Russell Stiffler, 90, was arrested after he allegedly punched a state trooper who was called to his Armagh, Pennsylvania, home to check on the welfare of his wife Jane Stiffler.
Jane's daughter, Mildred Smith, said that Russell wouldn't let her talk to her mother, so she called police and asked for a welfare check.
Smith recently suffered a stroke and said she was trying to notify her mother of her medical condition, but her calls to the home were hung up.
"He's being arrogant," Smith told WTAE-TV. "He's dangerous. It's the way he is. He's the type of person, 'I can do this, I can do that.'"
According to the Associated Press, Russell threatened to shoot any troopers or medical personnel who came to his home after police were asked to check on his wife just before 6 p.m. last Friday.
Police say Russell met the troopers outside and refused to show his hands, punched a trooper and was arrested. His hearing is scheduled for March 25.
