I have some speculation on that. I think if you Google Cherokee Platform Sandals, those were still being worn in 1980. I also think that because she was carrying them and not wearing them, they could have been either A. Not hers, but borrowed or B. A hand me down from an older sibling or friend. Also, 3-4 inch platforms are not comfy, but the wedge or platforms with the solid heel were at least walkable. My step mom had quite a few pairs of them, and she walked 5 miles to work in them. I was given a pair of Candies sandals and was not allowed to wear them, but that was another brand that year. So I think judging by this girl's age, she was either not supposed to be wearing them or someone gave them to her. Depending on how long she had been gone from her parent's home(if she had one), she also could have been preyed upon by a pimp who got them for her. And she might have been in the foster care system, which would explain not being missed. I can't believe anyone, no matter how dysfunctional of a family, would just never pass the word around that "Jane" never came home at one point. Totally moo.
