[Updated at 12:31 p.m ET] The suspect in Colorado shooting case has been charged 24 counts of first-degree murder.
Holmes was charged twice for each victim who was killed.
There are three different classes of murder charges in the state of Colorado. One set of charges is because Holmes is accused of shooting after deliberation, referring to the planning of the attack. The second set of charges is because he is accused of having an attitude of universal malice, manifesting extreme indifference to the value of human life.
Holmes was also charged with 116 counts of attempted murder, one count that is a sentence enhancer because of violence and one count for possession of explosive devices.
Arapahoe County District Attorney Carol Chambers said last Monday that deciding whether to pursue the death penalty would involve input from victims and their relatives. A capital case would require a finding of either extreme indifference or deliberation.
[Updated at 12:17 p.m ET] James Holmes, the man accused of opening fire this month inside an Aurora, Colorado, movie theater, has been officially charged with a total of 142 counts, including first degree murder in relation to the shooting.
[Posted at 11:30 a.m. ET] The man accused of opening fire this month inside an Aurora, Colorado, movie theater will have his second court appearance Monday, when he is to face formal charges.
James Holmes is suspected of killing 12 people and wounding 58 during a Batman film premiere on July 20. He is also being held in connection with the subsequent discovery of his booby-trapped apartment, which authorities think he rigged before the massacre in the Century Aurora 16 multiplex.
Holmes is to be led Monday morning through an underground tunnel that connects the courthouse to the Arapahoe County Jail, where he has been held in isolation without bail.
At his court appearance, which starts at 11:30 a.m. ET, he is expected to face 12 charges of first-degree murder, charges of attempted first-degree murder and charges related to the booby-trapped apartment.
In his initial court appearance last Monday, the 24-year-old former doctoral candidate - his hair dyed various shades of orange - appeared dazed and did not speak.
Arapahoe County District Attorney Carol Chambers said last Monday that deciding whether to pursue the death penalty would involve input from victims and their relatives. A capital case would require a finding of either extreme indifference or deliberation.
Authorities have remained silent about a possible motive in the case.
