63 Charged in South Dakota Meth and Fentanyl Trafficking Crackdown

Northeast Radio SD News – South Dakota - Federal prosecutors have successfully dismantled four major drug trafficking organizations responsible for flooding South Dakota communities with massive quantities of methamphetamine and fentanyl. The coordinated multi-agency operations have resulted in federal charges against 63 defendants and secured more than 660 years in federal prison sentences, with additional cases still pending.

United States Attorney Ron Parsons announced the landmark results, emphasizing the devastating human cost of the narcotics trade.

Unprecedented Narcotics Seizures

The dismantled organizations pumped staggering amounts of lethal narcotics into the state over recent years. Over the course of the long-term investigations, authorities seized and tracked the following:

·         More than 1,000 pounds of methamphetamine were trafficked into South Dakota.

·         Tens of thousands of fentanyl pills and multiple kilograms of fentanyl powder.

·         Several million dollars in traced money laundering proceeds.

·         Federal convictions for 54 of the 63 charged defendants to date.

The Four Targeted Organizations:

The Quantiae Harris Organization, operating out of California and Nevada, this 26-defendant network was the first known group to introduce highly lethal fentanyl powder into the Sioux Falls market. The group initially shipped drugs via the U.S. Mail and operated out of local hotels before transitioning to Airbnbs and using rental vehicles equipped with hidden compartments.

On June 24, 2026, the organization’s leader, 49-year-old Quantiae Harris, was sentenced to 33 years in federal prison. U.S. District Judge Karen E. Schreier noted the drug quantities involved in the Harris case were among the highest she had seen in her more than 25 years on the federal bench.

The Juan Sertuche Organization. This network maintained a two-decade-long pipeline sourcing methamphetamine from Mexican cartels through Colorado and into Western South Dakota, specifically targeting the Rapid City area and the Pine Ridge Reservation. The group’s leader, Juan Sertuche, continued to coordinate drug deals and direct associates to trade firearms for narcotics even after his arrest. Following his conviction, Sertuche received a 45-year federal prison sentence.

The Matthew Shade Organization sourced narcotics from Mexico through Arizona; this operation funneled approximately 200 pounds of methamphetamine into the Sioux Falls suburbs. Authorities intercepted cross-country vehicle deliveries and mail parcels filled with cash and drugs. Shade, the local leader based in Tea, South Dakota, was sentenced to over 21 years in federal prison.

The Darrel Devorce Organization. This network operated a five-year methamphetamine pipeline from San Jacinto, California, to Sioux Falls. The operation laundered over $700,000 using digital payment platforms like Cash App, Zelle, and Western Union to conceal the origins of the money and the leader’s involvement. Devorce was ultimately sentenced to 33 years in federal prison.

A Broader National Strategy

These localized takedowns are a core component of “Operation Take Back America,” a nationwide initiative leveraging the U.S. Department of Justice’s full resources to eliminate transnational criminal organizations and illegal drug trafficking.

According to the U.S. Attorney’s Office, the comprehensive strategy aligns with directives set in motion by President Trump to achieve the total eradication of cartels on American soil.

With multiple defendants still awaiting trial and new indictments continuously being returned by federal grand juries, authorities stress that these four major takedowns mark the beginning of a sustained effort, rather than the end.
