Jury finds Eric Knysz guilty of killing Trooper Butterfield

LUDINGTON, Mich. (WZZM/AP) -- A Mason County jury 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 for the September 9, 2013 shooting of 43-year-old Trooper Paul Butterfield II in.

A jury got the case Tuesday and took about two hours to convict him on of all four counts, including murder of a peace officer, stealing a car, and two weapons charges.

Authorities say Knysz had stolen guns with him when Butterfield pulled over his pickup truck. Knysz's wife Sarah testified against him.

Butterfield's fiancee Jen Sielski tells the Ludington Daily News that justice was service but it doesn't bring Butterfield back.

Defense lawyer David Glancy says the only witness placing Knysz in the pickup that day is his wife, who benefited from a plea deal.


LUDINGTON, Mich. (WZZM) -- A jury is deliberating the fate of Eric Knysz, the man charged with killing Michigan State Trooper Paul Butterfield in September.

20-year-old Knysz is charged with the murder of a peace officer, stealing a car, and two weapons charges.

The jury got this case at 3:45 p.m Tuesday. During closing arguments Mason County Prosecuting Attorney Paul Spaniola told the jury he met the burden of proof. During the week of testimony, he providing fingerprints, two confessions by Knysz, Sarah Knysz' eyewitness account, and testimony from two friends of Knysz who told police Knysz admitted he had shot a cop and wanted to buy marijuana.

The jury returned to the courtroom Tuesday afternoon and asked to see a map that was presented but was never entered into evidence. It was not entered into evidence because some material could be considered objectionable, Mason County Prosecuting Attorney Paul Spaniola said. The map was redacted, according to the Ludington Daily News.

Tuesday afternoon the courtroom was filled with police and relatives of Trooper Butterfield. WZZM 13's Jon Mills has been following this case since day one. You can follow his tweets from the courtroom below:
