Here. An excerpt:
On Feb. 24, 1976, a rancher in South Dakota was installing a fence on land situated along the edge of Pine Ridge Indian Reservation when he spotted a body at the bottom of a 30-foot embankment. The badly decomposed corpse, in jeans and a maroon ski jacket, lay with knees pushed up toward chest. A coroner later determined that the woman had been dead for more than two months. The back of her head was matted with blood, and there was a single bullet wound at the base of her skull. She had been shot at close range.
