In 1834, Quiroga was appointed by the governor of Buenos Aires (and Representative of Foreign Relations of the
Argentine Confederation)
Manuel Vicente Maza to mediate between the governors of
Tucumán and
Salta, but Salta governor De la Torre died before Quiroga could arrive. He was advised that there were plans to murder him on his way back, but Quiroga, disregarding the advice, returned to Buenos Aires through the same way. At
Barranca Yaco, a watering place between Córdoba and
Santiago del Estero, a party of gunmen ambushed the carriage in which he travelled. Quiroga, confident in his charisma and that his mere presence and resolution would discourage the attackers, appeared through the carriage door and shouted at the gunmen, asking for their commander to confront him. The leader of the party, Santos Pérez, however, did not take chances and killed Quiroga by shooting him through the left eye. The political crime created a huge crisis in all the Confederation, forcing Maza to resign, and led to the establishment of Rosas' government. Rosas, as the Confederation leader, led the criminal investigation that ended with the prosecution of the governor of Córdoba,
José Vicente Reinafé, and his brother as the intellectual perpetrators of the crime. They were hanged along with Santos Pérez in 1837 in Buenos Aires. After Facundo's death, the execution of his will revealed that he never seized nor inherited any wealth or property from his father. Instead, Ariel De La Fuente states in his 2000 book,
Children of Facundo, that he: "accumulated his fortune during eighteen years of married life, a period that coincides, almost exactly, with his entire political career (1818-1835).". In addition, Facundo's family would inherit his properties in Buenos Aires, and all in all, his fortune would total to be around 200,000 pesos. This mass sum is attributed almost entirely as a result of his political career and not from his lifestyle as a caudillo rancher. In 1845,
Domingo F. Sarmiento wrote
Facundo, Civilization and Barbarism, a book that reviews the influence of
caudillo leaders, which he defines as "
barbarism", in the Argentine political and social life, but also as a protest to Rosas' regime, and a call for
European education and life style. Sarmiento’s
Facundo was also expanded upon in a book titled
Children of Facundo: Caudillo and Gaucho Insurgency During the Argentine State-Formation Process (La Rioja, 1853-1870), written by Ariel de la Fuente. De la Fuente argues that the struggles in La Rioja encompassed more than the upper-class divisions between Unitarian and Federalist, and he suggests viewing the conflicts from the perspective of the lower-class gauchos to see these differences.
Children of Facundo further depicts Facundo as a complex leader. His relationship with the gauchos was presented as a double-edged sword, where the gauchos are responsible for the caudillo's notoriety, and the caudillo (Facundo) is responsible for the gauchos' supply of necessities. Quiroga is buried in
La Recoleta Cemetery in
