The essentials
Physical evidence, digital searches, and autopsy findings built the murder case against the arrested suspect.
Physical evidence from Hisham Abugharbieh's apartment directly linked him to both victims, according to investigators. Police discovered victim's belongings and blood evidence during searches of the suspect's residence, establishing forensic connections to Zamil Limon and Nahida Bristy, two USF doctoral students reported missing on April 16.
The arrest followed a domestic violence incident reported near the USF campus, which escalated to a suspect barricade situation. Subsequent investigation revealed the suspect purchased items consistent with body disposal prior to the students' disappearance, a detail prosecutors argue demonstrates premeditation. Medical examination confirmed one victim died from multiple stab wounds, establishing cause of death through autopsy findings.
Digital forensics revealed the suspect searched ChatGPT for body disposal methods before the disappearance date. The convergence of physical evidence, autopsy findings, timeline-specific purchases, and digital searches formed the investigative foundation that authorities used to escalate charges from initial evidence tampering allegations to two counts of first-degree murder. A grand jury subsequently indicted Abugharbieh, and prosecutors announced they will seek the death penalty, marking a significant escalation in legal proceedings.

Forensic evidence pathway builds from discovery to indictment
Physical evidence and blood from the suspect's apartment provided the evidentiary foundation for escalating charges. Autopsy findings confirmed stab wounds as cause of death, while purchases consistent with body disposal prior to April 16 established timeline specificity. Digital searches for body disposal methods added premeditation indicators. This convergence of forensic, autopsy, and circumstantial evidence guided investigators from initial evidence tampering charges to two counts of first-degree murder, culminating in grand jury indictment.
Escalating charges reflect evidence strength through procedural stages
The suspect progressed through distinct legal phases beginning with evidence tampering and failure to report death charges following arrest at a domestic violence incident. Physical evidence, blood samples, and autopsy findings supported elevation to first-degree murder charges. Digital forensics showing body disposal searches strengthened the prosecution's case. The grand jury's formal indictment represented procedural validation of accumulated evidence, with prosecutors subsequently announcing death penalty pursuit, indicating their assessment of case severity for capital charges.
