Denver Man Sentenced to 45 Years in Federal Prison for Drug and Gun Charges

RAPID CITY - United States Attorney Ron Parsons announced today that U.S. District Judge Karen E. Schreier has sentenced a Denver, Colorado, man convicted of Conspiracy to Distribute Methamphetamine, Conspiracy to Distribute Fentanyl, and Possession of a Firearm in Furtherance of a Drug Trafficking Crime. The sentencing took place on May 22, 2026.

Juan Sertuche, 43, was sentenced to 40 years in federal prison on the charge of conspiracy to distribute methamphetamine and fentanyl charges and five years in federal prison on the firearm charge. The sentences were ordered to be served consecutively. Sertuche was also ordered to serve five years of supervised release following service of his term of imprisonment, and to pay a $300 special assessment to the Federal Crime Victims Fund.

Sertuche was indicted for all three charges by a federal grand jury in June 2025 and was subsequently convicted by a federal trial jury of all charges following a three-day jury trial in January of this year.

Between 2002 and September 2023, Sertuche led a drug distribution conspiracy and provided approximately 500 pounds of methamphetamine and more than 33,000 fentanyl pills to multiple sub-distributors to be further distributed in the Rapid City and Pine Ridge areas of South Dakota. On one occasion, law enforcement conducted a traffic stop of couriers who Sertuche had directed to travel from Denver to the Rapid City area. During the traffic stop, law enforcement discovered 19 pounds of methamphetamine intended to be further distributed in the Rapid City area. In September 2023, Sertuche was arrested following a traffic stop in Jackson County where he was found to be in possession of approximately 1,500 fentanyl pills that he intended to further distribute.

Following his arrest, Sertuche continued to direct others he was conspiring with to continue the drug distribution efforts, including by collecting money and making trips to Denver to pick up methamphetamine and fentanyl. Sertuche also directed another person on several occasions to collect numerous firearms that were part of his drug dealing to Denver to be traded for methamphetamine. Law enforcement was able to recover those firearms, including two fully automatic machine guns, before they could be taken and used as currency for drugs.

This case was investigated by the South Dakota Division of Criminal Investigation, Pennington County Sheriff's Office, Rapid City Police Department, South Dakota Highway Patrol, Wyoming State Highway Patrol, and the North Metro Denver Drug Task Force. Supervisory Assistant U.S. Attorney Benjamin Patterson and Assistant U.S. Attorney Paige Petersen prosecuted the case.

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