John Arthur Ackroyd: Oregon Highway Serial Killer and Suspected Murderer
Overview
John Arthur Ackroyd (March 7, 1949 – June 30, 2016) was an American serial killer and convicted rapist who worked for the Oregon Department of Transportation as a highway mechanic. For decades, Ackroyd was suspected of being responsible for a series of murders, disappearances, kidnappings, and sexual assaults that occurred along highways and remote forested areas in Oregon during the 1970s and 1990s.
Although Ackroyd was convicted of only one murder, investigators and journalists later uncovered substantial evidence linking him to several other killings and disappearances. His position as a highway worker gave him intimate knowledge of isolated roads, campgrounds, and forest routes, locations that repeatedly appeared in investigations connected to him. Many of his suspected victims were young women who disappeared while traveling alone or working in remote areas.
Early Criminal Behavior
Long before he became a murder suspect, Ackroyd displayed violent and predatory behavior. In 1977, he abducted and raped a woman after forcing her into his vehicle. During the attack, he drove the victim into a remote area, assaulted her, and threatened to kill her. The victim survived and provided testimony that resulted in Ackroyd's conviction.
Despite the seriousness of the crime, Ackroyd eventually returned to society and resumed employment. Over the following years, investigators would discover that several unsolved disappearances and murders occurred in areas where Ackroyd lived, worked, hunted, or frequently traveled.
The Murder of Kaye Turner
The only homicide for which Ackroyd was formally convicted involved Kaye Turner, a 35-year-old woman from Salem, Oregon. Turner disappeared in 1978 after leaving a bar with Ackroyd. Her disappearance remained unsolved for years.
Investigators later developed evidence indicating that Ackroyd had been the last known person seen with Turner. In 1990, Turner’s remains were discovered in a remote area of Marion County, Oregon. The location was near places familiar to Ackroyd through his work and recreational activities.
Following renewed investigation, Ackroyd was charged with Turner's murder. In 2013, he was convicted and sentenced to life imprisonment. The conviction established him as a murderer, but authorities continued examining his potential involvement in additional crimes.
Connection to the Disappearance of Cathryn Wilson
One of the most significant cases associated with Ackroyd involved Cathryn Wilson, a 19-year-old college student. Wilson disappeared while hitchhiking from Oregon to visit her boyfriend in California during August 1986.
Witnesses reported seeing Wilson accept a ride from a man driving a pickup truck matching a vehicle associated with Ackroyd. Investigators later determined that Ackroyd had been traveling in the area at the time of her disappearance.
In 1993, Wilson's remains were discovered in a remote area near Highway 20 in Oregon. Evidence and witness statements increasingly pointed toward Ackroyd, though prosecutors never obtained enough evidence to file murder charges before his death.
The Murder of Rachanda Pickle
Another case frequently linked to Ackroyd was the disappearance and murder of Rachanda Pickle, a 13-year-old girl who vanished from Sweet Home, Oregon, on July 26, 1990.
Pickle's body was found several weeks later in a wooded area. The crime shocked the local community and remained unsolved for many years. Investigators eventually identified connections between Ackroyd and locations associated with the case. Reports indicated that Ackroyd had knowledge of the area where the victim's body was discovered and had been present in the region during the relevant period.
Although investigators considered him a strong suspect, no charges were filed in connection with Pickle's murder before Ackroyd died.
Suspected Involvement in Additional Crimes
As investigators reviewed Ackroyd's history, they discovered a pattern of violence, sexual predation, and suspicious connections to unsolved cases. Several disappearances occurred near Oregon highways where he worked or frequently traveled. Witness statements, behavioral similarities, geographic patterns, and circumstantial evidence caused authorities to consider him a suspect in multiple additional crimes.
Because many of the cases were decades old and lacked forensic evidence, investigators faced significant challenges in securing criminal charges. Nevertheless, law enforcement officials publicly stated that Ackroyd remained a suspect in numerous unsolved homicides and disappearances throughout Oregon.

Investigation and Public Attention
For many years, Ackroyd escaped serious scrutiny despite his violent criminal history. Renewed investigations by law enforcement and extensive reporting by journalists eventually brought attention to the possibility that he had committed additional murders beyond the one for which he was convicted.
Investigators noted that Ackroyd often hunted in remote forests, possessed extensive knowledge of isolated terrain, and spent much of his career traveling Oregon's highways. These factors gave him opportunities to encounter vulnerable victims and conceal evidence in locations difficult for authorities to search.
Conviction and Imprisonment
In 2013, Ackroyd was convicted of murdering Kaye Turner and sentenced to life in prison. By that time, he was already regarded by many investigators as a likely serial offender. While incarcerated, authorities continued examining cold cases potentially connected to him.
Ackroyd maintained his innocence regarding murder allegations. However, investigators remained convinced that he had committed crimes beyond the single homicide for which he was convicted.
Death
John Arthur Ackroyd died on June 30, 2016, while serving his life sentence in an Oregon prison. His death ended the possibility of future prosecutions related to the numerous unsolved cases in which he was a suspect.
Although only one murder conviction was obtained, many investigators believe Ackroyd was responsible for multiple killings and disappearances spanning several decades. His case remains one of Oregon's most significant serial murder investigations, and several crimes associated with him continue to be examined by law enforcement agencies.
Legacy
John Arthur Ackroyd is remembered as a convicted murderer whose crimes extended far beyond the single homicide proven in court. Evidence gathered over decades connected him to several disappearances and killings of young women and girls in Oregon. His case highlights how violent offenders can evade detection for years and how cold-case investigations can uncover patterns linking crimes that initially appeared unrelated. Even after his death, investigators and victims' families continue seeking answers regarding the full extent of his crimes.
