Two USF Doctoral Students From Bangladesh Missing Since April 16 In Tampa Area

Two University of South Florida doctoral students from Bangladesh have been missing in the Tampa area since April 16. Authorities identified them as 27-year-olds Zamil Limon and Nahida Bristy. Limon, an environmental science doctoral candidate studying artificial intelligence applications, was last seen about 9 a.m. April 16 at his Tampa residence. Bristy, a chemical engineering doctoral student, was last seen about 10 a.m. April 16 on the USF Tampa campus.

Hillsborough County detectives say they are actively following leads and conducting searches in multiple locations across Hillsborough and Pinellas counties. Family members and friends describe the disappearances as "extremely suspicious" and out of character, noting the pair had daily contact and already booked summer flights to Bangladesh. A lab colleague said Limon had marked "work from home" on a shared Outlook calendar the day they vanished. Relatives also say the two had discussed a future together but prioritized their studies, adding to the family's alarm.

Early reports simply noted that two students were missing without many specifics. More recent coverage, including a post by CBS News on Facebook, provided names, exact last-seen times and locations, and law enforcement updates that clarified the timeline. Fox News ran an early story but did not add the detailed timelines and family accounts that later reporting supplied.
