El Mencho Killed: Violence Erupts Across Mexico After Cartel Leader’s Death

Mexico is grappling with widespread violence following the death of Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG). The operation to capture and the subsequent fallout have resulted in at least 73 fatalities, including 25 members of Mexico’s National Guard, and sparked unrest in over 20 states.

Who Was El Mencho?

Nemesio Rubén Oseguera Cervantes (1966-2026) was a Mexican drug lord and the head of the CJNG, an organized crime group based in Jalisco. He was considered the most wanted person in Mexico and one of the most sought-after by the United States. Both governments had offered substantial rewards for information leading to his arrest – up to US$15 million from the U.S. And MXN$300 million from Mexico’s Office of the Attorney General [1].

How Did El Mencho Die?

El Mencho died on February 22, 2026, after succumbing to gunshot wounds sustained during a military operation conducted by the Mexican Armed Forces in Tapalpa, Jalisco [1]. The operation, aided by U.S. Intelligence support, initially targeted El Mencho and resulted in the deaths of eight other cartel members [2]. He was seriously injured in a firefight between his bodyguards and the military commandos deployed to capture him.

The Aftermath: A Wave of Violence

The death of El Mencho triggered a wave of violence across Mexico. Suspected gang members responded by torching buses and businesses and clashing with security forces [2]. At least 25 members of the National Guard were killed in attacks in the state of Jalisco [3]. In addition to the National Guard casualties, a prison guard, a member of the state prosecutor’s office, and 30 members of El Mencho’s criminal organization were also killed in the unrest [4].

Impact on Travel and Security

The unrest has disrupted travel in Mexico. The U.S. State Department has urged American nationals in parts of Mexico to “seek shelter and remain in residences or hotels” and established a 24/7 crisis hotline for impacted citizens [2]. Several U.S. Carriers suspended flights to Puerto Vallarta due to the security situation.

Government Response

Mexican President Claudia Sheinbaum has stated that “peace, security and normalcy” are being maintained across the country and praised the army’s operation [3]. Mexico has deployed 2,500 soldiers to the west of the country to bolster security [3].
