What do you mean by "immediately"? I took your post at face value but later I heard he'd shifted right over a period of months. But I don't have details.Interestingly, immediately before the attack, social media accounts with his name on them suddenly started posting pro-Trump, far-right, and anti-Vaccine messages totally counter to his previous history. This is in no way suspicious at all.
We also now have a picture of his home, which the neighbors called a Hippie Collective. He's a registered voter with the Green party.
