Chapter 189

Zeng Li was talking about the case while writing down useful information on another board.

"If anyone has any ideas, please speak up."

A handsome boy raised his hand first.

"He hates women and specifically targets them, but there's no sexual assault. He's not good at it, or he needs to abuse others to ejaculate."

Zeng Li glanced at him and asked, "What's your name?"

"Teacher, my name is Cheng Yunqing."

Zeng Li gestured for the other party to sit down.

"Is there anyone else?"

"Speak boldly, don't be afraid of making mistakes, and have your own ideas. The process of solving a case is to constantly eliminate wrong options and finally get the right answer."

No one spoke.

Zeng Li glanced at the calendar on the computer.

"The case file shouldn't leave the bureau, but do you know why it's in my hands?"

"I forgot to tell you that I'm still in school myself. I'm just taking time out to teach you."

"The country lacks talent, talent in all areas."

"I'm standing here to train as many talents as possible for the country. If you all don't have your own ideas and are as silent as quails, afraid of making mistakes or saying the wrong thing, who will the country's future depend on? Can we really rely on you?"

Zeng Li did not lose her temper. She said these words lightly, looking at the students below with contempt. This expression and the last sentence soon attracted the attention of the higher-ups who began to speak one after another.

Zeng Li doesn’t say what is right or wrong, but encourages everyone to think proactively.

Write more case information on the blackboard.

The atmosphere quickly heated up. No matter whether someone was right or wrong, as long as they said something they thought was wrong, they could refute it.

They slowly started to quarrel, after all, they were just young and hot-tempered kids.

Zeng Li patted the table.

"Listen to me now."

"Judging from the time the bodies were dumped, it's highly likely the perpetrator had a stable job. Assuming that's the case, how did these deceased people come into contact with the murderer? Was it work? Or something else?"

“What kind of job allows you to reach so many young women?”

"Why torture them? Is it out of vengeance or, as Cheng Yunqing said, for pleasure?"

"Why is your asshole so clean? None of you raised any objections. You can't be so thin-skinned in this line of work."

"Who would be so concerned about whether their asshole is clean?"

“How did this mentality develop?”

"Were long hair and youth the killer's criteria for choosing his victims? Or was it just a coincidence?"

"First, keep asking yourself questions, come up with hypotheses, and reason according to what you believe to be the correct logic, in an attempt to guide the case in the right direction."

Everyone in the audience listened attentively.

Xi Luli stood up and asked, "Can I hear the teacher's opinion?"

Zeng Li asked him to sit down.

"Starting right from the most special place, the asshole."

"A common possibility is that the murderer originally had a normal sexual orientation and was sexually assaulted for a long time, which led to the gradual loss of normal erectile function."

"There is a fear of sex, so the victim has no signs of sexual assault."

"He can kill people, so how can he be passive?"

"Also, caring about whether his asshole is clean or not, does this behavior mean that his asshole can't be kept clean for a long time? Doesn't it also indirectly indicate that he has no freedom or conditions?"

"My inclination is that the perpetrator had been in prison, sexually assaulted by someone of the same sex for a long time, and had recently been released. The victim's access to the perpetrator was through prostitution. The perpetrator had no other injuries other than their nails being pulled out, and no signs of drugging. This suggests they were willingly in a separate space, which gave the perpetrator the opportunity to control them."

Zeng Li pointed to the key points she had written on the blackboard and explained them one by one.

"Now use the known valid information to speculate on the murderer's situation."

"They were released in the last three months or so. They are locals with obvious psychological disorders, possibly manifesting as mysophobia. They have to wash their hands after doing anything. This has caused eczema on their hands for a long time. They don't have a partner, are cowardly, short in stature, and live alone."
