The wheels are in motion for the first of what could be several civil trials of wrongful death and personal injury claims related to the 2012 mass shooting in a suburban Denver movie theater. Members of a six-person jury were chosen Sunday, as well as two alternates, and both sides began delivering opening statements Tuesday. The lawsuit against the owner of the Century 16 Theater multiplex in Aurora alleges Cinemark committed various lapses in security that led to the tragedy in which 12 people were killed.
