murderer's remorse questioned in court Jole Ki Ray says he got two teardrops tattooed below his right eye in prison to represent the loss suffered by two families. "Doesn't it mean you're a killer?" crown prosecutor Helen Wilson asked. I don't go out of my way to hurt people. I'm not that smart. "It means ... that day that two families lost their children," Ray said, referring to his own relatives and the family of his victim, Priscilla Perry. Ray, 32, was found guilty of murdering Ms Perry, his girlfriend's flatmate, at The Entrance on April 9, 2011, by beating her to death. At the time he was on parole for assaulting his girlfriend, and was breaching an apprehended domestic violence order by seeing her. A sentence hearing at the NSW Supreme Court on Wednesday heard that Ray covered Ms Perry's body with a mattress, cleaned up blood, and took the battery out of his mobile phone so he could not be tracked by police. Justice Robert Allan Hulme on Wednesday sentenced Ray to at least 18 years' jail, with a maximum term of 24 years, saying he had a long history of violence particularly against women. Ray attacked Ms Perry after an argument about him failing to pay rent, the court heard. "[He] exploded in rage over a combination of relatively trivial matters, at a time when Ms Perry was particularly vulnerable," Justice Hulme said. The court was told that when the verdict was handed down last month, Ray was heard by people in the courtroom to call the jury "f---ers." The official transcript recorded him as saying: "F---ing serious?" Taking the stand, Ray said he was sorry for the murder and for causing pain to his family and to Ms Perry's family. Ms Wilson asked him exactly what he was sorry for. "I'm sorry that I'm in this situation," Ray said. Ms Wilson recounted several assault cases dating back to 2001, including against his father, for which Ray said he wasn't entirely at fault. I just know I react. After his arrest in 2011, he was convicted of fighting in jail, the court heard. "You've got to defend yourself in prison," Ray said. Ray told the court he wanted to be properly rehabilitated after years of alcohol and drug abuse, which often led to violence. "You'll say, 'I want help for my problems' ... that's just something you're saying," Ms Wilson said. I'll probably overdose on drugs in the next year. I don't care. I just want to get sentenced," Ray replied. Ray's defence barrister, Robert Webb, argued his client's violence was influenced by a "frontal lobe deficiency," caused by several head injuries he suffered throughout his life. Mr Webb also said Ray showed signs of poor impulse control. None of this excuses anything ... but in some ways, it's a perfect storm. Ms Wilson said there was no evidence that Ray would be successfully rehabilitated in jail. He's a bomb waiting to go off and he will remain so on the evidence that's before your honour.
