Mexican security forces have killed Nemesio “El Mencho” Oseguera Cervantes, the most-wanted leader of the Jalisco New Generation Cartel, in a high-stakes operation on Sunday, sparking retaliatory violence and chaos across several regions.
Operation details
El Mencho, one of Mexico’s most notorious drug traffickers, oversaw the cartel’s distribution of methamphetamine and fentanyl into the United States. The operation, carried out by Mexican Special Forces and the National Guard’s Special Immediate Reaction Force, followed a tip received on February 20 about the cartel leader’s location in a cabin complex on the outskirts of Tapalpa, Jalisco.
Authorities relied on intelligence linked to a romantic partner of Oseguera to locate him. Ground forces established a perimeter, engaged cartel lieutenants, and tracked Oseguera into a nearby wooded area. After an exchange of fire, Oseguera and two bodyguards were captured but severely wounded. They, along with a soldier, were evacuated via helicopter but died en route to hospital treatment.
Eight cartel members were killed in the operation, while two soldiers were wounded. The assault triggered immediate chaos, including road blockades, shootouts, and the suspension of airline operations in affected regions. Reports indicate 25 National Guard military police personnel were killed during subsequent unrest.
Context and significance
President Claudia Sheinbaum, under pressure from US President Donald Trump to crack down on drug trafficking, coordinated the operation while also weighing the impact on tourism and public safety ahead of the 2026 FIFA World Cup, with Guadalajara hosting four group-stage matches.
Security experts note that while the operation removes a symbolic leader, the Jalisco cartel remains largely intact due to its franchise-style structure, allowing local bosses to operate autonomously. Analysts warn of potential short-term violence as factions react to Oseguera’s death, but they do not foresee the cartel fracturing entirely.
Wider implications
El Mencho’s death has strategic, political, and economic implications for Mexico. Analysts suggest the move signals the government’s willingness to act decisively against drug trafficking while managing international scrutiny, particularly from the United States.
David Mora of the International Crisis Group stated that while the Jalisco cartel may face internal instability, rival cartels could attempt to expand their influence, increasing the risk of regional conflict. The operation highlights the ongoing challenges of combating organized crime in Mexico, balancing security, public perception, and international relations.
