The Hillsborough County Sheriff’s Office confirmed Friday that human remains recovered from Tampa Bay belong to Nahida Bristy, a 27-year-old doctoral student at the University of South Florida who vanished last month alongside a fellow graduate student.
Bristy and Zamil Limon, both pursuing advanced degrees at the university, were last seen in the Tampa area on April 16. The discovery of Limon’s body one week ago, found in multiple black plastic bags on the Howard Frankland Bridge spanning Tampa Bay, set off an intensive search operation that culminated in the recovery of Bristy’s remains from the bay’s waterways this past Sunday.
Sheriff Chad Chronister stated that investigators utilized DNA analysis, dental records, and clothing Bristy wore prior to her disappearance to make a positive identification. The sheriff did not disclose the condition of the remains or provide details regarding the cause of death for either victim. Dive teams participated in the extensive search efforts throughout the week.
The investigation has led to the arrest of Hisham Abugharbieh, 26, who shared living quarters with Limon. Abugharbieh faces two counts of first-degree murder, along with charges of battery, false imprisonment, tampering with evidence, failure to report a death, and unlawfully moving a body. He remains in custody without bond.
Court documents reveal troubling details about Abugharbieh’s actions in the days preceding the students’ disappearance. According to these records, he allegedly consulted the artificial intelligence program ChatGPT with inquiries about methods for disposing of a human body. This digital evidence has become a critical component of the prosecution’s case.
Ahmad Abugharbieh, the suspect’s younger brother, informed authorities that family members had previously contacted police regarding his brother’s increasingly erratic behavior. Court records indicate that Hisham Abugharbieh had become estranged from his family in recent months.
The Bristy family had been notified earlier this week by law enforcement that their daughter was likely deceased, even before formal identification occurred. Sheriff Chronister confirmed that the family has now been officially informed of the identification.
This tragedy has sent ripples of concern through the University of South Florida community, where both victims were working toward their doctoral degrees. The loss of two promising young scholars under such violent circumstances raises questions about student safety and the university’s awareness of potential threats within its graduate student population.
The investigation remains active as authorities work to establish a complete timeline of events and determine the precise circumstances that led to these deaths. Law enforcement officials have not indicated whether they are seeking additional suspects in connection with the case.
As this case proceeds through the judicial system, the focus now turns to ensuring justice for Bristy and Limon while their families and academic community begin the difficult process of mourning two lives cut tragically short.
