Municipal and traffic police in the area of San Fernando, Tamaulipas, are involved in the 2010 massacre of 72 migrants, according to information provided by the Office of the Attorney General, according to a non-governmental, non-profit research and archival institution located from Washington, D.C.

The report by the National Security Archive, says that the Mexican authorities responded to a demand presented before the Federal Information Access Institute to request data on the migrant massacre.

The documents include declarations by members of the Zetas drug cartel, who said that the municipal police acted as watchers for them, intercepted people and gave a blind eye to their criminal activities.

The report says that Álvaro Alba Terrazas, one of the detainees, informed to the PGR that the Zetas paid the police to have all detainees sent to them instead of jail.

“I know that the police and transit officers from San Fernando help the Zetas organization, because instead of taking detainees to the Pentagon, the municipal jail, they take them to the Zetas. The head was an old policeman, and another one named Oscar Jaramillo, who receive money from the organization for their collaboration”, according to the document.

The Federal Police arrested 16 members of the municipal police in San Fernando on April 13 2011 for those crimes, and they were given formal prison on June 30, 2011.

The National Security Archive compared this massacre with the disappearance of the 43 students from Ayotzinapa in the municipality of Iguala, Guerrero, because, according to the institution founded in 19850 to check rising government secrecy, it repeats the same patterns.

“Just like the Ayotzinapa case, the massacre of San Fernando is symptomatic of a dirty war of corruption and narco-politics, which has consumed areas of Mexico during the last decade,” it says.
