Remains found in Pinellas County, Fla., during search for USF student
April 27 (UPI) -- Human remains have been found in Pinellas County, Fla., as investigators search for a second missing University of South Florida doctoral student.
The remains were found in a Tampa Bay waterway on Sunday night as authorities searched for the body of Nahida Bristy, a 27-year-old student from Bangladesh who has been missing for about a week. The remains have not been identified.
The body is with the Pinellas County Medical Examiner's Office.
On Saturday, 26-year-old Hisham Abugharbieh, 26, was charged with two counts of first-degree premeditated murder with a weapon in the deaths of Bristy and Zamil Limon, 27, a roommate of Abugharbieh. Limon's body was found on Friday on the Howard Frankland Bridge in Tampa Bay.
Court documents unveiled Sunday say that Abugharbieh used ChatGPT to find information about how to dispose of a body ahead of the disappearances of Bristy and Limon. His queries included a search on April 13 about what would happen if someone was "put in a black garbage bag and thrown in a dumpster."
Limon's body was discovered in "numerous black utility trash bags in advanced stages of decomposition," court documents say.
The Pinellas County Examiner's Office autopsy of Limon's body found multiple stab wounds and lacerations. His death was ruled a homicide due to "multiple sharp force injuries."
Investigators discovered "significant" blood patterns in Limon and Abugharbie's apartment, court documents say.
