"Colorado theater shooting suspect was neuroscience Ph.D student."

At the University of Colorado-Denver.

[James] Holmes is suspected of walking into an Aurora theater's midnight showing of "Dark Knight Rises" wearing a gas mask and bullet proof vest and shooting at least 54 people. Twelve are reported dead.

There's a photo of the 24-year-old man at the link. He looks ordinary. Smirking... but it's the kind of smirk I associate with the character Jim on "The Office."

ADDED: Breitbart reports:

According to New York Police Commissioner Ray Kelly, James Holmes, 24, the alleged perpetrator of the mass murder at the Aurora, Colorado theater showing of The Dark Knight Rises, claimed he was “The Joker” during the shooting. “We have some information, most of it is public,” said Kelly. “It clearly looks like a deranged individual. He had his hair painted red, he said he was ‘The Joker,’ obviously the ‘enemy’ of Batman.”...

Health Ledger’s portrayal of Batman arch-nemesis The Joker in the last installment of the Batman saga, The Dark Knight, won him a posthumous Oscar. The Joker was focused in that film on destroying Gotham City through chaos and mass murder; he also rigged buildings with booby traps in order to achieve that end.
