About this version: NPR first obtained a copy of the JAGMAN investigation from Elena Zurheide, whose husband Robert was killed in the explosion on April 12, 2004. She didn't receive it until 2007 — when the Marine Corps was dragged before Congress to discuss instances of friendly fire.
About this version: David Costello also received a copy of the JAGMAN in 2007, when Marine officials promised to share it with the men who were seriously wounded in the blast. His version includes the grid coordinates that were redacted from the Zurheide copy, but it doesn't include many of the details about how and why the officers involved were not punished.
