I had forgotten about this case but remember that her being a Physician is the number 1 reason I don't think she voluntarily disappeared. There's no way she could move, change her name and start a new life because she could never get credentialed again. I suppose she could not be working as a physician but despite everything else she sounds like she was very dedicated to her job. I think she went missing the night of September 10th/ early morning of the 11th, maybe kidnapped and murdered walking home but the timing of 9/11 didn't allow for a real investigation. Or maybe being the dedicated physician she was she did respond to the scene on her way home and died there but I don't think so.
