Missing Students and Investigation Overview
Zamil Limon and Nahida Bristy, both 27-year-old doctoral students at the University of South Florida (USF), have been missing since April 16, 2023. Limon, who is studying geography, environmental science, and policy, was last seen at his residence around 9 a.m., while Bristy, a chemical engineering student, was last seen at the Natural and Environmental Sciences Building on campus at 10 a.m. A family friend reported their disappearance to the USF Police Department (USFPD) on April 17 after being unable to contact them. Both students have since been entered into state and national missing persons databases.
Background and Context
Limon and Bristy, originally from Bangladesh, were described by friends and family as responsible and dedicated students. They had previously discussed a potential future together, including marriage, but were focused on completing their degrees. Limon's brother, Zubaer Ahmed, noted that his brother was busy working on his thesis, which involves using generative AI to study Florida's shrinking wetlands, just days before his disappearance.
Family Concerns and Official Responses
Family members have expressed deep concern over the unusual nature of the students' disappearance, emphasizing that it is out of character for them to go off the grid without communication. Ahmed stated, “In my wildest dream, I don’t think he will do that,” highlighting the family's belief that both students would not willingly vanish. The USFPD has confirmed that there is no indication of foul play or that the students are in the custody of Immigration and Customs Enforcement (ICE).
Criticism and Opposition
Despite the ongoing investigation, family members have criticized the police for the timing of their public appeal for information, suggesting that it may have come too late. Zubaer Ahmed mentioned that police initially advised the family against going public, as they suspected the case could involve abduction. The family is now urging anyone with information to come forward.
Current Status of the Investigation
The USFPD, along with the Hillsborough County Sheriff's Office, is actively investigating the case. They have requested DNA samples from the families and are exploring all leads. Public Information Officer Larry McKinnon stated, “When we get to this point where we aren’t having success in locating them, then our next best source is the public.” Authorities are appealing for anyone who may have seen Limon or Bristy to contact them at (813) 974-2628.
