Oakland is teeming with college students on any given day as students from Carnegie Mellon, Pitt and Carlow cross back and forth between traffic as they go to and from classes.
Andrew Karis was a student at Carnegie Mellon University in 1993, when he disappeared on a March day. Suddenly, he was missing from those crowds of students.
Also known by the nicknames Andy, Drew and Sparky, he was last seen on campus on March 1 that year. When he was reported missing, authorities tracked his credit card and telephone records, and determined that he might have purchased a Greyhound bus ticket to New York City.
He was 19 years old at the time of his disappearance and would be 39 years old today. Andrew is described as a white male about 5 feet, 8 inches tall; 130 pounds; and with brown hair and hazel eyes.
Investigators believe he might have been in San Francisco on March 14, 1995. But since that date, no one has seen or heard from him.
Authorities feel he disappeared under suspicious circumstances.
Anyone with information concerning this case is asked to contact the San Francisco Police Department at 415-553-0123.
