VINITA, Oklahoma - The attorney for a man accused in the 1999 deaths of an Oklahoma couple and the disappearance of two 16-year-old girls wants the mother of one of the teens to turn over notes from her own private investigation.

Attorney Gretchen Mosley requested the notes Monday during the first court appearance of 66-year-old Ronnie Dean Busick, who was arraigned on seven counts. He's charged with four counts of murder, two counts of kidnapping and one count of arson.

Authorities say Danny and Kathy Freeman of Craig County were shot to death on December 30, 1999. Their daughter, Ashley, and her friend Lauria Bible disappeared the same day and have never been found. Lauria had spent the night at the Freemans' home.

A motion filed by Mosley says notes from witness interviews conducted by Lorene Bible, Lauria's mother, could be used to question witnesses.

Investigators are still trying to find the bodies of Lauria Bible and Ashley Freeman. Busick's next hearing is scheduled for May 11th.
