I don't think there's a way to find current owner--the Jockey Club doesn't really track that. No transfers of ownership on record (but that does not mean she's not been sold.) Last live foal on record is the 2006 mare, Dnt's Sonic Babes. Bred by Curtis Sampson in MN, which is probably the best place to try to find the mare--he's also listed as her breeder.
She had a dead foal in 2009. She has not been sold at auction.
