Aaron Michael Hymas, 38, and his wife, Tiffany Kim Hymas, 37, have entered plea agreements with federal prosecutors.

The Hymases are slated to change their plea 10 a.m. Oct. 18 before Judge William B. Shubb.

A Boise federal grand jury on Feb. 15 handed down a 17-count indictment against the former Treasure Valley couple for wire, loan and bankruptcy fraud. The Hymases, who now live in Utah, pleaded not guilty at their March 7 arraignment.

Under the plea agreements filed last month, each will plead guilty to one count of wire fraud for making false statements on a $295,600 residential loan application. The charge is punishable by up to 20 years in prison, up to three years supervised release and a maximum fine of $250,000.

A sentencing date has not yet been set.

Aaron Hymas was co-owner of the now defunct Crestwood custom home-building business. His business partner, Justin Walker, died in an airplane crash in 2009.

The Hymases’ case is part of a multiyear FBI and IRS investigation of mortgage fraud activity related to Crestwood, which involved multiple defendants who used fraudulent loans to profit from real estate transactions.

To date, nine Hymas family members or associates have been sentenced in related federal cases, including Michael J. Hymas, Shauntee K. Ferguson, Christopher R. Georgeson, Stanley J. Ferguson, Brent Bethers, Shane Merlin Hymas, Laurie Krechelle Hymas, Melody Covino Redondo and Paul Redondo.

Of the nine who pleaded guilty, several served time in federal prison. Aaron’s father, Michael Hymas, was released in June; Melody Redondo’s was released last month. Stanley Ferguson was released from prison in December; Shane Hymas was released in January.

Two other family members, Travis and Season Hymas, are awaiting sentencing or trial.

In June, a jury found Travis Hymas guilty on five counts of wire fraud. His sentencing is set for 10:30 a.m. Tuesday before Judge Edward J. Lodge.

Season Hymas’ trial is set for Nov. 13.
