Andrew Karis was a 19-year-old junior in Electrical Engineering at Carnegie Mellon University when he vanished from Pittsburgh. He was last seen on campus on March 1, 1993. Known to friends and family as Andy, Drew, or Sparky, he was described as a perfectionist and private, with a small circle of friends.

Investigators traced electronic activity that suggested a trip east. Andrew may have bought a Greyhound ticket to New York City on March 2; his credit card was used at a Manhattan hotel and his ATM card, requiring his PIN, was used in the city through March 6. On March 14 he phoned his mother in San Francisco from an unknown location, sounding distraught and asking her to pick him up at 3rd and Geary. She searched intersections named 3rd Street and 3rd Avenue where they cross Geary but did not find him.

At his Pittsburgh dorm his mother found a note listing George Washington Bridge, Half Dome, Golden Gate Bridge, which raised concerns he might have been contemplating suicide. There has been no activity on his bank accounts or Social Security number since March 1993 and the circumstances are considered suspicious. Did anyone in New York or San Francisco see Andrew around early to mid March 1993?
