THE family of a policewoman who died after suffering a serious head injury while riding on a colleague's motorcycle is considering seeking compensation from the hospital where she was treated. Cathy Wong Sze-wai's 42-year-old mother, Wong Wong Chung-yee, said she was making contact with a barrister through a family friend to discuss the case. ''We'll ask for legal advice on whether we have strong evidence to seek compensation,'' Mrs Wong said. Cathy, 20, died on May 30 when she fell off a police motorbike she had been riding on private land without a crash helmet. She was initially reported as being in a satisfactory condition when she was admitted to Queen Mary Hospital, but died four days later following brain surgery. On Wednesday a jury returned an open verdict on her death after a three-day hearing, during which witnesses questioned the standard of medical care she had received. A colleague, Chief Inspector David Lorimer, told the hearing that when he visited her, a drip was hanging loose from her body. But Coroner Rodney Venning told the jury there had been no evidence of a lack of care shown at the hospital. ''The family is not satisfied with the medical explanation presented in the Coroner's Court. We don't know why my daughter's condition suddenly deteriorated, or whether an earlier operation would have saved her life,'' Mrs Wong said. Although the family was considering whether to embark on a legal battle, Mrs Wong said she appreciated the difficulties involved in legal proceedings. ''I must also consider whether my health allows me to carry on. I'm exhausted these days.'' She said there were questions unresolved. ''We still have no idea as to how she died or the meaning of the open verdict. I'm really disappointed about the result.'' Mrs Wong said there was a language barrier throughout the inquest, adding that the technical terms mentioned in court were difficult to digest, even with the help of the court translator. ''I want to know the exact time when my girl fell off the bike and the time she was sent to the hospital. But we weren't given the answers to these questions,'' said Mrs Wong, who has another daughter. ''It is hard to believe my daughter would ride the motorcycle by herself. I also want to know precisely what happened.'' Mrs Wong said Cathy had long held an ambition to be a policewoman. She said what made her so enthusiastic about the job was her desire to help others. ''She was a volunteer worker in a district social welfare centre when she was a student. She often donated blood, but most of all, she was devoted to her job and carried out her duties excellently.'' Cathy was an optimistic girl who had brought her family great joy and vitality, she said. Mrs Wong described her home without Cathy as being ''spiritless''. ''She was very independent and responsible. She gave the largest amount of money to the family and planned to further her studies overseas.'' The family would seek further advice from lawyers and the Legal Aid Department, she said.
