his neighbor was murdered and they wanted to question mcafee since he was his neighbor, but because mcafee is a paranoid-as-fuck freakshow he fled

maybe he did kill that guy or maybe he was indirectly involved, but i find it just as likely that he had nothing to do with it and just doesn't want to talk to the cops. either way afaik there's no evidence he killed him unless just living nearby is evidence enough to make an accusation like that
