California crews try to reach smoldering homes after blast
SAN BRUNO, Calif. -- Investigators searched the smoldering rubble of a quiet, middle-class neighborhood tucked into the hills overlooking San Francisco on Friday, looking for answers to why a gas line ruptured and fed a giant fireball that killed at least four people. Firefighters finally contained the fire Friday afternoon, but at least a quarter of the 15 acres of charred homes were still too hot to search. Crews with dogs went house to house and officials said there could be more casualties.
