Federal prosecutors say 54-year-old Royann Schmidgall was sentenced on Monday in U.S. District Court in Lincoln. Schmidgall must serve three years of supervised release after she leaves prison.
Schmidgall had faced 15 counts, but prosecutors agreed to drop all but one in exchange for her guilty plea.
Prosecutors say Schmidgall handled payroll and other administrative duties at Nebraska Pulmonary Specialties for 15 years. She was fired in December 2011.
