The reputed consigliere of the Colombo crime family pleaded guilty Thursday to a scheme to shake down the rival Gambinos because he wanted them to pay the medical expenses of a mob stabbing victim. Richard Fusco, 75, met on Staten Island with his captains to discuss how to proceed after a thug affiliated with the Gambinos stabbed Colombo associate Walter Samperi in May 2010. The Colombos wanted $150,000 - $100,000 of which would come from the Gambinos' cut from the 18th Ave. feast in Bensonhurst, Brooklyn. Fusco admitted there was an "implied" threat of retaliation and "I did nothing to dispel it." The meeting was secretly taped by Colombo turncoat Paul Bevacqua, who was wearing a wire. Meanwhile, if Fusco is hoping to get time shaved off his projected sentence of 18 to 24 months, he better correct his courtroom behavior. A courtroom clerk admonished the geezer gangster for making a nasty remark about the prosecutor before Magistrate Judge Ramon Reyes took the bench. Fusco, who is hard-of-hearing, was angry because the prosecutor wouldn't consent to removing his electronic monitoring device. He wished the prosecutor ill health in a voice loud enough to be heard all over the courtroom. "Keep your negative comments to yourself!" the clerk scolded him.
