Mamoru Hase, the 70-year-old father of a boy murdered in a series of attacks on children in Kobe in?1997,?is still trying to find the truth behind the tragedy.

¡°We, the bereaved family, want to know ¡¯why¡¯ the man who committed the crime killed my son,¡± Hase said in a recent interview, ahead of the 29th anniversary on Sunday of the death of his son, Jun, at the age of 11.

¡°I haven¡¯t received any contact recently¡± from the attacker since 2004, when he was provisionally released from a medical juvenile reformatory, Hase said. The attacker committed the crime when he was 14 years old.
