Carroll Eugene Streich, known to some as Sonny, was 41 when he was last seen at Nellis Air Force Base in Clark County, Nevada. The official last-contact date is June 1, 1972. He was a U.S. Air Force veteran of the Vietnam War, originally from Wisconsin and one of eleven siblings. At the time he disappeared he was described as a Caucasian male, 5 feet 9 inches tall, about 190 pounds, with brown hair and blue eyes.

Details about the day he vanished are sparse and reports conflict about what led up to his disappearance. Family accounts indicate he may have gone AWOL once before in 1969 and questions remain about whether the military treated the 1972 absence as AWOL or as a missing person case. The Air Force Office of Special Investigations is handling the inquiry, and over time relatives’ obituaries have listed him as deceased, reflecting the family’s painful acceptance. Few concrete facts about his last movements are known.

If anyone knew Carroll, served with him at Nellis, or has information about his whereabouts in 1972, please come forward with what you remember.
