Update – Stabbing on train

A man accused of stabbing four people while on an Amtrak train in southwest Michigan told police he began the attack after seeing a demon. Court documents released Monday show that 44-year-old Michael D. Williams told investigators he started stabbing people Friday night after he saw a man turn into a demon. Williams, of Saginaw, is being held on a $1 million bond. He pleaded not guilty to attempted murder charges Monday and requested a court-appointed attorney. Investigators say he stabbed a conductor and three passengers when the train stopped in Niles, near the Indiana border. Police subdued Williams with a stun gun. Police said the victims were in stable condition. Williams was riding from Chicago to Port Huron, which is 60 miles northeast of Detroit.  (AP)
