In the quiet corridors of the University of South Florida, two promising doctoral students from Bangladesh—Zamil Limon and Nahida Bristy—were forging bright futures in academia. Limon pursued a PhD in geography, environmental science, and policy, while Bristy specialized in chemical engineering. Both 27 years old, the pair shared a close bond that friends described as loving and supportive, with some noting they had discussed marriage. Their dreams were shattered in mid-April 2026 in one of Tampa’s most shocking crimes.

New revelations paint a disturbing picture of the days and hours leading up to the tragedy on April 16. Limon had repeatedly expressed unease about his roommate, 26-year-old Hisham Abugharbieh, describing him as unsocial, unpleasant, and exhibiting troubling behavior. According to Limon’s brother, Zubaer Ahmed, Limon and another roommate had filed a formal complaint with their off-campus housing facility at Avalon Heights weeks earlier, highlighting concerns that allegedly went unaddressed. This tension simmered in the shared apartment where the three lived, creating an atmosphere of discomfort that Limon confided to family back home.

On the morning of April 16, Limon was last seen around 9 a.m. at the apartment. Bristy was captured on campus surveillance video around noon. The pair stayed in phone contact throughout the day, their conversations seemingly routine. However, as evening fell, phone data and traffic records suggest movements that aligned with the suspect’s locations. Investigators believe the attacks occurred later that night in or near the apartment. Both victims suffered multiple stab wounds. Their bodies were bound, placed in garbage bags, and disposed of in chillingly methodical ways—Limon’s remains discovered under the Howard Frankland Bridge, Bristy’s later found in Tampa Bay mangroves.

Abugharbieh, Limon’s roommate and a former USF student, faces two counts of premeditated first-degree murder with a weapon, along with charges related to body disposal and evidence tampering. Authorities recovered incriminating evidence inside the residence, including blood traces, and noted the suspect’s movements matching the timeline of the crimes. Some reports mention his online searches showing violent interests in the period before the incident, though the exact motive remains under investigation. Family members have speculated on possible resentment or obsession tied to the victims’ success and relationship, but emphasize that no justification can explain such brutality.

The case has sent shockwaves through the Bangladeshi diaspora and USF community. Vigils have drawn hundreds mourning the loss of two dedicated scholars. USF has announced posthumous doctoral degrees for both, a small gesture of recognition for lives cut short. Their bodies have been repatriated to Bangladesh for burial, leaving families devastated and demanding justice.

This tragedy raises urgent questions about roommate screening, mental health support in student housing, and how early warning signs of interpersonal conflict can escalate unnoticed. As the legal process unfolds, the focus remains on honoring Limon and Bristy’s legacies—bright young minds who came to America chasing knowledge, only to encounter unimaginable horror in what should have been a safe space.
