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

Circle culture exists in every industry.

For example, Lu Chuan's on-the-spot detective work, everyone is in the same circle, has relatively little communication with the outside world, and is relatively closed-off.

There are actually only so many capable detectives in the province, some of whom are good at fingerprint identification and analysis, some who are good at footprint analysis, and some who are good at bloodstain morphology analysis.

Of course, there are also people like Lu Chuan who are good at several abilities.

Lu Chuan had participated in the municipal bureau's fingerprint battle and the provincial department's fingerprint battle. After these two large-scale battles, he knew almost all the capable investigation detectives in the province.

The changes will not be particularly large in a short period of time, and this short period of time is actually not too short, it may be 10 or even 20 years.

The same is true for theft and robbery. Theft has its own circle of theft, and robbery has its own circle of robbery.

Lu Chuan had heard from Liu Guodong before that in the years when theft crimes were particularly rampant, the entire criminal gang organization even divided Haizhou City into areas.

Who is responsible for this urban area, who is responsible for this street, and who owns this community? They all have their own owners.

Many thieves will even check the location and mark the target door before committing theft.

That way, different people in the same organization won't fight with each other.

Foreigners passing by temporarily and enjoying the autumn breeze will not conflict with local forces.

The same goes for robberies, which are mostly committed by local gangsters.

The robber chosen by Lu Chuan had three previous criminal records.

Among them, there were two theft crimes and one robbery.

After confirming the personnel information, Lu Chuan sent it directly to Ren Qiang.

As a technical police officer, Lu Chuan does behind-the-scenes work and will not participate in arrests if he can.

In addition, whenever a case is handled, unity and cooperation must be emphasized, and different functional departments must cooperate with each other.

Lu Chuan found evidence while scanning the image. This was the key clue. After determining the identity of the criminal suspect, the arrest work should be completed by the action team.

With credit, everyone is equally divided. In a united group, it is not good to be alone.

Ren Qiang was chatting with Zhang Hui about the case of the past few days, and the Mobile Police Messenger on his phone received a message from Lu Chuan.

Ren Qiang was impressed by this case.

"Zhang Hui, look at this."

Zhang Hui glanced at it: "The robbery at Qianjin Street Police Station?"

The robbery was a major case, but it was hard to say how big it was. The first person to investigate the case was the Qianjin Street Police Station. After it was not solved, it was reported to the Criminal Police Brigade. The Criminal Police Brigade handed it over to the Criminal Investigation Detachment without solving the case.

The person who was robbed was not injured, but only lost some property. The criminal investigation detachment did not invest much effort at that time, which resulted in a backlog of cases.

Of course, once the case is in the hands of the criminal investigation detachment, it does not mean that it cannot be solved, but the effort invested is not proportional to the output.

You can't do this robbery according to the specifications of a murder case.

Judicial resources are limited at all times. Except for homicide cases, other cases still have to pay attention to the input-output ratio.

But now it's better. Lu Chuan directly locked the identity of the suspect, and the action team was responsible for the arrest.

The action team is absolutely familiar with the task of arresting a robber. Once they deal with a robber with more than a dozen big men, the other robber will not be able to escape at all.

"Let's call our brothers and let's go!"

Lu Chuan finished processing one backlog of cases and started the next one without stopping.There was no one to disturb the quiet underground laboratory. Lu Chuan and Forensic Doctor Shen also talked on the phone and told her that they had to deal with old backlog cases during the day, so they would not chat for the time being.

Therefore, Lu Chuan, who had nothing else in mind, was extremely clear-headed and high-spirited at the moment, and he was in the best condition.

This gave Lu Chuan the feeling that he had found a provincial department to participate in a fingerprint battle. He concentrated on solving the case without thinking about anything.

This time, Lu Chuan dealt with the only two backlogged theft cases last year.

Compared with the robbery case, this case was actually simpler for Lu Chuan.

The suspect committed the crime in a very sophisticated manner. He wore gloves when committing the crime and did not leave any fingerprint information at the scene.

However, it was impossible for the other party to float into the house while stealing, so he left footprints.

Regarding the footprint identification and analysis, Lu Chuan took the initiative and quickly completed the data measurement of the shoe prints.

The murderer was probably in a leisurely state when he committed the crime. He left hundreds of footprints in the living room and bedroom of the defendant's home.

This was the first time Lu Chuan had seen such rich footprints at a case scene, so the data obtained from the analysis was more accurate.

"Male, height 1 to 93 meters, weight 1 kilograms to 96 kilograms, walking with a weak splayed figure, left leg...suspected to have a fracture."

A person's footprint shape is affected by both congenital and acquired influences.

The main congenital factors are heredity, while there are many acquired factors.

Such as nutritional intake, physical development, bone condition, and external shocks.

Even for the same person at different ages and different physical development conditions, the shape of the footprints is slightly different.

But this difference should be continuously observable and conjectural.

However, once an external force is struck, such as a broken leg bone, it will have a sudden impact on a person's footprint shape.

In addition, this person is 1 to 93 meters tall. This height definitely belongs to a very small number of people.

Still using the old method, after Lu Chuan determined the basic information of the suspect, he pulled out the data on theft suspects over the years and compared them.

This time, the first thing Lu Chuan compared was the height options.

Compared with robbery, the number of suspects with criminal records for theft in Haizhou City is higher.

The main reason is that compared with robbery, the probability of being caught is relatively smaller.

If he is not caught once or twice, the criminal suspect will have a sense of self-confidence and the accumulation of proficient skills and experience.

It's just like some old perverts walking in an alley. When their eyes are raised and their eyes converge, they know who this person is without even saying hello.

Even the price is known.

Then you can complete a sublimation with satisfaction.

The smaller the probability of being caught, this leads to a larger base of suspects committing theft and more crimes.

But when people walk by the river, there is no way that their shoes will not get wet. The more they steal, the more likely they are to be caught.

After years of accumulation, almost all the thieves with accumulated skills in Haizhou City have been caught.

Therefore, Lu Chuan quickly found the corresponding criminal suspect in the criminal record suspect database this time.

After stretching, Lu Chuan sent the data to Sun Jun. (End of chapter)
