For more than a decade, Nemesio Oseguera Cervantes — known as El Mencho — built the CJNG into one of the world's most powerful drug trafficking organizations, with $50 billion in assets and operations spanning five continents. On February 22, 2026, the Mexican Army killed him during a coordinated raid near Tapalpa, Jalisco, ending a $15 million U.S. bounty manhunt.
Within hours, CJNG operatives launched retaliatory attacks across more than a dozen Mexican states, torching vehicles, blockading highways, and clashing with security forces from Puerto Vallarta to Tamaulipas. Airlines canceled flights to the resort city, Jalisco's governor declared a red alert, and the U.S. Embassy told Americans to shelter in place. The immediate violence shows a recurring pattern in Mexico's drug war: killing a cartel leader removes one threat but often fractures the organization into competing factions — each fighting for territory and revenue with greater brutality.
