Human remains were discovered in Tampa Bay waterways during the search for missing University of South Florida doctoral student Nahida Bristy. Her presumed killer, Hisham Abugharbieh, faces two counts of first-degree murder for the deaths of Bristy and roommate Zamil Limon. Court documents reveal Abugharbieh queried ChatGPT on body disposal methods before the pair vanished.
Authorities announced late Sunday the discovery of unidentified human remains in Pinellas County near Interstate 275 and 4th Street North, on the St. Petersburg side of the Howard Frankland Bridge. The search focused on Nahida Bristy, 27, who disappeared last week alongside Zamil Limon, 27, whose decomposed body was found Friday inside black trash bags on the same bridge. An autopsy confirmed Limon's death as a homicide from multiple sharp force injuries including stabs and lacerations, according to court documents unsealed Sunday. Abugharbieh, 26, Limon's roommate, was arrested and charged Saturday with two counts of premeditated first-degree murder with a weapon; he remains held without bond and is due in court Tuesday. He sustained lacerations on his legs, investigators noted. Detectives found significant blood patterns in the shared apartment, from the foyer through the kitchen, hallway, and into Abugharbieh's bedroom, where two human-sized shapes appeared on the floor after using an enhancement agent. Court records show Abugharbieh asked ChatGPT on April 13 about disposing a body in a black garbage bag in a dumpster, followed by queries on April 15 about changing a car's VIN and keeping a gun without a license. On April 17, just after midnight, he inquired about vehicle checks at Hillsborough River State Park; his phone pinged that night at the bridge location where Limon's remains were found. Prosecutors believe Bristy was disposed of similarly. Ahmad Abugharbieh, 22, the suspect's brother, told CBS News the family had warned police of Hisham's erratic behavior, including past violence like punching him and screaming he was God. The family filed protective orders in 2023, granted, and 2025, denied. State Attorney Suzy Lopez stated Abugharbieh remains a danger to the community and expressed sympathy to the victims' families.
