DENVER, COLO. - The man accused in the Colorado movie theater shooting massacre was formally charged in court today.

James Holmes now faces 24 counts of murder and 116 counts of attempted murder. For the murder charges, one count included murder with deliberation, the other murder with extreme indifference. Both counts carry a maximum death penalty upon conviction; the minimum is life without parole.
