An elderly woman died after becoming caught up in a row over a $10 umbrella, a manslaughter jury heard yesterday. Tong Kwai-lan, 34, pleaded not guilty to causing the death of Wong Wing-mui, 74, at Shek Lei Estate, Kwai Chung, on April 2 last year. Neighbour Yeung Yung-oi, 42, told the Court of First Instance Tong had been told to hit her but the blow struck Wong instead. Ms Yeung said an argument with Tong and her husband, Wong Ping-kwai, started after she accused the couple of stealing her son's $10 umbrella. She said Mr Wong swore at her in front of her children. During the argument, Mr Wong threw about 10 umbrellas from his flat into the corridor, the court heard. 'After I had picked up the umbrella, this mad dog, Tong Kwai-lan, then dashed towards me like a mad dog . . . and then she wrestled over it with me,' Ms Yeung said. Wong Wing-mui had come out into the corridor to investigate the commotion. She asked Tong to give up the umbrella, but Ms Yeung said the accused ran over and snatched it back. The court heard Mr Wong then told Tong to 'beat her to death' and 'don't be afraid to strike her'. Ms Yeung said that Tong did as she was told. 'I was supposed to die, but the blow landed on [Wong Wing-mui] and, as a result of that, [Wong Wing-mui] died.' Pathologist Dr Lam Wai-man said although Wong Wing-mui had a serious heart condition, the fact she died within an hour of the assault meant it had precipitated her death. The trial continues before Madam Justice Clare-Marie Beeson.
