She was found guilty April 15 of money laundering, racketeering and mail fraud and faced a maximum 55-year prison term at her sentencing, which was scheduled for July 24.
A spokesman for the U.S. Attorneys Office in Washington, which prosecuted Palfrey, declined to comment.
Prosecutors estimated she would have received a sentence between 57-71 months, about six years, because of sentencing guidelines and other factors that would have been taken into account.
