After overhearing that Mike is flying to Las Vegas that night, Margaret waits for him at the airport. She says that she's been so worried about the police that she has withdrawn her entire life savings, and pleads to start a new life with him. They go to a restricted and deserted baggage handling area where Mike realizes he's being tricked when she lets it slip that she stole his pocket knife, something she wouldn't have known if she hadn't overheard their discussion of the con. He says that he cannot return her money because it has already been divided. Margaret, however, produces Billy's gun and demands that he beg for his life. Mike refuses, thinking that he is calling her bluff, but Margaret shoots him in the leg. When Mike curses her, she shoots him five more times, killing him. She calmly conceals the gun and walks away.
