The address was 799 East Third Street, where Whitey Bulger set up a murder assembly line. It was the 1980’s and Bulger and his bloodthirsty crew were selling cocaine, running guns, extorting other gangsters and killing young women…and burying the bodies in the basement of a little house in South Boston.

The first of those victims was Arthur “Bucky” Barrett. His murder would go down as one of the gang’s most cruel and unnecessary killings. Even Stevie “the Rifleman” Flemmi later claimed he was shocked by Whitey’s brutality.

John “Zip” Connolly was perhaps the most corrupt special agent in the tawdry history of the Federal Bureau of Investigation.

A native of South Boston like the Bulger brothers, he handled their dirty work for a quarter century, becoming a multi-millionaire on a policeman’s salary. As a decorated G-man, he made training videos for the FBI academy, which you will hear, instructing young agents how to handle organized-crime informants. At the same time, though, he was tipping his underworld paymaster Whitey to informants so that they could be murdered.

“Never try to out-gangster a gangster,” Connolly said, but now he’s serving a life sentence in a Florida state prison for a gangland hit he orchestrated in Miami.
