Accused gunman James Holmes will stand trial for the 2012 Colorado movie theatre massacre on 14 October (14). The 26-year-old suspect was slapped with a total of 166 crimes, including 24 counts of first-degree murder and 116 of attempted murder, after allegedly opening fire in an Aurora cinema shortly before a midnight screening of The Dark Knight Rises in July, 2012. He is accused of killing 12 people and injuring 70 more in the incident. Holmes has pleaded not guilty by reason of insanity and on Thursday (27Feb14), Arapahoe County District Court Judge Carlos Samour set a date for the trial proceedings to begin. More than 6,000 prospective jurors will be called for duty, one of the largest jury calls in U.S. history, but the screening process could take months, meaning the case may not actually begin until 2015, according to the Denver Post. Holmes could face the death penalty if convicted.
