Australia's Strangest Mysteries #2

Nearby, in a ditch,lay Mrs Chandler - her face and torso bafflingly blanketed in beer cartons. The discovery made international headlines. It swiftly emerged that Dr Bogle, a brilliant specialist in solid state physics, had recently accepted a research post in Washington – and had been preparing to fly there, with his wife and children.

There were no signs of violence: no smothering or strangulation; no hypodermic marks; no evidence, in the body tissues, of poisons, or radioactive substances of any kind.
