But after one of those incidents, his brother filed for an injunction that prohibited Abugharbieh from coming near him or his home. In court filings, the brother alleged Abugharbieh attacked him and his mother during an argument in which the brother was telling him to get out of the house.When the injunction expired last May, the brother asked the court to extend it, saying he did not want to \u201crun the risk of him returning.\u201d His request was denied.The suspect had attended USF between 2021 and 2023 while he pursued a bachelor\u2019s degree in management, a spokesperson for the university told CNN.\u2018We are becoming numb,\u2019 student\u2019s brother saysThe students had been missing since last week, prompting friends in Florida and relatives in Bangladesh to look for answers.Before Limon\u2019s body was found, his brother told CNN the family was in \u201cdeep pain\u201d awaiting news.\u201cIt\u2019s devastating for us,\u201d Zubaer Ahmed said.
