They drove in tandem to her lodgings at Darlington. Chandler returned to the Chatswood party at 2.30 a.m. but decided to depart alone, in accordance with Mrs Chandler's understood preference that she be driven home to Croydon by Bogle. The Chandlers' two children were in the care of their maternal grandparents at Granville. Bogle and Chandler left the party soon after 4 a.m. and drove to the nearby Lane Cove River, which was known as a lovers' lane. What happened next is still unclear but, several hours later, their bodies were found. At the subsequent inquest, medical evidence was given that Mrs Chandler had not had sexual intercourse. Bogle's body was discovered near Fullers Bridge by two youths searching for golf balls. They saw his body and presumed him to be drunk. When they returned an hour later to find that he had not moved and that his face had turned blue, they went to fetch help. When police arrived at the scene they discovered that Bogle's body was half-undressed. Somebody had placed his trousers over the back of his legs in such a way that he appeared to be dressed, but was not. A piece of carpet was also laid on top of his back underneath his jacket, which was laid perfectly on his back. Shortly after this, Mrs Chandler's body was discovered a short distance away. She was also in a state of undress, and her body had been covered with a broken-up cardboard beer box. It was initially believed that she had covered Bogle's body first and then her own, but closer examination suggested that someone had covered her body as well. It was obvious that both had died from some sort of poisoning. At the scene were signs of vomit and excreta. Excreta from both victims along with items of clothing were found on the exposed bed of the river. Because New Year's Day was a public holiday, forensic examination of the bodies was delayed for 36 hours. When forensic examination did take place, no traces of any poison could be found. The case attracted instant publicity. It involved a high-society party, alleged wife-swapping, an unidentified third person at the death scene, and an unidentified poison. There was also speculation that Bogle was involved in research important in the Cold War. The inquest in May 1963 did not help to resolve the mystery. The coroner, Mr. J. J. Loomes, concluded that Bogle and Chandler had died because of "...acute circulatory failure.
