I only mentioned the age because a forensic anthropologist put her age estimate at between 14.5-16.5 years old. Just to clarify, she was 17 when she went missing, but her birthday is September 29th, so if it is walker county Jane doe, then she would have been newly 18 by Nov 1.
I didn't see any mention of her having a child despite the Namus photo of her with a baby. But I will say this, my mom had my brother when I was a senior in highschool. Everyone thought he was mine and that I hid my pregnancy well. So it could possibly be a sibling.
Disregard obviously if it IS her child as WCJD had no evidence of birth. But everything else looks good. Even the nose and face. Although, I don't see a resemblance to "Kathy" and I'm one of the few that never did.
