My sister forged 18 credit card cash advance checks against a card in my name. What will happen to her if I notify the bank that this occurred?

I originally got an 0% apr credit card for her to transfer a high interest rate balance to help her out. It was in my name due to my good credit score. Her credit scored was & still is in the tank. She asked (and I agreed) if the statements could be mailed to her so that she could make the payments with the coupon. Unbeknownst to me, 'teaser' transfer checks also arrived in her mailbox and over the course of 4+ years, she wrote $8K worth forging my signature on each one. She finally admitted it to me this past summer when she realized that she would be late on the minimum payment. I wrote her a letter telling her how hurtful this was and strongly requested that she figure out a way to pay it off or get it out of my name by December 1st. She cried and wrote apology e-mails but still only is making the minimum required payments. At this rate, it will be 2036 until it is paid off. What options do I have? I do not want to have her sent to prison- just want this out of my name! Please help
