November 1, 2023

Brighton, CO —District Attorney Brian Mason and the Drug Trafficking Unit of the Adams County District Attorney's Office, the North Metro Task Force, and the Drug Enforcement Administration Rocky Mountain Field Division are announcing the grand jury indictment of nine members of a Mexican drug cartel who allegedly funneled large quantities of fentanyl, methamphetamines, and cocaine into Adams County, other parts of Colorado, Oregon, Nevada, and Arizona. 

Operation Dress for Less investigated the distribution of fentanyl, methamphetamines, and cocaine between the Sinaloa Cartel in Mexico and the greater Adams County area. The North Metro Task Force identified local distributors in Westminster and Federal Heights. Through the course of this operation, the task force uncovered an entire distribution network of co-conspirators that connected Mexico to Colorado, Oregon, Nevada and Arizona. 

An Adams County Grand Jury indicted nine members of the Sanudo-Rivera Drug Trafficking Organization who allegedly acted as a direct cartel pipeline for the distribution of fentanyl into the greater Adams County area. 

In addition to the indictment, a number of seizures occurred as a result of this operation. 
  • 84.3 pounds of fentanyl pills (approximately 381,824 pills)
  • 66 pounds of methamphetamine
  • 1.4 kilos of cocaine
  • 14g of heroin
  • 1 active methamphetamine lab
  • 5 guns
  • $93,000
The 47-count indictment was signed on September 25, 2023. 
"I created an experienced Drug Trafficking Unit in the District Attorney's Office to take down large-scale drug dealers and break pipelines that feed into our local communities and destroy lives in the process. The joint efforts of the District Attorney's Office, the North Metro Task Force, and the DEA Rocky Mountain Field Division in this investigation truly shows our commitment to dismantling these troublesome and deadly operations. I'm proud of the work of my staff and our partners, and it is encouraging to see it come to fruition through this expansive indictment; however, the work continues and this is just one step in the process of ridding our communities of these drug cartels that do our residents a great deal of harm."
District Attorney Brian Mason

“The DEA continues to be laser focused on the Sinaloa Cartel and their network. The significant seizures of fentanyl and methamphetamine made in the Denver-Metro area over the course of this investigation demonstrates the commitment law enforcement in the region has to addressing the problem, but also the influence the cartels have in our communities. The work by the investigators and prosecution team on this case is commendable and will continue.” 
Acting Special in Charge David Olesky, DEA Rocky Mountain Field Division

“The Detectives and Investigators at North Metro Task Force are deeply driven to dismantle Drug Trafficking Organizations. Especially those criminal organizations whom traffic in Fentanyl. The North Metro Task Force, along with a partnership with the Drug Enforcement Administration, intercepted well over 300,000 dosage units of Fentanyl. Our Investigators worked tirelessly on this case, to prevent this number of narcotics from reaching the streets of Adams and Broomfield Counties. I couldn’t be prouder of the work accomplished by the men and women who worked on this case.”  
Commander John Bitterman, North Metro Task Force/Adams County Sheriff's Office
