The prosecutor's office of the state says the four men were shot before they were abandoned along a highway near Creel, a town known as the heart of Tarahumara indigenous group. Police found the bodies on Monday, two days after eight bodies were found also tortured and shot in another part of the state.
Officials also say four men and a woman were shot dead at a convenience store in Chihuahua state's capital, of the same name.
The victims were flower vendors, authorities said Monday.
