Updated at 6.16pm: A wife who killed her husband by pouring boiling oil over his head and stabbing him 16 times before stashing his body beneath their marital bed for three days was jailed for life on Thursday after being found guilty of murder. It was the third attempt to prosecute Li Suet-ping, 50, after two earlier juries were discharged when they were unable to cope with the horrific nature of the evidence. The seven woman, two man jury heard Sui On, 50, died after the flesh around his jaw, neck and upper chest was partially cooked when Li dumped five cattys of boiling corn oil over him. They also heard he was stabbed 16 times with a cluster of wounds found around his neck and back. He was also injected with insulin. When police found his body in a compartment beneath Li's bed three days after the murder, they discovered she had also wrapped 20 layers of plastic cling wrap around his head before covering it with a Park 'N' Shop bag. Li's defence counsel John Halley said the January 5, 2001, killing came after Li snapped following 20 years of physical and verbal abuse by her husband. During Li's testimony before the court, she said on the morning of Sui On's death, he had slapped her twice on the face, called her names, cursed her family and tried to burn her hair with a cigarette lighter after she refused to hand over $6,000. Mr Halley also said the bizarre nature of the murder was also proof that Li had not planned to kill her husband. However, prosecutor Richard Donald described the attack as deliberate and planned with forensic evidence indicating Sui On had been asleep on the family's sofa when the oil was poured over him. He also said the couple had marital problems for a number of years with Sui On, telling Li he had a younger lover. The murder had been an attempt to stop another woman taking away her husband, he said. Mr Donald also questioned Li's story that the oil was used that morning to fry a pigeon. He said she did not need five cattys to cook the small bird. During his summing up to the jury, Mr Justice Gareth Lugar-Mawson told the jury: 'If you conclude that she was provoked, then she is not guilty of murder but guilty of the lesser offence of manslaughter.'' The jury took only 75 minutes to arrive at a eight to one majority decision that Li was guilty of murder. Li's earlier two trials were discharged after gruesome crime scene photographs of Sui On's body proved too horrific. In the first few days of Li's first trial, a woman handed Mr Justice Colin Jackson a note from her doctor stating she could not continue as she had been having difficulty sleeping. In the second trial, another woman claimed she was suffering anxiety and neurosis and that further exposure to the trial could worsen her situation.
