Fredo Volpe is a capo in the Messina Family who has been a police informant since 1998. His LCPD profile states that he has collected thousands of hours of wire tap evidence. He is the brother of fellow capo Mark Volpe, who was believed to have sliced the tongue from a Messina member for hinting that Fredo was a possible informant.
Agreed to become an informant when evidence of plot by senior family members to castrate him was revealed.
The name "Volpe" means "fox" in Italian, which is quite ironic due his sneaky actions (informing the police).
His first name is likely ispired by the character Fredo Corleone played by John Cazale in The Godfather series of films. His surname may have been inspired by Albert Volpe a crime boss played by Carmine Caridi in The Godfather Part III.
