Two South Dakota girls heading to an end-of-school-year party at a gravel pit in 1971 drove off a country road and into a creek where their remains lay hidden until last fall when a drought brought their car into view, authorities said Tuesday.
State and local officials confirmed Tuesday that the 1960 Studebaker unearthed in September contained the remains of Cheryl Miller and Pamella Jackson, both 17-year-olds who attended Vermillion High School.
The investigators showed dozens of photographs of well-preserved clothing, Miller’s purse and even her driver’s license complete with a smiling photograph. Those personal items and DNA were used to identify the girls, said Attorney General Marty Jackley.
Classmates who saw the teens before they disappeared and other evidence indicated that they had not been drinking, he said. In addition, mechanical tests on the car pointed away from foul play, Jackley said. He noted that the car was in the highest gear and the headlight switch on the dashboard showed the lights were on.
“It’s consistent with a car accident,” Jackley said.
Family members, law enforcement and others had searched the area countless times without luck.
“They were searching and they simply didn’t find it,” Jackley said.
Jackson’s father, Oscar, died Sept. 18, five days before the car was found.
“If you look at that obituary, it indicates one of the saddest parts of Oscar’s life is not knowing about the disappearance of his daughter Pam,” Jackley said.
The girls’ disappearance was one of the initial investigations of South Dakota’s cold case unit in 2004.
A September 2004 search of a Union County farm turned up apparently unrelated bones, clothing, a purse, photographs, newspaper articles and other items, but not the car.
In a warrant authorizing the search, authorities said David Lykken, who lived at the farm in 1971 and was a classmate of the girls, might have been involved in their disappearance. Lykken is in prison serving an unrelated 227-year sentence for rape and kidnapping.
In July 2007, a Union County grand jury indicted Lykken on murder charges in the disappearance of Miller and Jackson. But state prosecutors dropped those charges after concluding that a jailhouse informant lied when he said Lykken admitted to killing the teens.
Attorney Mike Butler, who represented Lykken, said the state has yet to apologize to the family for the search and allegations that turned out to be false.
“This whole thing with a man being charged, the Lykken family farm being plowed under,” Butler said of the search. “That family suffered needlessly for a long time.”
