John Scott Holt was 28 when he was last seen at his San Francisco home on February 10, 1983. He was reported to be 5 feet 10 inches tall, about 165 pounds, with brown hair, green eyes and a scar on his forehead running from his eyebrow to his hairline. At the time he vanished he was wearing maroon sweatpants and a gold religious medal on a gold chain.

Very few clues came from the disappearance and there is no clear evidence of foul play or indication of where he may have gone. Authorities have preserved dental records, fingerprints and DNA in case of future identification, but the case remains unsolved.

Does anyone who knew John or lived in his neighborhood in 1983 have any recollection that could help investigators?
