Comperatore, a devout Christian who adored his family and two Dobermans, died while shielding his wife and daughters from bullets fired by would-be assassin Thomas Matthew Crooks, 20, who had been perched atop the rooftop of a building adjacent to the rally stage last July 13.

Corey Comperatore's family is calling out the U.S. Secret Service, saying after a year, no one's been held accountable for his death.
