The Mullen Gang was an Irish-American gang operating in Boston. Gang members Paulie McGonagle (died November 1974) was a Boston mobster and onetime leader of the Mullen Gang, a South Boston street gang involved in burglary, auto theft, and armed robbery. During the war against Donald Killeen and his brothers, McGonagle successfully led the Mullens in a string of shootings which finally ended with Killeen's murder in 1972. After a truce was arranged with Whitey Bulger and the remnants of the Killeen organization, McGonagle remained angry about Bulger's accidental murder of his fraternal twin brother, Donald McGonagle. It is believed that this was one of the reasons for his disappearance in November 1974. His body was later excavated from a shallow grave on Boston's Tenean Beach. Tommy King (died 1975) was a Boston mobster and member of the Mullens during their gang war against Donald Killeen and his lieutenants Billy O'Sullivan and James J. Bulger during the early 1970s. Following Killeen's murder in 1972, he became an associate of Bulger and the Winter Hill Gang after his alleged involvement in the death of Paul McGonagle. In 1975, he disappeared following an altercation with Bulger in a Southie watering hole. He was suspected of having been killed by hitman John Martorano. Patrick Nee was born to an Irish-speaking family in Rosmuc, Ireland in 1944. He was brought to the US by his parents in 1952 and became a member of the Mullen Gang at the age of 14. He fought in several turf battles before joining the US Marine Corps. He arrived in Vietnam in 1965 and saw combat at Phu Bai. After his return to South Boston in October 1966, he rejoined the Mullens and became one of their leaders in the war against the Killeen brothers. Nee arranged the truce that ended the war by arranging a sit-down in Boston's South End. After being supplanted by Bulger, he moved to Charlestown, Massachusetts and switched increasingly to smuggling arms to the Provisional IRA. He currently resides in South Boston and is the author of the memoir, A Criminal and an Irishman. Feud with the Killeen Gang The Killeen brothers - Donald, Kenneth, George and Edward - were an Irish-American crime family which ran the bookmaking and loansharking in South Boston, Massachusetts. They used muscle to make collections, and to make examples of those who didn’t pay in a timely fashion.
