Westchester District Attorney Mimi Rocah said investigator slet themselves be “guided by Durst’s version of events” despite inconsistencies.
Durst was recently sentenced to life for a 2000 murder.
The real estate scion was recently sentenced to life in prison in California for killing a confidante who helped him cover up the slaying.
The wealthy real estate heir was charged in Westchester, New York, with second-degree murder in the decades-old disappearance.
Attorney Dick DeGuerin said he is very concerned for the real estate heir.
The former real estate scion is also facing potential charges related to the disappearance of his first wife in the 1980s.
Westchester District Attorney Mimi Rocah decided in recent days to take the case to a grand jury.
Jurors deliberated about 7 hours over three days before announcing they had reached a decision in the slaying of Susan Berman.
The accused murderer told the court that he was "mostly" telling the truth, but admitted, "there are certain things I would lie about, certain very important things.”
The real estate heir said he lied for years about sending police a note directing them to Susan Berman's body because he feared it implicated him in the killing.
