Thirteen years ago, there was a high-impact homicide case in Qianzhou City.

A high school student, after finishing a make-up class in the evening, was robbed and killed in his own home.

The amount of money that was robbed was only 500 yuan.

At the scene of the crime, the police found the murderer's murder weapon, which was a fruit knife in the student's house.

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

However, the fingerprint was too badly deformed, and the technology at the time was limited, so it was not successfully identified at the first time.

After that, he entered the fingerprint battle library of the provincial department, and until now, he was discovered by Lu Chuan.

Every time the provincial department organizes a fingerprint battle, in order to motivate more than a dozen experts to catch up with and surpass each other, 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 homicide, compared to a middle, accumulates ten points.

Other cases, depending on the nature of the case and the size of the impact, range from three to eight points.

According to the experience of previous fingerprint battles, on the first day, everyone was looking for a state and being familiar with the environment, and there were generally few cases that could be compared.

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

The third day is the peak, the fourth day is the peak, and on the last day, everyone who has survived is basically exhausted, and it will be gone.

But this time, many people even turned on the computer for a few minutes before they saw the hero list ranking automatically pop up on the screen.

After Lu Chuan's name, it is ten!

What is the concept of ten?

That's a homicide!

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

Lu Chuan was compared to a murder?

What is the backlog of homicide cases, which is a case that has been studied by many people, but in the end it is still unsolved.

And those who can enter the fingerprint meeting of the provincial department are even more influential and bad cases.

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

"You're more than a murder?"

Lu Chuan nodded, what's so strange about this, what he chose was a murder.

"Luckily, this fingerprint is relatively simple."

Simple?

Zhao Zhigao almost rolled his eyes.

How can the case of the fingerprint battle of the provincial department be simple?

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

He knows about this case, and he has studied this case for more than ten years, and he has studied this case when he participated in the fingerprint battle before.

A blood fingerprint, the squeeze is very serious, there is no way to analyze it.

"! How could it be him?"

The two were chatting when they were interrupted by an exclamation, and the two looked over and found that it was a middle-aged detective with a Mediterranean haircut.

Zhao Zhigao has participated in many battles, and these dozen people all know each other: "Wang Hui of the Qianzhou City Public Security Bureau and the Technical Appraisal Center, he has no official position, but his skills are good, and the case you just won is theirs."

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

"Mr. Lu, thank you, this case has been going on for more than ten years, but I didn't expect it to be solved one day."

The master is the teacher, and most of the criminal policemen present here are technical men.

I'm good at dealing with equipment, but most of them are not good at communicating, and they like to speak straight.

Lu Chuanbizhong's case was the fingerprint identification analysis done by Wang Hui back then.

It's just a pity that there was no suspect in the comparison back then, and he was put in the fingerprint battle library of the provincial department, and more than ten years have passed, and there is no result.

Now, at last, we have seen the light of day.

"You're welcome, it's just luck, I might be more suitable for this kind of fingerprinting."

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

Therefore, some criminal police officers 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 delve into the single-finger fingerprint analysis method, such as Liu Guodong, who is most familiar with the Qingdao-style single-finger fingerprint analysis method.

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

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

"Lao Wang, what you just heard from you was a little unexpected than the person in the middle?"

When Wang Youyou just saw the case, he didn't come to Lu Chuan for the first time, but was shocked by the people in the comparison.

Wang Hui nodded a little: "The person in the middle of the competition...... is the current husband of the deceased's mother."

Karma?

"His mother's husband?"

"Remember correctly, right?"

Wang Youyou shook his head affirmatively: "I can't be mistaken, I was involved in this case back then, and I was very impressed."

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

"The informant was the deceased's uncle......

Wang Hui roughly recounted the facts of the case that year.

The deceased's parents divorced because the father had a disability and the son was awarded to the mother.

Later, my mother started a new family and had her current husband.

"On the day of the incident, the mother of the deceased worked overtime to ask her uncle to bring food to the child, and found that the person was dead."

"Unexpectedly, it was his stepfather who killed the child......

Since the fingerprint is matched, the rest is simple, just follow the map and arrest people directly.

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

He patted Lu Chuan on the shoulder heavily: "I knew that you kid would definitely not let me down!"

"Good, good!"

After a short interlude, the conference room was quiet again, this battle had just begun, and Lu Chuan had made a good start with a murder case thirteen years ago, which really gave everyone a shot in the arm.

"Ding!"

It was less than 20 minutes before Lu Chuan's murder, and someone compared his fingerprints.

In front of everyone's computer screens, the list of heroes that automatically bounce unfolds.

The first place is still Lu Chuan, with ten points, and there is one more homicide case than the middle case.

At this moment, the second place, Tian Rong, has five points, and he has one robbery.

"Teacher Tian, congratulations!"

"Director Tian, congratulations!"

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

"It's not enough to worry about it, good luck, hehe."

The person who spoke didn't get up, Lu Chuan stood up and looked, it was a middle-aged man sitting opposite.

The man seems to be very health-conscious, and the water cup on the table is soaked with wolfberries and jujubes.

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

Lu Chuan nodded, clicked on the case of the other party's comparison, and saw the fingerprints of the opponent's comparison.

Blurred, the edges are full of burrs, such a fingerprint can be compared to the middle, it is really powerful.

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

Tian Rong's fingerprints that were so difficult to compare made Lu Chuan impressed.

Although he has advanced fingerprint identification and analysis skills, he is not better than everyone else.

The provincial department does have masters, judging from the difficulty of the identification of the fingerprint just now, this Tian Rong is not much worse than himself.

It seems that the level of advanced fingerprint identification analysis is the level of top experts in the provincial department.

Lu Chuan is now more motivated, aim for another murder, and continue!
