I wonder...was Lopez an Iraq war veteran, who was being evaluated for posttraumatic stress disorder but had not been diagnosed?
...something in that write-up leads me to believe so...can’t quite put my finger on what it is, though...
I read that he was in a special brigade at Ft. Hood for “transitioning” soldiers either into civilian life, or back into active service. That sounded to me like it was a special unit for those with PTSD or similar issues.
