Yeah I am leaning toward him being the guy but there are quite a few things that don’t add up. My current theory is that he did it but the cops planted evidence to make sure the charges stick, because most of what they have without the gun, manifesto, and cash is just circumstantial. I also think it’s a bit foolish to have made up your mind one way or another because we don’t have enough information yet. There are things that point to Luigi being the killer and there are things that point to it being a frame job.
