and the state of Tennessee can the parent of a statutory rape victim drop the charges

First let me make it clear that this answer in no way creates a lawyer/client relationship.  As statutory rape is a strict liability crime, only the state of Tennessee can drop the charges.  You have left out a lot of information, and my heart goes out to you if you know or are the victim of this heinous crime.
