A Connecticut woman has pleaded guilty to a conspiracy charge related to her involvement in an IRS impersonation scam that impacted more than 500 people between the U.S. and Canada.

Nancy Frye, of Bristol, entered her guilty plea in a Hartford federal court Monday. The 51-year-old is facing a maximum of 20 years in prison.

Court records show Frye was paid about $500 a day as a runner for those in the scam posing as IRS agents. The agents would call taxpayers, threatening with lawsuits or fines unless they made payments. Frye and others she recruited would then collect the money that was wired to specific bank accounts.

Between October 2015 and May 2016, Frye had collected about $580,000 in wired funds.

Her sentencing is scheduled for Sept. 20.
