Human Remains Found in Tampa Bay as Search Continues for Missing USF Doctoral Student Nahida Bristy
The search for two missing University of South Florida (USF) doctoral students took a devastating turn last week when authorities confirmed the discovery of human remains belonging to one of the students, 27-year-old Zamil Limon. His body was found on the Howard Frankland Bridge in Tampa, Florida, on the morning of April 24, 2026, according to the Hillsborough County Sheriff’s Office. The grim development has intensified efforts to locate his girlfriend, Nahida Bristy, another USF doctoral student who remains missing and is now presumed dead by investigators.
The case has sent shockwaves through the Tampa Bay community and beyond, raising urgent questions about the safety of international students and the circumstances surrounding the students’ disappearances. Authorities have arrested and charged Limon’s roommate, 26-year-old Hisham Abugharbieh, with two counts of first-degree murder in connection with the deaths of both Limon and Bristy. The case has as well drawn attention to the vulnerabilities faced by students far from home, particularly those navigating complex personal and academic pressures.
As the investigation unfolds, families, friends and the broader USF community are grappling with grief and demanding answers. The Hillsborough County Sheriff’s Office has vowed to leave no stone unturned in their search for Bristy, even as evidence suggests her remains may also be in the waters near the Howard Frankland Bridge.
A Timeline of Disappearance and Discovery
The disappearances of Zamil Limon and Nahida Bristy were first reported on April 17, 2026, nearly a week after they were last seen alive. According to a detailed timeline published by 10 Tampa Bay, Limon, a doctoral student in geography, environmental science, and policy, was last seen at his home on Avalon Heights Boulevard in Tampa at approximately 9 a.m. On April 16. Bristy, who was pursuing a doctoral degree in chemical engineering, was last seen at the NES Building on the USF campus around 10 a.m. The same day.
By the time their disappearances were reported to authorities, concerns were already mounting. The Hillsborough County Sheriff’s Office quickly classified both students as “endangered” and launched a multi-agency search effort. The breakthrough in the case came on April 24, when Limon’s remains were discovered on the Howard Frankland Bridge, a critical span connecting Tampa and St. Petersburg. The bridge has since become a focal point of the investigation, with dive teams scouring the waters below for any sign of Bristy.
In a press conference held later that day, Joseph Maurer of the Hillsborough County Sheriff’s Office confirmed that authorities were treating the case as a homicide. “We are still actively searching for Nahida,” Maurer told reporters, emphasizing the urgency of the ongoing efforts. The sheriff’s office also revealed that a 911 call had been placed earlier that morning reporting a domestic violence disturbance at a residence where Abugharbieh, Limon’s roommate, had barricaded himself. After a brief standoff, Abugharbieh surrendered to authorities and was taken into custody.

Charges Filed Against Roommate Hisham Abugharbieh
On April 25, 2026, the Hillsborough County Sheriff’s Office announced that Abugharbieh had been charged with two counts of first-degree murder with a weapon in the deaths of both Limon and Bristy. The charges came after investigators uncovered evidence linking Abugharbieh to the crimes, though the exact nature of that evidence has not been publicly disclosed. According to court documents, Abugharbieh was initially taken into custody on multiple charges, including domestic violence, simple battery, false imprisonment, tampering with evidence, and unlawfully moving a dead human body.
Abugharbieh made his first court appearance on the morning of April 25 and was ordered held without bond until his next detention hearing, scheduled for April 28 at 9 a.m. The case has drawn significant attention from legal experts and advocates, who are closely monitoring the proceedings. If convicted, Abugharbieh could face life in prison or the death penalty under Florida law.
Investigators have not yet released a motive for the killings, but reports suggest that Abugharbieh had been previously interviewed by police as part of the initial missing persons investigation. The sheriff’s office has not commented on whether Abugharbieh had any prior relationship with Bristy, though the two students were known to be in a romantic relationship.
