Matthew Chase Whitmer, 20, of Hercules, California, was last seen at home in the early morning hours of November 15, 2007. His family said he had a long history of mental health struggles, including schizophrenia and prior suicide attempts, and that he had stopped taking prescribed psychotropic medications before he left home sometime before 6:30 a.m.

Matthew’s car was later located parked near the Golden Gate Bridge in San Francisco with his wallet, identification, and wet clothes inside. Two witnesses reported seeing a young man jump from the bridge at about 6:25 a.m., and a text Matthew sent to a friend at 6:23 a.m. reading Peace out is consistent with a possible suicide. Authorities searched after the jump was reported, but his body was never recovered.

Matthew’s family has since advocated for stronger suicide-prevention measures at the bridge. Does anyone have information about Matthew’s last movements or who he might have been with on the morning of November 15, 2007?
