Update – Stabbings on train

A 44-year-old man faces a hearing on charges that he stabbed three fellow Amtrak train passengers and a conductor in southwestern Michigan.  Michael Williams of Saginaw is to appear Monday in court on attempted murder charges.  Police used a Taser to subdue Williams Friday night as the train was stopped at a depot in Niles, about 10 miles north of South Bend, Indiana. He’s being held in the Berrien County Jail on a $1 million bond.  The four victims were in stable condition Sunday. Niles Police Chief Jim Millin has said Williams didn’t have a relationship with any of the victims. Millin said detectives spoke with Williams over the weekend, but the chief declined to discuss a motive behind the attack.  The train was headed to Port Huron from Chicago.  (AP)
