NILES, Mich. (WWJ/AP) – A man accused of stabbing four people on an Amtrak train in southwestern Michigan is scheduled for trial in November.

Dates were set Tuesday during a hearing for Michael D. Williams. A judge ruled in March that he was mentally incompetent for trial, but he was found competent earlier this month after receiving medications and treatment.

Police say the Saginaw man told them he started the attack Dec. 5 after seeing a man on the train turn into a demon. The train, which had 172 passengers, began in Chicago and was bound for Port Huron. He’s accused of stabbing a conductor and three fellow passengers when the train stopped in Niles, about 10 miles north of South Bend, Indiana.

Police rushed to the train and subdued Williams with a stun gun.
