Intriguing, indeed. Please post updates if you can! If it turns out that Madelyn is not Beth Doe, she might just be another Doe instead.
As for the isotopes, I wouldn't rely solely on them; they have turned out to be quite inaccurate for many UIDs lately.
As for Madelyn: I know way too little about her and her case, but I came to think of
DeVernon LeGrand and his "church" in Brooklyn, NYC, nevertheless. AFAIK, several of his (and his sons') alleged victims have yet to be found.
First that i have heard of this perp, wondering about potential other victims of his who have yet to be discovered or identified.
The rumoured dismemberment of some of his followers certainly makes one wonder about Beth Doe, although one might expect that her unborn baby would not be white- but then who knows?
There is mention of a girl who was olive-skinned and could pass as Italian, apparently bringing in more cash for that reason, might Beth Doe have been used for the same reason?
speculation, imo. rbbm.

"Church members Gladys Stewart, 16, and her sister Yvonne, 18, had testified for the prosecution in LeGrand's bribery trial, but they were missing when the D.A. sought to use their testimony in the later rape case.
Informants said the girls were dead, dismembered in the Brooklyn "church," with their remains transported to the Catskills for disposal. State police dug up the ranch in mid-December 1975, but they came away empty-handed.
Three months later, on March 6, assorted bones and bits of cartilage were found in Briscoe Lake, and Brooklyn raiding parties turned up human bloodstains in the Crown Heights townhouse."
"Every morning, LeGrand's phony nuns would pile into his Cadillac and he would drop them off at locations across the city.
One fake sister, Vivian Roye, "was olive-skinned and passed as Italian -- she did very well on Mulberry Street," recalled former Brooklyn prosecutor Harold Rosenbaum. "
