Matthew Joseph "Matty the Horse" Ianniello (June 18, 1920 – August 15, 2012) was an American mobster with the Genovese crime family of New York City, of which he was once the acting boss.

[1] The Nevada Daily Mail reported Matthew was at the cash register that night but "the proprietor dove into the kitchen and lay on the tile floor with his hands over his eyes as soon as Sonny Pinto (Carmine Dibiasi) and two out-of-town torpedoes known only as Cisco and Benny came in the side door blasting.

The next thing he knew, Pete "The Greek" Diopoulis, a Gallo bodyguard, was pushing a gun in his face and pulling the trigger but only clicks came out because it had been emptied trying to save Joey.

"[10] In 1985, along with Vincent Asaro, he was alleged to have demanded up to $1 million when seedy properties owned by gangster Michael Zaffarano were sold to legitimate real estate developers.

[11] On February 28, 1985, Ianniello was indicted in federal court in New York on charges of racketeering involving the operation of several restaurants, bars and carting companies.
