Eagle Butte Man Sentenced for Failure to Register as a Sex Offender

Acting United States Attorney Randolph J. Seiler announced that an Eagle Butte, South Dakota, man convicted of Failure to Register as a Sex Offender was sentenced on June 22, 2015, by U.S. District Judge Roberto A. Lange.

David Marrowbone, age 51, was sentenced to 15 months in custody, followed by 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 June 10, 2014.  He pled guilty to the Indictment on March 26, 2015.

The conviction arose from Marrowbone’s failure to register and update his sex offender registration from between February 3, 2014, and March 13, 2014, as required by federal law. Marrowbone was required to register due to his federal conviction in 1982 for Assault with Intent to Commit Rape.

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

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