Start with Psychic Forensics

Fang Ze opened his mouth and said, "Have you not learned about the shape of bloodstains?"

"Who can recite concepts."

This time someone raised their hand.

"That male classmate, you say."

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, flowing, wiping, and transferring. , ten types of disseminated, diluted and blood pools.”

Fang Ze nodded: "Well said."

"The form of bloodstains is a very important basis for investigation in murder cases."

"According to the different bloodstains of the deceased, we can judge 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 the three simple ones."

"Everyone think hard."

"First, misty bloodstains."

"This form of bloodstains mainly occurs during high-speed impacts."

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

"Second, droplet bloodstain."

"This form of bloodstains mainly occurs during medium-speed impacts."

"Like a fight, or a blunt blow."

"Third, the bloodstain of the big blood drop type."

"This kind of bloodstain is relatively simple, usually dripping naturally."

Speaking of which, Fang Ze paused slightly, giving the students time to digest and think.

Sure enough, when Fang Ze gave the type of blood stains, many students seemed to understand a little bit.

Because of the inside photos of the scene, most of the bloodstains are almost microdroplet bloodstains, with only a small amount of large blood droplets.

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

Plus suspicious wounds on the deceased's body.

An inference emerges.

Wang Zhiqiang used blunt or sharp weapons to violently attack the deceased in the car, and then created the illusion of a car accident.

The car accident, it is impossible to leave so much blood residue.

If that were the case, the driver wouldn't be alive

Chapter 373 The end of the course [1]

Inside the classroom.

Fang Ze glanced at everyone.

The prompts have been given very clearly.

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

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

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

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

"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?"

Fang Ze's eyes were filled with encouragement.

At the 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 has already figured out everything, without any omissions.

Fang Ze glanced at Fang Mu, but did not call him.

He still wanted to give other students some opportunities.
