On the eve of Robert Durst's trial resumption, he is facing new allegations that his brother and father helped cover up the murder of Kathie Durst, who disappeared in 1982.
The explosive claim was made by lawyers representing the family of Kathie Durst, saying that brother Douglas and father Seymour were involved in the cover-ups.
Robert allegedly killed Susan Berman in 2000 by shooting in her the back of the head, with prosecutors believing she had information on Kathie's disappearance, which may have motivated Robert to allegedly kill her.
Robert Durst, 78, has been in jail since 2015 on charges related to Berman's death, with his trial in her murder set to resume this week.
Cathy Russon of Law & Crime Network tweeted about the new allegation on Monday while Robert Durst was in the courtroom.
Kathie Durst, the wife of Robert, has been missing for almost 30 years after disappearing from the couple's South Salem, New York home on January 31, 1982.
Her body has never been found and Robert has not been charged with her death, though authorities believe he is likely responsible, according to the New York Post.

The Westchester District Attorney's office recently relaunched an investigation into Kathie's disappearance.
'The Westchester DA’s Office Cold Case Unit was established to review and reinvestigate unsolved homicides. It is reviewing a number of cases, including the murder of Kathie Durst,' said Westchester County District Attorney Mimi Rocah.
News 12 reports DA's office has been conducting interviews for several weeks.
Her family met with investigators last month, with three of her four siblings present for that meeting.

After opening arguments and a couple of days of testimony last year, Robert's trial in the death of Berman was delayed for 14 months due to COVID-19.
Judge Mark Windham is set to question the 23 jurors about the case on Monday before the trial resumes on Tuesday.
Durst's lawyers claim the jury can no longer be impartial due to the long layoff and high-profile nature of the case.
The real estate heir was the subject of The Jinx, an HBO documentary that ends with Durst seemingly confessing to murder.
The defense also wants to postpone the trial because Durst is suffering from health issues, including bladder cancer.

Lawyers filed an emergency motion asking for his trial to be delayed indefinitely due to a 'myriad of life-threatening issues.'
'We are very concerned about his health,' Durst’s lawyer Dick DeGuerin told CNN.
'He's really gone down in the last year. He's been in and out of clinics and hospitals frequently.'
Lawyer Dick DeGuerin told DailyMail.com: 'His health has deteriorated alarmingly over the past fourteen months since the trial was shut down at the beginning of the Covid pandemic.
'I'm concerned about whether he can withstand the rigors of trial.

'We are continuing our request for mistrial through a Writ to the appellate courts, which means we have appealed the trial court's denial of our latest motion for mistrial.'
Durst was present at his most recent court hearing on March 17 but looked frail and sounded weak.
He is being held in the Twin Towers correctional facility in Los Angeles.
His legal team said they are willing for him to pay for his own security, be subjected to GPS monitoring, and have a high bail amount if he is released to a medical facility.
In July, a judge denied a request for a mistrial after a delay from the coronavirus outbreak.
In 2003, Durst was acquitted in Texas of murdering neighbor Morris Black, whom he admitted to dismembering after shooting him in self-defense during a struggle inside the Galveston apartment they shared.
