Police officers rarely encounter cases of dead people, and when they do, they are handed over to forensic doctors for autopsies. All this knowledge has long been forgotten. Only criminal investigators will focus on learning these things.

"Since it's consistent with committing suicide by hanging," Gao Jiajia's head teacher was interrupted by Ai Liang as soon as she started speaking.

"The next thing is the key. The marks left by strangulation and suicide by hanging are completely different. People who are strangled will have strangulation marks on the back of their necks, while people who hang themselves will only have marks on their chin and neck.

Semi-circular strangulation marks.”

Ai Liang pointed at Gao Jiajia's neck. As he said, there were indeed strangulation marks on the back of the neck.

"When I put the body down, I observed the surface of the door frame. The skipping rope that hung Gao Jiajia was very worn, and some of the metal wires were leaking out of it.

Even if he hangs himself, the human survival instinct will prompt him to struggle, but there are no jump rope wires on the door frame, and there are no traces left by violent friction, so Gao Jiajia was strangled and hung at the door of the classroom."

A simple and easy-to-understand analysis left everyone present speechless.

Especially Gao Jiajia's head teacher, who looked at Ai Liang with a hint of fear.

A normal fourteen-year-old or fifteen-year-old student who stares at the horrific corpse without changing his expression during the interview? Can he analyze so much knowledge about human body structure? I'm afraid he is not a potential psychopath.

In the past, Ai Liang's calmness and good habit of loving reading but not talking became weird in his eyes. Most of the perverted killers in movies wore this kind of appearance.

This is not over yet, Ai Liang is still continuing to analyze.

"Gao Jiajia's corpse had opaque cornea, shrunken lips, and the corpse spots on the legs had merged to form large areas of corpse spots. Based on the movements when it was removed, it was inferred that rigor mortis had also spread to the whole body. From this, it was inferred that the time of death was at least more than six hours. It is estimated that

It was probably between nine and ten o'clock yesterday."

"Of course, what I said are only external observations and some inferences. Internal examination and histological examination still need to be dissected to determine."

After speaking, Ai Liang looked at the police officer, as if to verify whether what he said was right.

Look at what I'm doing, who knows what you're talking about!

The police officer held his breath deep in his heart, but nodded in agreement on the surface. After all, what he said seemed to make sense.

After more than ten minutes, the body was finally sent away, and the police officer breathed a sigh of relief. He no longer had to worry about the student's problem. It felt like the police academy exam back then.

"This classmate, please come with us. After all, you are the last person who has seen the deceased, and you were the first to discover the body. This does not mean that you are the murderer. This is just a process."

The police officer's words were polite, but with a hint of doubt. After all, Ai Liang's suspicion was not as high as before the investigation was clear.

"Yeah, no problem."

Ai Liang didn't say anything nonsense like he was innocent, and stood quietly behind the police officer.

I even had the time to ask Gao Jiajia, the head teacher, to ask for a leave.

The more critical the situation, the more a person's actions can reflect a person's character. Ai Liang's strong psychological quality makes him, a policeman, speechless.
