Rapid City Man Sentenced for Conspiring to Distribute Methamphetamine

RAPID CITY, S.D. - United States Attorney Alison J. Ramsdell announced today that Chief Judge Roberto A. Lange, U.S. District Court, has sentenced a Rapid City, South Dakota, man convicted of Conspiracy to Distribute a Controlled Substance. The sentencing took place on September 28, 2023.

Eugene Perez, 44, was sentenced to 11 years and five months in federal prison, followed by five years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Perez was indicted for Conspiracy to Distribute a Controlled Substance and Possession of a Firearm by a Prohibited Person by a federal grand jury in January of 2022. He pleaded guilty on June 28, 2023.

The charge stems from Perez conspiring with others to distribute multiple pounds of methamphetamine in and around Rapid City between January 2018 and December 2021.

The investigation was conducted by the Bureau of Alcohol, Tobacco, Firearms and Explosives, Unified Narcotics Enforcement Team, Pennington County Sheriff’s Office, South Dakota Department of Criminal Investigation, and the South Dakota Highway Patrol. Assistant U.S. Attorney Benjamin Patterson prosecuted the case.

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