A gunman in a gas mask hurled a gas canister and opened fire in the sold-out theater during a midnight showing of the new Batman movie Friday, killing 12 people and injuring 59 in one of the deadliest mass shootings in recent U.S. history. The shooter was arrested shortly after the attack, and law enforcement officials identified him as 24-year-old James Holmes. (AP Photo/David Zalubowski) ( Photo)
