Box Elder Man Sentenced For Failure To Register As A Sex Offender

United States Attorney Brendan V. Johnson announced that a Box Elder, South Dakota, man convicted of Failure to Register as a Sex Offender was sentenced on February 2, 2015, by U.S. District Judge Roberto A. Lange.

Dewey Shane Marrowbone, age 45, was sentenced to 14 months in custody, 5 years of supervised release, and a $100 special assessment to the Federal Crime Victims Fund.

Marrowbone was indicted by a federal grand jury on September 16, 2014 for Failure to Register as a Sex Offender, and pled guilty on November 17, 2014.

The conviction stems from Marrowbone’s failure to register and update his sex offender registration between July 4, 2014, and August 20, 2014. Marrowbone was convicted of Sexual Abuse in 2006, and therefore required by federal law to register and update his place of residence.

This case was investigated by the U.S. Marshals Service and the Cheyenne River Sioux Tribe Law Enforcement Division.  Assistant U.S. Attorney Mikal Hanson prosecuted the case.

Marrowbone was immediately turned over to the custody of the U.S. Marshals Service to begin serving his sentence.
