      |One person was killed and six others were injured when the brakes on their van apparently gave out on a mountain road northeast of Sacramento, authorities said. Emergency officials received a 911 call from a passenger inside the Chevy Astro van shortly before the vehicle careened down a hill, and burst into flames.
