Sandra Flynn Fisher vaguely reminded me of this UID's reconstructions. It's a huge leap, but wanted to list her here among the other suggestions:
http://doenetwork.org/cases/2832dfky.html.
I say a huge leap because her family would have to not know of/forgotten to report her tattoos (or maybe she got them during a stint traveling with the carnival) and not know of/neglected to report the issue with her foot. She would have somehow lost her glasses, gained 20 pounds, and seemingly have traveled between Maryland, Florida, and Georgia without contacting home. She's also a year or two above the estimated age range.
