Roberto Martinez hops over the police tape as he carries his belongings from his home near the apartment of alleged gunman James Holmes Friday, July 20, 2012 in Aurora, Colo. Authorities report that 12 died and more than three dozen people were shot during an assault at the theatre during a midnight premiere of "The Dark Knight." Colorado firefighters are monitoring the Aurora apartment building for gases in an effort to determine what chemicals they say 24-year-old James Holmes might have used to trap the place _ in case the materials go off.
