Winner Man Sentenced to 10 Years in Federal Prison for Abusive Sexual Contact with a Child

PIERRE - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Eric C. Shulte has sentenced a man from Winner, South Dakota, who was convicted of Abusive Sexual Contact with a Child. The sentencing took place on August 5, 2025.

Clayton Spotted Calf, age 30, was sentenced to 10 years in federal prison, followed by 5 years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Spotted Calf was indicted by a federal grand jury in June 2024. He pleaded guilty on April 14, 2025.

The conviction stems from conduct that occurred between approximately April 2015 and June 2017 in Todd County, South Dakota, within the Rosebud Sioux Indian Reservation. On more than one occasion during that period, Spotted Calf engaged in sexual contact with a child who was then between the ages of six and eight years old.

This matter was prosecuted by the U.S. Attorney’s Office because the Major Crimes Act, a federal statute, mandates that certain violent crimes alleged to have occurred in Indian Country be prosecuted in Federal court as opposed to State court.

This case was investigated by the South Dakota Division of Criminal Investigation and the FBI. Assistant U.S. Attorney Kirk Albertson prosecuted the case.

This case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse, launched in May 2006 by the Department of Justice. Led by the U.S. Attorneys’ Offices and the DOJ’s Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute individuals who exploit children, as well as identify and rescue victims.

Spotted Calf was immediately remanded to the custody of the U.S. Marshals Service.
