Age of consent is 17, so their threats, insofar as they relate to any conduct occurring after the girl's 17th birthday, are indeed empty. However, be careful you do not admit to any sexual congress with the girl when she was younger than 17. They could still go to the DA and tell them you were having sex with her before she reached the age of consent. Then, you could be charged with Sexual Assault of a Child (under 17).
