For convenience I proposed the acronym "FLEK", for Fake Lori Erica Kennedy. It turned out that she had used the identity of a deceased child to go to court and change her name, so it was more a manufactured identity than a stolen one. But the name stuck, so FLEK she is until her real name is found.
(Long time lurker here)
The acronym FLEK has never sat particularly well with me. Lori Erica Kennedy was a real, legal name. The "fake" prefix doesn't accomplish anything, simply because Lori Erica Kennedy was in fact the original Lori Erica Kennedy.
Becky Sue Turner was indeed a stolen identity, and FBST would be appropriate (since there was once a real Becky Sue Turner) but our mystery woman moved on to Lori Erica Kennedy, and that's a perfectly legitimate way to identify her.
"Jane Doe" is also inappropriate, since LEK in fact had a name, just not her birth name. She was Lori Erica Kennedy. It's the only name (that we know) that was truly hers.
I'm going to go out on a very presumptuous limb here (being a long time lurker and all) and suggest that FLEK be retired. It just doesn't make any logical sense as a descriptor for our mystery woman.
