Convicted killer Eric Knysz taken off life-support

      Officials have announced that a man serving a life sentence in the slaying of a state trooper has been taken off life-support following a suicide attempt.

      The Department of Corrections says in a release that Eric Knysz was removed from life-support about 10:30 a.m. Thursday at a hospital in Jackson.

      Knysz tried to hang himself with a bed sheet Monday afternoon at a detention center in Jackson.

      He was convicted of first-degree murder in the fatal shooting of Trooper Paul Butterfield II and was sentenced April 8 to life in prison without the possibility of parole.

      Authorities said Knysz had stolen guns with him when Butterfield pulled him over in western Michigan.
