Gilbert Stanley Bogle, born in 1924, was a physicist who worked at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) on the campus of the University of Sydney. Married with several children, he was considered to be a brilliant scientist and had been a Rhodes Scholar. The police discovered that Bogle had casual relationships with other women, some of whom he took to parks. The Coroner stood down a key female witness before she could give evidence, to protect her family and that of Bogle.
