United States Attorney Brendan V. Johnson announced that a Lower Brule, South Dakota, man charged with Simple Assault of a Child under 16 years of age pled guilty to and was sentenced on October 6, 2014, by U.S. Magistrate Judge Mark A. Moreno.

Marvin Grassrope, Jr., age 19, was sentenced to 18 months of probation and $25 to the Federal Crime Victims Fund.

The conviction stems from an incident that took place on or about October 5, 2013, when Grassrope inappropriately touched a juvenile female.

The investigation was conducted by the Federal Bureau of Investigation. The case was prosecuted by Assistant U.S. Attorney Thomas J. Wright.
