Firefighters tried to hold back a wildfire from consuming thousands of homes and an essential communications center in Los Angeles County as they mourned two of their own who were killed when their vehicle was overrun by fast-moving flames and rolled down a mountain side. About 12,000 homes, as well as crucial communications and astronomy centers atop Mount Wilson, were threatened by the fire. On the blaze's northwestern front, two firefighters were killed Sunday on Mount Gleason near the city of Acton.
