The final season one episode featured Jarecki confronting Durst with a smoking gun, when Durst could not distinguish between his own handwritten letter and the infamous cadaver note that was believed to have been sent by Berman’s murderer. Durst, who was still mic’d, excused himself to the bathroom, which is where he would go on to say, “There it is, you’re caught. … Killed them all, of course.”

That piece of handwriting evidence was first introduced to the audience in the fifth episode of season one and, as The Jinx — Part Two‘s first episode explains, Durst went on the run after he watched that episode air one week prior to the finale. He was ultimately apprehended in New Orleans and was arrested the day before his bathroom confession was made public. The Jinx became an instant true-crime unicorn: an HBO docuseries just led to an arrest in a cold case — how did that happen?
