Rival Sinaloa Cartel factions continue to battle in the Triángulo Dorado area of Guadalupe y Calvo, Chihuahua, and across the state, spurring a 75 % rise in homicides in 2025. The El Guano, Mayito Flaco and newcomer La Línea groups clash over drug routes, mineral sites and forest resources, while broader state violence pits Los Chapitos against La Mayiza after the U.S. transferred cartel leaders in July 2024.

On 4 August 2026, 25‑year‑old TikTok influencer César Gastélum was shot dead while livestreaming outside a KFC in the Tres Ríos district of Culiacán. Two men on a motorcycle approached; one fired a close‑range shot to the head, killing him instantly. The killing was captured on his livestream and nearby security cameras and quickly spread online before removal. Soldiers, police and forensic teams sealed the scene, recovered shell casings and opened a criminal investigation, but no arrests have been reported.

President Claudia Sheinbaum pledged a thorough investigation and vowed to capture the perpetrators. The incident mirrors the May 2025 murder of beauty influencer Valeria Marquez in Jalisco, underscoring the persistent threat to online creators amid ongoing cartel‑related violence and the wider power struggle between rival organized‑crime factions linked to the Sinaloa Cartel and the Jalisco New Generation Cartel.
