An arraignment hearing has been delayed for a man accused of fatally shooting a Michigan state trooper.
Mason County District Court Magistrate Patricia Baker says Eric Knysz is having more surgery and won't be arraigned on Thursday.
The 19-year-old is under police guard at Munson Medical Center in Traverse City, where he's recovering from a gunshot wound he sustained before his arrest on Monday.
Knysz is charged with first-degree murder in the death of Trooper Paul Butterfield, who was shot in the head during a traffic stop Monday in Sherman Township, about 80 miles north of Grand Rapids.
Twenty-year-old Sarah Knysz is charged with helping her husband try to escape. WOOD-TV out of Grand Rapids is reporting that Sarah is from Shiawassee County. There's no indication that either has a lawyer.
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.
Butterfield's funeral is Saturday at Manistee High School. Visitation is scheduled for Saturday, Sept. 14, between 10 a.m. and 1 p.m. at the high school on 12th Street in Manistee. The funeral will follow immediately with no procession or graveside service.
