Her P411 profile has been deactivated for several months now.  She used to contact me when she was coming to town to see if I wanted to get together, but I haven't heard from her for about 7 months.  I presume you've already tried emailing her, with no success.

Take all that together and it looks very much like she has quit the business and probably doesn't WANT to be reached.

I know a friend of hers whom I could ask about Sadie, but don't consider that appropriate when she's apparently chosen to leave the field of play.

*shrug*  My opinion; YOMV.
