Details of Disappearance

Harper was last seen sometime in 1975; she was living in Potrero, California at the time. She has never been heard from again. Few details are available in her case. Harper is missing under suspicious circumstances.

Harper's fifteen-year-old daughter, Kimberly Cozart, disappeared in February 1977, approximately two years after her mother. Both were reported missing on the same day: December 15, 1995. It's unclear whether the two cases are otherwise related, but both of them remain unsolved.
