Details of the internal investigation of the Civil Guard around the Barracks case reveal the lack of control of the management of Fernando Grande-Marlaska in the Ministry of the Interior. In 2016 Lieutenant General Pedro Vázquez Jarava – the alleged director of the network – gave businessman Ángel Ramón Tejera de León, alias Mon, 80 contracts worth 1.3 million.
Most of these works "were not executed or were poorly executed," according to the Internal Affairs Service of the Armed Institute.
