Earlyne C. Weigel, 57, pleaded guilty to one count of theft of government money.
In her plea, she admitted that in March 2003 she began receiving benefits from Social Security. Her benefits were adjusted to take into account her household income, including income from her husband.
In 2005, she went to the Social Security field office in Hays, and falsely reported that she no longer lived with her husband. As a result, from 2004 to 2010 she received more than $43,473 in Supplemental Security Income benefits to which she was not entitled.
In November 2008, investigators interviewed her husband, who told them that he and his wife had never lived apart while married.
Weigel also applied for and received Medicaid coverage beginning in 2004. Her Medicaid coverage was contingent on her eligibility for Supplemental Security Income benefits. From 2004 to 2010 she fraudulently received more than $60,919 in Medicaid benefits.
Sentencing is set for Dec. 9.
Weigel faces a maximum penalty of 10 years in federal prison and a fine up to $250,000.
