Colorado Woman Sentenced to Nearly 23 Years in Federal Prison for Conspiring to Distribute Huge Quantities of Methamphetamine in Pierre, Rapid City, and in Several Indian Reservations in South Dakota

PIERRE - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Eric C. Schulte has sentenced a Denver, Colorado, woman convicted of Conspiracy to Distribute a Controlled Substance. The sentencing took place on March 5, 2025.

Rikki Renee Barrowman, a/k/a Juree T Rials, age 34, was sentenced to 22 years and 11 months in federal prison, followed by five years of supervised release, a $1,000 fine, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Barrowman was indicted for  Conspiracy to Distribute a Controlled Substance by a federal grand jury in Febuary 2024. She pleaded guilty on December 5, 2024.

The conviction stemmed from a drug conspiracy beginning in January 2021 and continuing until July 2022. Barrowman was involved in an extensive conspiracy with several other individuals to distribute methamphetamine in and around western and central South Dakota, including within the Pine Ridge Sioux Indian Reservation, the Cheyenne River Sioux Indian Reservation, and the Rosebud Sioux Indian Reservation, as well as in Rapid City and Pierre. This conspiracy involved approximately 65 kilograms of methamphetamine. Barrowman was the source of supply of methamphetamine in Denver. She would supply various individuals who would then transport the methamphetamine to South Dakota where it was further distributed. As part of the conspiracy firearms were traded for narcotics.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.

This case was investigated by the Cheyenne River Sioux Tribe Law Enforcement Services, the Northern Plains Safe Trails Drug Enforcement Task Force, and the FBI. Assistant U.S. Attorney Meghan N. Dilges prosecuted the case.

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