Lame Deer man sentenced to over 15 years in prison for rape on Northern Cheyenne Indian Reservation

BILLINGS – A Lame Deer man who raped a woman on the Northern Cheyenne Indian Reservation was sentenced today to 188 months in prison to be followed by15 years of supervised release, U.S. Attorney Kurt Alme said.

Adriano Sparkxxx LeBeaux, 21, was found guilty at trial in October 2024 of aggravated sexual abuse as charged in an indictment.

U.S. District Judge Susan Watters presided.

In court documents and at trial, the government alleged that on March 8, 2023, the victim, identified as Jane Doe, met up with LeBeaux at a residence in Lame Deer, on the Northern Cheyenne Indian Reservation. LeBeaux told Doe the police were on their way to search the house and that they needed to hide in the basement. Jane Doe had been drinking and did not want to be arrested because Northern Cheyenne is a dry reservation. Hiding in the basement seemed like a good idea to Jane Doe.

While in the basement, LeBeaux told Jane Doe to lie down in a corner on the floor, and she fell asleep or passed out. At some point, Jane Doe awoke to LeBeaux holding a knife to her throat and then he raped her. Jane Doe left the residence and went to the Indian Health Service Clinic where she underwent a sexual assault exam. An analysis of DNA indicated LeBeaux was the contributor to male DNA identified in the sexual assault exam.

Assistant U.S. Attorneys Lori Suek and Paul Vestal prosecuted the case, and the investigation was conducted by the FBI, BIA and Northern Cheyenne Investigative Services.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
