Roy Dick Ayagalria, 19, was last seen on December 16, 1978, at Bethel High School in Bethel, Alaska. Described as American Indian / Alaska Native with black hair and brown eyes, he was 5 feet 3 inches and about 115–120 pounds. He told others he intended to walk to the nearby village of Napakiak and was reported wearing a blue coat, blue jeans, and blue tennis shoes—thin clothing for December in that region.

The Alaska State Troopers opened an investigation (case number F78003189). No witnesses or physical evidence have been found and no trace of Roy has ever been located. His fate after leaving the high school remains unknown.

If anyone remembers Roy, his route between Bethel and Napakiak, or saw someone matching his description on December 16, 1978, please come forward with information.
