A man accused of murder cut his own face and arms with a saw before placing the implement in his dead victim's hand, according to a document tendered to Wollongong Local Court yesterday.The accusation was contained in police facts tendered in the case of Darren John Vickery, who applied for bail charged with accessory after the fact to murder.Police have accused Vickery of lying about the killing that occurred in his former home in Myuna Way, Mangerton, in November last year.Vickery's former flatmate, Reece Beldon has been charged with the murder of a 37-year-old Canberra man who was stabbed to death.The police facts said Vickery initially said Beldon had acted in self-defence, killing a stranger who broke into their unit in the middle of the night, armed with a saw.However, on Tuesday Vickery had told police he and Beldon knew the deceased man and Beldon had killed him following an argument over drugs.Vickery had told police Beldon had injured his face and arms with a saw after the Canberra man had been stabbed with a kitchen knife.Beldon had then placed the saw in the dead man's hand to make it appear that the killing was in self-defence.Police investigations since November revealed that Beldon and Vickery knew the Canberra man and had spent the afternoon before his death with him.The police facts said Beldon and Vickery had both shown signs of dependency on OxyContin, a prescription painkiller, and had been banned from some doctors' surgeries.On the afternoon before the alleged murder, the Canberra man had been seen at a doctor's surgery from which the two accused men had been previously banned for "doctor shopping".The Canberra man had been given a prescription for OxyContin, which Vickery later bought from him.Vickery had told police on Tuesday that the Canberra man returned to the Myuna Way unit about 6.30pm on November 27, where Beldon, Vickery and their alleged victim manipulated and injected the OxyContin.About 2am, Beldon and the Canberra man had got into a loud argument about Valium which had also been bought the previous afternoon but had gone missing.The argument allegedly resulted in Beldon stabbing the man in the face and back.Police have also accused Vickery of disposing of evidence in an industrial waste bin following the killing.Magistrate Paul Johnson refused to grant bail.Vickery, 45, of Princes Hwy, Fairy Meadow, is due back in court on May 13.Beldon, 34, of Mangerton, is due back in court on June 24.
