Irene Shannon, a member of con artist Scott Rothstein’s inner sanctum, was charged Wednesday with helping her crooked boss run a $1.2 billion Ponzi scheme as chief financial officer and top bookkeeper at his Fort Lauderdale law firm.

Shannon, who was known by her maiden name Stay when she worked at Rothstein Rosenfeldt Adler, was charged by criminal information with money-laundering and bank fraud conspiracy. When federal prosecutors charge defendants by information, it usually indicates a plea agreement will follow. The charge carries a maximum five-year prison sentence.
