it's a studebaker just found in a south dakota creek and may drive investigators to new clues as to how these two teenage girls went missing in 1971. pam jackson, on the left, and sheryl miller disappeared as they were out driving to a party. then flash forward to 2007. this man here, a convicted rapist, was charged with their murder. now the car could either clear him or help prove his guilt. a fisherman spotted this car monday, and it matches the car those two teenage girls were driving. >> it's a little surreal, honestly. just to even believe that it's all happening right outside our door. they possibly could have been there all this time. it's a little unbelievable. >> wow. joining me on the phone john holt, crime reporter. john, so this studebaker,
