Half a day passed in the blink of an eye.

Since it is confirmed that the suspected murderer entered the victim’s home, it is certain to find him.

How to find it?

Community monitoring, Sky Eye (Skynet) monitoring, and visits.

From the surveillance cameras in the victim’s home, it can be inferred that the ‘murderer’ should have infiltrated at night.

Unfortunately, there is no monitoring in the corridors of residential buildings.

But.

After the surveillance in the community occurred, the police and Yuan’an had already investigated.

The sky eye monitoring outside the community was taken out, and no suspicious persons were found.

It is conceivable that the murderer must have been prepared and deliberately evaded surveillance.

Can you find people by just visiting?

No, but Xiao Yu still had a way to find him.

The residence of the victim, Song Ni, was a small high-rise building with a total of nine floors.

Her home was on the eighth floor, and there were no climbing points on the outer walls.

Entering from the outside, bottom-up, is certainly not OK.

Entering from the top down, there is still no technical content.

The roof of the building has been inspected by the second group, and no traces of sling tools have been found.

Xiao Yu personally checked it out, and finally confirmed that it was definitely not from the outside.

It can only be internal… Take the main entrance.

This is easier to check.

Five ways to get into the house.

Password, key, fingerprint, brush face, mobile app.

I have to say that the way the smart door is unlocked now is still more fancy.

Wang Dong led the team to investigate people who may have come into contact with the victim’s five ways of unlocking the lock.

Four types of people: family members, colleagues, relatives and friends, and masters who install smart doors.

The suspect was quickly locked.

The ex-boyfriend of the victim Song Ni’s girlfriend, Bai Yuguo!

Why him?

Through the second group of investigations, the master, family members, and colleagues who installed the smart door were all excluded from suspicion.

Then lock in the victim’s girlfriend Yan Tingting.

Yan Tingting did know the password of Song Ni’s smart door.

She herself was also excluded from suspicion, but the password was leaked by her.

Yan Tingting’s ex-boyfriend likes to flip through her mobile phone.

The password for the door of the girlfriend’s house is recorded in the mobile phone notepad.

“Capture the White Jade Kingdom!”

Xiao Yu issued an order, “After you get caught, bring the people directly.” ”

He had a hunch that something was wrong!

If this white jade country has the ability to hack into the victim’s smart device, it needs a password?

One more thing.

Bai Yuguo was an unemployed vagrant, and although he graduated from college, he did not study computer science.

The arrest process went smoothly.

In less than an hour, Bai Yuguo was put in front of Xiao Yu by two team members.

At the first sight of the other party, Xiao Yu frowned.

Definitely not!

Just look at the other party’s slumped in front of him, scared to pee his pants, the psychological quality is too poor.

The killing of twelve people should not be carried out.

He doesn’t deserve it!

“XX MONTH XX, THE NIGHT OF SIXTEEN DAYS AGO, WHERE WERE YOU?”

Xiao Yu coldly stared at the White Jade Kingdom in front of him.

Miserable white face, good looks, a little handsome, about eight or eight figures, but the eyes are not right.

“Me, I…”

Bai Yuguo’s eyes did not dare to look at Xiao Yu, “I don’t remember, it should be at home.” ”

Lie…… Xiao Yu sneered.

During the process of the other party’s answer, one side of the shoulder shook, indicating that he was not confident in his words.

The eyeballs are shifted to the right, and the body and language are inconsistent, indicating that he is lying.

Wang Dong on the side did not understand the micro-expression.

As an old man, observing the color is the basic exercise.

The leader of the group was angry, and directly pulled out the gun and put it on the door of Bai Yuguo’s brain.

Image, image, can you not be so simple and rude… Xiao Yu squinted his eyes at the elder brother and looked helpless.

However, simple and rough is very effective.

Bai Yuguo was not only frightened to pee, but also screamed, “I said, I said, that day, that day… I’m right here! ”

Wuhu…… Xiao Yu and Wang Dong glanced at each other.

Solved the case?

Stop it.

Again, he doesn’t deserve it!

“Say it.”

Xiao Yu coldly stared at the frightened and trembling Bai Yuguo, “Why are you in Song Ni’s house?” ”

“Me, I was thinking… Make love to her! ”

Bai Yuguo sighed, bowed his head, and answered in a low voice.

The two big group leaders sneered.

How to be a kiss, and how to make friends, are you serious about this affinity and making it?

Be sure to be clear!

Bai Yuguo confessed.

What he calls ‘affectionate communication’ is indeed unorthodox.

When he was still with his ex-girlfriend, he fell in love with the victim Song Ni and wanted to beat Song Ni.

Song Ni is very good-looking?

Very ordinary a girl.

Focus, there is money!

He earns a monthly salary of 20,000 yuan, has his own loan to buy his own property, and has six figures in deposits.

This condition is already ‘white and rich’ in the eyes of many boys.

At least after marriage, you don’t have to worry about the house, and there are indeed many boys who can’t afford to buy a house.

This is not to laugh at anyone, such as Xiao Yu himself.

If you are just an ordinary policeman, if you want to buy a house with his little salary, you have to save for decades.

Many boys actually have a dream of eating soft rice in their hearts.

The point is that it’s so fragrant!

Therefore, Bai Yuguo had already hit Song Ni’s idea.

Using his ex-girlfriend Yan Tingting, he has approached Song Ni five times in the past.

It’s a pity that Song Ni can’t look at him at all.

But once, Bai Yuguo used his hands and feet on people, and Song Ni was angry and told her girlfriend.

Because of this incident, bai yuguo broke up with his ex-girlfriend and also had a sense of revenge.

For half a year, Bai Yuguo began to ‘step on the point’ and tailgat.

He also learned an anti-reconnaissance technique online, how to evade surveillance, how to evade police tracking leads.

Within half a year, he took advantage of the fact that Song Ni was not at home in the middle of the night, using the door lock code he got from his ex-girlfriend to sneak into Song Ni’s residence.

Sixteen days ago, Bai Yuguo decided to attack Song Ni.

First, through anti-reconnaissance technology, evading surveillance cameras inside and outside the community.

Taking advantage of songni’s free time to go downstairs to eat with her girlfriend, she sneaked into Song ni’s house and hid behind the floor-to-ceiling curtains on the balcony.

Prepare to wait for Song Ni to come back and do something intimate to Song Ni.

When Song Ni returned, she didn’t wait for him to get ready to do it.

Outcome…… Bai Yuguo was frightened.

Frightened by a smart voice speaker, my scalp tingled and shuddered.

“That speaker, that speaker…”

At this time, Bai Yuguo’s pale face pointed to the corner, pointing to the smart speaker, “It is alive!” ”

There seemed to be an eerie atmosphere in the hall.

The members of the group got goosebumps and sweat.

Even Xiao Yu and Wang Dong took a deep breath.

Because their eyes are telling them.

At this moment, the White Jade Kingdom did not lie!
