The Hood River County Sheriff’s Office says it is suspending any further recovery efforts for the remainder of a vehicle investigators likely believe belong to a Portland family who disappeared in December of 1958.  A portion of the vehicle was recovered from the Columbia River near Cascade Locks earlier this month after a private diver located it in a basin within the original lock system in Cascade Locks, upside down and buried nose first in 66 years of packed sediment and rock, about fifty feet below the surface.  Only the chassis and engine of the vehicle were recovered from the riverbed.  The Sheriff’s Office says the Martin family had a 1954 Ford 4-door station wagon, cream in color and red trim.  After comparing serial numbers with Ford Motor Company records, investigators believe what was recovered does match up with that type of vehicle, but they could not find a Vehicle Identification Number, which had just begun to be used in 1954, so they cannot say for sure it is the Martins’ car.  The Sheriff’s Office says because of the difficulties in retrieving the chassis, the corroded condition it was in, and the sediment and rock encasing the rest of the car, it does not feel expending further time or resources on pulling out the remainder of the vehicle would be prudent, so it is suspending further recovery efforts.
