What happened to her?

Interesting question. She was very attractive and and since she worked regularly until 2011 I speculate she was easily to work with.

Possibly retired.

"Susan Smith" and "Kerry St John" didn't do enough to get her more publicity..

Besides, Arija Bareikis is a poor man's AckbarsRevenge.

I think Susan/Kerry's campaign embarrassed her and she dropped out of the public eye
