François Marcantoni (28 May 1920 – 17 August 2010) was a Corsican gangster and member of French Resistance.
[1] In 1942, during World War II, Marcantoni participated in a sabotage operation in Toulon.
[2] Marcantoni was under investigation in 1968 for the killing of Stevan Marković, a bodyguard for the film star Alain Delon.
One of the factors pointing in his direction was a letter Markovic sent to his brother Aleksandar wherein he wrote: "If I get killed, it's 100% the fault of Alain Delon and his godfather François Marcantoni".
Marcantoni spent 11 months in custody but was released in December 1969 because the prosecutor could not prove his guilt.
