You’ve heard the chilling tapes from Ted Bundy and John Wayne Gacy. Now, Conversations with a Killer: The Jeffrey Dahmer Tapes dives into the case of one of America’s most notorious serial killers. 

When Milwaukee police entered the apartment of 31-year-old Jeffrey Dahmer in 1991, they weren’t prepared for what they’d find. From a freezer full of human heads to decomposing body parts, the discovery amounted to the grisly personal museum of a sadistic killer. Dahmer quickly confessed to sixteen murders in Wisconsin over the span of four years, plus another murder in Ohio — but the most shocking revelation involved acts of necrophilia and cannibalism.

Back for a third iteration, Conversations with a Killer uses never-before-heard audio interviews between Dahmer and his defense team to answer the big question: Why was Dahmer, who had been convicted of sexual assault of a minor in 1988, able to avoid suspicion and detection from police as he stalked Milwaukee’s gay scene for victims, many of whom were people of color? The three-part docuseries not only delves into the killer’s warped psyche but also examines police accountability through a modern-day lens. As seen in the trailer above, the upcoming docuseries highlights interviews with those who worked closely with Dahmer, including his lawyer Wendy Patrickus, during his high-profile case. 

With Ryan Murphy’s scripted series Dahmer streaming soon, you can learn even more when Conversations with a Killer: The Jeffrey Dahmer Tapes premieres on Oct. 7.
