New report details suspect's worsening behavior before USF students were killed

Hisham Abugharbieh, accused in the deaths of two missing USF students, is seen during his arrest on April 24, 2026.

Family members say the behavior of a suspect in the slayings of two USF students worsened over time because of marijuana use, according to an incident report from a 2023 arrest.

The behavior of a suspect in the killing of two University of South Florida students from Bangladesh worsened over time from marijuana use, family members told deputies after his arrest three years ago for punching his brother in the face and kicking his mother in the back.

Hisham Abugharbieh was delusional at the time, stating “I am son of Mary” and “I created my brother. I am his god." He was taken to jail under the Baker Act, a Florida law that allows for involuntary, emergency mental health observation for 72 hours, according to an incident report made public Wednesday about the May 2023 misdemeanor battery arrest from the Hillsborough County Sheriff's Office.

“Hisham used to be a cool guy, a supportive and helpful eldest son, until he started smoking cannabis, especially medical marijuana,” a relative whose name was redacted wrote in a victim impact statement more than a week after Abugharbieh's May 2023 arrest. “It turned him mentally ill, with hurtful behavior and anger problems which is affecting the family life. We lost Hisham as a normal family member.”

At the time, Abugharbieh told deputies that he was acting in self-defense because his brother was threatening him. Abugharbieh's relatives didn't want him to face prosecution but asked that he receive substance abuse treatment.

Last week, Abugharbieh, 26, was charged with two counts of first-degree murder for the killings of two USF doctoral students. He is being held without bond.

The remains of Abugharbieh’s roommate, Zamil Limon, were found in a trash bag on the Howard Frankland Bridge last Friday. On Sunday, the sheriff’s office announced that a body had been found in a waterway near the bridge, but the local medical examiner's office hasn't publicly confirmed it to be Limon’s girlfriend, Nahida Bristy.

Nahida Bristy and Zamil Limon disappeared from the USF Tampa campus on April 16.

They disappeared April 16. Limon was last seen at the off-campus apartment complex where he lived with Abugharbieh, and Bristy at a campus science building. Limon was studying geography, environmental science and policy, and Bristy was studying chemical engineering.

Reached by email earlier this week, Jennifer Spradley, an attorney in the public defender’s office in Tampa, said the office wouldn’t comment on Abugharbieh’s case.

Abugharbieh was arrested last Friday after he barricaded himself inside his family's home and refused to come out, following the arrival of law enforcement for what authorities described as a report of domestic violence. One of the police reports released Wednesday said that he had grabbed his sister and held her against her will before she was able to break free. Abugharbieh faced misdemeanor battery and felony false imprisonment charges from the incident.

Since the slayings, a petition was posted "asking serious questions about off-campus housing safety, roommate concerns, and complaint handling."

In addition to asking for changes at Limon's off-campus apartment, petition organizers are calling on USF to review how off-campus housing options are presented to students. They also want USF to set basic eligibility standards for which off-campus properties may appear on "USF-facing student housing resources" and more.

“I want to assure you that the university is reviewing all factors involved, including conditions and safety measures that are in place at off-campus housing facilities,” Limayem said. “While USF does not own, operate or manage off-campus apartments, we recognize the importance of the safety and well-being of our students wherever they live.”

Limayem also said that the university would hold a vigil for Limon and Bristy on Friday, and that there would be a remembrance for the students during next week's commencement ceremonies. A fund to support the students' families also was started privately, and there also will be moments of silence for them during sporting events this week, Limayem said.
