The mutilated bodies of 11 people were found Wednesday near this metropolis in western Mexico, authorities said.

Official sources told Efe the victims were left in two pickup trucks abandoned near a motel on the road linking Guadalajara with the town of Chapala.

Police went to the scene after receiving an anonymous telephone call from a woman who spotted the bodies.

All of the victims were mutilated and three of them had been decapitated, according to the sources, who said the remains were taken to the Jalisco state medical examiner's office for identification.

The killings bear the hallmarks of organized crime.

The bodies of 26 people were discovered last Nov. 24 inside three vehicles abandoned on a main thoroughfare in Guadalajara, Mexico's second-largest city.

Authorities subsequently attributed that slaughter to the Los Zetas drug cartel.

The Zetas, a band of special forces deserters turned outlaws, have been locked in a turf war in Jalisco with Joaquin "El Chapo" (Shorty) Guzman's Sinaloa drug cartel, which operates there via an ally, the Jalisco Nueva Generacion mob.

Conflict among rival drug cartels and between criminals and the security forces has claimed more than 50,000 lives in Mexico since December 2006, when newly inaugurated President Felipe Calderon militarized the struggle against organized crime.
