Police on Friday searched the home of the 41-year-old man suspected of being behind the arson attack on a Kyoto Animation Co. studio that left 34 people dead.
Around 10 investigators entered Shinji Aoba's apartment in the city of Saitama at 9 a.m. seeking evidence that could help them piece together a motive and the sequence of events leading up to the crime.
They left with two cardboard boxes and speakers. Aoba was known to play loud music in his apartment, frequently creating problems with his neighbors. On one occasion, the police became involved.
