A jury found a Colorado Springs woman guilty of conspiracy to file false claims for IRS refunds and seven counts of aiding and abetting in making and presenting false claims for refunds, according to news from United States Attorney John Walsh and IRS Criminal Investigation Special Agent in Charge Stephen Boyd.

Christina Portillos, 36, was indicted by a federal grand jury in April 2015, along with five co-conspirators. She was charged in a superseding indictment with seven other people on June 10, 2015. The superseding indictment charged 39 counts, including the ones she was found guilty of.

The guilty verdict came after a five-day trial and four hours of jury deliberations. Portillos will be sentenced July 29.

The jury found her guilty of receiving about $38,000 in fraudulent IRS refund checks and then provided those checks to her co-conspirators. The refunds came from false tax returns, written by Raul Caraveo and Eugene Chavez, two inmates with the Colorado Department of Corrections. The men allegedly used identifying information of fellow inmates and their relatives. They submitted tax returns from 2005 to 2013 and requested refunds from $2,491 to $3,052.

During the course of this conspiracy, more than 250 false claims for income tax refunds were submitted to the Internal Revenue Service in an attempt to receive fraudulent refunds.
