Health Department spokeswoman Dara Chadwick says the body of 22-year-old Sunil Tripathi was identified Thursday morning through a forensic dental exam.
Relatives of the Bryn Mawr, Pa., man have been searching for him. Both the FBI and Brown students have helped.
After the FBI released photos of two men suspected in the marathon bombings, someone speculated online that one of them looked like Sunil Tripathi, the 22-year-old Brown University student from Radnor who has been missing for more than a month.
New video has now been located that shows a man who could be Sunil Tripathi.
Brown University says the search for a missing student who was last seen on campus a week ago is now expanding outside Providence to Philadelphia, Boston, Connecticut and New York.
