they still got no clear motive whatsoever is why
Yeah, the late of motive and lack of clear victim "type" has made it less of a narrative story than when kids die or when there's a specific hate/ideology involved.
From what I can tell, they're still looking at an entire complex of factors.
* Former postal worker
* Possible mental illness
* Depressed, drank a lot, on anti-anxiety meds
* Gun nut to some degree
* Possible health issues
* Possibly lost a lot of money recently
* Had beef with the casino industry
* Atheist with no clear hope in life
Could just be a case where an ambiguous mix off all that shyt put him over the edge.
