Hisham Abugharbieh, 26, a former student of the University of South Florida (USF), has been charged with two counts of premeditated first-degree murder with a weapon. The charges stem from the death of Zamil Limon and the disappearance of Nahida Bristy, both doctoral students from Bangladesh.

Investigation and Arrest

The investigation began on April 16th following reports of Limon and Bristy’s disappearance. It quickly escalated into a standoff with authorities at Abugharbieh’s family home near the USF campus.

Standoff with Law Enforcement

Law enforcement initially responded to a report of domestic violence at the residence. After securing the safety of his family, Abugharbieh barricaded himself inside. A SWAT team, utilizing a drone, a robot, and crisis negotiators, was deployed to attempt a peaceful resolution.

After several hours, Abugharbieh surrendered, emerging from the house with his hands raised and wearing only a blue towel.

The Victims and Ongoing Search

The remains of Zamil Limon, 27, were discovered on the Howard Frankland bridge on Friday morning. Nahida Bristy, also 27, remains missing, and an active search is underway.

Students' Backgrounds

Limon was pursuing studies in geography, environmental science, and policy. Bristy was a Ph.D. candidate in chemical engineering, having previously graduated from Noakhali Science and Technology University. The couple was reportedly considering marriage and were well-regarded within the university community.

University and Family Response

The University of South Florida has expressed profound sadness over the loss of Bristy, describing her as a ‘talented and promising student.’ Vice Chancellor Mohammad Ismail called for justice and compensation for her family.

Past Legal Issues

Abugharbieh has a history of legal issues, including arrests for battery and burglary in 2023. He successfully completed a diversion program in 2024, leading to the dismissal of those charges. Court records also show two domestic violence petitions filed by a family member in 2023, one resulting in a protective injunction.

Authorities are urging anyone with information regarding Bristy’s disappearance to contact the Hillsborough County Sheriff’s Office. The investigation is ongoing, and autopsy results for Limon are expected Saturday morning.
