A man facing trial for helping his former lover strangle a woman during a sexual encounter, told the court his former flame had a 'twisted desire to kill' and that he had only dug the victim's crude grave. Micheal John Duffy, 34, pleaded not guilty to murdering Colleen Deborah Ayers, 33, whose decomposed body was uncovered in a shallow grave on her parent's 25-acre Lakesland property, located near Picton, south west of Sydney. In the opening statements of Duffy's trial Crown prosecutor Elizabeth Wilkins SC told the jury, that while his former partner, Rachel Evans, had initiated the violent act, Duffy had willingly joined in. He claimed his co-accused, Evans, was the one who had a 'twisted desire to kill' and he had only helped bury Ms Ayers' body. Micheal John Duffy pleaded not guilty to killing Colleen Deborah Ayers after claiming he had only disposed of her body while his co-accused Rachel Evans was the one with a 'twisted desire to kill' Ms Wilkins told the court Evans was the one who grabbed the belt used to strangle Ms Ayers after telling a witness: 'We are going to kill her, we are going to kill her.' 'She put the belt around Ms Ayers' neck. The deceased bucked her off.' 'It was at that stage that the accused Duffy intervened and also started strangling her,' she said. 'This was Rachael Evans' idea. She was the ringleader and this accused [Duffy] joined in.' The court heard Ms Ayers had met Evans at a pub in Campbelltown only a day before she was gruesomely murdered. It is alleged on May 8, 2012, Evans and Duffy, along with a 16-year-old girl who can not be named, went to a hotel in Picton with  Ms Ayers. Evans, Duffy and Ms Ayers then proceeded to have sex with each other while the unidentified teenager filmed the act. The next day, after drinking and taking the drug ice, Ms Ayers invited the duo, along with another man, Scott Debridge, to her parents empty Lakesland property. Ms Wilkins told the court Evans and Duffy had planned to steal and sell firearms from the rural property so they could buy drugs. Courthouse: Duffy's co-accused Evans, who has plead guilty to murder,  will receive a reduced sentence for giving evidence at her former lover's trial . Later that night, after Evans had been 'cutting up' ice, she heard Duffy and Ms Ayers having sex. The 16-year-old witness said Evans became agitated and armed herself with the leather belt. The court heard Evans then entered the bedroom and started strangling the victim. It was at this point, the crown said, Duffy joined in. Ms Wilkins said once Ms Ayers was dead, Evans dragged her body into the bathroom so she could try to wash away Duffy's DNA. Meanwhile, Duffy and Debridge went to a dam on the property to dispose of the body where they dug a shallow grave and buried Ms Ayers. During his trial, Debridge claimed he tried to refuse the orders to dig the grave, however, Duffy 'bashed' him with a shovel until he continued. After Ms Ayers' body was buried the group proceeded to ransack her parents house, stealing jewellery, an Xbox and, as planned, the firearms. It is reported the group left in a maxi taxi at about 7.40am on May 10. In a chilling revelation, Evans then allegedly told the cab driver she had a 'very exhilarating night'. Ms Ayers wasn't reported missing until May 25, when her parents returned home from holidays to the Lakesland property, where their daughter's body was secretly buried. Ms Ayers' discomposed body was uncovered in a shallow grave on her parent's 25-acre Lakesland property in 2012 . Police finally caught up with Evans on May 31, after her parents spent a week wondering where their daughter could be. Evans took officers to the property and showed them where Ms Ayers was buried. She reportedly told the young witness she felt no remorse for the killing. 'I feel good. I don't feel guilty. The f***ing belt buckle snapped. When I was burying her I started hitting her with the shovel. It felt so good,' the Daily Telegraph reported. During her trial it was revealed Evans sent fan mail to infamous murderer Ivan Milat and bragged to the unidentified teen-aged witness that she would become a 'serial killer' in years to come. Evans has plead guilty to murder and Debridge to being an accessory after the fact, with both receiving discounts on their sentences for giving evidence during Duffy's continuing trial.
