Ok just a little bit of insight into the matter.
This girl is very smart, has a sense for comedy that you don't see in most females. Is EXTREMELY good looking and also very cunning. She is the type of woman who can get what she wants just by her appearance. Beyond all that she is sharp as a tack.
It was all about retribution>getting back at this member she thought she cared about who had shunned her. Not really shunned her... but...kinda left the site for reasons that are... inexplainable. Maybe he led her to believe that he was somebody that he was not. Something like that.
Her specialty is surveillance software. For tracking someone's online activity, tracking their cell phone, those things. I wouldn't put it beyond her to to be able to obtain the use of a spy satellite.
Well, somewhere along the way she contacted The Letterman show where she emailed photos of herself explaining her profession and letting them in on this stuff she had to tell. The staff more than likely took it to Letterman just for her pictures alone. That's where the romance started along with the material for the show.
Now this is just skeptisism but this is what I suspect happened. Letterman got her into the country, probably on a working visa or just by being able to because he is David Letterman. I'm thinking sometime late 2008 where he began seeing her after the shows taping at night and staying with her and not going home. Remember this is just my theory. Regina Lasko, now Dave's wife I think was suspecting that he was up to something and she confronted him I theorize. It probably went down like "where have you been the last couple of nights and those couple of nights the week before?" Not wanting a scandal upon him and the destruction of a child, a home and 23 years of a relationship together, he decided to marry.
I may have missed it completely or I may have hit the nail on the head, I don't know. But, i do know there were communications between the two.
