New documentary reframes Ted Bundy case through detective’s interviews and investigative innovations
A new Hulu documentary, Ted Bundy: Dialogue with the Devil, revisits the Bundy case through the recorded prison interviews of Detective Bob Keppel, offering fresh perspective on both the killer and the investigators who pursued him. Keppel—who died in 2021 just short of his 77th birthday—features prominently in the film, along with previously unheard interviews from people close to the case, including Bundy’s half-brother, Keppel’s mentor, and Keppel’s son.
Keppel first encountered what became a serial murder investigation in the Pacific Northwest in 1974. After Brenda Ball disappeared in June, Keppel was reassigned to replace an ailing homicide detective. On July 1 he joined partner Roger Dunn; two weeks later Janice Ott and Denise Naslund vanished from Lake Sammamish State Park. In September human bones were discovered in a wooded area—later identified as the dumping ground for Ott, Naslund and another victim. Additional remains were found near Taylor Mountain, signaling to Keppel that a serial killer was operating in the region.
Recognizing patterns and managing information were central to Keppel’s approach. He stressed that “recognition is the single most important concept in a serial murder investigation,” warning that mismanagement of information dramatically reduces the chance of solving linked crimes. To narrow an initial pool of more than 3,000 potential suspects, Keppel fed lists into a mainframe computer, reducing the field to 25 names; Ted Bundy was among them, though he had left the state. When Utah authorities later arrested Bundy, Keppel and Dunn briefly confronted him in Seattle, securing a promise to talk—though Bundy returned to Utah and contact ceased.
Bundy’s escapes and the subsequent recapture in Florida (1978) unfolded while Keppel was completing doctoral studies at the University of Washington, where he deliberately pursued coursework and mentors that would equip him for complex homicide work. He studied with forensic psychiatrist John Liebert and memory researcher Elizabeth Loftus and took a role as chief investigator for the Washington State Attorney General’s Office.
In 1984, Bundy reached out to the Green River Task Force in a letter offering his insights into the Green River murders. Keppel, after consulting his mentors, traveled to Florida with Detective Dave Reichert to interview Bundy. Keppel described a deliberate interview strategy: match the interviewee’s language and sentence structure, avoid over- or underchallenging him, and use behavioral cues to detect evasions or admissions. One specific tactic was to pose an obviously false statement to see how Bundy defended it—his manner when lying provided clues to his comfort with deception. Keppel also observed that Bundy “would talk a lot about nothing when things approached the truth,” a sign the investigator used to inch toward admission without triggering a shutdown.
Although Bundy did not fully confess at that time, the dialogue laid groundwork for later revelations. Shortly before his execution in 1989, Bundy spoke with Keppel and admitted to the murders of Janice Ott and Denise Naslund, identified Georgeann Hawkins as another victim, confirmed eight names on Keppel’s list, and supplied mutilation details that corroborated investigative suspicions.
One of Keppel’s lasting impacts was his push to apply systematic data analysis to homicide investigations. He helped develop the Washington Attorney General’s Homicide Investigation Tracking System (HITS), software designed to collect, collate, and analyze characteristics of murders and predatory sexual offenses across the state to improve detection and apprehension of serial offenders.
The documentary highlights Keppel’s methodical, patient interviewing style and investigative innovations. While some viewers may miss Keppel’s narrational voice and find the film could be more tightly edited, the program brings valuable archival material and new interviews into public view, emphasizing how careful detective work and applied research can advance homicide investigations.

Logical explanation/commentary
– Keppel’s work illustrates how combining behavioral interviewing techniques with systematic data collection strengthens investigations into serial crimes. His strategy—matching language, observing micro-patterns in speech, and using computerized case management—demonstrates a blend of psychology and practical case work that can surface links missed by isolated inquiries.
– The documentary’s value lies less in uncovering new crimes and more in showcasing investigative craft: how persistence, methodical learning, and cross-disciplinary training (forensic psychiatry, memory research, data systems) can produce breakthroughs in difficult cases.
Summary
Hulu’s Ted Bundy: Dialogue with the Devil foregrounds Detective Bob Keppel’s recorded interviews and investigative methods, tracing his role from the 1974 Pacific Northwest serial killings through his later work developing HITS and interviewing Bundy in Florida. The film offers fresh archival material and interviews that highlight Keppel’s patient, research-driven strategies and their influence on modern homicide investigation.
Hopeful angle
While the Bundy case remains grim, the documentary underscores progress: investigators like Keppel pushed policing toward evidence-based, interdisciplinary methods that improve the chances of solving violent crimes and preventing future victims. Keppel’s legacy—teaching, developing tools like HITS, and refining interview techniques—reflects enduring improvements in how law enforcement approaches complex homicides.
