A torn and muddied American flag flies as employees of a boiler company search through the wreckage of their office on the east side of Joplin, Mo., Tuesday, May 24, 2011. At least 116 people were killed and hundreds more injured when a tornado cut a destructive path through Joplin on Sunday evening. The workers said the flag was not theirs, but that they had found it in the building's debris, apparently carried there from somewhere else. (AP Photo/Mark Schiefelbein)
