Summary based on the NamUs case record (MP8825) and 5 other sources
Bill Neyenesch, 38, was last seen on June 2, 1983, in San Diego, California. His car was found parked at the Cabrillo Marina, where he kept his 30-foot sailboat, the *Stuffit*. Both Neyenesch and his boat were missing, and despite an extensive Coast Guard search, no traces of him or the vessel were found. At the time, Neyenesch was facing significant personal struggles, including a pending divorce and business pressures after being fired from his family’s printing company the previous year.

In the years following his disappearance, there were unconfirmed sightings of him in the Pacific Northwest and the Mission Valley area of California. Some of his loved ones believe that he may have voluntarily left his life behind. However, his whereabouts remain unknown, and he was eventually declared legally dead. His case remains unsolved, with authorities continuing to treat it as a missing person investigation.
