The family of a grandmother who appeared to vanish without a trace are now following a series of clues after discovering a chilling handwritten message left on a notepad.
Colleen South, 58, went missing after driving her 2006 Hyundai Getz from the South Australian suburb of Renown Park to Wyncheproof in rural Victoria on July 1.
The car was found abandoned having crashed into a ditch just two days later, but Colleen was nowhere to be seen.
