UPDATE

Since Maria did not confirm or deny the username, I have to do my own research.

The account 2122397500 is likely hers or husband's, according to the email address. It was registered on September 9, 2011.

At the time of writing it has a balance of $0.28007 and zero BTC. Currently unclaimed.

Also, Maria's requested amount almost matched the largest balance in Bitcoinica history (and I know the account holder quite closely). I have been sorting by USD balance and BTC balance almost every week since last year and it's impossible that I don't know a user with a substantial amount invested.
