Summary based on the NamUs case record (MP29973) and 3 other sources
Joseph Anthony Stuart, aged 35, went missing on September 6, 1991, from Fullerton, California. On the day of his disappearance, he was last seen by a friend, mentioning he was headed to Reno, Nevada, to explore a potential job opportunity. Before leaving, Stuart left a note for his landlord, dated the same day, stating that he was going fishing and would return by Monday. However, Stuart never returned, and his landlord reported him missing on September 26 after not seeing him for weeks.

Upon searching his residence, the landlord found two notebooks where Stuart had written about suicidal thoughts. This raised concerns about his mental state at the time of his disappearance. Despite these clues, Stuart has not been seen or heard from since. His case remains unsolved, with no confirmed sightings or further evidence to clarify what happened to him after he was last seen. Authorities continue to investigate, but Stuart's fate remains a mystery.
Last Seen: Sep 6, 1991
