A CORONIAL inquest into the horrific deaths of two nurses is expected to find that the inquiry was hindered by witnesses who may have lied under oath. State Coroner Michael Barnes today will hand down his findings into the rape and murder of Sydney nurses Lorraine Wilson, 20, and Wendy Evans, 18, in Toowoomba in 1974. It is believed that Craig Chowdhury, Counsel Assisting the Coroner, will recommend that there is insufficient evidence to support charges against any surviving persons of interest. However, it is believed Mr Barnes will take aim at some of the witnesses at the inquiry because he has concerns about whether they were telling the whole truth but will not refer them to the Office of the Director of Public Prosecutions for perjury. THE SHOCKING STORY: Murder of Lorraine Wilson and Wendy Evans Some of the witnesses who could provide crucial evidence have injuries that would affect their memory or have been long-term drug abusers. It is understood Mr Barnes believes some of the witnesses held back key information. Four suspects, Allan Laurie, Wayne Hilton, Donald Laurie and Larry Charles, have died. Those described as persons of interest, Allan Neil Laurie, 63, Terrance O'Neill, 61, and Desmond Roy Hilton, 63, denied any involvement and their lawyers contested the admissibly of evidence at the inquiry on the basis it was hearsay. The inquest heard horrific testimony about the final days of the nurses, who were holidaying from Sydney. The inquest was told they hitchhiked to Goondiwindi to pick up Ms Wilson's Volkswagen, which had broken down. While thumbing it on the Brisbane-Ipswich Highway on October 6, 1974, they got into a car. It was the mistake that cost them their lives. That Sunday the women were taken to a party in Toowoomba. One witness told the inquest that in 1978, Larry Charles wept when he told him about the shocking crime. "He said it was two years ago today that the Murphys Creek ladies were killed and he was there," the witness told the inquest. Charles, who later killed himself, told the witness that when the nurses refused to have sex, one of the women was punched and the other fled, screaming. The woman was hunted down, the inquest was told. Both were raped, tied up and bashed to death the next day with sticks. The women at times asked members of the public for help but they were ignored. Another witness told police several years ago that she had been told intimate details of the murders but when questioned at the inquest she said she could not remember anything. Originally she told police that a woman in a pub had given her significant details about the murders. The findings will be Mr Barnes's second last matter before he retires as State Coroner next week.
