Introduction: Marion Vinetta Nagle was born on January 7, 1953 to Francis and Violet Nagle in Seattle, Washington. Francis Joseph Nagle was born on September 21, 1921 in Dansville, New York and Violet ‘Val’ Jackson was born on July 8, 1927 in Valdez, Alaska (she was of The Ahtna Athabascan culture, an indigenous group of people  from Alaska’s Copper River region). After serving in WWII, Francis and Val tied the knot sometime in 1945 and went on to have five children together: Marion, Richard (b. 1959), William (b. 1955), Patricia (b. 1954), and Valerie (b. 1953). Marion got married at the tender age of sixteen on November 18, 1969 in San Bernardino, California to Kenneth Michael McWhorter, who was born on November 1, 1951 in Brownwood, Texas; the couple had a daughter together named Monica Kay McWhorter (born on February 16, 1971 in San Bernardino, CA).

The Murder: the oldest of her siblings, twenty-one-year-old Marion was living an itinerant life at the time at the time she was last heard from: in late 1974, after separating from her abusive husband, she decided to hitchhike across the northern part of the US, with plans of making her way from California to Seattle then eventually ending up in Alaska. According to her sister Valerie, Marion may have been on her way to ‘The Last Frontier’ in an attempt to find work, as their grandfather lived there at the time she disappeared. In 2024 she told Oregon Live: ‘I always hoped to find her.’ According to reports, in late October 1974 McWhorter stopped in Tigard, Oregon (which is near Mountain), and on the 26th she called her aunt from a pay phone near Washington Square Mall. Valerie said her sister had hoped to stay overnight at her house that was nearby, but she said no, and claimed she had been ‘too busy’ at the time to go pick her up.

According to Valerie, Marion had actually given birth to two daughters but had given the second one up for adoption when she was sixteen and left her older one behind with her estranged husband. Nagle also made it clear that her sister didn’t just up and abandon her child, and that she was simply trying to escape from an abusive relationship: according to police reports, her husband had at one time broken her nose. After Marion disappeared Kenneth filed for divorce in July 1975; shortly after he married Deborah Kay James, who was born on August 19, 1951; the couple had three children together, two sons and Monica’s half-sister Melissa (b. 1979).

Marion’s weight was unknown at the time of her murder, but she had brown eyes and wore her brunette hair long, and she had a healed fracture on the right part of her nasal bone; she was last seen wearing a leather coat with fringe, Levi ‘s jeans (with a 29-inch inseam), and platform-style sandals with an approximately two-inch heel (one source called them a ‘clog-style shoe’) that had a single white strap with a basket weave section that was attached to the base by 5 round tacks on each side. Valerie shared with detectives that ‘their mother was an Alaskan Native from the Ahtna Athabascan people in the Copper River area in southeastern part of the state, and her oldest sister was named after their aunt who died in 1940 in an American Indian boarding school in Alaska.’

The Discovery: on the afternoon of July 24, 1976, twenty-year-old California native David Allen Shearer that had been out on the side of ‘Swamp Mountain Road’ collecting moss to sell to florist shops when he stumbled upon a skull in the woods about a mile south of US 20 in rural Sweet Home, Oregon. She had been wearing a leather coat with fringe, a leather belt adorned with a decorative phoenix made out of black and white Native American styled beadwork, two metal rings, and Levi’s jeans; a lone clog was found nearby. After their discovery the bones were transferred to the Oregon State Medical Examiner’s Office, where a pathologist and odontologist examined them.

According to Linn County District Attorney Jackson Frost, the county was ‘seeking the identity of the woman who had been described as Caucasian, between 5’5” to 5’7” tall, anywhere from 115 to 125 pounds and had medium brown hair. He further speculated that she had been dead for ‘over a year,’ had worn ‘size ten clothes,’ and was between seventeen and nineteen-years-old: ‘we’re unable to determine how long the remains have been at that place. Though foul play had not been ruled out we don’t have any specific reason to believe this person was murdered.‘ Frost went on to say his office had already received ‘numerous’ phone calls from parents of missing girls asking about their missing daughters, and about the skull said: ‘there are no teeth missing, we have that charted. The problem even in this day is that some people don’t have dental records.’

Because a limited amount of remains that were found (the skull, some teeth, and a few ‘small bones) the examinations came back undetermined: by that point a good amount of time had passed, and on top of the natural decomposition little woodland critters would have done a good job of dispersing their bones all over the area. The odontologist in charge of the dental examination noted several restorations, and per a 2010 Linn County Sheriff’s Office report, a medical examiner identified a ’wound track on her skull, which could have been caused by something similar in size to an ice pick or small caliber firearm.’ For almost fifty years the remains laid unidentified; she was referred to as the ‘Swamp Mountain Jane Doe.’

