Coming here from this thread.
I've read everything Maureen has posted; have a bunch of posts I wanted to address but don't have time to do it now.
There were other clubs in NYC if she couldn't get into Studio 54 at 1st.
12 of New York's Most Historic Night Clubs, I'm younger then Judy, used to go to the limelight but it wasn't opened till 83. As was mentioned CBGB's was really popular too where you could get a glimpse of your favorite celebrity which leads me to ask, who were her favorite bands? Was she into Blondie at all?
She could have gone to NYC to model, went to some agencies that sent her to a photographer that most likely hit on her, turned her onto some lines. She also could have worked some fashion shows helping to dress models. That's what they did with some girls looking to model. Let them get a feel for what a fashion show is like and what it means to be a model in one.
From there the photographer tells her he'll introduce her to some people, brings her clubbing; then it can go down hill from there; leading her into being a high priced call girl, especially since she liked to party which would have killed her modeling career. Very hard to be partying, doing coke all night then do the rounds with the agencies.
An ex-BF's sister used to work at a topless bar in Elizabeth NJ as a bar tender. Some how she ended up in NY; working one of those sex phone lines. I was given her number to hook up with her after 10 years, was shocked to hear her answering machine that told the caller to press whatever.
It very well may help. A doe by the name of Grateful Doe was matched to Jason Callahan who's mother donated, interestingly he could not be ruled out against his mother, they ended up getting 3 more samples. Possible they didn't want you due to having your parents but if she doesn't match one of them will one profile be enough for a rule out? That's the question.
If an OD, maybe declared deceased at a hosp and buried in the potters field under one of her names. Happened to my friends sister Linnette. She was being compared to Caledonia NY Jane Doe. We googled all over, she never came up until a year later; someone was comparing her to NJ's Princess Doe, they found her on find a grave under a married name. You never know where she could turn up which leads me to mention Atlantic City. If she was a call girl, she very well could have been down there. A lot of girls are trafficked thru AC.
