If the parents were in on it they’d be accessories to murder (Corey) and attempted murder (the 2 wounded rally attendees).
Accessories? yup. That’s what I’m saying and that’s just for ownership of one rifle. And they must realize that because it would explain their early call about how their punkass kid was missing? Trying to cover for themselves. The kid had a job but there’s no mention so far if he’d missed work? We do know that he’s visited the fairgrounds in previous days.
