Between 2007 and 2014, prosecutors say a Martha's Vineyard woman paid Johnson more than $3.5 million for services that claimed to rid the woman of demons. Prosecutors say Johnson didn't report the income and tried to hide the money so she wouldn't have to pay taxes on it.
Johnson pleaded guilty in the federal court in Boston Thursday and has agreed to repay the woman. She's expected to be sentenced in January. Johnson's attorney declined to comment.
