Hi
In the Federal case it doesn't matter, she can't willingy agree and he is done.
In the state cases for kidknapping it will be a debate
I have a problem with how the term "willingly" is being used in this case and another way to describe her actions are "intentionly". And there will be IMO a debate on what is her "will" if she was manipulated and her intent. IMO she intended to go there that day, but the state will have a burden to prove that her "will" was taken from his grooming. The destinction between "will" and "intent" will be important in the state case for kidnapping charges.
In the Federal he is done IMO, plea deal in the works.
