El Mayo Zambada Arrested in Texas — Sinaloa Cartel Civil War Erupts

Ismael 'El Mayo' Zambada, co-founder and leader of the Sinaloa Cartel, is arrested in El Paso, Texas after being lured onto a plane by Joaquín Guzmán López (son of El Chapo, 'El Chapito'). El Mayo claims he was kidnapped; the Chapitos faction denies it. The incident fractures the Sinaloa Cartel into two warring factions — Los Chapitos vs. Los Mayos — triggering catastrophic violence in Culiacán that kills hundreds and displaces tens of thousands.
