I'm repeating a thought that has been mentioned in this forum in the past, but it's been a while since it's been brought up. If for no other reason than to keep people thinking about it -- either as a clue to LEK's birth name or her personality.
In every other case of identity theft that I've heard of, the perpetrator simply assumes the name & as much of the other's history as reasonably possible. But in this case, once LEK began the change over she chose a whole new name for herself. As far as anyone knows, she used the name "Becky Sue Turner" very briefly: once to get her Idaho ID, a second time in a Texas court room to change her name to Lori Erica Kennedy. And maybe a third time when she obtained BST's birth certificate in Bakersfield. If any name for her new identity would work, why didn't she remain BST? AFAIK, no "Howto change your identity" handbook suggests performing this additional step. In other words, she picked that name after some thought & thus for some reason.
What was that reason she picked the name "Lori Erica Kennedy" for herself? Did it have some special significance for her?
There has been some discussion of the significance of this name in older threads. One person noted that it was a common birth name in the 1960s. Another poster suggested her birth name likely began with an "L", & she picked Lori to handle accidents where she began to accidentally sign her birth name, & could recover by writing "Lori". Still another noted that "Erica" was the name of a character of a popular tv soap opera in the late 1980s. And saving the most trivial observation for last, "Kennedy" is a common Irish-American family name, very few of whom are even distantly related to the president.
If we knew more about her, I would eagerly make some intelligent guesses, or even suggest some plausible theories, why she picked this name. But I've tried to be cautious about this case, & except for noting that this name was her intentional choice, & must have some significance to her, I'll leave it to the rest of you to speculate further.
