Only three months had passed since the seemingly happy couple Donnah and Mark Winger, adopted their first child when Mark Winger told the 911 operator that he'd shot a man who was killing his wife with a hammer. More than three years after Donnah's murder, her best friend DeAnn Schultz came forward to say that she'd had an affair with Winger before her friend's killing that police began to look deeper into the case.
