The gunmen are believed to belong to the Zetas drug cartel, said Alejandro Poire, the Mexican government's national-security spokesman. Earlier Wednesday, officials said they had found the bodies of a Tamaulipas prosecutor and police chief who had gone missing shortly after beginning an investigation into the massacre. The discovery of the bodies of Roberto Suarez, a state detective, and Juan Carlos Suarez Sanchez, a local police chief, sent a chilling message to authorities investigating the work of organized crime in Mexico's troubled north. The two men had been assigned to solve the mass killing of 72 immigrants-58 men and 14 women-from Central and South America who had apparently been on their way to the U.S. The immigrants' bodies were found on Aug. 25. Tamaulipas, which borders Texas, is caught in a violent turf war between two former cartel allies turned enemies, the Gulf Cartel and its former enforcers, the Zetas. The violence was on display again on Wednesday. Officials said a shootout between police and gunmen linked to a cartel left five people dead, and closed down the road between the state capital of Ciudad Victoria and the Mexican border city of Matamoros, just across from Brownsville, Texas. Gunmen in the state of San Luis Potosi, just south of Tamaulipas, shot and killed the mayor of the town of El Naranjo as he was sitting at his desk. It was the latest in a string of killings of Mexican mayors, all believed to have been carried out by cartels. The Committee to Protect Journalists, a New York-based advocacy group, issued a report Wednesday saying more than 30 journalists have gone missing or been killed since 2006 and criticizing the Mexican government's response to the attacks. As a result, the report said, news related to drug trafficking hasn't been reported in many areas. - --- MAP posted-by: Jo-D
