Federal jury convicts Lame Deer man of rape on Northern Cheyenne Indian Reservation

BILLINGS - A federal jury today convicted a Lame Deer man of raping a woman in a residence on the Northern Cheyenne Indian Reservation, U.S. Attorney Jesse Laslovich said.

After a three-day trial that began on Oct. 7, the jury found the defendant, Adriano Sparkxxx LeBeaux, 20, guilty of aggravated sexual abuse as charged in an indictment. LeBeaux faces a maximum of life in prison, a $250,000 fine and five years of supervised release.

U.S. District Judge Susan P. Watters presided. The court will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors. Sentencing was set for Feb. 7, 2025. LeBeaux was detained pending further proceedings.

"LeBeaux preyed on the victim by luring her to a basement where he put a knife to her throat and raped her. Violence against women, especially sexual violence, inflicts long-lasting trauma on the victims. I am grateful the jury held LeBeaux accountable for his conduct and hope that the victim will find some measure of healing knowing that LeBeaux faces significant incarceration. I want to thank our prosecution team, the FBI, Bureau of Indian Affairs and Northern Cheyenne Investigative Services for their work on bringing LeBeaux to justice," U.S. Attorney Laslovich said.

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 the Northern Cheyenne Reservation is a dry reservation. Hiding in the basement seemed like a good idea to Jane Doe. The victim did not think LeBeaux was drinking.

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 and LeBeaux was holding her down by the neck. Jane Doe passed out, and when she awoke again, LeBeaux was holding a knife to her throat and then 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 strong support that LeBeaux was the contributor to male DNA identified in the sexual assault exam.

The U.S. Attorney's Office is prosecuting the case. The FBI, Bureau of Indian Affairs and Northern Cheyenne Investigative Services conducted the investigation.
