Nemesio Oseguera Cervantes, known as "El Mencho" and the leader of the powerful Cartel Jalisco Nueva Generación (CJNG), was killed on Sunday, February 22, 2026, during a military operation in Mexico. El Mencho had become the country's most formidable criminal figure following the downfall of "El Chapo" of the Sinaloa cartel. The FBI had a substantial bounty of $15 million for his capture, and the U.S. government had designated the CJNG as a terrorist organization, with El Mencho facing charges for racketeering and drug trafficking. His death triggered a tense situation across several Mexican cities, including Puerto Vallarta and Guadalajara in Jalisco, and Michoacán, where vehicles were set ablaze and roads blocked to impede authorities, prompting the governor of Jalisco to advise residents to stay home.
