Hye Min Choi, 19, who also goes by Joseph, was set to board the flight home to North Carolina after finishing up his first year in Urbana, but his family was shocked when hours later he did not deplane with the other passengers.
Security footage depicts Choi passing through the checkpoint at O'Hare Saturday at 3:10 p.m. Family last heard from him just before 5 p.m., when Choi's father recalls him saying that he was hungry at the airport. His father urged him to get something to eat—but the rest is a mystery.
Choi's luggage arrived in Greensboro, with no sign of the engineering major whose family had planned him a birthday party for the next day.
Choi turned 19 Sunday.
Anyone with information on Choi's whereabouts should call the Chicago Police department at 312-744-8266.
