I know that Lin Ying has no malicious intent. Since Shen Yu participated in the case consultant work of the police station, in order to investigate and discuss the case, she often spent time with Lin Ying until midnight, and sometimes even worked all night.

Lin Ying didn't know that Shen Yu would transform after zero o'clock, so she naturally wanted to discuss with her the important clues she had just discovered, just like before.

When you read this, you may feel that it is the same as reading other detective novels, that is, the police often play a supporting role in the story, and their ability always seems a little weak - why do many cases have to wait for a detective to solve them?

In fictional novels, because you want to establish the image of the main characters, it is normal to hang them and put some protagonists on them.

But in real cases, this is not the case, the work done by the police department is very scientific, serious, compliant and reasonable, not only these, if you take some routines in detective novels to the real criminal police, you may only get a slap in the eye.

The work of the criminal police is roughly divided into two categories: technical work and investigation work, the so-called technical work, including on-site investigation, trace inspection, forensic dissection, biochemical experiments, space-time confirmation and even on-site photography, etc., do not underestimate the technical personnel, they can find the most direct and critical clues from the clues.

Even taking pictures on the spot is a technical job. A corpse cannot be placed on the scene forever, and the scene cannot be sealed forever, so taking photos and videos is an important basis for re-investigation after the survey.

Of course, there are also on-site photographers in the world who can be hung in all directions, such as people like me who will remember everything after watching the scene.

Investigation, on the other hand, includes visits, investigations, tracking, control, surveillance, analysis, confirmation, and many other aspects.

Investigators work very hard, and with a limited budget, sometimes they really sleep in order to solve crimes, and in addition, they also face a lot of uncertain dangers. They need courage, but they also need a cool head.

Lin Ying once told me about a case.

One morning, when an old man who was exercising in the morning passed by the door of a convenience store, he found a black and red color in the crack of the door below.

The old man had fought in his early years, and he immediately smelled the smell of blood in the air, so he calmly and calmly called the police.

Lin Ying and they led people to the scene, the deceased was the convenience store proprietor, she had knife wounds all over her body, but most of the wounds were deep or shallow, and the fatal wound was a knife to the chest, which happened to pierce her heart.

The cash register of the convenience store was pried open, all the money inside was lost, in addition, the deceased's mobile phone was also taken, and the murderer also took away a lot of convenience food.

After the on-site investigation and autopsy by technicians, it was preliminarily determined that this was a robbery and murder case, and that there were four murderers, one of whom was left-handed.

Investigators immediately launched an investigation, through visits and on-site monitoring and analysis, and finally found the traces of this group of people, they are four eighteen or nineteen-year-old young people, wandering around all day with nothing to do, and the police also found their rented residence in the urban-rural junction.

However, when Lin Ying and the others led the team to round up, they found that the group had moved away two days ago.

The detectives were a little annoyed for a while - judging from the methods of this group, they had become a gang of outlaws, and judging from the wounds on the corpses, there was a ruthless guy among the four people, he was the leader of this group, and he coerced some of his younger brothers to also "participate" in the killing, so as to put them on the road of no return for their own use.

Those shallow, crooked scars were the assassinations that the younger brothers were forced to kill in fear, and the fatal wound that penetrated deep into the heart should be the last mending knife of the leader.

Judging from the means of committing the crime, the purpose of this group of people is property, and they did not grab much money from the convenience store, and if they are not arrested as soon as possible, they are likely to commit new crimes.

The roundup failed, and Lin Ying was also a little disappointed. But she couldn't show it, she returned to the police station and continued to send all the investigators out to investigate. Because of overtime and lunch time in the cafeteria, she decided to take Xiaoyu to the fast food restaurant in front of the police station to have something to eat.

The police station is near the downtown area of Jiangyi District, and the road is narrow, and there is a large flow of vehicles and people. The two of them ordered two set meals at the fast-food restaurant on the second floor, and they both ate them like chewing wax.

But at this moment, Lin Ying suddenly found traces of the group in the crowd downstairs.

That's right, it's the same group of people, and the appearance of these people has long been engraved in her mind!

The flat-headed brother who walked in front was the leader, but this time he brought five people, two more than the original, and it seemed that he was the new little brother.

Lin Ying didn't care about eating, she slapped the table and ran downstairs.

Two female policemen followed the crowd, and these people were too bold to run to the door of the police station.

They walked casually on the street, and Lin Ying found that everyone's pockets or waist clothes were bulging, and there should be some kind of murder weapon stuffed.

What exactly do they want to do? Can't you want to grab money in the downtown area?

But what she didn't expect was that the six murderers did not rob, they swayed into an Internet café with cigarettes in their mouths.

Xiao Yu excitedly raised his feet and was about to rush in, but was stopped by Lin Ying and hugged him.

"What are you doing?" Lin Ying asked in a low voice.

"Boss, let's go in and arrest someone! Don't let them run away again in a moment! "Xiao Yu is already impatient.

"No way!"

Lin Ying's mind was spinning quickly - there were six murderers in total, all of whom might be carrying murder weapons, and the Internet café was densely populated, once the arrest failed, the murderer was likely to take hostages to fight, and it would be even more impossible to end.

To succeed, there must be enough deterrents!

However, all the colleagues in the police station were sent out to investigate, except for a few people in the technical section who were on duty, and the others were civilian personnel and their strength was very weak.

What to do?

Lin Ying suddenly remembered someone, she whispered something in Xiao Yu's ear, Xiao Yu nodded immediately, and the two of them walked quickly towards the Internet café.

"Boss, there are two entrances and exits, and there is a back door in the courtyard, and there are no windows."

"Is there a passage up the stairs?"

"There's a small staircase."

"Got it." Lin Ying said and took out her mobile phone and called the armed police department, "Captain Su, I'm here at the Perak Internet Café on Fengtai Street, is it convenient for you to transfer people to support?" There were six armed gangsters in the Internet café, and they were not alarmed. ”

"Great!" Captain Su said excitedly, "Recently, the soldiers have practiced a body of tendons, and they are worried about finding a task!" How many people do you want? ”

Lin Ying estimated: "I am at the scene with another colleague, it is best to need ten heavily armed people, can you arrange it over there?" ”

"This ......," Captain Su hesitated, sounding very embarrassed, "can I ask for it as much as I can?" ”
