 Pennsylvania Governor Josh Shapiro says Cory Comperatore was killed at the rally, his family posting tributes online. Shapiro says the retired firefighter died protecting his family. He wouldn't want to be thought of as a hero, but that's definitely how he should be remembered. The FBI says Crooks was not on their radar and no motive has been found just yet. Right now investigators are looking at his cell phone to see if he was consuming any misinformation. Perry Russom, ABC News, Milwaukee.
