Detectives finally discovered the fate of the remaining family members who vanished in their car almost 70 years ago on their way to find Christmas decorations in Oregon.
The Hood River County Sheriff's Office announced Thursday that Kenneth, Barbara and Barbie Martin had been identified from human remains found in the Columbia River.
The sheriff's office finally concluded its decades-long investigation and, despite speculation, 'found no evidence of a crime.'
'The Martin family originally disappeared in December of 1958 while reportedly visiting the Columbia River Gorge to collect Christmas greenery,' read their statement on social media.
'The remains of Virginia and Susan Martin were found downstream months later, but the parents, Kenneth and Barbara, and oldest daughter Barbara (Barbie) were never found despite extensive searching and diving.'
A Ford station wagon believed to be the Martins' was discovered in the Columbia River in 2024 by independent diver Archer Mayo.
The car was pulled from the river in 2025 with human remains in tow.
Oregon State Medical Examiner's Office used DNA extracts from the remains and a profile of the Martin family's relatives to confirm their identity.
The eldest daughter, Barbara's, body was never found, but her younger sisters, Virginia and Susan, were discovered floating in the river months after the family disappeared.
The family had gone to the Columbia River Gorge to collect Christmas decorations.
'This identification reflects a sustained coordinated effort, scientific partnership, and continued advancements in forensic genetic genealogy,' read the Oregon State Medical Examiner's statement.
The medical examiner's office had the help of the forensic genetics lab Ortham Inc, which specializes in processing evidence from cold cases.
The company's Chief Development Officer, Kristen Mittelman, told KATU this was a years-long process.
'So many people worked for years to find and identify the Martin family and we are proud to have helped,' she said.
'A mystery like this doesn't just weigh on the family; it weighs on the entire community and hopefully this gives a lot of people the resolution they deserve.'
It is a bittersweet ending to a cold case that had gripped the nation for the better part of 60 years.
The Martins were reported missing on December 9, 1958, after the parents failed to show up for work.
In 2024, an independent diver located the potential car the family was driving when they disappeared in the Columbia River.
Rumors swirled for decades about what happened to the Martins, but no suspects were ever named in the case.
Upon initial investigations, authorities believed their car had accidentally backed into the Columbia River.
Barbara, Virginia and Susan were just 14, 13 and 11, respectively.
But many, including the family's eldest son, Donald, suspect foul play.
The then-28-year-old, who was living in New York at the time, told detectives that he couldn't see how his parents' and sisters' deaths were an accident.
Detectives even offered a $1,000 reward for those who could offer information.
A month after their disappearance, a gun was found near where the Martins vanished.
The sheriff's office didn't collect it as evidence, but decades later, the gun owner's widow told local news that it had dried blood on it.
An autopsy report in 1959 cited a potential gunshot wound to the head for at least one of the daughters. The Medical Examiner had disputed the wound as a result of decomposition.
No suspects were ever named in the case.
The remaining three family members' bodies were identified after human remains were extracted from the alleged crash site.
Donald Martin, the family's eldest son, was 28 and living in New York when the Martins vanished.
Human remains were found in the Martins' car, which was lifted from the Columbia River in 2025.
Independent diver Archer Mayo spent several years searching for evidence and eventually led police to the car.
But diver Mayo, who spent years searching for the family in the Columbia River, believed their disappearance was simply the result of a tragic accident.
'I think that they turned around in such a way that they kind of got stuck against a curb, put the car in reverse, and it wouldn't move, it wouldn't move, it wouldn't move,' he told KATU.
'And then all of a sudden jolted and it went backwards in an uncontrollable way into the water, and that's what they all do.'
'So, yeah, I have a theory,' he added. 'I mean, no one's ever going to know if it's right or not.'
