A son who allegedly killed his elderly parents and dismembered their bodies with a friend made enquiries about their bank accounts and shareholdings after they died, the Court of First Instance heard this morning. Henry Chau, 31, and Tse Chun-kei, 37, face two counts of murder over the deaths of Chau Wing-ki, 65, and Siu Yuet-yee, 63, at a flat in Tai Kwok Tsui on March 1, 2013. Both defendants deny murdering the couple but Henry Chau pleaded guilty to manslaughter on the basis of diminished responsibility. The prosecution did not accept his plea. The pair also admitted two counts of preventing the lawful burial of the couple. Prosecutor Michael Arthur warned the five women and four men of the jury in his opening speech that the case was “gruesome” and “distasteful” in nature. But he told them to deal with it “dispassionately” and “do not let the evidence upset you”. He said evidence showed that Henry Chau had accessed and made enquiries about his parents’ banking facilities after they were dead. He claimed the prosecution regarded it as “the motive of the murder”. “[Henry Chau] claimed he had no financial interest in the murder,” Arthur said. “If not, it would be difficult to understand why he had to inspect his parents’ bank accounts and shares.” Arthur said Henry Chau told lies and deceived people including his elder brother, his cousin, aunt, uncle, and the police to cover up the death of his parents. He even made a short film to seek help from the public to look for his missing parents. “They were all completely false and a deception to the public at large,” Arthur said, as he claimed evidence showed the two defendants had planned the killing as early as October 2012. He said police officers found papers about missing persons under the mattress of Tse’s bed in his room in the Tai Kwok Tsui flat on March 15, 2013. The prosecution alleged the pair planned to make the couple disappear without trace after their death. The court was told Henry Chau asked his parents to help him tidy his new home at Tse’s apartment on March 1, 2013. CCTV coverage showed Henry Chau and his parents went into the flat at 11.40am that morning. Henry Chau left the building around noon that day and his parents were not seen alive again. “[The couple] must have believed they were going to inspect their son’s new flat and to help him to tidy it up,” Arthur said. “These two defendants unlawfully killed each of the deceased as part of their plan to kill them, to dismember them and boil and dispose of their body parts.” He said police officers smelt bleach and the smell of death at Tse’s apartment when the pair were arrested on March 15, 2013. Officers also found three “body bags” with human parts inside. But Tse denied he was involved in the killing of the couple when he was arrested. The trial continues this afternoon.
