On 23 May 1992, a Sicilian Mafia car bomb killed Italian anti-mafia magistrate Giovanni Falcone, his wife and fellow magistrate Francesca Morvillo, and three police escort officers, Vito Schifani, Rocco Dicillo, and Antonio Montinaro, on Highway A29 near the town of Capaci, Sicily. Four additional escort agents, Paolo Capuzza, Angelo Corbo, Gaspare Bravo, and Giuseppe Costanza, survived the blast. The attack, which came to be known as the Capaci bombing (Strage di Capaci), used roughly 400 kilograms of explosives packed into 13 drums that had been hidden in a drainage tunnel beneath the highway. The first car in Falcone's convoy took the full force of the explosion and was thrown into a nearby olive orchard, instantly killing its three occupants; the second car, carrying Falcone and his wife, crashed into a concrete wall and debris, and the couple, who were not wearing seat belts, were fatally ejected through the windscreen.
According to later testimony from Mafia informants Salvatore Cancemi and Santino Di Matteo, Falcone's killing was decided at meetings of the Sicilian Mafia Commission between September and December 1991 and orchestrated by boss Salvatore Riina, after the Supreme Court of Cassation confirmed convictions from the Maxi Trial on 30 January 1992. Through April and May 1992, Mafia members surveyed Highway A29 for a suitable attack site, procured explosives, and tunneled beneath the roadway. On the evening of 8 May 1992, roughly 400 kilograms of explosives were loaded onto a skateboard and positioned in the tunnel. On 23 May, as Falcone's convoy approached, Giovanni Brusca detonated the bomb by remote control from the hills above Capaci.
The killings prompted a national day of mourning. Funerals were held at the Church of Saint Dominic and broadcast live on national television, and regular television programming was suspended.
Italy's Direzione Investigativa Antimafia intercepted several of the conspirators in 1993 through phone calls referencing the bombing. Antonino Gioè died by suicide in custody after his arrest, while Santino Di Matteo and Gioacchino La Barbera began cooperating with investigators, naming other participants. In 1997, the Corte d'Assise of Caltanissetta convicted numerous defendants at first instance, sentencing Salvatore Riina, Leoluca Bagarella, and others to life imprisonment, and Giovanni Brusca, Salvatore Cancemi, and Santino Di Matteo to fixed terms of 26, 21, and 15 years, respectively; several other defendants were acquitted. On appeal in April 2000, the Court of Appeal of Caltanissetta upheld the 1997 convictions and acquittals but also sentenced several previously acquitted defendants to life imprisonment. The Court of Cassation annulled some of those convictions in May 2002. In 2003, part of the Capaci bombing proceedings was merged with the trial for the Via D'Amelio bombing, which killed Falcone's colleague Paolo Borsellino 57 days after Capaci; the Court of Appeal of Catania convicted twelve defendants in that combined trial in April 2006. Mafia boss Matteo Messina Denaro was sentenced in absentia to life imprisonment on 20 October 2020 as one of the bombing's instigators; after his capture in January 2023, the sentence was confirmed on appeal on 18 July 2023.
