A 19-year-old St. John's student who had been missing since January 20 was reunited with her family yesterday. Erica Desai was last seen by a cousin who dropped her off at a dorm, and her family worried that something might have happened to her. A surveillance tape seemed to show a woman of Indian descent using her ATM card, raising questions whether she was missing or AWOL. Now, NY1 reports that Desai "called police late last night after seeing herself on television...Police say she was embarrassed about being expelled from school" for using someone else's credit card "...They also say she's been riding the trains for days." Desai initially told police she was abducted, but then admitted to running away.
