Former D.C. tax examiner sentenced to 30 months in prison for fraud A former District tax examiner was sentenced to 30 months in prison Monday for issuing more than $400,000 in fraudulent tax refunds. Mary Ayers-Zander, 47, of College Park, pleaded guilty to federal wire fraud in October 2011, after an investigation found that she had accessed taxpayer accounts and credited them with fraudulent withholding credit adjustments, authorities said. The majority of the credits, $365,281, went to her personal accounts, but $46,175 went to taxpayers, according to a statement from the U.S. attorney's office. "Mary Ayers-Zander treated the D.C. treasury like her personal piggy bank," U.S. Attorney Ronald Machen said in the statement. Ayers-Zander will pay $413,651 in restitution to the D.C. government as part of her plea agreement, authorities said.
