I found this today in the local (TX) news, and looked up this article.

It doesn't give a lot of information, and I'm not sure if he was a thru-hiker or not, but just wanted to post the info to let people know.
He was hiking on the hunt trail, when a large rock became dislodged and struck him, injuring his shoulder and ankle to a degree that he could not hike out.
