Roger Fortson was killed by a deputy in May

The death of Andre comes as the family is grappling with the death of Fortson in early May. Eddie Duran, who was terminated from the Okaloosa County County Sheriff's Office, was identified as the deputy involved.

On May 3, Duran responded to a Fort Walton Beach apartment complex after receiving a call about an apparent disturbance.

Duran's body camera footage shows that he knocked on Fortson's apartment door three times and announced he was with the sheriff's office. Fortson opened the door while holding a gun in his right hand and pointed down. The deputy said, "step back," and then shot Fortson.

"I want justice for my child. You're not going to throw me a bone. Take his credentials. Take his pension," his mother, Chantemekki Fortson, said at a news conference.

During the investigation, the sheriff's office found that Duran's use of force "was not objectively reasonable and therefore violated agency policy."

Fortson's body was delivered to his family in Atlanta prior to his funeral.
