I will say that no matter what I think about what happened, I have no way of knowing what is the truth of the matter.
The sad thing about it is that the only person (or persons) who actually knows (or know) what happened is the
real killer (or killers), and he (or they) is (or are) not talking.
This thought begs the question, if the WMFree were guilty, what advantage would there be to them to
not talk? If they "own up" to the crime, double jeopardy would prevent them from being tried again. I guess the only thing that would hold them back would be fear of reprisals, but that possibility still exists now because so many people feel that they are guilty. IMO, the only reason for them to maintain their innocence at this point is that they are, in fact, innocent.
OTOH, if the WMFree were not guilty, the
real killer must be in agony now. He has stayed free (and not even suspected by the WMPD) for over eighteen years. All of a sudden, the men serving time for his crime are out - and still maintaining their innocence and working hard to prove their innocence, with the help of some very deep pockets. Either the
real killer has a "special" relationship with LE in Arkansas (that allows him to feel safe) or he is shaking in his shoes about the possibility that the defense team will find the one incriminating piece of evidence they need to exonerate the WMFree. (My guess is that they have found it already and will reveal it in due time - when the case against the
real killer is airtight.) Either way, I don't think he sleeps very well.
