Deaths of Arnold Archambeau and Ruby Bruguier

Just before dawn on the morning of December 12, 1992, Arnold Archambeau and Ruby Bruguier, aged 20 and 18 respectively, left a car Archambeau had been driving following an accident at an intersection near Lake Andes, South Dakota, United States. They left Bruguier's 17-year-old cousin, Tracy Dion, in the car without any explanation as to where they might be going, and their whereabouts remained unknown for the next three months. One woman told police later that she had seen Archambeau at a New Year's Eve party, but their families never saw the couple, who had a young child together.
