It's been a while since I thought about Kronk so I went back to read some of the threads. MR's connections was/is one of the big mysteries of this case to me for several reasons. There was LP's "daisy chain" theory - which seemed to be involving a discussion between ICA and JB, overheard by MR's girlfriend who worked at the jail, told to MR, who tried with varying degrees of urgency to get police to look. There were the mysterious pavers, which the PI's searched for and found, although they ended up being the wrong pavers. The LP theory being that the PIs were tipped off that they could find Caylee in that area, near the pavers in a bag... and maybe MR was tipped with the same, incomplete and vague information. This makes a lot of sense to me.
I have long been confused by the various descriptions of the "bag" MR saw, which he described at various times as "gray", "metallic silver", "vinyl" and "like a pool cover". Of course we now know it was a black garbage bag and a laundry bag which was neither gray nor silver nor vinyl. If he had a vague tip like "I heard ICA tell JB the body is in that area near pavers in a bag" he could have looked, seen a bag, and reported it. Oops, wrong bag. Ok, looks again, another bag, calls it in, still not the right bag. At some point tells his son he knows where the body is and he is going to report it and be famous. Son encourages him to go ahead and do it, I would assume. So the third time he goes all the way into the trees and looks specifically for bones because there is no point in continuing to report the wrong bag. Finds it, reports it, forgets to read the small print

(what weird terminology, JB) and is cleared by police almost immediately.
I don't know. I have thought all along he had information given to him somehow. JB's theory that MR moved the body is ludicrous though and doesn't even make any sense with the DT theory. I need to listen that part again. I think the
mystery location MR found it is exactly where it was when police arrived. But I think he reported completely different bags the first two times because his information was too vague.
And I think the change in CA's demeanor around 11/15 when her PIs were doing their searches was when she learned the truth... I don't think she would have been so changed by a psychic tip but she would have been by a tip passed to her by ICA or her DT. And so she sends the PIs out to follow the same credible yet vague tip that MR got.
FWIW I still think MR is the hero who found Caylee. I just don't think he was simply lucky.
