From research I've done, that area was blighted at that time, with abandoned buildings. Somewhere up thread, locals have posted that the area was kind of a dividing line between a "good" area & a "not so good" area. I find this interesting:
"DNA testing confirmed the profile St. Louis experts already had, but the mineral tests, or stable isotope analysis, revealed the child probably spent most of, if not all of, her life in one of 10 southeastern states: Florida, Georgia, Alabama, Mississippi, Louisiana, Arkansas, Texas, Tennessee and the Carolinas."

I've thought for a long time that somehow that little girl made it to STL shortly before her death. LE was pretty thorough investigating in and around the STL area. My theory is that this little girl' parent(s) died and she was awarded to her next of kin (bio dad, older brother, uncle, etc) and that person is the perp. Nobody from her home area would know she was missing and nobody in STL would realize she was there to miss her.
Thoughts?
