Accused Boston mobster James “Whitey” Bulger and one of his associates shot dead a bar owner in a phone booth for bragging about helping the “Winter Hill Gang” with another killing, an ex-convict and confessed murderer has testified.

A former criminal associate of James “Whitey” Bulger told jurors at the accused mob boss’s trial that he agreed to testify against his old friend after learning that his former gang pals had begun co-operating with law enforcement.

Former FBI agent John Connolly was sentenced yesterday to 40 years in prison for the 1982 mob-related killing of a Miami gambling executive.

A Mafia hitman who confessed to killing 20 people in the United States and who helped convict a rogue FBI agent of protecting gangsters could be released from prison next year under a plea deal backed by prosecutors.
