Authorities in Oregon have finally put a name to the remains of a woman found in the Central Cascades in 1976.
She has been identified as 21-year-old Marion Vinetta Nagle McWhorter, nearly 50 years after she went missing.

McWhorter, known for years only as the “Swamp Mountain Jane Doe,” was last seen in October 1974 at a shopping mall in Tigard, Oregon.
Her remains were discovered two years later near Wolf Creek by Swamp Mountain when a moss hunter located a skull and notified law enforcement.
Additional bones and personal belongings — including Levi’s jeans, a frayed leather coat, two rings, and a clog-style shoe — were later recovered from the scene by police.
The skeletal remains were sent to the Oregon State Medical Examiner’s Office, where both a pathologist and an odontologist examined them.
However, the cause of death could not be determined because only a limited number of bones were recovered, and the case went cold.
The breakthrough came in April 2025 after a distant relative uploaded a genetic profile to genealogy website called FamilyTreeDNA.
That upload gave genealogists the chance to conduct an in-depth analysis, which eventually led them to McWhorter’s sister, Valerie Nagle, as per CBS News.
In June 2025, Oregon State Police confirmed the identification through DNA and they publicly announced the finding in September, 2025.
“This case was cold for 49 years,” Oregon State Forensic Anthropologist Hailey Collord-Stalder said in a statement.
“That means that family members lived and died without ever knowing what happened to their missing loved one. McWhorter likely did not go missing voluntarily.”

Valerie Nagle was only 11 when her sister disappeared. She says she had spent decades searching unidentified persons cases online and even submitted her own DNA to Ancestry in 2023.
“I never forgot about her,” Nagle told reporters. “I was really glad that they found me through DNA.”
Nagle also revealed that nearly 20 years after McWhorter’s disappearance, an aunt told them that Marion had called her the day she vanished, asking for a ride from the Tigard mall.
During that call, Marion mentioned that a man in a white pickup truck had offered her a ride, but she never made it home.
The Linn County Sheriff’s Office has confirmed that the investigation into the circumstances surrounding McWhorter’s death remains open.
McWhorter was the eldest of five siblings and was named after an aunt who passed away in 1940 while attending a boarding school for Indigenous children in Alaska.
According to PEOPLE, her family believes her disappearance sheds light on the wider crisis of missing Indigenous women.
