Anon is researching mushrooms to help with PTSD.
Terence McKenna found some mushrooms in Amazon and gave some to a colleague after smuggling them back to the US.

Steven H. Pollack
Name leaped out at anon; sure enough, that was the Vegas shooter who was recently back in the news; only difference is the spelling, name sounds the same but it's Stephen.
