Roommate charged with murder in deaths of two USF doctoral students

A former University of South Florida student has been charged with two counts of murder in the deaths of two fellow doctoral candidates, both from Bangladesh, who vanished earlier this month. Hisham Abugharbieh, the man accused, was taken into custody after a tense standoff at a Tampa residence, where he had barricaded himself and was seen on camera wearing only a towel.

The victims, Zamil Limon and Nahida Bristy, were reported missing on April 16. Both were pursuing advanced degrees in public health at USF and were known to be close collaborators on research projects. Limon's body was later discovered in a landfill outside the city, according to law enforcement. Bristy has not been found, but officials say they believe she is also deceased and that Abugharbieh is responsible for both deaths.

The investigation took a dramatic turn when police traced digital activity and surveillance footage to a home in Tampa linked to Abugharbieh. After hours-long negotiations, he surrendered peacefully to SWAT officers. No injuries were reported during the standoff. Authorities say evidence collected at the scene, including digital records and personal belongings belonging to the victims, helped build the case against him.

While the motive remains under investigation, early reports suggest tensions may have stemmed from personal disagreements over shared living arrangements and academic pressures. Abugharbieh and Limon had been roommates, and sources close to the case say there had been recent disputes between them. Investigators are also reviewing communications and online activity in the days leading up to the disappearances.

The case has sent shockwaves through the USF campus and the broader international student community. Many students from South Asia have expressed concern about safety and the level of institutional support available during personal crises. University officials have since announced plans to expand mental health outreach and emergency response protocols for graduate researchers.

USF released a statement expressing deep sorrow over the loss of two promising scholars. 'Zamil and Nahida were valued members of our academic community,' the statement read. 'Their dedication to public health research made a difference, and their absence leaves a void we cannot fill.'

Abugharbieh is being held without bond and is expected to appear in court next week. Prosecutors say they are preparing to present additional forensic and digital evidence as the case moves forward. Meanwhile, search efforts for Bristy continue, though authorities have not indicated where they believe her remains might be located.
