According to a report by 'Jeju Sori,' 'A' was investigated by the prosecution for charges of sexual abuse and was handed over to the court. 

'A' had remarried the now-deceased 'B', a child care center director, back in April of 2012. The molestation allegedly began in the following year. 'A' allegedly sexually abused his 8-year-old stepdaughter, 'C', a total of ten times in the residential top half of his wife's child care center. 

After prosecution discovered that 'A' was possibly molesting his stepdaughter, they booked him without detention this past August 21. Subsequent the investigation by prosecution, 'A' was said to have hired a lawyer and was preparing for his upcoming trial. 

However, around a month ahead of his court date, 'A' reportedly used a lethal weapon to murder not only 'B' and 'C' but also 'C's brother, then took his own life by hanging himself.
