A 24-year-old man named James Holmes has been identified as the singular suspect in the Denver-area movie-theater shooting. Local law enforcement believes Holmes to be the gunman responsible for the deaths of 12 people during a screening of The Dark Knight Rises. Police who searched the suspect’s home said it was “booby-trapped” and that they found “buckets of ammunition” and some type of chemical. At a news conference, the Aurora, Colo., police chief said Holmes spoke of “possible explosives in his residence. We are dealing with a potential threat.” During their search police were trying to disarm any potentially flammable or explosive materials. The police also found four other guns at the theater, after it was evacuated, as well as a gas mask.
