If the money was wired, its gone. :( She can contact the police, but the people that end up with the money are quick and slick... her chances of recovery are slim to none. Sorry to not have more hope for you, however, I work in the banking industry and have seen this situation before.
If it was just wired yesterday or today, they can ask the bank to do a retrival, that it was sent based on fraudulent terms... if it is still wherever it ended up, she may get it back.
