St. Paul, MN (KROC-AM News) - Two Minnesota women charged with being part of what has been described as the largest Medicaid fraud case in state history have been found guilty of racketeering and theft by swindle charges.

A news release issued by the Minnesota Attorney General’s Office says Lillian Richardson and Bridgett Burrell were the last of the seven people charged in the case to be convicted. The other five previously pleaded guilty.

"Hundreds of thousands of dollars of claims were the result of illegal kickback or check-splitting agreements between clients and employees, many of whom were friends and family members of Richardson and Burrell," the release said.

Richardson was accused of being the ringleader of a scam that, according to prosecutors, resulted in the theft of over $7.5-million from the government health care program.

Minnesota court records show she was convicted of a Medicaid Fraud Charge in 2012 and was sentenced to 10-years on probation, but that was amended in 2017 and was ordered to serve a 21-month prison sentence. Richardson's original sentence included $65,000 in restitution and she still owes over $64,000.
