Skeletal Remains Could Crack 1971 Case An undated photo provided by the South Dakota Attorney General's Office shows a Studebaker with skeletal remains found in Brule Creek near Elk Point, S.D. Police say they believe the skeletal remains found in an old car in South Dakota belonged to two 17-year-old girls who disappeared in 1971. The presumed remains of Cheryl Miller and Pamella Jackson were discovered by a fisherman, CBS reports, and authorities lifted the vehicle from Brule Creek, near Elk Point, S.D., on Tuesday afternoon. Miller and Jackson were last seen on May 29, 1971, driving a beige 1960 Studebaker Lark on their way to a party. A 2004 search of a nearby farm turned up bones, clothing, a purse and other items but no car. Authorities have never said if those bones belonged to the girls. A man already serving a prison sentence on unrelated charges was indicted for their deaths in 2007, but the charges were dropped when it was determined a fellow inmate lied about the man confessing to him.
