(CBS/AP) PROVIDENCE, R.I. - The FBI is helping Providence police in the search for a missing Brown University student who disappeared earlier this month.
Spokesman Gregory Comcowich said Sunday that federal law enforcement officials were aiding the search for 22-year-old Sunil Tripathi, who was last seen in the campus area on March 15.
Sangeeta Tripathi, the student's sister, told the Providence Journal that his wallet, ID cards, credit cards and cell phone were found in his room.
Sunil Tripathi is a philosophy major at Brown who grew up in Bryn Mawr, Pa. He was living in Providence since 2008 and was on approved leave from the Ivy League school.
The search expanded outside Providence to Boston, Connecticut, New York and Philadelphia.
