A man who allegedly supplied his teenage niece with the handgun she later used to fatally shoot another teen she had feuded with on Facebook was convicted Saturday of murder, attempted murder and aggravated battery, a source confirms to PEOPLE.

After closing arguments Friday, a jury found Donnell Flora, 27, guilty the following morning.

Flora gave his teenage niece the gun after she had a dispute on Facebook with 14-year-old Endia Martin. In April 2014, he accompanied her to an in-person confrontation in Chicago’s Back of the Yards neighborhood, where she shot Endia dead outside a home.

Flora’s defense lawyers said their client never believed his niece would actually use the gun in the commission of a crime, and said he was just trying to protect his niece.

Flora’s lawyers intend to appeal the conviction and could file paperwork ahead of his next court hearing on Feb. 26.
