Greetings,
I am new here, I too became curious about this case after reading the ST article. I was born in the mid 60's in San Francisco, and then moved to the Seattle area as a teen. I believe, like many others here, that LEK was born in the same era.
What intrigued me was the way that Jane Doe created her first identity of BST. I
say this because my own father did the same thing for something as "innocuous" as hiding from the department of support enforcement. I was a small girl, mid 70's, and my dad had some medical records sitting on the table and those records had someone else's name and birthdate on them. I asked him why that was, and he said he had to change his name because my mom was after him. Essentially, he was hiding in plain sight. My dad was a con man that was in and out of prison.
So when I was a teen I asked my dad how he managed to change his name all those years earlier. And he simply told me the same story we find here with BST. He told me that he searched the obituary pages of local newspapers for people who died young and were from a different state, send away for their birth certificate and bingo he became a new person. He was then able to apply for a new SSN etc.
The reason why I bring this up is because so many people have suggested that maybe LEK had used an identity broker. I don't believe that would have been vital to her changing her identity. Here I am, about the same age as LEK, and I had this information as a teen. My dad was part of the criminal element and he had access to this info without paying someone to do it, I just happened to observe a name change and then ask questions later. I had this information long before my 18th birthday. Another connection that I find interesting is that my dad also frequented strip joints in California during this same time period. So my guess is that our Jane Doe is/was part of the criminal element of the day.
Thanks for letting me get these thoughts down. I've also had several other thoughts and will post later.
Thanks, Globones
