AN illegal immigrant killed his ''grandmother'' in a row, cut off her head and put it in a fridge, the High Court heard yesterday. Kong Lam-shing also chopped up the rest of Pang Yu-lan's body, before disposing of it, the court was told. Kong believed Pang, who was 60 and lived with his grandfather, disliked him and was going to report him to police. Rather than face being sent back to China, he killed her and took elaborate steps to dispose of her body, Senior Crown Counsel Michael Arthur said. Kong, 24, defended by Neville Saroney QC and Cliff Mok, denies murdering Pang. He filed an alibi notice six days ago, claiming he was either in a bakery or a park at the time of the killing. Opening the Crown's case before Mr Justice Ryan, Mr Arthur warned the jury there would be unsavoury and even revolting aspects to the case and they might feel squeamish. However, he asked them to put aside their revulsion and listen to the evidence dispassionately. He told them, although Kong referred to Pang as his grandmother, she was in fact just living with his grandfather. She was last seen about April 12, 1991, by a neighbour. About four days later, the neighbour saw Kong cleaning the floor of his grandfather's Shek Lei home in the early hours of the morning. He told her he was trying to get rid of a bad smell. The smell was so bad that the neighbour complained to the authorities. During a search four days later, police found Pang's head at the bottom of the fridge. No other parts of her body have been located. A pathologist, who examined the head, said it had been skinned and the jaw was broken. It was impossible to determine the cause of death. Inquiries revealed that Kong went to a Shek Lei estate clinic on April 16, 1991, complaining of a ''bleeding stomach'', which was causing him pain. He also said he was from China and had no identity card. He was admitted to hospital, where he was arrested four days later. He made several statements to the police under caution. The court heard that Kong told police it was the second time he had sneaked into Hongkong. The first time, he also stayed with his grandfather. Kong believed his grandmother hated him and intended to call police to have him arrested for being an illegal immigrant. As a result, he surrendered and was sent home to China, blaming Pang for forcing him to do so. He came back in March 1991 and, according to him, Pang was not happy to see him. Kong told police he and Pang had an argument on April 13, 1991, during which she struck him on the shoulder. When he retaliated, she picked up the telephone and said she would call the police. He claimed she hit and kicked him, so he fetched a knife and chopped her several times until she stopped moving. Kong dismembered the body, after placing a quilt on the floor. He put the head in a bucket, her hands in a tank in the kitchen and her legs in the washing machine. Her torso was then wrapped in the quilt and put in the wardrobe. When his grandfather, whom Kong told police was an ''idiot'', came home, he told him Pang had returned to China. The next day, he asked his grandfather, who was in poor health, to go for a walk. While the old man was out, Kong chopped up the dead woman's arms, put them in a plastic bag, and dumped it at a rubbish heap. Kong asked a friend to take his grandfather to China the next day, before chopping up the legs and the torso into small pieces. The pieces were again put in plastic bags and discarded at a refuse collection point. Kong told police he skinned the head, then put it in the fridge. He had intended to dump it a few days later, he said in a statement. The hearing continues today.
