Escalating cartel clashes push violence into Mazatlán and southern Sinaloa

In early August, Mazatlán and surrounding towns in southern Sinaloa saw a surge of cartel-related killings, injuries and drone attacks, while authorities claim a recent high-profile killing has eased fighting in Culiacán.

Mazatlán, Sinaloa’s premier tourist hub, is confronting a wave of cartel violence that officials say intensified after the killing of Cristhian Guadalupe Pérez Pérez, alias “El Texas,” an operation that security officials expect will reduce homicides in Culiacán. In the first week of August, authorities logged as many as 32 violent events, resulting in 14 confirmed murders—mostly men—and eight injuries, including three state police officers targeted by drones on the Mazatlán-Culiacán bypass near El Chilillo.

Residents of the Concordia highlands warned relatives to avoid the mountains, describing armed men patrolling towns and drone strikes that have forced many to flee. In San Ignacio, locals note a shift in control to the La Mayiza faction, citing a leader named René Bastida who allegedly negotiated a cease-fire. The city’s security forces have deployed over 6,000 troops to protect the tourist zone, yet bodies continue to be discovered in working-class neighborhoods, highlighting the uneven reach of the military presence.
