David Stephen Papageorgiou, 52, disappeared from San Bruno, California, on December 25, 2006. That afternoon, at about 3:45 p.m., he argued with family members and left the residence. He was last seen driving a green 1987 Jaguar and was not heard from again.

Papageorgiou’s Jaguar was later found abandoned in the east parking lot at the south end of the Golden Gate Bridge. Relatives said he sometimes drove near the airport to watch airplanes and spent time by the shore. Although his body has never been recovered, a death certificate was later issued and an obituary published in 2007 listed his survivors as his wife, three children, and two grandchildren. Author John Bateson includes Papageorgiou in a list of people who died by suicide from the bridge. The San Bruno Police Department investigated the case.

Did anyone in the area on December 25, 2006, notice Papageorgiou’s car at the bridge or recall seeing him that afternoon?
