United States Attorney Alison J. Ramsdell announced that a Ring Thunder, South Dakota, man has been indicted by a federal grand jury for Sexual Abuse of a Minor and Aggravated Incest.

Marshall Knife, age 38, was indicted on April 12, 2022.  He appeared before U.S. Magistrate Judge Mark A. Moreno on April 29, 2022, and pled not guilty to the Indictment.

The maximum penalty upon conviction is up to 15 years in federal prison and/or a $250,000 fine, up to life of supervised release, and $100 to the Federal Crime Victims Fund.  Restitution may also be ordered.

The Indictment alleges that between January 1, 2019, and November 30, 2021, near Ring Thunder, Knife knowingly engaged in, and attempted to engage in, a sexual act with a minor female.


The charges are merely accusations and Knife is presumed innocent until and unless proven guilty. 

The investigation is being conducted by the Federal Bureau of Investigation.  Assistant U.S. Attorney Abby Roesler is prosecuting the case.   

Knife was remanded to the custody of the U.S. Marshals Service pending trial.  A trial date has not been set.
