Eagle Butte Man Sentenced to Over 10 Years in Federal Prison Following Conviction at Trial for Sexual Abuse

RAPID CITY – United States Attorney Ron Parsons announced today that an Eagle Butte man was sentenced to 10 years and one month in federal prison.
24-year-old Emanual Semon was also sentenced to five years of supervised release.
Semon was found guilty following a three day jury trial in May 2026. The convictions stem from an incident that occurred at a residence in the Pine Ridge Indian Reservation in July 2024.
At trial, the evidence established that on the afternoon of July 3, 2024, Semon engaged in sexual activity with a juvenile female without her consent. Semon stopped when an adult entered the room and interrupted him.
This matter was prosecuted by the U.S. Attorney’s Office because the Major Crimes Act, a federal statute, mandates that certain violent crimes alleged to have occurred in Indian Country be prosecuted in Federal court as opposed to State court.
This case was investigated by the FBI and the Oglala Sioux Tribe Department of Public Safety.
This case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse, launched in May 2006 by the Department of Justice.
