Updated at 4.13pm: Two women and a teenage boy were given long prison sentences in China for robbing and murdering a Hong Kong-based broadcasting executive, according to news reports on Monday. The victim was Geng Weimin, deputy-director of China Entertainment Television. Guangzhou Intermediate People?s Court on Friday convicted Wang Baozhen, 22, and 17-year-old Zhou Yun, of robbery and sentenced them to life in jail. Zhou?s cousin, 22-year-old Zhou Fangping, received 15 years imprisonment for her role, a government spokesman confirmed on Monday. The three were also ordered to pay about 310,000 yuan (HK$292,900) to the victim?s family. Geng fell victim to a scam devised by the three. Zhou Fangping used an enticing name over the internet to lure Geng to Huaan Hotel in Guangzhou on April 6 last year, the court heard. The trio then spiked his drinks. At knifepoint, they forced Geng to reveal his bank card?s pin number. Zhou went out to withdraw Geng?s money, leaving her cousin and Wang to watch over him. Wang had previously been romantically involved with Geng, Chinese media reported. When Geng attempted to call for help, 17-year-old Zhou stabbed him to death, the court heard. The victim?s family said the sentence was not severe enough. But the family of the 17-year-old said the sentence was too severe for such a young person. They said they would appeal the life sentence. The three are all from Jiangxi province. Wang and Zhou Fangping allegedly were repeat offenders, who had been operating in Fujian province before moving to Guangzhou.
