Alison Malachowski and former Marine Sgt. Danny Gonzalez hold each other at the grave marker of U.S. Marine Corps Staff Sgt. James Malachowski - Alison's son and Gonzalez's best friend and fellow Marine - in Section 60 of Arlington National Cemetery, July 22, 2015. The two have remained close since James was killed by an improvised explosive device while on his fourth combat deployment in Afghanistan in 2011. Staff Sgt. Malachowski - who was by all accounts a superior Marine on the fast track to the upper-echelons of military service - was with the 2nd Battalion of the 8th Marines when he was killed on March 20, 2011, while his unit was raising the Afghanistan national flag over a small compound near Patrol Base Dakota in Marjah Province.
