A Canadian on trial for sexually assaulting his daughter was found not criminally responsible after a judge ruled he was in a state of automatism while sleepwalking, reports Leader-Post.

Dr. Colin Shapiro, a sleep expert, testified at trial the man was likely asleep when the assault took place, suffering from parasomnia, a type of sleep disorder that can include sleep eating, sleep walking and sleep sex, that he said can be triggered by alcohol consumption.
