Who Killed Dr Bogle and Mrs Chandler? (2006)

Who Killed Dr Bogle and Mrs Chandler? is an Australian documentary film about the mysterious deaths of Dr Gilbert Bogle and Mrs Margaret Chandler in Sydney, Australia in 1963. Although it was assumed the couple were murdered, police investigators could find or produce no evidence that it was actually murder. The documentary, directed and written by Australian documentary film maker Peter Butt, presents unique evidence to suggest the couple died from hydrogen sulphide poisoning emanating from a river.
