Day 676: CJNG Breaks Alliance with Chapitos in Baja California — New War Front; Two Colombian 'Los Rusos' Mayiza Operatives Arrested in Mexicali; El Financiero Consolidates US Court Calendar for Sinaloa Leaders

On Day 676 of the Sinaloa cartel civil war — May 30, 2026 — three concurrent developments mark the ongoing strategic collapse of Los Chapitos' external alliances and enforcement of Mexico's domestic legal process. CJNG BREAKS WITH CHAPITOS IN BAJA CALIFORNIA: El Financiero reported on May 28 (confirmed in May 30 coverage) that CJNG has formally broken its alliance with Los Chapitos in Baja California — Baja California state security forces confirmed the two organizations have entered open conflict over control of Tijuana, Mexicali, and Ensenada. This is the most definitive territorial-level confirmation of the CJNG-Chapitos rupture that analysts have tracked since El Mencho's death in February 2026 and the April 29 arrest of El Jardinero (CJNG's Sinaloa field commander). With El Mencho dead, new CJNG leader El 03 (Juan Carlos Valencia González) focused on internal consolidation, and now CJNG actively contesting Chapitos positions in BC rather than supporting them, Los Chapitos have lost their primary external military patron. BC is a key corridor for Chapitos-linked fentanyl transshipment northward. TWO COLOMBIAN LOS RUSOS OPERATIVES ARRESTED IN MEXICALI: Proceso reported on May 30 that Mexican federal and state forces arrested two Colombian nationals in the Mexicali Valley on May 28–30: Darwin Ferney 'El Zarco' (from Villavicencio) and a second individual identified as Alexander (from Bogotá). Both were linked to 'Los Rusos,' the armed wing of La Mayiza (the Mayos faction) operating in Baja California. Two stolen vehicles with Arizona license plates were seized — a 2017 Jeep Grand Cherokee and a 2019 Subaru. Both Colombians were presented to the FGR. The arrests demonstrate La Mayiza's ongoing expansion of operations beyond Sinaloa state using foreign paramilitaries. US COURT CALENDAR — EL FINANCIERO OVERVIEW (MAY 30): El Financiero published the definitive May 30 overview of upcoming US sentencing proceedings for detained Sinaloa leadership. Confirmed dates: (1) Ismael 'El Mayo' Zambada EDNY sentencing (3rd postponement) — July 20, 2026, Judge Brian Cogan, Brooklyn; defense memo due July 6. (2) Ovidio 'El Ratón' Guzmán López NDIL sentencing — July 27, 2026, Judge Sharon Johnson Coleman, Chicago. (3) Joaquín Guzmán López NDIL sentencing — August 31, 2026, Judge Coleman. (4) Former Sinaloa Security Secretary Gerardo Mérida Sánchez first SDNY court appearance — scheduled for approximately June 1–3, 2026 (Judge Netburn, SDNY Manhattan; Speedy Trial clock paused pending prosecution's scheduling request). These back-to-back summer sentencing dates represent the most consequential legal events for the Sinaloa organization since Mayo's July 2024 capture — each is expected to surface new cooperation intelligence and plea testimony. Overall on Day 676: La Mayiza holds ~90% of former Chapitos territory in Sinaloa; 13,300+ federal troops deployed under interim Governor Bonilla Valverde. El Chinacate held at Altiplano; 60-day US extradition clock (from May 28) has 29 days remaining as of today. Running conflict toll: ~2,425+ homicides (Noroeste) / 3,000+ (WSJ) since September 9, 2024; ~5,800 disappearances (NGO Sabuesos Unidas AC).
