Inside the War for Southern Sinaloa: What the Cabreras Really See

From inside Durango’s mountains, when you ask the Cabreras how they read the battlefield in southern Sinaloa, they don’t pull out an org chart — they point to the people shooting at them. And from their perspective, the Chapiza structure moving against them lines up like this:

At the very top sits Iván Archivaldo Guzmán, the strategic center of gravity for the entire Chapiza machine.

But on the ground — in the dirt roads of Concordia, the humid edges of Escuinapa, the twisting hills of Matatán, and the harsh Sierra routes that lead toward Mazatlán and Guadalupe de los Reyes — the Cabreras say the real fight has been carried by a specific group of Chapiza operators:

• René “00” 

• Gabito “80” 

• Kasko “81” 

• El Güero Pin 

• El 40 de Mazatlán 

• El Benny 17 

These are the names the Cabreras bring up every time. These are the operators who have pushed, advanced, retreated, regrouped, and returned — the ones who’ve actually been showing up to fight since the first shots of this Sinaloa war were fired.

And, as they point out, others who once fought in those same mountains didn’t stay loyal. Los Ratones, Bitache, and Koyote all fought the Cabreras early in the conflict — until they flipped and crossed over to the Isidros.

Then there’s G3. He began the war wearing Chapiza colors, but walked away, crossed the line, and aligned himself directly under the Cabreras in Tamazula, Durango. And if you want to understand how fluid this conflict is, start there: in a war where even the commanders shift sides mid-campaign.

Because what the Cabreras describe — and what sources across Sinaloa echo — is a conflict defined as much by betrayals as by gunfire. And not just betrayals from Chapiza elements. The MFs have torn at their own alliances, switched loyalties, broken pacts, and played both sides when it suited them.

This is not the old Sinaloa of fixed loyalties and predictable lines.

This is a landscape where:

• Men who grew up together now hunt each other.

• Groups that once shared safehouses now exchange fire.

• And alliances form between cartels no one ever expected to see in the same room.

Every week, someone flips.

Every month, a new column of trucks appears with a different set of initials painted on the doors.

And every day, the lines between Chapiza, Mayiza, Cabrera, and Isidro blur a little more.

What’s unfolding in southern Sinaloa is no longer a territorial clash — it’s a reconfiguration of the entire Pacific drug war. And for the Cabreras, the war is not abstract. It’s personal, local, and centered on the men who show up with rifles in their hands.

In a conflict full of shifting loyalties and impossible alliances, one thing remains absolutely clear:

nothing in Sinaloa is stable, and the next betrayal is always closer than it looks.
