When DeAnn Sullivan heard that a 1954 Ford had been found at the bottom of the Columbia River, her first thought was of her late mother. Ann Sullivan, who died in 2008 at 89, spent years thinking about what happened to a Portland family that disappeared on Dec. 7, 1958. On that day, Kenneth and Barbara Martin and their three daughters climbed into the family car and drove off into the Columbia River Gorge to collect Christmas greenery. They never came back.
