Prosecutors have revealed significant new evidence in the investigation into the deaths of two University of South Florida students, including alleged searches on ChatGPT regarding body disposal and purchases of disposal materials.
Charges and Investigation Status
The charges against Hisham Abugharbieh, Limon’s roommate, are severe. He has been formally charged with two counts of first-degree premeditated murder with a weapon in the deaths of Zamil Limon and Nahida Bristy, both 27.
- Missing Student: Nahida Bristy remains missing as authorities continue to identify additional human remains recovered south of the Tampa Bay bridge.
- Legal Proceedings: Abugharbieh is scheduled for a pretrial detention hearing on Tuesday. The Hillsborough County Public Defender’s Office declined to share details, citing his right to a fair trial.
Details of the Victims and Crime Scene
Zamil Limon, a student from Bangladesh at USF, was found deceased on the northbound Howard Frankland Bridge in Tampa Bay. A court document filed Saturday detailed that Limon died from “multiple sharp force injuries.”
- Cause of Death: The medical examiner’s report cited a deep stab wound to his lower back that penetrated his liver, among other injuries.
- Disposal: Limon’s body was discovered on the bridge shoulder on Friday. Authorities believe Bristy was disposed of in a manner similar to Limon.
Alleged Digital and Physical Evidence
Prosecutors have highlighted several pieces of evidence suggesting premeditation and attempts to conceal the crime.
ChatGPT Communications
Prosecutors allege Abugharbieh used ChatGPT in the days leading up to the students' disappearance to inquire about disposing of a body. Specific queries cited include:
- “What happens if a human has a put in a black garbage bag and thrown in a dumpster?” (Asked April 13th)
- Follow-up questions regarding how the disposal would be discovered.
- Inquiries on April 15th regarding the legality of keeping a gun without a license and changing a car’s VIN number.
- Later searches included questions about sniper bullet survival and water temperatures that cause immediate burns.
Purchases and Found Items
Evidence gathered includes:
- Purchases: Abugharbieh reportedly ordered duct tape, trash bags, lighter fuel, fire starter, and charcoal from Amazon in the week before the killings. A purchase confirmation also showed a fake beard shipped on April 15th.
- Forensic Findings: Items recovered from a dumpster included Limon’s student ID, credit cards, and eyeglasses. Lab testing linked profiles from a gray shirt to Limon, and a floor mat to Bristy.
- Scene Evidence: An enhancement agent found a broad pattern of blood in the apartment, leading into the hallway and toward Abugharbieh’s bedroom, where two distinct, human-sized smearing patterns were found on the carpet.
- Personal Effects: Bristy’s sneakers and umbrella, consistent with campus surveillance footage, were found in Limon’s bedroom, alongside a coin purse containing her USF ID and credit cards.
Suspect's Evolving Statements
Investigators noted significant inconsistencies in Abugharbieh’s statements to detectives:
- Initially, he claimed he had not seen the pair on the day they went missing.
- He later changed his story regarding his vehicle’s location, initially denying being in Clearwater, and later claiming Limon had asked to be driven there with his girlfriend.
- During interviews, his left pinky finger was bandaged, a wound he claimed was self-inflicted while cutting onions.
Additional Charges and Next Steps
Beyond the two counts of first-degree murder, Abugharbieh faces charges including unlawfully moving a dead body, failure to report a death with intent to conceal, tampering with physical evidence, false imprisonment, and battery. Sheriff Chad Chronister described the case as “deeply disturbing.”
