Chapter 30: Psychology of Micro-Expressions and Movements

The victim's home.

"The clues are broken."

Xiao Yu looked at the 'blood and flesh painting' on the wall and seemed very calm. "He is very smart and should have planned it for a long time. He even did a perfect job on how to enter the victim's home and the finishing work after leaving. He can consider all these things. It should be difficult to find other clues at the scene."

The members of the task force were all looking at Xiao Yu quietly with serious expressions.

Although they just met Xiao Yu today.

But the feeling of this trainee police officer to them was only two words: pervert!

The powerful and terrifying investigation ability and the unrestrained thinking.

It was a little difficult for them to accept.

Therefore, as the leader of the task force, Niu Peng took some time to retrieve Xiao Yu's file through his mobile phone.

You don't know until you see it. After reading it, you are speechless.

It turns out that he is the only one in the police academy, the kind that makes people's scalps numb.

The academic bully in the police academy is still the fighter among the academic bullies.

When Niu Peng told the other members of the team, everyone suddenly realized it.

A top student in the police academy?

That's fine!

Niu Peng made a decision. Xiao Yu will temporarily command the task force and everyone will cooperate.

Is there a problem with this?

Of course not.

You have been investigating for two days, but you didn't find any clues about Mao.

Xiao Yu came for a long time and found a major clue.

Although the clues were broken, his ability is better than all of you put together.

This is the case within the police force.

When solving a case, no matter what age, position, or rank, get out of here.

Those who have the ability will do it, and those who don't have the ability will obey the command. This is the reality.

If the case can be solved, everyone will benefit from it.

Xiao Yu will get the first credit, and everyone can also eat meat and drink soup.

If the case cannot be solved, everyone will be unlucky, and no one can escape...

"Investigate the case, check the clues, check the details, and make bold guesses."

Xiao Yu's eyes moved away from the flesh-and-blood painting on the wall and looked at the team members, "But this may not be the truth, and it needs to be verified."

Everyone nodded, they are all old criminal detectives and they all understand this principle.

"Since the clues are broken, let's look for them somewhere else."

Xiao Yu narrowed his eyes, "First, interrogate the suspect!"

Why do we have to interrogate the suspect?

The murderer did so much but let the suspect take the blame for him and become a scapegoat.

How many normal people have nothing to do to frame others for fun?

Is it hatred? Is it revenge? Or something else?

Xiao Yu thought it might be none of them.

There should be no clues on this wrongly accused suspect.

Suppose he has hatred with the murderer, and the murderer wants to take revenge on him.

With the means by which the murderer committed such a tragic crime, why didn't he just attack him?

Why bother so much?

Interrogation is now a last resort, and no possibility will be let go.

The team members returned to the detachment to wait, and Xiao Yu and Niu Peng went straight to the detention center...

...

After a set of interrogation procedures.

In the interrogation room of the detention center, Xiao Yu saw the suspect of this case.

He is of medium build and ordinary appearance, barely a young man.

He was wearing a vest from the detention center, with a face of decadence, despair, and anger.

He Xiao, 29 years old, a local, a private company employee...

Since you know that he might be wrongly accused, why not release him?

There is a procedure.

First of all, the other party is indeed very suspicious, sleeping at the scene of the crime, and the clues and evidence all point to him.

Just these points alone cannot release him.

It doesn't matter if he is wrongly accused, he can apply for state compensation, and the police system will restore his reputation.

Is it unlucky?

It is indeed unlucky, but there is no way, who made you involved in the case.

That is, nowadays, if it was in the past.

If you encounter a sloppy person handling the case, you can wait for the execution ground to be shot...

"I am wronged."

Facing the two policemen, He Xiao stared with bloodshot eyes and roared.

"Well, I know."

Xiao Yu nodded calmly.

"Uh..."

Xiao Yu's words made He Xiao unable to deal with it.

After a while, he was excited and thought: Could it be that the police have found the real murderer?

However, the policemen in front of him were silent again.

He Xiao was anxious.

Are you still human when you are talking halfway?

Xiao Yu was silent, observing He Xiao.

Looking at He Xiao's expression and details of his demeanor.

In fact, some truths are hidden in the expression.

People's expressions basically come from psychology.

For example, real surprise will not exceed one second, looking down means recalling, looking up means making up a story, and unconscious shaking of the eyes means either lying or panic.

People generally blink five to eight times per minute. Too high a frequency means that the heart is unstable.

When lying, the heart rate is generally fast, the face will be congested, and sometimes the nose will itch and can't help touching it.

When a person is really angry, both the expression and the language are synchronized.

If the expression and language are not synchronized, then it is acting...

There are special teachers in the police academy to teach these knowledge, which is also the so-called "micro-expression" psychology.

The reason why the police have a pair of sharp eyes is because they know how to observe "micro-expressions".

After observing for two minutes, Xiao Yu was very sure.

He Xiao in front of him was indeed an unlucky guy.

Very unfair.

However, Xiao Yu found something wrong.

The other party had a pair of very steady hands.

So steady that no matter whether he was excited, angry, or desperate, his hands would never move.

This is unscientific.

You know, when people are in an uncontrolled state of mind, their bodies will react naturally and they will unconsciously make movements to reflect their mood.

For example, some people will subconsciously clench their fists when they are angry, rub their hands when they are excited, and dance when they are happy...

He Xiao in front of me did not make any body movements.

Something is wrong! .
