We shared with the fact that Kang Mo, a public service agent who handed over the victims' information to Jo Joo Bin, mocked Jo Joo Bin to kill the child. The target child was confirmed to be the child of Mr. Kang's homeroom teacher. The child's mother filed a petition with the Blue House asking her to disclose the identity of Mr. Kang, but over half a day agreed to over 300,000 people.

A child's mother A, asking for the release of Mr. Kang's identity, posted on the Blue House petition bulletin board, saying, "The past years were anxiety and fear that will not end until death."

He said that he was a homeroom teacher of Kang's past, and that he often consulted with Kang, who did not get along well with his friends.

However, Mr. Kang insisted that he was too obsessed with himself and kept the distance, and that threats began.

Kang, who dropped out of school, came looking for himself with a weapon and left a graffiti on his family's resident number and murder in the apartment hallway, and continued to threaten him by text and phone.

Mr. Kang, who couldn't stand, sued Mr. Kang, who served in prison for a year and two months and started retaliating against Mr. A since March last year.

Mr. A changed his name, cell phone number, and social security number to work place, but Mr. Kang, who served as a public service worker at the ward office immediately after leaving the office, understood Mr. A's personal information.

The threat of harming Mr. A's daughter through social media continued, and police investigation revealed that she gave Jo Joo-bin four million won to ask for Mr. A's daughter's murder.

More than 300,000 citizens agreed by today's (29th) 7 o'clock on the letter of Mr. A, ending with the words, "I want to live a normal and happy life in a safe country."
