TUCSON, Ariz. _ He was dashing up the mountain into darkness, chasing a friend armed with a shotgun.
Taylor Hudson yelled for his friend to wait, to stop.
They had rushed together toward danger so many times before on the battlefields of Syria. They had protected each other, made it home safe.
Cactus pierced Hudson's sides as he scrambled up to save his buddy.
Then he heard the gunshots.
