In the United States in 1958, a car believed to belong to the Martin family, who mysteriously disappeared, was pulled from the Columbia River.

In the state of Oregon in the USA, on December 7, 1958, the five-member Martin family, who went to the mountains to collect Christmas greenery, mysteriously disappeared. The incident caused a stir at the time, and a new clue 67 years later brought the mysterious disappearance back into the spotlight. Authorities revealed that a car believed to belong to the family was found in the Columbia River. Diver Archer Mayo identified the car after seven years of research. The car, found upside down at a depth of 15 meters, was excavated with a crane after two days of digging, but the body remained in the river after breaking off. Hood River County Undersheriff Pete Hughes stated that the car’s chassis would be sent for forensic examination, saying, “Everything matches up. The color, make, and model of the car largely match that of the Martin family.” In the year of the incident, the bodies of two girls named Susan (11) and Virginia (13) were found in the Columbia River. However, no trace of the father, mother, and their 14-year-old daughter Barbara was found. At that time, the Associated Press (AP) wrote that after the disappearance, the police focused on the possibility that the “Martin family’s car may have fallen into a deserted canyon or river.” Diver Archer Mayo stumbled upon the Martin family’s disappearance while searching for a sunken research vessel in 2017, prompting him to conduct an intense investigation. Using modeling techniques to identify possible locations, Mayo found the car believed to belong to the Martin family in the Columbia River.
