For the processing of blood-colored fingerprints, Lu Chuan took a little longer. For more than an hour, the original fingerprint was restored, but the texture was still not clear, and it was still difficult to mark the feature points.

After that, Lu Chuan successively used the gradient method, operator, high-pass filtering, mask matching method, statistical difference method, etc., to enhance the image, and finally obtained the fingerprint that can be annotated with feature points.

And after this bucket is operated, the people behind Lu Chuan have long been stupid. It wasn't until the fingerprint battle, which was specially prepared for the fingerprint battle, that the fingerprint comparison success prompt sounded, and everyone came back to their senses.

Again! And, another homicide! Sun Miao, who had just smoked outside the building with Lu Chuan, was a criminal police officer of the Criminal Police Brigade of the High-speed Rail New Area.

Originally, Sun Miao was a front-line criminal policeman, and because he was talented in fingerprint identification and analysis, he concurrently served as the criminal police officer of the criminal police brigade for on-site investigation and fingerprint identification.

Four years ago, there was an extremely egregious burglary in the new high-speed rail area. The head of the household, an elderly man who lived alone, was hacked to death by the murderer with a kitchen knife in the kitchen of the deceased's house.

At that time, the scene of the crime was investigated by Sun Miao, and the only blood fingerprint was also collected by Sun Miao.

Therefore, Sun Miao was very excited when he saw that Lu Chuan had chosen a case in their jurisdiction.

At the same time, he also knew how difficult it was to identify and analyze this blood fingerprint. Not to mention him, this blood fingerprint entered the fingerprint battle library of the provincial department in the second year after the case, and twice in a row, no one could compare.

Sun Miao doesn't know how many fingerprint identification and analysis masters there are in the province, but the provincial department organization must be an expert elite.

Those sent out by the Haizhou City Public Security Bureau in previous years could only take the tied first place. And Liu Guodong's level is already the ceiling in Sun Miao's eyes.

However, when Liu Guodong faced this fingerprint, he didn't even try to analyze it. In his words, you don't have to do it, and if you do it, it's for nothing.

Because it can't be done at all. As a result, Lu Chuan won in less than two hours? Before the case of the death of the burglary, there were many burglaries within the jurisdiction of the Criminal Police Brigade of the High-speed Rail New Area.

And the method of breaking the door is similar, and after research and judgment, it is believed that the murderer of the burglary should be the murderer of those burglaries.

The so-called burglary, and burglary, the key point is not the murderer. It's about whether there is anyone in the family.

Nobody, called burglary, and somebody, called burglary. Of course, there are special circumstances, such as someone in the house but falling asleep and not having a head-on confrontation with the thief, which is also burglary.

Pulling away from the colleagues who were blocking in front, Sun Miao struggled behind Lu Chuan.

"I'll see! Let me see! Compared with others, Sun Miao is more looking forward to knowing who the murderer is. On the screen, behind a few bright red letters, it is the identification analysis report.

"Hu Yong?" Sun Miao's voice raised an octave!

"It can't be!" Lu Chuan twisted his somewhat stiff neck and turned his head to look at Sun Miao. Well, the high-speed rail new area must be familiar with this case.

"This Hu Yong...... Again? Sun Miao came to her senses and explained to Lu Chuan: "Hu Yong is the neighbor of the deceased and the informant at that time!" "The informant...... That's the thief shouting to catch the thief.

Before comparing fingerprints, Lu Chuan did not look at the case file carefully, but only studied the fingerprints. Therefore, I don't know much about the case-handling personnel at that time, and locked the murderer on the rogue criminals.

There has been a deviation in the direction, no wonder the case cannot be solved, and the suspect cannot be caught. In two hours, a lot can be accomplished.

No. 72, Cuiping Road, Sunshine Happiness Low-rent Housing Community. Two buildings with three units, room 1008. A large number of heavily armed criminal police officers are escorting a middle-aged man wearing only shorts at the moment.

The man looked stunned and was pressed on his stomach to put it on.

"What's your name?"

"Li Zhi."

"Do you know why I arrested you?" Li Zhi, who was being escorted, turned pale.

"I don't know, I didn't break the law, I'm just a cleaner."

"yes, what are you doing! What are you doing with my old man? Li Zhi's wife looked at the many policemen in horror, not knowing what her husband had done, so many people came.

"Didn't break the law? Hum! Seven years ago, you forgot about the Cultural Park? "A cultural park? Li Zhi's face became even paler, and some of his strength to resist also declined abruptly.

"Gentlemen...... I still found ......" Li Zhi, who was the cleaner in the Cultural Park area back then, but it was not his time to go to work when the crime occurred.

But even so, Li Zhi was also the focus of investigation that year. However, because of the only evidence, the half of the fingerprints can never be successfully compared, and the suspect cannot be locked.

And the reason why Li Zhi finally escaped from the investigation was that his wife corroborated that Li Zhi was at home at the time of the crime.

Now it seems that Li Zhi's wife apparently gave false testimony. gave false testimony and covered up the crime: "Take Zhang Guiqin away together." "Zhang Guiqin, Li Zhi's wife.

Sunshine Happy Community is a low-rent housing community that was just built and put into use five years ago. In order to accommodate more people, the building is designed as a tube building, with more than 20 families in one unit.

Most of the people who moved in with Li Zhi were cleaners or neighbors back then. Compared with ordinary commercial and residential buildings, the neighborhood relationship in low-rent housing is closer.

At this moment, the doors of basically every house are open, and dozens of people are watching.

"Lao Li Tou has committed an accident?"

"I don't know, it seems to be a murder case!"

"Murder? Old Li Tou? Don't talk nonsense, Lao Li is notoriously honest, he doesn't dare to kill chickens, and he still kills people? "Let no man look like a man, and let the sea not weigh it.

Returning to the car in the bureau, Zhang Guiqin explained everything.

"My son goes to college...... There's really no way, Lao Li didn't kill her on purpose, really...... Woowoo...... We didn't mean to......" Wang Kai sighed deeply.

looked at Zhang Guiqin and Li Zhi: "For the sake of your children's schooling, you can rob others and then kill people?" ”

"Do you know that the person you killed was just a month pregnant!" No one has the right to deprive another person of his or her life for any reason.

The current student aid system is very sound, and Li Zhi's children can apply for student loans when they go to university, and there is no problem in completing their studies.

And the lack of money that Zhang Guiqin said was not for her son's tuition. Back then, the most popular crazy mobile phone.

When it first started selling, a mobile phone cost tens of thousands. Li Zhi's son wanted a crazy mobile phone, saying that without this mobile phone, he would be looked down upon when he went to college.

That's the follow-up.

"You ...... Wait for the law! "In this case, it is precisely because of the special circumstances of the deceased that Wang Kai has been watching it personally.

As long as there is an opportunity, take out this case and study it. At that time, the investigation of the case was very meticulous.

The circumstances of the deceased's pregnancy were discovered during a forensic autopsy. The deceased himself and the deceased's family did not know.

Otherwise, it will be even more painful when the deceased is killed. With a long exhale, Wang Kai leaned back in the chair a little tiredly.

The simple question just now seemed to drain Wang Kai's whole body. As a police officer, you will inevitably come into contact with all kinds of dark sides of society.

There are even some suspects whose motives for committing crimes are simply incomprehensible. For example, Li Zhi's motive for robbery and murder was just to buy a mobile phone for his son!

A mobile phone! One corpse, two lives! He...... Damn it! Bite! The mobile phone text message prompt sounded, and Wang Kai subconsciously took out his mobile phone.

It doesn't matter if you look at it, Wang Kai's spirit that has just relaxed is tense again!
