Mission Man Sentenced for Failure to Register As a Sex Offender

United States Attorney Randolph J. Seiler announced that a Mission, South Dakota, man convicted of Failure to Register as a Sex Offender was sentenced on December 12, 2017, by U.S. District Judge Roberto A. Lange.

Adrian William Fast Dog, age 37, was sentenced to 18 months in custody, followed by 5 years of supervised release, and a special assessment to the Federal Crime Victims Fund in the amount of $100.

Fast Dog was indicted by a federal grand jury on August 16, 2017.  He pled guilty on October 30, 2017.

The conviction stems from Fast Dog failing to register as a sex offender as required by federal law between July 7, 2017, and August 4, 2017.  Fast Dog had previously been convicted of a sex offense in federal court, which requires him to register for the rest of his life.

This case was investigated by the U.S. Marshals Service.  Assistant U.S. Attorney Meghan N. Dilges prosecuted the case.

Fast Dog was immediately turned over to the custody of the U.S. Marshals Service.
