FORT LAUDERDALE, Fla. — A former executive at the South Florida law firm run by convicted Ponzi scheme operator Scott Rothstein has been sentenced to 10 years in prison for her role in the $1.2 billion scam.

A federal judge in Fort Lauderdale imposed the sentence Friday on 43-year-old Debra Villegas. She is the former chief operating officer at Rothstein’s now-defunct law firm, Rothstein Rosenfeldt Adler. Villegas pleaded guilty in June to money laundering conspiracy and admitted helping Rothstein draft fake legal documents.
