Former Prosecutor Jeanine Pirro Offers Insider’s Look Into Kathleen Durst's Disappearance

— -- UPDATE: An earlier version of this report stated that the staff of the apartment building that Kathleen and Robert Durst shared at the time of her disappearance were Durst employees. However, the Durst Organization says at no time has it owned the building or employed any of its workers. The report has been updated.

Robert Durst was the millionaire scion to a prominent New York real estate family, but some who got close to him had a curious way of disappearing or turning up dead.

His first wife, Kathleen Durst, vanished in 1982. His best friend, Susan Berman, was found shot dead in her Los Angeles home in 2000. And Durst admitted to killing and dismembering Morris Black, a neighbor he lived next to in Galveston, Texas, in 2001.

Kathleen Durst, married to Robert Durst, was a fourth-year medical student when she went missing. She was officially declared dead 19 years later in 2001, though her body has never been found.

But former prosecutor Jeanine Pirro, who is credited with re-opening her cold case, has harsh words for Robert Durst who she believes should be held responsible for her disappearance.

“He should be shot in the back of the head and his body should be dismembered, like he did to everyone else,” Pirro told ABC News' “Nightline.”

Kathleen’s case and the other cases were detailed most recently in the hit HBO documentary series, “The Jinx: The Life and Deaths of Robert Durst,” for which Durst sat down for an extensive interview with filmmaker Andrew Jarekci.

The documentary helped inspire Pirro to write her book, “He Killed Them All: Robert Durst and My Quest for Justice,” released this week. In the book, Pirro gives a detailed insider’s account of the Durst saga.

For more than 15 years, Pirro, a former Westchester County, New York, district attorney, has been obsessively trying to connect Durst to his wife’s disappearance, returning again and again to the Pine Barrens of southern New Jersey. It is where Pirro thinks Robert Durst buried Kathleen’s body.

“Every time I come out here, I think she’s here. Her spirit is here,” Pirro said. “There was a vibrant, beautiful woman who is about to go out in an area -- a field of medicine that ... she was so proud of. He took it from her. He just ripped it from her. She’s here and she’s waiting for someone to find her.”

In 2000, Pirro’s team searched the lake near Durst’s country home in Westchester, but found nothing. In “The Jinx,” Durst was asked about the search and said the divers were “obviously looking for body parts, looking for something that can be used as evidence.”

That statement, Pirro said, was a revelation.

“As opposed to saying ‘my wife, my wife’s body, Kathy’s body,’ he says ‘body parts,’” Pirro said. “I jumped up and said, ‘Oh my God, he chopped her up as well,’ because in his mind he knew whether it was in the lake or wherever that his wife’s body had been cut up at that point.”

Shortly after her disappearance, a list was found in Robert Durst’s trash with the words “town dump, bridge, boat, shovel.” Pirro claims that when analyzed it’s a virtual road map to the South Jersey Pine Barrens, which she said was an area popular with real estate developers at the time.

“He would have been familiar with this area as a dumping ground,” Pirro said. “The perfect hiding spot -- that he would have known about.”

“She is here, there is no doubt in my mind she’s here,” she continued. “And the family deserves to be able to bury her in a place of respect and dignity.”

Pirro says she has been coming to the Pine Barrens since Kathleen’s cold case landed on her desk in the Westchester D.A.’s Office. Reading Kathleen’s file, Pirro said she immediately suspected Durst, who has never been charged in his wife’s disappearance.
