Some quick thoughts about the resolved Sharon Marshall case and how they relate to Anna:
1) As Cubby mentioned above, answers are out there. They may not come on our time schedule, but they will come.
2) Suzanne's (Sharon's) family had been looking for her, yet somehow never came across the online or media coverage of "Sharon Marshall". I have found myself discouraged at times that if Anna is out there, why hasn't she seen our efforts and contacted us. Suzanne's case has shown us that it is possible to miss the "elephant in the room" and that we need to redouble our efforts to publicize Anna's case. Online presence, adoption websites, etc need to be exploited to make it so nobody can miss the info.
