I'll add to the conversation, as far as the money is concerned.
U.S. Banking laws and regulations are stringent even back in 2004. If the mother's name was not on the bank account, by whatever means she took the funds out of the account, it was theft. Because it involved banking, it is a Federal felony. It may even be a State crime. In this case, it could be a misdemeanor based on the amount of money involved. Different States, different laws.
The Feds will look at what happened and it will be up to the U.S. Attorney to determine if they want to pursue the case. Because of the facts of the case (and they will know), they may just turn it over to the State (usually along with what the FBI has determined). Whatever happens, the Mother will be put under a microscope.
Having written all of that, Quinn would not be allowed to have an account without one of the parents as a signatory (because he was a minor). Hence, no crime.
