Rival Criminal Organizations Intensify Pressure on CJNG Across Michoacán and Guanajuato

Ongoing conflict tracking by InSight Crime and ACLED documents continued intensification of violence in Michoacán and Guanajuato as rival criminal organizations test CJNG's weakened post-Mencho cohesion. Carteles Unidos continues operations to drive CJNG out of Michoacán strongholds, while the Santa Rosa de Lima Cartel is pressing in Guanajuato. Security experts warn that CJNG's El Menchito (Rubén Oseguera González) — sentenced to life in prison plus 30 years by a U.S. federal court in March 2025 — is unable to provide leadership from his U.S. prison cell, leaving regional commanders with no clear chain of command. Authorities in Michoacán reported ongoing armed confrontations in multiple municipalities, while Guanajuato remains Mexico's most violent state by homicide count. The International Crisis Group's David Mora noted that CJNG's territorial defense will depend on whether 'El 03' can rapidly consolidate loyalty among disparate regional plaza bosses.
