It was in Aurora. It's about an hour or so away from me. Family was texting me making sure I didn't go there..

I am not for Capital Punishment. But time to show this punk *** some medieval torture. What a sick fu*k.

Glad you wern't there.

This suspect sounds nuts. They are saying he was dressed as Bane from the movie hit the theater with tear gas then shot the place up as people tried to flee. They got a hold of the suspects mother who said you got the right guy and his apartment is booby trapped with very high end bombs.
