Nothing to add to PZ's concise summary or Ophelia's first-hand account (and see all the links) ... but just in case you missed it. I think I said at the time of his first fess up, when much love and forgiveness was being offered, that I still didn't trust him. But that's history.
Edit: Hmmm, well I said this, which is not quite the same thing, or, rather, it's more specific. All the same ... Oh, and I think at that point he was (falsely) denying that he was a graduate student and claiming that that had been a lie to cover his tracks, so there actually were big revelations to come. But really, this guy's twists and turns make my head hurt.
