Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 139
It took Lu Chuan a little longer to process the bloody fingerprints.

It took more than an hour to restore the original fingerprint, but the texture is still not clear, and it is still difficult to mark the feature points.

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

And after this bucket was operated, the people behind Lu Chuan had long been dumbfounded.

It wasn't until the sound of a successful fingerprint comparison sound specially prepared for the fingerprint battle that everyone came back to their senses.

Another hit!

Moreover, it was another murder case!
Sun Miao, who just smoked with Lu Chuan outside the building, is a criminal policeman from the Criminal Police Brigade of the High Speed ​​Rail New Area.

Originally, Sun Miao was a first-line criminal policeman, but because she was talented in fingerprint identification and analysis, she concurrently served as the current survey and fingerprint identification criminal policeman of the criminal police brigade.

Four years ago, an extremely vile case of burglary occurred in the high-speed rail new area.

The head of the household was an old man who lived alone, and was hacked to death by the murderer with a kitchen knife from the deceased's home.

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

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

While excited, 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 database of the provincial department in the second year after the incident, and no one could match it twice in a row.

Sun Miao didn't know how many fingerprint identification and analysis masters there were in the province, but the provincial departments must have organized elite experts.

Haizhou Public Security Bureau sent out in previous years, can only take No. 1 in the bottom of the tie.

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, if you don't have to do it, it will be for nothing.

Because it doesn't work at all.

In the end, Lu Chuan won the competition in less than two hours?

Before this case of burglary and death occurred that year, there were many burglaries in succession within the jurisdiction of the Criminal Police Brigade of the High-speed Railway New Area.

Moreover, the method of breaking the door is similar. After research and judgment, it is believed that the murderer of the burglary and murder should be the murderer of the several burglaries.

The so-called burglary, and burglary, the key point is not the murderer.

It's about whether there is anyone at home.

No one, called burglary, someone, called burglary.

Of course, there are also special circumstances, such as someone at home but fell asleep, and there is no confrontation with the thief, which is also burglary.

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

"Let me see! Let me see!"

Compared with others, Sun Miao looked forward to knowing who the murderer was.

On the screen, behind a few bright red characters, is the identification and analysis report.

"Hu Yong?"

Sun Miao's voice raised an octave!

"This is impossible!"

Lu Chuan twisted his stiff neck and turned to look at Sun Miao.

Well, those from the High Speed ​​Rail New Area must be familiar with this case.

"This Hu Yong...is at it again?"

Sun Miao woke up and explained to Lu Chuan: "Hu Yong was the deceased's neighbor and the reporter at that time!"

Reporter...

That's a thief calling catch a thief.

Before comparing the fingerprints, Lu Chuan did not read the case files carefully, but only studied the fingerprints.

So I don't know the investigators at that time, and the murderer was locked on the mobile criminals.

There was a deviation in the direction, no wonder the case could not be solved and the suspect could not be caught.

A lot can be done in two hours.

No. 72 Cuiping Road, Sunshine Happy Low-rent Housing Community.

Building two, three units, room 1008.

A large group of heavily armed criminal policemen was escorting a middle-aged man wearing only shorts.

The man looked astonished, and was pinned down to put it on.

"What is your name?"

"Li Zhi."

"Do you know why I arrested you?"

Li Zhi, who was being detained, looked pale.

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

"Yeah, what are you doing! Why are you arresting my old man?"

Li Zhi's wife looked at the many policemen in horror, not knowing what her husband had done and so many people came.

"Didn't break the law? Hmph! Seven years ago, did you forget about the cultural park?"

culture Park?

Li Zhi's face became even paler, and some of his strength of resistance also suddenly declined.

"You guys...we still found it..."

Li Zhi was a cleaner in the cultural park area back then, but when the incident happened, he was not at work but at the time.

But even so, Li Zhi was also the focus of the investigation that year.

However, because of the only evidence, the half of the fingerprints could not be successfully compared, so the suspect could not be identified.

The reason why Li Zhi finally escaped from the investigation was because his wife testified that Li Zhi was at home when the crime happened.

It now appears that Li Zhi's wife clearly gave false testimony.

Giving false testimony to cover 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 [-] households in one unit.

Most of the people who moved here with Li Zhi were cleaners or neighbors from the past.

Compared with ordinary commercial and residential buildings, the neighbor relationship in low-rent housing is closer.

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

"Did Mr. Li commit a crime?"

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

"Murder? Old Li? Don't talk about it. Old Li is famously honest. He dare not kill a chicken, but still kill?"

A person cannot be judged by his appearance, and sea water cannot be measured.

On the car back to the bureau, Zhang Guiqin explained everything.

"My son is going to college... There is nothing I can do. Old Li didn't kill her on purpose, really... woo woo... We didn't do it on purpose..."

Wang Kai sighed deeply.

Looking at Zhang Guiqin and Li Zhi: "You can rob others and kill others just because your own children go to school?"

"Then do you know that the person you killed was just one month pregnant!"

No one has the right to take another's life for any reason.

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

The lack of money that Zhang Guiqin mentioned was not for her son's tuition.

Back then, the most popular love crazy mobile phone.

When it was first sold, a mobile phone cost tens of thousands of yuan.

Li Zhi's son wanted an icrazy mobile phone, saying that without this mobile phone, he would be looked down upon even when he went to university.

Only then has the follow-up.

"You guys...wait for the punishment of the law!"

In this case, it was precisely because of the special circumstances of the deceased that Wang Kai had been watching him personally.

As long as there is an opportunity, take this case out and study it.

At that time, the investigation of the case was very detailed.

The fact that the deceased was pregnant was discovered during the forensic autopsy.

Neither the deceased nor the family members of the deceased knew.

Otherwise, when the deceased is killed, it will be more painful.

Letting out a long breath, Wang Kai leaned back in the chair a little tiredly.

The simple inquiry just now seemed to take all the strength out of Wang Kai's body.

As a police officer, you will inevitably come into contact with various dark sides of society.

The criminal motives of some suspects are simply incomprehensible.

For example, Li Zhi's motive for robbery and murder was just to buy a mobile phone for his son!
a cell phone!
One corpse, two lives!
He... damn it!
Ding!
The text message alert sounded, and Wang Kai subconsciously took out his phone.

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