We've got to keep praying for Dylan. I have a strong feeling that LE knows way more about his whereabouts than we are being told, and that they are telling us publicly that he is likely dead to keep his captor from running with him and/or killing him before Shasta can tell them where he might be. Until a body is found, we have to hang onto hope.
Nice theory, good luck with it, but highly doubtful. They've got him in custody, he has violated the conditions of his release by not showing up in court, so he's not getting out of jail any time soon. He will not have a chance.
