Sidney S. Riggs was a 22-year-old senior at Lander University who vanished from Greenwood, South Carolina. He was last seen on March 4, 2000, just before the campus spring break; his mother reported him missing about a week later when he did not return to class and could not be reached.

Investigators found his off-campus apartment undisturbed, with no signs of forced entry or a struggle. An associate said Sidney had talked about possibly traveling to Florida for the break, but that lead could not be confirmed. At the time he disappeared he was described as a white male, 5 feet 9 inches, about 155 pounds, with brown hair and blue eyes.

The circumstances remain unclear and the case is cold, though the Greenwood Police Department has periodically revisited the file and it remains open. Did anyone in Greenwood or at Lander University remember seeing Sidney around March 4, 2000, or have information about his possible travel plans?
