Police performed an extensive search of the Southern Grampians after Rosie McClean vanished from Timboon, more than 200 kilometres south-west of Melbourne, last Thursday.
The 84-year-old’s daughter Susan McClean Graham shared the devastating news overnight that her mum had been found, but they were too late.
“Mum has been found this afternoon, unfortunately not in time,” Ms McClean Graham posted on Facebook.
“Bindi (her dog) stayed with mum until they were found and we take some comfort in that knowledge.
“Bindi will be reunited with her mate Dantai and our family in the morning.”
Ms McClean Graham thanked the people who had endeavoured to find her mother during the 11-day search.
“We are truly grateful that you all cared for our mum and Bindi,” she said.
“We thank you from the bottom of our hearts.”
The 84-year-old had left her Timboon home sometime in the afternoon on June 10.
At the time police believed she may have travelled to the Glenthompson area.
Ms McClean was last seen at her local hairdresser, with police tracking her last recorded mobile phone ping at Dunkeld at 4pm on the day she went missing, about 140 kilometres from her home.
“Police and family hold serious concerns for her welfare due to the length of time she has been missing and that she left without medication she requires,” a police statement read earlier.
