From Green Eagle:
On October 1 of last year, as most people will sadly remember, a man in Las Vegas barricaded himself in a hotel room and began shooting at a concert below his windows, killing 51 people and injuring over 800. The man seemed to be a prosperous middle class man with no known connection to terror groups, and his motives for this monstrous act seemed doomed to remain forever a mystery.
Now, however, it seems that the mystery has been dispelled.
