Authorities plan to release an update on the investigation into the 1971 disappearance of two South Dakota girls.
Authorities are holding a news conference Tuesday afternoon to discuss results from forensic testing on human remains found last September in an upside down Studebaker pulled from a creek. Record flooding followed by a drought brought the vehicle into view.
Cheryl Miller and Pamella Jackson, of Vermillion, were last seen in the car on their way to a party in May 1971.
South Dakota Attorney General Marty Jackley earlier said a mechanical test points away from foul play because the car was in third gear, the highest.
A forensic pathologist confirmed skeletal remains found in the car are consistent with being from two different people.
