HBO Max / ID, 2023 — Oregon's Highway 20 serial crimes and John Arthur Ackroyd
Quick facts
What Is the Series About?
Lost Women of Highway 20 is a three-part true-crime docuseries that premiered on Investigation Discovery and Max (HBO Max) on November 5, 2023. The series examines a cluster of murders, disappearances, and sexual assaults that occurred along Oregon's U.S. Highway 20 — a rural corridor stretching from the Pacific Coast near Newport through the Cascade Range to Santiam Junction and beyond — from the late 1970s through the early 1990s. At the center of every episode is a single figure: John Arthur Ackroyd, a former Oregon Department of Transportation mechanic who investigators and journalists came to identify as a serial killer preying on women and girls traveling or living near the highway.
The series is directly rooted in Ghosts of Highway 20, a five-part investigative multimedia project published by The Oregonian/OregonLive that first named Ackroyd publicly as a suspected serial killer and connected several cold or unresolved cases to him. The documentary series expands that reporting into a visual narrative, weaving together survivor testimony, law enforcement interviews, and archival material.
The Case
The Highway 20 crimes span more than a decade and involve at least five named victims documented in the series.
Kaye Turner was murdered — with the killing eventually dated to 1978 — and her case became the legal cornerstone of the investigation. Ackroyd was charged with her aggravated murder and in 1992 received five life sentences in connection with her death, representing the most severe legal outcome of the entire investigation.
Rachanda Pickle, just 13 years old, disappeared in 1990. Her case is described by *People* magazine as central to the docuseries and to the broader pattern recognition that ultimately pointed toward a single offender. Ackroyd pleaded no contest in the Pickle case and was sentenced to an additional life term on December 6, 1993.
Marlene Gabrielsen survived. She was attacked and sexually assaulted by Ackroyd and is among the key witnesses whose account helped corroborate the pattern of predatory behavior along the highway. Her survival and testimony provide the series with a crucial first-person perspective that the other cases — defined by disappearance and death — cannot.
Melissa Sanders and Sheila Swanson also disappeared and are believed to have been killed in connection with the Highway 20 crimes. However, a critical legal distinction runs through the documentary: Ackroyd was never convicted in the cases of Sanders or Swanson. Despite being strongly implicated through journalism and investigative reporting, those cases remained legally unresolved at the time of his death in prison.
A pivotal moment in the investigative thread woven through the series is the discovery of a sealed court document by a local journalist — a find that helped tie the disparate missing-women cases along Highway 20 to a single suspect. This detail underscores how close the full pattern came to remaining permanently hidden, buried in court archives rather than exposed to public scrutiny.
Ackroyd's position as an Oregon Department of Transportation mechanic gave him routine, unremarkable access to the highway and its remote stretches — a professional cover that may have helped him evade early suspicion. He ultimately died in prison before the full legal accounting of his crimes was ever completed.
Production
The series was produced in close connection with The Oregonian/OregonLive's Ghosts of Highway 20 investigation, which is available to stream on YouTube and is explicitly recommended by the newspaper as companion viewing for audiences drawn to the documentary. The original reporting project is described as a five-part multimedia production that identified Ackroyd as a serial killer and brought renewed scrutiny to the cold cases of the Highway 20 corridor.
Executive producer Octavia Spencer is attached to the series in a producing capacity, lending the project a high-profile creative advocate whose involvement helped bring the story to a major platform. The director of the series was not confirmed in available sources at time of publication.
The documentary airs on Investigation Discovery (ID) and streams on Max (HBO Max), placing it within the true-crime programming infrastructure that ID has built over two decades while giving it the broader streaming reach of the Max platform.
Reception
People called the series "gripping" in its preview coverage, emphasizing the disappearance of 13-year-old Rachanda Pickle as the emotional and narrative anchor of the three episodes. The Oregonian/OregonLive, whose journalism forms the backbone of the series, reported on its November 2023 premiere and directed readers to the original Ghosts of Highway 20 video series for deeper context.
Rotten Tomatoes lists the series and its individual episodes, though critic and audience score data were not available in confirmed sources at time of publication. The IMDb title ID for the series is tt27497479, and the confirmed U.S. release date is November 5, 2023.
Viewer discussion on Reddit reflects engagement with the Highway 20 geography — particularly the Santiam Pass corridor — and a strong interest in the connection between the docuseries and the original Oregonian investigative project. Much of the public conversation has centered on renewed attention to the victims rather than to Ackroyd himself, which aligns with the series' framing.
The most substantive controversy attached to the series concerns case attribution. Ackroyd died in prison convicted of some crimes but never legally accountable for others. The families of Melissa Sanders and Sheila Swanson have never received a formal conviction in the deaths of their loved ones. The documentary's treatment of Ackroyd as the presumed perpetrator in those cases — while editorially supported by the reporting — sits in tension with the legal record, and that tension is one the series does not fully resolve, because the courts never did either.
The Case Today
With John Arthur Ackroyd dead, the Highway 20 cases are effectively closed from a prosecutorial standpoint. No other suspect has been publicly named or charged in the killings of Melissa Sanders or Sheila Swanson. The convictions and plea in the Turner and Pickle cases stand as the only formal legal outcomes from more than a decade of crimes along one of Oregon's most isolated highway corridors.
The documentary's November 2023 premiere renewed public interest in the cases and in the original Oregonian reporting, which remains accessible online. For the families of the unresolved victims, the series represents a form of public recognition that the justice system was unable to fully deliver. Whether any investigative or legal follow-up emerges from the renewed attention remains to be seen.
