Section 501

With a bang, he jumped from the fifth floor to the ground, half squatting with his body cushioned.

The moment he stood up, Yang Xu flew past him.

He ran towards the residential building where the woman's scream had just come out.

Arriving at the residential building where the screams came from, Zhou Chen's expression changed.

Also on the fifth floor.

Judging from the building layout of the community, the floor, seat, and layout of the woman who had just been followed and robbed were almost identical.

Thinking of this, Zhou Chen's body ejected and his limbs stuck against the outer wall of the residential building.

Using his hands and feet like Spider-Man, he quickly climbed up to the fifth floor and came to the window.

The window is open.

The scream just now came from here.

Looking into the room, Zhou Chen's pupils shrank.

I saw a woman lying in a pool of blood in the bedroom.

The woman was completely naked, with signs of being violated.

Her life was fading away and she could no longer be saved.

The cause of death was two apparent stab wounds on the chest and neck.

There was blood flowing underneath the body.

The sense of smell doubled... Zhou Chen wrinkled his nose a few times, and the smell of the room entered his nasal cavity.

moment.

Zhou Chen's limbs detached themselves from the wall and fell vertically from the fifth floor to the first floor...

It is inferred based on the time when the woman was murdered and the last scream occurred.

The murderer did not have enough time to leave the residential building.

The first thing Zhou Chen had to do was to block the main entrance.

Turn on the hearing doubling ability and monitor ‘abnormal noises’ around residential buildings.

It is basically impossible for the murderer to escape from other residents' homes. The only escape routes are the main entrance, the stairwell, and the use of ropes.

After calculating all the murderer's escape routes, Zhou Chen ordered Yang Xu in a cold voice, "Seal down."

Yang Xu's expression changed, and he pressed the wireless headset next to his ear, "The whole community is blocked, and no one is allowed to enter or leave!"

Outside the community, national security personnel and police quickly surrounded the community.

"How are you doing?" Yang Xu asked.

"Dead!" Zhou Chen looked ugly.

He and Yang Xu had already arranged everything, and they could still let people be killed. This slap in the face hurt a bit.

It can be said that the murderer doesn't play by the rules.

The murder process was not what Zhao Yutong had 'foreseen' in the building.

But if this is a battlefield, will the enemy follow the rules with you?

What's even more surprising is that.

When the entire community was surrounded, residential buildings were cordoned off.

Zhou Chen and Yang Xu went upstairs to arrest someone and search for the murderer.

A body was found!

Zhou Chen and Yang Xu, who were standing on the rooftop of the residential building, were both stunned, looking at the body lying in front of them.

Seeing the other person dying, he still held a dagger pierced into his chest and stared.

There was still an expression of anger, despair, and pain on his face.

After coming back to his senses, Zhou Chen looked around.

Seeing a rope that had been tied to the edge of the rooftop, his face turned cold.

The brain is spinning wildly, reasoning.

It cannot be found from the rope. The opponent is fully prepared and has designed an escape route.

It is even possible that the police will surround the community and residential buildings.

But it would be difficult for a normal person to imagine that someone would escape from the rooftop, mostly blocking the main entrance.

Since everything has been prepared in advance.

What does suicide mean?

Zhou Chen's eyes moved and looked at the mobile phone beside the body.

When he picked it up, his expression changed again.

The phone's system was actually restored?

You don't need to guess to know that the other party erased all traces of his cell phone before he died.

Click!

The phone was broken into pieces and was forcibly taken apart. There was no calling card inside.

Using social software to communicate... Zhou Chen's expression changed.

To communicate online, you must have an Internet connection.

What network is the other party using?

Of course, there is no point even if it is found.

Because when the phone system is restored, it is almost impossible to find out what software the other party uses to communicate.

All traces have been erased!

By placing the mobile phone next to the body, it can be inferred that the murderer probably communicated with someone through letters before committing suicide.

It can be deduced that it was because of this communication that the murderer gave up his escape and chose to commit suicide.

All clues were lost at this moment.

The medical examiner arrived and began an on-site autopsy.

After it was confirmed that he died by suicide. Everyone came to the fifth floor and looked at the female body.

After the forensic autopsy, it was confirmed that the deceased was violently treated and raped before death.

After Yang Xu inspected the scene, he confirmed that the murderer had entered the deceased's home.

The whole case is very obvious, including home invasion, robbery, rape, murder, and then suicide.

It feels like the murderer chose to commit suicide because he knew he couldn't escape... 0

And in fact.

The murderer could not have 'predicted' that he would be surrounded by the police, but committed suicide 'in advance'.

The identities of the deceased and the murderer have been confirmed through big data face scanning.

The victim, Cui Lanxin, female, 27 years old, from City A, worked as a bar server...

The suspect, Gong Qiang, male, 32 years old, from City A, property owner, socially idle, has a criminal record, and was sentenced to four years in prison for robbery and two suspended sentences for three years for intentional injury...

Through investigation, it was found that the two had no intersection in the past and were completely strangers.

Zhou Chen looked coldly as he watched the national security technicians remove the hard drive from the phone.

Start to restore some data stored on it in the past, mainly looking for communication software data.

Find out what software the murderer used to communicate before he died.

At the same time, the National Security Bureau investigated the network used by the mobile phone.

City WIFI!

The so-called city WiFi is a WiFi network established by the three major operators in the city through some signal transmitters.

No phone card is needed, you can directly use the mobile phone's built-in WiFi to connect to the Internet.

But it costs money!

Through the suspect Gong Qiang's ID card information query.

Two months ago, he had registered an account and subscribed to the monthly city WiFi service...

...

In a business car.

A man with both hands tied with cable ties and a 5.5-meter-tall body like a bear woke up slowly.

He saw Zhou Chen sitting in front of him, smoking.

All the memories before being knocked unconscious came to his mind, and the man's face changed drastically.

"Answer me a question."

Zhou Chen looked at him coldly, "Did you want to break into the house and rob alone, or did someone instruct you to come and rob?"

The man was silent and kept silent.

Bang!

A bullet pierced the man's foot.

"Ah!"

The man screamed.

The palm moved, the muzzle of the gun was aimed at the man's thigh, and Zhou Chen said coldly: "Answer me."

The man wailed, as if he didn't hear it.

Bang... The man's thigh was hit by a bullet.
