The sister of a murdered domestic helper is seeking more than $500,000 in worker's compensation from the dead woman's alleged former employer. Marites Fetalino De Cardo, 38, was found strangled in the flat of alleged employer Ho Kik-san, 67, in Granville Road, Tsim Sha Tsui, on March 8, 1997. No one has been charged with the killing. Ms Ho's son, Yeung Sai-kwong, who lived in the flat, was arrested in connection with the murder but was later released after no charges were laid, Timothy Cheung Ping-kwan, for Ms Ho, told the District Court. Ashok Sakhrani, for the victim's sister, Cielo Fetalino De Cardo, said the victim signed a contract with Ms Ho on February 18, 1997, to work for $6,600 a month, pending approval from the Immigration Department. She died before her contract was approved by the department. Mr Sakhrani told the court the victim worked from 8pm until 8am caring for Ms Ho's husband, a stroke victim, at the Prince of Wales Hospital. The victim then returned to her Jordan Road hostel to sleep until 5.30pm, when she went to clean the Granville Road flat. But Ms Ho yesterday told the court the victim had not started to work for her. 'We were told by the employment agency we had to wait until the Immigration Department approved her contract.' The victim's sister is claiming $567,840 in employee compensation. The hearing continues today before Judge Wong Hing-chun.
