SIOUX FALLS, S.D. (AP) - South Dakota's attorney general says a mechanical test points away from foul play being a factor in the 1971 disappearance of two girls whose car was found last month.
Marty Jackley says the 1960 Studebaker was in high gear. If it were in neutral, that would indicate foul play.
He also says a forensic pathologist in Sioux Falls confirmed that skeletal remains inside are consistent with being from two different people.
The bones have been sent to the University of North Texas for identification using DNA testing.
Vermillion High School students Cheryl Miller and Pamella Jackson were last seen in the car on their way to a party at a nearby gravel pit.
The car was found upside down in an embankment in Brule Creek in southeast South Dakota.
