crime profiler in the dark

"Since the promulgation of the "Silence Law" is only a matter of time, our way of handling cases needs to be changed to a large extent." Bai Haolin said as he opened the document, and suddenly he stopped flipping the book and looked at the police below. "Don't worry, I won't waste taxpayers' money by talking about some hard-to-understand noun explanations, but tell everyone how to apply psychology directly to the criminal investigation process, er, I said I was Let's talk about psychology?"

"Haha." Bai Haolin's humor made the police officers below laugh heartily, and the atmosphere was much more relaxed than it was at the beginning.

"According to the survey data of the Ministry of Support, 16% of the homicides in this department are intentional homicides, and 84% are manslaughter. Everyone knows that the sentencing of intentional homicide and manslaughter is completely different, and many prisoners also want to take advantage of the law. loophole, so how should we judge whether he is lying?" Bai Haolin said while turning on the video recorder and playing the expansion pack.

This is a video of the trial of a homicide case that caused great repercussions in TMX City.

A college student was notified that he would repeat a grade and killed his class teacher that night. The biggest controversy in the case at the time was whether the college student was insane at the time of the murder. If the answer is yes, then his sentencing will be more than intentional. Homicide is much less serious.

Bai Haolin started to play the video.

In the picture, the prosecutor walked up to the suspect and asked:

"At 2005:4 p.m. on April 13, [-], the victim called you to the office and told you that you would repeat a grade. At that time, there was testimony that you did not overreact, but left calmly. Is that true?"

"Yes." The suspect didn't look at the prosecutor when he spoke, but looked at his hands.

Bai Haolin pressed the pause button and asked the police officers:

"What do you think he is feeling at this time?"

"He didn't dare to make eye contact with the prosecutor, which means he is lying." Someone said.

"That's right, he was indeed lying. At the same time, he was looking at his hands, indicating that he was concentrating on suppressing the anger in his heart. Maybe he did leave calmly at that time, but he was about to explode in anger. Although it is an afterthought now, But I'm afraid he has already made a murderous attempt at that time." Bai Haolin explained.

Play continues.

"During the interrogation, you said that you don't remember what happened that night, can you explain it in detail?" the prosecutor asked.

"Knowing that I will repeat the grade, I went back to the dormitory and lay down for a while, but my heart was very confused, and I seemed to fall asleep in a daze. Later, when I woke up, I found that my whole body was covered with blood. I was very scared, so I washed the bloody clothes. And then the next day the police came looking for me."

Bai Haolin pressed the pause button, and zoomed in on the image, pointing to the slight depression on his face and said:

"It means he's biting his cheek, it shows he's nervous and he's hiding something."
