Summary based on the NamUs case record (MP11806) and 2 other sources
Dominic Alderson, a 27-year-old man from San Rafael, California, was last seen on March 16, 1985. A witness reportedly observed someone matching Alderson's description jump from the Golden Gate Bridge. Two days later, on March 18, 1985, authorities found his vehicle and personal belongings abandoned at the Vista Point near the bridge. Despite this discovery, Dominic's body was never recovered, and no additional evidence has emerged to conclusively explain his disappearance.

The case remains open, and it is suspected that Alderson may have died by suicide, given the circumstances. His disappearance is documented in several missing persons databases, but no further leads have surfaced in the years since his last sighting.
Last Seen: Mar 16, 1985
