Full story

Multiple sources reported on Sunday the Mexican government killed the country’s most wanted cartel boss, Nemesio Rubén Oseguera Cervantes, or “El Mencho,” during a military operation in Jalisco.

“El Mencho” led the Jalisco New Generation Cartel (CJNG). Last February, the U.S. State Department listed the cartel as a terrorist organization. The New York Times reported security forces killed him in Tapalpa, where the cartel is based.

According to the State Department, CJNG was formed in 2009 and has been assessed to have the highest cocaine, heroin and methamphetamine trafficking capacity in Mexico. Over the past few years, that’s included the trafficking of fentanyl into the United States.

The State Department said under Oseguera Cervantes’ leadership, CJNG has been responsible for many homicides against rival trafficking groups and Mexican law enforcement officers. More recently, CJNG operatives, allegedly under Oseguera Cervantes’ direction, were involved in assassination attempts of Mexican government officials.

Jalisco Gov. Pablo Lemus Navarro confirmed an operation was carried out.

“As a result of said operation, in various points of that region and in other parts of Jalisco, individuals have burned and blocked vehicles with the aim of hindering the actions of the authorities,” Navarro said.

A code red has been issued in the state, and major events as well as in-person classes were canceled.

The U.S. Embassy is telling Americans in Jalisco State (including Puerto Vallarta, Chapala and Guadalajara), Tamaulipas State (including Reynosa and other municipalities), areas of Michoacan State, Guerrero State and Nuevo Leon State, that they should shelter in place. The U.S. State Department has a $15 million reward for “El Mencho’s” arrest or capture.

Air Canada said on X it is temporarily suspending operations in Puerto Vallarta as the situation plays out.
