Mexico’s most wanted man and leader of the Jalisco New Generation Cartel (CJNG), Nemesio Oseguera Cervantes, popularly known as “El Mencho”, was recently killed during a military operation aimed at arresting him.
El Mencho led the CJNG, which became one of Mexico’s most powerful criminal groups under his leadership, expanding its operations across several states and internationally.
