S hortly after noon on the 2nd of July, 1970 - Tourists at Loch Ard Gorge, in South Western Victoria, Australia, spotted a smashed motor car balanced precariouisly on a small ledge about seventy metres (150 feet) below where they stood. With only a few centimetres of crumbling limestone preventing the car from falling into the tumultous seas below, they expected the car would be lost at any moment.
A  search and rescue worker scaled the sheer cliff to examine the car in the fading light. Amongst the debris he found a loaded rifle. Even more sinister and ominous, was the smell of death that emanated from the wreck. The car was so delicately balanced, that it was decided to abandon the search for the day, until the car could be secured.
H undreds of kilometres away in suburban Melbourne, police had traced the car's registration to a triple fronted brick house - the home of the Crawford family. Police broke into that empty house and what they found sparked off one of the biggest manhunts the State of Victoria had ever seen. Splashed with blood, and the beginnings of an attempt to clean up the mess, police had walked into the most intriguing murder mystery in the modern history of Victoria, if not Australia.
The Crime remains Unsolved.
