Just wanted to point out that the hut Kirkland was killed in was owned by 'Michael Kirkland' - Bob Kirkland said his brother was 'taken' when he was a child. If that was the case then why would the house be under Michaels name. It wouldn't have hid the fact Bob was using it if it has his surname. And I doubt it would be used as some form of shrine.

I'm not saying Michael Kirkland is RJ, however it does seem like a message that he is at least alive, and was in contact with Bob to allow him to use it for his torturings.
