Bro, you are a policeman, not a thug.

Xiao Mu's eyes were fixed on the windowsill and two marks on the outer wall.

1. A 'string' mark.

2. 'Missing' dust on the outer wall.

I've talked about it before.

As the air circulates, the particles and dust in the air will adhere to some objects.

As long as these places are moved, traces will inevitably be left, taking away or compacting the dust.

Through these two marks, Xiao Mu deduced that someone used a string to hang an object outside the window.

When the object was attached to the outer wall, it took away some dust particles.

Based on the area of ​​dust particles missing from the outer wall, it can be inferred that it was a 'bag-shaped object'.

Xiao Mu finally knew why the bacterial smell of that person disappeared.

Because there might be a pair of shoes in that bag-shaped object.

Put on shoes and cover the soles of the feet, will the bacterial smell of the soles of the feet disappear?

Of course, the bag may be more than a pair of shoes, there may be other things.

Something that can allow a person to disguise quickly.

In a very short time, from the surveillance, from people's sight, to become another person.

He doesn't even need to escape.

Because he is standing in front of you, you will automatically ignore him, and you will never think that he is the suspect.

Isn't it coquettish?

The hotel surveillance is retrieved again.

You can leave from the stairwell, and the places where you can appear, all surveillance!

The hotel has a total of nine floors, and there are nine exits that can be left from the stairwell.

Check the time period after the four national security personnel were knocked down.

As long as these nine exits are locked, he will definitely be found.

There is another key point.

In a building with an elevator, people rarely climb the stairs.

So there will definitely not be too many people who walk up the stairs.

And people who enter this stairwell will also be photographed by the surveillance.

The number of people is fixed.

As many people go in, they will definitely walk out.

There is absolutely no way that there will be one more or one less.

So during this time period, as long as there is one more person.

Then this person is the suspect.

You see, hasn't this person been found?

When Xiao Mu finished this reasoning, he told the two brothers.

Gao Shengli and Zhao Ming were embarrassed.

They looked at Xiao Mu with strange eyes.

It seems to be saying: Is the rice we eat different on weekdays? Or are we actually different species?

Otherwise, why can the boy in front of you think of it, but you can't?

When the surveillance video was fully investigated, the target was locked!

Just as Xiao Mu reasoned.

From the four national security personnel being knocked down, the suspect escaped.

There were a total of 8 people entering the stairwell before and after this time.

But when they came out, it became 9.

There was an extra female room cleaner!

When Xiao Mu saw this, his head buzzed.

A man not only turned into a woman, but also turned into a hotel cleaner.

Good tricks!

...

Night.

Quiet, with only a few insects chirping occasionally.

Xiao Mu was looking at a residential building.

Looking at the residence of the "hotel cleaner".

Watching the national security personnel rushing into the residential building...

Six minutes later.

The national security personnel came over with a woman.

No...

Xiao Mu only glanced at the other party and shook his head.

The real "cleaner" had already run away.

He could guess this.

Think about the other party's methods.

Before the suspect chose to live in the hotel involved in the case, he had already chosen this cleaner.

He used some means to control her.

When necessary, he could use the identity and appearance of this cleaner to escape from the hotel without arousing anyone's suspicion.

It would also give people the illusion of "disappearing out of thin air".

This method is not only fancy, but also very saucy.

As the national security personnel investigated the cleaner.

This is a divorced woman with a nine-year-old son who works in the hotel on weekdays.

Someone came to her, threatened her and her son's lives, and gave her 100,000 yuan.

This method is very simple and crude, a slap in the face plus a sweet date, and it is also very effective.

The community surveillance was retrieved and the suspect was locked.

Everyone knows it's useless.

People can disguise, cross-dress, change their faces, and change their bodies!

Xiao Mu held a cigarette in his mouth and looked at the night sky.

As I said, traditional criminal investigation is ineffective.

Don't use the criminal police's tricks to play with the special agents.

They are completely from two different worlds!

So how to investigate next?

Xiao Mu's mind was boiling like boiling water, and he began to reason, trying to find a way out from other places.

At this moment.

Suddenly, Xiao Mu's pupils shrank.

Who is spying on me?

In an instant, Xiao Mu turned around.

He looked at a residential building and a window.

He saw the curtain move.

Xiao Mu also moved.

He moved like a flash.

Almost instantly, he appeared in front of this residential building.

Boom, he broke open the unit door and rushed to the stairwell.

2nd floor, 3rd floor, 4th floor... Xiao Mu rushed into the corridor.

Bang... booming explosion.

The security door hit the ground.

Xiao Mu stood in the hall filled with smoke and dust.

He saw two men with changed faces.

He saw the monocular telescope that the other party had no time to hide.

I also saw a man loading bullets into a "special agent gun", .22 bullets.

The gun is very small and can only hold two bullets.

Anyone who knows about guns knows that as long as the .22 bullet hits the vital point, one shot can also kill the enemy.

When the opponent had just finished reloading his bullets and had not yet closed his special agent gun.

Xiao Mu was already standing in front of the man.

Snap.

He grabbed the opponent's neck and lifted it high.

As easy as picking up a chicken.

At the same time, one thigh was raised and kicked high.

Bang, hitting the other man's head.

The man's head flew horizontally and hit the wall as if hit by a battle axe.

His body slid along the wall and fell to the ground motionless, fainting.

Only then did Xiao Mu look at the man in his hand who was rolling his eyes due to suffocation.

He raised his hand and punched.

Bang!

Hit the opponent's lower abdomen.

Xiao Mu released his palm.

The man fell limply to the ground, his body curled up like a shrimp, with his mouth open.

Bang.

Xiao Mu's foot kicked the man's chin.

Coma.

The national security personnel had already rushed into the house at this time.

Without Xiao Mu's instructions, he stripped the two men naked and began to search.

A 'glass capsule' was found in the mouth of one of the men.

A 'mini syringe' was found in the hair of another man.

Until then, everyone breathed a sigh of relief.

Xiao Mu looked at the two unconscious men coldly.

No.

These two people were too trash and caught too easily.

They were definitely not the people they were looking for!

A strange idea popped up in Xiao Mu's head.

Why did these two people appear?

What qualifications do they have to participate in this incident?

But they just appeared.

"Tools? Tests? Or warning lines?"

Xiao Mu narrowed his eyes, "Or something else?"

Huh?

The feeling of being spied on appeared again.

Instant.

Xiao Mu looked at a socket on the wall in the hall.

He saw a camera hidden in the socket.

Something is wrong... Xiao Mu's face became gloomy.

What on earth do you want to do?
