Manderson Man Found Guilty Following a Jury Trial
For Immediate Release
U.S. Attorney's Office, District of South Dakota
RAPID CITY - United States Attorney Alison J. Ramsdell announced that a jury has convicted Gabriel White Plume, Sr., age 39, of Pine Ridge, South Dakota, 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 following a four-day jury trial in federal district court in Rapid City. The verdict was returned on July 28, 2023.
White Plume faces any term of years up to life in custody and/or up to a $5,000,000 fine, a minimum of five years up to life of supervised release, and a $100 special assessment to the Federal Crime Victims Fund for each count.
White Plume was indicted by a federal grand jury in February of 2023.
The charges related to 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.
A presentence investigation was ordered and a sentencing date was set for October 18, 2023. The defendant was remanded to the custody of the U.S. Marshals Service.
