FILE - This Wednesday, Nov. 28, 2012 file photo shows a sweater with a Disney tag found among the equipment in a burned out garment factory on the outskirts of Dhaha, Bangladesh. A week after a blaze at the factory killed 112 workers, a glaring question remains unanswered: How, exactly, did brands worth fortunes end up in such a place?
