I couldn't "Accuse" the right suspect -- the website wouldn't let me beyond the first three, so I just picked BP but I don't think it's him.  I think poor BP is dead, and furthermore, I don't think it's any of the 7 Suspects [as RJ, that is -- they could have connections, for sure] but suffice to say for now that Jane set that list up for RJ.  Most people seem to want it to be someone on that list, someone we've seen a lot, but I realize now that when Heller says we'll be disappointed, it's because it's not going to be any of the suspects we've been thinking for months.  No -- Red John MUST have a personal link to Patrick somehow.  Patrick Jane's father, Alex Jane, was a red haired con man and we don't know what became of him at all.  We don't know if Alex Jane had other children [or another son]; and we have never heard of PJ's mother or what became of her, either.  There are many literary references, as well as name symbolism used in The Mentalist, and one of them is a "Twins" theme.  I think the possibility that PJ has a brother is there.  Alex Jane seems too old to be RJ, but a brother would be just the right age for RJ.
