Surveillance footage of a gunman walking up behind a security guard and shooting him at point-blank range in the head, killing him, has been released.

The incident happened in Atlanta on Monday (April 18) when Anthony Frazier, 51, got out of his vehicle to walk inside of American Seafood and Wings on Cleveland Avenue where he worked as a guard. The gunman is seen walking up behind Frazier, pulling a gun from his pocket, shooting him in the head, and then robbing Frazier. 

As Frazier lay dead on the sidewalk, the gunman walks past a witness who watched the incident unfold. The witness held their hands in the air as the gunman continued to walk away from the scene. Three others appear to have come upon Frazier's body and stole from him as he was on the ground.

On Wednesday, Stanley Henderson, 31, was arrested in connection with the shooting after giving chase to officers on foot. He was found in an "urban encampment" where they believe he had been living. Henderson has been charged with felony murder and two counts of aggravated assault.
