A former student of the University of South Florida has become the central figure in the investigation into the death of Bangladeshi doctoral student Zamil Limon and missing of Nahida Bristy.
Police have taken Hisham Saleh Abugharbeih, 26, into custody.
He had been living with Limon and was previously enrolled at the university but was not a student at the time of his arrest.
Investigators said inconsistencies during questioning and his proximity to the victims led to heightened suspicion.
Authorities later said they were able to link him to the case and to the recovery of Limon’s body.
Limon’s remains were found on the Howard Frankland Bridge, while search efforts continue for Bristy, who remains missing.
Law enforcement officials said the suspect had been interviewed multiple times and initially cooperated before ending communication with investigators.
Authorities also pointed to his past legal record, which includes previous arrests on battery-related charges and domestic violence complaints filed by a family member.
He was detained after officers responded to a domestic violence call at a residence near the campus.
Police evacuated family members before he barricaded himself inside. A SWAT team was deployed, and he later surrendered.
The suspect now faces several charges, including battery, false imprisonment, tampering with evidence and unlawfully moving a body.
Officials said he has not yet been formally charged in connection with Limon’s death.
According to investigators, both Limon and Bristy had been missing since April 16.
Bangladesh’s embassy in Washington has described the incident as deeply distressing, while authorities in Florida continue coordinated efforts to locate Bristy and determine the full circumstances of the case.
