Secretary of the Air Force Michael B. Donley issued a letter to all Airmen Nov. 8.

In it, he wrote, "The mission at the Air Force Mortuary Affairs Operation (AFMAO) is to provide dignity, honor and respect to the fallen and care, service and support to their families. The professionals whose privilege it is to perform this solemn duty take great pride in that responsibility to care for America's fallen.

"However, due to specific concerns raised by AFMAO professionals regarding policies, processes, and procedures, the Air Force conducted an investigation that focused on allegations of mismanagement and accountability," he continued. "The Air Force has contacted the four families directly affected by the investigation and discussed these matters with them personally. If you were not contacted already, you are not one of the impacted families."
