information leading to an arrest for the murders was increased to $250,000, and this was later increased to $500,000 in September 1989 and then to $1,000,000 in March 2008. The committal hearing to determine if von Einem should stand trial for the murders of Barnes and Langley began on 5 March 1990 before magistrate David Gurry. von Einem pleaded not guilty to both murders, and his defence counsel (now consisting of barrister Mark Griffin with assistance from Marie Shaw) immediately claimed that it would be an abuse of justice for their client if he was ordered to stand trial given the mass coverage of the murders in the media in the past year. The prosecution was led again by Brian Martin QC, who was assisted this time by Tom Birchall, and their case against von Einem relied on evidence of the Kelvin murder, with the details of the crime being so strikingly similar to the murders of Barnes and Langley. The prosecution's case also relied on evidence given by former associates testifying to von Einem picking up boys hitchhiking and sexually abusing them, as well as "Mr B"'s sensational evidence being in the company of Barnes and von Einem at the time just before Barnes's murder. "Mr B" also gave startling allegations of von Einem being involved in the unexplained Beaumont children disappearance in 1966, as well as the disappearance of two girls at the Adelaide Oval in 1973. However, it turned out to be impossible to corroborate these allegations. Another witness also came forward to claim he had seen von Einem and Barnes drinking together in the weeks before Barnes's death. Also entered as evidence were samples taken from Barnes's body which showed that sedative drugs had been present. Little evidence was presented for the murder of Langley, as prosecutors felt if they could prove that von Einem had murdered Barnes, then it would naturally follow that he had murdered Langley, as well. On 11 May 1990, Magistrate Gurry ordered von Einem to stand trial for the two murders of Barnes and Langley. von Einem's defence counsel appealed the decision, launching an abuse of process action in the Supreme Court of South Australia to achieve a permanent stay of proceedings, as well as stating that the huge media interest in the charges would result in their client not getting a fair trial. Proceedings began on 19 June 1990 before
