 The man the FBI has identified as the shooter was a 20-year-old from Pennsylvania. He was a nursing home worker, and the FBI says he acted alone. So far, there's no indication of a motive. The suspect is identified as Thomas Matthew Crooks. He was shot and killed by the Secret Service on the rooftop of a building about 150 yards from the stage where Trump was speaking at a rally in Butler. Trump was wounded in the right ear. Three attendees were also shot, one fatally.
