MASON COUNTY, Mich. — Sarah Knysz pleaded guilty Tuesday to her involvement in the September shooting death of Michigan State Police Trooper Paul Butterfield.
In Mason County Circuit Court, Knysz, 20, admitted that she saw her husband Eric shoot Butterfield when he approached their vehicle during a Sept. 9 traffic stop.
According to the Mason County Prosecutor’s Office, she pleaded guilty as charged to being an accessory to murder after the fact and unlawful driving away of a vehicle.
Knysz said in court that Trooper Butterfield was shot by her husband before he even finished a sentence.
After the shooting, officials say she accompanied Knysz to his mother’s house, where she says he cleaned blood off the vehicle with napkins.
Officials say the two then stole a vehicle that they had test driven earlier that day before being arrested in Manistee County. Eric Knysz will go to trial for the murder in February.
