A man has been charged with two counts of first-degree murder in the deaths of University of South Florida students Zamil Limon and Nahida Bristy, who disappeared from the Tampa campus earlier this month, according to reporting from Lex 18 News.

Hisham Abugharbieh, 26, was charged Saturday by the Hillsborough County Sheriff's Office in connection with the deaths of the two doctoral students. Limon's remains were discovered Friday morning on the Howard Frankland Bridge, while Bristy remains missing.

Abugharbieh, a U.S. citizen, was taken into custody Friday at his family's home following a domestic violence call. He barricaded himself inside the residence before a SWAT team with a drone, robot and crisis negotiators convinced him to surrender with his hands raised.

The 27-year-old Limon and Bristy, also 27, disappeared April 16 from the USF campus. Limon was last seen at his off-campus apartment where he lived with Abugharbieh, while Bristy was spotted an hour later at a campus science building. According to a relative, the couple was considering marriage.

Abugharbieh initially faced preliminary charges including unlawfully moving a dead body, failure to report a death, tampering with evidence, false imprisonment and battery. An autopsy on Limon's remains was expected to determine the cause and manner of death.

Abugharbieh was a former USF student who attended from spring 2021 through spring 2023, pursuing a degree in management, according to university records. He was not currently enrolled at the time of the incident. Limon was studying geography, environmental science and policy, while Bristy was pursuing chemical engineering.

Court records show Abugharbieh had previous arrests, including charges for battery and burglary of an unoccupied dwelling in September 2023, and battery in May of that year. Both were classified as misdemeanors. He completed a diversion program for first-time offenders in 2024, and those charges were discontinued. Hillsborough County records also showed two domestic violence petitions filed by a family member in 2023, with one resulting in an injunction.

The search for Bristy continues. Anyone with information is urged to contact the Hillsborough County Sheriff's Office.
