I had seen this story in posts on several blogs, and also via Soldiers Angels. This is a tragedy too terrible to even contemplate, but the gist of it is that a wounded soldier who was recuperating at Brooke Army Medical Center in TX, Spc. John Austin Johnson, lost two of his three children in a car accident that occurred while his wife was driving the family to visit him, and the third child is on life support.
Today is the day they will bury their 2 and 5 year old.
The most up-to-date post I have seen about the story is here (along with a picture that will break your heart.)
