If it was a disgruntled employee then he would have been IDed by now. There are only about 50 people working for the paper and usually those kind of guys are shooting someone they know. My guess is he is just nuts. The right age for schizophrenia. Politics are probably an incoherent mishmash of delusional fantasies if he has any at all. But we will see. I could be wrong.
Yeah you called it
He was awalking psych case stewing over news reporting about his behavior in a stalking conviction
Tried to sue the newspaper for defamation and lost
