Recently revealed court documents indicate that Hisham Saleh Abugharbieh, a 26-year-old accused of murdering two doctoral students from the University of South Florida (USF), consulted ChatGPT three days prior to the crime to inquire about disposing of a body using black garbage bags and dumping it in a dumpster.
According to records presented by prosecutors, this inquiry was made on April 13, 2026, and is seen by authorities as direct evidence of premeditation in the double homicide.
The documented questions also include scenarios about the possibility of surviving a gunshot to the head and whether neighbors might hear gunfire, highlighting a meticulous plan for the attack.
The victims, Zamil Limon and Nahida Bristy, both 27 and originally from Bangladesh, were pursuing doctoral programs at USF and were last seen on April 16, 2026.
Abugharbieh was Limon's roommate at the Avalon Heights Boulevard residential complex in Tampa. He was apprehended after barricading himself in his family's home in the Lake Forest neighborhood, surrendering peacefully to a SWAT team clad only in a blue towel.
Limon's body was discovered under the Howard Frankland Bridge in Tampa, wrapped in multiple heavy-duty black garbage bags, and showed multiple stab wounds per the autopsy.
On the previous Sunday, human remains were found near the same bridge in Tampa Bay's waterways. Authorities suspect these belong to Bristy, although official identification is still pending.
Court documents further reveal that on the night of April 16, a witness saw Abugharbieh moving cardboard boxes to the apartment complex's dumpster, claiming he was discarding old clothes.
That same night, the suspect purchased garbage bags, duct tape, cleaning supplies, and air fresheners. His phone signaled at the Howard Frankland Bridge, the location where Limon's remains were later found.
Significant blood was found in the shared apartment's foyer, kitchen, hallway, and bedroom, and in the complex's trash compactor were Limon's wallet, glasses, credit card, university ID, Bristy's pink phone case, and clothing with both victims' DNA.
The prosecution's motion filed in court asserts that "evidence will show Hisham Abugharbieh used a sharp instrument to fatally wound Zamil Limon and Nahida Bristy multiple times, leading to their deaths."
A family member of the accused informed investigators that Abugharbieh "was known for struggling with anger management and had been violent with family in the past," with court records showing a protection order filed by his own brother in 2023.
Abugharbieh was formally charged last Saturday with two counts of first-degree murder with a weapon and remains in custody without bail, also facing charges for illegal handling of a human body, evidence tampering, and false imprisonment.
This case unfolds amid growing concern in Florida about the usage of artificial intelligence in crime planning: State Attorney General James Uthmeier launched a formal investigation against OpenAI on April 10 due to ChatGPT's alleged connection to the 2025 Florida State University shooting, wherein the attacker had over 270 conversations with the chatbot before the incident.
In Florida, premeditated first-degree murder is a capital offense that may result in the death penalty or life imprisonment without parole, though prosecutors have yet to decide whether they will pursue capital punishment in this case.
