In mid-November 2015, Gamacida and Pingcuonanjia lived in temporary shelters for grazing. During the period, due to multiple incidents of missing and bitten sheep, Gamacida proposed to Pingcuonanjia to place iron clips for hunting wildlife to prevent them from infringing on the flock. Two iron clips were placed at a different location near the temporary residence. The next morning, Gamacida went to inspect the iron clip and found it was gone. He called Pingcuonanjia to look for it together. At hundreds of meters from the temporary residence, the two found that an animal resembling a cat was caught, and very fierce to get approached. Gamacida proposed to stone the animal in order to retrieve the iron clip borrowed from another person. The animal was killed by them. Afterwards, the public security organ arrested the two appellants based on the report. Gamacida and Pingcuonanjia confessed to having illegally hunted threatened and endangered wildlife species.
