The legal team of The Jinx subject Robert Durst have now acknowledged that he wrote the note that ultimately tipped off police regarding the location of the body of a friend he's been alleged to have killed.

"This does not change the facts that Bob Durst didn't kill Susan Berman and he doesn't know who did," lawyer Dick DeGuerin said in comments to the Associated Press. The concession was revealed via a court filing last week in Los Angeles Superior Court. The 76-year-old Durst has pleaded not guilty in Berman's murder, despite having previously shared his assessment on the popular Jinx docuseries that the letter in question could only be the work of the murderer. That latter was inside an envelope with a misspelled version of Beverly Hills ("Beverley Hills") and notably included the word "cadaver." 

Following a discussion about the letter, specifically its comparison to another bit of handwriting Durst had already admitted was his, the Jinx subject famously went to the restroom mid-interview and murmured to himself while unaware of a live mic. "What the hell did I do? Killed them all, of course," he said on the Jinx finale.

The killings of Berman and Durst's neighbor Morris Black, prosecutors argue, was part of a larger effort to suppress information connected with the prior killing of Kathleen McCormack. She went missing in 1982 and was declared dead years later. A body, however, was never found.

The Jinx ran on HBO in February and March of 2015, inspiring a multitude of mainstream news coverage and renewed questions centered on its subject's personal history.
