The son of a victim in an abduction case involving the Aum Shinrikyo doomsday cult wants perpetrators to continue feeling remorse 30 years on.

"There are two kinds of atonement," said Minoru Kariya, 65, whose father, Kiyoshi, then 68, was killed in the incident. "One is criminal punishment for breaking the law and the other is compensation to victims."

In February 1995, Kiyoshi was abducted on a street in Tokyo by senior cult members seeking information about the whereabouts of his younger sister. Then-Aum Shinrikyo leader Chizuo Matsumoto, who went by the name of Shoko Asahara, had ordered the abduction so that Kiyoshi's sister, who was a follower of the cult, would make a large donation to it.
