Masked gunman shoots 14 dead at Batman screening in Denver Shooting at screening of Batman: The Dark Knight Rises in Aurora, Denver. A masked gunman shot 14 people dead and injured up to 50 at a showing of the new Batman movie The Dark Knight Rises at a cinema in the US city of Denver, police said. Local radio station KOA, citing witnesses, said a figure in a gas mask had opened fire at the showing in a mall in the suburb of Aurora and set off a smoke or teargas bomb. It said initial police estimates were of 30-40 people injured. Dozens of police were at the scene, CNN footage showed. KOA said authorities were evacuating the area while they checked if there was an exploding device there. CNN quoted one witness as saying he saw a "guy slowly making his way up the stairs and firing, picking random people." It said local hospitals were alerted to a "mass casualty incident." Police did not immediately respond to requests for comment, but a spokeswoman for Denver's Swedish Medical Centre said three people had been admitted to that hospital with gunshot wounds and were in extremely critical condition. Another hospital, Denver Health, had received six wounded, one of whom was in critical condition, a spokeswoman said.
