Hearings postponed in shooting death of Trooper Butterfield

Sarah Knysz was held on a $250,000 bond

Key hearings have been postponed for a couple accused of crimes related to the murder of a state police trooper.

Eric and Sarah Knysz waived their right to preliminary examinations within 14 days of their Sept. 13 arraignments. The Associated Press reports the hearings were originally scheduled for Wednesday but will be rescheduled.

A preliminary exam's purpose is to determine whether there is enough evidence for a trial.

Eric Knysz faces a homicide charge, murder of a police officer, and other felonies. His wife Sarah is charged with an accessory after the fact and unlawful driving away of an automobile.

Sarah Knysz was held on a $250,000 bond while her husband was held without bond. It was also ordered that Eric may not have any contact with his wife.

The couple could also face charges in Manistee County, where they were arrested.

Trooper Paul Butterfield was shot in the head in early September during a traffic stop in Mason County. Officials say that about four minutes later, a passerby saw the trooper on the side of road and called 911 to report the officer had been shot in the head.

State Police said information Trooper Butterfield relayed to dispatch about the vehicle he stopped, helped develop a suspect in the shooting.

Police caught up with the suspects at a gas station in Wellston, in Manistee County, about two hours later. During the arrest, State Police said there was an exchange of fire and Eric Knysz was shot. He recovered at Munson Medical Center before being arraigned.
