Last month, a first-year student living in a dormitory at a special purpose high school committed suicide. Before this incident, there were several danger signals, including self-harm, but it turned out that the school did not take any action despite knowing it.

Reporter Ha Jeong-yeon reports.

<Reporter> On the

27th of last month, Lee took his own life.

I was able to hear from my friends and seniors why my son, who was living in a dormitory, died suddenly.

[Lee's mother: There are a lot of messages. Actually, it was hard for ○○ like this, it was hard because of someone, something happened. When I put it all together, it all came together.] Due to a

minor misunderstanding, a friend's sniping article about his son was posted on SNS, and the rumors spread out of control like the truth.

I kept getting messages saying "I'm so sorry" and "I'm sorry for not being able to help".

[Lee's mother: He swears softly, and the seniors also told me that while I was talking, he came and took his friend and made him feel uncomfortable and brought tears to his eyes.] What's

even more unfortunate is that there were enough opportunities to prevent the tragedy.

The son even tried to harm himself due to the pain, but the teacher did not take any action after hearing this.

[Lee's father: There were several autographs, which may not have missed our child.

A child's suffering started from his classmates or friends, but the responsibility of the adults who did not manage it properly lies within it.

It's too much of a pity if I had informed the parents at least once.] The

day before the extreme choice, the homeroom teacher and my son even had a meeting.

But no one told the parents the story.

The school explained that they checked the student's condition, but did not intervene because no psychological anxiety or injuries were found.

[Gangwon-do Office of Education official: If there is a problem with school operation or such things, it will be audited, but for now, a story to be discussed after the procedure is conducted…

.] More

than 320,000 people have signed a petition asking for a thorough investigation into the facts of this case.
