Mexican Navy Dismantles Chapitos-Linked Meth Lab in Cosalá — 1,000 Liters of P2P Precursor Seized

Mexican Navy (SEMAR) forces coordinating with the FGR raided and dismantled a clandestine methamphetamine laboratory in La Palma, Cosalá municipality on April 3, 2026. The lab was identified as Chapitos-linked. Seized materials included 1,000 liters of phenylacetone (P2P, a primary methamphetamine precursor), 44 liters of toluene, and 100 kilograms of caustic soda. No armed confrontation was reported during the operation. Cosalá is a central Sinaloa municipality contested throughout the cartel civil war, with multiple factions operating in the rugged terrain. The seizure follows the March 19 Navy capture of La Mayiza plaza boss El Patas, underscoring SEMAR's expanded intelligence-driven operational tempo in Sinaloa.
