I just located this girl's photo (corresponding to a "no-photo" NamUs casefile) and am putting her up as a possible for this case. I wouldn't say that she's a strong possible, but she is a possible nevertheless.

(Note: The photo is her sophomore portrait from the 1975 Dunedin HS yearbook taken around Sep'74, approximately 10 years before her disappearance, and approx 14 years before Jane Doe's death.)
There is a two-inch difference between her listed height and the UID's measured height.
The UID was found in Fort Lauderdale (i.e., the same city from which she disappeared. Their noses look pretty close (both are prominent, bulbous, and narrow). Their jawlines and temple widths are similar. They both have similar forehead height. A person's chin will normally fill-out and broaden from age 15 to 30, and considering that, the chins are close).
And of course, she could have permed her hair.
