The Baiyin serial murders, or called Gan-Meng 8.05 serial murders, has been considered to be the most infamous among the major criminal cases since 1949. Between May 26, 1988 and February 9, 2002, 11 women including an 8-year-old girl were found gagged, raped, and murdered, often by slitting their throats, and some of their bodies were mutilated brutally, resembling the infamous ＂Jack the Ripper＂ killings that occurred in London more than one hundred years ago. Nine of these 11 murders took place in Baiyin District of Baiyin City in the northeast of Gansu Province （Fig. la） and the remaining two murders occurred at Kundulun district of Baotou city, 675 km north-east of Baiyin City, in Inner Mongolia Autonomous Region （Fig. lb）. The criminal suspect preferred to pick the women dressed in red, followed them home, and then raped and killed them bloodily. Consequently, the Baiyin serial murders aroused much fear in Baiyin city where women were even afraid to walk alone in the streets.
