lost in the 1974 Brisbane flood. It is also possible that Brown, who had unrestricted access to government buildings, may have destroyed his own files. Although there is no proof that he had ever visited Adelaide, a witness recalled having a conversation with Brown in which he mentioned having seen the Adelaide Festival Centre nearing completion, which would place him in the city shortly before the Oval abduction on 25 August 1973. However, no evidence has ever been found to connect Brown with Adelaide in 1966. Brown was 53 at the time of the Beaumont disappearance, which does not match the description of the suspect seen with the children, who was reported as being in his thirties. James Ryan O'Neill James O'Neill (born 1947), who in 1975 was sentenced to life imprisonment for the murder of a nine-year-old boy in Tasmania, is reported to have previously told a Kimberley station owner and several other acquaintances that he was responsible for the Beaumont disappearances. In 2006, O'Neill lost an injunction in the High Court of Australia to stop the broadcast of an ABC documentary, The Fishermen, which attempted to link him to the Beaumont case. Former Victorian detective Gordon Davie spent three years speaking to O'Neill to win his confidence before filming him for the documentary. Davie said that although there was no evidence to link O'Neill to the Beaumont case, he was persuaded that O'Neill was to blame. "I asked him about the Beaumonts and he said: 'I couldn't have done it. I was in Melbourne at that time.' That is not a denial." Later asked again if he had murdered the children, O'Neill replied, "Look, on legal advice I am not going to say where I was or when I was there." Although O'Neill claims never to have visited Adelaide, his work in the opal industry at the time required that he frequently visit Coober Pedy, which would have required him to pass through Adelaide. Davie also suspected O'Neill was involved in the Adelaide Oval abductions. The South Australia Police have interviewed O'Neill and discounted him as a suspect in the Beaumont case. Derek Ernest Percy Derek Percy (1948–2013), a convicted child killer and Victoria's then-longest-serving prisoner, was suggested in a 2007 article in Melbourne's The Age as a suspect in the Beaumont case. The Age alleged that evidence gathered by cold-case investigators indicated that Percy was a likely
