Mafia boss known as 'the Beast' who was behind 150 murders and ordered an informant's 13-year-old son be dissolved in acid dies of cancer aged 87 in prison hospital
Sicilian Mafia boss Salvatore 'Toto' Riina succumbed to his battle with cancer
Riina was serving 26 life sentences and is believed to have ordered the killing of more that 150 men
Riina once ordered the death of an informant's 13-year-old son, who was strangled and dissolved in acid
Italy's high court caused outrage earlier this year when it ruled that Riina 'deserved to die with dignity' in his own home as he fought terminal cancer
However the decision was left with a parole board which had not made a decision to free him and he died in prison hospital