The Secret: for many years after her sister disappeared, Valerie said her aunt’s story about their last phone conversation remained consistent, until one day when she shared that Marion had told her that a strange man in a white pickup had offered to give her a ride. Nagle said that when she learned about this piece of the puzzle she: ‘started in earnest with more searching,’ including by checking databases with unidentified persons cases: ‘I remember spending a lot of time on those pages, just scrolling through and trying to look.’ … ‘I never forgot about her.

Valerie also said that her sister’s disappearance was something her parents didn’t often talk about, and she isn’t even positive that they filed a missing person’s report as the Nagle family wouldn’t have ‘known where to even begin looking’ for their daughter and didn’t attempt to organize any search effort. In 2024 The Oregonian newspaper reached out to Tigard law enforcement and requested copies of any missing persons reports filed for Marion; after looking into it, an agency spokesperson said they hadn’t come up with anything. At the time her big sister disappeared Valerie was only eleven and was living in New York state with her parents and one of her brothers, and according to her: ‘I mean, there were, you know, efforts to search, but it was limited. We didn’t have that much to go on.’

Efforts: over the years a NamUs profile (National Missing and Unidentified Persons System) was created for the ‘Swamp Mountain Jane Doe,’ and forensic techs put her information into CODIS (or the ‘Combined DNA Index System’), which allows federal, state, and local law enforcement laboratories to digitally compare genetic samples. Forensic artists also created multiple recreations of a possible physical renderings of the victims face based on the cranial features of her skeleton as well as a clay model that even featured different hairdos and color/shade ranges that maybe she may have worn in an attempt to create an image that people who knew her may have recognized.

Updates: in 2010, the Oregon Museum of Natural and Cultural History completed an anthropology report of the still unidentified remains of the ‘Swamp Mountain Jane Doe,’ and a biological profile gave investigators demographic information on the individual, noting she was most likely a white female under 35 years old when she died. But still, she remained unidentified; also in 2010, a bone sample from the remains were sent to the University of North Texas Center for Human Identification. An additional piece of bone was submitted for DNA extraction in 2020, which allowed for a unique genetic marker profile to be produced and in 2023, Valerie Nagle submitted a DNA sample to a genealogy website when she signed up for Ancestry.com with the hope that it would result in a clue as to what happened to her sister.

It wasn’t until April 2025 that Oregon investigators got a break in the case after Marion’s first cousin uploaded their genetic profile to the Ancestry-type website ‘Family Tree DNA,’ which allowed genealogists to delve deeper into the ‘Swamp Mountain Jane Doe’s’ family tree and eventually led them to one of Marion’s surviving family members: Valerie. In June 2025 detectives reached out to Nagle ‘out of the blue’ and asked what her thoughts were when it came to Marion possibly being the ‘Swamp Mountain Jane Doe;’ she said when they contacted her she was ‘very surprised that they called. I was really glad that they found me through DNA.’ Nagle gave detectives an oral DNA swab for comparison in June 2025 which quickly confirmed that the remains belonged to Marion.

In an interview with KOIN, Oregon State Forensic Anthropologist Hailey Collord-Stalder commented that: ‘this case was cold for 49 years. That means that family members lived and died without ever knowing what happened to their missing loved one.’ She went on to add that McWhorter most ‘likely did not go missing voluntarily. This was one of our oldest unidentified cases. And I think it just goes to show you that no matter how long somebody persists in being unidentified, we won’t give up trying to identify them.’

Suspects, Ted Bundy: in October 1974, Ted Bundy was living in a rooming house in Salt Lake City and was attempting his second round of law school at the University of Utah. This period marked a notable change in his criminal activity as he was in the process of moving his ‘playground’ from the Pacific Northwest to the Intermountain West: on October 2 he abducted and killed sixteen-year-old Nancy Wilcox from Holladay, Utah, and on October 18^th seventeen-year-old Melissa Smith disappeared out of nearby Midvale; the daughter of the local police chief, Smiths remains were found nine days later. At the end of the month on Halloween night Ted abducted and killed seventeen-year-old Laura Ann Aime, who vanished after leaving a party in Lehi to buy cigarettes.

In the fall of 1974 Ted was also maintaining his long-distance relationship with Elizabeth Kloepfer in Seattle (despite also dating multiple other women) and it’s also worth mentioning that for his move from Washington to SLC he bought an old white pick-up truck at one point in time (I couldn’t find much information about that particular vehicle). I could have sworn I read somewhere that it was his brothers truck, but when I looked into it I couldn’t find much on it other than the fact that he owned it until late 1975 (this is according to the 1992 TB FBI Multiagency Report ).

