LUDINGTON, Mich. (AP) -- A jury in Ludington has found a man guilty of first-degree murder in the killing a Michigan state trooper during a traffic stop.
20 year-old Eric Knysz of Irons was on trial in the September shooting of 43-year-old Trooper Paul Butterfield II in Mason County.
A jury got the case Tuesday and took about two hours to convict him on the murder and other charges.
Authorities say Knysz had stolen guns with him when Butterfield pulled over his pickup truck. Knysz's wife Sarah testified against him.
In closing arguments Tuesday, Prosecutor Paul Spaniola said the evidence is clear that Knysz is guilty.
Defense lawyer David Glancy says the only witness placing Knysz in the pickup that day is his wife, who benefited from a plea deal.
