Core Event
On April 24, investigators found Zamil Limon, 27, in a black trash bag on the Howard Frankland Bridge; on April 26, a second bag in mangrove wetlands near I-275 contained Nahida Bristy, 27, also from Bangladesh. DNA, dental records and clothing confirmed both identities.
Timeline
April 16 – Limon seen at 9 a.m. in his Avalon Heights apartment and Bristy at noon on campus; later that night suspect Hisham Abugharbeih moved boxes.
April 24 – Limon’s body recovered; Abugharbeih arrested after a domestic-violence call.
April 26 – kayakers discovered Bristy’s bag.
End-April – DNA testing confirmed Bristy’s identity; sheriff held a press conference.
Key Figures & Data
Victims: Nahida Bristy, USF doctoral student in chemical engineering; Zamil Limon, Ph.D. candidate in geography, environmental science and policy.
Suspect: Hisham Abugharbeih, 26, former roommate and former USF management student, charged with two counts of first-degree premeditated murder, two counts of unlawful body disposal, and one count each of false imprisonment, battery, tampering with evidence and failure to report a death. Both victims were 27.
Impact & Official Statements
Campus vigils and a university-fund for the families followed the killings, prompting scrutiny of off-campus housing safety and AI misuse after investigators found the suspect queried ChatGPT about body disposal. Sheriff Chronister described the case as a “monstrous crime” and expressed community heartbreak; President Limayem called the loss “profound sadness” and pledged a housing-safety review; State Attorney Lopez ordered the suspect held without bond; Attorney General Uthmeier announced a probe into OpenAI.
Criticism & Opposition
Investigators highlighted the suspect’s pre-meditated actions—purchasing heavy-duty trash bags, Lysol wipes and searching online for disposal methods—indicating a calculated plan; family members and university officials criticized the lack of earlier intervention despite prior complaints about Abugharbeih’s violent behavior.
On-the-Ground Reports
Two kayakers snagged a line on a bag in mangrove wetlands, reported an “indescribable” odor and alerted authorities; luminol testing at the suspect’s apartment revealed blood in a fetal-position outline, and forensic analysis matched Bristy’s DNA and dental work while Limon’s identity was confirmed via fingerprints.
Conflicting Reports & Gaps
Authorities have not disclosed Bristy’s cause of death and the motive for both killings remains unknown; reports differ on whether the victims were romantically involved, describing them variously as friends, a couple, or simply classmates.
