ORANGE CITY—A 71-year-old Spirit Lake man has been sentenced to 50 years in prison for a shooting death last year in rural Ireton

The sentencing of Gregg Eugene Winterfeld for second-degree murder was handed down Monday, Nov. 8, by Judge Jeffrey Neary in Sioux County District Court in Orange City.

Winterfeld also was ordered to pay $150,000 in restitution to the estate or heirs of 58-year-old Grant “Willy” Wayne Wilson of Cleghorn.

The case against Winterfeld arose following the shooting death of Wilson on May 9, 2020.

Wilson spent the afternoon and evening of that Saturday visiting Winterfeld at the rural Ireton home of Winterfeld’s mother.

The two men spent much of the day drinking alcohol, according to Sioux County attorney Thomas Kunstle, who prosecuted the case on behalf of the state of Iowa in cooperation with the Sioux County Sheriff’s Office.

They eventually got into an argument and Winterfeld pulled out a Ruger .22-caliber revolver and shot Wilson in the head.

Winterfeld initially faced a charge of first-degree murder, a Class A felony, in a trial held March 30-April 7 in Sioux County District Court.

The jury, however, found him guilty of second-degree murder. The verdict indicated the jury did not think Winterfeld’s action was premeditated, although the jury did affirm he used a dangerous weapon.

Before sentencing on May 28, Neary noted the law grants 10, as opposed to six, peremptory challenges to the state and defendant during the jury selection process for a Class A felony trial.

He ordered a new trial and released Winterfeld on bond.

Retrial began on Oct. 5 and on Oct. 12, a second jury returned a guilty verdict of second-degree murder.
