Family of the ex-wife of troubled New York real estate heir Robert Durst have asked a judge to declare her legally dead 34 years after she was last seen.
In affidavits filed in Manhattan Surrogate's Court this week, Kathleen Durst's sisters and mother ask a judge to issue a death certificate.
They need a judge's declaration to pursue a wrongful death lawsuit against Robert Durst.
The family believes the 72-year-old millionaire killed Kathleen Durst in 1982. He hasn't been charged in connection with her disappearance.
Los Angeles prosecutors allege Durst killed a friend in 2000 to keep her from talking to authorities about Kathleen.
Attorney Richard DeGuerin says Durst is not responsible for the death or the disappearance.
He pleaded guilty last month to a weapons charge in Louisiana.
