I know that in this case, it wouldn't work, but the sorority sisters that egged her on could possibly have been charged with "aiding and abetting", i.e., "party to a crime", which may carry the same penalties as the offender.
I would think that $1200 credit card fraud would be a felony so what would affect her the rest of her life. If your state is an "open records" state, it would be interesting to see if she has been "weak" before.
There was a case in a nearby town where a prominent dentist forged blood work papers to hide the fact that his underage daughter was drunk. Darling Dau will prob get a light sentence (maybe a first offender sentence where she gets prob and the record is sealed for employment/licensing purposes) whereas darling dad may end up with a felony.
Hope your offender has enough trust fund to weather a bad rep and/or criminal history that future employers will find out about
