If, at age 5, you had been wrested from your usual environment and subjected to an ordeal comparable to hers, I'm sure that, after only a few months, you would have forgotten most of those "factual memories." At that age, the brain is still very plastic. Without occasionally "refreshing," such dry factual information will be quickly sublimated and, eventually, deleted.
Not saying that I believe her story - on the contrary: She ought to have absolutely no memory of the circumstances of her initial abduction.
Regards,
I have very clear memories of several things that happened, and a few nightmares, when I was three years old.
