CJNG Fragmentation Risk Accelerating — Janes, InSight Crime, Wilson Center All Warn of Intra-Cartel War

Multiple independent security analysis organizations are warning that CJNG fragmentation is accelerating following El Mencho's death. Janes Intelligence assessed that El Mencho's death 'will very likely exacerbate violence in several Mexican states in the long term,' with increased clashes in Nayarit, Jalisco, Zacatecas, Michoacán, and Guerrero in the short term (1–6 months). InSight Crime highlighted that CJNG has no clearly defined single successor who can guarantee organizational cohesion, and that powerful commanders with geographically separate factions — particularly El Jardinero — control their own corridors and 'do not necessarily need to maintain cooperation for their faction's survival.' The Wilson Center and New Lines Institute both warned that El Doble R's arrest eliminates the most credible non-family succession candidate, creating a two-way split between O3 (family claim + paramilitary force) and El Jardinero (regional power + operational experience). The Colima state, where CJNG's control of the Port of Manzanillo is its most economically critical asset, is expected to see increased violence as competing factions and external rivals probe for weaknesses. Some analysts warn Mexico's national homicide rate decline of 2021–2025 could sharply reverse in 2026.
