A former University of South Florida student has been charged with killing his roommate and the roommate’s girlfriend — two doctoral students from Bangladesh who disappeared earlier this month, authorities said Saturday.
Hisham Abugharbieh, 26, is facing two counts of premeditated murder in the first degree with a weapon in the deaths of Zamil Limon and Nahida Bristy, students at USF, according to the Hillsborough County Sheriff’s Office.
Limon’s remains were found on the Howard Frankland bridge Friday morning, but Bristy is still missing, Hillsborough County Chief Deputy Joseph Maurer said on Friday.
However, Bristy’s brother has claimed that his sister has also died.
“Our sister is no longer with us. Inna lillahi wa inna ilaihi raji’un,” her brother, Zahid Hasan Pranto, said in a Facebook post on Saturday.
Abugharbieh, a native-born U.S. citizen, was initially taken into custody on Friday at his family’s home on preliminary charges that include unlawfully moving a dead body, failure to report a death, tampering with evidence, false imprisonment and battery.
Officers encountered Abugharbieh as they responded to a report of domestic violence at his family’s home, just north of the campus, and were able to move his relatives to safety. But then he barricaded himself inside and refused to come out. A SWAT team responded — along with a drone, a robot and crisis negotiators — before Abugharbieh came out with his hands up, apparently wearing nothing but a blue towel.
Limon and Bristy, both 27, were considering getting married, a relative said. They disappeared from campus on April 16. Limon was last seen at his home in an off-campus apartment complex where he lived with Abugharbieh. Bristy, who lived on campus, was last seen an hour later at a campus science building.
An autopsy is being done on the remains to determine the manner and cause of Limon’s death, and those results are expected Saturday morning, Maurer said Friday.
Abugharbieh had been a USF student but was not currently enrolled. University records showed he had attended the school from Spring 2021 through Spring 2023, and had pursued a BS in Management, a university spokesperson said.
Limon was studying geography, environmental science and policy, and Bristy was studying chemical engineering. She was a graduate of Noakhali Science and Technology University. The school, which spelled her last name as Brishti, said in a statement Saturday that she was a Ph.D. candidate and described her as a talented and promising student.
“Her sudden passing has deeply saddened all of us,” Vice Chancellor Mohammad Ismail said. “The university family pays deep respect to her memory. At the same time, we demand punishment for those involved in her death and compensation for the victim’s family.”
The search for Bristy continues. Anyone with information regarding her disappearance is asked to contact the Hillsborough County Sheriff’s Office.
Abugharbieh had several previous arrests, the sheriff’s office said. He was charged with battery and burglary of an unoccupied dwelling in September 2023, and with battery that May — both classified in court records as misdemeanors.
Court records show Abugharbieh entered into a diversion program for first-time offenders charged with misdemeanors. He completed the program in 2024 and the charges were discontinued. A phone call to his lawyer in that case was not immediately returned.
Hillsborough County Court records also showed two domestic violence petitions filed by a family member in 2023. A judge granted an injunction in one case and denied the other petition. He also was accused of traffic violations.
