Giuseppe Marchese (born c 1962) was a member of the Sicilian Mafia, who turned state witness (pentito). Giuseppe Pino Marchese was born in Palermo in a family with long-standing ties to the Mafia. His father Vincenzo and his uncle Filippo Marchese were both members of Cosa Nostra.
He learned the hard way what it meant to be born in a Mafia family. When he was 16 he wanted to marry a girl. However, her parents were separated, which, according to the rules of Cosa Nostra, was not allowed. Giuseppe’s brother made the suggestion that he "clean up the family mess" and marry an orphan instead of the daughter of separated parents. In other words, Giuseppe was supposed to kill his girlfriend’s father. If he would not do it, his brother would. Giuseppe broke off the relationship.
In 1980, just 17 years old, Giuseppe Marchese was initiated into the Mafia by Salvatore Riina and Leoluca Bagarella as ‘reserved’ man of honour affiliated with the Corleonesi. His membership of Cosa Nostra was to be kept confidential in order to work exclusively for Riina and his uncle. He became one of the many killers at the disposal of the Corleonesi in the Second Mafia War.
He was only 19 when he participated in the so-called "Christmas Massacre" when, on the afternoon of December 25, 1981, in Bagheria, three Mafiosi – including Giovanni Di Peri, the boss of Villabate – and an innocent bystander were murdered. Giuseppe Greco and Marchese's uncle Filippo Marchese also took part in the bloodshed.
Giuseppe Marchese was captured on January 15, 1982, and imprisoned for his role in the Christmas Massacre. His conviction was secured by the fact that his fingerprint was found on the steering wheel of one of the getaway-cars (the forensic scientist, Dr. Paolo Giaccone, who found and identified the fingerprint was subsequently shot to death by Rosario Rotolo, one of Filippo Marchese's killers; at the Maxi Trial, Rotolo was convicted of this murder.)
