James Holmes will get life in prison without the possibility of parole.
The jurors who convicted him of murdering a dozen people and trying to kill 70 more at a midnight movie three years ago could not agree on a death sentence.
The jury of nine women and three men deliberated for less than seven hours over two days.
District Attorney George Brauchler, who had sought to have Holmes executed, said, "I still think death is justice for what that guy did ... but I respect the outcome." He also said the jury did "a hell of a job."
