They've changed the age to 50 t0 70 years old.
I know I'm probably wrong but what about Franklin Palmer from Washoe County?
https://www.findthemissing.org/en/cases/10131/0/ I know it's a long shot, since the heights don't match up and I'm not sure how quicky a decomposed body can become a skeleton in a matter of weeks.
It would help if they had Franklin's dental chart up.
