A mother-of-six who disappeared in Tasmania more than four decades ago died from injuries inflicted by her partner who had a history of violence against women, a coroner has ruled.
Darlene Avis Geertsema, 30, was last seen at her family home in Devonport on the night of October 23, 1978.
Her red Holden was found abandoned near an oval in the northwest city a few days later.
