The University of South Florida campus remains in mourning following the brutal murders of two promising 27-year-old doctoral students from Bangladesh. Zamil Limon and Nahida Bristy vanished on April 16, 2026. Their bodies have since been recovered in horrific circumstances, and authorities have charged Limon’s roommate, Hisham Saleh Abugharbieh, 26, with two counts of first-degree premeditated murder with a weapon.

Limon, pursuing studies in geography and environmental science and policy, and Bristy, a chemical engineering doctoral student, were described by loved ones as dedicated scholars with bright futures. They were close friends reportedly considering marriage. Bristy lived on campus, while Limon shared an off-campus apartment with Abugharbieh. A family friend alerted police after both went silent.

The breakthrough came on April 24 during a domestic violence response at Abugharbieh’s family home. Officers evacuated relatives before he barricaded himself inside. A full tactical response — including SWAT, a drone, robot, and negotiators — ended with Abugharbieh surrendering peacefully, wearing only a blue towel. That same day, Limon’s remains were found in a trash bag on the Howard Frankland Bridge. On May 1, Bristy’s remains were identified after a kayaker discovered them in nearby mangroves. Both had been stabbed to death.

Prosecutors outlined a disturbing timeline in court filings. Phone records allegedly show Abugharbieh researching knives, body disposal techniques, and using ChatGPT to ask about hiding corpses. Evidence recovered from the apartment further supports premeditation. Abugharbieh initially cooperated with detectives before stopping, only to resume speaking after his arrest. He now faces multiple additional charges: unlawfully moving a dead body, failure to report a death with intent to conceal, tampering with evidence, false imprisonment, and battery.

Abugharbieh, a former USF student no longer enrolled, had prior arrests for battery and domestic violence-related issues. He completed a diversion program for earlier misdemeanors. A judge ordered him held without bond. The State Attorney’s Office plans to present the case to a grand jury and is expected to seek the death penalty.

The victims’ families are devastated. Bristy’s brother called her the “perfect sister” who dreamed of returning home. Limon’s relatives revealed he had complained about his roommate’s “psychopathic behavior” beforehand. Both sets of remains are being repatriated to Bangladesh for burial. USF held a vigil to honor the pair as “exemplary students” and provided counseling support.

Hillsborough County Sheriff Chad Chronister described the killings as “pure evil” and highlighted the relentless efforts of dive teams and investigators. No other suspects are being sought. The case has sparked widespread concern about safety for international students, roommate screening, and early intervention for concerning behavior on and off campus.

Friends remember Limon and Bristy as kind, ambitious individuals who contributed greatly to their academic fields. Their sudden, violent deaths have left the USF community and the broader Bangladeshi diaspora reeling. As more evidence emerges, the motive appears tied to personal conflicts, though full details remain under investigation.

This tragedy underscores the hidden risks in shared living situations and the critical need for mental health resources and reporting mechanisms. While justice moves forward for Zamil Limon and Nahida Bristy, their bright potential cut short serves as a painful reminder that safety must remain a priority in academic communities.
