MANISTEE, Mich. (WOOD) - A man and woman already charged in connection with the death of Michigan State Police Trooper Paul Butterfield are now facing additional related charges in another county.
Eric Knysz and his wife Sarah were arraigned Tuesday in Manistee County District Court.
Eric Knysz, 19, was charged with receiving and concealing a stolen firearm, carrying a concealed weapon and assault with a dangerous weapon.
Sarah Knysz, 20, was charged with unlawful driving away of a vehicle.
The charges in Manistee County are related to what police say happened after Eric Knysz shot Butterfield, 43, during a traffic stop in Mason County on Sept. 9.
The Knyszes allegedly drove off from the scene of the shooting and switched out their truck with a white sedan that they allegedly stole after test driving it.
About two hours after the shooting, Michigan State Police troopers caught up with the couple in Manistee County at the Dublin General Store gas station.
Gunfire was then exchanged between Eric Knysz and the troopers, and the 19-year-old was shot in the knee.
Both Eric and Sarah Knysz were taken into custody. Eric Knysz was taken to a hospital in Traverse City where he underwent surgery for the gunshot wound and his wife was taken to the Mason County Jail.
Two days later, Sarah Knysz was arraigned in Mason County on charges of being an accessory after the fact and auto theft.
Eric Knysz was then arraigned several days after his wife in Mason County on charges of murder of a police officer, felony firearms, carrying a concealed weapon, auto theft and being a second-time offender.
Both Eric and Sarah Knysz are expected back in court in Mason County on Oct. 11.
Police are offering up to $20,000 in rewards for information leading to convictions.
