Two names still carry weight in the history of the American Mafia: Anthony “Gaspipe” Casso and Salvatore “Sammy the Bull” Gravano. Both were ruthless killers who rose to the rank of underboss in New York’s Five Families, but their legacies took very different paths—one defined by unchecked violence, the other by a historic betrayal that brought down the Gambino family. Anthony Casso, born in 1942 in Brooklyn, grew up surrounded by crime. His father, a dock worker with underworld connections, reportedly carried a lead pipe for protection—a detail that earned the younger Casso his nickname.
After dropping out of school at 16, Casso joined the South Brooklyn Boys gang and later became an associate of Christopher “Christy Tick” Ferrara, a prominent Lucchese family captain. Casso officially became a made man in the Lucchese family in 1974 and eventually rose to underboss alongside boss Vittorio “Vic” Amuso. Together, they turned the family into one of the most feared and profitable Mafia organizations in the country, with operations spanning drug trafficking, extortion, truck hijacking, and murder-for-hire schemes. What made Casso particularly dangerous was his ability to corrupt law enforcement.
He had two NYPD detectives, Louis Eppolito and Stephen Caracappa, on his payroll. Known as the “Mafia Cops,” they fed Casso information on rival mobsters and even participated in killings on his orders. The revelation of this infiltration became one of the most shocking police corruption scandals in U. S.
history. Casso’s reputation for violence was legendary. He reportedly ordered or participated in over 36 murders, including hits on informants, rivals, and even his own associates. His paranoia grew as he became convinced that betrayal lurked within his own organization, making him even more unpredictable and dangerous.
Salvatore Gravano took a different path to power. Born in Brooklyn on March 12, 1945, he started in local street gangs before joining the Colombo crime family. He later switched to the Gambino family, where his loyalty and efficiency in carrying out orders caught the attention of John Gotti. Gravano played a key role in the murder of Gambino boss Paul Castellano in 1985, a move that cleared the way for Gotti to take control of the family.
As Gotti’s underboss, Gravano admitted to involvement in 19 murders and became known as both a thinker and a fighter—someone who could command men as effectively as he could kill them. In 1991, Gravano made a decision that changed the Mafia forever. He became a government informant and testified against John Gotti, helping the FBI convict the so-called “Teflon Don” and dismantle much of the Gambino family’s power structure. His testimony marked one of the most significant betrayals in Mafia history and encouraged other mob members to cooperate with federal prosecutors.
Gravano entered the Witness Protection Program but later left it to live openly in Arizona. He started a construction business and attempted a quieter life, but in 2000 he was arrested for running an ecstasy trafficking ring. He served 17 years in prison and was released in 2017, remaining in the public eye with interviews and commentary on his life in organized crime. Casso, by contrast, never sought public recognition.
He remained a shadowy figure who ruled through secrecy and fear. His arrest exposed the Mafia Cops scandal, but his attempt to cooperate with the FBI backfired. Federal authorities considered him too unstable and pulled his plea deal, leaving him to die in prison in 2020. Comparing the two men, their impacts differ.
Gravano’s decision to flip ended Gotti’s reign and inspired a wave of defections that weakened the Mafia’s grip on New York. Casso’s legacy is tied to the corruption he seeded within the NYPD and the brutality he inflicted on those around him, including his own men. While Gravano enjoys a lasting public legacy as a celebrity mobster turned informant, Casso is remembered as a cautionary tale of paranoia, unchecked power, and betrayal.
Both men left deep marks on organized crime, but only one is still alive to tell his story.
