A massive fire burned homes as it roared through a mostly residential neighborhood in the hills south of San Francisco following a loud explosion Thursday evening that shot a fireball more than 1,000 feet into the air and sent frightened residents fleeing for safety, witnesses said. San Bruno Fire Chief Dennis Haag confirmed that at least one person was killed in the blaze. He said it would take fire crews until at least Friday afternoon to do a full search for more victims of the fire.
