Salvatore "Totò" Riina (Italian pronunciation: [salva'to?re (to't? r)ri'i?na]; 16 November 1930 – 17 November 2017 ), called Totò 'u Curtu (Sicilian for "Totò the Short", Totò being the diminutive of Salvatore), was an Italian mobster and chief of the Sicilian Mafia, known for a ruthless murder campaign that reached a peak in the early 1990s with the assassinations of Antimafia Commission prosecutors Giovanni Falcone and Paolo Borsellino, resulting in widespread public outcry and a major crackdown by the authorities.
He was also known by the nicknames la belva ("the beast") and il capo dei capi (Sicilian: 'u capu di 'i capi, "the boss of bosses").
Riina succeeded Luciano Leggio as head of the Corleonesi criminal organisation in the mid 1970s and achieved dominance through a campaign of violence, which caused police to target his rivals.
As a fugitive, Riina was less vulnerable to law enforcement's reaction to his methods, as the policing removed many of the established chiefs who had traditionally sought influence through bribery.
In violation of established Mafia codes, Riina advocated the killing of women and children, and killed blameless members of the public solely to distract law enforcement agencies.
Assassin Giovanni Brusca estimated he murdered between 100 and 200 people on behalf of Riina.
Although this scorched-earth policy neutralized any internal threat to Riina's position, he increasingly showed a lack of his earlier guile by bringing his organisation into open confrontation with the state.
After 23 years living as a fugitive he was captured in 1993, provoking a series of indiscriminate bombings of art galleries and churches by his organisation.
His lack of repentance subjected him to the stringent Article 41-bis prison regime until his death.
