The finding closes one of Oregon’s longest missing-family cases nearly 68 years after the Martins vanished on a trip to gather Christmas greenery.
CASCADE LOCKS, Ore. — Oregon officials said Thursday that DNA testing identified three sets of remains found in a car in the Columbia River as members of the Martin family, nearly 68 years after the Portland family disappeared during a Sunday drive into the gorge.
The announcement identified Kenneth Martin, 54, his wife, Barbara Martin, 48, and their daughter Barbara “Barbie” Martin, 14, from remains found in the wreckage of the family car. The Hood River County Sheriff’s Office said the investigation is now concluded and that investigators found no evidence of a crime. The update matters because the Martin case had lived for decades as one of the Pacific Northwest’s most enduring missing-person mysteries, shaped by partial clues, years of searches and long-running theories that never fully explained what happened.
The Martins disappeared on Dec. 7, 1958, after leaving Portland for a day trip in the Columbia River Gorge to collect Christmas greenery. Kenneth and Barbara were traveling with three daughters, Barbie, 14, Virginia, 13, and Susan, 11. Their son Donald was not with them. Early reports said the family left in such an ordinary rush that newspaper comics were still spread around the house, dishes were left in the sink and laundry remained unfinished. Investigators later found one firm clue when Kenneth Martin used a credit card to buy gas near Cascade Locks, about 40 miles east of Portland. A waitress then reported seeing a family believed to be the Martins at the Paradise Snack Bar farther east just before sunset. According to an Associated Press story from the time, the gas purchase was “the only thing to pinpoint the family’s movements.”
After that, the trail disappeared. Five months later, Susan’s body was found in a Columbia River slough near Camas, Washington. Virginia’s body was found the next day about 25 miles upstream. Kenneth, Barbara and Barbie were never located, and the family’s 1954 Ford station wagon seemed to vanish with them. The search became national news and helped fuel years of suspicion that the case might involve something more than a crash. A $1,000 reward was offered for information. Searchers checked shorelines, river channels, roads and likely routes through the gorge, but none of those efforts produced the missing car or the rest of the family. In 1959, an AP story captured the frustration surrounding the case when it asked, “Where do you search if you’ve already searched every place logic and fragmentary clues would suggest?”
The break came decades later from Archer Mayo, a private diver who had spent years trying to find the Martin wagon. Mayo had been searching the Columbia River for other lost objects and vessels when he began digging into the Martin case and using research and modeling to narrow possible locations. In late 2024, he found what he believed was the family’s station wagon upside down in a catch-basin area within the original locks at Cascade Locks. Mayo’s representative, Ian Costello, told AP the car was about 50 feet deep and coated in mud, silt, mussel shells and salmon remains. Costello called the find “a very big development in a case that’s been on the back of Portland’s mind for 66 years.” Mayo also found other cars in the area, adding to the difficulty of proving which wreck was tied to the 1958 disappearance.
Crews tried to bring the Martin vehicle up in early March 2025 after two days of dredging and clearing mud from the site. The recovery was only a partial success. The body of the car broke apart during the lift, and only the frame and attached parts came out of the water. No human remains were found in the portion that surfaced that day. Even so, Hood River County sheriff’s Deputy Pete Hughes said investigators believed they had the right vehicle. “Everything matches,” Hughes said, pointing to the make, model and color linked for decades to the Martin family. The engine and chassis were set aside for further examination, while the buried passenger section remained below. Later in 2025, Mayo continued exploring the same area and found human remains, which he turned over to the sheriff’s office and the Oregon State Medical Examiner’s Office.
From there, the case moved from salvage work to forensic testing. Officials with the medical examiner’s office and the sheriff’s office sent evidence to Othram, a Texas laboratory that specializes in advanced DNA analysis and forensic genealogy. Despite the condition of the remains after decades underwater, scientists were able to develop a DNA extract and build a profile that could be compared with a reference sample from a Martin relative. That work allowed investigators to positively identify Kenneth Martin. Authorities said the other two sets of remains were too degraded for the same level of sequencing, but they identified Barbara and Barbie through the recovery location and anthropological review. Sgt. Joel Ives, a spokesperson for the sheriff’s office, said Othram uses an identity inference method “which allows scientists to identify individuals from DNA evidence even when no direct comparison sample is initially available.”
The identifications sharply change the meaning of a case that for years sat between accident theory and crime theory. Two daughters had been found months after the disappearance, but the absence of the parents, Barbie and the car left room for darker explanations. The Martin family stayed in cold-case files and in Oregon memory long after the original search faded from front pages. Donald Martin, who was serving in the military and living in New York state when his family disappeared, became one of the public faces of the case in early news coverage. The family’s story was told and retold because it mixed ordinary details with a vanishing that seemed impossible to explain. A winter outing, a gas stop, a diner sighting and then silence became the outline of a mystery that lasted through generations of searchers, reporters and local residents who never stopped wondering whether the family had gone into the river or been taken there.
Officials now say the evidence supports a river recovery, not a criminal case. The sheriff’s office said next of kin were notified after the identifications and asked for privacy. Authorities have not announced charges, hearings or any further criminal investigative steps, and they said they found no evidence of a crime. What remains unsettled is narrower but still important: the exact final movement of the station wagon before it entered the water. Mayo has discussed a theory that the car may have backed into the river from an unprotected area near the locks, but officials have not adopted a final public reconstruction of those last moments. That means the long central question of who was in the wreckage has now been answered, while the last few seconds of the family’s drive may remain beyond proof.
With the April 16 announcement, authorities say the Martin case is closed as an investigation and no crime was found. The largest unanswered point is the family’s exact final path into the Columbia River, a detail officials say may never be fully known.
