The “blond sheep” of the Bonanno family – a gangster with the unlikely name Duane “Goldie” Leisenheimer – took his place in mob history yesterday as the eighth turncoat to finger from the witness stand reputed godfather Joseph Massino for a slew of mob hits.

While Leisenheimer could never be a real wiseguy – his father is not Italian – it was the golden-locked Bonanno associate whom Massino turned to when he needed to go on the lam in 1982.

“Listen, I need a place to go for about 30 days. What about your parents’ house?” Leisenheimer recalled the former friend whom he calls “Joey” asking.

The crime family had recently been suckered by an undercover FBI agent using the mob moniker Donnie Brasco, and indictments were imminent.

Leisenheimer, who often acted as Massino’s driver, agreed to stay with his pal at his parents’ vacation place in Milford, Pa.

He never complained when the month-long getaway grew to nearly 2 ½ years.

“Over the years we had different houses. There was a hotel, and he used to go up to . . . Brooklyn,” Leisenheimer told Assistant U.S. Attorney Robert Henoch at Massino’s mob murder trial in Brooklyn federal court.

There were also many visitors – relatives and wiseguys – who would drive down to Pennsylvania.

Among the reputed mob boss’ more interesting guests from New York was his notorious pal John Gotti – and a woman named Linda whose husband was serving a prison sentence, Leisenheimer said.

Although the testimony about Linda left much to the imagination, sources close to the case said she was the married Massino’s girlfriend and traveled to Pennsylvania for romantic trysts.

Leisenheimer also remembered when love wasn’t in the air.

He testified that Massino gave the order to whack capo Cesare Bonventre when his underboss and brother-in-law Salvatore “Good Lookin’ Sal” Vitale came down to a house in Hemlock Farms, Pa.

“Joe said, ‘Cesare’s got to go’ . . . We sat down at the dining-room table and started figuring out how Cesare was going to go,” Leisenheimer testified, adding they settled on staging the hit in his Queens chop shop.

The precocious criminal started his career by stealing cars – which were a main hobby – and peppered his testimony with descriptions of gangsters’ vehicles.

Leisenheimer, 47, testified that he was just 12 when he got to know Massino, who was then driving a sky blue 1970s-era Oldsmobile with broken windows.

While some mobsters are expert at body disposal, Massino would often call on his friend’s automotive expertise in carrying out mob hits.

When Dominick “Sonny Black” Napolitano was killed in August 1981 in retaliation for bringing Donnie Brasco into his crew, it was Leisenheimer’s job to retrieve the murdered capo’s Coupe de Ville from under the Verrazano-Narrows Bridge.

Earlier, in the murder of three rival capos on May 5, 1981, Massino had borrowed Leisenheimer’s red van for hauling the bodies because he did not want to risk using a stolen car.

Leisenheimer also chauffeured Vitale that night, and put Massino and three gangsters involved in the slaying up in his apartment.

During the murder of Bonventre in April 1984, Leisenheimer waited with a radio near his chop shop on 58th Street in Maspeth. His job was to order the garage door to be opened as Vitale and the doomed capo rounded the bend in a car.

He also got rid of the victim’s brown Cadillac.

Massino looked glum yesterday as he listened to Leisenheimer describe how the pair ended their time on the lam in 1984.

Massino turned himself in, and Leisenheimer was immediately subpoenaed to testify against his pal.

Leisenheimer said he chose 1 ½ years in prison over an offer of immunity in exchange for his cooperation.

“I was a stand-up guy back then,” Leisenheimer testified.

But two decades later, Leisenheimer made a different choice.

He described how two FBI agents paid a visit to his house in June 2003.

“They said to me, ‘You know, you went to jail once for this guy. You don’t need to go to jail again,’ ” said Leisenheimer, who has married since his years on the lam, and held delivery jobs at both The Post and The New York Times.
