Joseph Edward Doerfler was a 24-year-old Air Force airman who failed to report for duty at Luke Air Force Base in Glendale, Arizona, on March 16, 1981. He was described as a White male, 6 feet 1 inch tall, about 196 pounds, with brown hair and brown eyes. His unexplained absence began the long-running missing person investigation that remains open.

The Air Force Office of Special Investigations classified him as missing, and no publicly detailed signs of foul play or clear motive for leaving have been reported.

What information might help clarify where Joseph went or what happened to him on March 16, 1981?
