Giuseppe Greco Sicillian Mafia Member Life Story

According to Wikipedia and other online media sources I found some information on Giuseppe Greco. He was one of the most feared members of the Italian mafia and he was feared globally. Greco was a feared hit man and responsible for up to 50 murders during the 1980 mafia wars in Italy. Obviously it's hard to validate the information however several online media sources are reporting this. Giuseppe Greco documentaries can't be found online or on youtube however it's possible to find extra information about him due to various studies which are accessible online.
