Police said that after leaving the home, Pardo changed out of the Santa suit and into regular clothes. Raney also spoke about a pipe bomb that exploded in Pardo's rental car Thursday night. He said Pardo had rigged the rental car so that if someone tried to remove the Santa suit, the car would explode. The car was packed with ammunition and black powder, he said. Police said that inside Pardo's home in Montrose, California, they also found five empty boxes for semiautomatic handguns, two high-powered shotguns and "racing fuel," which they believe was used to help set fire to the home.
