Stolen car? They'd be looking for his car with Colo plates, especially as he ran cross country.
I think he indeed had planned to escape. Was shocked to step outside and find the cops already in the parking lot.
Where did he get his knowledge of explosives and weapons
He is 24/25 there is nothing out there about him?
Who are his friends, places he went?
He rigged his apartment as a booby trap with all kinds of explosives. Then put very loud music with a timer. Apparently he was hoping the cops would come when people complained and get messed up and create a distraction so he could do his rampage, presumably kill more people and then escape.
Also, witnesses say that a man in the front (presumably the killer) got up with a cell phone and went out the exit. A short time later a guy (same one?) dressed up in gear came in and tossed a cannister (tear gas?) and then started shooting. Witnesses also have said that there were two cannisters, one in the front and one in the back.
And then theres this:
Police: Colo. shooter James Holmes set up elaborate bomb in apartment as distraction
There appear to be incendiary devices, Aurora Police Chief Dan Oates said. There are chemical elements. There are all kinds of wires.
Investigators now believe that Holmes used a timer to set off loud techno music at the apartment just before midnight. It was meant to spur a noise complaint to police. The ruse theoretically would have drawn them into the apartment building, detonating a firebomb and then drawing all available police and rescue units to the other side of town before the shooting at the theater started. That would have allowed him more time to kill more people and left a much smaller police response to the theater shootings.
This is someone who is engaged in predatory, thought provoking, very well planned out behavior, former FBI profiler Mary Ellen OToole told CBS News.
