Police found the severed heads of two men tossed on a street in front a car dealership in the western Mexico state of Michoacan on Saturday, state prosecutors reported. A sign made of cutout newsprint letters found next to the severed heads said, "Dear Comrades, the Michoacan Family aren't extortionists, PS, I am waiting for your next call." The bodies of the men - one a former federal police officer - were found dumped on the side of a dirt road in Zitacuaro, about 100 kilometers west of Mexico City, prosecutors said. The sign was similar to one left next to five severed heads tossed into a bar in another Michoacan city, Uruapan, on September 6. That sign read: "The family doesn't kill for money. It doesn't kill women. It doesn't kill innocent people, only those who deserve to die."
