ORANGE CITY—A Spirit Lake man accused of killing his friend after a night of drinking in an Ireton farmhouse is once again a free man.

A $10,000 cash bond was posted for Gregg Eugene Winterfeld on Nov. 17 by his sister, Janine Sonichsen of Sioux City. Winterfeld faces first-degree murder charges in the death of Grant “Willy” Wayne Wilson of Cleghorn.

Winterfeld’s bond originally was set at $100,000; however, during a Nov. 17 hearing 3rd District Judge Patrick Tott agreed the 71-year-old could post 10 percent of the bond in cash.

He also must remain on pretrial supervision from the Iowa Department of Correction Services and agree to electronic monitoring.

Tott denied a May request from Winterfeld’s attorneys to lower his bond to $50,000, calling it “inadequate “regarding the seriousness of the offense and that violence was involved.”

Winterfeld had been held in the Sioux County Jail in Orange City since May 9, the day of the shooting.

During that incident, Winterfeld allegedly drew a Ruger .22-caliber revolver and shot the 58-year-old Wilson in the forehead after the two spent the day drinking beer and whiskey together at Winterfeld’s mother’s rural Ireton property where he resides part-time.

The two men got into an argument and Wilson decided to sleep in his car parked outside of the residence rather than inside the house, according to the search warrant application.

After arming himself with the revolver, Winterfeld went to the car and convinced Wilson to come back into the house. However, they started to argue again once he re-entered and when Wilson tried to leave the house Winterfeld drew his firearm which caused Wilson to turn around.

Winterfeld said Wilson had a “crazy look” in eyes so he shot him near his right eye from a distance of three to four feet away.

Initially, Winterfeld told a deputy Wilson pulled a knife on him, then said it was a cellphone before saying Wilson gave him “a look” before he shot him. A folded up pocketknife was found in Wilson’s pants pocket.

The deputy who interviewed Winterfeld said, in his experience, drawing a firearm during a verbal altercation before “the look” took place was inconsistent with a self-defense claim and was an unjustified use of force.

Winterfeld told authorities the source of the argument was that Wilson thought there was a romantic relationship between Winterfeld and a woman present during the shooting.
