Sixty-year-old Mary Arendale of Holly Ridge, Miss., was home alone while her husband was out hunting. Hearing noises in the family's country store, Arendale armed herself and investigated. Her one-year-old poodle, Rambo, led her to a man standing on a sink in the store. When the intruder lunged at her, Arendale opened fire--killing the man. Authorities found a stolen car near the scene.
