THREE kidnappers who murdered a Hong Kong businessman and his secretary in Guangdong have been sentenced to death by a Dongguan court. Martial arts master Qiao Lifu and two female accomplices, Shao Miaomiao and Yung Fengbo, were found guilty in the Dongguan People's Intermediary Court of kidnapping, robbery and murder. According to a report by the China News Service, businessman Sham Ka-yan, 41, who ran a shoe factory in Tangxia, Dongguan, was lured by Shao to a rented villa in the town on June 27. Qiao and another man, whose case will be dealt with later, threatened Sham with hunting rifles and daggers, forcing him to promise an $800,000 ransom. Sham's secretary and business associate in Hong Kong, Chan Kit-man, 35, took the money to Shenzhen the following day to meet Shao. But she was told to take the money to the villa. It was alleged that Qiao, Yung and the second man, identified as Dong Yu, killed Sham and Chan and dismembered their bodies before dumping them in a remote part of the countryside. Their mutilated bodies were found on June 30, stuffed in plastic bags. Local businessmen who own factories in China, particularly those in Guangdong, were shocked by the brutal murders. There have been calls for increased security and protection by mainland officers. Public Security Bureau officers recovered $600,000, believed to be part of the ransom, two rifles and a car belonging to Sham. Three other people were arrested. The news service said Qiao, Shao and another mainlander, had taken part in the kidnapping of a public relations manager of a Shenzhen hotel.
