JUST IN: A guy outside the rally saw the shooter crawling on a roof and attempted to warn police and the Secret Service.

"We noticed a guy bear crawling on the roof with a rifle."

"I'm standing there pointing at him for two to three minutes, and the Secret Service is looking at us."

"Next thing you know, five shots rang out."

"Secret Service blew his head off."

"They crawled up on the roof and made sure he was dead."
