The mother of a man convicted of killing a Michigan state trooper is scheduled for sentencing after pleading no contest to a charge of being an accessory to a felony after the fact.
Tammi Lynne Spofford entered her plea in May. The plea is not an admission of guilt but is treated as such for sentencing, which is scheduled for Tuesday in Mason County Circuit Court.
The Irons resident is accused of helping her son, Eric Knysz, and his wife, Sarah Knysz, after the fatal shooting of Michigan State Police Trooper Paul Butterfield last year.
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.
Eric Knysz was found guilty in February of killing Butterfield and hanged himself in April at a detention center in Jackson. Sarah Knysz is serving 2-5 years in prison for accessory after the fact.
