The victim is going to hell in a handbasket all by her own choices.
I don't remember what happened to Tawana Brawley in the end. If nothing else, she either had to change her name or live in perpetual infamy.
Unless the Duke "victim" gets the light and sees religion, her life is going to be one unhappy mess, and probably not a very long one. She does seem to have one advantage over Tawana Brawley--her name isn't becoming a byword.
Mangum will continue to live in the bosom and safety of kindly Durham black folk who won't judge her harshly.
In fact, she may become the heroine who tried so hard to bring justice to blacks by using false claims of rape and other atrocities to go after some rich white boys at Duke who deserved it just because they're rich and white and attending a fine university.
