For each victim, Holmes is charged with one count of premeditated murder and one count of murder with extreme indifference to the value of human life.
Last week, Holmes' attorney said his client would plead guilty immediately in exchange for a life-without-parole sentence. But District Attorney George Brachler rejected that offer and told the court he would be seeking the death penalty instead.
"My determination for James Eagan Holmes - justice is death," Brauchler said.
Trial Set for February 2014
Dressed as "The Joker," Holmes set off two tear gas canisters in the Century 16 theater at a midnight premiere of "The Dark Knight Rises" and began shooting moviegoers. Witnesses said he specifically targeted anyone trying to exit.
He killed 12 people and wounded 58 others. He had ammunition to shot more, but his weapon jammed. He surrendered to police in the parking lot outside the theater.
The trial was originally scheduled for August 5, but after it became a death penalty case, a new judge was appointed. Judge Carlos Samour Jr. set the new trial date for Feb. 3, 2014.
