A dim sum worker hacked off his amorous boss' head and disposed of her dismembered body to try to protect his wife and children, the High Court heard yesterday. Zeng Liangxin, 31, an imported labourer from China, denies murder. On the witness stand, Zeng said he killed restaurant supervisor Wong Miu-kuen, 37, accidentally after she offered him money in exchange for sex. The object of her affections said he then tried to cover his tracks to save his family from destitution. 'I did not think of anything that would happen to myself. I feared what might happen to my wife and children.' On October 30 last year, Zeng and Wong went back to his quarters over the Tai Po restaurant, the court heard. The dim sum worker said he was taken by surprise when his boss began unbuttoning her blouse as they sat and chatted on a bunk bed. When he asked what she was doing, she was said to have responded: 'Silly boy - don't you know?' and crawled onto his lap. Wong had said it did not matter that both of them were married with children, Zeng told the court. When he failed to respond to her advances, the plump restaurant manager was said to have told Zeng that he did not have to pay back some money he owed her. 'That meant if I would consent to her request to have some sexual relationship with her, that would do,' the dim sum worker said. Zeng claims to have killed Ms Wong accidentally. He said her head struck a bunk bed bar when he shoved her from his lap. When he realised she was dead, he hacked her head and torso apart with a chopper. He then divided the remains in four nylon bags and dropped them into a river. Wong's legs were dumped at a Fanling rubbish collection site the following day. He told the court he pocketed money from the dead woman's wallet because he was 'greedy'. The trial continues before Mrs Justice Verina Bokhary.
