LOUIS VALLARIO Indicted 13 years later.

June 21, 2002 -- He was the man John Gotti wanted dead. Yesterday, 13 years after the gangland execution of Staten Island businessman Fred Weiss, the feds finally caught up with the Gambino gangsters who allegedly fired off the Dapper Don's bullets.

Although seven members of the DeCavalcante crime family have been convicted on charges relating to the 1989 murder, U.S. Attorney Jim Comey said the indictments of two Gambino capos and two soldiers were the first time members of Gotti's "family" had been fingered for Weiss' murder.

Capos Louis "Big Louie" Vallario, 60, and Michael "Mikey Scars" DiLeonardo, 47, were charged with murdering Weiss as a favor to Gotti, who believed he was cooperating with the feds.

Edward "Eddie the Chink" Garafola, 64, "Sammy Bull" Gravano's brother-in-law and a soldier, was also charged with the killing, along with another soldier, Frank "Frankie Fap" Fappiano.

All four face life in prison. Fappiano, 40, already serving 51 months on racketeering charges, was separately charged with ordering and directing associates of the Gambinos to assault union official Frank Parasole, who died in January 1997 after a vicious bashing.

Weiss, a developer, had been indicted with a Gambino member for illegally dumping medical waste only months before he was shot in the head as he climbed into his Jeep in Staten Island.

Just before his slaying, he reportedly told friends his indictment was "nothing to worry about" and he wouldn't go to jail, possibly giving Gotti the idea that he was snitching.

But Gotti appeared to have been mistaken, with Comey denying yesterday that Weiss, 49, had been cooperating. "Mikey Scars" DiLeonardo's arrest yesterday came less than a year after he sidestepped racketeering charges in the sensational Atlanta Gold Club trial.

In that case, DiLeonardo was accused of extorting $100,000 from one topless club and offering mob protection to the owner of the strip club.

"Big Lou" Vallario was given three years' probation in May after being implicated in a waterfront bust. Vallario and DiLeonardo were being held pending a bail hearing next Thursday in Manhattan federal court.
