Suspected Aurora mass shooting suspect James Holmes missed a court appearance Tuesday, after banging his head against his jail cell wall in a "half-hearted" suicide attempt, reports CBS4 Denver.
Sources told KOAA that Holmes stood on his bed and fell backwards, apparently trying to crack his head. He followed that by running headfirst into his jail cell wall and on a third try to hurt himself, hit his head against the wall.
Holmes is accused of shooting 70 people after opening fire at a midnight screening of "The Dark Knight Returns" on July 20. Twelve people died in the attack.
