Yesterday, just as we were wrapping up—almost on our way out—news broke confirming the arrest in Sonora of Isaí Martínez Cepeda, aka El Chinacate, a nephew of “El Chapo” Guzmán. What was his role within the Sinaloa Cartel? What do we know about his previous arrest? Let’s take a look together.
This is a name that once again carries significant weight on the map of drug trafficking. Yesterday, Security Secretary Omar García Harfuch confirmed the capture of Isaí Martínez Cepeda, aka “El Chinacate”, a direct nephew of Joaquín “El Chapo” Guzmán. The arrest took place during a surprise operation conducted inside a home in the Casablanca neighborhood of Nogales, Sonora.
For the federal government, this 43-year-old man is no ordinary relative; he is a key figure. “El Chinacate” is identified as the logistical operator for the “Chapitos” faction in Sonora, responsible for the production and shipment of synthetic drugs to the United States and Costa Rica.
In fact, intelligence agencies accuse him of trafficking—in 2025 alone—more than 10,000 fentanyl pills across the border into the neighboring country; consequently, he is already subject to an extradition order. His capture stands out because this is not his first time behind bars.
Eighteen years ago—in June 2008, when “El Chapo” and “El Mayo” Zambada were at the helm of the Sinaloa Cartel—Isaí was arrested in Culiacán in possession of an AK-47 rifle and subsequently incarcerated at the Altiplano maximum-security prison.
Furthermore, he is the brother of Enoc N.—alias “El Bocho”—the organization’s longtime financial operator. With the fall of “El Chinacate,” federal authorities have dealt a direct blow to the family and distribution structure of the “Chapitos” along the border. Now, the fate of this veteran operative appears to lie far from the mountains of Sonora—and very close to a maximum-security prison in the United States.
