On what grounds?

> The victim was later interviewed at a Children’s Advocacy Center, where she alleged that she had talked to Johnson at Sheetz on occasion and that he had asked her age. She remembered him saying he was either 20 or 21. The victim’s sister had previously told Johnson to leave the victim alone and told him how old her sister was.

Unless she helped cover it up I don’t think she could even be charged with accessory after the fact. What I interpreted was she was only aware of the advances and (and please someone correct me if I’m wrong!!) not at the scene when this took place which is not enough to charge her.
