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

Chapter 144 Falling from a Building

The provincial-ministerial fingerprint competition is second only to the fingerprint competition organized by ministries and commissions every three years.

Generally speaking, they are all the most powerful fingerprint identification and analysis experts in the province, who gather together and swipe their fingerprints.

However, it does not mean that someone must choose to identify a case that has entered the fingerprint database of the battle.

This is the same as going out to sing, there will always be someone that everyone doesn't like, and no one will choose.

What's left is what's left.

Therefore, although this case has entered the fingerprint database of the provincial department, it is really uncertain whether it has been taken care of by experts.

Anyway, even if someone took care of it, but didn't understand it, no one would say it.

No one knows who can last for a few seconds.

The time for one cigarette is three to five minutes, and the time for two cigarettes is fifteen or six minutes.

Don't ask where the time in between goes.

Gao Wenxiang is fine for smoking two cigarettes in a row.

But smoking two Zhonghua cigarettes in a row, Gao Wenxiang needs to taste it.

Ding Dong!

Therefore, when Gao Wenxiang returned to the meeting room, he just heard the unique prompt sound that the fingerprint system comparison was successful.

On Lu Chuan's computer screen, four large characters were also displayed.

The red font displayed this time is obviously much more pleasing to the eye than yesterday's.

The comparison is successful!

"Successful again?"

The fingerprints that Lu Chuan targeted were all homicide cases.

Another success means that another murder case has been solved.

Lu Chuan nodded, feeling very fulfilled by doing this.

One fingerprint, one murder.

Done in two hours.

What could be more fulfilling than that.

Other than Gao Wenxiang, others also came over: "Ms. Lu...have you done another one?"

"Which case?"

Gao Wenxiang pouted: "Three years ago, the case in No. [-] High School."

"The high school student's case? Solved?"

There were exclamations one after another, obviously everyone was deeply impressed by the case back then.

Wang Kai's office.

Just after the morning meeting, Wang Kai sat down to have a cup of tea.

Humming a little song he liked when he was young, Wang Kai was in a great mood.

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

Haizhou is such a big city, not to mention that there are murders every day, but on average there are at least a dozen cases a year.

In addition to the murder case, there are many other cases.

Robbery, arson, robbery, theft, and more.

It can be said that there is no idle day.

But the situation last year was obviously much better, at least there were no new homicide cases added to the backlog.

This is the greatest success.

And the two-day fingerprint battle made Wang Kai feel even more happy.

Two homicide cases were uncovered in a row, both of which had a relatively large impact at the time. The important thing is that the suspect is as easy to catch as a chicken.

At the morning meeting this morning, Wang Kai was in a great mood seeing everyone's envious eyes.

If this trend continues, Wang Kai will be more likely to go further.

Ding.

The text message on the mobile phone sounded, and Wang Kai grabbed it casually.

puff!
A mouthful of hot tea was sprayed out.

"Cracked another one?"

Chen Degao, a student of Haizhou No. [-] High School, is a top student in the school with excellent academic performance.

After several preliminary examinations, the scores were all above 630 points, a proper 985 players.

The performance of the college entrance examination is also very stable, with a preliminary estimate of 640 points.

The life that was supposed to open up an infinite future disappeared in smoke at a class reunion after graduation.

Lu Chuan couldn't understand what the end of the college entrance examination meant.

There is no pressure of study, no parental discipline, and infinite vision for the future.

After Lu Chuan finished the college entrance examination that year, he played like crazy for two months.

Smoking and drinking were probably learned at that time.

"According to the students who attended the party at that time, they went to KTV to sing after eating, and clashed with the murderer on the way."

The case happened in the High-speed Railway New District, and Sun Miao was deeply impressed by the case.

"Probably because the other party molested Chen Degao's female classmate, they both drank a little wine and started arguing."

"Then it started. After Chen Degao was killed, the murderer ran away."

The process of the case was very simple, and there were many witnesses at the time.

But Chen Degao's classmate drank too much and couldn't remember each other's appearance at all.

It was dark again at that time, and there were people passing by around, and they only watched the excitement.

In addition, there is no monitoring near the crime scene, 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 criminal police to follow up every year.

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

That's how the case piled up.

In the fingerprint comparison system, an unfamiliar name was given.

Tian Yajun.

Male, 24 years old, does not live in Haizhou City, but lives in Tianzhou City next door.

According to the information, Tian Yajun is a barber.

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

"The murder of a high school student three years ago..."

Wang Kai also had an impression of this case: "The man is actually in Tianzhou..."

There are a lot of things to coordinate when arresting across cities.

Generally speaking, criminal police do not have the power to enforce laws in different places.

For example, to arrest people in Tianzhou City, it is necessary to coordinate with the Tianzhou City Criminal Police. If they agree, the Haizhou Criminal Police can arrest them.

Moreover, under normal circumstances, local cooperation is required.

Of course, rules are rules, and the actual situation is that there are very few people who do not cooperate.

As a criminal policeman, arresting people in different places is a common thing, and no one can guarantee that he will end up on someone else's territory one day.

After all, the criminal police all over the world are a family, most of them do their work with their heads up, and there are far more people who help than disrupt the situation.

As for such a trivial matter, Wang Kai usually doesn't need to come forward.

Hand it over to the Criminal Police Brigade of the High-speed Railway New Area.

You don't need many people, just four or five people in a squadron can handle the case.

They were busy catching people over there, while Lu Chuan chatted with everyone about the case, smoked a cigarette, and started comparing fingerprints again.

This reflects the cooperation between different types of police.

You do your fingerprints, I scratch mine.

With credit, we share together.

Of course, Lu Chuan contributed greatly to these three cases.

Of the thirteen homicide cases, Lu Chuan has already solved three of them, and there are two other cases that were not matched successfully.

In the rest, there are still eight cases.

This time, Lu Chuan did not choose a case randomly, but chose a homicide case that the Criminal Investigation Detachment received five years ago.

This is what Qin Yong just called to explain.

How can you not work for yourself when your own people go out.

Here we will talk about the relationship between the Criminal Police Brigade and the Criminal Investigation Detachment.

In terms of affiliation, the criminal investigation detachment is directly under the city bureau, and is at the same level as the district and county sub-bureaus.

Of course, in reality, the status is even higher.

The criminal police brigade, on the one hand, is subordinate to its own district and county sub-bureau, and on the other hand, it also accepts the leadership of the criminal investigation detachment.

No matter where a case occurs, the local police station is the first to receive the case.

If it is a murder case, the police station is to maintain order, and the criminal police brigade of the district and county is responsible for handling the case.

Only when major and important cases are encountered, and the district and county criminal police brigades are obviously unable to handle them, will they be handed over to the criminal investigation detachment.

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

Therefore, some murders will be in the detachment, and some murders will be in the criminal police brigade.

After restarting the computer, the CPU was fully rested, and Lu Chuan continued to sweep.

Five years ago, there was a fatal case of falling from a building in Qingjian Community.
