Share on Twitter The family of an Indigenous Coober Pedy elder who lives with dementia and has been missing for 11 days in remote South Australia is questioning why more is not being done to find her. Aunty Shirley Williams was last seen leaving the Coober Pedy Hospital after a check-up on 28 December and was reported missing on New Year’s Eve. The Williams clan matriarch is aged 64 by government records but nearly a decade older, according to her immediate family, who are “losing our minds” trying to find her. “We need help every day because time is running out," niece Stella Williams told SBS News.
