A South Florida attorney is facing a prison sentence after she was convicted for playing a role in Ponzi schemer Scott Rothstein's $1.2 billion fraud scam.

A federal judge in West Palm Beach is set Tuesday to sentence Christina Kitterman. She was convicted in February by a jury on three wire fraud counts, each of which carries a potential 20-year prison sentence. Kitterman's attorney is seeking a more lenient sentence.

Trial testimony showed that Rothstein asked Kitterman to pose as a Florida Bar official in a conference call with nervous investors. The Ponzi scheme involved investments in fake legal settlements.

Kitterman so far is the only one of about 20 people charged in the fraud case to go to trial. Rothstein is serving a 50-year prison sentence after pleading guilty.
