A Denver police bomb squad vehicle is pictured outside an apartment building in Aurora Colorado, July 20, 2012. A masked gunman killed 12 people at a midnight premiere of the new Batman movie in a suburb of Denver early on Friday, sparking pandemonium when he hurled a gas canister into the auditorium and opened fire on moviegoers. Police also searched the suspect's apartment building, breaking into a second-floor window after officers had been lifted in a crane, looking for explosives after the suspect made statements about explosives in his home.
