Mark Hamilton Smith, 39, was last seen at his father’s home at 2529 Debra Drive in Springfield, Oregon, on March 1, 1992. He was described as having blue eyes and a moustache or beard. The Lane County Sheriff’s Office handled the investigation, but the circumstances of his last known moments are sparse and the case went cold.

No details are available about what he was wearing, whether he had personal belongings with him, or any witnesses to his disappearance. His father, Claude Robert Smith, has since died; any insights he may have had are no longer available. The official missing persons report was not filed until June 2, 2014, more than two decades after he was last seen.

Does anyone who lived in Springfield in 1992 or who knew Mark or his family have information that could help fill the gaps in this case?
