"Once we get our case resolved in New Orleans, then we will work on getting him, Bob, to California where he can be brought to trial," Durst's attorney, Dick DeGuerin, told the Los Angeles Times.
"Bob Durst didn't kill Susan Berman and doesn't know who did. He's ready to get to California and prove his innocence," DeGuerin said.
The weapons charge stems from a gun that was found when Durst was detained at a hotel room in March on the eve of a six-part HBO documentary about him, the disappearance of his first wife in 1982, Berman's death, and the death and dismemberment of a neighbor in Galveston, Texas, in 2001. In that case, Durst admitted to chopping up the remains of 71-year-old Morris Black. Durst claimed Black was accidentally shot in a struggle after Black had threatened him with the gun. A jury found Durst not guilty of murder.
In the HBO documentary's final segment, Durst was recorded muttering to himself while using the bathroom. After an interview, he had failed to remove his microphone, which recorded him saying, "There it is, you're caught." Later, he said, "What the hell did I do?" Several seconds later, he continued: "Killed them all, of course."
Those comments followed a scene in which Durst was confronted with the similarity in handwriting in a letter he had sent to Berman and an anonymous note sent to Beverly Hills police directing them to the location of Berman's dead body. In addition, both Durst's letter and the note use the misspelling "Beverley Hills."
U.S. District Judge Helen Berrigan in Louisiana postponed Durst's trial on the weapons charge earlier this month to give attorneys time to work out a date to sign a plea agreement. On Thursday, she scheduled a change of plea hearing for Feb. 3.
