Roommate charged in USF murders

A tragic case involving the disappearance of two international students at the University of South Florida has ended with the arrest of their roommate.

Hisham Abugharbieh was taken into custody following an intense investigation that led authorities to the victims' remains.

Prosecutors allege that the murders were premeditated, though a specific motive has yet to be disclosed.

The USF community has held vigils for Limon and Bristy, who were highly regarded researchers in the engineering department, as the university provides counseling services to students and faculty affected by the loss.
