What fraud did she commit? The only actual criminal act she's committed, maybe, is filing a false police report in Albuquerque when she claimed she was kidnapped for a few hours. And that's only a misdemeanor, one for which they've decided not to press charges.
I think this woman is a snotty bitch with narcissistic tendencies, who has had so much money that she's never had to face real life before (EIGHT wedding showers?!?), but it simply is not illegal to walk away without telling anyone. We have freedom of movement.
The American Dream.
