The video begins like many others that erupt into mass violence: a young man in a car, holding a gun.
Recorded in the style of a first-person shooter game, the video appears to show the perspective of one of the gunmen who killed three people Monday at the Islamic Center of San Diego as he storms the mosque, opens fire and steps over a fallen body. At the video’s end, the camera records the gunman raising a pistol to his chin, then slumping forward in a torrent of blood.
