In a shocking incident, the residents of Zacatecas, Mexico, witnessed a dog carrying a decapitated human head in its mouth and running down a dark street at night.
Authorities say the massacre of 20 townspeople in southern Mexico was probably the work of a drug lord who used social media to try to blame a rival gang.
