Mobfather no help to whacked Postie - rat

The mob's main man at the New York Post was marked for murder - even though his father-in-law was a top gangster, a Mafia turncoat testified yesterday.

Former Bonanno underboss Salvatore Vitale said Post delivery foreman Robert Perrino was whacked to keep him from blabbing about the crime family's lucrative rackets at the tabloid.

Perrino was shot in 1992 shortly after gangsters learned that Manhattan District Attorney Robert Morgenthau had secretly planted a bug in his office at the newspaper's South St. plant.

Vitale said the Bonanno bosses feared Perrino was "weak and might spill the beans" about the crime family's corrupt activities at the Post.

"If Bobby got indicted, they might put pressure on him and ...Bobby would cooperate," Vitale said in Brooklyn Federal Court at the trial of reputed soldier Baldassare (Baldo) Amato, 54, and associate Anthony Basile, 36, who are charged with Perrino's murder.
