Sealed court documents used in the criminal investigation of a 1971 South Dakota cold case involving two missing Vermillion girls will be released next week.
A judge in Vermillion has granted a request from Attorney General Marty Jackley to unseal the documents but without the names of numerous reported victims of sexual assaults.
Another judge used the documents in 2004 to grant three search warrants at the boyhood home near Alcester of David Lykken, who was indicted for killing Cheryl Miller and Pamella Jackson.
Those charges were later dropped and Jackley said in April the girls died when their Studebaker drove off a gravel road and landed in a creek.
Lykken argued unsuccessfully against the release of the documents.
Jackley’s office says the redacted documents will be unsealed June 20.
