I have 4 matches for
#UP4388 that are not on the exclusions list. I went on the hunt for more after hearing the news about Elaine. I factored in MP's with sandy/blond and brown hair as the Doe may have had blond or very light brown.
Floy Jean Bennet
Benita Gay Chamberlin
Elizabeth Mary Byron
Barbara Annette Mclure
All the usual things match (hair, weight, height, ect.) so they can't be excluded much on any of those to my knowledge.
These are matches I found to be worth posting from CA, WA and OR, the places her killer would have had to be if #UP4389 is Andria Bailey. All of these are from 1978 though, not 1979 so the CA and OR matches are more likely here. None of them seem to have the eye being lower thing but it does say *slightly* in #UP4388's profile.
Let me know who's most likely so I can submit them and make my usual table. I will also make a more detailed post with the side by side pictures.
