The mayor of El Naranjo, Mexico, in the central state of San Luis Potosi was gunned down and killed inside his office

Witnesses say that four armed and hooded men stepped out of a white truck at city hall, the San Luis Potosi government said in a statement. Two of the men posted themselves outside, and two went inside and to the top floor of the building, where they entered the mayor's office and shot him. At least seven mayors in various Mexican states have been assassinated in 2010. Mexican President Felipe Calderon condemned the criminal and cowardly killing of the mayor. Alexander Lopez Garcia assumed office in October 2009 as a candidate for an alliance between the Revolutionary Institutional Party (PRI), and the Ecologist Green Party.
