Investigators cite suspicious AI-related querie
Florida suspect’s chilling AI searches reveal clues in USF double murder case as authorities in Florida say a suspect in the killings of two University of South Florida graduate students conducted alarming online searches about disposing of human remains days before the crimes, according to court filings.
Prosecutors allege that Hisham Abugharbieh, 26, used an artificial intelligence chatbot to ask about placing human remains in a dumpster and how such actions could be detected. The exchanges, detailed in a bail filing submitted on Saturday, April 19, 2026, included follow-up questions that raised concerns among investigators. Additional searches reportedly involved altering a vehicle identification number, firearm legality, and whether gunshots could be heard by neighbors.
Evidence recovered from apartment and nearby locations
Law enforcement officials say physical evidence linked to the case was recovered from multiple locations near Tampa, Florida. Items belonging to 27-year-old Zamil Limon, including identification and personal effects, were found in a dumpster near the apartment he shared with the suspect. Authorities also recovered cleaning supplies, trash bags, and clothing with blood traces.
Investigators later located human remains in a black plastic bag near the Howard Frankland Bridge. Court documents state that digital data placed the suspect at the bridge around 1:30 AM on Thursday, April 17, 2026, where he allegedly stopped for several minutes.
Missing person report and discovery of second victim
Limon and his girlfriend, Nahida Bristy, also 27, were reported missing on Thursday, April 17, 2026, after a friend was unable to reach them. While Bristy’s whereabouts were initially unknown, authorities later recovered additional human remains on Sunday, April 20, 2026. Identification efforts were ongoing at the time of the filing.
Arrest, prior history, and charges filed
Authorities said the suspect provided inconsistent statements before a search warrant was obtained for his phone. He later surrendered to police after barricading himself inside a residence for more than an hour on Friday, April 18, 2026.
Court records indicate a history of violent incidents involving the suspect, including prior charges of battery and burglary. He is currently held without bail at a detention facility near Tampa and faces multiple charges, including two counts of first-degree murder. Prosecutors have indicated he could face the death penalty if convicted.
