An Eyota, Minn., woman allegedly used at least 31 aliases in 2013 to obtain prescription drugs, according to court documents.

Nanci Mae Dusso, 50, was charged in federal court Thursday with three counts of social security fraud and one count of obtaining a controlled substance by fraud, according to the documents.

Dusso visited Mayo Clinic satellite locations complaining of shoulder pain, according to the U.S. attorney's office. Using one of her aliases, Dusso would tell doctors she was in town visiting a relative who had cancer. She used the false identities to obtain Hydrocodone, Oxycodone and Codeine, a news release from the U.S. attorney's office said.

Dusso may have obtained more than 6,000 opiates and visited more than 150 doctors in Minnesota and Wisconsin since 2008, according to court documents.

Dusso and her lawyer could not immediately be reached for comment Friday.

If Dusso's convicted, she could receive a statutory maximum sentence of four years for fraudulantly obtaining a controlled substance and five years for social security fraud charges.
