It is possible for a charge like this to be dropped but it's completely within the state attorney's discretion. Even though that attorney will speak with the victim (mom) to see what she "wants" it is still up to the state whether or not to press ahead with the charges. It would be smart to hire an attorney who could talk to the state attorney before a filing decision is made.
