One of the cases at the center of HBO's The Jinx: The Life and Deaths of Robert Durst may have been reexamined in the past couple days after new evidence has been presented.

Robert Durst, who has been connected in the disappearances and deaths of three different people in the past 33 years, may be on trial again soon. The wealthy heir is the subject of The Jinx and it was suggested in Sunday night's episode that he knew where friend Susan Berman's body was on the day she was assumed to have died.

The investigation has apparently reopened over the past few weeks with Los Angeles investigators, a New York State Police investigator and the FBI all interviewing witnesses who have talked to authorities about the case.

"The New York State Police and the Westchester district attorney's office are still looking into Kathleen's disappearance," said Joseph C. Becerra, the NY State Police investigator, according to The New York Times. "It's always been an ongoing case, until there's a resolution one way or the other."

Berman's stepson Sareb Kaufman had called The Jinx producer Marc Smerling in Sunday night's episode with a letter sent from Durst to Berman back in 1999. Durst's handwriting was apparently a very close match to an anonymous note sent to the Beverly Hills PD about a "cadaver" present in Berman's house on the day of the alleged murder.

Durst was asked about the anonymous note and the suggestion that someone close to Berman had killed her.

"If somebody liked her, why kill her?" Durst responded. "And now you've taken this big risk. You're writing a note to the police that only the killer could have written."

It remains to be seen what will become of Durst and his various cases, though the families of the three victims may have some new hope in the weeks to come.

The Jinx: The Life and Deaths of Robert Durst is slated to conclude on Sunday, March 15 at 8 p.m. ET/PT on HBO.
