At the beginning of September 2016, Mahusai (died on September 25, 2017), Mayousu, Mayagei and others purchased the crime-making tools and daily necessities at the Tacheng South Market. On September 7, 2016, they rented a light truck and drove to the 11th company of 161 regiment of Xinjiang Production and Construction Corps. They illegally hunted and killed three rare and endangered wild red deer, obtained deer antler, deer whip and other red deer products. In the early morning of October 28, 2016, they called Yuping H. and asked him to transport red deer products to Tacheng. On November 9, 2016, when Zhonlong M. knew that Mahusai was being arrested by the public security organ, he still told his brother Jinshan M. the message by phone. Mayousu and Mayagei confessed to having illegally hunted threatened and endangered wildlife species, Yuping H. confessed to having covered up and concealed the proceeds of crime, and Zhonlong M. confessed to having harbored criminals.
