Summary based on the NamUs case record (MP90075) and 1 other source
Robert Canon, 52, was last seen on October 9, 2011, at the East Pleasanton BART station in Pleasanton, California. He had visited the San Francisco Bay Area with a friend for a convention and was supposed to take a BART train to the San Francisco airport for a flight back to Oklahoma. However, Canon never boarded his flight. Shortly after, his backpack, containing his cell phone and laptop, was found on the Golden Gate Bridge, though his clothing bag was never recovered. Investigators confirmed that he was on the bridge but was not seen exiting. Delta Airlines also confirmed that he never checked in for his flight.

Canon’s case remains unsolved, and authorities have not ruled out the possibility of foul play. Despite extensive searches and investigations, no additional information has surfaced regarding his whereabouts since that day.
