OSAKA — Mamoru Takuma, the suspect in the primary school rampage that claimed the lives of eight pupils in Osaka Prefecture, is suspected by psychiatrists of having paranoid personality disorder, it was revealed Tuesday.

In a previous incident, however, Takuma was diagnosed with schizophrenia, the Japanese Association of Psychiatric Hospitals said.

In general, schizophrenics are not considered criminally responsible for their actions and are not supposed to face charges. People with personality disorders, however, can be found partially responsible for criminal acts.
