Authorities in Tampa have elevated the status of two missing doctoral students from the University of South Florida (USF) to “endangered.” This update came after the Hillsborough County Sheriff’s Office received new information regarding their disappearance. On Friday, April 24, officials confirmed that both individuals, Zamil Limon and Nahida Bristy, aged 27 and originally from Bangladesh, were last seen separately on April 16 and reported missing by a mutual acquaintance the following day.

The situation surrounding Limon and Bristy has garnered increasing public attention and concern. Initially labelled as missing persons, the sheriff’s office revised their classification to endangered, highlighting the gravity of the circumstances. A short while after this announcement, law enforcement officials reported the apprehension of a barricaded person connected to the case in Tampa. Although specific details about the arrested individual have not been disclosed, the sheriff’s office stated that the situation had been resolved and further information would be provided in a forthcoming press conference.

Zamil Limon was last spotted at his residence on Avalon Heights Boulevard at approximately 9 a.m. on April 16. He was pursuing advanced studies in geography, environmental science, and policy, with an emphasis on the integration of artificial intelligence in environmental research. Just days before his disappearance, Limon had reportedly requested that family members refrain from contacting him unless it was an emergency, as he was preparing to present his thesis.
Nahida Bristy, on the other hand, was last seen at the NES Building on the USF Tampa campus around 10 a.m. on the same day. Pursuing a degree in chemical engineering, Bristy had been focused on her academic work as well. According to her older brother, Zahaid Hasan Pranto, the two students had a romantic history but were currently concentrating on their studies rather than their relationship.
The families of both students have expressed deep concern about their sudden disappearance. Limon’s brother, Zubaer Ahmed, noted that the couple was contemplating a future together but remained dedicated to their respective academic pursuits. He described them as serious individuals who would not inexplicably vanish without informing anyone.
Details regarding their last known whereabouts add to the mystery surrounding their cases. Limon left his apartment with his phone and wallet, but his passport was left behind. Contrarily, Bristy left her laptop, tablet, and lunch box at a laboratory on campus. These apparent anomalies have raised concerns among their families and friends, who insist that Limon and Bristy would not willingly choose to disappear.
The USF Police Department has actively sought public assistance in locating the missing students. Public Information Officer Larry McKinnon stated that finding Limon and Bristy remains the top priority for law enforcement. The department urges anyone with relevant information to step forward and assist in their efforts.
As the search for the two students continues, friends, family, and the broader community remain hopeful for their safe return. Authorities encourage anyone who may have seen them or has other crucial information to contact the Hillsborough County Sheriff’s Office at 813-247-8200 or the USF Police Department at 813-974-2628.
The increasing urgency surrounding this case has highlighted the importance of community vigilance, with local residents and students rallying together to aid in the search for their missing peers. As developments unfold, updates will be closely monitored, and the hope remains that Zamil Limon and Nahida Bristy will be found safe and sound.
