Three severed heads were found Tuesday stuffed inside a cooler outside the Guadalupe town hall and 10 more people were killed elsewhere in Mexico's Chihuahua state that sees most of the country's brutal drug violence, police said.
The three beheadings follow that of the Praxedis police chief, whose head was also deposited outside that locality's town hall on Monday.
Police said 10 more drug-related killings also took place Tuesday in northern Chihuahua state, bordering the United States, the chief destination of the multi-billion-dollar drug trafficking by Mexican cartels.
