The murder trial for James Holmes — the former graduate student accused in the Aurora, Colo. movie theater massacre in 2012 — has been pushed back to October. A judge set a new start date of Oct. 14 for the trial, initially slated to start this month — but he also said that it could get delayed again, since Holmes' lawyers plan to challenge a recent court order mandating a new mental evaluation. Holmes, 26, faces multiple counts of first-degree murder and attempted murder for the July 2012 shooting massacre that left 12 people dead and dozens more wounded. He has pleaded not guilty by reason of insanity; his lawyers concede he was the lone shooter in the rampage but argue he was in the middle of a psychotic episode during it. Prosecutors are seeking the death penalty for him.
