A taxi driver whose bad temper led him to brutally stab his mother-in-law to death was jailed for life yesterday. Mr Justice Michael Stuart-Moore told Wan Tak: 'This attack reveals you to be a most vicious killer with a temper that has a dangerously short fuse.' Wan, 28, liked his mother-in-law but thrust a Gurkha knife into Lu Lin more than 60 times in a state of 'blind rage', the judge said. The driver has previous convictions for assault, and admitted beating his wife when he caught her half naked with another man. Wan, who was found guilty of murder, showed no emotion as he left the High Court for the cells. He had admitted manslaughter but denied murder, claiming the 46-year-old victim had provoked him into killing her. His wife, Chin Yu, ended their relationship because of his violence towards her, the judge said. Wan visited Lu, a former soldier in the People's Liberation Army, because she wanted to negotiate the return of some of her daughter's property. The judge said the taxi driver had now tried to put the killing out of his mind by claiming he could remember nothing about it. The jury had been spared seeing photographs of Lu's butchered body, which 'revealed the full horror of what you did to that lady', Mr Justice Stuart-Moore said. Wan claimed he ended the marriage when he found out his wife was working as a prostitute. Questioned by Robert Forrest, defending, he told the jury he snapped when his mother-in-law accused him of driving his wife into prostitution. Prosecutor John McMaster said Lu was repeatedly stabbed in the upper body. One wound, to her back, penetrated deep into her lung. There was also evidence that her arms had been tightly gripped while she was being stabbed. Wan was arrested after one of his wife's friends called at the flat moments after the murder. When she went to fetch the caretaker, he wrapped the body in a sheet and dumped it in a telephone exchange room two floors below. Police arrived to find him trying to mop up blood in the flat.
