For Immediate Release
U.S. Attorney's Office, District of South Dakota

United States Attorney Randolph J. Seiler announced that a Cherry Creek, South Dakota, man convicted of Failure to Register as a Sex Offender was sentenced on February 13, 2017, by U.S. District Judge Roberto A. Lange.

Dewey Marrowbone, age 48, was sentenced to 15 months in custody, 5 years of supervised release, and a special assessment to the Federal Crime Victims Fund in the amount of $100.

Marrowbone was indicted by a federal grand jury on October 12, 2016. He pled guilty on December 12, 2016.

Marrowbone had previously been convicted of a sex offense in federal court which requires him to register as a sex offender for the rest of his life. He was previously convicted for failing to register as a sex offender. Marrowbone was released from custody in Florence, Colorado, on August 10, 2016. He was to report to the Community Alternatives of the Black Hills the following day. He did not do so. He was on absconder status until August 25, 2016. The conviction stems from the fact that Marrowbone failed to register as a sex offender, as required by federal law, between August 13, 2016, and August 25, 2016.

This case was investigated by the U.S. Marshals Service. Assistant U.S. Attorney Jay Miller prosecuted the case.

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