After the supervisor, identified as Sgt. Colin Langsdale, saw the man on the sidewalk, he stopped his car, got out and observed the suspect pointing the bike — that he believed to be a gun — at him. Langsdale then fired his service weapon, striking the man, and the man fell to the ground.

The man was taken to Ronald Reagan UCLA Medical Center where he later died from his injuries.
