The Mexican federal government issued a statement on 13 May 2012 condemning the attacks . The Secretaría de Gobernación ( Segob ) offered its support to aid the authorities of the state of Nuevo León to find those responsible . The municipal authorities of the state were also asked to maintain coordination and work in unison with the Federal government . The Mexican authorities then asked the population to stay calm , since the massacre took place in a remote area and in the darkness of the early morning . In addition , SEGOB emphasised that as for the Monterrey casino attack and the San Fernando massacre , justice would be served
