Escalating Violence in Sinaloa

The discovery of twenty bodies near Culiacán, including five decapitated victims hanging from a bridge, highlights the brutal cartel war ravaging Mexico's Sinaloa state. This violence stems from a power vacuum created after the 2024 arrest of Sinaloa Cartel co-founder Ivan 'El Mayo' Zambada and Joaquín Guzmán (son of 'El Chapo').

Internal Power Struggle

Following Zambada's extradition to the US, a violent conflict erupted between Zambada's faction and the remaining Guzmán family faction ('Los Chapitos'). Over 3,000 people have been killed or disappeared in Sinaloa since mid-2024, including nearly 50 children. June 2025 became the deadliest month with 200 murders and 80 disappearances despite Mexican military deployment.

Economic Devastation

The conflict has crippled Sinaloa's economy: hundreds of restaurants closed, shopping districts abandoned, and regional GDP contracted by 3%. Between September 2024-April 2025, Culiacán alone lost 14,000 jobs according to InsightCrime. The Sinaloa Cartel, Mexico's dominant fentanyl producer, now faces internal fragmentation affecting its global operations.

New Criminal Alliance

Weakened by infighting, Los Chapitos have formed a strategic alliance with their former rivals, the Jalisco New Generation Cartel (CJNG). This partnership provides CJNG access to Sinaloa's international trafficking networks across Europe, Asia, and Australia. US intelligence warns this could disrupt Mexico's criminal balance and increase drug flows northward.

Global Implications

The CJNG, designated a terrorist organization by the US in 2025, may become "the world's largest drug trafficker" through this alliance. With the US as primary market, Republican politicians advocate military intervention in Mexico. President Trump and Defense Secretary Hegseth have hinted at operations targeting cartel leadership should violence escalate further.
