Robert Sidney Long, 55, was last seen by his parents in the late afternoon of September 18, 2011, in Richmond, Virginia. When he stopped communicating, his family reported him missing to the Richmond City Police Department on September 24, 2011. He is described as a white male, about 5 feet 10 inches to 5 feet 11 inches tall, 150 to 165 pounds, with brown hair and blue eyes. His green 1999 Honda Civic Del Sol was also missing and is believed to be the vehicle he may have been driving.

The case drew early concern because Robert left behind necessary medication. He had a history of addiction but had completed a rehabilitation program and faced literacy challenges; his family speculated he might have become homeless and could have been panhandling. Volunteer search teams have conducted sonar sweeps of local waterways looking for his car, but those efforts did not locate Robert or the vehicle. Little else is publicly known about his movements after that visit with his parents.

If anyone saw Robert, his Civic Del Sol, or has information about where he might have gone after September 18, 2011, please come forward.
