Gregory Smith was 33 when he was last seen in Oakland, California, on December 20, 1988. He had been released from the California Department of Corrections earlier that year and disappeared after that release; no confirmed sightings or contact have been reported since.

At the time he went missing Smith was described as 5 feet 11 inches tall, 155 pounds, with brown hair. Authorities continue to list his case as unsolved and are asking for any information that might explain what happened to him.

If anyone knew Gregory, where he stayed, worked, or spent his time around 1988, can you share what you remember?
