Zamil Limon and Nahida Bristy, Both 27, University of South Florida Doctoral Students, Missing for a Week: Authorities Carry Out Investigation
The community of University of South Florida in Tampa is facing growing concern and uncertainty after two 27-year-old doctoral students, Zamil Limon and Nahida Bristy, were reported missing and have not been seen for nearly a week. Their sudden disappearance on April 16 has deeply unsettled classmates, faculty members, families, and investigators, all of whom are now urgently trying to understand what happened in the hours after they were last seen.
Zamil Limon, a doctoral candidate in geography, environmental science, and policy, was last confirmed at his residence on Avalon Heights Boulevard around 9 a.m. on April 16. He is described as a focused and dedicated researcher whose academic work explores the relationship between environmental systems and public policy. After that morning, there has been no confirmed communication from him.
Just an hour later, Nahida Bristy, also 27 and a doctoral student in chemical engineering, was last seen on the USF Tampa campus at the Natural & Environmental Sciences Building. Known for her intelligence, discipline, and commitment to research, she was reportedly engaged in academic work at the time. After that point, she too vanished without explanation.
The timing of their disappearances has raised serious concern. The two students were known to each other as friends, and investigators are carefully examining whether their cases are connected. A mutual acquaintance, unable to reach either of them, eventually reported both missing on April 17 after repeated unsuccessful attempts to contact them.
Since then, the investigation has expanded rapidly. The University of South Florida Police Department and the Hillsborough County Sheriff’s Office are working together, reviewing surveillance footage, tracking digital activity, and interviewing people who may have seen or spoken with either student before they disappeared. Both individuals have been entered into state and national missing persons databases.
Authorities have not confirmed whether foul play is suspected, but the coordinated disappearance of two close associates within a short time frame has heightened concern. Investigators are considering all possibilities, including voluntary disappearance, accidental circumstances, or something more serious. At this stage, no scenario has been ruled out.
The University of South Florida community has responded with anxiety and solidarity. Students and faculty have shared missing-person notices, while counseling services have been made available to those affected. The situation has cast a shadow over campus life, with many expressing fear, sadness, and hope for answers.
Families of both Zamil Limon and Nahida Bristy are enduring an agonizing wait, holding onto hope while pleading for any information that could lead to their loved ones. Nearly a week without contact has only deepened their distress.
As investigators continue their work, authorities are urging the public to remain vigilant and report any possible sightings or information. For now, the disappearance of two promising young scholars remains an unresolved and deeply troubling mystery—one that has left a community searching for answers and hoping for their safe return.
