South Dakota authorities say skeletal remains were found in an old Studebaker believed to be tied to the 1971 disappearance of two 17-year-old girls.
Crews lifted the rusted, mangled car from an embankment in Brule Creek near Elk Point on Tuesday afternoon.
Union County Sheriff Dan Limoges says some potential pieces of evidence have been taken from the site and will be processed.
No other information will be released until an autopsy and more testing is done and the families are told of the results.
Investigators believe the car was driven by Cheryl Miller and Pamella Jackson, who were last seen May 29, 1971, driving a beige 1960 Studebaker Lark on their way to a party.
A fisherman called authorities after noticing one of the car's wheels exposed in the creek.
