NO, i think someoen would have found her before now if she was placed on a tree limb,
i think she was meant to be tangled in the underwater roots and limbs adn the many fish there woudl take care of it and the head is in there I bet
Also think that because it was stated in an article last, that the head may not be able to be found becuase of the many tree roots and bramble under there
I'm not an avid fisherman but have been around, i think the area would be more for fisherman to leave their lines out all night on a jug, whats that called and i thnk for sure i wouldnt' be draggig a line thru that mess, BUT ONLY SURFACE FISHING, fisherman know they'll get tangled in that if it's as bad as LE said about not being able to find the head due to all the tree roots
that being said, no one would have snagged her if she were under there likely
If they wanted them found they'd have left them both at the house or hung them from a tree there to make a statement
i think the moving of her was to waylay the investigation
but the beheading is what the LE is looking at mostly I think
of course they have to follow thru with everything
JMO, i've slept on it and have a whole new view, errr, rather my beginning views and it's getting clearer to me
but I may be WRONG but that's how i feel !!
