This is a murder case that has sent chills down the spines of the international student community and the entire neighborhood. “What would happen if you put a person in a black garbage bag and threw it in the trash?” A 26-year-old man in Florida asked ChatGPT this question four days before committing a murder. Four days later, his roommate’s body was discovered, wrapped in several layers of black industrial waste bags, and dumped on the cross-sea bridge.
Another missing female doctoral student remains at large. The incident occurred in Tampa, Florida. Both victims were Bangladeshi international students and doctoral students at the University of South Florida (USF). Zamil Limon, 27, majoring in Geography and Environmental Policy, and Nahida Bristy, 27, a PhD in Chemical Engineering, are a couple. The murder suspect is Hisham Abugharbieh, 26, who was Limon’s roommate. The court documents released by the police are full of details. On April 7th, Abu Gabi bought a roll of tape from Amazon.
On April 11th, he placed an order for a batch of garbage bags and lighter fluid. On April 13, he opened ChatGPT and asked the question he started with. The AI replied, “That sounds dangerous.” He followed up, “So how will they find out?”
On April 15, the day before the two disappeared, he asked a series of dangerous questions: “Can a car’s VIN code be changed?”, “Can I fire a gun at home without a license?” Early on April 17, another search result appeared: “Will cars parked in Hillsborough River State Park be checked?” That night, his phone’s location was pinpointed precisely to the bridge where the body was later dumped.
On Friday, April 24, a passerby discovered Lemon’s body near the Howard Frankland Bridge across Tampa Bay. The forensic doctor’s description was restrained, yet every word sent shivers down one’s spine: the body was stuffed into several layers of black industrial waste bags, already highly decomposed, covered in knife and laceration wounds. The cause of death was “multiple sharp force injuries,” classified as homicide.
Police recovered human remains from the St. Petersburg side of Tampa Bay. The remains have been handed over to the Pinellas County Medical Examiner’s Office for identification. Police have made it clear: she was most likely murdered, and the case was handled in the same manner as her boyfriend’s. Her brother wrote on social media that his sister “is no longer here,” and that she was always smiling and had a cheerful personality.
Police stormed into the shared apartment with a search warrant. Using fluorescent brighteners, bloodstains could be seen running from the entrance hall to the kitchen, then into the hallway, and finally to Abu Gabi’s bedroom.
Even more disturbingly, there were two clear bloodstains on the bedroom floor, roughly the size of a human body. Downstairs in the garbage compactor, police found Bristy’s pink phone case, Limon’s wallet, and glasses.
Under Abu Gabi’s bed were three rolls of heavy black garbage bags, the same as the ones used to wrap Limon’s body, and the duct tape was in his bathroom. He was at his parents’ house on the day of his arrest. Police confronted him for a while outside a residence in Lutz, and when he was finally put into a police car, he was only wrapped in a towel.
The charges are long: two counts of premeditated murder (with a deadly weapon), unlawful disposal of a body, failure to report a death, tampering with evidence, unlawful detention, and domestic violence assault. He is currently denied bail. Police have not yet released the motive. One detail is quite intriguing: Bristy’s USF student ID and credit card were found in Lemon’s bedroom. She had gone to her boyfriend’s place on the evening of April 16, and the two of them never came out again. Abu Gabi himself also had multiple wounds on his legs, and court documents say he repeatedly changed his testimony in the face of electronic evidence.
Hillsborough County Sheriff Chad Chronister described the case in one word: “deeply disturbing.” The USF campus is in an uproar; this is the ending for a doctoral couple studying abroad. As for the man who chatted with the AI about “how to dispose of the body,” his next court appearance is scheduled.
