Thirteen years ago, an influential murder case occurred in Qianzhou City.
A high school student was robbed and killed in his home after taking extra classes in the evening.
The amount robbed was only five hundred yuan.
The police found the murder weapon at the crime scene, which was a fruit knife from the student's home.
A severely deformed bloody fingerprint was found on the handle of the fruit knife.
However, the fingerprint was too severely 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 until he was discovered by Lu Chuan.
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 names are on it, and those who solve the case will accumulate corresponding points.
For example, if you win a murder case together, you will accumulate ten points. .
Other cases, depending on the nature of the case and the degree of influence, have scores ranging from three to eight.
According to the experience of previous fingerprint battles, on the first day everyone is looking for status and getting familiar with the environment, and there are generally few cases that can match it.
Usually starting from the second day, everyone gradually gains something.
The third day was the peak, the fourth day was the peak, and on the last day, everyone was basically exhausted and stopped.
But this time, many people saw the hero list automatically popping up on the screen within a few minutes of turning on the computer.
After Lu Chuan's name, there was an impressive number!
What is the concept of ten?
That's a murder!
It's only been less than an hour since the war started, right?
Lu Chuan was involved in a murder case?
What is the backlog of murder cases? They are cases that have been studied by many people, but still have not been solved in the end.
And the cases that can enter the fingerprint database of the provincial department are the most influential and egregious cases.
Zhao Zhigao, who was sitting next to Lu Chuan, had jumped up at this moment.
"Have you been hit by a murder case?"
Lu Chuan nodded. What's weird about this? He chose the murder case.
"Luckily, this fingerprint is relatively simple."
Simple?
Zhao Zhigao almost rolled his eyes.
How can a case that can enter the provincial department’s fingerprint trial be simple?
Zhao Zhigao glanced at the screen, the robbery case of high school students in Qianzhou City...
He knew about this case for more than ten years. He had studied this case before when he participated in the fingerprint battle.
A bloody fingerprint was so severely squeezed 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 looked over and found a middle-aged detective with Mediterranean hair.
Zhao Zhigao has participated in many battles, and he all knows these dozen people: "Wang Youyou from the Qianzhou City Public Security Bureau and the Technical Appraisal Center doesn't have any official position, he just has good skills. The case you just won is one of theirs." of."
While he was explaining, Wang Youyou had already walked towards Lu Chuan.
"Teacher Lu, thank you. This case has been going on for more than ten years. I never thought that it would be solved one day."
A master is a teacher, and most of the detectives here are skilled men.
They are good at dealing with equipment, but most of them are not sociable and like to speak directly.
The case in which Lu Chuan was selected was the result of fingerprint identification and analysis conducted by Wang Youhui.
It's just a pity that there was no suspect in the match at that time, so he was placed in the provincial department's fingerprint database. More than ten years later, there was no result.
Now, it finally sees the light of day.
"You're welcome. I'm just lucky. I might be more suitable for doing this kind of fingerprints."
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, while others have a higher success rate when dealing with bucket-shaped fingerprints.
There are also people who study single-finger fingerprint analysis methods, 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 finger print analysis, and even more people focus on analyzing palm prints.
Everyone has their own unique skills, and everyone is good at different areas.
"Old Wang, what you just said was that the person who won the competition was a bit unexpected?"
When Wang Youhui first saw the case, he did not come to Lu Chuan immediately, but the people in the comparison were shocked.
Wang Hui nodded slightly: "The winning person... is the current husband of the deceased's mother."
Karma?
"His mother's husband?"
"You remember correctly?"
Wang Youhui shook his head affirmatively: "I remember correctly, I participated in this case back then and it left a deep impression on me."
"This student is studying well and will take the college entrance examination in half a year."
"The person who reported the crime was the uncle of the deceased..."
Wang Hui gave a rough account of the case that year.
The deceased's parents divorced, and because his father was disabled, the son was awarded to his mother.
Later, my mother started a new family and got 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 child was dead."
"I didn't expect that it was his stepfather who killed the child..."
Now that the fingerprint comparison is successful, the rest is simple. Just follow the picture and arrest the person directly.
Li Donglin left for less than an hour and returned to the battle conference room again.
He patted Lu Chuan's shoulder heavily: "I knew you wouldn't let me down!"
"Okay, okay!"
After a brief interlude, the conference room fell silent again. The battle had just begun when Lu Chuan got off to a good start with a murder case from thirteen years ago, which really gave everyone a shot in the arm.
"Ding!"
Less than twenty minutes after Lu Chuan's murder, someone else's fingerprints were matched.
In front of everyone's computer screen, a hero list automatically popped up.
Ranking first is still Lu Chuan, with ten points and one murder case in the backlog.
At this moment, the second place 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 yet, but many people in the conference room congratulated him.
"Not worth mentioning, good luck, haha."
The person who spoke did not stand up. Lu Chuan stood up and took a look. It was a middle-aged man sitting opposite.
The man seems to pay great attention to health. There are wolfberry and jujube soaked in the water glass on the table.
Zhao Zhigao explained: "An expert from the Provincial Technical Identification Center is one of the most powerful people in fingerprint identification and analysis in our province."
Lu Chuan nodded, clicked on the case that the other party had won, and saw the fingerprints that the other party had won.
It's blurry and the edges are full of burrs. It's really impressive that such a fingerprint can compare to the center.
After Lu Chuan sat down, he continued to type on the keyboard.
Lu Chuan was impressed by Tian Rong's ability to win such a difficult fingerprint.
Although he has advanced fingerprint identification and analysis skills, it does not mean he is 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 analysis is that of top experts from the provincial department.
Lu Chuan is now more motivated to target another murder case and continue!
