Rayney family still wondering how Corryn died a year after Lloyd Rayney was cleared of murder Lloyd and Corryn Rayney during happier times. IT has been more than six years since Corryn Rayney was murdered yet to this day her two daughters Caitlyn and Sarah, as well as the rest of her family still do not know who is responsible. This beautiful, intelligent, vivacious woman, who was a well-respected Supreme Court registrar disappeared after a boot scooting class on August 7, 2007. Tragically, her body was found buried in a shallow grave at Kings Park nine days later. Initially police had thought her husband, Lloyd, was involved. Their marriage had broken down, they were sleeping in separate rooms and on the night she disappeared the pair were meant to discuss their impending divorce. In the weeks following the discovery of her body police identified Mr Rayney as a suspect but it took more than three years before they charged him with murder. Last November Mr Rayney was acquitted following a three-month judge only trial. A subsequent appeal by the state against the verdict was dismissed in September this year with the three appeal judges upholding former Northern Territory chief justice Brian Martin's original verdict that Mr Rayney was not guilty. Then last month the state revealed it would not seek to appeal the decision in the High Court, therefore dropping further legal challenges. One of the main failings in the prosecution case highlighted by Justice Martin in his verdict was not only did the state fail to prove its own case but it failed to disprove an alternative scenario. Justice Martin found Mrs Rayney was attacked outside her home. He also said it was possible Mrs Rayney was the victim of a sexually motivated attack which may suggest more than one person being involved. Lloyd Rayney leaves court during his trial. What exactly happened to Corryn Rayney in the hours after she left her boot scooting class in Bentley still remains a mystery. Fellow boot scooters testified that she left at the usual time and according to Mr Rayney was expected to be home by 9.30/9.45pm to meet up to discuss their impending divorce. Their eldest daughter Caitlyn was at a Gwen Stefani concert and was expected home around the same time but didn't arrive until 10.45pm that night. But Mrs Rayney never made it through her front door. Justice Martin found Mrs Rayney did drive home and that she was attacked outside the front of the house or on the verge based on the forensic evidence. Tests on two seed pods found in Mrs Rayney's hair were confirmed as coming from liquidambar trees in Como. And they way in which these prickly golf ball sized pods were positioned - they were found at the back of her head - as well as the soil found in her hair led the judge to conclude Mrs Rayney was knocked to the ground and involved in a struggle. Material such as soil and brick and paint fragments found on her boots, clothing and body also came from Como and her injuries - a blow to the back of her head and damage to the discs in her spine - were consistent with being attacked from behind. No one heard any noises coming from the Rayney home the night she disappeared and Justice Martin said it was possible the Supreme Court registrar was unable to cry out for help or defend herself because she was attacked from behind. He said it was then possible that she could have been the victim of a sexually motivated attack. The evidence did not exclude this theory and the state did not disprove it either. Adding weight to this alternative scenario was the discovery Mrs Rayney's fly was undone, the zipper stuck, her belt removed and her boots taken off. Her shirt had been torn and pushed up beyond the level of her bra and saliva had been found on her neck and the entrance to her vagina. One of the police officers involved in the case testified investigators did consider she might have been the victim of a sexual assault but said it was only considered at the start of the murder inquiry. And a pathologist who conducted the post mortem examination also conceded that Mrs Rayney could have been the victim of a sexual assault. All of these factors led Justice Martin to offer this alternative theory and was scathing of the state in its inability to disprove it. An exhibit shown at Lloyd Rayney's trial last year: Corryn Rayney's car parked on Kershaw Street in Subiaco. Corryn Rayney's car was used to transport her unconscious body to Kings Park before she was buried in a shallow grave. After she was attacked the silver Ford Fairmont was abandoned in Kershaw St, Subiaco after it began losing power. The attacker had driven over a bollard causing transmission fluid to leak. The discovery of the car on August 14, 2007 and the subsequent leak led investigators to Mrs Rayney's bush grave. A thorough examination of the vehicle uncovered no fingerprints on the outside of the car but dozens were found inside. 120 people connected to the family were fingerprinted and were eliminated leaving 26 unidentified prints. These prints were found on a David Jones bag and a street directory in the rear of Mrs Rayney's car. They were also found on the right rear window, left rear quarter window, left rear window, right rear door handle, front left door armrest and a CD in the CD unit. To date those fingerprints have yet to be identified. Orange fabric A piece of orange fabric belonging to Mrs Rayney's shirt was also found among debris in the back seat which Mr Rayney's defence team suggested pointed to an attack. They also claimed an unidentified dirt footprint located on the rear middle console pointed to the involvement of another person. During the trial a written statement from an RAC patrolman was read out which said he saw two or three people "pushing or shoving" in one of two cars travelling in convoy on Albany Highway on the night Mrs Rayney disappeared. This evidence was not explored during the trial. A former police officer also testified he saw a woman matching Mrs Rayney's description with friends in Victoria Park the night she disappeared. But Justice Martin later dismissed this saying if she had been out with friends they would have come forward. Forensic officers conduct investigations in King's Park in connection with the disappearance of Corryn Rayney. During the trial it emerged fibres uncovered along the path to the gravesite, in the grave, in Mrs Rayney's car and on her shirt did not match any samples taken from the Rayney's Como home. Justice Martin said it was not surprising that fibres from the gravesite were found on the deceased's shirt and that it was also not surprising the area of the gravesite would produce fibres that did not correspond with any other fibres. But he did think it was "of note" that a fibre found along the entry path matched a fibre found from vacuumings from the driver's seat of Mrs Rayney's car. This fibre did not match any fibre linked to Mr or Mrs Rayney. Mr Rayney's defence team suggested that not only did the fibre evidence not implicate Mr Rayney it suggested the involvement of another person. Police investigators arriving at court during Lloyd Rayney's trial. After being attacked outside her home Corryn Rayney was driven to Kings Park and buried. A post-mortem examination revealed she took her last breaths near the gravesite quashing the state's contention that Mrs Rayney was killed in Como. Besides unidentified fibres being found near the gravesite, DNA was also found on a branch on top of the grave. Testing confirmed it did not come from Mr or Mrs Rayney and appeared to be a mixture of at least two people. A blonde hair was also found in leaf litter within the gravesite but no DNA testing was carried out. DNA that didn't belong to Mrs Rayney was found on her credit cards in car as well as the CD button. A mixed DNA profile was also found on her wallet and the street directory. A cigarette butt found on the verge outside the Rayneys' Como home contained DNA from a man who had been pulled over by police in the vicinity of the Rayney home on the night Mrs Rayney disappeared. During the trial it also emerged this man had lived in the area with one of WA's worst sex offenders who now lives in Victoria. A forensic scientist told the trial a full DNA profile was found on the butt which he said also had not been on the verge "for a great deal of time." But no specific time frame was given and Justice Martin made no mention of it in his judgment.
