Amerigo Dumini (August 27, 1894 – December 25, 1967) was an American-born Italian fascist activist who led the group responsible for the 1924 assassination of United Socialist Party leader Giacomo Matteotti.
Born in St. Louis, the son of Italian immigrants to the United States, Amerigo Dumini traveled to the family's ancestral region, Florence, at the end of the First World War and became active in the local fascio organized by partisans of Benito Mussolini, taking pride in being referred to as "sicario del Duce" ("Il Duce's hitman"). He participated in the Sarzana incident on 21 July 1921, leading a column of 600 "squadristi" (Blackshirts) to Sarzana with demands for the liberation of Renato Ricci. Ricci and other fascists had been arrested following armed confrontation with the Arditi del Popolo, an antifascist organization created in 1921 by the anarchist Argo Secondari as an offshoot of the "Arditi" movement.
In 1924 Dumini entered the ranks of Ceka, the secret police which Mussolini based on the Soviet Cheka. Shortly thereafter, on June 24, he headed the group that carried out the killing of Giacomo Matteotti, possibly on the orders of Cesare Rossi, to whom he was assistant at the time. Following the political murder, he was abandoned by the Fascist leadership, with the exception of Roberto Farinacci, who defended him during his trial. While Farinacci declared himself "honored" by the task, he could not prevent Dumini from receiving a five-year prison sentence, of which he only served eleven months, benefitting from an amnesty ordered by Mussolini.
Once out of jail, he tried his hand at blackmailing the fascist leadership, trying to obtain rewards and the payment of his legal fees. Ostentatiously, he sought a meeting with Mussolini at the Italian Council of Ministers. He justified his entitlement with the words "I am here in order to wash Matteotti's blood off my hands". Arrested, he was put on trial for "offending Il Duce" and sentenced to eight years in prison—substantially more than for the previous crime.
Freed in 1927, Amerigo Dumini left for Italian Somaliland, having been awarded a large state pension (5,000 lire). Apparently, he was still viewed as troublesome, since he was detained and interned on the Tremiti Islands. Meanwhile, he warned General Emilio De Bono that he had filed a manuscript detailing Matteotti's murder with notaries in Texas. This claim led to his release and an increase in pension to as much as 50,000 lire. He left for the Italian colony of Libya, where his pension was further increased by 2,500 lire (together with a single payment of 125,000 lire).
He remained in the region for more than a decade and was captured by the British Army during the North African Campaign of World War II. Sentenced to death as a spy, he was hit by seventeen bullets and still managed to remain alive, escaping to safety in Tunisia during the night.
As Dumini returned to Italy, he was received with astonishment and offered yet another generous pension. He went into business as a transporter and bought a villa in a residential area of Florence.
With the 1943 fall of Fascism in southern in Italy, he joined the German-backed Italian Social Republic. After the liberation of that region, Dumini was arrested in Bologna and placed on trial for Matteotti's murder. He was given a life sentence, but spent no more than eight years in prison and, following more than a decade in quiet retirement, died at the age of 73 as the result of a domestic accident.
