A MAN on trial in the High Court for murder said he would adopt an affidavit by his co-defendant which stated he had nothing to do with the killing of his air hostess girlfriend. Patrick Wong denied he had any part in killing Miss Brenda Wong Tze-kwan or helping to dispose of her body. He said: ''If I were to dispose of the body, I would have dumped it in the hills. Why was there a need to keep it in my flat?'' Questioned by his counsel, Mr Kumar Ramanathan, Wong said he became aware of an affirmation by his co-defendant Kitty Yu Mo-ling in which she stated he had nothing to do with the killing. Both Wong and Yu were convicted by a jury at an earlier trial. Wong said he became aware of Yu's affirmation after he filed his appeal. The couple are being re-tried before Mr Justice Duffy and a jury. Wong, 36, an American citizen and Yu, 30, have denied the murder of Miss Wong, 28, a senior purser with Cathay Pacific in May 1989. Miss Wong's body was wrapped in plastic food film and put in a trunk into which caustic soda was poured. It is the Crown case that Miss Wong left her flat on May 6, 1989, after receiving a telephone call and was not seen again. When asked if he knew if she had come to his flat that morning, Wong said he did not know. When questioned about May 12, the defendant said he was woken up and was brushing his teeth when he heard voices outside. A police officer kicked open the main door and said they had received information that there were drugs in the flat. Wong said he told them that all the drugs were on the table and that he had nothing more. He was taken to the second floor where he saw more officers with Yu. Wong was taken to the bathroom on the second floor where there was an aluminium trunk with smoke coming out of it. An officer asked him if the trunk contained drugs. Wong said all the cocaine he had was on the table as he had pointed out to them earlier. The trunk was opened by an officer using pliers and a long pole. Wong was then asked what the contents were. ''I kept making guesses saying it could be the dog. Then the officer stirred the contents with a crowbar. He stirred it for quite some time and eventually I saw him stir up something - it appeared to be a human skull,'' Wong said. Speaking through an interpreter he said: ''I was very confused and did not know what to say in reply. I was thinking a lot of things in my mind.'' The hearing continues.
