OSAKA -- A 61-year-old man suspected by police of setting the fire that killed 25 people at a psychiatric clinic in Osaka in December has died in hospital.

The Osaka Prefectural Police Department believes Morio Tanimoto was well prepared for the arson attack and his suicide, in which many others were caught up. Such an event has been called "extended suicide" and this one has things in common with previous acts of murder.