John Arthur Ackroyd: a lesser discussed serial killer from the Pacific Northwest, John Arthur Ackroyd was born on October 3, 1949 in the small logging town of Sweet Home, Oregon. He was one of three kids (he had an older and younger sister), and his dad was a maintenance worker and his mother worked in the office for the Sweet Home Police Department. During his adolescence, he was considered a loner and was frequently bullied, and his high school diploma indicated that he had been in the special education program.

After Ackroyd was accused of felony theft he enlisted in the Army, where he worked overseas as a mechanic. Upon returning home in 1977, he got a job with the Oregon highway department which was located along US Route 20 and ran east to west across The Beaver State; some of his responsibilities included clearing vehicle wrecks, helping those whose cars broke down, and overall basic maintenance. Later that same year he raped twenty-nine-year-old Marlene Gabrielsen, a young mother that he allowed to live (she was the only one). In 1978, Ackroyd and an accomplice, Roger Dale Beck, he abducted and murdered thirty-five-year-old Kaye Turner, who had been out running at the time she was abducted.

At some time in the mid-1980’s he married a divorcee named Linda Pickle, who had two children from a previous relationship (Rachanda and Byron); the family moved into a house in Santiam Junction, a state highway division compound at the junction of Oregon-126, Oregon-22, and US Highway 20 (other members of the highway department lived there as well, but few of them had children). After only a year of marriage, the couple divorced but continued to live together; he was abusive to both of his former stepchildren, and Rachanda disappeared under mysterious circumstances on July 10, 1990.

By early 1992 Ackroyd had moved in with his mother in Sweet Home: because of his connection to his thirteen-year-old stepdaughter’s disappearance, most of the women and children in Santiam Junction were uncomfortable with him being there, and as a result he began to work out of Corvallis. In May 1992 nineteen-year-old Sheila Swanson and seventeen-year-old Melissa Sanders vanished while on a camping trip with Sanders’ family at Beverly Beach State Park on the central Oregon coast. They were last seen at a payphone near a grocery store on US 101, reportedly planning to hitchhike back home to Sweet Home and Lebanon. Their remains were discovered in October 1992 by hunters in a remote area off a logging road near Eddyville, and due to the advanced level of decomposition, an exact cause of death could not be determined. Ackroyd was arrested for the murder of Kaye Turner on June 12, 1992, and he was charged with Rachanda’s murder in 2013; he pleaded no contest. Lincoln County Investigators with the DA’s Office Ron Benson and Linda Snow were preparing to present evidence against Ackroyd in relation to the murders of the two young women to a grand jury when he died on December 30, 2016 at the age of sixty-seven.

Warren Leslie Forrest: logically, when I was thinking about the timing of Marion’s murder, serial rapist and murder Warren Leslie Forrest immediately popped into my head… but by late October 1974 he had already been arrested (he was taken into custody on October 2, 1974).

Richard Sean Nagle: sadly, Marion’s younger brother Richard Nagle died from suicide at the age of fourteen on March 6, 1974. He died in his home and according to his autopsy he died of ‘self-inflicted strangulation;’ per his obituary, Nagle was born in Seattle and had moved to Dansville four years prior; he was also in ninth grade at the local junior high school.

Monica & Melissa: tragically, on April 7, 2002 Marion’s daughter Monica died at the age of thirty-one along with her half-sister, twenty-two-year-old Melissa McWhorter after the vehicle they were driving was hit by a drunk driver in Moffat, Texas. Monica Kay McWhorter married Yeow B. Lim in 1996, and the couple had a son together named Jason Bravo (who fortunately survived the accident with only minor injuries). She is buried in Bell, TX.

Conclusion: the entire Nagle-McWhorter clan is steeped in absolute tragedy: Kenneth Michael McWhorter died at the age of forty-two on July 17, 1994; his widow Deborah died at the age of fifty-six on December 31, 2007. Marion’s brother William Frances Nagle died of a heroin overdose at the age of thirty-eight in Seattle on June 17, 1994. Patricia Ann Nagle-Johnson died from lung cancer at the age of forty-two on January 13, 1997 in Seattle. Marion’s father died on Christmas day in 2002 in Seattle and at the time of his death, he had been married to Violet for fifty-seven years. Violet Nagle died at the age of eighty on May 3, 2008 in Seattle from lung cancer. According to a Reddit post, in recent years Valerie was able to find the daughter that Marion gave up for adoption, but they didn’t get as close to her as they had hoped to. She currently lives in Seattle, Washington and is sixty-three years old. As of April 2026, Marion’s case remains unsolved.
