Roommate Charged in Deaths of Two Missing University of South Florida Doctoral Students
Hillsborough County authorities have charged Hisham Abugharbieh with two counts of first-degree murder in the deaths of University of South Florida doctoral students Zamil Limon and Nahida Bristy. The charges follow the discovery of Limon’s remains on the Howard Frankland Bridge and an ongoing search for Bristy, who remains missing.
Discovery and Arrest
Zamil Limon’s body was found on Friday on the Howard Frankland Bridge, prompting a homicide investigation. Shortly after, law enforcement responded to a domestic violence incident at Abugharbieh’s residence, leading to his arrest. Hillsborough County Sheriff’s Office announced that Abugharbieh was charged with two counts of murder in the first degree with a weapon, premeditated, in connection with both Limon’s and Bristy’s deaths.
“Evidence was presented to the State Attorney’s Office, resulting in further charges against Abugharbieh,” the sheriff’s office stated. “At this time, the search for Bristy continues.”
Ongoing Investigation
Investigators have been searching waters near the Howard Frankland Bridge for Nahida Bristy, using marine and dive teams. Bristy’s family in Bangladesh has been notified, and officials said they believe she may be deceased based on the amount of blood found in the apartment shared by Limon and Abugharbieh.

Sheriff Chad Chronister described the case as “deeply disturbing,” noting its impact on the community and those hoping for a safe resolution.
Victim Background
Zamil Limon and Nahida Bristy were both doctoral students at the University of South Florida and had been reported missing the previous week. They were known to be close friends and roommates of Abugharbieh before their disappearance.
The case remains active as authorities continue to search for Bristy and gather evidence for prosecution.
