Disappearance, Discovery, and Arrest
On April 16 2026, two 27-year-old Bangladeshi doctoral candidates—Zamil Limon, a geography, environmental science and policy student, and Nahida Bristy, a chemical-engineering scholar—were last seen in Tampa, Florida. Limon vanished from his off-campus apartment on Avalon Heights Boulevard; an hour later Bristy disappeared from the Natural and Environmental Sciences building on the University of South Florida (USF) campus. A family friend reported the pair missing on April 17. After the case was upgraded to “endangered” on April 23, investigators found Limon’s remains on the Howard Frankland Bridge on April 24. The same day, Hisham Saleh Abugharbeih, Limon’s 26-year-old roommate, was arrested after a domestic-violence call led to a SWAT standoff at his family home in the Lake Forest community. He surrendered peacefully, wearing only a blue towel.

Official Statements & Responses
Chief Deputy Joseph Maurer said the autopsy would determine Limon’s cause of death and confirmed the search for Bristy remained active. Sheriff Chad Chronister emphasized that investigators “are working tirelessly and relentlessly to uncover the truth.” USF President Moez Limayem assured the campus community that there is “no ongoing threat to the safety of the university” and pledged continued support for the families.
Criticism & Opposition
Bristy’s brother Zahid Pranto expressed disbelief that his sister, who “had been in daily contact with her family,” could simply disappear, stating, “There has been no single day without contact with her.” Limon’s brother Zubaer Ahmed lamented the loss of a “joyful, promising researcher” who was scheduled to defend his thesis that week.
On-the-Ground Reports
Deputies removed Abugharbeih’s family from the residence before he barricaded himself. A SWAT team, bomb-disposal unit, crisis-negotiation team, drone, and robot were deployed. After roughly 20 minutes, Abugharbeih emerged with his hands raised, still wrapped only in a towel, and was taken into custody without injury.
