Mexican Police Kill Zetas Cartel Lieutenant Mexican police say they have killed a leader of the hyper-violent Zetas drug cartel in the border state of Tamaulipas during a gun battle in the neighboring state of Veracruz. Federal police say suspect Enrique Delgado Fraire and one of his bodyguards were killed in the shootout with police, and eight others were arrested. Police say Delgado Fraire helped break 53 inmates out of jail in the northern state of Zacatecas in 2009. In that incident, a convoy of gunmen drove into the prison and sprang their colleagues, as guards stood by. Police said Friday that Delgado Fraire was a former policeman and headed Zetas operations in southern Tamaulipas. Police seized guns and grenades following the Thursday confrontation.
