SIOUX COUNTY, Iowa (KTIV) - A Spirit Lake, Iowa, man has been found guilty in the May 2020 shooting death of an Ireton, Iowa, man.

On Wednesday, Gregg Winterfeld was found guilty of second-degree murder in the death of 58-year-old Grant Wilson. Winterfeld was originally charged with first-degree murder.

On May 9, 2020, the Sioux County Sheriff's Office responded to a shooting inside a home on Dove Avenue where they found Wilson dead.

Court documents say the two men had gotten into an argument inside the home after they had been drinking whiskey and beer since noon.

Wilson went to sleep outside in a car while Winterfeld armed himself with a revolver before trying to convince Grant to sleep inside.

Documents say the men began to argue when Winterfeld unholstered the gun and shot him.

Winterfeld said Wilson had a knife.

No sentencing date has been set.
