More on the suspected murderer-cum-game-show-contestant on China Daily here:
Authorities in Jilin, a city south of Heilongjiang province, said on Wednesday they detained Liu after they had received an anonymous tip more than a month ago from a viewer who had recognized the pudgy-faced contestant as a suspect in a murder case dating to the 1990s.
Although his formerly square jaw had since become rounded and his crewcut had been replaced with a more stylish buzz, his button nose and soft features had remained enough the same to give him away.
Police watched the tapes and found that Liu did indeed resemble Wu Gang, the suspect in a stabbing murder that occurred more than 13 years ago outside a restaurant in Jilin, said Li Ang, a police officer from the criminal investigation department of the Jilin Public Security Bureau.
