A trusted roommate allegedly betrayed two promising University of South Florida doctoral students, charging them with first-degree murder in a shocking off-campus double homicide that exposes vulnerabilities in everyday American life.
Story Snapshot
- Hisham Abugharbieh, 26, faces two counts of first-degree premeditated murder for the deaths of roommates Zamil Limon and Nahida Bristy, both 27-year-old USF doctoral candidates.
- Limon’s body was discovered on the Howard Frankland Bridge in Tampa; Bristy remains missing, presumed killed and possibly dismembered based on blood evidence at their shared home.
- Case escalated from a missing persons report on April 17 to arrest on April 25 after a domestic violence call revealed critical evidence.
- Abugharbieh held without bond, with pre-trial set for April 28; search for Bristy’s remains continues near the bridge.
Tragic Timeline Unfolds
On April 16, Zamil Limon was last seen around 9 a.m. at the shared residence on Avalon Heights Blvd in Tampa’s Lake Forest Community near USF Tampa campus. Nahida Bristy was spotted around 10 a.m. at the NES Building on campus. Both high-achieving international students vanished without trace, Limon pursuing a doctorate in geography, environmental science, and policy using AI with a thesis presentation imminent, Bristy in chemical engineering.
From Welfare Check to Arrest
A family friend contacted USF Police Department around 5 p.m. on April 17 after failing to reach the victims. The case intensified on Friday, April 25, when Hillsborough County Sheriff’s Office deputies responded to a domestic violence call at the home. Abugharbieh barricaded himself before surrendering. Investigators found blood evidence linking him to the crimes, leading to Limon’s remains discovery on the Howard Frankland Bridge that day.
Abugharbieh faced initial charges of battery, false imprisonment, tampering with evidence, failure to report a death, and unlawful body movement. The State Attorney’s Office reviewed evidence overnight, upgrading charges to two counts of first-degree premeditated murder with a weapon by Saturday.
Investigation and Family Heartbreak
HCSO Chief Deputy Joseph Maurer confirmed the bridge discovery. Police informed Bristy’s brother, Zahid Prato, that she is “no longer with us,” with her body possibly dismembered and difficult to recover. Families of both victims grieve amid uncertainty, Limon’s autopsy pending cause of death details. HCSO withholds motive and method to protect the ongoing probe.

Broader Implications for Communities
USF students and faculty face heightened safety concerns in off-campus housing, prompting potential policy reviews. Tampa and Hillsborough residents encounter bridge search disruptions. International student recruitment at USF may suffer long-term from awareness of risks in shared living near campuses. This isolated household betrayal underscores failures in personal trust and rapid law enforcement response, fueling frustrations over societal vulnerabilities that limited government struggles to address.
Both conservatives and liberals share dismay at such breakdowns, where elite institutions like universities prioritize agendas over basic protections for hardworking individuals chasing the American Dream through education and determination. Pre-trial hearing occurs April 28 at 9 a.m.; tips on Bristy sought at (813) 247-8200.
