Real-estate scion Robert Durst has reignited the investigation of his wife’s 1982 disappearance by shooting his mouth off in an HBO documentary — and now investigators are watching every minute of the miniseries for evidence against him, officials told The Post on Tuesday.
“I am complicit in Kathie’s not being here,” the 71-year-old said in a stunning admission on Sunday’s second episode in the six-part “The Jinx: The Life and Deaths of Robert Durst.”
Joseph Becerra, the top state police investigator who reopened the homicide probe 15 years ago, said, “We are watching the show very carefully for any useful information that is said in that documentary.”
The Westchester County DA’s Office is also watching, said spokesman Lucian Chalfen.
Durst made the provocative statement while discussing what he would now say to Kathie’s mother, with whom he had a rocky relationship.
On Tuesday, Durst — who admitted killing and dismembering a neighbor in 2001 but was acquitted of murder — refused to answer questions about his on-air confession.
“I’m planning to give a couple of interviews after the sixth episode,” Durst said.
During Sunday’s episode, Durst also admitted that he twice lied to NYPD detectives after Kathie’s disappearance.
He falsely told police that after putting his wife on a train from Katonah to Manhattan he had a drink with a neighbor.
Kathie’s corpse has never been found.He then fibbed about calling Kathie from a pay phone after she supposedly arrived at their Upper West Side apartment.
Her friend Geraldine McInerney said in the documentary that she was the last person to report seeing Kathie alive in New York on the night she vanished, Jan. 31, 1982.
Kathie confided that she was scared of Robert and didn’t want to go home, McInerney said.
When McInerney said to stay, Kathie looked at her friend as if she had “sprouted horns” and shot back, “Are you kidding? He’d kill me.”
Kathie returned to the Westchester cottage, but she soon made a desperate phone call to a friend, Gilberte Najamy.
Najamy recalled on Sunday’s episode that Kathie had a feeling “something” was about to happen.
“She said to me, ‘Gilberte, promise me if something happens, you’ll check it out. I’m afraid of Bobby,’ ” Najamy said.
