A maid drowned herself in the sea shortly after her employers' two-year-old son was found dead in a bathtub. Edna Rizardo, 34, went missing on the same day that the toddler was discovered by his mother in the bathroom of their Tsing Yi flat on February 10. The woman's body was found at Tai Pak beach, Discovery Bay, the following morning, the Coroner's Court was told yesterday. Rizardo had been told two weeks earlier that the family would be terminating her contract because they were emigrating. The boy, Li Yik-wah, had been left in the domestic helper's care by his mother, Tang Wai-tsang, when she went out in the morning. Ms Tang, 35, discovered her son motionless in the bathtub when she returned with her 11-year-old daughter. Rizardo was not in the flat. The family had enjoyed a good relationship with the maid, Senior Inspector Mak Yung-nin of Kwai Tsing police told the court. They had first hired her in June 1993 and renewed her contract for another two years in June last year. 'The father had observed the maid treated his two children well,' Mr Mak told the court. 'Once the elder daughter claimed she was assaulted for her naughty behaviour, but they couldn't find any sign of injury,' he said. 'So the parents didn't take any further action or scold the maid, fearing it might affect their relationship.' At the end of January Rizardo was given a letter stating her contract would be terminated because the family was moving to Singapore in April. 'But they said she responded to it normally,' Mr Mak said. A friend of the maid, Vivian Marcelo, told the court Rizardo did not seem to have been overly upset at the news, but she added: 'She only told me that she couldn't eat and sleep at night.' A medical report showed that the boy had died from either external interference to the neck and head or from drowning. A jury of three returned an open verdict on the boy's death and a verdict of suicide in Rizardo's case. The family is now living in Singapore and was not in court yesterday.
