Stephanie Lambert of Roscoe pleaded guilty Tuesday to felony neglect and filing false insurance claims.
As administrator of Encore Senior Living in Janesville, Wisconsin, Lambert was responsible for monitoring any changes in residents' medical conditions. She was accused of concealing the resident's condition and falsifying records to prevent superiors from knowing about the lack of treatment.
The 77-year-old resident died of an infection in April 2002.
The charges against Lambert carry a maximum 26-and-a-half years in prison and $120,000 in fines.
