Notorious Sicilian mafia boss Nitto Santapaola dies in prison at 87

Benedetto "Nitto" Santapaola, a notorious Sicilian mafia boss who has been in prison for more than three decades, has died at the age of 87, two sources close to the matter said on Monday.

Santapaola, who was arrested in 1993 and was serving multiple life sentences for murder and other crimes, died in a high-security jail in Milan, one of the two sources said.

Italy's justice ministry did not immediately respond to a request for comment.

Santapaola, known as "il cacciatore" (the hunter) or "il licantropo" (the werewolf), led the mafia in the eastern Sicilian city of Catania from the late 1970s to the early 1990s.

He was tried and convicted as one of the instigators of the 1992 murders of Giovanni Falcone and Paolo Borsellino, two of Italy's most famous anti-mafia prosecutors.
