Durst, however, admitted using a paring knife, two saws and an ax to dismember the body, and that may result in a delay of his transfer to Los Angeles, because he was arrested with a revolver on Saturday. That's illegal for felons, and Durst did prison time after pleading guilty to evidence tampering and jumping bail. Louisiana authorities were considering Monday whether to press firearms charges.

Attorney Dick DeGuerin said outside court Monday that Durst didn't kill Berman, and is "ready to end all the rumor and speculation and have a trial."

When Durst approached the filmmakers and agreed to go on camera, he was still suspected in the killing of Berman, whose father was a Las Vegas mobster associated with Bugsy Siegel and Meyer Lansky, and the disappearance of his wife, who was declared dead long after she vanished in New York in 1982.

Los Angeles Deputy Police Chief Kirk Albanese said authorities arrested Durst on Saturday out of concern that he would flee the country.
