Mexican special forces killed Nemesio Oseguera Cervantes, known as ‘El Mencho’, the leader of the Jalisco New Generation Cartel (CJNG), in an operation announced by the Secretariat of National Defense on Friday.
El Mencho, who has led the CJNG since 2010, was targeted after the cartel expanded its influence across multiple states and became one of the most violent criminal organizations in Mexico.
What the Right Is Saying
Conservative politicians in Mexico, such as PAN senator José Antonio Meade, praised the operation as a decisive step toward dismantling a major criminal network, arguing that strong security actions are necessary to restore order.
U.S. Republican lawmakers, including Rep. Jim Jordan, referenced the killing as evidence that increased cooperation between U.S. and Mexican security forces can help curb drug trafficking and border-related crime.
What the Left Is Saying
Human rights groups, including Amnesty International, said the operation raised concerns about the use of lethal force and called for an independent investigation, noting that civilian casualties were reported in the towns of Jalisco and Michoacán following the raid.
Mexico's left-leaning Party of the Democratic Revolution (PRD) representative María del Carmen García urged the government to prioritize community development and policing reforms to address the root causes of cartel violence.
What the Numbers Show
According to Mexico’s National Institute of Statistics and Geography (INEGI), CJNG-related homicides rose by 12% in 2025, with an estimated 8,300 deaths attributed to the cartel that year.
The SEDENA press release reported that the operation resulted in the death of El Mencho and three of his top lieutenants, while authorities seized 15 firearms and 20 kilograms of methamphetamine.
Local police records from Jalisco indicate that within 24 hours of the raid, at least 27 incidents of armed confrontations were logged, suggesting a spike in violence as rival groups contest territorial control.
The Bottom Line
The elimination of El Mencho marks a significant blow to the CJNG hierarchy, but the immediate surge in clashes underscores the potential for short‑term instability as factions vie for power, making continued monitoring of security developments essential for both Mexico and its international partners.
