A fire that awakened neighbors with a blast as it tore through the home early Sunday has killed six people, officials and area residents said. After the flames were brought under control around 2 a.m., firefighters initially said two people died in the blaze. But authorities said at nightfall, after a day of picking through the charred debris, that four more bodies had been found. (AP Photo/Rick Bowmer)
