SIOUX COUNTY, Iowa (KCAU) – A Spirit Lake man has been found guilty of the May 2020 murder of an Ireton man.
On Wednesday, Gregg Winterfeld was found guilty of the second-degree murder of Grant Wilson, 58, of Ireton. He was originally charged with first-degree murder.
On May 9, around 10 p.m., the Sioux County Sheriff’s Office responded to a report of a disturbance involving a shooting at a residence three miles northwest of Ireton.
Officials arrived at the home and found Wilson dead inside with an apparent gunshot wound.
According to court documents, the shooting stemmed from an argument between the two men after they had been drinking whiskey and beer earlier in the day.
Authorities said Wilson decided to sleep in a car that was parking in the driveway, and Winterfeld locked the doors to the house, put on a holster with a loaded revolver, exited the residence, and convinced Wilson to come back inside.
When both men reentered the house, the argument continued, and Wilson attempted to leave when Winterfeld pursued and un-holstered the gun.
Authorities said Wilson turned around and, according to Winterfeld, gave him a look, so he raised the gun and aimed it as close as he could get to Wilson’s forehead, shot and killed him.
The Sioux County District Court has yet to schedule a sentencing date.
