Pine Ridge Man Sentenced to Over 36 Years in Federal Prison

United States Attorney Alison J. Ramsdell announced that a Pine Ridge, South Dakota, man convicted of Discharge and Brandishing of a Firearm During a Crime of Violence, Assault with a Dangerous Weapon, Assault Resulting in Serious Bodily Injury, three counts of Failure to Register as a Sex Offender, and two counts of Possession of a Firearm by a Prohibited Person was sentenced on August 31, 2022, by U.S. District Judge Jeffrey L. Viken,

Isaac Roubideaux, age 30, was sentenced to a total of 442 months in federal prison on the eight charges of which he was convicted by a federal jury in May of 2022.  This time is to be followed by five years of supervised release.  Roubideaux was also ordered to pay $800 in special assessments to the Federal Crime Victims Fund and $900 in restitution.

Roubideaux was indicted by a federal grand jury in December of 2021.  He was found guilty of the charges following a jury trial in Rapid City, South Dakota on May 20, 2022.

The conviction stems from Roubideaux using a Savage rifle to shoot a male individual in the back as he attempted to leave Roubideaux’s residence at Pine Ridge on November 18, 2021.  The victim was paralyzed from the waist down as a result of the assault.  Roubideaux was convicted of Sexual Abuse of a Minor in 2016 and was required to register as a sex offender.  On three separate occasions between 2020 and 2021, Roubideaux failed to update and register his address consistent with the Sex Offender Registration and Notification Act.  Roubideaux, a convicted felon, who is prohibited by law from possessing firearms, possessed a KEL-TEC, .22 caliber handgun on September 26, 2021, and the Savage rifle that was used in the November 18, 2021, shooting.

This case is part of Project Safe Neighborhoods (PSN), the centerpiece of the Department of Justice’s violent crime reduction efforts.  PSN is an evidence-based program proven to be effective at reducing violent crime.  Through PSN, a broad spectrum of stakeholders work together to identify the most pressing violent crime problems in the community and develop comprehensive solutions to address them.  As part of this strategy, PSN focuses enforcement efforts on the most violent offenders and partners with locally based prevention and reentry programs for lasting reductions in crime. 

This case was investigated by the Oglala Sioux Tribe Department of Public Safety, Oglala Sioux Tribe Criminal Investigations Unit, Bureau of Alcohol, Tobacco, Firearms and Explosives, Rapid City Police Department, U.S. Marshals Service, and the FBI.  Assistant U.S. Attorneys Megan Poppen and Heather Sazama prosecuted the case.

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