On Christmas Eve, 2008, Bruce Jeffery Pardo knocked on the door of his former in-laws’ home while dressed in a Santa suit and holding a gift-wrapped package. When an eight-year-old girl answered the door, Pardo blasted her with a semiautomatic handgun. Then, the unhinged Santa entered the Covina, Los Angeles home and began indiscriminately firing through the crowd of festive partygoers.
