I don't know if its possible in your state, but sue him in small claims court, win a judgement and then sell the empty debt to a collection agency for five cents on the dollar. They will hound the man for years and every time he acquires something of any value, (like a car) they may be on his door step to have it seized and auctioned off to help satisfy a portion of the debt, all while the uncollected remainder continues to collect interest.
