This is all extremely worrisome to me. Many here who thought they needed "more" to favor RA's guilt indicated that if he had revealed information in his "confessions" that only the killer would know, that would go a long way, but if he didn't, it wouldn't be helpful. If the information revealed today is true (and I've no reason not to think so), the "confessions" go sadly in entirely the other direction.
When I say "worrisome," I mean that, given what we know from public filings, I don't see how the state will get a guilty verdict here. I hope that there is more to come, as it would be truly tragic if this trial doesn't bring closure.
And not that it's worth much, but if I were guessing (and NOT "beyond a reasonable doubt"), I think RA was BG but didn't act alone.
