China manhunt: Thousands of police dispatched to find serial killer

China is intensifying a massive manhunt to find a man suspected of as many as seven murders.

Chinese media report that more than 10,000 police have been dispatched to hunt for 42-year-old Zeng Kaigui, a former member of the Chinese armed police who is suspected of killing a man during a robbery near the southern city of Nanjing on Friday. Media reports say Zeng is being sought in connection with six other robbery/murders in western and central parts of China. The city of Nanjing has been plastered with wanted posters containing Zeng's face and details, and authorities have announced they are offering an award of almost $400,000.

Despite its massive population, publicized cases of serial killings are still somewhat rare in China.
