For one it depends on wether she's still profitting from her crimes. If she's done good with what she illegally obtained and nothing remains - talking in money terms - then she still has to make it up to the people in some way, from whom she stole. That now depends on her financial status, it should be adequate.
There is a reason though, that certain crimes are time-barred (or whatever the correct term is). People do change over long periods of time. So for the following, she will not have to face a sentence: Real Estate scam and fraud, Distribution of illegal substances, Adultery and Marriage Fraud, except of course as said in the beginning, if she is still profitting from it financially.
Second of course, for the more heinous crimes (human traficking, rape, child abuse, serial killing), she'll have to serve some sentence, for the lives she ruined. A nice penalty would be to be required to help people in similar situations now (victims of the same crimes).
And last but not list, what's so bad about a rapper?
