Manderson Man Sentenced to Forty Years in Federal Prison

RAPID CITY - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Karen E. Schreier has sentenced a Manderson, South Dakota, man convicted of Aggravated Sexual Abuse by Use of Force, Assault Resulting in Serious Bodily Injury, Assault by Strangulation and Suffocation, Distribution of a Controlled Substance to an Individual Under 21, Tampering with a Witness, Assault Resulting in Substantial Bodily Injury to a Spouse, Intimate Partner, or Dating Partner, two counts of Assault Resulting in Serious Bodily Injury, and Sexual Abuse. The sentencing took place on October 26, 2023.

Gabriel White Plume, 39, was sentenced to 40 years in federal prison on the charges of Aggravated Sexual Abuse by Use of Force, Distribution of a Controlled Substance to an Individual Under 21, and Assault Resulting in Serious Bodily Injury, 20 years on the charge of Tampering with a Witness, 10 years on the two charges of Assault Resulting in Serious Bodily Injury and Assault by Strangulation and Suffocation, and five years on the charge of Assault Resulting in Substantial Bodily Injury to a Spouse, Intimate Partner, or Dating Partner. The prison sentences were ordered to be served concurrently and will be followed by six years of supervised release. He was also ordered to pay a total of $800 in special assessments to the Federal Crime Victims Fund.

White Plume was indicted for the charges by a federal grand jury in February of 2023. He was found guilty following a federal jury trial in Rapid City, South Dakota, in July of 2023.

The conviction stems from White Plume physically and sexually abusing his dating partner by the use of force at Manderson. The victim sustained substantial bodily injury from the physical assault and serious bodily injury from the sexual assault. Prior to being charged federally, White Plume was able to obtain a cellular device in his cell while incarcerated at Pine Ridge. White Plume used the cellular device to access Facebook in order to corruptly persuade his victim into dropping tribal charges. 

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. Assistant U.S. Attorneys Megan Poppen and Anna Lindrooth prosecuted the case.

White Plume was immediately remanded to the custody of the U.S. Marshals Service.
