CASCADE LOCKS — For the last seven years, Archer Mayo has self-funded an exhaustive research project to reconcile the record regarding the 1958 disappearance of five members of the Ken Martin family from their home in NE Portland.

Ken, his wife Barbara, and their three daughters went for a December Sunday afternoon drive to look for Christmas greens, and vanished. In the fall of 2024, Mayo found the Martins’ car hidden in an architectural anomaly under 60 feet of water and seven feet of debris in the Cascade Locks canal. The Hood River County Sheriff’s Office conducted an operation in the spring of 2025 to remove the car from the river. Several pieces were brought to the surface and are now in the possession of HRCSO.
