Police eventually agreed that the disappearances were likely criminal. However, they rejected the idea that the cases were directly linked and instead suspected the disappearances were a result of domestic child abuse, calling in the
NSW Child Mistreatment Unit to investigate the community. • All three victims disappeared after parties in the area locally known as "The Mish", a former
Mission located on the outskirts of Bowraville. Due to these similarities, investigators moved away from the initial 'child abuse' theory, to instead focus on a single prime suspect, Thomas Jay Hart, a 25-year-old, white, local labourer. He was well known in the Aboriginal community in Bowraville and often attended the parties at The Mission. On 16 October 1991, while out on
bail awaiting trial, Hart was arrested and charged with the murder of Greenup. Despite the prosecution intending to try the cases together, Justice Badgery-Parker ruled that the trials for Clinton and Evelyn's murders had to be held separately, as the law at the time restricted the use of coincidence (aka similar fact) evidence. This meant that evidence from one case could not be used in the other, posing a significant challenge for the prosecution and shaping the course of the Bowraville proceedings. the third anniversary of the discovery of his body. Significant concerns were later raised regarding how the jury interpreted Aboriginal witnesses. After the acquittal, prosecutors did not proceed with the trial against him for the murder of Greenup. On 9 February 2004, the NSW Coroner
John Abernethy reopened the inquests into Greenup's death and the suspected death of Walker. On 10 September 2004, he recommended the man be charged afresh with Greenup's murder. As a result, he was charged again, this time for the murder of Greenup. The previous reward was $100,000, and it was only for information related to the disappearance of Walker. In 2006, due to direct activism and campaigning by the children's families, changes were made to
double jeopardy legislation in NSW opening the way for retrial of any person acquitted of a life-sentence offence if "fresh and compelling evidence" was uncovered. In October 2011, Walker's family found bones in bushland near
Macksville, New South Wales, but forensic testing indicated that they were animal remains.
Application for a retrial In 2016, the detective inspector leading the investigation made a submission to the NSW Attorney General calling for a
retrial based on new evidence. In the same month, the suspect said that he was not necessarily opposed to a retrial. In May there was a protest march by the families of the victims and their supporters calling for legislative change to the
NSW Parliament building. On 9 February 2017, police laid a murder charge against the suspect, and the NSW Attorney General applied to the Court of Criminal Appeal for a retrial. The Attorney General's application was heard by the Court of Criminal Appeal beginning on 29 November 2017. The Attorney General needed to identify "fresh and compelling" evidence in order to have the man's acquittals quashed and to obtain an order for a retrial. On 13 September 2018, the court dismissed the application, concluding that none of the evidence was "fresh and compelling" and that he therefore could not be retried for the murders. The court concluded that most of the evidence relied upon was not "fresh", because it was available to be tendered or brought forward prior to the earlier trial of the man for the murder of Greenup. The campaign for a retrial continues. ==Media==
