While among the Sicilian side there were Salvatore "Little Bird" Greco and his cousin Salvatore Greco, also known as "l'ingegnere" or "Totò il lungo", Giuseppe Genco Russo, Vincenzo Rimi and Filippo Rimi, Angelo La Barbera, Gaetano Badalamenti, Totò Minore, Rosario Mancino, Calcedonio Di Pisa, Cesare Manzella, Gioacchino Pennino and Tommaso Buscetta.
[3][5] There are no first-hand accounts of the meeting, except for the version of Mafia turncoat Tommaso Buscetta, who denied a summit ever took place at all.
According to Buscetta, Bonanno did stay at the Grand Hotel des Palmes and received many guests all the time, but there was no summit as such.
According to Buscetta a gathering took place in a private room at the Spanò seafood restaurant on the evening of October 12, 1957, where Bonanno was fêted as the guest of honour by his old friend Lucky Luciano.
They were charged with criminal conspiracy and narcotics and currency rackets and tobacco smuggling and had been present at the 1957 Palermo summit.
Among the indicted were Bonanno, Bonventre, Galante, Sorge, Magaddino, John Priziola, Raffaele Quasarano, Frank Coppola and Joe Adonis.
The trial began on 14 March 1968, after a five-year investigation that uncovered a transatlantic drug trafficking network operating since 1957.
Judge Vigneri had travelled to the U.S. to interrogate Joe Valachi, the first member of the Italian-American Mafia to testify against the organisation.
