Court filings have shown that Durst has struck a plea deal with federal prosecutors on a weapons charge in New Orleans. 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.
