Filmmaker Andrew Jarecki's HBO miniseries The Jinx made a pretty solid case that extremely creepy real estate scion Robert Durst had a hand in multiple killings. And next summer, the 72-year-old will finally have to deal with a murder charge for a 15-year-old incident in California, according to the Los Angeles County District Attorney's Office.The New York Times reports that Durst will be extradited to Los Angeles by mid-August 2016 to stand trial for allegedly shooting his friend, writer Susan Berman, back in 2000. Durst has been jailed in Louisiana since March on a weapons charge, for which he apparently reached a plea deal.The Jinx hypothesized that Durst murdered Berman because she was considering speaking to cops about his alleged role in the disappearance of his wife in 1982. Berman was found dead in her home with no sign of forced entry.Durst's lawyers maintain that he's innocent, regardless of the whole hot-mic bathroom rant that closed out The Jinx."Bob Durst didn't kill Susan Berman and doesn't know who did," Durst's lawyer, Dick DeGuerin, said in a statement Tuesday. "He is eager to go to trial and prove his innocence."
