The Top Cartel LEadership
At the top of the network were figures who shaped strategy and direction, but no single individual defined or controlled the system.

Joaquin “El Chapo” Guzmán prior to his capture in 2014. Behind the mythology was a leader operating within a structured network that extended far beyond any one individual.

Aureliano “Guano” Guzmán-Loera, a senior figure within the organization. Leadership within the network was distributed, allowing operations to continue regardless of individual arrests.
Ismael “El Mayo” Zambada-García, long considered one of the most enduring figures in the network. His longevity reflects the adaptability and resilience of the system itself.

The Plaza Bosses
Adelmo “El Memo” Niebla-Gonzalez while controlling the Sonoyta, Sonora plaza. As a plaza boss, he oversaw the movement of drugs and humans and coordinated smuggling operations across the border.

Baldomero “Mero” Fernández-Beltrán, Memo’s right-hand man, escorted by US Marshals during extradition to the United States in 2025. Roles like his ensured continuity beneath plaza-level leadership.
Plaza Boss Adrian Del Cid Buelna on the day I arrested him in Arivaca, AZ on February 9, 2006. SRT executed the search warrant at Ricardo’s trailer and found him hiding under a bed. Agents didn’t search the jacket he is wearing in this photo and I later learned that he had a .38 Super pistol in the pocket. Such mistakes have proven lethal for law enforcement officers in the past.
Ignacio “Nacho” Paez-Soto following his arrest in Mexico in 2009. As a plaza boss operating across Sonora and Arizona, he helped coordinate cross-border movement within a larger, structured network.
The Next Layer

Ovidio “Raton” Guzmán-López during his extradition to the United States in 2023. His rise reflected how established networks adapted by elevating the next layer of leadership.
Joaquín “Guero” Guzmán-López, son of El Chapo, upon arrival in U.S. custody in 2024. Figures like him operated within a system designed to sustain continuity across generations.
Serafin Zambada-Ortiz, son of Ismael “El Mayo” Zambada, following his arrest in Nogales, Arizona. His role reflected how influence extended through family and trusted associates within the broader network. He served approximately five years in prison on drug trafficking charges and is now a free man.
