The sister of a Filipino domestic helper whose body was found floating off Tung Chung has talked about the sense of injustice and deep loss over the death of her youngest sibling, who went overseas vowing to make her family's lives better. Vicenta Flores, 31, was seen running out of her employers' home in Discovery Bay on the night of April 7 as they returned home, police said. Her body was found floating off Tung Chung New Development Pier on the opposite side of Lantau on April 11. Police on Thursday said the death was not suspicious and a postmortem examination determined she had drowned. Her death has been the talk of residents in the gated community, which held a candle-light vigil on Friday 'to seek justice'. The victim's older sister, Irene Flores-Reguis, who worked for seven years in Hong Kong as a helper, flew from the Philippines after the body was identified by two Hong Kong-based relatives. 'Vicky said she wanted to make a change in our family's life,' Ms Reguis said. 'Our house had thatched coconut leaves for a roof and its floor was made of bamboo slats.' With her overseas earnings, her sister - the youngest of eight - was able to buy a plot and build a three-bedroom bungalow in their hometown of Taysan, Batangas province, where their widowed mother, Emiliana, 74, lives. 'Our mother has not stopped crying since we were told Vicky was missing last week. Her request to me was to do everything for my sister's sake,' Ms Reguis said. 'What our family expects is police justice for my sister. The police are the only ones who can say how she died.' The Philippine consulate has filed a request on behalf of the family for a second autopsy. Ms Reguis said the family heard the news only when a friend of Vicky's called from Discovery Bay. No calls were received from her employers, surnamed Lee, for whom Flores had worked for 12 years. 'I do not believe she committed suicide,' Ms Reguis said. 'I know my sister. She was a very strong woman.' She said her sister did not have any complaints when she last went on holiday in January. 'The only thing she told me was that the family moved to Seabee Lane last December ... I noticed she had lost weight,' Ms Reguis said. 'She also mentioned that the house had several video cams, even in her bedroom. Before she went to bed, she would put a towel over the video cam.' Her sister had planned to finish her sixth contract by May next year and start a business in the Philippines, she said. Flores' employers could not be reached for comment. 'Investigations are continuing to see if they can collect more information about the case,' a police spokeswoman said. A coroner's court would decide if an inquest should be held based on the police investigation, she added.
