The killing is reminiscent of an unannounced police raid in Louisville, Kentucky, in March 2020, when police burst into the apartment of Breonna Taylor, a 26-year-old Black woman who was an emergency medical technician, killing her. Police had obtained a "no knock" warrant to raid the apartment, mistaking it for the home of a suspect.

A Florida county sheriff on Thursday released body-camera video of a deputy fatally shooting a Black airman who had a handgun at his side in his apartment, after civil rights attorney Ben Crump, who represents the family, urged officials to release it.

The family of the deceased, Roger Fortson, 23, has insisted the deputy, who was investigating a domestic violence complaint, knocked on the wrong door on May 3.

The video shows Fortson opening the door and holding a handgun at his side and pointed down. The deputy immediately opens fire multiple times at close range. Fortson later died in the hospital.

"It is very troubling that the deputy gave no verbal commands and shot multiple times within a split second of the door being opened, killing Roger," the family said in a statement released by Crump, who represents them.

"We remain adamant that the police had the wrong apartment as Roger was on the phone with his girlfriend for a substantial amount of time leading up to the shooting, and no one else was in the apartment," the family statement said.

Police had obtained a "no knock" warrant to raid the apartment, mistaking it for the home of a suspect.

Taylor's death, along with the killing of George Floyd by Minneapolis police weeks later, set off a worldwide wave of protests against racism in law enforcement in the summer of 2020.

Okaloosa County Sheriff Eric Aden said in a statement the unidentified deputy was responding to a call of a disturbance in progress when he encountered an armed man and fired.

The deputy was placed on administrative leave while the Florida Department of Law Enforcement investigates and the

the State Attorney's Office conducts an independent review, Aden said.

"What we do know at this time is that the deputy did announce himself, not once but twice," Aden told reporters on Thursday upon releasing the video.

"The deputy knocked on the correct door. He did not cover the peephole or otherwise obscure its view," Aden said, adding that he believes Fortson knew that law enforcement was at the door when he answered with a gun in his hand.

The body-camera video records the deputy twice saying "sheriff's office, open the door."

It remained unclear who called law enforcement on the day of the shooting or why.
