A Florida man, Hisham Abugharbieh, is accused of murdering University of South Florida students Zamil Limon and Nahida Bristy after they were reported missing, with police alleging the killings were premeditated. Investigators say his suspicious behavior, shifting stories, physical injuries, and alleged disturbing online searches, including questions to ChatGPT about disposing of bodies and evading detection, helped build the case against him. Authorities later found Limon’s body and evidence of a violent crime, and Abugharbieh was arrested after a SWAT standoff, now facing two counts of first-degree murder while Bristy remains missing but presumed dead.
