The Disappearance and Discovery
On the morning of April 16, 2026, two 27-year-old University of South Florida (USF) doctoral students from Bangladesh—Zamil Limon, a geography, environmental-science and policy candidate, and Nahida Bristy, a chemical-engineering candidate—were last seen at separate locations in Tampa. Limon vanished from his off-campus apartment on Avalon Heights Boulevard around 9 a.m.; Bristy disappeared from the Natural & Environmental Sciences (NES) building on campus about an hour later. After a family friend reported them missing on April 17, investigators elevated the case to “endangered” on April 23.
A domestic-violence call to the home of Limon’s roommate, Hisham Saleh Abugharbeih, prompted a SWAT response on April 24. The suspect barricaded himself for roughly 20 minutes before surrendering peacefully. Later that morning, deputies recovered human remains on the Howard Franklin Bridge; forensic analysis identified the remains as Limon. Bristy remains unlocated.
Background & Context
Both students were in the United States on F-1 visas and were described by family members as a close couple planning marriage. Limon was preparing a thesis on using generative AI to model Florida’s shrinking wetlands. The university’s police and the Hillsborough County Sheriff’s Office (HCSO) coordinated the missing-persons investigation, later classifying it as “endangered” after new information surfaced.
