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 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.

Docotrs are currently working to see if his organs can be donated.

Knysz is serving a life sentence for killing Butterfield during a traffic stop last September in Mason County.

Prosecutors said Knysz had stolen guns with him when Butterfield pulled over his pickup truck in the west-central Michigan county. Defense attorney David Glancy argued during trial that the only witness who could place Knysz in the pickup that day was his wife, Sarah, who testified against him.

She received a sentence of two to five years in prison as an accessory after the fact.  

The shooting happened near Ludington, in Mason County. Investigators say Butterfield stopped a vehicle and then was shot in the head.

He was taken to a nearby hospital, where he later died at Munson Medical Center in Traverse City during emergency surgery.

Two hours later, police found the two suspects at a gas station in the town of Wellston. When police approached them, Eric Knysz pointed a gun at the officers.

Police shot Eric Knysz, who was taken to a hospital with non-life-threatening injuries. Eric Knysz faces a homicide charge, murder of a police officer and other felonies. His trial is set to begin Feb. 18 in Mason County Circuit Court.

Butterfield is a 1988 graduate of Bridgeport High School and was a 1987 Class A State Cross Country Champion.

Butterfield had been with the MSP for 14 years and worked at the MSP detachment in Hart. He was a veteran of the U.S. Army and had recently become engaged to be married.
