OK, I was confused... September 30 is today! So, the answer is now in a Facebook video post from San Diego Police Dept! Cold Case Episode 3. The now-identified woman's name is Nicole Weiss (spelling?), age 20, born and raised in Michigan. They found her with the help of a genetic genealogist, Barbara Rae Venter (sp?).
Thru DNA, they first found a biological half brother, Glen Stevenson, who was "adopted out of Michigan" and searching for family. They learned that Glen's biological father was deceased. However, they were able to identify another child of the same father, Kimberly Beach. When law enforcement interviewed Kimberly, she stated that her family had lost contact with her younger sister since the late 1990s. However, they think she had moved to Los Angeles. Kimberly was a sibling match for this Jane Doe. Thus, she has her identity back. It sounds like Nicole may never have been reported as a missing person, but I am not sure about that part.
