James Holmes‘ attorneys told a Colorado judge this morning during his arraignment hearing that they needed more time to respond to charges that their client killed 12 people and wounded 70 others in a Cinemark movie theater rampage last July 20 in Aurora, CO during a midnight screening of The Dark Knight Rises. But Arapahoe County Court Judge William Sylvester entered the plea for him, setting the stage for an August 5 trial. Holmes is charged will 166 counts of murder, attempted murder and other crimes. The plea still leaves open the possibility Holmes could enter an insanity plea, The Denver Post reports. The paper said prosecutors will announce April 1 if they will seek the death penalty.
