Police found a bag inside his car containing knives and other sharp-edged tools, and the seats were covered in blood. The identities of most of the victims have not been revealed at the requests of their families — a reflection, critics say, of the stigma and shame people with disabilities still suffer in Japan. At the time, the Sagamihara attack was the worst mass killing in Japan since the second world war. A man accused of killing 19 residents at a care home in Japan for people with disabilities has pleaded not guilty, with his lawyers claiming that he was suffering from a psychiatric disorder at the time of the attack. He then drove to the nearest police station to hand himself in. A verdict is expected on 16 March. Police believe the year-old, described by neighbours as polite and helpful, was motivated by a deep-seated hatred of people with disabilities. An arson attack on an anime studio in Kyoto last July killed 36 people.
