His mother Helen, 52, who was born in Hong Kong and whose father was a policeman, was not available for comment at the milkshake bar she runs in Woking, Surrey, while his father Graham, 53, a millwright engineer, has declined to comment. The couple have another son who lives in Brighton. Meanwhile the parents of murder victim Sumarti Ningshi have demanded that Hong Kong executes whoever is eventually found guilty of killing her. Ahmad Kaliman, 58, was also quoted by the BBC's Indonesian language service as saying he desperately wants Hong Kong to send his daughter's body home once the investigation into her death is completed, rather than bury her in the territory. 'I appeal to the government to help repatriate my daughter,' he said. Hong Kong formally abolished the death penalty in 1993 while still a British colony and continues to operate an entirely different legal system from the rest of China, where executions are commonplace.
