You should speak to a victim/ witness advocate at the DA's office. You do not get to pick the DA. This is not you/your daughter vs. the accused, it's the COmmonwealth that would bring the charges against the accused. Therefore, there are no charges for you to "drop", since you aren't the one bringing charges. And based on what you've said, there aren't any charges pending at this time anyways. The District Attorney's Offices in Massachusetts take child molestation more seriously than pretty much all other criminal offenses, so I have confidence that if there was enough evidence they would seek an indictment against the accused. However, if they don't have any evidence to corroborate your daughter's version, or if her version has been inconsistent or shaky, the DA might not have probable cause to charge the accused. I suggest speaking to a civil attorney about possible action on your daughter's behalf. That would be the recourse for "taking action" or filing an action against the accused, BY YOU as the plaintiff (rather than criminal proceedings in which the DA would have to bring the charges). He would likely be able to help guide you through the criminal process as well. I wish you luck.
