A final salute echoed through a Michigan funeral home today for Nicholas John Acker, the Air Force veteran found dead inside a mail-handling machine at a U.S. Postal Service distribution center. The 36-year-old had been building a new life with his fiancée when a routine shift turned into a tragedy. Acker disappeared during his overnight shift Nov. 8 and was later found inside a mail-handling machine at the Detroit Network Distribution Center, a major USPS processing hub in Allen Park, Michigan.
