(Portland, OR) -- Human remains found in a sunken car at Cascade Locks have been confirmed to be a Portland family that went missing just before Christmas in 1958. The Oregon State Medical Examiner confirms the remains are Kenneth, Barbara and Barbie Martin. The bodies of two daughters were found downstream months after the disappearance, but the parents and oldest daughter were never found. The medical examiner partnered with a forensic genetics lab specializing in advanced DNA analysis to complete the identification.
