WICHITA — The mail fraud charges pending against Wanda Oborny, a former employee of the late Hays millionaire Earl O. Field, will not go before a jury trial until 2019.

The trial stems from an indictment filed in January 2017. The trial now is slated to start at 9 a.m. Feb. 19, 2019, before District Judge J. Thomas Marten in U.S. District Court in Wichita.

Oborny lost a probate case in Ellis County earlier, when the judge ruled the codicil she filed was not the valid last will and testament for Field, who died in 2013. The codicil would have made Oborny the biggest single beneficiary of an estate worth about $20 million.

The federal court date originally was set for May 2017 and then rescheduled for November 2017, May 2018, and then Sept. 18, 2018. Last month, the judge assigned the latest trial date of Feb. 19. 2018.

The couple who said in depositions that they had witnessed Field signing the codicil, Steve and Kathy Little, died in a murder-suicide before the probate case went to trial in Hays. Oborny is out on bond.
