Attorneys defending New York real estate heir
Durst, 71, was arrested at a Canal Street hotel on March 14 in connection with the murder of Susan Berman, a Los Angeles author and Durst's friend, 15 years ago.
In his hotel room, investigators found a .38 revolver and marijuana; Durst was charged with possession of a firearm by a convicted felon and possession of a firearm with a controlled substance.
Durst waived extradition, but Orleans Parish prosecutors have pursued the state charges, which, if he is convicted as a first-time offender, carry maximum sentences of 10 and 20 years.
After Berman's execution-style shooting, it was reported that Pirro's office had been looking to question her about Durst's involvement in the 1982 disappearance of his wife. After Kathleen Durst vanished, Berman had served as a spokeswoman for Durst, who later admitted that he lied to authorities about his actions the night he claims his wife left their Westchester County home and boarded a train to New York City.
Now, according to Wednesday's filing, Durst's attorneys want Pirro to testify to "confirm that, as part of her investigation, Ms. Pirro never requested an interview or otherwise contacted Susan Berman prior to Susan Berman's death in December 2000."
Pirro had vowed to convict Durst of the killing when she reopened the case, but never managed to charge him.
When Durst was later charged with murdering a neighbor in Galveston, Texas, and stood trial in 2003, his defense attorneys -- including his current lead attorney, Dick DeGuerin -- persuaded a jury that Pirro had persecuted Durst, forcing him to hide out in the Gulf island community dressed as a woman using a fake name.
After killing his neighbor in self-defense, he dismembered and dumped the body in the bay because he feared he would be blamed by his nemesis and others, they argued.
When Pirro appeared at Durst's last hearing at Orleans Criminal District Court on March 20, DeGuerin initially persuaded Magistrate Judge Harry Cantrell Jr. to remove her from the court as a potential witness for the defense, arguing she couldn't be both a lawyer and a journalist.
Her attorney and Assistant Orleans Parish Dist. Atty. Christopher Bowman soon returned to protest that removing Pirro was a constitutional violation, among other things. The judge eventually relented and allowed Pirro to return to court, where she sat in the front row of the gallery, eying Durst and taking copious notes.
At Thursday's preliminary hearing, the judge is expected to address a motion by Durst's attorneys to throw out his arrest based on the timing of the issuance of the underlying search warrants and Louisiana state law, which they argue did not prohibit Durst from having a gun.
Now the judge will be asked to set a hearing, potentially ahead of the scheduled one, to decide whether Durst can call Pirro to testify about her investigation as Westchester district attorney into his wife's disappearance.
Reached late Wednesday, Bowman said his office does not comment on open cases. Fox News did not respond to requests for comment.
Galveston Det. Cody Cazalas has appeared on Pirro's show to discuss how he investigated Durst. He said Wednesday that he is hopeful Louisiana officials can make their case against the man worth an estimated $100 million.
"DeGuerin wants to get out of Louisiana because I think he already realizes it's a strong case," Cazalas told The Times. "I think the warrants are good. He can put a lot of smoke and mirrors up, but [Durst] is a convicted felon. "
Cazalas said DeGuerin is trotting out the same "poor Bob" defense he used in Galveston back in 2003, pitting a persecuted Durst against Pirro. But if Durst really feared for his safety in New Orleans, Cazalas said, why not hire bodyguards instead of buying guns?
"He can hire a whole army, as much money as that man's got," Cazalas said.
In Galveston, Cazalas said, Durst "bought his way out of justice" with a high-profile defense team. But in Louisiana, the investigator said, "He's got a tab to pay with justice."
