This is doubtful. When the school informed her mother, she was called to a hotel a few kilometers away from the school to tell her that she was also prevented from leaving. This practice is also very puzzling. It is reported that on the day of the incident, the counselor called the student's mother and asked her if she was with her son. The mother said that she had separated from her son, and the counselor immediately hung up. Does this mean that the counselor knows something? At that time, the student's mobile phone was broken because of falling from the building. After the repair, he can't see any traceable information of the mobile phone. It seems that it should have been deleted long ago.
From these things, we can see that the case itself is full of doubts, and the reason why the students jumped from the sixth floor has become a mystery. The incident itself is really strange, and there is no causal relationship. After investigation by the police, only a tall building fell, excluding others from committing crimes. This is incredible.
In short, I think this case is still very strange, the cause is unknown, and some points after the incident simply don't make sense, but I can't find the real reason. A person who was still writing a study plan that day could jump off a building like this without warning. Is it because he was beheaded? Such a thing is really scary.
