Start with Psychologist

Fang Ze was a little surprised: Didn't you think of it?

This should be pretty simple.

If you have carefully studied criminal science and technology and have a flexible mind, you can easily determine the direction of the investigation.

Really not? Don't be afraid to make a mistake.

Fang Ze confirmed it again.

Still no one raised their hand.

Seeing this, Fang Ze nodded and said, Okay, let me tell everyone.

Walking to the computer, Fang Ze zoomed in on some important photos.

The bloodstains in the car and the wounds of the deceased clearly appeared on the big screen.

After seeing these photos, Fang Mu was taken aback, as if he had thought of something.

Fang Ze said: Haven't everyone learned the form of bloodstains?

Who can recite the concept.

This time someone raised their hand.

That male classmate, tell me.

Fang Ze pointed to the back row.

The person who was called put down his hand and said loudly: The shape of the bloodstain, as the name suggests, is the shape and state of the bloodstain.

According to the different mechanisms of bloodstain formation, from the perspective of the dynamics of bloodstain formation, combined with the morphological characteristics of bloodstains, bloodstains can be divided into splashing, throwing, splashing, dripping, streaming, wiping, and transferring. , impregnated, diluted and blood pooled ten types.

Fang Ze nodded: Very well said.

The form of bloodstains is an important investigation basis in murder cases.

According to the difference in the shape of the bloodstains of the deceased, we can determine what the deceased experienced before he died.

The ten types of bloodstains mentioned by the classmate just now are a bit complicated. Today I will only talk about three simple ones.

Everyone think carefully.

First, mist-type bloodstains.

This bloodstain form mainly appears during high-speed impact.

For example, at the scene of a shooting,,, such traces of blood often appear.

Second, droplet blood stains.

This bloodstain form mainly appears during medium-speed impacts.

Such as fighting, or hitting with a blunt object.

Third, large blood drop type blood stain.

The form of this bloodstain is relatively simple, and it usually drips naturally.

Having said that, Fang Ze paused slightly, giving the students time to digest and think.

Sure enough, after Fang Ze gave the type of bloodstains, many students seemed to understand.

Because most of the bloodstains in the photos inside the car at the scene were micro-droplets, with only a small amount of large bloodstains.

This means that the deceased was injured or even died before the accident.

Plus the suspicious wounds on the body of the deceased.

An inference emerges.

Wang Zhiqiang violently attacked the deceased inside the car with a blunt or sharp weapon, and then created the illusion of a car accident.

It is impossible for a car accident to cause so much blood.

If that's the case, the driver won't survive

inside the classroom.

Fang Ze glanced at everyone.

The hints have been given very clearly.

As long as the students are not stupid, the process of committing the crime can basically be clearly restored.

If you are still at a loss, maybe you are really not suitable for the profession of criminal police.

At the very least, he is not suitable to be a front-line criminal police officer.

If you still want to be a police officer in the future, you can consider civilian employment.

Having said so much, do you understand?

Fang Ze asked.

Most of the students nodded.

it is good.

Fang Ze smiled and said, Who can explain the details of the reasoning and what to do next?

There was encouragement in Fang Ze's eyes.

At that moment, many students raised their hands and looked at Fang Ze expectantly.

They don't want to miss this opportunity to show their faces.

Fang Mu also raised his hand.

At this moment, he had thought everything through, without missing anything.

Fang Ze glanced at Fang Mu, but didn't call him.

He still wants to give other students some chances.
