This other thread about the slain officer's widow says his widow was told by the police that Taylor was in the process of exiting the passenger side door of his vehicle at the moment he was shot. My theory, taking into account that Taylor, as the local police assisting the Highway Patrol on this high speed chase, was sitting in the driver's seat of his vehicle, with the vehicle in drive and his foot on the brake when Matthews got out of his vehicle and approached the driver's side of Taylor's vehicle. Matthews then pulled out his weapon, and in the split second Taylor had to realize what was going on before the fatal shot was fired, Taylor was made a dive away from Taylor when he was shot from behind. Taylor did manage to get out, or fall out, of the vehicle, which had started moving the moment he took his foot off the brake and continued to roll.
