The fingerprint battle of the provincial department is second only to the level of the fingerprint battle organized by the ministry once every three years. Generally speaking, they are the most powerful fingerprint identification and analysis experts in a province, gathered together, and swiped fingerprints.

However, it does not mean that if you enter the case of the battle fingerprint bank, someone will necessarily choose to identify it. It's the same as going out to sing, there are always people who everyone doesn't like, and no one chooses them.

What's left is left. Therefore, although this case has entered the fingerprint database of the provincial department, it is really impossible to say whether there are experts to take care of it.

Anyway, even if someone takes care of it, but they don't understand it, no one will say it. No one knows who will last a few seconds.

The effort of one cigarette is three to five minutes, and the effort of two cigarettes is fifteen or sixteen minutes. Don't ask where the time has gone.

Smoking two cigarettes in a row, Gao Wenxiang is no problem. But smoking two Chinese cigarettes in a row, Gao Wenxiang needs to taste it well.

Ding dong! Therefore, when returning to the conference room, Gao Wenxiang happened to hear the unique prompt sound of the successful comparison of the fingerprint system.

And Lu Chuan's computer screen is also displaying four big characters. The red font displayed this time is obviously much more pleasing to the eye than yesterday's.

Comparison success!

"Succeeded again?" The fingerprints targeted by Lu Chuan are all homicide cases. Another successful one means that another murder has been solved.

Lu Chuan nodded, this thing was done with a sense of accomplishment. One fingerprint, one homicide. Two hours to get it done.

What could be more fulfilling than that. In addition to Gao Wenxiang, others also came over: "Teacher Lu...... Got another one? ”

"Which case?" Gao Wenxiang Nunu mouthed: "Three years ago, the case of the third high school. ”

"The case of a high school student? Broken? The exclamations came and went, and it was obvious that everyone was deeply impressed by the case that year.

Wang Kai's office. Just after the morning meeting, Wang Kai sat down to have a cup of tea. Humming the little song he liked when he was young, Wang Kai was in a very good mood.

As the director in charge of criminal investigation, the pressure on Wang Kai has always been the most stressful of all the deputy positions.

Haizhou City is so big, not to mention that there are homicides every day, but there are at least a dozen cases on average a year.

In addition to homicides, there are also many other cases. Strong, arson, robbery, theft, and more. It can be said that there is no day to be idle.

But last year's situation was obviously much better, at least there were no new homicides. That's the biggest success.

And the fingerprint battle in the past two days made Wang Kai even more happy. Two homicide cases were solved in a row, and they were all relatively influential at that time, and the important thing is that the suspect is as easy to catch as a little chicken.

At today's morning meeting, looking at everyone's envious eyes, Wang Kai was in a very good mood. According to this trend, Wang Kai is more likely to go further.

Bite. The text message prompt on the mobile phone sounded, and Wang Kai grabbed it casually. Burst! A mouthful of hot tea squirted out.

"Another one?" Chen Degao, a student of Haizhou No. 3 High School, is a top student in the school.

Several preliminary exams, the scores are above 630 points, a proper 985 player. The performance of the college entrance examination is also very stable, with a preliminary estimate of 640 points.

A life that was supposed to start an infinite future disappeared in a class reunion after graduation.

What does it mean when the college entrance examination is over, Lu Chuan is clear. There is no pressure to study, no parental discipline, and infinite hope for the future.

After Lu Chuan's college entrance examination that year, he played like crazy for two months. I probably learned to smoke and drink at that time.

"According to the classmates who attended the party at the time, after they finished eating, they went to KTV to sing, and they clashed with the murderer on the way." The case happened in the high-speed rail new area, and Sun Miao was very impressed by the case.

"Probably because the other party molested Chen Degao's female classmate, they all drank some wine, and they quarreled."

"Then he did it, after Chen Degao was killed, the murderer ran away directly." The course of the case was very simple, and there were many eyewitnesses at the time.

But Chen Degao's classmates drank too much and couldn't remember each other's appearances at all. At that time, it was dark again, and there were people passing by, and they only watched the excitement.

In addition, there is no surveillance near the location of the crime, and the murderer has never been found. The criminal police brigade of the high-speed rail new area did not give up on this case, and arranged for the criminal police to follow up every year.

But I didn't remember what the other party looked like back then, and two or three years have passed, and those who have experienced it can't remember it clearly.

That's how the case accumulated. In the fingerprint comparison system, an unfamiliar name is given.

Tian Yajun. Male, 24 years old, does not live in Haizhou City, but in Tianzhou City next door. According to the information, Tian Yajun is a hairdresser.

Lu Chuan's comparison was successful, and Wang Kai directly saw the relevant case from the system.

In the case of "...... murder of a high school student three years ago", Wang Kai also had the impression that "people were arrested across prefectures and cities in Tianzhou ......", and there were many things to coordinate.

Generally speaking, the criminal police do not have the power to enforce the law in other places. For example, if someone is arrested in Tianzhou City, it is necessary to coordinate with the criminal police of Tianzhou City, and only when the other side agrees can the criminal police of Haizhou City arrest people.

And, in general, local cooperation is required. Of course, rules are rules, and the reality is that there are very few who do not cooperate.

It is common for criminal police officers to arrest people in other places, and no one can guarantee that they will go to other people's territory one day.

In the final analysis, the criminal police in the world are a family, and most of them do their work with their heads, and they help far more than the people who dismantle the stage.

And for such a trivial matter, Wang Kai generally doesn't have to come forward. It will be handed over to the criminal police brigade of the high-speed rail new area.

You don't need many people, a squadron, four or five people, you can handle the case. was busy arresting people over there, Lu Chuan chatted with everyone about the case here, smoked a cigarette, and began to compare fingerprints again.

This reflects the cooperation between different police departments. You do your fingerprints, I catch my people. With the credit, everyone shares it together.

Of course, Lu Chuan has a lot to do in these three cases. Of the thirteen homicide cases, Lu Chuan has already solved three of them, and two of the cases have not been successfully matched.

For the rest, there are still eight cases. This time, Lu Chuan did not choose a random case, but chose a homicide case that the criminal investigation detachment received five years ago.

This is what Qin Yong just called to explain. When your own people go out, how can you not work for yourself.

Here we have to talk about the relationship between the criminal police brigade and the criminal investigation detachment. In terms of subordination, the criminal investigation detachment is directly subordinate to the city bureau and is at the same level as the major district and county bureaus.

Of course, in practice, the status is even higher. On the one hand, the criminal police brigade is subordinate to its own district and county bureaus, and on the other hand, it also accepts the leadership of the criminal investigation detachment.

No matter where a case occurs, the first person to take over the case is the local police station. If it is a homicide, the police station is to maintain order, and it is the district and county criminal police brigade that handles the case.

Only when a major case is encountered, and the district and county criminal police brigades are obviously unable to handle it, will they be handed over to the criminal investigation detachment.

The Haizhou City Criminal Investigation Detachment is a little different, it has an internal action group, which is equivalent to a squadron of the Criminal Police Brigade, and also has its own jurisdiction.

Therefore, some homicides will be in the detachment, and some homicides will be in the criminal police brigade. Restarted the computer, fully resting the CPU, and Lu Chuan continued to sweep.

Five years ago, there was a case of death from a building in the Qingjian community.
