Roommate Charged with Double Murder in Tragic Deaths of USF Doctoral Students Zamil Limon and Nahida Bristy
Tampa, Florida – A devastating turn in the case of two missing University of South Florida doctoral students has led to murder charges against their roommate, as authorities confirm the recovery of one victim’s remains and intensify the search for the second.[1][2]
Discovery of Remains and Initial Arrest
Zamil Limon, 27, a promising doctoral candidate in environmental science focusing on AI applications, was found dead on Friday morning under the Howard Franklin Bridge in Tampa. Chief Deputy Joseph Maurer of the Hillsborough County Sheriff’s Office announced the grim discovery during a press conference, noting that Limon and fellow student Nahida Bristy, also 27, had been missing since April 16.[1][2][4]
Hours after the remains were located, deputies responded to a domestic violence call at a residence in the Lake Forest Community near USF’s Tampa campus. There, they arrested Hisham Abugharbieh, 26, Limon’s roommate, following a SWAT standoff where he had barricaded himself inside.[4][5]
Abugharbieh was initially charged with domestic violence, evidence tampering, failure to report a death, and unlawfully handling a dead body.[1][4] Investigators revealed he had been interviewed earlier in the disappearance probe.[4]
Escalation to First-Degree Murder Charges
By Saturday, the case took a darker turn. The Hillsborough County Sheriff’s Office presented evidence to the state attorney’s office, resulting in two counts of first-degree murder against Abugharbieh for the deaths of both Limon and Bristy. The charges specify premeditated murder with a weapon.[2]
Bristy remains missing, but her family told CBS News that police indicated she is likely deceased, citing the significant volume of blood found at the shared residence.[2] Dive teams continued searching near the Howard Franklin Bridge on Friday afternoon, with efforts ongoing into Saturday.[1][2]
Victims’ Backgrounds and Community Impact
Limon was on the cusp of a major milestone, scheduled to present his doctoral thesis this week on using artificial intelligence in environmental science, according to his family.[1][2] Bristy, described in reports as Limon’s friend, was also pursuing advanced studies at USF.[3]
The University of South Florida community is reeling from the loss. Both students were last seen in separate locations in the Tampa area on April 16, prompting an endangered missing persons alert.[4] USF Police had been involved from the outset.[4]
“We are still actively searching for Nahida,” Chief Deputy Maurer stated during Friday’s news conference, emphasizing the urgency of the operation.[4]
Investigation Details and Next Steps
The investigation accelerated after the domestic violence 911 call around 9 a.m. Friday. Abugharbieh’s arrest came swiftly, with authorities noting his connection to Limon as roommates.[1][5] An autopsy on Limon is pending to determine the exact cause of death.[1][2]
Former Sheriff’s Detective Jamie Copenhaver, speaking on FOX 35, highlighted the focus on recovering Bristy, expressing cautious optimism during interviews but acknowledging the grim outlook.[5] “Their main goal right this moment is to find out where this missing female student is,” Copenhaver said.[5]

Broader Implications for Campus Safety
This tragedy has sparked concerns about student safety in off-campus housing near universities. The Lake Forest Community, popular among USF students, now finds itself at the center of a high-profile homicide investigation.[1]
Authorities urge anyone with information on Bristy’s whereabouts to come forward. The Sheriff’s Office has not released additional details on the motive or sequence of events, pending further investigation.[2]
Limon’s family expressed profound grief, remembering him as a dedicated scholar whose work could have advanced environmental solutions through AI.[1][2] As the search continues, Tampa braces for more developments in this heartbreaking case.
