BENEDICT CANYONFormer prosecutor,  Jeanine Pirro, is publishing a book on her experience of going after Robert Durst after he allegedly murdered Benedict Canyon journalist Susan Berman. Gallery Books will release He Killed Them All: Robert Durst and My Quest for Justice on November 3.

“Her books will be the definitive insider’s account of the true crime story that has captivated the country,” Gallery publisher Jennifer Bergstrom said. The title comes from a statement that Durst whispered to himself in a bathroom, which was unknowingly recorded during the filming of the six part HBO documentary series that chronicled Durst’s case, “The Jinx.” “What did I do? Killed them all, of course,” he says in the final scene of the documentary, hence the title of Pirro’s book.

Pirro played a big role in the creation of the documentary, and with the book she says: “I am thrilled to finally tell the full story behind my mission: I want this man, who became my nemesis, tried and convicted for murder.” Gallery, a Simon & Schuster imprint, said her book will prove her case “beyond a shadow of a doubt.”

Robert Durst, a wealthy real estate heir, was arrested in New Orleans in March 2015, in connection with the 2000 shooting death of Susan Berman. He is being held without bail because authorities determined he was a flight risk.

Back in 2000, Pirro re-opened the investigation into the disappearance of Durst’s first wife, Kathleen, who went missing in 1982. Assuming Berman was the closest confidant to Kathleen at that time, Pirro had her investigators set up a meeting to speak with her in December 2000. By the time Pirro got to California, Berman had been shot in the head and killed in her own home. The police had gotten a note with no stamp and no address that simply said “To the Beverly Hills Police Department” on the envelope, and inside, a piece of paper with Berman’s address and the word “CADAVER.”

Although Durst said he couldn’t imagine who would write that note, Pirro was convinced that he had killed her. “He knew we were coming out there, and he had to shut her up,” she said in March in an interview with Bloomberg Politics.

Pirro’s book is not the only one related to this case. San Diego author, Cathy Scott, has published through Barricade Books, “Murder of a Mafia Daughter: The Life and Tragic Death of Susan Berman.”
