Yes, of course, she could have been living anywhere, even though she gave an address that may/may not be valid. I'm sure LE knows exactly where she lives and her timeline, the same as I'm sure they know everything else about this case. I believe the point to some of these posts, not yours SS, is, if she came from where she said she lived and there was no trailer there, you gotta wonder if she was living in a tent or the real address is a secret known only to her employers, LE. It would be such a handy sleuthing tool to know where she was coming from to get to Ron's rented MH in 15 or so minutes, or was she there prior to that? See, some of us have suspicious minds and suspicious minds solve more cases than believing everything someone "says". God knows where LE would have been if they'd have believed Casey Anthony.
Carry on, after all this is only my opinion.
