Definitely see some similarities but there are a couple things that are nagging at me. Rebecca was 21 went she went missing in '79. That would make her 33 in '91. I do feel that our JD may have been older than the 18-21 range, but not that much older! Rebecca is said to have green eyes and JD's were blue. The height is a bit off and although I generally don't put too much stock in that, 5' 11" is pretty unusual for a woman. JMO
I agree with the age thing also
But the thing that pertubs me the most is all the freckles of JD
I cant see them on Rebecca at all
I honestly do not think its her but that is jmo
