The canteen of the City Bureau has always been very quiet. Even when eating, there is only the sound of chewing vegetables, and even the sound of drinking soup is rarely heard.
But today is different. In a corner of the canteen, there are more than a dozen people, surrounding two tables, making loud noises.
"Teacher Lu, you are really amazing! How did you win the match with that blood fingerprint?" Unlike ordinary laymen, being able to participate in the fingerprint competition held by the city bureau is enough to show that everyone at the dinner table is very good at fingerprint identification and analysis. There are two brushes.
It was precisely because of the two brushes that they knew how difficult it was for Lu Chuan to successfully identify and analyze the two fingerprints.
Everyone who watched Lu Chuan's preprocessing of blood fingerprints was very suspicious of whether Lu Chuan was an investigation detective or a detective detective.
The number of detective detectives has been gradually expanding in recent years. Compared with traditional criminal police such as forensic medicine and field investigation, the demand is growing.
This is mainly because when solving crimes nowadays, there is often no need for investigation and just finding the surveillance video, which is equivalent to catching the crime.
Therefore, when investigating a case now, everyone's first reaction is to look for surveillance cameras near the crime scene.
If there is no such direct evidence, we will look for other clues. As a result, every district and county criminal police brigade now has a dedicated picture investigation squadron.
Although there may not necessarily be a few people, this can be regarded as a specialized position establishment. In Gao Wenxiang's impression, Lu Chuan had just been processing fingerprint images on the computer, which seemed like he was trying to solve a case.
The difference is that Lu Chuan's method of analyzing images looks high-end and classy to them. The picture detectives in my criminal police brigade can only scan videos.
Fast forward, rewind and pause, and occasionally two experts will remove noise points. A person like Lu Chuan, with data streaming all over the screen... has never been seen in movies.
"That's right, this time Teacher Lu solved two murder cases in a row. Our fingerprint battle has achieved great results!" Sun Hao's attitude was also very low.
Lu Chuan was able to solve the backlog of murder cases, and Sun Hao knew that the process of processing fingerprints was a technique that even provincial and department experts might not master.
There are also differences in the frogs who sit in the well and look at the sky. Some can only see a patch of sky as big as a palm, and some can see two patches of sky as big as a palm.
Sun Hao is obviously the latter. Lu Chuan was also in a good mood, not because of the compliments from his colleagues, but because he had really solved the case and was in a high mood.
As a criminal police officer, no matter what position you are in, no one wants to solve more cases. As the deputy director, Wang Kai can't take care of eating now and is busy arresting people outside?
Of course, this arrest was definitely a happy one. Seven years of backlog, four years of backlog! Lu Chuan's second-class merit did not go away, and neither did Wang Kai's achievements.
You know, fingerprint battles are something he is in charge of. It is not common to achieve such great results in fingerprint battles of provincial departments.
After all, any of the backlog of murder cases that have not been reviewed by experts for several rounds and remain unsolved until now cannot be solved by ordinary means.
Being able to work in the city bureau requires not only your ability, but also your vision. Many gentlemen looked at the group of blue shirts laughing and chatting in the corner and knew what was going on.
Two murder cases... shocking. A meal only takes half an hour. Normally, everyone would take a break at noon.
The fingerprint battle competes with eyesight and consumes energy, although in most cases there is no result.
But there is no such thing as a foreigner. Everyone represents their own criminal police brigade to participate in the battle. If you have achieved results, you will have glory when you return to the team.
The Haizhou City Public Security Bureau says it's big, and it's indeed quite big. There are thousands of police officers from all police types combined. But to say small, it is also very small. After all, there are only a few people doing fingerprints.
Everyone wants to have some status in this circle, so every fingerprint battle in the city bureau, although the results are average, is quite complicated.
The bigger the volume, the more energy is consumed. Taking a break at noon does not take up much time, but it is very beneficial to the work in the afternoon and evening.
But this time, Lu Chuan didn't rest, and neither did everyone. Anyway, they didn't do much work in the morning, so everyone was in good spirits.
Moreover, there are still eleven murder cases in the case library of this fingerprint battle. Everyone wanted Lu Chuan to work on his own unit's case first.
As a result, a large number of criminal police officers who used the city bureau conference room to conduct a surprise attack, under the watchful eyes of the local police working in the city bureau, left like the real owners.
"Teacher Lu, I am Wang Song from the Water District Criminal Police Brigade." Lu Chuan nodded. He just heard Gao Wenxiang tell us about everyone's situation. This Wang Song is the oldest criminal policeman participating in the fingerprint battle.
I am 57 years old today and have three years to retire. At this age, Lu Chuan admires him for working so hard.
"Hello, Brother Wang." Lu Chuan, who was not very familiar with the Water District Criminal Police Brigade, greeted him and handed him a piece of Huazi: "I'm not a teacher. Just call me Xiao Lu or Lu Chuan. Come on, boss. Brother, smoke one." Wang Song took the cigarette, but instead of smoking, he talked about the case: "Then I'll ask you to call you Xiao Lu." Most criminal police officers are not very good at intrigues.
Therefore, Wang Song simply believed what Lu Chuan said.
"The main thing is to ask you to help me with a case."
"Are you participating in this fingerprint battle with Curry?" Wang Song nodded: "Yes, it was also a murder case. The person who died was a criminal policeman from our brigade." Death?
Whenever a police officer dies, it is a major crime. For example, in the case of Song Kun's murder, although Chen Gang faked the scene of the car accident, he was not discovered in the end.
However, death and sacrifice are not the same concept.
"When did it happen?" Lu Chuan had never heard of the death of detective Shui District. That must not have happened after he joined the police, or even in the past one or two years. Otherwise, there would always be rumors.
Of course, if it is an ordinary death or killing, the scope of the impact will be smaller.
"Nine years ago." Speaking of this, Wang Song's expression was a little heavy: "He did not die during the mission, he was killed while on vacation."
"Killed on vacation?" Wang Song nodded: "Nine years ago, in Miaowang Mountain, the body was almost eaten by wild animals when it was found."
"During the on-site investigation, we found the murder weapon nearby, and that's when we determined that he was killed." Wang Song roughly told the story of the case, but in fact there wasn't much valuable information.
The detective who was killed was named Zheng Bin, and he was only 32 years old when he died. Zheng Bin likes mountain climbing, hiking and wild camping. When he has time off every year, he goes into the mountains to explore.
Nine years ago in June, the Water District Criminal Police Brigade received a call from a traveler. Only then did they realize that the person who died was a member of their criminal police brigade.
In front of the computer, Lu Chuan was preprocessing fingerprints. The murder weapon at that time was inspected and confirmed to be a field dagger brought by Zheng Bin himself.
In addition to his fingerprints, a strange fingerprint was also collected on it. Although it cannot be determined that the owner of this fingerprint is the murderer himself, the fact that it appears on Zheng Bin's field dagger must be related to Zheng Bin's death.
The clarity of the fingerprint is very poor and the whole thing is blurry. Moreover, due to the force of squeezing, the ridges are stacked and squeezed, and the integrity is not good.
"The provincial department sent experts here, but the fingerprint was never successfully identified and analyzed." Gao Wenxiang and Wang Song changed places, and others obviously knew about the case.
So no one competed with Wang Song to let Lu Chuan analyze his case.
