This guy is clearly deranged, but 5-10 years ago, he wouldn't have even heard of the whole trans thing, he's from a small PA town outside of Scranton.
He's posted videos of him planning the massacre, it looks like the trans angle is overplayed here, he is somewhat normal gender wise. The crime is totally premeditated.

May his victims rest in peace.
