I would love for the father to be the culprit in some way, personally, wishing he sent someone to hide Jessica away somewhere.
That would probably be the best of a bunch of bad outcomes but it wouldn't be a good outcome.
So long ago that I can't remember the woman's name (sorry) I read a book by a woman who was abducted by her father in a custody dispute with her mother when she was fairly young, 6 or 7 years old. He kept her for 3 or 4 years before they were caught (this was way before the internet... I'm thinking 50s but am not sure).
He wasn't exactly abusive but being suddenly ripped away from her mother and siblings, having her name changed, being on the move so they never settled down and she couldn't go to school, etc, was really confusing and upsetting to her. Particularly since he kept telling her that her mother was forcing them to do this.
When she was finally found, she was 11 or 12 years old, had almost forgotten her birth name and had almost forgotten her other siblings. In any case, they had grown significantly, so were no longer like her few memories of them. The ordeal had changed her mother, too; she was stressed and had a shorter fuse than she did before the abduction (stress will for sure do that to you).
It left the woman feeling like she had no ties anywhere. She was way behind scholastically and back then, the only remedy offered was to put her in classes with kids 4 years younger than she was. Without much help from the school, she managed to make up 2 years of missed school in one year. But that just meant she was promoted into another grade of kids that she didn't know.
As an adult, she had major, massive problems forming attachments to anyone. She found it really hard to get over the feeling that there was no point in making friends let alone romantic attachments because they would all go away in a year or so anyway.
I get that if Jessica were involved in some sort of contracted custody grab that at least she'd be alive and probably not abused horribly. But I think it's one of those "least evil" outcomes.
