Law enforcement authorities in Florida say they have found the body of one of the two missing University of South Florida doctoral students on a bridge over Tampa Bay, and a roommate has been taken into custody. Hillsborough County Sheriff Chad Chronister said Zamil Limon’s remains were found on the Howard Franklin bridge Friday morning, but Nahida Bristy is still missing. He said Limon’s roommate faces several charges including domestic violence and unlawfully moving a body. The couple from Bangladesh disappeared from campus on April 16.
