Sioux Falls Man Sentenced to 21 Months in Federal Prison for Failing to Register as a Sex Offender

SIOUX FALLS - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Karen E. Schrier has sentenced a Sioux Falls, South Dakota, man convicted of Failure to Register as a Sex Offender. The sentencing took place on November 18, 2024.

Tanner Kills Enemy, 26, was sentenced to one year and nine months in federal prison, followed by five years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund. The sentence was ordered to run consecutively to a state sentence Kills Enemy is currently serving at Mike Durfee State Prison for Aggravated Assault.

Kills Enemy was indicted for Failure to Register as a Sex Offender by a federal grand jury in May 2024. He pleaded guilty in October 2024.

Kills Enemy is required to register as a sex offender under the Sex Offender Registration and Notification Act as a result of a conviction in October of 2020 for Sexual Abuse in Rosebud Sioux Tribal Court. On February 1, 2024, while on federal supervised release for a prior Failure to Register conviction, Kills Enemy left his registered address in Sioux Falls, South Dakota, and failed to update the sex offender registry with his new address or location. Kills Enemy’s whereabouts were unknown to registration officials until he was arrested on March 15, 2024.

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.
