Targeting a crowd of thousands, Paddock killed 83 people and wounded more than 800. Over the course of several days leading up to the shooting, Paddock had covertly amassed an arsenal of high powered weapons in his room. Using bump-stock attachments, he was able fire off more than 1,100 rounds of ammunition during the 10 minute attack. With his hotel suite surrounded by authorities, Paddock died by a self-inflicted gunshot wound to the head. His motive remains unknown. The shooting is the deadliest in U.S. history.
