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

Chapter 188
Thirteen years ago, an influential murder case occurred in Qianzhou City.

A high school student was robbed and killed in his home after extra classes at night.

The amount stolen was only 500 yuan.

The police found the killer's murder weapon at the scene of the crime, which was a fruit knife in the student's home.

A badly deformed blood print was found on the handle of a fruit knife.

However, the deformation of the fingerprint was too serious, and the technology at that time was limited, so it was not successfully identified in the first time.

After that, it entered the fingerprint battle library of the provincial department, and has been discovered by Lu Chuan until now.

Every time the provincial department organizes a fingerprint battle, in order to encourage more than a dozen experts to compete and catch up, a separate hero list is set up in the system.

Everyone's name is on it, and those who solve the case will accumulate corresponding points.

For example, a murder case, compared with one, accumulates ten points.

For other cases, according to the nature of the case and the degree of influence, there are scores ranging from three to eight.

According to the experience of previous fingerprint battles, on the first day everyone was looking for status and getting familiar with the environment, and generally there were few comparable cases.

It usually starts from the second day, and everyone gradually gains something.

The third day is the peak, and the fourth day is the peak. On the last day, everyone is basically exhausted, and the flags die down.

But this time, many people saw the Hero Ranking automatically pop up on the screen within a few minutes after turning on the computer.

After Lu Chuan's name, it's amazing!

What's the concept?
That's murder!

It's been less than an hour since the battle started, right?

Lu Chuan was involved in a murder case?
What is the backlog of homicide cases? It is a case that has been studied by many people, but it is still not solved in the end.

And those who can enter the fingerprint battle database of the provincial government are the most influential and vile cases.

Zhao Zhigao, who was sitting next to Lu Chuan, jumped up at this moment.

"Have you been murdered?"

Lu Chuan nodded, what's so strange about this, he chose the murder case.

"Good luck, this fingerprint is relatively simple."

Simple?
Zhao Zhigao almost rolled his eyes.

How can there be an easy case that can enter the fingerprint competition between the provincial government and the department?

Zhao Zhigao glanced at the screen, the robbery of high school students in Qianzhou City...

He knew about this case for more than ten years. He had studied this case when he participated in the fingerprint battle.

A blood fingerprint was squeezed so badly that it was impossible to analyze it.

"Fuck! How could it be him?"

The two were chatting when they were interrupted by a scream. They searched for the sound and found that it was a middle-aged criminal policeman with a Mediterranean haircut.

Zhao Zhigao has participated in many battles, and these dozen or so people all know each other: "Wang Huihui from the Ganzhou City Public Security Bureau and the Technology Appraisal Center has no official position, but he has good skills. The case you just won is theirs. of."

Just as he was explaining, Wang Huihui had already walked towards Lu Chuan.

"Mr. Lu, thank you. This case has been going on for more than ten years, and I never thought it would be solved one day."

Those who are masters are teachers, and most of the criminal police present here are technical men.

They are good at dealing with equipment, but most of them are not good at communication, and they like to speak directly.

In the case of Lu Chuanbi, it was Wang Hui who did the fingerprint identification and analysis back then.

It's just a pity that there was no suspect in the competition back then, and it was put in the fingerprint battle library of the provincial government. More than ten years have passed, and there is no result.

Now, finally see the light of day.

"You're welcome, but luckily, I may be more suitable for this kind of fingerprint."

There are many methods of fingerprint identification and analysis, and it is impossible for someone to be proficient in all techniques.

Therefore, some criminal police have a higher success rate when identifying dustpan fingerprints, and some have a higher success rate when dealing with bucket-shaped fingerprints.

There are also people who study single-fingerprint analysis methods, such as Liu Guodong, who is most familiar with the Qingdao-style single-fingerprint analysis method.

There are also people who are proficient in the analysis of finger prints, and some people focus on the analysis of palm prints.

Each has its own unique skills, and each person is good at different fields.

"Old Wang, what you said just now, the person in the competition is a bit unexpected?"

When Wang Huihui first saw the case, he didn't come to Lu Chuan immediately, but the people in the comparison were shocked.

Wang Hui nodded: "The person in the comparison... is the current husband of the deceased's mother."

Karma?
"His mother's husband?"

"Do you remember correctly?"

Wang Hui shook his head in affirmation: "I can't remember wrongly, I participated in this case back then, and I was very impressed."

"This student is studying well, and he will take the college entrance examination in half a year."

"The person who made the report back then was the uncle of the deceased..."

Wang Hui gave a general account of the case back then.

The parents of the deceased were divorced. Because the father was disabled, the son was awarded to the mother.

Later, the mother started a new family with her current husband.

"On the day of the incident, the deceased's mother worked overtime and asked the child's uncle to deliver food to the child, only to find that the deceased was dead."

"I didn't expect that it was his stepfather who killed the child..."

Now that the fingerprints are in the match, the rest is simple, follow the picture to find out, just arrest people directly.

Li Donglin left for less than an hour, and returned to the battle meeting room again.

He patted Lu Chuan on the shoulder again: "I knew you boy would not let me down!"

"Good good!"

After a short episode, the conference room became quiet again. The battle had just begun, and Lu Chuan used a murder case 13 years ago to get a good start, which really gave everyone a shot in the arm.

"Ding!"

Less than 10 minutes after Lu Chuan was awarded the murder case, another fingerprint was identified.

In front of everyone's computer screens, the automatically bouncing hero list unfolded.

No. 1 is still Lu Chuan, with ten points and one homicide case.

At this moment, No.2 appeared, Tian Rong, with five points and one robbery case.

"Teacher Tian, ​​congratulations!"

"Director Tian, ​​congratulations!"

Lu Chuan didn't know who Tian Rong was, and there were many people in the conference room congratulating him.

"It's not worth mentioning, good luck, hehe."

The person who spoke didn't get up. Lu Chuan stood up and looked. It was a middle-aged man sitting across from him.

The man seems to be very concerned about health preservation. There are goji berries and jujubes soaked in the water cup on the table.

Zhao Zhigao explained: "The expert from the Technical Appraisal Center of the Provincial Department is one of the most powerful people in fingerprint identification and analysis in our province."

Lu Chuan nodded, opened the case in the comparison, and saw the fingerprints in the comparison.

It's blurry, and the edges are full of burrs. Such fingerprints can be compared, which is really powerful.

After Lu Chuan sat down, he continued typing on the keyboard.

Lu Chuan was impressed by Tian Rong's ability to match such a difficult fingerprint.

Although I have advanced fingerprint identification and analysis skills, it doesn't mean that I am better than everyone else.

The Provincial Department does have experts, judging from the difficulty of identifying the fingerprint just now, this Tian Rong is not much worse than himself.

It seems that the level of advanced fingerprint identification and analysis is the level of top experts from the Ministry of Finance.

Lu Chuan is more motivated now, aiming at another murder case, continue!
