”Little Nicky” Scarfo - He never snitched, but he did flip on his friends

Nicodemo Domenico "Little Nicky" Scarfo Sr. (March 8, 1929 – January 13, 2017) was a member of the American Mafia who became the boss of the Philadelphia crime family after the deaths of Angelo Bruno and Phil Testa. During his criminal career, Scarfo had a murderous reputation, also engaging in organized crime activities such as drug trafficking and gambling. In 1988, he was convicted of multiple charges including conspiracy, racketeering and first degree murder. His trial was met with damaging testimonies of several informants, who had carried out his murders. Scarfo died in prison on January 13, 2017, while serving his 55-year sentence. He is also the father of Nicky Scarfo Jr., a Lucchese family soldier, who was sentenced in 2015, to 30 years in prison for security fraud, racketeering, and illegal gambling.
