RAPID CITY – United States Attorney Ron Parsons announced today that U.S. District Judge
Camela C. Theeler has sentenced a Rapid City, South Dakota, man convicted of Abusive Sexual
Contact. The sentencing took place on August 31, 2026.

William Beane Davis, 38, was sentenced to nine years in federal prison, followed by five years of
supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Davis was indicted for Aggravated Sexual Abuse of a Minor and Distribution of a Controlled
Substance to an Individual under 21 by a federal grand jury in July 2025. He pleaded guilty on May
29, 2026.

Davis was in an intimate relationship with a female who was the mother of the female juvenile victim
in this case. He served as a father figure to the victim and was involved in the victim’s life until the
Spring of 2025. At that time, the victim disclosed, Davis sexually abused her on more than one
occasion.

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 Federal Bureau of Investigation and the Oglala Sioux Tribe
Department of Public Safety. Assistant U.S. Attorney Megan Poppen prosecuted the case.
Davis was immediately remanded to the custody of the U.S. Marshals Service.
