Today marks the start of closed-door hearings in the Aurora theater shooting case, during which the lawyers are expected to discuss suspect James Holmes's mental health in detail. Holmes has pleaded not guilty by reason of insanity to killing twelve people and injuring seventy others in July 2012. As part of his plea, he underwent a sanity evaluation at the state mental health hospital. Prosecutors say the results contain "numerous deficiencies." The purpose of the hearings, slated for four days, is to determine whether Holmes will be ordered to undergo a second evaluation.
