What Happened
Guadalupe Moreno Carrillo has emerged as a pivotal figure in a significant law enforcement operation that led to the death of Nemesio Oseguera Cervantes, known as “El Mencho,” the leader of the Cártel Jalisco Nueva Generación (CJNG). Her visit to El Mencho just days before his death on February 22, 2026, provided crucial intelligence that enabled Mexican and U.S. forces to locate and confront the cartel kingpin.
Why It Matters
The operation against El Mencho, confirmed by Mexican Defense Secretary Ricardo Trevilla Trejo, highlights the importance of intelligence-sharing between nations in combating organized crime. Following El Mencho’s death, violent disturbances erupted across Mexico, resulting in the deaths of 25 National Guard members and three civilians. The unrest raises significant concerns regarding public safety and the stability of the region.
What’s Next
In the aftermath of El Mencho’s death, authorities are focusing on the remaining members of the CJNG and their operations. The killing of key lieutenant Hugo César Macías Ureña, alias “El Tuli,” during a confrontation with security forces underscores the ongoing violence associated with the cartel. The situation remains fluid, with potential implications for bilateral security cooperation and humanitarian issues in the region.
