Arturo Tellez-Berrelleza Gets 21 Months in Tohono O’odham Drug Smuggling Ring

PHOENIX — The last of 18 members in a Mexican drug trafficking organization that exploited the rugged terrain of the Tohono O’odham Reservation to smuggle thousands of pounds of marijuana into the U.S. has been sentenced. Arturo Tellez-Berrelleza, 32, a citizen of Mexico, was handed 21 months in federal prison by U.S. District Judge James A. Soto after pleading guilty to drug trafficking charges. The sentencing marks the end of a sprawling, multi-year crackdown targeting a network that turned tribal land into a corridor for narcotics.

Federal investigators began unraveling the operation in October 2015, when Homeland Security Investigations and the U.S. Border Patrol launched a coordinated probe into the DTO’s activities on the reservation. The smuggling ring relied heavily on “scouts” stationed on high ground for days at a time, using binoculars, radios, and cellphones to guide backpackers loaded with marijuana around patrols. “Resuppliers” kept the scouts equipped with food, weather gear, and communication tools, creating a militarized smuggling infrastructure across the desert.

Over the course of the investigation, law enforcement seized an astounding 5,478 kilograms of marijuana—enough to supply tens of thousands of street-level doses. The prosecutions spanned multiple federal dockets, including case numbers 4:17-CR-00480-JAS-BPV, 4:17-CR-00291-RCC-LAB, and 4:17-CR-00557-JAS-EJM, among others. Sentences for the 18 convicted traffickers ranged up to 37 months, reflecting the severity and scale of the operation.

The violence associated with the ring underscored its danger. On one occasion, a suspect ambushed a federal agent near a cliff with a 15- to 20-foot drop, assaulting the officer, grabbing his radio, and deliberately smashing it to prevent a backup call. The agent was pushed perilously close to the edge during the struggle—a chilling reminder of the risks faced by border enforcement personnel.

“Our office is committed to prosecuting transnational criminal organizations that seek to smuggle drugs through Arizona,” said First Assistant U.S. Attorney Elizabeth A. Strange. She credited Homeland Security Investigations and the U.S. Border Patrol Casa Grande Station for their relentless work. “HSI, along with our law enforcement partners, will continue to work tirelessly to target and dismantle organizations who seek to operate in the desert undetected,” said Scott Brown, special agent in charge of HSI Phoenix.

The case was prosecuted by Assistant U.S. Attorneys Adam Rossi and Susanna Martinez of the District of Arizona, Tucson. The investigation was conducted under the NATIVE Task Force, a specialized HSI unit focused on cross-border crime impacting tribal lands. With Tellez-Berrelleza’s sentencing, federal authorities declare this chapter closed—but the war on drug cartels using Arizona’s remote zones is far from over.
