El Mencho Killed: Mexico Deploys 10,000 Troops as CJNG Retaliates Nationwide

Mexico Faces Crisis After El Mencho Is Killed; 10,000 Troops Deployed Nationwide

Mexico is entering one of its most turbulent moments in recent history following the death of Nemesio Rubén Oseguera Cervantes, better known as El Mencho, the leader of the Jalisco New Generation Cartel (CJNG). His death occurred during a major military raid supported by intelligence from the United States. The operation and subsequent retaliation have left more than 70 people dead, disrupted multiple regions, and triggered widespread fear of escalating cartel warfare.

El Mencho, a former police officer and avocado farmer, built the CJNG into what U.S. authorities consider the most powerful and aggressive cartel in Mexico. He managed operations linked to large-scale trafficking of fentanyl, heroin, methamphetamine, and cocaine into the United States.

Authorities located him after tracing the movements of a close associate tied to one of his romantic partners. Once his exact location was confirmed in a rural area of Tapalpa, Jalisco, Mexican forces launched a rapid assault. During the confrontation, cartel gunmen fired high-caliber weapons, even striking a military helicopter and forcing it to make an emergency landing. El Mencho attempted to escape through nearby forested terrain but died from injuries while being transported by air.

CJNG Retaliates With 250 Roadblocks Across 20 States

Within hours of the raid, CJNG cells executed a massive retaliation campaign. More than 250 roadblocks were set up across 20 states, where cartel members burned vehicles, attacked gas stations, and targeted government buildings. A prison in Jalisco was hit during the chaos, allowing 23 inmates to escape.

Authorities identified Hugo César Macías Ureña, also known as El Tuli, as the key commander behind the coordinated violence. He reportedly offered cash rewards for killing soldiers. He was later tracked down and killed during a separate operation.

Military Deployed as Violence Escalates

The unrest has resulted in more than 70 deaths, including military personnel, cartel members, and civilians. Mexico deployed 10,000 federal troops to stabilize the country, with an extra 2,500 soldiers sent as reinforcements to Jalisco.
President Claudia Sheinbaum later announced that all roadblocks had been cleared, stating:
“Mexico is calm. We woke up without any roadblocks.”
Security experts, however, caution that the calm may be temporary.

U.S. Intelligence Assistance Raises Questions

The United States provided substantial intelligence support leading up to the operation. Surveillance aircraft, network monitoring, and interagency collaboration helped pinpoint the cartel leader’s movements. The U.S. previously offered a $15 million reward for information leading to El Mencho’s capture and formally designated the CJNG as a terrorist organization in 2025.

This level of foreign involvement has sparked discussions about sovereignty and the balance of cooperation between both nations.

A Dangerous Power Vacuum Ahead

Despite El Mencho’s death, experts warn that the CJNG’s structure remains strong. The organization may splinter into rival factions, each vying for territory and influence. With no clear successor — and El Mencho’s son imprisoned in the United States — Mexico could face a wave of internal cartel disputes.

Analysts compare the situation to removing the CEO of a major organization while the system beneath continues operating, but now without direction — a scenario that often leads to instability and violence.
