Human remains found Sunday during the search for a missing University of South Florida doctoral student were confirmed as belonging to Nahida Bristy, the Hillsborough County Sheriff's Office said.

The remains of Zamil Limon, who family members have said previously dated Bristy and who was also a doctoral student, were found last week.

Hisham Abugharbieh, Limon's roommate, has been charged with first-degree murder in both deaths.
