Black Spotted Horse was indicted by a federal grand jury on August 11, 2022. He pled guilty on May 3, 2021.

The conviction for Assault With a Dangerous Weapon stemmed from an incident that occurred in Norris, South Dakota, on June 14, 2020.

Black Spotted Horse and the victim got into an argument, at which point Black Spotted Horse produced a knife and stabbed the victim in the chest. He then fled the scene.

Black Spotted Horse was convicted of Sexual Abuse of a Minor in March 2010. As a result of this conviction, he is required to register as a sex offender and to update his registration within three business days of relocation or changing employment. Between 2013 and 2018, Black Spotted Horse was convicted of Failure to Register as a Sex Offender on four separate occasions. In January 2020, Black Spotted Horse was released from custody and began a period of supervised release. He initially registered and resided at a residence in Rapid City. In April 2020, he moved from his registered address, but did not update his registration. His whereabouts were unknown until his arrest on June 14, 2020.

This case was investigated by the Rosebud Sioux Tribe Law Enforcement Services and the U.S. Marshals Service. Assistant U.S. Attorney Kirk Albertson prosecuted the case.

Black Spotted Horse was immediately turned over to the custody of the U.S. Marshals Service.
