I have searched the Doe Network Database for matches of people reported missing in 1990 &1991, Ages 19 to 40. There are some so-so matches but none that jumped out at me.
The sketch is of a beautiful young woman. Problem is the information provided isn't complete. I've tried searching for more information about this Jane Doe and could only find the Doe Network page.
From the beginning I thought the sketch looked a lot like Tammy Lynn Leppert. I've posted this is Tammy Lynn's thread, along with my strong reservations that it isn't her. You can find my reasonings here
I haven't given up searching for this Jane Doe yet, and will post any possible matches I might find.
