In a heartbreaking development that has closed one painful chapter while reopening wounds for loved ones, authorities in Hillsborough County, Florida, have positively identified the second set of human remains discovered in Tampa Bay as those of Nahida Bristy, a 27-year-old doctoral student in chemical engineering at the University of South Florida. The announcement on May 1, 2026, by Hillsborough County Sheriff Chad Chronister marks the grim conclusion of the search for Bristy and her fellow student Zamil Limon, both from Bangladesh, who were last seen on April 16, 2026. Their deaths are alleged to be the work of a calculated killer living in close proximity — Limon’s own roommate.

Zamil Limon, studying geography, environmental science, and policy, and Nahida Bristy had built promising academic careers far from home. Their disappearance triggered an urgent missing persons investigation that quickly turned into a double homicide case. Limon’s body, showing multiple stab wounds, was discovered first on April 24, 2026, inside black plastic garbage bags near the Howard Frankland Bridge over Tampa Bay. Two days later, on April 26, a kayaker’s fishing line snagged another garbage bag floating in the water just south of that location. Inside was a heavily decomposed body.

Identification of Bristy’s remains took several days due to advanced decomposition. Sheriff Chronister confirmed the match through DNA analysis, dental records, and clothing that matched what Bristy was last seen wearing on university surveillance footage. Both victims had suffered multiple sharp force injuries. The bodies had been disposed of in a similar manner — tied in garbage bags — suggesting a deliberate attempt to conceal the crimes.

Limon’s roommate, 26-year-old Hisham Saleh Abugharbieh (also referred to as Hisham Abugharbieh), a former USF student, faces two counts of first-degree premeditated murder with a weapon. He is also charged with unlawfully moving dead bodies, failure to report deaths with intent to conceal, tampering with evidence, false imprisonment, and battery. Abugharbieh was arrested on April 24 following a brief standoff. He remains held without bond as the case proceeds toward a grand jury, where prosecutors are considering the death penalty.

The crime scene at the Avalon Heights apartment complex painted a picture of horror. Forensic evidence revealed extensive blood trails from the kitchen into the bedroom, with the outline of a body in a fetal position visible near the suspect’s bed. The air conditioning had been turned to its coldest setting to slow decomposition and mask odors. A missing doormat, believed to have absorbed initial blood evidence, was later linked to items discarded in the complex dumpster, where Limon’s blood-soaked belongings were recovered.

Digital evidence has further shocked investigators. Court records indicate Abugharbieh allegedly searched topics including body disposal methods and even queried ChatGPT with questions about hiding corpses days before the disappearances. He is accused of using the victims’ phones to send impersonating messages, maintaining the facade that they were alive and well.

Warning signs had surfaced earlier. Other roommates had complained about Abugharbieh’s disturbing behavior. Nahida reportedly felt uneasy during prior visits to the apartment, sensing something unsettling. Limon and another resident had filed a complaint against him weeks before the murders after learning of his prior record.

The victims’ families in Bangladesh received the devastating news directly from authorities. Bristy’s brother described her as the “perfect sister” and “perfect daughter,” a talented young woman who dreamed of returning home after her studies to contribute to society. Limon’s remains were expected to be repatriated soon in accordance with Islamic traditions, with Bristy’s following. USF held vigils honoring both as exemplary students and “family away from home.”

Sheriff Chronister called the crimes “pure evil” that go against American values of safety and opportunity for those pursuing better lives. The case has sparked urgent discussions on off-campus housing safety, mental health resources for students, thorough background checks for shared living, and support for international students navigating life far from their support systems.

As the legal process advances, the focus remains on justice for Zamil Limon and Nahida Bristy — two bright, ambitious individuals whose futures were violently stolen. Their story serves as a tragic reminder of how danger can hide in everyday settings and the lasting impact on families left behind across the globe.
