Johnny is a character in Mafia: The City of Lost Heaven.
History
He is Billy's friend who somehow lives though his ordeal with Tommy Angelo in Better Get Used to It and brings the City Councilor and all of the corrupt politicians down on Don Salieri. He is seen again after Tommy, through pure coincidence, stumbles into the church where Billy's funeral is being held. Though he vanished from the church after identifying Tommy, his death may have been insinuated in the gun fight that followed as he may have been represented by one of the generic gangsters that Tommy kills in the church. Later when Salieri tells Tommy that the City Councilor must be killed after "the boy". This may be reference to Salieri wanting Johnny killed.
