State police say a man stabbed two people at a home in Taunton yesterday, then crashed a car through the front of a Macy's store at the Silver City Galleria and stabbed two other people at the mall. It's unclear which victims have died.
Authorities say an off-duty law enforcement officer shot and killed the suspect.
Witnesses reported a chaotic scene.
A motive for the attacks remains under investigation. Officials say the suspect also may have been involved in an earlier car crash on the street where the first stabbings took place.
