Gunman kills 12 in Denver shooting at "Batman" movie;
A lone gunman dressed in riot gear burst into a movie theater in Aurora, Colo., at a midnight showing of the Batman film "The Dark Knight Rises" and methodically began shooting patrons, killing at least 12 people and injuring at least 50.
Witnesses in the movie theater said Holmes crashed into the auditorium through an emergency exit about 30 minutes into the film, set off a smoke bomb, and began shooting. Holmes stalked the aisles of the theater, shooting people at random, as panicked movie-watchers in the packed auditorium tried to escape, witnesses said.
