DEDHAM, Mass. (AP) – A state prosecutor has been fired for sharing audio tapes and other evidence in a murder case with the CBS news show “48 Hours Mystery,” according to a published report.

Susan Corcoran, who successfully prosecuted three men for the killing of 84-year-old Marina Calabro, was dismissed for giving the show tapes and other materials, The Patriot Ledger of Quincy reported Monday, citing law enforcement sources who asked not to be named.

Corcoran declined to comment on her dismissal. David Traub, a spokesman for Norfolk District Attorney William Keating, did not return two calls seeking comment.

“We did nothing wrong,” Al Briganti, the show’s executive editor, told the newspaper. “We acted with the permission of the trial judge. Whether it led to (Corcoran’s) dismissal, I can’t comment.”

CBS News issued a statement Tuesday saying 48 Hours had, with permission of trial judge Charles Grabau, recorded audiotapes that were introduced as evidence in the case as they were played in open court.

“To secure higher quality audiotapes of that same material, a routine procedure for broadcast news organizations, 48 HOURS asked permission to make an audio copy of the trial prosecutors tapes,” the statement said. “After making that copy, 48 HOURS returned the tapes to the trial prosecutor.”

Thomas Lally, 24, of Norton, was sentenced to life in prison in March after a jury convicted him of first-degree murder for Calabro’s death on Dec. 16, 2001.

In June, Marina’s grandnephew, Anthony Calabro, 23, pleaded guilty to second-degree murder for serving as the lookout. Witnesses testified at Lally’s trial that Anthony Calabro wanted his great-aunt killed so he could collect a $200,000 inheritance.

A third man, Jason Weir, 21, of Norton, reached a plea deal with prosecutors for a reduced charge of manslaughter.

Weir’s lawyer, Edward J. McCormick III, said he learned earlier this month from the district attorney’s office that Corcoran had left and that another prosecutor was now handling the case.

Corcoran, who was admitted to the Massachusetts bar in 1986, has handled murder and other major cases in Norfolk County for several years.
