For decades the FBI's Boston field office used reputed Patriarca capo Mark Rossetti as an informant, and in order to protect its asset Michael Romano alleges the feds framed him just as he was close to uncovering that the Frank Salemme crew to which Rossetti belonged was responsible for the 1994 murder of Romano's son Michael Jr. as reported by Kevin Cullen for The Boston Globe: "Romano says a key witness against him - now retired FBI agent Michael Buckley, who was Rossetti's handler - was acting to protect Rossetti, not the public interest, when the government accused Romano of offering $15,000 to anyone who took out Salemme."
Rossetti was charged in October 2010 by the Massachusetts Attorney General with running a 30-member crew involving drug trafficking, gambling and loansharking, and further is a suspect in six murders according to a law enforcement source.
A six-person team from the Department of Justice currently is investigating the FBI's Boston field office over its long-standing use of Rossetti as an informant as reported by Michele McPhee for WCVB. Last November state prosecutor Dean Mazzone "said that the FBI was not truthful with investigators about Rossetti's informant status when the 18-month sting began with wiretaps at the reputed Mafiosi's East Boston headquarters, The Bunker."
Meanwhile, Rep. Stephen Lynch of South Boston has "filed a bill to give Congress a more active role in setting informant policy" as reported by The Boston Globe: "the Justice Department seems unable to prevent FBI investigators from developing relationships with unsavory characters and then standing by while their informants commit serious crimes; in some cases, the informants turn out to be every bit as dangerous as the targets they're informing on."
