CNN), Prior to July 4th, Cooper Roberts was almost always active and running. He loved playing sports — including soccer, baseball and soccer — and riding a bicycle, his family said. Authorities apprehended Robert Eugene Crimo III more than eight hours after the shooting and charged him the next day with seven counts of first-degree murder. On July 27, the charges rose to 21 counts of first-degree murder, 48 counts of attempted murder, and 48 counts of aggravated assault.
The shooter used a Smith %26 Wesson M%26P15 semi-automatic rifle with three 30-round magazines. A total of 83 shots were fired. Among the victims were spectators and some of those who were marching in the parade. At least one parade attendee provided medical treatment to the injured, before first responders arrived.
Images taken by Chicago Sun-Times reporter Lynn Sweet, a spectator at the parade, show a Klezmer band participating in a float that continues to play as the shooting began, and many attendees running as they shouted. Attendees captured additional photos of the scene and posted them on social media.
