On the morning of November 25, a student surnamed Zeng went to the Jiangxi Street in Yiwu to catch rabbits at the Zongtang Fire Reservoir (3 United Reservoir). In the grass outside the Dongzheng Mountain Road on the east side of the reservoir, he discovered the body of a man. The police of the Criminal Investigation Division of the Yiwu Municipal Public Security Bureau arrived at the scene for investigation and found that the man had been dead for more than a month. Due to the high degree of decomposition of the corpse, it was impossible to identify his identity. To further their work, the Yiwu police issued a reward for clues.
The police quickly arrested Pei Jiankang and Wang Guanyun in Hangzhou and Yongxiang, Hebei. According to their confessions, the two saw that Chen Mou was beautiful, so they made improper advances and lured Chen up the mountain where they killed and harmed her before brutally disfiguring her face as they left. Afterwards, fearing that the matter would be exposed, they plotted to kill A Kang, who knew some details, but failed due to various reasons.
It was learned that the case, due to its heinous nature, drew significant attention from the police.
Upon investigation, it was found that the victim was an 18-year-old girl named Xiao Mou from Zhang County, Gansu Province. The police soon located the victim's boyfriend, A Kang. A Kang stated that on October 23, Chen Mou had played cards with A Kang's friends, Pei Jiankang and Wang Guanyun from Ningcheng. "The next day, these two individuals invited my friend up the mountain to pick oranges."
On December 14, a couple working in Yiwu came to the Criminal Investigation Division, claiming that they recognized the jeans and sweater worn by the girl.
In order to identify the deceased, the police not only issued a reward announcement in the media, but also distributed 30,000 flyers to gather clues, covering Yiwu and surrounding counties and cities.
Zhejiang Online News on December 20: Yesterday, reporters learned from the criminal investigation team of the Yiwu Municipal Public Security Bureau that the case has been successfully solved. The victim is an 18-year-old girl named Xiao Mou from Gansu Province. Both suspects, Pei Jiankang and Wang Guanyun, have been captured.
