6:[-] am.

Xiao Yuzheng, who was holding pancakes and fruit, wolfed down the pancakes and stood in front of an Internet cafe, waving his hands.

Two national security officers walked into the Internet cafe.

three minutes.

Like dragging a dog to death, two national security officers took out a man in his thirties from the Internet cafe and walked to a commercial vehicle on the side of the road.

Yu Yong, 31 years old, specializes in selling fake certificates, real certificates, real and fake invoices...

The major suspect in the drug trafficking case was the real ID card purchased from him.

To arrest him, Xiao Yu wanted to know the ID card information used by the suspects.

five minutes.

A national security officer opened the car door and walked up to Xiao Yu who had swallowed the last bite of pancake fruit. "Here we go."

It took five minutes to recruit...Xiao Yule.

There is a saying in the police community: the smaller the case, the quicker the confession.

Entering the commercial vehicle, Xiao Yu sat next to the suspect Yu Yong.

The other party's face had turned pale, and his whole body was shaking like chaff.

"Don't be afraid, I won't hit you."

Xiao Yu took out four photos of the suspect, "If you say you don't know him, I might kill you!"

Yu Yong:......

He stared at the four photos for a while, then suddenly his eyes lit up and he nodded quickly, "I know him. One of them bought ID cards from me. He bought four of them. He was introduced by another client of mine. "

"Do you still remember the ID card information he purchased?" Xiao Yuxiao asked.

"...can't remember!"

Yu Yong was frightened, "But I have records, so I have to check them on the computer."

"Okay, check quickly."

Xiao Yu patted him on the shoulder, "I'm in a hurry!"

15 minute later.

Four ID card information were placed in front of Xiao Yu.

Conduct investigations through police big data and find travel records.

For eight days, all four ID cards have usage records.

I have used the mobile APP to book four train tickets to Western Region Province.

Seven days ago, at 8pm, I boarded the Beijing West-Urumqi flight.

The whole journey takes 30 hours...

Xiao Yu roughly calculated the time and pondered a little.

Could it be that he really fled to Badie from the Western Regions?

But with his experience.

The more obvious the traces left by the criminal, the more likely it is that it was deception.

Later, Xiao Yu came to Beijing West Railway Station.

Retrieve the monitoring of the day.

It was discovered that at [-]pm seven days ago, four major suspects indeed entered the West Railway Station, checked in, and boarded the train.

Using his authority, Xiao Yu called up the station monitoring again.

Check the car where the suspect is located.

Such surveillance cameras are installed on both sides of the carriage aisle.

"what?"

Xiao Yu stared at the surveillance camera and looked at the four suspects sitting in their seats.

The clothes and hats are correct, the body shape is quite different, the mask and hat are never removed, and the face cannot be seen.

But his experience told him that something was very wrong with these four people.

The surveillance video of the four suspects checking tickets at the West Railway Station was again retrieved.

Xiao Yu then compared the videos of the four suspects in the car.

Beast form: Eagle Eye.

Xiao Yu carefully observed the posture and appearance of the four suspects...

Sudden.

Xiao Yu's eyes flashed with a cold light, staring at the suspect's shoes.

After checking in, I found the shoes of four suspects, three pairs of leather shoes, and one pair of basketball shoes.

The train carriage contained the four suspects’ shoes, two pairs of leather shoes and two pairs of skateboard shoes.

"Are you playing this with your dad?" Xiao Yu sneered.

But it has to be said that the four suspects have very strong anti-reconnaissance capabilities.

Actually, under surveillance, I can even play a game of 'civet cat for prince' for you.

Thousands of calculations, a hundred secrets and a sparse!

This is also normal.

People hate wearing other people's shoes.

Dirty, athlete's foot, fit... and a kind of disgust from the bottom of my heart.

Even the best friends rarely exchange shoes.

and so……

The four suspects who checked the tickets were real.

The suspect who got on the train was fake.

“Where did the package swap begin?”

Xiao Yu squinted and carefully observed the surveillance video of the four suspects entering the station.

The train station is monitored 90% of the way from the ticket gate to getting on the train.

It is quite difficult to drop packets under surveillance.

So it can only be done in those 10% areas.

The problem is coming.

How did the four suspects know that there were surveillance blind spots in the section from ticket checking to boarding the train?

Xiao Yu's face turned cold.

Whether it is past life or present life.

What he hates most is public servants violating laws and disciplines.

Not only the common people hate this kind of people, but the police also hate them.

Because it is often difficult to arrest people within these systems, which normal people can imagine.

Beijing West Railway Station, station police room.

Xiao Yu opened the door and walked in.

"Ok?"

The two policemen who were talking looked over and one of them stood up, "What do you want..."

Before he finished speaking, a national security officer held his shoulders and sat down again.

"National Security."

Another national security officer flashed a reconnaissance certificate.

The expressions of the two policemen changed and they looked frightened, but they were not too panicked, just confused.

Xiao Yu, who had a cold face, looked much more relaxed.

They didn’t do anything bad and weren’t afraid of ghosts knocking on the door. The expressions and demeanor of the two police officers were not too abnormal.

Xiao Yu showed a smile and said, "Seven days ago, you were on duty, right?"

"Yes." A policeman answered honestly.

"From checking in to getting on the train."

Xiao Yu looked into the eyes of the two policemen and said, "There is a surveillance blind spot, right?"

"Yes." The two policemen nodded.

Xiao Yu raised his hand, and a national security officer handed over a tablet computer.

He woke up the flat-panel elevator, called up two surveillance images, handed them to two police officers, and asked, "These are eight people."

The two policemen looked at the identical 'four people' on the two surveillance screens and were confused.

But after all, they are all engaged in criminal investigation, so don’t use bean bags as dry food.

After Xiao Yu's prompting, the faces of the two police officers gradually became ugly.

They discovered that there were indeed eight people.

Four people took the place of the other four and boarded the train.

This kind of thing is dereliction of duty for them.

At this time, everyone who was watching Guoan came to the door.

Their faces had begun to turn pale.

Is this the time for something big to happen?

"Don't worry, it has nothing to do with you."

Xiao Yu smiled and said, "You just need to tell me, who has the ability to bring four people into the platform in advance, and then take the other four people out of the platform after the package is changed, without being discovered?"

In fact, the answer goes without saying.

Internal staff at the railway station, people in charge of the platform.

Twenty minutes later.

The list of personnel who managed platform access and platform safety precautions seven days ago was placed in front of Xiao Yu.

A total of six people.

Within two hours, all six people were arrested and escorted to Xiao Yu.

"Seven days ago."

Xiao Yu stared at the six people and asked word by word, "Who helped the four suspects leave the station platform?"

After saying this, his eyes moved quickly.

Using micro-expression psychology, observe the faces, eyes, and expressions of six people.

Until it is locked on a person's face.

"take away!"
