Top cartel figure El Mencho died after a clash with Mexican army forces, triggering widespread violence across multiple states
Nemesio Oseguera Cervantes, widely known as El Mencho, was one of the world’s most feared drug traffickers and the long‑time leader of Mexico’s powerful Jalisco New Generation Cartel (CJNG). Mexico’s defence ministry said the 59‑year‑old cartel boss died after being seriously wounded during a military operation in Tapalpa, Jalisco, and later succumbing to his injuries while being moved toward Mexico City.
The government said special forces executed a well‑planned raid that left four CJNG members dead and three soldiers wounded. Armoured vehicles, heavy weapons and rocket launchers were seized, and Mexican Air Force and National Guard aircraft supported the mission. U.S. authorities provided intelligence that aided the operation.
El Mencho transformed CJNG from a regional gang into one of the most violent and profitable criminal groups in the world, trafficking cocaine, methamphetamine and fentanyl into the United States. The U.S. had offered a $15 million reward for information leading to his capture.
News of his death sparked coordinated retaliatory attacks by cartel gunmen across at least eight states, prompting “code red” alerts and travel disruptions in areas including Guadalajara and Puerto Vallarta. Mexican President Claudia Sheinbaum called for calm as authorities prepared for potential further violence.
