Missing USF students: Suspect charged with two counts of first-degree murder

Tampa, Florida: The roommate of a USF doctoral student who went missing last week along with his friend has been charged with two counts of murder, authorities announced April 25. Hisham Abugharbieh, 26, is facing two counts of premeditated murder in the first degree with a weapon for the deaths of Zamil Limon and Nahida Bristy, both 27, the Hillsborough County Sherriff’s Office said.

Abugharbieh was arrested at his family’s Tampa home April. 25 following a standoff with authorities that resulted in the SWAT team’s assistance, but the charges did not include murder. Earlier in the day, the body of Zamil was discovered on the Howard Frankland Bridge. Bristy’s body has not been located.

“Evidence was presented to the State Attorney’s Office, resulting in further charges against Abugharbieh,” the sheriff’s office said in a statement. “At this time, the search for Bristy continues.”

In addition to murder, Abugharbieh is charged with domestic violence, tampering with evidence and unlawfully holding or removing a dead human body. He was interviewed by detectives April. 23, and after initially talking, he ended the interview and left. That was the same day authorities upgraded the case from missing to endangered.

Authorities were called to Abugharbieh’s family’s home for a domestic dispute about 9 a.m. April 24. Investigators were able to get relatives safely out of the home. Abugharbieh then barricaded himself inside and the SWAT team was called to assist. After about 20 minutes, Abugharbieh emerged from the home with his hands raised wearing no shirt and a blue towel around his waist.

“This is a deeply disturbing case that has shaken our community ad impacted many who were hoping for a safe resolution,” Sheriff Chad Chronister said. “While the discovery of Zamil Limon’s remains is heartbreaking, I want the public to know that our detectives are working tirelessly and relentlessly to uncover the truth.”

Limon and Bristy were last seen the morning of Thursday, April 16. A family friend reported both of them missing shortly before 5 p.m. April 17 after not being able to reach either of them. Both University of South Florida Police Department and Hillsborough County Sheriff’s Office documented and processed missing persons reports. Limon was pursuing a degree in geography, environmental science and policy while Bristy was studying chemical engineering.

Both families described Limon and Bristy as hardworking, dedicated, responsible students and said it was unusual for both to go days without talking to family members. They both had summer trips planned to their home country of Bangladesh. Abugharbieh is a U.S. citizen who previously took classes at USF from 2021 to 2023, according to a university spokesperson. He does have a criminal record including a 2023 charge of batter and burglary. Also that year, a relative filed two domestic petitions against him.
