My math says that OP has 42 years to pay it off. That is 504 payments of $100. That is $50,400 to pay off the debt. Where do you get he has to pay off $107K?
In any event, after spending 8 years in jail, the amount to pay seems confiscatory to me for something that appears to be criminal. If there was restitution maybe different but the post doesn't seem that way. I would consult with a criminal attorney and see what might be done to reduce it even further.
