LARIMER COUNTY, Colo. — A Larimer County child welfare caseworker who resigned in September after her supervisors noted concerns has been arrested on 99 charges.

Sandra Spraker, 45, of Wellington, was arrested on suspicion of falsifying documents, submitting fraudulent reimbursement requests, and other crimes while working as a Child Protection Services caseworker with the Larimer County Department of Human Services.

She was hired by the department in April 2022 and began working as a caseworker that October. Her supervisors “noted performance concerns and began reviewing her assigned cases more closely” in the early summer of 2023. Spraker was placed on administrative leave on Sept. 8 and resigned on Sept. 15.

The Larimer County Department of Human Services found “significant inconsistencies in Spraker’s official documentation,” which included falsified case reports and reimbursement requests for travel that never happened, according to the Larimer County Sheriff’s Office. The department contacted the sheriff’s office, which began a criminal investigation.
