This news item concerns the mysterious deaths of Dr. Gilbert Bogle and Mrs Margaret Chandler on the banks of the Lane Cove River in Sydney on 1 January 1963. The case became famous because the cause of death could not be established and because it exposed the libertarian activities of a group of left-wing intellectuals in Sydney known as the 'Sydney Push'.
The bodies of Bogle and Chandler were found in unusual circumstances. Bogle was partly covered by a carpet square while Chandler's body was covered by cardboard. Both had their clothing laid neatly over them. Conspiracy theories abounded at the time. Poisoning of some kind seemed to be the cause of death.
As recently as 2006 there has been a new theory. This theory suggested that in the early hours of the morning there was an eruption of hydrogen sulphide gas from the polluted river causing potentially lethal fumes to pool in deadly quantities at the location where the bodies were eventually found. The explanation for the strange covering of the bodies was that a passerby, not a murderer, covered Bogle and Chandler to preserve their modesty.
