This Pulitzer Prize winning photograph was part of the former Rocky Mountain News special section titled "Final Salute".
The article is about the group of Marines stationed at Buckley AFB (near Denver) that makes the calls on the families of fallen soldiers. Jim Sheeler (writer) and Todd Heisler (photographer) both won Pulitzers for this. Sheeler followed up with a book.
Alas, the Rocky is no more.
