Giuseppe Pinelli

Calabresi was later killed by two shots from a revolver outside his home in 1972. In 1988, former Lotta Continua leader Adriano Sofri was arrested with Ovidio Bompressi and Giorgio Pietrostefani for Calabresi's murder. The charges against them were based on testimony provided, 16 years later, by Leonardo Marino, an ex-militant who confessed to the murder of Calabresi, under order from Adriano Sofri. Claiming his innocence, Sofri was finally convicted after a highly contentious trial, in 1997.

On 12 December 1969, a bomb went off at the Piazza Fontana in Milan that killed 17 people and injured 88. Pinelli was picked up, along with other anarchists, for questioning regarding the attack. Just before midnight on 15 December 1969, Pinelli was seen to fall to his death from a fourth floor window of the Milan police station. Three police officers interrogating Pinelli, including Commissioner Luigi Calabresi, were put under investigation in 1971 for his death, but legal proceedings concluded it was due to accidental causes.

Pinelli's name has since been cleared, and the far-right Ordine Nuovo was accused of the 1969 Piazza Fontana bombing (in 2001, three neo-fascists were convicted, a sentence overturned in March 2004; a fourth defendant, Carlo Digilio, was a suspected CIA informant who became a witness for the state and received immunity from prosecution).

During the 1960s, he continued anarchist activism. He organized young anarchists in the Gioventù Libertaria (Libertarian Youth) in 1962. He helped found the "Sacco and Vanzetti anarchist association" in 1965. He founded the Ponte della Ghisolfa association (named after the nearby bridge) in 1968.

In 1954, he found work as a railroad fitter. In 1955, he married Licia Rognini, whom he had met at an evening class of Esperanto.

Giuseppe "Pino" Pinelli (21 October 1928 – 15 December 1969) was an Italian railroad worker and anarchist, who died while being detained by Italian police in 1969. Pinelli was a member of the Milan-based anarchist association named Ponte della Ghisolfa. He was also the secretary of the Italian branch of the Anarchist Black Cross. His death, believed by many to have been caused by members of the police, inspired Nobel Prize laureate Dario Fo to write his famous play titled Accidental Death of an Anarchist.
