James Holmes was wide-eyed and unshaven as he sat staring down.
He appeared Monday after being accused of the shooting rampage at a Colorado movie theater that killed 12 people and injured 58 others.
Authorities say the 24-year-old former graduate student is refusing to cooperate and it could take months to learn what prompted the horrific attack on moviegoers at a midnight screening of the latest Batman film.
Investigators say they found a Batman mask inside Holmes' booby-trapped apartment after the attack.
Holmes has been held in solitary confinement since Friday. Prosecutors say they may consider the death penalty but will make that decision after consulting with victim's families.
