At the risk of stating the obvious, Sherry looks QUITE young. When looking at Jane Doe's, I think I'd look from like 12 years old and up.
I have been looking basically in the adolescent to young adult but only one has really caught my attention. The problem is that the age is off a couple years, probably explained by her youthful look, but also the body wasn't discovered until 2006. It's on my consideration list.
