 We know the shooter was shot and killed by the Secret Service and reportedly an AR-style rifle was recovered at the scene. The shooter was able to fire multiple shots toward the stage from that structure outside the secure area of the rally. And we have this from the BBC who interviewed a man at the scene. He says he saw the gunman minutes before shots were fired climb up on top of the building just outside of the event. And the next thing he knew, he heard shots ringing out.
