Background
Known as El Mencho, Oseguera Cervantes broke from the Milenio Cartel around 2010 and expanded CJNG into over 27 of Mexico's 31 states, becoming the dominant supplier of methamphetamine and fentanyl to US markets. The DEA placed a $10 million bounty on him, the largest offered for a Mexican cartel leader. He had evaded capture for over a decade before the military operation.
The Mexican military killed Oseguera Cervantes on 22 February 2026, removing the leader who built the CJNG into one of Mexico's two dominant trafficking organisations . Retaliatory violence killed at least 70 people across a dozen states within 48 hours, with buses burned in Guadalajara , prompting Plan Kukulkan's 100,000-troop deployment .
His death did not dismantle CJNG's financial and logistical network; the succession remains unresolved four months before Mexico co-hosts the FIFA World Cup, with Guadalajara's Estadio Akron sitting in the cartel's operational heartland. The retaliatory wave demonstrated that decapitation without dismantlement can accelerate fragmentation and civilian harm.
