None of the "facts" about the timeline have been confirmed by anyone in the know, save for a few things established by LE at the time of Mary Winkler's arrest.
The very last word I saw from Orange Beach police in AL or perhaps Selmer PD who transported her back to TN was that the "condo" (which is not the motel room where she was about to stay on Thursday night) was rented after the murder took place.
There is a ton of misinfo floating around and it's taking quite a bit to track things down to their origins.
I think that it is called gossip!!!!!!!
