Human remains have been found in the waterways of Tampa Bay, where authorities have been searching for the body of missing University of Florida doctoral student Nahida Bristy, Florida deputies announced late Sunday as new court documents allege the suspect in the killing of Bristy and another student appeared to ask ChatGPT how to dispose of a body.
The remains were found in Pinellas County and have not yet been identified. According to the Hillsborough County Sheriff's Office, the remains were found "in the area of Interstate 275 and 4th Street North," which is at the St. Petersburg side of the Howard Frankland Bridge.
Bristy, 27, who is presumed dead, went missing last week along with 27-year-old Zamil Limon, whose remains were found Friday on a bridge near Tampa. Limon's roommate, 26-year-old Hisham Abugharbieh, was arrested Saturday and is charged with two counts of premeditated first-degree murder with a weapon. He is being held without bond.
Court documents unveiled Sunday reveal Abugharbieh allegedly asked ChatGPT questions about how to dispose of a body in the days leading up to the disappearance of Brsity and Limon.
According to the documents, the suspect asked ChatGPT on April 13 what would happen if someone was "put in a black garbage bag and thrown in dumpster." The AI chatbot responded that it sounds dangerous, prompting Abugharbieh to allegedly ask, "How would they find out."
