7 thrilling serial killer documentaries to watch on Netflix
1) Conversations with a Killer: The Ted Bundy Tapes

This haunting documentary series stands out among various serial killer documentaries for its extraordinary storytelling approach.
The four-part series features old archival footage of Ted Bundy and includes several interviews with interrogators who worked closely on the case. What makes this one of the most disturbing serial killer documentaries is hearing Bundy’s actual voice as he confesses his crimes.
The killer went on to abduct, r*pe, and murder his victims, resulting in more than 30 girls in only a few years. The documentary reveals how Bundy used his charisma and intellect to attract the victims. The audience witnesses his manipulation techniques and his strange behaviour during his trial. His good looks and articulate speech fooled many people into believing he was a decent and innocent man.
2) Conversations with a Killer: The Jeffrey Dahmer Tapes

Jeffrey Dahmer is yet another notorious case featured in serial killer documentaries. The Netflix series follows the same theory as the Ted Bundy documentary, but emphasizes the Milwaukee Cannibal.
The documentary uses courtroom footage and investigative materials from Dahmer’s trial. He went on to kill and dismember 17 men between 1978 and 1991. His crimes involved cannibalism and necrophilia, which made his case one of the most disturbing in the history of crime.
The documentary explores how Dahmer evaded capture for a long time, regardless of multiple close calls with police. The show humanizes victims while examining systemic failures that further pushed Dahmer to continue his killings.
3) Night Stalker: The Hunt for a Serial Killer

Night Stalker narrates the real story of how Richard Ramirez was apprehended for his wrongdoings. The limited series focuses on the detective unit that tracked the Night Stalker during his reign of fear.
The documentary follows detectives Gil Carrillo and Frank Salerno collaborating to get hold of this unpredictable killer. Unlike many serial killer documentaries, this one emphasizes the investigative mission rather than glorifying the killer. Ramirez even breaks into houses at night, assaulting and killing victims out of the blue. His unhinged and unpredictable nature made him even scarier.
The documentary displays how fear gripped Los Angeles during the killing spree and shows the impact serial killers have on entire communities.
4) Conversations with a Killer: The John Wayne Gacy Tapes

John Wayne Gacy earned the infamous name Killer Clown for his alter ego as Pogo the Clown at children’s parties. This documentary continues Netflix’s popular series format. Gacy murdered more than 30 young boys and men, followed by burying most of the bodies under his house in Chicago.
This entry in the serial killer documentaries genre displays Gacy’s dual life. By day, he was a respected community member and successful businessman. And by night, he was a predator who invited victims to his house. The police unit discovered 26 bodies buried in Gacy’s crawl space in 1978. Among serial killer documentaries, this one stands out for displaying how killers can easily hide in plain sight.
5) This Is the Zodiac Speaking

This documentary explores the Zodiac killer case through various interviews with the Seawater family, who think their teacher, Arthur Leigh Allen, was a serial killer. The Zodiac spread terror around Northern California in the late 1960s and the early 1970s, taunting police with codes and letters.
What makes this unique among serial killer documentaries is its perspective. The Seawater children lived with a man they learn to believe was supposedly an infamous killer. The series features fresh evidence that provides new answers in these still-unresolved cases. The Zodiac cases remain open because the killer was not caught or identified.
6) I Am A Killer

This documentary series features death row inmates who are convicted of capital murder, detailing their crimes. What separates this from other serial killer documentaries is that it hears directly from the killers themselves.
Every episode focuses on a unique case, providing multiple perspectives on each crime. The series spans five seasons and covers different types of murderers. Some of the episodes also feature single murderers or serial killers.
The documentary includes interviews with victims’ families, prosecutors, and defense attorneys. These first-person accounts offer tragic insights into criminal psychology. The killers confess their motivations and describe their crimes in chilling detail.
7) Crime Scene: The Vanishing at the Cecil Hotel

The infamous Cecil Hotel comes into light when a guest, Elisa Lam, vanishes out of nowhere. While this documentary is not exclusively about serial killers, it explores the dark history of murders and mysterious deaths in the hotel.
The Cecil Hotel has housed various serial killers throughout history, including Richard Ramirez. And this documentary connects these cases while investigating Elisa Lam’s disappearance overnight. Later, an investigation revealed that her body was found in the water tank of the hotel under mysterious circumstances.
This documentary displays how locations can become associated with evil. Among serial killer documentaries, this one explores how crimes affect the places where they occur and examines broader themes of urban decay.
Serial killer documentaries on Netflix offer fans a shocking glimpse into the psychology of criminals, and these seven documentaries display the best of the genre, combining compelling storytelling and research.
