Sara Koenig, Was Anyone Killed Looking for Bowe Bergdahl? Some Hard Evidence at Long Last, 6 October 2016.
After nearly a year of waiting, [Serial has] finally received the Army’s internal investigations into the 2009 deaths of six soldiers from Bowe Bergdahl’s unit: MW, CB, KC, MM, DA and MM.
None of these investigations report that any of these men was on a mission to look for Bergdahl. Neither Bergdahl’s name, nor the term DUSTWUN (shorthand for a missing soldier), appears in any of the documents.
