan than others because he sat next to Lu Chuan in the morning: "I just heard that the Song Bureau spoke, this fingerprint battle is over, and you will definitely be able to get a second-class merit!" "Second-class merit!

Hearing this, the expressions of the people who participated in the battle were different. Meritorious service, who doesn't want to do it.

Not only honor, but also money. However, it is not possible for ordinary people to solve two homicide cases at once.

As far as the Haizhou City Public Security Bureau's record in this fingerprint battle is concerned, not to mention the next six days, there will be two homicide cases, even if they are placed in the provincial department, it will be a major result.

And Lu Chuan, who solved the murder case quite single-handedly, is not high to give a second-class merit. Of course, the first-class work estimation is unlikely.

Unless, Lu Chuan got half of the thirteen murders, that's pretty much the same. Chatting and chatting, Wang Song took two puffs of Zhonghua, which was almost burning to the butt of the cigarette, and extinguished the cigarette butt in the column ashtray at hand: "You guys talk first, I'll go back and see the results." ”