Search Efforts Intensify as Second Set of Remains Found
The discovery of Limon’s remains on the Howard Frankland Bridge has led to an extensive search of the surrounding area, including the waters of Tampa Bay. On April 26, 2026, authorities confirmed that a second set of human remains had been recovered from a Pinellas County waterway, though they have not yet identified the remains or confirmed whether they belong to Bristy. The Pinellas County Sheriff’s Office is assisting in the recovery efforts, which have involved dive teams, sonar equipment, and aerial searches.
“We are doing everything in our power to bring Nahida home,” Maurer said during a press briefing. “Our teams are working around the clock, and we will not rest until we have answers for her family and the USF community.” The search has also drawn support from local volunteers, who have organized vigils and distributed flyers in hopes of generating new leads.
Despite the grim developments, the sheriff’s office has urged the public to remain hopeful. “We are treating this as a recovery mission, not just a recovery of remains,” Maurer said. “Our goal is to bring closure to the families of both students, and we are committed to seeing this through to the end.”
Families and Community Demand Justice
The deaths of Limon and Bristy have left their families and the broader USF community in mourning. In a statement released through their attorney, Limon’s family expressed their devastation and called for justice. “Zamil was a bright, kind, and driven young man who had his whole life ahead of him,” the family said. “We are heartbroken by this senseless tragedy and demand that those responsible be held accountable to the fullest extent of the law.”
Bristy’s family has also spoken out, urging authorities to prioritize the search for their daughter. “Nahida was a loving daughter, sister, and friend,” her family said in a statement. “We just want justice and accountability. Our hearts are broken, but we will not give up hope until we bring her home.” The families have requested privacy as they navigate this difficult time, but they have also expressed gratitude for the outpouring of support from the community.
The USF community has rallied around the families, organizing vigils and memorial services to honor the lives of Limon and Bristy. The university has also offered counseling services to students and faculty affected by the tragedy. “Our hearts travel out to the families of Zamil and Nahida during this unimaginable time,” USF President Rhea Law said in a statement. “We are committed to supporting our students and ensuring their safety on campus.”
The Broader Implications for International Students
The case has reignited conversations about the safety and well-being of international students in the United States. Both Limon and Bristy were from Bangladesh, and their disappearances have highlighted the unique challenges faced by students studying abroad, including cultural adjustment, language barriers, and the pressures of academic life. According to the Institute of International Education, there were over one million international students enrolled in U.S. Colleges and universities during the 2023-2024 academic year, with students from Bangladesh representing a growing demographic.
Advocates for international students have called for increased support systems, including mental health resources, cultural integration programs, and safety education. “This tragedy underscores the need for universities to prioritize the well-being of their international students,” said Jill Welch, senior policy advisor at the Presidents’ Alliance on Higher Education and Immigration. “These students often face unique stressors, and it is our responsibility to ensure they have the resources and support they need to thrive.”
The case has also drawn attention to the importance of campus safety measures. USF has stated that it is reviewing its protocols for reporting and responding to missing persons cases, as well as its support services for students in crisis. “We are committed to learning from this tragedy and taking steps to prevent similar incidents in the future,” Law said.
What Happens Next?
As the investigation continues, the next critical step in the legal process will be Abugharbieh’s detention hearing, scheduled for April 28, 2026. During the hearing, a judge will review the evidence and determine whether there is sufficient probable cause to proceed with the case. If the case moves forward, it will likely proceed to a grand jury, where prosecutors will present evidence to secure an indictment.
In the meantime, the Hillsborough County Sheriff’s Office has urged anyone with information about the case to come forward. Tips can be submitted anonymously through the sheriff’s office’s tip line or through the Crime Stoppers program. The sheriff’s office has also set up a dedicated hotline for the case, which can be reached at (813) 247-8200.
For the families of Limon and Bristy, the coming days and weeks will be filled with grief, uncertainty, and the long wait for justice. As the search for Bristy continues, the Tampa Bay community remains united in its determination to honor the memories of two young scholars whose lives were cut tragically short.
