According to the National Post
, Denver police have searched the suspect's apartment and found it to be 'booby trapped' with elaborate explosives and flammable materials. Holmes was arrested after a deadly shooting spree at the premiere of the latest Batman movie (The Dark Knight Rises) in the suburb of Aurora, Colorado.
The suspect himself tipped off police that there were "possible explosives in his residence," said police chief Dan Oates. The chief also said disarming the devices could take hours or days. Thus, in addition to killing 12 and injuring dozens more at the movie premiere, Holmes may also have put an apartment building of residents at risk.
Holmes is the sole suspect in the shootings, and there appear to be no ties to larger terrorism organizations. Up until recently, he was a PhD student in neuroscience at University of Colorado medical school.
"Wearing a gas mask, Holmes allegedly set off an unknown gas and fired into a crowded movie theatre at a midnight opening of the new Batman movie in Aurora, Colorado, killing at least 12 people and injuring at least 50 others," said the report from National Post.
