Devastating Confirmation: Nahida Bristy’s Remains Identified Through DNA in USF Doctoral Students Murder Investigation.

Hillsborough County authorities delivered the final tragic confirmation on May 1, 2026: human remains recovered from Tampa Bay have been positively identified as 27-year-old Nahida Bristy, the second missing University of South Florida doctoral student. The identification, achieved through DNA matching, dental records, and clothing evidence, ends weeks of anguished searching and solidifies the murder case against suspect Hisham Saleh Abugharbieh.

Bristy, a chemical engineering PhD candidate from Bangladesh, disappeared alongside fellow student Zamil Limon on April 16, 2026. Limon’s remains were discovered days earlier in a trash bag on the Howard Frankland Bridge. Bristy’s remains were located by a kayaker in the mangroves near the Pinellas County side of the bridge. Both victims had been stabbed, with their bodies disposed of in plastic bags in similar locations.

Abugharbieh, Limon’s 26-year-old roommate and a former USF student, was arrested following a barricaded standoff at his family home during a domestic violence call. He now faces two counts of first-degree premeditated murder with a weapon. Additional charges include unlawfully moving a dead body, failure to report a death, evidence tampering, false imprisonment, and battery. Investigators cite phone data showing searches related to knives, body disposal, and AI queries about concealing corpses.

The two students were close friends who had reportedly discussed marriage. Bristy’s brother remembered her as the “perfect sister” full of dreams. Limon’s family noted he had expressed unease about his roommate before the tragedy. Both sets of remains are being prepared for repatriation to Bangladesh to honor religious customs. USF held a vigil honoring the “exemplary students” and provided support services.

Sheriff Chad Chronister described the crimes as “pure evil” while praising the collaborative efforts of dive teams and detectives. The case has shaken the international student community at USF and raised urgent questions about roommate safety, mental health awareness, and campus security protocols.

Abugharbieh had a prior record involving battery and domestic violence petitions. He remains in custody without bond as prosecutors prepare for grand jury proceedings and are expected to seek the death penalty. No other suspects are involved.

This heartbreaking resolution brings painful closure to the search but leaves families grieving two young lives full of promise. The double homicide serves as a sobering reminder of the potential dangers in shared living situations and the importance of heeding early warning signs.
