Investigators in Florida have uncovered alarming details in the murder of two Bangladeshi PhD students, Jamil Ahmed Limon and Nahida Sultana Brishti, who were last seen in Tampa about two weeks before Limon’s body was found. Police have arrested Limon’s roommate, Hisham Abughurbeh, charging him with premeditated murder using a weapon. A judge has ordered that he remain in custody without bail during trial proceedings.

Court filings show a detailed timeline of Abughurbeh’s actions before and after the killings, including purchases of duct tape, garbage bags, and lighter fuel, as well as disturbing ChatGPT queries about disposing of a body. Surveillance footage and phone data placed him near the victims’ last known locations. Evidence recovered from a landfill and a bridge linked him to the crime, including blood-stained items and a bag containing Limon’s remains.

Florida’s attorney general has added the case to an ongoing criminal investigation involving OpenAI, after prosecutors cited the suspect’s use of ChatGPT. OpenAI stated it is cooperating fully with law enforcement.
