Minneapolis Star Tribune (01/19/12) Paul Walsh

The owner of Minneapolis-based Olen Staff Co., Doris Ruiz, pled guilty in federal court on charges that she failed to pay $150,000 in payroll taxes and $276,987 to cover the employers share of FICA taxes. In 2008, federal investigators shut down Olen after court affidavits alleged that Ruiz placed illegal immigrants with regional businesses, provided false documentation, and did not pay taxes for herself or workers for several years. Ruiz faces a maximum penalty of five years in prison when she is sentenced.
