'Decapitated, head left on pick-up truck': Mexican mayor murdered 6-days after assuming office

The mayor of Chilpancingo in southern Mexico was murdered just days after taking office. Alejandro Arcos was decapitated, and his head was discovered on a truck. This follows the killing of city government secretary Francisco Tapia. This violence is part of ongoing cartel-related issues in Guerrero state, where violence against politicians is rising.
