Besides involvement in Tokyo subway sarin gas attack and LSD drug affair, Hayashi was convicted in a number of other crimes.
[3] Previously Hayashi helped another Aum member to recover from a forced drug treatment administered by the follower's father (also to prevent him from becoming a renunciate).
Hayashi, wearing a surgical mask of the type commonly worn by Japanese during cold and flu season, boarded the southwestbound 7:48 a.m. Chiyoda line train number A725K on the first car.
Two transit authority staff in the subway were killed by the sarin, including the assistant station-master, and 231 suffered serious injuries.
Niimi, citing different reasons (loyalty to Asahara and Buddhist fatalistic ideas), also said that he would "gladly" accept the capital punishment.
