A former supermarket manager responsible for the 'vicious' killing of his ex-wife was jailed for five years yesterday after a jury found she had provoked him. Or Fat-chin, 35, was cleared of murder after claiming his wife's relationship with another man made him feel he had 'lost everything'. He was found guilty of manslaughter. Mr Justice Peter Nguyen told him: 'You will probably live with this for the rest of your life. The killing was to some extent a personal tragedy for you.' Or had been 'very much in love' with his former wife, Tang Chin, 32, having courted her at school and married her in 1985, Mr Justice Nguyen said. He worked hard to provide for his family, climbing the ladder from storeman to manager at a Wellcome supermarket. But his wife accused him of not spending enough time with her and their two sons, now nine and 14. She began seeing another man and the couple divorced in 1996. Or resigned from his job in the hope of avoiding maintenance payments arising from the divorce. But instead, the failure to pay landed him two days in jail. 'The result was that you were out of a job and you did not have a family. The thought of your wife being with another man became, apparently, too much for you to handle,' the judge said. Or confronted Tang, a bank teller, in Des Voeux Road West on January 13, the Court of First Instance heard. He claimed he told her he wanted to see his sons but her response was: 'Why do you come to me? You have lost everything already. You are not fit to be a father. I don't want to see you again.' Or told the jury it was this which caused him to lose control and lash out with a knife he had intended to use on himself. 'What she said to me made me very angry at the time, very mad,' he said Mr Justice Nguyen said: 'The jury have found you were provoked before you launched that vicious attack.' Or's two sons would lack his love and guidance while he was in jail and the father may be estranged from them forever, the judge added. Andrew Raffell, defending, said the case was 'a human tragedy in all its aspects'. He added Or did not have the type of personality which would normally be regarded as dangerous. Or pleaded not guilty to murder. He had, from an early stage in the trial, accepted he was guilty of manslaughter.
