A man who stabbed four people in a downtown Columbus office building last year has been declared not guilty by reason of insanity.

It’s never been a question of whether or not John Mallett carried several knifes into the lobby of Miami Jacobs Career College and went on a stabbing spree.

But a Franklin County judge today sided with two court psychologists who said Mallett’s severe mental illness kept him from understanding his actions. He’s been committed to a maximum security wing of a West Columbus mental hospital.

Mallett faced multiple charges of attempted murder and felonious assault. He had no known connections to the college or his victims.
