El Mencho Reportedly Killed, Violence Erupts Across Multiple Mexican States

Nemesio Oseguera Cervantes — better known as El Mencho — has died after being injured during a military operation in western Mexico, the country’s defence ministry confirmed on Sunday.

According to officials, the fugitive cartel leader sustained serious injuries during a raid in the state of Jalisco and later died while being airlifted to Mexico City for treatment.

El Mencho was the head of the powerful Jalisco New Generation Cartel (CJNG), which over the past decade grew into one of Mexico’s most dominant criminal syndicates and a major supplier of illicit drugs to the United States.

Violence spreads across multiple states

News of his death was followed by coordinated outbreaks of violence in several regions. Authorities reported burning vehicles, armed roadblocks and highway blockades in more than half a dozen states, including Jalisco.

In Guadalajara, vehicles were set ablaze to obstruct major roads, while videos circulating online showed smoke rising over the tourist hub of Puerto Vallarta. Panic scenes were also reported at local transport hubs.

Jalisco Governor Pablo Lemus Navarro urged residents to remain indoors until security forces regained control.

President Claudia Sheinbaum stated that federal and state authorities were working in “absolute coordination” to contain the unrest.

A major target for the United States

El Mencho had long been one of the world’s most wanted drug traffickers. The United States had placed a $15 million reward on him, accusing him of orchestrating large-scale shipments of cocaine, methamphetamine and fentanyl into North America.

CJNG was designated a foreign terrorist organisation by the administration of Donald Trump last year as part of Washington’s intensified crackdown on transnational drug networks.

US Deputy Secretary of State Christopher Landau described the operation as a significant development for regional security.

Following the unrest, the US State Department issued security alerts for American citizens in multiple Mexican states, including Jalisco, Tamaulipas, Michoacán, Guerrero and Nuevo León. Canada also advised its citizens in Puerto Vallarta to shelter in place.

CJNG’s rise under El Mencho

Under Oseguera’s leadership, CJNG evolved from a regional offshoot into a highly organised transnational network known for military-style tactics, heavy weaponry and aggressive territorial expansion.

Although historically overshadowed internationally by the Sinaloa Cartel once led by Joaquin Guzman, CJNG became synonymous within Mexico with rapid growth and violent enforcement methods.

Authorities now face concerns over potential power struggles within the organisation and further retaliatory violence in the aftermath of El Mencho’s death.
