Prosecutors charged Jack Lang of Oak Creek with first-degree intentional homicide Thursday.
Authorities say Lang called 911 on Wednesday to say he'd just shot his wife in the face. Police found June Lang dead near the bed.
Jack Lang told investigators she nagged him and wouldn't shut up, and even though he loved her he'd had enough. He says she criticized him for not being able to help as much with housework.
He says he got his .22 caliber gun and warned her he was holding it inches from her head but she didn't believe him.
Online court records didn't immediately list a defense attorney.
