For attorney Christina Kitterman, con man Scott Rothstein was her law firm boss, her professor, her lover and her benefactor. She called him as her key defense witness in the first criminal trial to reach court in the collapse of his $1.2 billion Ponzi scheme.

Now he’s the reason she’s going to prison for five years after duping her into making a 10-minute telephone call that helped extend the life of his settlement financing fraud for six months before it collapsed in 2009. Kitterman made a conference call from her car pretending to be a Florida Bar official offering New York hedge fund managers an explanation for why his money was tied up.
