Relatives, friends and thousands of uniformed officers gathered for the funeral of 51-year-old Los Angeles police motorcycle Officer Chris Cortijo, hailing him as a guardian angel who watched over Southland motorists for more than two decades. Cortijo, a 26-year-veteran and former Marine, was struck April 5 by an SUV driven by an allegedly drug-impaired driver while stopped at a red light at Lankershim Boulevard and Saticoy Street in Sun Valley. He died four days later.
