Incident Overview
On April 16 2026, two University of South Florida (USF) doctoral students—Zamil Limon, 27, a geography and environmental-science Ph.D. candidate, and Nahida Bristy, 27, a chemical-engineering Ph.D. candidate—were last seen in Tampa. Their off-campus roommate, 26-year-old Hisham Abugharbieh, was later arrested and charged with two counts of first-degree premeditated murder, along with offenses for moving a dead body, failing to report a death, tampering with evidence, false imprisonment and battery. Limon’s decomposing body was recovered on the Howard Franklin Bridge in heavy-duty trash bags; Bristy remains missing, though investigators consider her unlikely to be alive.

- April 28 – Pre-trial detention hearing scheduled.
Evidence and Digital Footprint
Court filings detail a CVS receipt (April 16) listing trash bags, Lysol wipes and Febreze. Blood spatter was documented throughout the shared apartment, including two human-sized patterns in Abugharbieh’s bedroom. Items recovered from the dumpster—Limon’s student ID, credit cards, a gray shirt (DNA matched Limon) and a kitchen mat (DNA matched Bristy)—link the victims to the disposal site. Phone-location records corroborate Abugharbieh’s presence near the bridge at the time Limon’s body was placed there. The ChatGPT exchanges are cited as evidence of premeditation.
Official Statements & Responses
The Hillsborough County Sheriff’s Office, represented by Chief Deputy Joseph Maurer, emphasized that detectives “link the suspect to this case and to Limon’s body” and indicated no indication of an accomplice. Sheriff Chad Chronister called the case “deeply disturbing” and pledged relentless investigative effort. USF President Moez Limayem assured the campus community that there is “no ongoing threat to the safety of the university community.” The Hillsborough County Public Defender’s Office confirmed representation of Abugharbieh and declined further comment. Family members of both victims have requested that the bodies be handled according to Islamic funeral rites.
Criticism & Opposition
Bristy’s brother, Zahid Hasan Pranto, told media that investigators told the family she is “no longer with us” and that the volume of blood suggests possible dismemberment, prompting calls for accountability regarding the off-campus housing complex where the victims lived. Community members have expressed concern that background checks on roommates were insufficient.
