JACKSON, Mich. (AP) - Officials have announced that a man serving a life sentence for slaying a state trooper was taken off life-support following a suicide attempt.

The Corrections department says in a release that Eric Knysz (NIZE) 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.

Butterfield’s father, Paul, said Thursday that Knysz was a “very troubled individual.” He said Knysz‘ death “didn’t bring” his son back.
