A sentencing hearing for Ashley Viken is expected to be held in February after she admitted to stealing $119,000 while working as an accountant at the $2.3 billion Black Hills Federal Credit Union in Rapid City, S.D., according to federal court documents.

In exchange for her guilty plea, federal prosecutors agreed to drop 23 felony counts of theft by a credit union employee, court documents showed.

Beginning in July 2022 and continuing through March 2024, Viken wrote cashier’s checks on a Black Hills, account then deposited those checks into her accounts at two small South Dakota credit unions.
