A senior federal police official was gunned down Saturday while driving his car in the northern city of Saltillo and was in critical condition, police said. Jose Luis Hernandez Marquez, chief of Mexico's Federal Preventative Police force in the border state of Coahuila, was shot at least five times Saturday morning by gunmen traveling in two vehicles, said a spokesman for the force, who declined to be named because he was not authorized to comment on the case. The police chief's car "was intercepted by two vehicles from which various people, who have yet to be identified, opened fire on him," the federal attorney general's office said in a statement.
