Hisham Abugharbieh, the 26-year-old accused of murdering two University of South Florida doctoral students, Zamil Limon and Nahida Bristy, both 27, is being held without bond. Prosecutors allege that he asked ChatGPT about putting someone in a dumpster on the night of April 13, three days before they were last seen alive. The move was supported by a motion filed by the court seeking to keep him behind bars while he awaits trial. The remains of Limon, who was found Friday, have not been identified. Prosecutors have not specified what may have motivated the killings.
