This further fueled the speculation that it was someone they had bullied before coming back for revenge.

Therefore, the police station later shifted its investigation focus to these individuals.

Suddenly, everyone in the school was on edge, especially the lackeys who had previously followed Li Yuanyuan, who were terrified that they would also be retaliated against.

Before they could even investigate, a fourth victim appeared.

This time it was a male student named Meng Jing, a boy who was excellent in every way. He died in full view of everyone.

It is said that during class that morning, Meng Jing's deskmate noticed that he seemed a bit listless. After asking him, he said that he was a little sleepy and eventually couldn't resist falling asleep on his seat.

At first, his deskmate didn't pay attention, thinking he was just tired. But after class, he found that Meng Jing was still not awake and thought he was sick, so he shook him. As a result, he fell to the ground and foamed at the mouth.

The classmate was terrified and quickly called the other classmates over to see.

Finally, the teacher noticed and took him to the hospital, but it was too late; he had already stopped breathing when he arrived.

The forensic examination determined that he likely died from an overdose of sleeping pills.

Preliminary investigations suggest the sleeping pills may have been placed in his water glass.

As for who put it there and when, no one knows.

No evidence has been found so far.

It was when the fourth person died that the police station realized the seriousness of the situation, and the case was transferred to the city's criminal investigation team.

After the criminal investigation team took over the case, they began to investigate the connection between the four victims. If the murderer was indeed the same person, then there must be a connection between them.

However, the investigation revealed that the group had no other connection besides being in the same high school. As for enemies, the second and third victims were the only ones with the most enemies. The other two had very good opinions of them and did not seem like bad people.

However, before they could investigate, a fifth person died.

However, the death of the fifth person was somewhat unexpected, because the murderer who killed her had already been caught.

The fifth victim was Zhou Xue, also a female teacher at the school. She was 23 years old and unmarried.

Her death was somewhat dishonorable; she died in the home of a mentally challenged man nearby.

The idiot is an old bachelor, 40 years old this year. He has no family and is not married. He is a well-known idiot bachelor in the neighborhood.

But this person isn't completely stupid; he's very strong and has a decent job.

Yes, that's right. This fool actually has a legitimate job in Beijing, and he's a full-time employee.

How can a fool have a job?

It was a job his father passed down to him—a coal mine moving job that didn't require much brainpower, just strength.

The fool was strong but not very smart. Before his father passed away, he was afraid that his son would be bullied and knew that he probably wouldn't be able to find a wife. So he made a deal with the factory that his wages would be converted into food coupons so that he could eat whatever he wanted at the factory, as long as he was full.

The factory agreed, since although the simpleton wasn't very bright, he was quite strong and wouldn't cause trouble. Besides, he wouldn't earn more than twenty yuan a month no matter how much he ate, so they agreed.

So, not only did this fool not starve to death all these years, he also grew into a tall and strong man. In addition, there were several of his father's old colleagues in the factory who took care of him and didn't let him be bullied.

So the idiot has been living a pretty comfortable life all these years.
