Thomas Matthew Crooks, 20, was shot and killed by a Secret Service counter-sniper team after firing eight bullets in Trump’s direction from a rooftop outside the rally’s security perimeter.
The killer was in a building police described as a “secondary ring,” which was patrolled not by the Secret Service but by local and state authorities.
Trump, who was addressing supporters on stage, suffered an ear injury before he fell and Secret Service agents pulled him from the stage.
In another video, a Butler County police officer can be seen being lifted by a colleague onto a rooftop where Crooks can be found.
