Emergency crews searched the broken remnants of an Oklahoma City suburb Tuesday for survivors of a massive tornado that flattened homes and demolished an elementary school. At least 24 people were killed, including at least nine children, and those numbers were expected to climb. As the sun rose over the shattered community of Moore, the state medical examiner's office cut the estimated death toll by more than half but warned that the number was likely to climb again. Spokeswoman Amy Elliott said she believes some victims were counted twice in the early chaos of the storm that struck Monday afternoon. Downed communication lines and problems sharing information with officers exacerbated the problem, she said.
