The documentary directly led to his arrest. The new evidence (the "cadaver" letter) and the bathroom confession were used to re-charge him with the first-degree murder of Susan Berman.
Durst’s legal team tried everything—including arguing that the HBO microphone recording was illegal under wiretapping laws. The judge disagreed. The Jinx- The Life and Deaths of Robert Durst -...
The producers, listening in the control room, sit in stunned silence. They know they have just recorded a confession that will send him to prison. They call the FBI. The Jinx aired its finale on March 15, 2015. That very morning, Robert Durst was arrested at a New Orleans Marriott hotel, a .38 revolver and a mask in his room. The FBI had been waiting.

Years later, Jarecki’s team unearths a letter Durst wrote to Berman years before her death. The handwriting—specifically the spelling of "Beverley" (with an extra 'e') and the blocky, tilted 'd'—is an identical match. The judge disagreed
In the pantheon of true crime documentaries, few have achieved the cultural impact, narrative tension, or real-world legal consequence of Andrew Jarecki’s 2015 HBO series, The Jinx: The Life and Deaths of Robert Durst . It sits alongside Making a Murderer and The Staircase as a landmark of the genre, but with one crucial distinction: unlike those series, The Jinx captured its subject—billionaire real estate heir Robert Durst— confessing to murder on a live microphone during the final interview.
When confronted with this, Durst doesn't confess. He confirms it. He says, "I can’t say it’s not my handwriting." He then proceeds to claim that only the killer could have written the letter—meaning, by his own logic, he is the killer. It’s a breathtaking moment of psychological slippage. The finale, What the Hell Did I Do? , is a masterpiece of tension. After the handwriting revelation, Durst is clearly agitated. He asks to use the bathroom before the final interview segment.
