Donald Emmanuel Butler, 59, was last seen April 22, 1979, in Irwin, a small community in Bonneville County, Idaho. He and his wife were driving west when their white 1968 Pontiac left the road and entered the Snake River in a remote area. The car was not found until July 28, 1979, when it was located in the South Fork of the Snake River about 400 yards upstream from the South Fork Lodge.

Inside the submerged vehicle authorities recovered Mrs. Butler, still buckled in her seat. Donald Butler was not in the car and an extensive search of the river and banks turned up no trace of him. He was described as a white man, 5 feet 8 to 5 feet 9 inches tall, 165 to 170 pounds, with graying hair and hazel eyes. He was believed to be wearing a light-colored Western-style shirt, light-colored pants with a black checkered pattern, and a tan Western hat.

The case remains open and Butler is listed as a missing person. His children have provided DNA samples that are on file to help identify remains if found. Does anyone have information about the area or that day that could help resolve what happened to Donald Butler?
