Rep. Tierney's wife to plead guilty to hiding her brother's offshore gambling business

The wife of Massachusetts lawmaker Rep. John Tierney (D) will plead guilty to charges that she helped her brother conceal what authorities say was a multi-million dollar illegal offshore gambling business.

Federal prosecutors said Tierney's 59-year-old wife Patrice Tierney is expected to plead guilty Monday in U.S. District Court in Boston to four counts of aiding and abetting the filing of false tax returns, according to a report from The Associated Press late Tuesday. 

Robert Eremian, Tierney's fugitive brother, and another sibling face charges including racketeering, money laundering and operating an illegal gambling business.

The seven-term lawmaker says his wife believed her brother's money came from selling or licensing software to legal Internet gambling businesses.

Tierney says his wife accepts full responsibility for being "willfully blind" to what her brother was doing.
