The complaint was filed in Lewisboro Town Court in New York on October 19, district attorney spokeswoman Jess Vecchiarelli said.
Kathleen McCormack Durst was last seen in 1982 and declared legally dead in 2017. Her body has not been found.
Durst is battling Covid-19.
Durst has been charged with the first-degree murder of Berman in 2000 at her Beverly Hills home, hours before she was set to talk to investigators about the mysterious disappearance of Kathleen McCormack Durst.
Her family is “very happy” Durst has been charged, attorney Robert Abrams said.
The family will not have further comment until the case proceeds, he said in a statement.
Murder date ‘on or about’ January 31, 1982
Robert Durst has been charged with one count of murder in the second degree in the alleged killing of his former wife in Lewisboro, New York, “on or about” January 31 1982, court documents say.
