I say one thing missing, or two things don't add up for me with MR.
While I think he's very good for this by all accounts, last person to see him,
unseemly history, not too close with his kids, etc. I also think how could MR
pull off what seems to be the perfect crime? How could he with his drinking and
temper pull this off leaving no trace, well enough to leave a local LE and entire WS site

and the FBI stumped for 6 weeks? Of all the things he strikes me as, cunning, crafty, slick, sly and undetectable are NOT any of them. Maybe AZG can weigh in if she likes. I just agree very much that MR would fit perfectly into this box of what the perp might look like in this case and yet I don't see how a raging drinking wild man could do it and not have left evidence of it. To have him the perp and leave nothing behind would actually make him NONE of the things we think / know/ think we know him to be. Right? It seems the kind of person who gets away with this forever is the quiet, passive, never raises a ruckus type of person, neighbors thought he's an angel and real sweet and helpful , thoughtful, educated, etc. The list goes on but I think you get the drift.
So to paraphrase, after my rambling, if MR is guilty of Dylan's disappearance he is NOTHING that we think he is . He's a different person altogether than what we've been looking at .
Which is it ?
