Update February 3, 2012:  Sgt. Polk's death has still not been reported by the Dept. of Defense, nor has any notice of his death appeared in his family's hometown newspaper. A source has further informed ECM that his name has not been provided for addition to a memorial that honors fallen special services soldiers. Thus at this point, it appears likely that Polk did not die in service overseas. Perhaps he faked his death, or possibly someone else posted misleading information on his Facebook account.
