Sal was an associate of a mafia crime family, who Castle met while researching Derrick Storm in the early days of his writing career. When investigating the murder of Doctor Joshua Leeds for his role in a witness protection program, Castle decided to talk with Tenor, reasoning that the mob would already know who Leeds had performed plastic surgery on, and the search could provide them with vital information."@en . .

"Sal Tenor is a character portrayed by Robert Costanzo in the ABC crime series Castle. Sal was an associate of a mafia crime family, who Castle met while researching Derrick Storm in the early days of his writing career. When investigating the murder of Doctor Joshua Leeds for his role in a witness protection program, Castle decided to talk with Tenor, reasoning that the mob would already know who Leeds had performed plastic surgery on, and the search could provide them with vital information. Although Tenor initially ordered Castle taken out back, he laughed it off with reassurances that he was just kidding. Talking with Castle, Tenor revealed that Leeds had been murdered to find information on the location of Jimmy 'The Rat' Moran, a former hitman for the Spolano crime family who was forced out of the family when the previous head died and his son took over, Moran turning State's Evidence to avenge himself on the family. When the Spolanos discovered Moran's location because he was brought out of hiding to talk with Castle and Beckett, Castle briefly wondered if Tenor had tipped them off, but Beckett rejected that possibility as Tenor's associates in a rival family would benefit from the Spolanos being taken out of the picture. He is mentioned in Season 5 episode Murder, He Wrote, where Castle reveals he is friends with mob boss Vincent \u201Cthe Scar\u201D Cardano, saying he tried to make Castle and Beckett form a relationship together."@en .
