Remains found in a Columbia River car closed a mystery that haunted Oregon for nearly seven decades.
CASCADE LOCKS, Ore. — Oregon officials said Thursday that DNA testing identified three people whose remains were found in a car in the Columbia River as members of the Martin family, closing one of the Pacific Northwest’s longest-running missing-family mysteries nearly 68 years after they vanished.
The announcement identified Kenneth Martin, 54, Barbara Martin, 48, and their daughter Barbara “Barbie” Martin, 14, whose family disappeared on Dec. 7, 1958, during a trip from Portland into the Columbia River Gorge. It also moved the case from a long-unsolved disappearance into a largely answered recovery, even as officials said the family’s exact final moments inside the station wagon may never be fully known.
The Martin family left Portland on a Sunday in early December 1958 with plans to gather Christmas greenery in the gorge. With Kenneth and Barbara were their daughters Barbie, 14, Virginia, 13, and Susan, 11. Older news accounts said the family left in such an ordinary rush that newspaper comics were still spread around the house and chores were left unfinished. Investigators later fixed on one firm clue: Kenneth Martin used a credit card to buy gas near Cascade Locks, about 40 miles east of Portland. A reported sighting at a snack bar farther east placed the family in the gorge near sunset, but after that the trail disappeared. Months later, searchers found Susan’s body in a Columbia River slough near Camas, Washington. Virginia’s body was found the next day upstream. Kenneth, Barbara and Barbie were never recovered, and the family’s station wagon seemed to vanish with them.
The break that changed the case came decades later from a private diver who refused to let the story go. In 2024, Archer Mayo located what he believed was the Martin family’s 1954 Ford station wagon in a catch-basin area inside the original locks at Cascade Locks. Mayo has said he spent years working through old records, bottom contours and river conditions before zeroing in on the site. By the time crews tried to recover the wreck in early 2025, the vehicle was buried deep in sediment and rock, upside down in about 50 feet of water. A crane pulled up only the frame and attached parts because the body of the car had broken down after decades underwater. When the frame came up, Hood River County sheriff’s Deputy Pete Hughes said, “Everything matches,” referring to the make, model and color long linked to the missing family. Later in 2025, Mayo found human remains in the same area and turned them over to authorities.
From there, the case shifted from search work to laboratory work. The Oregon State Medical Examiner’s Office and the Hood River County Sheriff’s Office sent evidence to Othram, a forensic genetics lab in Texas that specializes in difficult identifications. Officials said scientists were able to develop a DNA extract from the remains and build a profile that could be compared with reference samples from known Martin relatives. That process 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 the location of the recovery and anthropological review allowed them to identify Barbara and Barbie as well. Sgt. Joel Ives, a sheriff’s office spokesperson, said the method can identify people from DNA evidence even when no direct comparison sample is available at the start. Officials said that evidence answered the main question of who was found in the wreckage. It did not settle every smaller question, including the exact movement of the car just before it entered the water.
For most of the past seven decades, the Martin case lived in Oregon as both a family tragedy and a public riddle. It drew wide news coverage at the time, and a $1,000 reward was offered for information. The disappearance fed years of speculation about foul play, a crash off a gorge road, or some other hidden event that searchers had missed. Authorities searched shorelines, backwaters and likely routes, and the case stayed alive in official files long after the first headlines faded. On the Multnomah County Sheriff’s Office cold-case page, the Martin family remained one of the region’s enduring missing-person cases even after the original investigation had gone quiet. Old reporting captured the exhaustion that settled over the search. In 1959, an Associated Press story asked where investigators should look after checking every place that “logic and fragmentary clues” seemed to point. The latest identification does not erase those years of uncertainty, but it sharply changes the story’s ending. What had long been framed as a mystery with many theories is now, at least in official terms, a river recovery with no evidence of a crime.
That conclusion is the final procedural step in the case, and it matters because it closes off the criminal path that many people once suspected. In the joint announcement, the Hood River County Sheriff’s Office said it had concluded its investigation and found no evidence of a crime. Officials said next of kin had been notified and asked for privacy, and no media contact was being offered on the family’s behalf. The agencies involved credited the identification to a long chain of public and private work that included the medical examiner, sheriff’s investigators, Othram, the Research Triangle Institute, the Oregon State Police forensic division, the Columbia Gorge Major Crimes Team and the Multnomah County Sheriff’s Office. Kristen Mittelman of Othram said cases like this weigh not only on relatives but also on the wider community, and she said she hoped the identification brought “resolution” after so many years. Mayo, speaking in local television interviews, has offered a theory that the station wagon may have backed into the water from an unprotected area near the locks, but officials have not adopted a final public reconstruction. What they have said, clearly and repeatedly, is that the recovered remains belong to the Martins and that the case is no longer open as a suspected crime.
For now, the Martin case stands in a different place than it did for most of seven decades: not as an open disappearance, but as a documented recovery and identification. Authorities have announced no further public briefings, and the family’s relatives have asked to be left in private.
